Learning to cooperate against ensembles of diverse opponents

AbstractThe emergence of cooperation in decentralized multi-agent systems is challenging; naive implementations of learning algorithms typically fail to converge or converge to equilibria without cooperation. Opponent modeling techniques, combined with reinforcement learning, have been successful in promoting cooperation, but face challenges when other agents are plentiful or anonymous. We envision environments in which agents face a sequence of interactions with different and heterogeneous agents. Inspired by models of evolutionary game theory, we introduce RL agents that forgo explicit modeling of others. Instead, they augment their reward signal by considering how to best respond to others assumed to be rational against their own strategy. This technique not only scales well in environments with many agents, but can also outperform opponent modeling techniques across a range of cooperation games. Agents that use the algorithm we propose can successfully maintain and establish cooperation when playing against an ensemble of diverse agents. This finding is robust across different kinds of games and can also be shown not to disadvantage agents in purely competitive interactions. While cooperation in pairwise settings is foundational, interactions across large groups of diverse agents are likely to be the norm in future applications where cooperation is an emergent property of agent design, rather than a design goal at the system level. The algorithm we propose here is a simple and scalable step in this direction.

University Leadership: Transparency in Communication with External Stakeholders

The research offers valuable insights into the importance of transparency in building trust, accountability, and a positive reputation for universities in Ukraine. The relevance of this topic is underscored by the growing global emphasis on the need for higher education institutions to communicate transparently with external audiences, including prospective students, parents, funding agencies, and the general public. Transparency in financial operations, governance, and academic offerings has become crucial for universities to attract talented individuals, secure financial support, and develop lasting partnerships. The study’s methodology – the K-means clustering technique ‒ effectively assesses university transparency. It clusters institutions based on shared transparency characteristics, allowing for the identification of distinct patterns and the classification of Ukrainian universities into specific groups. This approach provided a comprehensive understanding of universities’ performance in external communication. The Elbow Method was employed to establish the ideal number of clusters, dividing universities into four main clusters, each demonstrating varying degrees of transparency. The findings revealed that universities across different clusters exhibited unique transparency profiles. While some universities performed exceptionally well across multiple transparency criteria, others showed significant shortcomings, particularly in budget reporting and staff transparency. The results indicated that some universities emerged as transparency leaders, serving as models for others, while those in lower-performing clusters require targeted improvements in their communication strategies. The study highlights the practical impact of transparency on university governance and engagement with stakeholders. Universities that prioritize transparency build trust with external audiences and strengthen internal decision-making processes. The clustering method provided essential insights into which institutions lead in transparency and where improvements are necessary, reinforcing that transparency is key to ensuring competitiveness within the higher education landscape. This research broadens the understanding of transparency in higher education, offering practical recommendations for universities seeking to enhance their external communication practices. The study underscores the importance of aligning these efforts with international transparency standards to ensure long-term success and maintain credibility in the increasingly competitive global academic environment.

The living centre: an innovative open-access model of breast cancer survivorship care.

People affected by breast cancer experience a multitude oftoxicities and unmet needs across physical, cognitive, psychosocial, and economic domains that adversely impact their quality of life. High-quality and diverse supportive care is required to improve outcomes and rehabilitation for people affected by breast cancer. However, the availability and access to high-quality supportive care services is limited due to factors including cost and demand. As such, many people affected by breast cancer do not receive optimal supportive care. The Think Pink Foundation facilitates free-of-charge supportive care services to breast cancer survivors, their families, and caregivers through 'The Living Centre'. Think Pink seeks to provide a high-quality survivorship care model that overcomes barriers associated with the economic burden of cancer. Within its suite of services, The Living Centre offers ongoing exercise classes, creative therapy, support groups, specialist breast cancer nurse consultations, wellness services, and education support through face-to-face and online service provision. This paper outlines the development, model of care, service provision, and planning for future outcomes and economic evaluation of The Living Centre as a supportive care model for others to consider establishing in their local context. This paper may therefore directly inform the development of cancer survivorship care services globally to increase equitable access to optimal supportive care.

Unveiling the gaps: Assessing LGBTQIA+ inclusivity on emergency medicine residency websites-An analysis of pronoun usage, diversity pages, and LGBTQIA+ sections.

Despite progress in promoting diversity, equity, and inclusion (DEI) in medical education, lesbian, gay, bisexual, transgender, queer/questioning, intersex, asexual, and more (LGBTQIA+) individuals remain underrepresented and often face barriers to equitable advancement. Emergency medicine (EM) residency programs are instrumental in creating inclusive environments that attract diverse applicants and support LGBTQIA+ trainees. Since the COVID-19 pandemic's shift to virtual recruitment, residency websites have become vital tools for communicating DEI initiatives. This study examines LGBTQIA+ inclusivity on EM residency websites, focusing on the visibility of resident pronouns, diversity pages, and LGBTQIA+ subsections. We conducted a review of 282 EM residency program websites listed on the Electronic Residency Application Service (ERAS) between August and October 2023. Websites were assessed for the presence of pronouns on resident biographies, dedicated diversity pages, and LGBTQIA+ content. Data were stratified by geographic region and analyzed using descriptive statistics. Among the websites reviewed, 4.3% displayed resident pronouns, 31.2% had dedicated diversity pages, and 3.9% included LGBTQIA+ subsections. The Midwest region had the highest proportion of programs featuring resident pronouns (5/70), while the West region led in diversity pages (14/32) and LGBTQIA+ content (4/32). The limited visibility of LGBTQIA+ content and pronouns across EM residency websites suggests an underutilization of online platforms to promote inclusivity. With virtual recruitment now standard, these websites are critical for conveying program culture to prospective applicants. Displaying pronouns, DEI pages, and LGBTQIA+-specific content can foster a welcoming environment and signal support to diverse applicants. Programs in regions with stronger DEI representation could serve as models for others, sharing best practices in promoting inclusivity. Enhancing DEI visibility on EM residency websites may positively influence perceptions and engagement among LGBTQIA+ applicants, fostering more inclusive and equitable training environments that align with the needs of diverse trainees in emergency medicine.

Ghana abortion care—a model for others: analysis of the 2017 Ghana Maternal Health Survey

Spiraling down: Fearful attachment style moderates the link between parental burnout and violence

AbstractObjectiveThe aim of the current preregistered cross‐sectional study was to examine whether in parents with high anxious (characterized with a negative model of self), dismissing (characterized with a negative model of others), and fearful attachment styles (characterized with a negative model of self and of others), the link between parental burnout and violence toward the offspring is stronger.BackgroundPast research has shown that parental burnout exacerbates violence toward the offspring, but the correlation is not perfect (r = .49), which suggests that not all parents in burnout out are violent, and that moderators might therefore be at play.MethodParticipants (N = 794) answered an online questionnaires one time, through Prolific. Parental burnout, violence, and attachment styles were measured through the Parental Burnout Assessment, the Parental Violence Scale, and the Relationship Questionnaire. Multiple regression analyses were performed to test the moderating role of anxious, dismissing, and fearful attachment styles.ResultsParental burnout and all attachment styles are significantly related to violence. However, only fearful attachment style significantly potentiated the relation between parental burnout and violence.ConclusionIn parents with high fearful attachment style, the link between parental burnout and violence toward the offspring is stronger. Results are discussed in light of the role of internal models of self and others.ImplicationsAnxious, dismissing, and fearful attachment styles should systematically be investigated when dealing with burnt out parents, as some may be associated with a higher risk of violence toward the offspring.

The Role of Neonatal Nurse Practitioners in the Implementation of a Bedside Point-of-Care Ultrasound Program.

Point-of-care ultrasound (POCUS) in the neonatal intensive care unit (NICU) is becoming increasingly utilized, with the focus of training aimed at physicians. However, the role of neonatal nurse practitioners (NNPs) in the development of POCUS programs is not well described. To describe the NNP role in the implementation of a NICU POCUS program and exemplify the potential to expand the professional scope and educational advancement of NNPs. In 2018, a multidisciplinary team assembled to develop a POCUS program in the NICU at Lucile Packard Children's Hospital (LPCH). Three NNPs received formal POCUS training in order to provide onsite training, perform and supervise POCUS imaging, and participate in quality assurance sessions. NNPs also assisted with the development of a REDCap database and imaging protocols. The LPCH POCUS NNP providers contributed to the advancement of the profession by practicing to the full scope of their role, providing leadership in program development, research, and education. Incorporating NNPs into the programmatic structure of a POCUS program can be a model for others. With advancing skill set, NNPs can be positioned to be national leaders and educators. NICUs developing POCUS programs can benefit from the integration of NNPs to serve as consistent content experts to expand the number of trained providers while assuring the quality of image capture. POCUS is becoming increasingly essential to the care of newborns. NNPs can play a central role in performing POCUS, participating in quality improvement and research, and educating other NICU providers.

An Effective Interprofessional Collaboration to Support African Refugee Students' Oral and Written Language and Social Integration

Purpose: Two faculty members collaborated to advance educational equity by providing a summer camp experience to prevent summer learning loss for African refugee students in preschool through high school. Both faculty members educate university students in graduate programs, one for students aiming to become educators of English to Speakers of Other Languages and the other for speech-language pathology students. Method: Speech-language pathology graduate students provided supports for oral and written language within Tier 1 of a multitiered systems of support framework during camp. Interventions were provided within the context of the camp activities, rooted in the constructs of contextualized intervention, implicit learning, and feedback-free learning. The speech-language pathology students collaborated with the faculty members, camp director, community members, and the campers. Results: The speech-language pathology students learned to provide language support in natural environments, analyze writing, recognize strengths and areas for growth in multilingual learners, establish rapport with individuals from cultural and linguistic backgrounds that differ from their own, collaborate with other professionals, and build campers' confidence and self-esteem. The campers expanded their vocabulary, syntactic, and narrative production and developed teamwork, collaboration, and leadership. Conclusions: This program can be a model for others aiming to collaborate to advance educational equity. Speech-language pathologists have an important role in collaborating with colleagues from other disciplines to provide programs for language and literacy support, even when the students do not have underlying language disorder.

How do food safety technical working groups within a One Health framework work? Experiences from Vietnam and Ethiopia

BackgroundPersistent challenges of fragmented, food safety management in low- and middle-income countries underscore the need for more robustly coordinated mechanisms. National food safety technical working groups, operating under a One Health framework, offer potential in streamlining coordination efforts to effectively address these challenges. However, more clarity regarding their formation and functioning is important for understanding how to best establish and support such groups. The aim of this study is to systematically document the development process of established groups in Vietnam and Ethiopia.MethodsWe assess the process used to establish and support the technical working groups against six critical success factors for multisectoral collaboration: drive change, define, design, realise, relate, and capture success. To do so, we review meeting minutes, Terms of Reference, and other related publications.ResultsThe analysis underscores the importance of financial and technical support by development partners in initiating working groups while also highlighting the challenge posed by the absence of legal frameworks to secure government commitment. Embedding the technical working groups within existing government structures – such as One Health platforms – from the outset could help to ensure the active participation and sustainability of such groups.ConclusionBoth Vietnam and Ethiopia have established operational and institutionalized technical working groups to bolster national food safety efforts under a One Health framework. The approaches employed in these countries could serve as valuable models for others seeking to establish comparable multisectoral collaborative mechanisms to address emerging health risks.

ARABIC POETRY IN TIMBUKTU DURING THE 19th AND 20th CENTURIES: A MODEL STUDY

The written Arabic literary tradition of the Malian desert in West Africa remains largely unknown to the region's inhabitants and the wider Arab and Islamic world. Despite its distance from the traditional centers of Arabic poetry in the Arabian Peninsula, this literature deserves far more attention than it has received. Unfortunately, it has not been given the scholarly consideration it deserves in the research and studies conducted on this country, which could reveal its unique characteristics as a form of Malian African literature written in Arabic and its undeniable value regarding its scientific, cultural, and historical significance. The people inhabiting the Malian desert, including the Soninke, the Berbers, and particularly the Tuareg tribes, developed an Arabic sensibility and literary flair, leading them to compose works in various genres, including religious, linguistic, and literary texts, all at a high level. They also served as living models for others when writing poetry in classical Arabic. The literary renaissance in the northern Malian region emerged in the first half of the 19th century, spearheaded by poets from prominent Arab tribes such as the Tuareg, the Ansar, and the Kunta, as well as their disciples and the 20th century witnessed the rise of numerous poets who excelled in various literary fields. Tuareg poets have written on different subjects, including love, praise, elegy, description, satire, supplication, and prayer. Their poems incorporate many rhetorical and stylistic devices and are characterized by their beauty and sweetness of style.

The Implications of Attunement and Understanding on Heidegger’s Viewpoint in Education

Heidegger in attunement and understanding quests genuine Dasein who disclosed to the world authentically. Definitely, Heidegger’s genuine Dasein is distant from Descartes subject and not considering its relationship with the world and people base on subject- object relationship. It is aware of its worldliness and its understanding of it, therefore cannot consider itself superior than other race and people or like the modern man cannot consider itself a model for others. Thus, it is possible to establish human relationships that are no longer based on the subject-object relationship. Hence, in this essay, these basic existentialia of human being studied and its educational implications are examined. As a philosophical research, attunement and understanding from Heidegger’s viewpoint are declared, and then in educational context some guidelines such as attention to students’ mood, interest, understanding, and interpreting are inferred for policy makers and for an effective curriculum. Moreover, drawing hermeneutical cycle of understanding the importance of students’ preconceptions is raised. Elaborating the process of evaluating and the worlds involved in learning canalso help teachers to be more fair and effective which are discussed in the paper.

Impacts Assessment of Farmers’ Knowledge in Using Pesticides on Agricultural Productivity in Bugesera District, Rwanda

Nowadays, the use of pesticides in modern agriculture has increased due to the heightened strain from insects and weeds on animal and crop health. This study aimed to assess the impacts of farmers' knowledge in using pesticides on agricultural productivity in the Bugesera district, the Eastern Province of Rwanda. Data were collected from the fifteen sectors of the study area using questionnaires, with 399 respondents selected through random and purposive sampling techniques. SPSS software was used for data analysis, which was summarized using contingency tables and graphs. Correlation analysis was done to assess the link between farmers' knowledge of pesticide use and agricultural productivity in across sub-locations. The study revealed that the level of pesticide use in the Bugesera district was very low, at just 17%, and only 22% of farmers had good level of knowledge about pesticide use. Vegetables were the first crops sprayed by farmers, accounting for 82% of the total crop types to which pesticides were applied in the Bugesera district. Moreover, vegetable yields increased from 9t/ha to 9.475 t/ha following pesticide application. The study found a significant positive correlation between farmers’ knowledge of pesticide use and agricultural productivity at the 0.01 level (r=0.509,p<0.01). Enhanced farmers’ knowledge of pesticide use and the proper application of pesticides can reduce yield loss and boost agricultural productivity. It is recommended that the Bugesera district can provide the incentive scheme to the innovative farmers and encourage them to serve as role models for others. This would promote the adoption of appropriate pesticide use practices and adherence to sound agricultural principles in chemical pesticide application.

Konsep Islam Wasathiyah Perspektif KH. Hasyim Muzadi (Telaah Surah al-Baqarah Ayat 143)

The number of extreme cases that occur in Indonesia is a focus for the author. It is a great achievement when Indonesia is able to survive in the midst of various differences it has, both race, religion, customs, foreign cultures and so on. However, it cannot be denied that sometimes conflicts in Indonesian society often occur both horizontally and vertically. This study, wants to try to explore the elements contained in the Qur'an, related to wasathiya Islam in the perspective of an Indonesian figure KH. Hasyim Muzadi who has a very strong influence in the establishment of interfaith relations and is one of the figures who often acts as a mediator in all matters relating to religion and the state. This research can be a driving force to form Muslims who are in the middle, not extreme right or extreme left and willing to accept various differences as long as they are in the level of khilafiyah. This research uses qualitative library research methods and content analysis. The formulation of the problems in this study are 1). what is the meaning of wasathiyah Islam. 2). How95Konsep Islam Wasathiyah Perspektif KH.Hasyim Muzadi…Muhamnad Al Fikri & Qathrunnadadoes KH. Hasyim Muzadi think about religious moderation (wasathiyah Islam). 3). How is the interpretation of Al-Qur'an surah al-Baqarah verse 143 about wasathiyah Islam?Primary sources in this study are books related to the thoughts of KH. Hasyim Muzadi including true Islam, Islam from the heart and various literature on wasathiyah Islam. The results of this research are (1) The results of the study prove that in the Qur'an wasathiyah Islam is explained in Q.s.al-Baqarah: 143. Interpreters explain that wasathiyah Islam is interpreted as a middle society, the chosen people, and the best people. The middle attitude is realized through several things, such as the middle in addressing the world and the hereafter, humans who reflect justice, and are able to be role models for others. (2) According to KH. Hasyim Muzadi, Allah has made Muslims the chosen people among other people. People who are able to apply 3 forms of justice, namely justice of equity, justice of equality and justice of balance (3) Indonesia's multiculturalism is not only an advantage, but also a challenge for Indonesian society. Answering these challenges, KH. A Hasyim Muzadi explained that the element of Wasathiyah Islam is a requirement to face the challenges faced by the Indonesian people.

Better together: A multistakeholder approach to developing specialty-wide entrustable professional activities in emergency medicine.

Entrustable professional activities (EPAs) are a widely used framework for curriculum and assessment, yet the variability in emergency medicine (EM) training programs mandates the development of EPAs that meet the needs of the specialty as a whole. This requires eliciting and incorporating the perspectives of multiple stakeholders (i.e., faculty, residents, and patients) in the development of EPAs. Without a shared understanding of what a resident must be able to do upon graduation, we run the risk of advancing ill-prepared residents that may provide inconsistent care. In an effort to address these challenges, beginning in February 2020, the authors assembled an advisory board of 25 EM faculty to draft and reach consensus on a final list of EPAs that can be used across all training programs within the specialty of EM. Using modified Delphi methodology, the authors came to consensus on an initial list of 22 EPAs. The authors presented these EPAs to faculty supervisors, residents, and patients for refinement. The authors collated and analyzed feedback from focus groups of residents and patients using thematic analysis. The EPAs were subsequently refined based on this feedback. Stakeholders in EM residency training endorsed a final revised list of 22 EPAs. Stakeholder focus groups highlighted two main thematic considerations that helped shape the finalized list of EM EPAs: attention to the meaningful nuances of EPA language and contextualizing the EPAs and viewing them developmentally. To foreground all key stakeholders within the EPA process for EM, the authors chose within the development process to draft; come to consensus; and refine EPAs for EM in collaboration with relevant faculty, patient, and resident stakeholders. Each stakeholder group contributed meaningfully to the content and intended implementation of the EPAs. This process may serve as a model for others in developing stakeholder-responsive EPAs.

A ‘Vocal Locals’ social network campaign is associated with increased frequency of conversations about mental health and improved engagement in wellbeing-promoting activities in an Australian farming community

BackgroundFarmers face numerous barriers to accessing professional mental health services and instead report a preference for informal support systems, such as lay or peer networks. Farmers also experience barriers to investing time in maintaining or improving their wellbeing, stemming from sociocultural norms and attitudes that are widespread in agricultural communities. The Vocal Locals social network campaign is an ifarmwell initiative that aims to promote conversations about wellbeing and challenge attitudes and behaviours that contribute to farmers’ poor mental health.MethodsThe Vocal Locals campaign was underpinned by the socio-ecological model which explains human behaviour as stemming from interactions between the individual, their closest social circle, the community, and broader society. The campaign ran in Loxton, South Australia, from June to August 2022. Ten community members (8/10 farmers) became ‘Vocal Locals’ and were supported to share ‘calls-to-action’ to encourage people in their social networks to engage in wellbeing-promoting activities. A broader communications campaign reinforced key messages and amplified Vocal Locals’ activities in the community. The intrapersonal and community-level impacts of the campaign were evaluated via pre- and post-campaign surveys of Vocal Locals and community members respectively.ResultsVocal Locals reported significantly lower psychological distress (p = .014), and higher positive mental wellbeing (p = .011), levels of general mental health knowledge (p = .022), and confidence helping someone with poor mental health (p = .004) following the intervention. However, changes in stigmatising beliefs about mental illness, confidence recognising poor mental health, and confidence and comfort speaking to others about mental health were non-significant. Community members who were familiar with the campaign reported having significantly more wellbeing-related conversations post-campaign compared to before (p = .015). Respondents also reported being more comfortable speaking to others about mental health or wellbeing (p = .001) and engaging more in activities to maintain or improve their wellbeing (p = .012) following the campaign.ConclusionsThe Vocal Locals social network campaign is an example of how science and community can be brought together to achieve meaningful outcomes. The campaign may serve as a model for others who wish to challenge attitudinal or knowledge-related barriers to help-seeking and improve engagement in wellbeing-promoting activities in difficult-to-reach communities.

Enriqueta Vásquez Digital History Project: Snapshots of an Immersive Experience

Abstract: This essay provides snapshots from the field that emerged from the Enriqueta Vásquez Digital History Project, an immersive field school focused on the archive of the life and works of Chicana feminist, activist, and author Enriqueta Vásquez. As a result of these collaborative efforts, her archive is now housed at the Center for Southwest Research at the University of New Mexico. A community-driven, collaborative, and interdisciplinary Chicana feminist praxis guided the field school, which was hosted in El Prado, New Mexico, at Las Pistoleras Instituto Cultural de Arte, and within the sacred landscapes of northern New Mexico. The snapshots shared here are from the group of Chicanas who have worked together in various capacities over the course of many years. The authors provide insights about this form of deliberate praxis as a potential model for others invested in community-centered archival work to follow and/or adapt.

Strategies to enhance treatment fidelity and music-based intervention reporting in dementia research.

Creative solutions are needed to address the well-being of the growing number of individuals living with dementia. Music-based interventions (MBIs) are promising and can be cost-effective; however, empirical evidence for MBIs is limited and published findings have not been widely translated into practice. Here, we describe how we implemented strategies to enhance rigor in a randomized clinical trial of an MBI for persons with dementia. We examined the impact of a singing-based MBI on feelings, emotions, and social engagement, relative to a non-music treatment (verbal discussion), delivered in small group format (25 minutes, 3 times/week for 2 weeks). We implemented National Institutes of Health Behavior Change Consortium strategies regarding: (i) design, (ii) interventionist training, (iii) treatment delivery, (iv) treatment receipt, and (v) treatment skills enactment. We applied the MBI Reporting Criteria including: (i) theoretical framework, (ii) musical content, (iii) dosage, (iv) interventionist, (v) treatment fidelity, (vi) setting, and (vii) delivery unit. We analyzed data with a separate linear mixed model for each dependent variable. 32 older adults with dementia (65-97 years) participated. The MBI yielded significant positive effects on all measured outcomes (all p's < .05). Application of established guidelines enhanced methodological rigor and MBI reproducibility. To support translation of research into practice, clinicians should understand how to implement an MBI reported in research. Our study illustrates practical steps to address the need for improved MBI research in persons with dementia and can provide a model for others to enhance evidence-based practice with this population.

Sustainable use of low-cost adsorbents prepared from waste fruit peels for the removal of selected reactive and basic dyes found in wastewaters

Agricultural wastes are potential sustainable adsorbents since they are available in large quantities, are low-cost, and may require little or no treatment, in some cases. In this study, several fruit peels, such as banana, orange, and pomegranate, were collected from local markets and prepared by a simple and eco-friendly method and used as natural adsorbents for the removal of both anionic (Reactive Red 120 (RR120), Reactive Black 5 (RB5), Remazol Brilliant Blue R (RBBR)) and cationic Methylene Blue (MB) dyes found in wastewaters. Many industries, such as leather and textiles, can release huge amounts of synthetic dyes into the wastewater during dyeing processes. These are one of the most important pollutants of water pollution as they cause enormous damage to the water body and also affect the health of organisms due to their toxicity and carcinogenicity. The search for a sustainable and at the same time efficient material for the removal of a wide variety of dyes is the innovation of this work. These peels were prepared by washing, drying, grinding, and finally sieving, under natural sustainable conditions. Porosometry (BET analysis), FTIR, SEM/EDS, and XRD techniques were used to characterize the fruit peels before and after the adsorption process. Factors affecting the adsorption of dyes (adsorbent dosage, pH solution, initial concentration of dyes, contact time, and temperature) were investigated. According to the results, in terms of the effectiveness of fruit peels as (natural) adsorbent materials, for anionic dyes, 5.0–6.0 g/L of banana or orange dry peels was sufficient to remove near or even more than 90% anionic dyes at pH 2.0, and 4.0 g/L was sufficient to remove 98% of cationic MB dye at pH 9.0. Similar amount of pomegranate peels had lower efficiency for anionic dyes (50–70%), while cationic MB was still efficiently removed (98%) at pH 9.0. Moreover, the adsorption process in all cases was found to better fit to pseudo-second-order model, in comparison to pseudo-first-order model. According to isotherms, Freundlich model fitted better in some cases to the equilibrium data, while the Langmuir model in others. Finally, this study demonstrates the viability of reusing the banana, orange, and pomegranate peel adsorbents for eight, four, and five cycles, showing a gradual reduction of around 50% of their effectiveness.Graphical

Low-carbon energy transition in oil-dependent African countries: implication on fiscal revenue

PurposeThe purpose of this study is to empirically analyse the fiscal revenue implications for oil-dependent African countries in the face of low-carbon energy transition (LET).Design/methodology/approachThe study combined the novel fully modified ordinary least squares, dynamic ordinary least squares and canonical cointegrating regressions estimators to analyse secondary data between 1990 and 2020 for the three major oil-dependent African Countries (Algeria, Angola and Nigeria).FindingsThe result shows that LET reduces oil revenue and non-revenue for specific countries (Algeria, Angola and Nigeria) and the panel, suggesting that low-carbon energy transiting is lowering the fiscal revenue of oil-dependent African nations.Research limitations/implicationsThe seeming weakness of this study is its inability to broaden the scope to include all oil-producing African economies. However, since the study selected Africa’s top three oil-producing states, the sample can serve as a model for others with lesser crude oil outputs.Practical implicationsOil-dependent African countries must urgently engage in sincere economic diversification in sectors like industry and manufacturing, the service sector and human capital development to promote economic transformation that will enhance fiscal revenue.Originality/valueWith the pace of energy transition towards low-carbon energy, it is not business as usual for oil-rich African countries (Algeria, Angola and Nigeria) due to fluctuating demand and price. As a result, it becomes worthy to examine how the transition is affecting oil-dependent economies in Africa. Also, this study’s method is unique as it has not been used in a similar study for Africa.
