Dynamic multi-period recycling collection routing with uncertain material quality

Abstract We consider the problem of collecting and processing waste material. At a production facility, a known amount of inventory is required for production (e.g., paper) for every period. Instead of new material, the facility relies on collected and processed waste material (e.g., paper waste). This material is collected from regional waste collection locations. The amount of waste material per location is uncertain, as is the quality of the collected waste, i.e., the resulting inventory when processing the material. If the inventory is insufficient at the end of a period, costly new material must be bought. Each period, decisions are made about how much waste material to collect from which location and how to route the collection vehicles accordingly. Ideally, inventory is built to hedge against quality uncertainty and to ensure efficient routing operations in future periods. We propose a stochastic lookahead method that samples a set of scenarios and solves a simplified two-stage stochastic program in every period. We show the value of our method for two case studies, one based on real-world data from Sachsen-Anhalt, Germany, and one from the literature with data from the United Kingdom. We further conduct a detailed analysis of our method and the problem characteristics. The results show that our method effectively anticipates all sources of uncertainty, reducing cost significantly compared to benchmark policies. This superior performance is due to appropriate state-dependent supplier selection that considers the percentage of material loss, available material, and routing cost for current and future periods.

Bibliometric Analysis of Publications on Neglected Tropical Diseases in Nigeria Using Data from Dimensions Database

Background: Neglected Tropical Diseases (NTDs) are global public health problem and pose a significant burden on public health in Nigeria, necessitating research efforts to combat these diseases. This study aims to provide a comprehensive bibliometric analysis of publications on NTDs in Nigeria. Methods: Data was collected from Dimensions database on January 14, 2025, using the search term: (("Neglected Tropical Diseases" OR "Neglected Tropical Disease" OR NTDs) AND (Nigeria OR Nigerian OR Nigerians)). The search yielded 299 Publications (comprising data from January 1st, 2008 till the search date) and after manual cleaning and removal of duplicates, 242 publications remained. Microsoft Excel and VOSviewer software were used in data analysis for descriptive analysis and bibliometric mapping respectively. Results: The majority of publications (91.3%) were articles. PLOS Neglected Tropical Diseases emerged as the most productive source, with SNIP of 1.670 and SJR of 1.260. The year 2023 witnessed the highest productivity, with 42 publications. Racheal Thomson and Dean Laura were the most productive authors, each contributing 10 publications. At the institutional level, the Federal Ministry of Health, a Nigerian federal research institution, topped the list with 21 publications. Nigeria dominated the country-wise distribution, accounting for 61.57% of the total publications. Bibliometric mapping revealed co-authorship and co-citation patterns, highlighting clusters, links, and total link strength. Notably, Dean Laura and Racheal Thomson were the most collaborative authors, while the Federal Ministry of Health, Nigeria, and the Swiss Tropical and Public Health Institute were the most collaborative institutions. Furthermore, Nigeria, the United Kingdom, the United States, Switzerland, and China emerged as the most collaborating countries. Conclusions: This study revealed the trends, patterns, and collaborations in research on Neglected Tropical Diseases (NTDs) in Nigeria, answering the question of how NTD research has evolved in the country. The findings highlight the growing research output, international collaborations, and institutional commitments, which can inform research priorities, funding decisions, and capacity-building initiatives. By understanding the research landscape of NTDs in Nigeria, policymakers, researchers, and healthcare professionals can develop targeted strategies to address the burden of NTDs in the country.

Comprehensive analysis of endoscopic ultrasound (EUS) in mediastinal lesions: patient characteristics, diagnostic outcomes, safety, and efficacy: a multi-country study

BackgroundMediastinal lesions are tumors that develop mainly from structures commonly located in the three compartments of the mediastinum and the paravertebral areas. The diagnosis of these lesions is primarily based on imaging studies such as computed tomography and magnetic resonance imaging, which confirm the presence of the lesions and suspected metastatic disease. The study aims to determine the factors that determine the diagnostic accuracy and yield of endoscopic ultrasound (EUS) in diagnosing mediastinal lesions.MethodsThis multi-country study involved a list of centers providing EUS services across ten countries—the United Kingdom, Algeria, Egypt, Iraq, Kingdom of Saudi Arabia (KSA), Lebanon, Morocco, Pakistan, Romania, and Thailand. The appropriate information was collected regarding EUS-FNA and EUS-FNB procedures, including needle types, nature of lesion, needle passes, and complications of the techniques. The frequency/percentage conveyed data on the qualitative variables. The p-values were obtained using the Chi-square two-tailed exact test. The significance of the analysis was defined as p < 0.05. All the syntheses were performed using the Statistical Package for the Social Sciences (SPSS version 27; SPSS Inc., Chicago, IL, USA).ResultsA total of 439 participants were involved in this study, 255 (58.1%) males and 184 (41.9%) females, with a mean age of 55.73 ± 14.93 years. EUS-FNA and EUS-FNB diagnostic yield was influenced by needle types, needle size, number of needle passes, and lesion size. Among females, 44.6% were diagnosed with EUS-FNA, 42.8% with EUS-FNB, and 50.0% with EUS-FNA and FNB. Conversely, 55.4% of males were diagnosed using EUS-FNA and 57.2% with EUS-FNB. The association between gender and the diagnostic method, however, was statistically insignificant (p = 0.197). Needles with smaller diameters (22G) offered greater diagnostic yield than needles with larger diameters (19G). A minimal number of needle passes (between 2 and 4) showed a higher diagnostic yield than a higher number of needle passes (> 5). EUS-FNB accounted for a 0.5% complication incidence rate each for fever, pain, thoracic pain, and hemorrhage. EUS-FNA had no complication rate. Patients undergoing EUS-FNA, EUS-FNB, or both procedural examinations had no significant complications (p = 0.085).ConclusionThe diagnostic yield of EUS procedures is affected by needle types, number of needle passes, lesion size, and needle size. Besides, EUS-FNA and EUS-FNB are infrequently associated with various complication rates. These techniques are safe and offer higher diagnostic yield when utilized responsibly by endosonographers.

Citizen scientists mapping the United Kingdom's and Republic of Ireland's flat flies (louse flies) (Diptera: Hippoboscidae) reveal a vector's range shift.

Changes in climate may cause changes in the ranges, phenology and interactions of insects with other species and lead parasites to switch host species. A study of louse (flat) flies in the United Kingdom, Republic of Ireland and Isle of Man, in which licensed bird ringers acting as citizen scientists collected ectoparasites that left birds during ringing, showed recent range shifts of several species. The Common or Bird Louse Fly Ornithomya avicularia (Linnaeus, 1758), a vector of Haemoproteus sp. and trypanosomes, has undergone a major northwards range expansion of over 300 km in the United Kingdom (UK) since the 1960s. The Finch Louse Fly Ornithomya fringillina (Curtis, 1836) has also expanded its range over 300 km northwards and 400 km westwards into the Island of Ireland, and the Swallow Louse Fly Ornithomya biloba (Dufour, 1827) is now established in Wales and Southern England. The Grouse Louse Fly Ornithomya chloropus (Bergroth, 1901) has undergone a range contraction at lower altitudes and on the southern edge of its range. Other species of louse fly were detected: Crataerina pallida (Latreille, 1812), Stenepteryx hirundinis (Linnaeus, 1758), Pseudolynchia garzettae (Rondani, 1879) and Icosta minor (Bigot, 1858). Some generalist species have shifted their phenology, whereas the more specialist nest parasites of migrant birds have not, as the arrival and breeding dates of their hosts have not changed. The range changes of the generalist species of these ectoparasites may have implications for bird health, especially if they switch to new host species as their ranges shift.

National variation in delayed cord clamping implementation – A survey of the challenges in universal adoption of DCC in the United Kingdom

National variation in delayed cord clamping implementation – A survey of the challenges in universal adoption of DCC in the United Kingdom

There’s (not) an App for that: situating smartphones, Excel and the techno-political interfaces and infrastructures of digital solutions for COVID-19

This paper focuses on the operational-infrastructural puzzles of mHealth via COVID-19 Contact Tracing Apps (CTA). Significant literature exists on user adoption of the platformisation of public health during the pandemic, but there has been limited consideration of how those responsible for implementing CTA design, deployment, and use of public health infrastructures did so. We redress this imbalance by exploring some of the politics and practicalities of offering CTA as technical ‘solutions’ to pandemic problems. Our work adds to previous comparative analyses of mHealth by drawing on data from key actors across government, industry, and civil society involved in designing and implementing CTA into public health across 5 jurisdictions: Australia, Canada, New Zealand, Singapore, and the United Kingdom. While CTA research often frames tensions around efficacy and adoption (e.g. privacy trade-off), we find hidden infrastructural tensions within a situation of political and technical constraints in the ‘back end’ of the platformisation of public health. The paper offers new insights to pandemic politics by shifting questions from digital contact tracing and pandemic surveillance interfaces to understanding CTA as infrastructures of public health. While CTA user-software interactions produce certain research questions, querying the infrastructural complexity of digital public health projects require and produce a different set of data and knowledge.

Virtual Reality Simulation as a Tool for ENT Training: An Autoethnographic Study.

To investigate the factors influencing a novice trainee's surgical skill acquisition using virtual reality (VR) temporal bone (TB) drilling simulation as a training tool. This study is the first application of autoethnography in the surgical simulation literature. This study uses autoethnography to examine the factors underpinning simulated surgical skill acquisition using VR TB drilling (ethnography) through systematically documenting and analyzing the researcher's reflections over a prolonged period of time (autobiography). The primary researcher undertook 16 3-hour sessions learning to perform a virtual cortical mastoidectomy on the Voxel-Man TempoSurg (VMT) simulator over 8 months. Data collected comprised qualitative field notes and reflective journal logs, and quantitative scores from formative assessments. Data were coded using NVivo12 and analyzed using inductive thematic analysis. University Hospitals Birmingham ENT Simulation Dry Lab, Queen Elizabeth Hospital, Birmingham, United Kingdom. The primary researcher, a surgical novice, was responsible for the study design and execution, with supervision from a consultant ENT surgeon and 2 simulation fellows. The study yielded 6 themes: About 3 themes highlight new insights: 1) VMT as a surgical learning tool, 2) overcoming technological issues, 3) and physical impacts of simulated surgery; About 3 themes support existing evidence relating to surgical skill acquisition: 4) rushing leading to inaccuracy, 5) reflections and feedback, and 6) overcoming demotivation. The application of autoethnography to the study of surgical skill acquisition is new. Our results enable a deeper insight into surgical skill acquisition using VR TB simulation, with 6 specific themes identified as impacting learning with this tool. An understanding of these factors will facilitate future research in this area, and enable constructive adjustments to the learning experience, ultimately improving training program delivery and outcomes going forward.

Data-Sharing Statements Requested from Clinical Trials by Public, Environmental, and Occupational Health Journals: Cross-Sectional Study.

Data sharing plays a crucial role in health informatics, contributing to improving health information systems, enhancing operational efficiency, informing policy and decision-making, and advancing public health surveillance including disease tracking. Sharing individual participant data in public, environmental, and occupational health trials can help improve public trust and support by enhancing transparent reporting and reproducibility of research findings. The International Committee of Medical Journal Editors (ICMJE) requires all papers to include a data-sharing statement. However, it is unclear whether journals in the field of public, environmental, and occupational health adhere to this requirement. This study aims to investigate whether public, environmental, and occupational health journals requested data-sharing statements from clinical trials submitted for publication. In this bibliometric survey of "Public, Environmental, and Occupational Health" journals, defined by the Journal Citation Reports (as of June 2023), we included 202 journals with clinical trial reports published between 2019 and 2022. The primary outcome was a journal request for a data-sharing statement, as identified in the paper submission instructions. Multivariable logistic regression analysis was conducted to evaluate the relationship between journal characteristics and journal requests for data-sharing statements, with results presented as odds ratios (ORs) and corresponding 95% CIs. We also investigated whether the journals included a data-sharing statement in their published trial reports. Among the 202 public, environmental, and occupational health journals included, there were 68 (33.7%) journals that did not request data-sharing statements. Factors significantly associated with journal requests for data-sharing statements included open access status (OR 0.43, 95% CI 0.19-0.97), high journal impact factor (OR 2.31, 95% CI 1.15-4.78), endorsement of Consolidated Standards of Reporting Trials (OR 2.43, 95% CI 1.25-4.79), and publication in the United Kingdom (OR 7.18, 95% CI 2.61-23.4). Among the 134 journals requesting data-sharing statements, 26.9% (36/134) did not have statements in their published trial reports. Over one-third of the public, environmental, and occupational health journals did not request data-sharing statements in clinical trial reports. Among those journals that requested data-sharing statements in their submission guidance pages, more than one quarter published trial reports with no data-sharing statements. These results revealed an inadequate practice of requesting data-sharing statements by public, environmental, and occupational health journals, requiring more effort at the journal level to implement ICJME recommendations on data-sharing statements.

The quality, accuracy and appropriateness of UK optometric age-related macular degeneration referrals.

Little is known about the quality of optometrists' referrals to secondary care for neovascular age-related macular degeneration (nAMD), despite the need for timely intervention. We analysed the content and accuracy of optometrists' referrals for nAMD. Adherence to UK National Institute for Health and Care Excellence (NICE) guidelines and the impact of the COVID-19 pandemic were assessed as secondary measures. Optometric referrals to a specialist macular treatment centre in Bradford, United Kingdom, between March 2019 and March 2021 were retrospectively analysed and compared with subsequent electronic medical records. Data were extracted on legibility, reason for referral, patient and optometrist demographics, visual acuity, reported signs and symptoms, patient diagnosis and patient outcomes. Binomial logistic regression models were constructed to determine whether signs or symptoms noted in the referral were associated with subsequent nAMD diagnosis in secondary care and whether optometrist gender or experience influenced nAMD referral accuracy. Across all 394 referrals analysed, 256 were for nAMD. Referral accuracy for nAMD was 39.8% (95% CI [34.0%, 45.9%]), with the most common reason for misdiagnosis being dry AMD. However, 76.8% of patients referred for suspected nAMD were either treated in secondary care or observed over multiple visits. 20% of suspected nAMD patients were seen within the NICE recommended 14-day window pre-COVID, dropping to 5% during the pandemic (p < 0.001). Visual acuity was most strongly associated with nAMD diagnosis (χ2(1) = 13.71, p < 0.001) followed by macular haemorrhage (χ2(1) = 5.89, p = 0.02). Neither optometrist gender nor experience was significantly associated with confirmed nAMD. Legibility of referrals was 91-95% for patient details and 94-97% for the referring optometrist. Although the overall quality and legibility of optometrists' macular referrals to secondary care were of a high standard, the diagnostic accuracy of nAMD was below 40%. Referred visual acuity was the main sign/symptom associated with confirmed nAMD diagnosis.

Historical Development and Experience of Day Surgery in China: From the Perspective of Anesthesiologists.

Day surgery has become the main mode of surgery in American and European countries, but it is still in the early stage in developing countries due to the limitation of medical technology and the backward management concept. At present, day surgery accounts for more than 60% of elective surgery in many countries in Europe and North America and more than 85% in countries such as the United Kingdom and the United States. There are 8469 ambulatory surgery centers in the United States in 2023. In China, the first ambulatory surgery center was established in 2001. In 2018, more than half of the tertiary hospitals (high-level hospitals) in China carried out day surgery, of which 639 hospitals set up ambulatory surgery centers; the proportion of day surgery in elective surgery increased to 12.8%. The annual number of day surgeries exceeded 1.25 million. In 2022, our hospital established an ambulatory surgery center managed by anesthesiologists. Day surgery requires anesthesiologists to participate in the whole process of patient management from preoperative preparation to postoperative recovery. The establishment of ambulatory surgery centers managed by anesthesiologists is of great significance to China, developing countries, and the whole world. So this study aimed to review the development of day surgery in China, combine Chinese government policy evolution, summarize the management model of Chinese ambulatory surgery centers, guide the establishment of ambulatory surgery centers in low- and middle-income countries, and highlight and analyze the advantages of anesthesiologist-managed ambulatory surgery centers as distinct from other physician-managed ones. We call on anesthesiologists, other physicians, surgeons, nurses, and health system managers around the world to promote efficient, low-cost day surgery in developing countries and thereby increase access to surgical treatment for the world's poor.

Tick-borne encephalitis: from tick surveillance to the first confirmed human cases, the United Kingdom, 2015 to 2023.

BackgroundTick-borne encephalitis virus (TBEV) is a flavivirus spread by ticks and can cause tick-borne encephalitis (TBE) in humans. Previously, TBE has been reported in returning travellers in the United Kingdom (UK), but in 2019 and 2020, two probable cases of TBE acquired in the UK were identified.AimThe aim of this study was to investigate TBE cases in the UK between 2015 and 2023, describing the incidence, place and mode of acquisition and diagnostic process.MethodsA retrospective review of possible, probable and confirmed cases of TBE diagnosed by the Rare and Imported Pathogens Laboratory (RIPL) between January 2015 and December 2023 was performed. For cases identified in 2022 and 2023, clinical data were collected for enhanced surveillance using structured case record forms. Laboratory diagnosis is reviewed and described.ResultsWe identified 21 cases: three possible, seven probable and 11 confirmed cases. Of these, 12 were between January 2022 and December 2023: three possible, three probable and six confirmed cases. Two confirmed TBE cases had definite or highly probable acquisition in the UK, in June and August 2022, respectively. One of the possible cases had definite UK acquisition. Cases typically have a biphasic presentation, with encephalitis in the second phase.ConclusionClinicians should be aware of the possibility of TBE when the cause for encephalitis is not identified, even in the absence of travel to previously identified endemic regions.

"The three musketeers": A triadic analysis of parenting responsibilities within U.K. LGBTQ+ three-parent families.

Within the United Kingdom, alongside many other countries, it is legally and socially assumed that every child is born with two parents. Recently, there has been an increased societal interest in intentional multiparent families, where more than two adults are actively involved in coparenting a child, yet little research has explored experiences within these families. This study addresses this gap, exploring the way in which parenting roles and responsibilities are negotiated within lesbian, gay, bisexual, trans, queer and questioning intentional three-parent families in the United Kingdom. This article draws upon a unique data set of three-parent families, including interviews with 12 lesbian, gay, bisexual, trans, queer and questioning parents in four families in the United Kingdom. Data were analyzed using a novel analytical approach, qualitative triadic analysis, which allows for the analysis of participants' experiences at an individual and family level. Family systems theory and the underutilized theoretical concept of emotional triangles were used to make sense of the data. Three themes were identified in the data, all addressing the research question "How do three-parent families negotiate parenting roles and responsibilities?" Findings highlight that participants managed their parenting arrangement in two different ways, either sharing parenting responsibilities equally or dividing parenting roles, with primary and secondary caregivers taking on different responsibilities. Participants discussed the importance of flexibility and communication in managing their arrangement and all participants reported positive coparenting relationships. This study has a number of implications: Methodologically and theoretically, this study highlights the usefulness of systemic qualitative approaches to studying diverse families. Legally, findings highlight the restrictiveness of two-parent models. (PsycInfo Database Record (c) 2025 APA, all rights reserved).

Competitiveness And Competitive Strategies

The business competitiveness is one of the most recurrent study topics in the last century and a matter of great concern in Latin American countries, given the changing conditions of the markets. This article aims to analyze the relationship between the strategic management of organizations and business competitiveness in order to validate the most significant actions that medium and small-sized enterprises in Colombia can adopt. A descriptive bibliometric analysis of publications in Scopus on strategic management and competitiveness was conducted. VosViewer was used to determine the co-occurrence between terms and authors. In the chosen database, 7,877 publications were found, of which 7,134 correspond to strategic management and 743 to business competitiveness. The data show that scientific production on strategic management was primarily concentrated in the years 2019 and 2023, with 583 and 586 publications, respectively (508 on average per year), while in business competitiveness, the years 2020 and 2021 had the highest outputs, with 75 and 77 publications, respectively (55 on average per year). At a global level, the countries with the highest productivity in publications, based on the search equations, are the United States, China, and the United Kingdom, with 320, 128, and 122 publications, respectively, during the period from 2013 to 2023, totaling 2,649 authors cited in cross-references. Thus, it is concluded that, based on the bibliometric analysis conducted in VosViewer using the search equations, co-occurrences were identified in 275 keywords across 11 clusters, which link the concepts of business competitiveness with competitive strategy, strategic resources, organizational competitive dynamics, and strategic planning. Essentially, these co-occurrences allow a holistic, systemic, and complex approach to the topic of strategic business competitiveness in the current environments faced by SMEs, characterized by unpredictability, disruption, and turbulence. The limitations identified in the development of this bibliometric analysis are based on the identification and application of a systematic literature review methodology, which enables an effective and concise bibliometric analysis. Additionally, the potential research areas that can be addressed include strategic business competitiveness, applicable to all micro, small, and medium-sized enterprises.

Corporate carbon intensity and GDP contribution comparison across 4 countries

The paper analyzes the corporate carbon emissions and GDP contributions of the top ten companies by turnover for 2020–2023 in Germany, South Korea, China and the United Kingdom. Focusing on Scope 1, 2, and 3, the study explores the contribution of these companies to carbon intensity across different sectors and economies. The analysis shows that there are significant gaps in carbon efficiency, with the UK’s and Germany’s firms emitting the lowest emissions per unit of GDP contribution, followed by China and South Korea. Additionally, the study further examines the impact of Economic Policy Uncertainty on both firm carbon intensity and economic productivity. While EPU is positively associated with GDP contributions, its impact on emissions is nuanced. Firms apparently respond to policy uncertainty by increasing energy efficiency in direct (Scope 1) and energy-related (Scope 2) emissions but find it more difficult to manage supply chain emissions (Scope 3) in that case. The results point out the critical role of comprehensive ESG reporting frameworks in enhancing transparency and addressing Scope 3 emissions, which remain the largest and most volatile component of corporate carbon footprints. The paper then emphasizes the importance of standardized ESG reporting and bespoke policy intervention for promoting sustainability, especially in carbon-intensive industries. This research contributes to the understanding of how industrial and policy frameworks affect carbon efficiency and economic growth in different national contexts.

Swarm learning with weak supervision enables automatic breast cancer detection in magnetic resonance imaging

BackgroundOver the next 5 years, new breast cancer screening guidelines recommending magnetic resonance imaging (MRI) for certain patients will significantly increase the volume of imaging data to be analyzed. While this increase poses challenges for radiologists, artificial intelligence (AI) offers potential solutions to manage this workload. However, the development of AI models is often hindered by manual annotation requirements and strict data-sharing regulations between institutions.MethodsIn this study, we present an integrated pipeline combining weakly supervised learning—reducing the need for detailed annotations—with local AI model training via swarm learning (SL), which circumvents centralized data sharing. We utilized three datasets comprising 1372 female bilateral breast MRI exams from institutions in three countries: the United States (US), Switzerland, and the United Kingdom (UK) to train models. These models were then validated on two external datasets consisting of 649 bilateral breast MRI exams from Germany and Greece.ResultsUpon systematically benchmarking various weakly supervised two-dimensional (2D) and three-dimensional (3D) deep learning (DL) methods, we find that the 3D-ResNet-101 demonstrates superior performance. By implementing a real-world SL setup across three international centers, we observe that these collaboratively trained models outperform those trained locally. Even with a smaller dataset, we demonstrate the practical feasibility of deploying SL internationally with on-site data processing, addressing challenges such as data privacy and annotation variability.ConclusionsCombining weakly supervised learning with SL enhances inter-institutional collaboration, improving the utility of distributed datasets for medical AI training without requiring detailed annotations or centralized data sharing.

High-Altitude Retinopathy Presenting as Blue Spots with Prolonged Recovery: A Case Report.

Smith, Ben, Nicola Wetherill, and Daniel S. Morris. High-altitude retinopathy presenting as blue spots with prolonged recovery: A case report. High Alt Med Biol. 00:00-00, 2025.-High-altitude retinopathy (HAR) is a common ocular manifestation of high-altitude illness that is usually asymptomatic but can present with reduced or distorted central vision and signs of retinal vascular engorgement and retinal hemorrhages of varying severity. Typically, symptoms are very mild, such as a slight decrease in visual acuity or a small scotoma. There is no treatment for this condition, and most cases resolve spontaneously within 12 weeks without any permanent visual changes. Here we present a case of a previously fit and well 29-year-old female who developed atypical symptoms of "blue spots" in both eyes after ascending to 5,420 m. She descended promptly and was assessed in an emergency ophthalmology clinic in the United Kingdom (UK) upon her return. Her visual recovery was prolonged, which, combined with the presenting symptoms, makes this case atypical and assists in broadening understanding of HAR.

Using the Scopus database, this research analyzed 18,399 publications from 2013 to 2024, spanning multiple disciplines such as sociology, anthropology, and digital cultural studies. This study identified leading authors, collaboration patterns, and thematic evolutions within identity research, highlighted through citation analysis and network visualization. The findings reveal significant contributions from Western countries, particularly the United States and the United Kingdom, in shaping the global discourse on identity. Key topics frequently explored include social identity, cultural identity, and the influence of globalization. Additionally, emerging themes such as identity in the context of the COVID-19 pandemic and racial disparities are highlighted. This bibliometric analysis provides insights into global collaboration, research productivity, and the intellectual contributions of prominent scholars. Utilizing R software and the Bibliometric package, this study offers a deep understanding of the dynamics of identity research and suggests future directions to further explore the formation, negotiation, and expression of identity in an increasingly globalized world.

Self-efficacy in Online Learning: A Bibliometric Analysis

Whether synchronous or asynchronous, online learning utilizes various digital tools that significantly differentiate it from conventional offline learning. One critical factor influencing students' success in this environment is self-efficacy, which reflects their belief in their ability to perform learning tasks effectively. Despite increasing research on online learning self-efficacy, a comprehensive overview of its development and trends is needed. This study aims to analyze the research landscape related to online learning self-efficacy over the last five years, identifying key contributors, collaboration networks, and thematic research focuses. This study employs descriptive bibliometric analysis to systematically examine the growth, distribution, and impact of research in this field. Data was collected from major academic databases, focusing on publications between 2018 and 2023. Key parameters analyzed include publication trends, country-wise research output, institutional contributions, collaboration networks, keyword co-occurrence, and citation impact. Findings indicate a growing interest in online learning self-efficacy studies, particularly between 2018 and 2021. The United Kingdom leads in publications, while United States researchers engage in the most international collaborations. The Hong Kong Polytechnic University emerges as the top institution in this field. Most studies appear in education and technology journals, with commonly associated keywords including motivation, e-learning, self-concept, and self-regulated learning. Quantitative research dominates, as 84 of the 100 most-cited publications employ quantitative methodologies, with students as the most frequently studied sample group. These findings provide insights into scholarly trends, highlighting key contributors and research directions for future studies.
