Preparing Implementation of Transition Readiness Screening: What Do Paediatric Cancer Survivors and Caregivers Want?

Supporting transition from paediatric to adult healthcare is essential for the long-term well-being of paediatric cancer survivors. Guided by an implementation science approach, our overall programme of research seeks to integrate transition readiness screening in the routine care of paediatric cancer survivors, using the validated Transition Readiness Assessment Questionnaire (TRAQ). To plan for the screening implementation, the primary objective of this study was to first assess paediatric cancer survivors' current experiences with transition preparation and their preferences for screening and resources. A secondary focus group with parents was also conducted to complement youth perspectives. Focus groups were conducted with 14- to 18-year-old paediatric cancer survivors (n = 13) and parents (n = 6). Focus groups explored perceptions of care at the long-term follow-up clinic, transition preparedness, preferences for TRAQ administration (e.g., format, moment and location) and preferences for transition readiness resources. Interviews were analysed with an inductive thematic analysis approach. This study identified several barriers to TRAQ implementation, including adolescents' lack of transition awareness, attachment to paediatric care and parental distress. Unclear TRAQ items were also noted as a challenge for adolescents. Strategies to address these barriers include regular discussions with healthcare providers, a comprehensive transition resource website, addressing emotional needs, providing parent guidance and offering flexible TRAQ administration options, for example, by leveraging technology (QR codes, choice of online or paper administration). This study highlighted the importance of addressing the informational and emotional needs of adolescents and parents for implementation, notably by engaging in discussions with clinicians and tailoring online transition readiness resources. Preferences and suggestions for TRAQ administration and resources will be integrated to align with patients and parents' needs and optimize implementation. The study identified key barriers to TRAQ implementation, including paediatric cancer survivors' lack of awareness of transition and understanding of the TRAQ, attachment to paediatric care and parental distress about long-term follow-up. Participants suggested strategies such as offering the TRAQ online, integrating it into wait times and enhancing awareness through individualized discussions. Addressing emotional needs through dedicated resources and incorporating discussions about transition-related distress into the TRAQ implementation process is crucial. Participants preferred online resources over paper formats, and a webpage on transition resources was acceptable to both adolescents and parents. Results of this study are an essential first step in the preparation of a successful TRAQ implementation, with findings allowing better planning and adaptation of implementation to the local context and to adolescents and parents.

Determinants that impact the use of social media for mental health promotion amongst young people: A scoping review protocol

Background Adolescence is a period of transition in which young people undergo physical, psychological and social changes. While most move through this transition with few problems, others experience greater difficulties, which may lead to an increased risk of becoming vulnerable to mental health issues. Social media use amongst young people is high; an abundance of literature identifies the deleterious impact of its use on mental health. However, its positive influence on youth well-being is also reported. Ireland’s mental health policy recommends harnessing the positive role social media can play in the promotion of youth mental health. However, an evidence gap exists as to how this can be implemented. This scoping review aims to identify the barriers and enablers to the use of social media as a youth mental health promotion tool, to inform the implementation of policy recommendations. Methods The search strategy, screening, extraction and synthesis will be informed by the JBI guidelines. The Consolidated Framework for Implementation Research will guide the identification and mapping of implementation determinants. The review outcomes will be reported using the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for Scoping Reviews guidelines. Primary studies focused on young people and key stakeholders, such as teachers and parents, identifying barriers and enablers to the use of social media for youth mental health promotion will be included. A librarian-developed search strategy will be applied to the Web of Science Core Collection, Medline (EBSCO), Embase, PsycINFO and CINAHL databases. A narrative synthesis of the results guided by CFIR framework will be presented. Conclusion The review extends the work of previous reviews by adopting an Implementation Science approach focusing on the identification and mapping of implementation barriers and enablers to the use of social media as a youth mental health promotion tool.

Keadilan dalam Akses Pelayanan di Daerah Dalam Perspektif Filsafat Ilmu Berdasarkan Ilmu Hadis

Fairness in access to public services is one of the important indicators in realizing social welfare. In various regions, especially remote or underdeveloped areas, there is still inequality in access to basic services such as health, education, and government administration. This study aims to examine fairness in access to services in the regions through a philosophy of science approach that includes aspects of ontology, epistemology, and axiology, and is reviewed from the perspective of hadith science. In the perspective of hadith science, many narrations emphasize the importance of leaders being fair to their people, including in the distribution of services. The hadith of the Prophet Muhammad SAW which states that "Each of you is a leader, and every leader will be held accountable for his leadership" is a strong moral foundation in the context of equal distribution of services. This study concludes that the realization of justice in public services requires integration between scientific approaches, state ethics, and prophetic values reflected in Islamic teachings.

Citizen science substantiates jellyfish occurrence in the Mediterranean Sea

In recent decades, gelatinous plankton blooms have attracted media attention due to their damaging effects on fisheries, aquaculture, tourism, human health and power/desalination plants. The scientific community often failed to recognize the rise of jellyfish, due to difficulties in monitoring their appearances and disappearances. In Italian waters, a citizen science approach was employed to monitor the presence and distribution of gelatinous zooplankton over wide spatio-temporal scales. From 2009 to March 2016, citizens identified 27 jellyfish taxa and documented their geographical distribution and seasonal occurrence across the Italian Seas. The main blooming species was Pelagia noctiluca (30% of total sightings), mainly distributed in the western Mediterranean, followed by Rhizostoma pulmo (28% of total sightings), showing a more widespread distribution. Mnemiopsis leidyi, the main Non-Indigenous Species (NIS), initially reported in the western Mediterranean, since 2016 expanded its distribution to the east. Jellyfish blooms were recorded year-round, mainly between late spring and autumn. Jellyfish hotspots were identified in the northern and southern Tyrrhenian, Ligurian Sea, and northern Adriatic regions. Citizen Science enables the detection of phenomena that can be studied more in-depth by professional scientists, leading to the discovery of previously unknown species and a better understanding of the occurrence of bloom events.

Education as a Space for Critical Formation in the Technoscientific Era: Contributions of the Science, Technology, and Society (STS) Approach to the Construction of an Active and Reflective Citizenship

Objective: This article aims to critically analyze the interrelationship between education, science, technology, and society (STS), highlighting how the incorporation of the STS perspective into the educational environment can contribute to the formation of critical, conscious, and socially engaged individuals. It seeks to understand how the STS approach can be applied in pedagogical practice, promoting an education that engages with the ethical, social, and cultural challenges imposed by contemporary scientific and technological advances. Additionally, the study aims to identify the potentialities and limitations of this approach, as well as propose pathways for its consolidation in educational policies and practices. Theoretical Framework: The STS (Science, Technology, and Society) approach offers a critical interpretation of the role of computational technologies in contemporary society, emphasizing that such innovations are not neutral but are the result of specific historical, political, and cultural contexts. From this perspective, computational technologies should be examined in relation to the interests they represent, the social impacts they generate, and the inequalities they may either reinforce or mitigate. In contrast to a technicist view, which sees technological advancement as an end in itself, the STS field encourages ethical, democratic, and participatory reflection on the processes of development and application of these technologies, aiming to build a more equitable and conscious relationship between science, technology, and society. Method: This research is characterized as a qualitative, exploratory study with a bibliographic foundation. This methodological choice is justified by the need to investigate, in a critical and in-depth manner, the various dimensions involved in the interrelationship between education, science, technology, and society, particularly from the perspective of the STS approach. The study is based on the analysis and interpretation of academic works, scientific articles, and relevant documents, with the aim of identifying theoretical contributions, pedagogical possibilities, and challenges related to the implementation of the STS perspective in the educational field. Results and Discussion: The findings of this research indicate that incorporating the STS approach into the educational environment plays a fundamental role in the critical development of students, expanding their understanding of the significance of science and technology in social contexts. It was observed that when exposed to pedagogical practices that link scientific knowledge with social and ethical issues, students develop a deeper awareness of the effects of technological innovations on their lives and surroundings. This awareness promotes reflective thinking, active citizenship, and informed decision-making, especially in a context marked by rapid technological change. Research Implications: For academia, this study contributes to expanding the debate on methodologies and content that integrate science, technology, and society, encouraging the construction of interdisciplinary and contextualized curricula capable of forming more conscious and engaged individuals. For society, it is suggested that a critical and STS-informed education can strengthen civic participation and more informed and responsible decision-making in the face of contemporary challenges. Furthermore, the research highlights ongoing challenges, such as the need for adequate teacher training to mediate this approach, and emphasizes the urgency of educational policies that incorporate STS at different levels and modalities of education. Thus, the investigation not only deepens theoretical understanding but also points to the practical transformation of education as a tool for social and technological emancipation. Originality/Value: This research is original in its integrated articulation of education and the Science, Technology, and Society (STS) approach within the context of the technoscientific era, highlighting its transformative potential for the development of a critical and participatory citizenship. It stands out by emphasizing not only the transmission of scientific and technological knowledge but also the incorporation of ethical, social, and political reflection on the impact of these fields on everyday life, thereby expanding the traditional scope of education.

High-Accuracy Polymer Property Detection via Pareto-Optimized SMILES-Based Deep Learning

Polymers have a wide range of applications in materials science, chemistry, and biomedical domains. Conventional design methods for polymers are mostly event-oriented, directed by intuition, experience, and abstract insights. Nevertheless, they have been effectively utilized to determine several essential materials; these techniques are facing important challenges owing to the great requirement of original materials and the huge design area of organic polymers and molecules. Enhanced and inverse materials design is the best solution to these challenges. With developments in high-performing calculations, artificial intelligence (AI) (particularly Deep learning (DL) and Machine learning (ML))-aided materials design is developing as a promising tool to show development in various domains of materials science and engineering. Several ML and DL methods are established to perform well for polymer classification and detection presently. In this paper, we design and develop a Simplified Molecular Input Line Entry System Based Polymer Property Detection and Classification Using Pareto Optimization Algorithm (SMILES-PPDCPOA) model. This study presents a novel deep learning framework tailored for polymer property classification using SMILES input. By integrating a one-dimensional convolutional neural network (1DCNN) with a gated recurrent unit (GRU) and optimizing the model via Pareto Optimization, the SMILES-PPDCPOA model demonstrates superior classification accuracy and generalization. Unlike existing methods, our model is designed to capture both local substructures and long-range chemical dependencies, offering a scalable and domain-specific solution for polymer informatics. Furthermore, the proposed SMILES-PPDCPOA model executes a one-dimensional convolutional neural network and gated recurrent unit (1DCNN-GRU) technique for the classification process. Finally, the Pareto optimization algorithm (POA) adjusts the hyperparameter values of the 1DCNN-GRU algorithm optimally and results in greater classification performance. Results on a benchmark dataset show that SMILES-PPDCPOA achieves an average classification accuracy of 98.66% (70% Training, 30% Testing) across eight polymer property classes, with high precision and recall metrics. Additionally, it demonstrates superior computational efficiency, completing tasks in 4.97 s, outperforming other established methods such as GCN-LR and ECFP-NN. The experimental validation highlights the potential of SMILES-PPDCPOA in polymer property classification, making it a promising approach for materials science and engineering. The simulation result highlighted the improvement of the SMILES-PPDCPOA system when compared to other existing techniques.

Shining a Light on Daytime Coral Spawning Synchrony Across Oceans

ABSTRACTAimThe variety of coral taxa and environmental cues triggering broadcast spawning gave rise to contrasting theories about coral reproduction synchrony. Here, we shine a new light on this synchrony across oceans by highlighting how environmental cues modulate spawning time at various spatial scales in an understudied yet abundant gonochoric species.LocationSouth Indian and Pacific Oceans.Time Period2014–2023.Major Taxa StudiedPorites rus .MethodsPorites rus daytime spawning was investigated using a non‐invasive citizen science approach (> 300 voluntary observers) at colony, reef, island and ocean scales. Spawning time was recorded between 2014 and 2023 at a total of 104 reef locations from 15 islands in three countries and multiple depths across the Indian and Pacific Oceans. Statistical models were employed to assess the relationships between spawning time and depth, light and sea surface temperature at different spatial scales, and in both male and female colonies.ResultsSpawning occurred synchronously for colonies located a few meters to > 15,000 km apart, monthly 5 days after full moon over an extended, uninterrupted period from October to April. Strong linear relationships between depth, light, water temperature and spawning time after sunrise held at the different spatial scales for both males and females, which spawned ca. 20 min apart. Interestingly, single colonies spawned across consecutive days and months.Main ConclusionsThe largest data set for a daytime coral species compiled here allows extremely accurate predictions of P. rus spawning months, days and time (minute‐level precision) at different locations and depths in the Southern Hemisphere, facilitating field observations and experiments. Previously underexplored, the highly effective reproductive strategy of P. rus may explain its broad distribution and persistence in stressed environments, positioning it as an invaluable model organism for studying the physiological and genetic processes driving behavioural synchrony and biological rhythms across interconnected biogeographical regions.

The History of Islamic Education in Minangkabau: The Impact of the Paderi Movement on the Shift in Scholarly Orientation of Minangkabau Ulama

The Paderi Movement was an Islamic purification movement that emerged in 19th-century Minangkabau, influenced by Wahhabi teachings. This study aims to analyze the shift in the scientific orientation of the Paderi Movement regarding the development of Islam in Minangkabau, particularly in the context of social conflict, changes in religious structures, and contributions to the modernization of Islamic education. Data collection was conducted through a literature study using manuscripts and books written by Minangkabau scholars from the 19th to the 20th century, which serve as historical documents. The analysis employs historical methods, applying heuristic techniques, source criticism, interpretation, and writing, with a social science approach to examine historical understanding empathetically (verstehen). The findings indicate that the Paderi Movement had a significant impact on the development of Islam in Minangkabau. Despite its proselytization methods causing conflicts with traditionalist groups and Sufi orders, the movement successfully introduced a more Sharia-based interpretation of Islam and promoted the modernization of Islamic education. Thus, the Paderi Movement was not merely a socio-religious phenomenon but also played a crucial role in shaping the intellectual structure of Islam in Minangkabau.

Physiologically Based Biopharmaceutic Lung Deposition Modeling to Guide Clinical Device Transition of Protein A from a Nebulizer to a Dry Powder Inhaler.

Development Protein A (DPA) is a novel therapeutic biologic designed for inhaled administration. In phase I clinical studies, the DPA solution is administered using a continuous-output nebulizer. In subsequent studies, DPA is planned to be administered as a spray-dried powder formulation by using a dry powder inhaler (DPI). The implications for human drug product performance, such as regional lung dose, pharmacodynamic (PD), and pharmacokinetic (PK) parameters, when transitioning from a nebulizer to a DPI should be understood to maintain safety and efficacy. Here, we present a physiologically based biopharmaceutic modeling (PBBM) analysis linking in vitro and in vivo drug product performance. Specifically, PBBM is used to predict regional lung dose deposition from two early-stage drug products, namely, a continuous nebulizer and a DPI. The predictions were subsequently tested in a clinical PK bridging study, and the difference between nebulizer and DPI lung deposition patterns was used to investigate whether the total, central, or peripheral lung dose drives systemic exposure. To select clinical study doses, LungSim/GIsim, an AstraZeneca proprietary PBBM platform, was used to link device-metered dose to (regional) lung dose by simulating the interplay between lung morphology, inhalation maneuver, and in vitro-measured aerosol properties. DPA PK profiles were determined from healthy volunteers dosed on separate occasions using a nebulizer or a DPI. The total lung dose was predicted to be similar; however, the nebulizer was predicted to deposit the total lung dose more centrally in the lung compared to the DPI (which deposits more peripherally). Since the predicted total lung dose and observed PK parameters are comparable between the DPI and nebulizer, we suggest that systemic exposure and Cmax are driven by the total lung dose and that changes to aerosol properties are unlikely to impact PK parameters as long as the total lung dose remains unchanged. Consequently, the presented PBBM analysis can help anticipate the impact of early-stage aerosol property changes on lung dose and PK parameters. As development progresses, additional critical product attributes are determined and PD parameters investigated, which need to be incorporated into the PBBM analysis and thus linked to previously established relationships between the drug product, PK, and PD. When taken together, the overall knowledge can be used to support science and risk-based approaches during pharmaceutical development. This could include, but is not limited to, avoiding unnecessary PK and PD bridging studies between clinical phases, which could accelerate the availability of novel drug products for patients.

Developing Sapawarga As Value Orchestration Platform Using Service Science Perspective (Case Study Of West Java Provincial Government)

SAPAWARGA is part of the Jabar Super Apps initiative that created to improve access to public services in West Java by integrating multiple government services into one platform. Despite its potential, SAPAWARGA faces several challenges. First, user acquisition remains below its market potential, with only 2.82 million registered users as of 2024, a number that falls short of its estimated reachable market of 4 million users. Second, user engagement is low, with only 10.23% of registered users actively using the platform weekly. These issues highlight a disconnect between the platform’s offerings and the needs of its target audience. This research seeks to address these gaps by adopting a Service Science approach. Frameworks like Value Co-Creation and Value Orchestration Platform (VOP) are applied to explore strategies for aligning the platform with user expectations. In addition, the Customer Empathy Map is used to gain deeper insights into users' perspectives and refine the features of the platform to better meet their needs. Using qualitative methods such as interviews with users and service providers, this study presents actionable recommendations to improve SAPAWARGA. The recommendations include improving the platform's service design, encouraging stronger collaboration among stakeholders, and optimizing resource integration. By addressing these issues, SAPAWARGA can evolve into a more engaging and impactful digital public service solution, and realize its potential to serve West Java’s digitally savvy population.

Sociophysical Methods in Science and Technology Studies

Sociophysics is considered a promising interdisciplinary field applying physical methods to analyze social systems, particularly in the context of science and technology research. This text traces the historical development of sociophysics, from the ideas of D.Hume to contemporary approaches based on big data analysis. The author discusses key sociophysical models and methods, including cellular automata, the Ising model, agent-based models and self-organization models, as well as their application in the study of scientific collaborations, patent activity and other aspects of the development of science and technology. The importance of participatory projects (‘citizen science’) and the necessity of integrating sociophysical methods with traditional social science approaches are emphasized, in order to avoid reductionism and gain a more comprehensive understanding of intricate social phenomena.

STEM Education With a Focus on Equity and Justice: Traditional Approaches, Contemporary Approaches, and Proposed Future Approach

ABSTRACTThe disproportionate impacts of societal challenges (e.g., climate change, air and water pollution) on minoritized groups expose systemic injustices and compels STEM educators to reframe the role of STEM education in society. In this article, we describe traditional approaches, contemporary approaches, and our proposed future approach in science and STEM education with a focus on equity and justice. First, we begin with conceptual framing for equity and justice. Second, for each era (traditional, contemporary, future), we describe the intersections among (a) what counts as science and STEM subjects; (b) what role phenomena, problems, and societal challenges play in science and STEM education; and (c) how students learn science and STEM subjects. Traditional approaches in science education focused on learning canonical knowledge of science. Contemporary approaches, based on A Framework for K‐12 Science Education and the Next Generation Science Standards, center equity by providing opportunities for all students to make sense of phenomena in science and design solutions to problems in engineering. Going beyond contemporary approaches and complementing other research programs that share a commitment to justice, we propose a potential future approach—justice‐centered STEM education—that addresses societal challenges by leveraging multiple STEM subjects while centering justice. Finally, we close by calling for the science and STEM education communities to address increasingly complex societal challenges by centering justice for minoritized groups.

Eco-STEAM: A STEAM-based digital learning website for ecosystem topics

This study aims to develop Eco-STEAM, a digital learning website based on the Science, Technology, Engineering, Arts, and Mathematics (STEAM) approach, specifically designed to support ecosystem learning. The development process was carried out using the Research and Development (R&D) method, employing the 4D model, which includes the stages of define, design, develop, and disseminate. The developed media was evaluated for feasibility by experts in material, media, and language aspects, and the development testing involved teachers and students. The average assessment results by the experts across all aspects were categorized as highly feasible (94.75%). The results of the development trials conducted by biology teachers, small group trials, and large group trials also received an average rating in the highly feasible category (90.33%). The effectiveness of the media in enhancing students' understanding of ecosystem concepts was measured on a small scale using a one-group pretest-post-test research design. The dependent t-test and effect size test results showed a significant improvement in students' understanding of ecosystem concepts after using the Eco-STEAM media, with a strong effect size. These findings demonstrate that Eco-STEAM is a validated, feasible digital learning website that effectively enhances students' understanding of ecosystem concepts. This product can also enrich biology learning media and support more interactive and contextual learning, particularly in ecosystem topics.

Thought-forms and Primary Mental Cognitions as a Basis for the Formation of the Way Culture Knows the World

The study puts forward a number of hypotheses that can explain the nature and formation of thought-forms and mental cognitions as the basis on which a culture creates its unique way of knowing the world. The hypotheses were derived from a comparison of metaphysical and natural science (evidence-based) approaches. These scientific approaches identified three chronological types of civilisations that exist today. These civilisations still today use three different generalised ways of knowing the world. The way of knowing the world is determined by thought-forms, which are filled with basic (primary) cognitions. Thought-forms are universal for all mankind, but their cognitive content is unique for each culture. Thought-forms are organised in human psychic matter. They are filled with basic cognitions due to the matrix structure of psychic matter. Cultures develop around the way of knowing the world formed at the dawn of their birth. Cognitions that arise in the mental field as a functional of psychic matter are built exceptionally according to the already existing template, which is the way of knowing the world.

Complementing community science with xenomonitoring: Understanding the eco-epidemiology of Dirofilaria immitis infection in dogs and mosquitoes

BackgroundDirofilariosis is an emerging mosquito-borne disease that particularly affects domestic dogs worldwide but also causes symptoms in humans. Monitoring the distribution of emerging pathogens is essential for understanding the environmental and ecological factors influencing their transmission, which can be used to develop better prevention strategies.MethodsWe applied both community science and molecular xenomonitoring to assess the occurrence of Dirofilaria immitis in domestic dogs and mosquitoes.ResultsAs part of the community science approach, we collected infection data from 1491 dogs from owners across Hungary, using a questionnaire survey. We found that 321 dogs (21.5%) tested positive for current or past dirofilariosis infection, with the highest prevalence observed in the southeastern (47.8%) and the eastern regions (43.4%) of the country. Age and living conditions affected infection status, with older dogs (aged 5–10 years and over 10 years) and those kept exclusively outdoors showing significantly higher infection rates. Molecular xenomonitoring revealed D. immitis infection in Aedes albopictus, Aedes koreicus, and Aedes vexans, with the highest minimum infection rate (MIR) in Ae. koreicus (28.5). Similar to community science results, the highest infection rates were observed in the southeastern and eastern regions (MIR: 14.9 and 11.6, respectively), but the two approaches generally provided overall similar geographical patterns.ConclusionsWhile xenomonitoring did not detect infections in Central Transdanubia, community science successfully provided host infection data, demonstrating its usefulness in assessing the presence and distribution of the disease. Finally, we emphasize the value of using an integrative approach, combining community science and xenomonitoring for monitoring dirofilariosis, especially in areas where direct pathogen screening is unavailable.Graphical

An Implementation Science Approach to Promote Bedside Interprofessional Rounding.

Lack of interprofessional communication in the neonatal intensive care unit (NICU) can result in delayed treatments, misdiagnoses, medication errors, patient injuries, and/or death. One approach to facilitate effective communication between team members and caregivers is the use of bedside interprofessional rounding (BIPR). The purpose of this project was to standardize and increase BIPR participation with an implementation science approach. Secondary goals included measuring the impact of BIPR on central line dwell time and patient length of stay (LOS). The implementation of a BIPR checklist in the electronic health record (EHR), supported by other implementation strategies (eg, Situation, Background, Assessment, Recommendations reporting tool, staff education, audit & feedback, and leadership engagement), was utilized to standardize rounding. Pre- and post-implementation data were analyzed for BIPR usage and quality metrics related to central line dwell time and patient LOS. On average, the BIPR checklist was utilized 87% during the first 6months of deployment, with fluctuation in the weekly/monthly usage due to rounding team schedules. The BIPR checklist led to a 10.5% increase in nurse participation during rounds, 15hours less average central line dwell time, and standardization of the rounding process as reported by team members, and no difference in LOS. NICUs can individualize BIPR using implementation science strategies to enhance rounding standardization and improve specific neonatal outcomes. Based on these findings, tools to standardize and promote BIPR, along with staff education, audit & feedback, and leadership support, may benefit NICUs.

Engineering Visual Presentation E02: Repurposing fields for CO2 storage: well integrity risk assessment across the lifecycle

Engineering Visual Presentation E02 Repurposing existing fields for CO2 storage presents an appealing alternative to drilling new wells, offering potential project cost reductions and acceleration of timelines. Several driving factors, including timing, cost, regulatory considerations, risk reduction, and enhancing health, safety, and environmental outcomes, influence developers’ interest in well repurposing. Assessing the feasibility of this approach requires careful examination of legacy wells in the field for ongoing well integrity and CO2 containment risk. The viability of repurposing wells as CO2 injectors relies on thorough technical analysis of well barrier qualification, materials selection, cement evaluation, and monitoring requirements. This paper discusses a case study of how comprehensive technical assessment, enhanced by a data science approach to improve efficiency of processing many historical well records and automatic generation of well barrier schematics, standardised qualitative and quantitative risk assessments, enabling prevention and mitigation strategies where repurposing emerged as a viable option for CO2 storage projects. This process covers all legacy wells (abandoned, suspended, and potential injectors) for their carbon capture, utilisation, and storage (CCUS) specific well integrity failure modes and consequences. Recommendations for ongoing temporary or permanent abandonment are provided to reduce risk to as low as reasonably practicable (ALARP). Repurposing existing wells as CO2 injectors is risk assessed based on potential failure modes from corrosion, elastomer compatibility, cement quality, tubing and packer stresses to inform design and monitoring decisions.

The holistic enterprise management approach: including labor migration into modeling the dynamics of the influence factors on functioning

Today, enterprise management at all levels is focused on achieving specific goals, in particular by quickly responding to any deviations in the established indicators in order to eliminate the problem by making adequate decisions. In conditions of maximum imbalance of the economic situation in the country, which, for example, is a consequence of the latest pandemic, climate or military force majeures, the existing experience has limited effectiveness in application with regard to sustainability and inclusiveness of entities functioning. The reason is the need for a deeper understanding of the nature of the influence of a wide range of factors that will determine the further methodologically grounded and accountable course of achieving goals. The basis for a more adapted approach to management can be created by holism, which today has gone beyond the scope of a philosophical concept and practical approach in life and social sciences. The main advantage of holistic enterprise management is a generalized systematic vision of all internal and external processes, in particular, based on consideration of the different nature of the impact of the main factors. The study is based on the implications assessment related to data from the Ukrainian environment, due to the simultaneous deployment of several critical macro- and microlevel factors over demography and labor migration correspondingly. Thus, a unique situation has been created that allows testing new developments for the purpose of further improving the principles of enterprise management in other countries.
