RESUMO
Digitalisation and technological developments are profoundly changing the socioeconomic structure of society and people's lifestyles, which may have a significant impact on the distribution of income among different groups of people. This study conducted a quantitative investigation into the impact of the digital economy on income inequality based on the skill bias theory. First, empirical model analysis showed that digital economy has a linear dampening effect on income inequality and that there is no non-linear relationship. Then, the study analyzed the mechanisms underlying this relationship, which revealed that mining and remittances suppress income inequality in the presence of digital economy, while government spending promotes income inequality. Finally, heterogeneity analysis indicated that the suppressive impact of digital economy on income inequality in capitalist countries is stronger than in ex-communist countries. These findings will not only help to achieve social equity, but also provide a strategic direction for economic development to make the dividends of the digital economy more inclusive.
RESUMO
This study extended the theory of planned behaviour (TPB) and applied it to analyse influencing factors of food waste separation intention (FSI) among households in central Vietnam. Partial least squares structural equation modelling (PLS-SEM) was employed to analyse the data. The heterogeneity of factors contributing to FSI in cities of three levels was examined using multi-group analysis (MGA). The results indicate that attitudes, subjective norms (SN), perceived behavioural control (PBC), awareness of benefit (AB), information publicity (IP), facility availability (FA), and trust significantly affected FSI of households. MGA results indicated the heterogeneity of impacts of PBC and attitude on FSI of households among three municipal levels. The results will serve as basic data for waste officers, solid-waste management project leaders, non-governmental organisations (NGOs), and other related stakeholders to lay the foundation of food waste management planning in terms of regional scale and local scale. This study will also aid the creation of a circular economy by providing a scientific base for enhancing food waste separation at source in central Vietnam.
RESUMO
BACKGROUND: 'Textbook Outcome' (TO) represents an effort to define a standardized, composite quality benchmark based on intraoperative and postoperative endpoints. This study aimed to assess the applicability of TO as an outcome measure following liver resection for hepatic neoplasms from a low- to middle-income economy and determine its impact on long-term survival. Based on identified perioperative predictors, we developed and validated a nomogram-based scoring and risk stratification system. METHODS: We retrospectively analyzed patients undergoing curative resections for hepatic neoplasms between 2012 and 2023. Rates of TO were assessed over time and factors associated with achieving a TO were evaluated. Using stepwise regression, a prediction nomogram for achieving TO was established based on perioperative risk factors. RESULTS: Of the 1018 consecutive patients who underwent liver resections, a TO was achieved in 64.9% (661/1018). The factor most responsible for not achieving TO was significant post-hepatectomy liver failure (22%). Realization of TO was independently associated with improved overall and disease-free survival. On logistic regression, American Society of Anesthesiologists score of 2 (p = 0.0002), perihilar cholangiocarcinoma (p = 0.011), major hepatectomy (p = 0.0006), blood loss >1500 mL (p = 0.007), and presence of lymphovascular emboli on pathology (p = 0.026) were associated with the non-realization of TO. These independent risk factors were integrated into a nomogram prediction model with the predictive efficiency for TO (area under the curve 75.21%, 95% confidence interval 70.69-79.72%). CONCLUSION: TO is a realizable outcome measure and should be adopted. We recommend the use of the nomogram proposed as a convenient tool for patient selection and prognosticating outcomes following hepatectomy.
RESUMO
The COVID-19 pandemic led many countries to consider reforms to their economic policies, in part to better deal with global warming, mass population migration and displacements, and worsening global inequalities. Some health progressive changes have been made, but the world still confronts the contradiction between economic growth and the need to reduce aggregate global consumption. Well-being economies based on valuing human and planetary health have been proposed as a viable option, with more appeal than concepts such as degrowth or postgrowth economics. Some governments are moving in a "well-being economy" direction, but are they moving far and fast enough? What are the policy actions governments must take, and how will they overcome powerful interests opposed to any economic changes that might challenge their privileges? The idea of well-being economies resonates strongly with most cultures; and therein lies its civil society activist potential.

BACKGROUND: Much has been said by actors from different fields and perspectives about the manifold changes in world affairs triggered by the COVID-19 pandemic. In this context, it is to be expected that there will be impacts on long-standing partnerships such as the one between the European Union and the Community of Latin American and Caribbean Countries. However, few studies have demonstrated these impacts, either empirically, by uncovering their specificities or from a historical perspective, to allow for a reasonable methodological comparison of the patterns used to define the partnership and that have changed or have been affected in some way by the pandemic. RESULTS: Through an in-depth qualitative assessment of primary and secondary sources, this article contributes to this research gap. It analyzes the patterns and changes or impacts in light of two strands of behavior that can make sense of EU-CELAC health cooperation-revisionist or reformist. The findings show an economy-driven health agenda as a new pattern of cooperation, which derives from EU reformist behavior after the pandemic. CONCLUSIONS: The EU power to enforce its priorities in the context of health cooperation with CELAC is the main factor that will define how (and not just which) competing interests and capacities will be accommodated. The relevance of the study to the fields of global governance for health, interregional health cooperation and EU foreign policy is threefold. It shows us i.how two more international regimes are easily intertwined with health-trade and intellectual property-with the potential to deepen asymmetries and divergences even between long-standing strategic partners; ii.contrary to the idea that reformist behaviors are only adopted by actors who are dissatisfied with the status quo, the study shows us that the reformist actor can also be the one who has more material power and influence and who nevertheless challenges the success of cooperation in the name of new priorities and the means to achieve them; and iii.how the EU will find it difficult to operationalize its new priorities internally, among states and private actors, and with those of CELAC, given the history of intense disputes over health-related economic aspects.

RESUMO
An interview-based questionnaire survey was done in 2021 to assess the socio-economic conditions, farming practices adopted, and problems faced by fish farmers and to analyze the cost and benefits of fish farming in the Fish super zone area of Pachrauta Municipality, Bara district. A simple random sampling technique was used to select 60 respondents for the study and the information collected was analyzed and processed by MS-Excel and SPSS. The majority of respondents were male, belonged to the age group of 25-36 years, and had a secondary level of school education. The mean total land holding size was found to be 3.65 ± 2.57 bigha with a total pond area of 1.38 ± 1.08 bigha and a small minority (18 %) practiced contract farming. Most of the farmers were found to have experience of 6-11 years (40 %). The farming system was polyculture and mostly Intensive (60 %). While the use of modern equipment was low (25 %), the majority of farmers (>90 %) practiced regular drying and liming of ponds. Mid-April to Mid-July was the most preferred time of stocking and the big fraction of feed used was locally prepared (70 %). Fertilizer use and Multiple harvesting were also common. Fish farming in the study area was found to fetch an average annual income of 0.95 million NRs. The major problems faced by farmers were Expensive feed (0.67), Lack of quality seeds (0.60), and Lack of proper marketing channels (0.55). Despite the constraints, Economic analysis revealed fish production in the study area as a profitable business with a BC ratio of 2.20 and a high gross margin value (Rs. 1330341.6 per hectare).
RESUMO
OBJECTIVE: To enhance Making Every Contact Count (MECC, an opportunistic approach to health promotion), training in the Third and Social Economy (TSE, all groups and organisations primarily working towards social justice, outside of the government or household) by examining the degree to which the behavioural content of MECC training tackled significant factors influencing MECC delivery. METHODS AND MEASURES: A strategic behavioural analysis design. Semi-structured interviews with service providers (n = 15) and users (n = 5) were coded for barriers and facilitators of MECC delivery using the Theoretical Domains Framework (TDF). Existing MECC training was coded for behaviour change techniques (BCTs) and intervention functions (IFs). The degree to which BCTs and IFs addressed the key TDF domains of influences on MECC delivery in the TSE were examined using prespecified tools. RESULTS: Seven key TDF domains of influences in MECC delivery were identified. Overall, only 9/31 linked BCTs were utilised within MECC training, with percentage utilisation of relevant BCTs for each domain ranging from 0% to 66.7%. Training adequately addressed 2/7 key domains. CONCLUSION: The TSE and healthcare share many common key TDF domains, although there are differences in how each are relevant. Limitations and recommendations for MECC training are discussed.
RESUMO
The Tetrahedron approach is a new environmental tool adapted to assess the sustainability of anthropogenic processes. This tool is based on a four-step methodology that includes (a) the identification of critical parameters, (b) evaluation through the Tetrahedron Parameter Global Evaluator, (c) construction of a tetrahedron diagram based on the final scores and (d) quantitative estimation of the global sustainability. The Tetrahedron incorporates various aspects of sustainability, including economic, social and environmental factors, and provides a comprehensive framework for evaluating the impact of human activities. This article presents the methodology and application of the Tetrahedron in determining the sustainability of five case studies: CO2 capture, unconventional methanol production, the Solvay process, CO2-alcoholic fermentation process strategy and the CO2-Rumen fermentation process strategy. The results demonstrate the Tetrahedron as an effective and reliable tool to quantify the sustainability of anthropogenic processes and to promote sustainable practices across various industries and sectors. The Tetrahedron offers several advantages over other environmental assessment tools, including holistic approach, simplicity and flexibility.
RESUMO
Carers were disproportionately harmed in the COVID-19 pandemic. Despite facing an increased risk of contracting the virus, they continued in frontline roles in care services and acted as "shock absorbers" for their families and communities. In this article, we apply an intersectional lens to examine care work and the structural factors disadvantaging carers during COVID-19 through a comparative case study analysis of 16 low-, middle-, and high-income countries. Data on each country was collected through a qualitative framework during 2021-2022. We found that while carers everywhere were predominantly women with low incomes and precarious employment, other factors were at play in shaping their experiences. Moreover, government responses to mitigate the direct impact of the pandemic have created local and global disparities affecting those working in this sector. Our findings reveal how oppressive social structures such as race, class, caste, and migration status converged in contextually specific ways to shape the gendered nature of care within and between different countries. We call for a better understanding of the multiple axes of inequalities experienced by carers to inform crisis mitigations, coupled with long-term strategies to address social inequities in the care economy and to promote gender equality.
RESUMO
Despite the global focus on sustainability, transitioning from linear to circular production systems is slow in the mining sector of most developing economies like Namibia. However, mining plays a crucial role in supporting the livelihoods of local communities. Furthermore, existing literature indicates that the potential for regenerative production systems using the remanufacture and recycle approach remains low and limited within the mining and developing economies. Institutional theory can help reveal the reasons for the slow take-up of the regenerative circular economy models in mining. This study uses a unique dataset of 40 semi-structured interviews with key players in the mining sector of Namibia to understand the current phase of circular economy adoption and the role played by institutional pressures in the process of institutional isomorphism, when companies would display a similar level of practices within a shared institutional environment. The findings reveal: (1) 72.5% of participants believe that Namibian mines are adoption-decision phase-a beginning stage of circular economy adoption; (2) companies are reliant on heavy government participation through policy/legislation and tax incentives is recommended; (3) the ranked order-coercive, normative, and mimetic pressures-describes their significance among key actors, for the successful adoption; and (4) proactive implementation and a mindset shift towards circularity is needed to meet emerging expectations on social and environmental concerns in mining.
RESUMO
Upcycling waste polyethylene terephthalate (PET) bottles has attracted intensive research interests. This simultaneously alleviates plastic pollution and achieves a waste-to-resource strategy. Waste PET water bottles were used to fabricate value-added activated carbon (AC) electrodes for capacitive deionization (CDI). The KOH activation temperature (greater than 700 °C) prominently affected the physi-chemical properties and desalination performance of PET-derived activated carbons (PET-AC). Profiting from a large Brunauer-Emmet-Teller specific surface area (1448 m2 g-1) with a good mesoporous structure (the ratio of the mesopore volume to the total pore volume was 41.3%), PET-AC-1000 (activated at 1000 °C) possessed a huge specific capacitance of 108 F g-1 for capacitive ion storage. Moreover, when utilized as the electrode material in single-pass CDI, PET-AC-1000 exhibited a maximum electrosorption capacity of 10.82 ± 0.11 mg g-1 and a low level of energy consumption (0.07 kWh mol-1), associated with good electrochemical charging-discharging cyclic stability. The results provide a promising facile approach to tackle the challenge of plastic pollution and promote the advancement of electrode materials for economic affordable and energy-efficient electrochemical desalination process, which meets the United Nations (UN) sustainable development goals (SDGs).
RESUMO
This critical review considers the status of 21st-century epidemiological theories of disease distribution, updating to 2024 prior analyses published up through 2014, and discusses the implications of these theories for research, practice, and pedagogy. Three key trends stand out: (a) the continued dominance of individualistic biomedical and lifestyle theories; (b) growth and elaboration of social epidemiological alternatives; and (c) the ongoing inattention to epidemiologic theories of disease distribution in the training of epidemiologists and public health professionals and in current efforts to improve the rigor of epidemiological research and causal inference. In a context of growing global political polarization, climate crisis, broader environmental and ecological crises, and stubbornly persistent health inequities within and between nations, producing actionable knowledge relevant to improving the people's health and advancing health justice will require much greater engagement with social epidemiologic theories of disease distribution in research, pedagogy, and practice. At issue is critically engaging with the embodied truths manifested in the stories bodies tell in population patterns of health, disease, and well-being.

An innovative circular economy (CE) system was implemented at the wastewater treatment plant (WWTP) in Brunswick. The performance of the CE system was evaluated for 4 years: the thermal pressure hydrolysis enhanced the methane production by 18% and increased the digestate dewaterability by 14%. Refractory COD formed in thermal hydrolysis and increased the COD concentration in the WWTP effluent by 4 mg L-1 while still complying with the legal threshold. Struvite production reached high phosphorus recovery rates of >80% with a Mg:P molar ratio ≥0.8. Nitrogen was successfully recovered as ammonium sulfate with high recovery rates of 85-97%. The chemical analyses of secondary fertilizers showed a low pollutant content, posing low risks to soil and groundwater ecosystems. The total carbon footprint of the WWTP decreased due to enhanced biogas production, the recovery of renewable fertilizers and a further reduction of nitrous oxide emissions. Using green energy will be crucial to reach carbon neutrality for the entire WWTP.

Biogas production from cattle manure, pivotal for sustainable waste and energy management, encounters challenges from its low digestibility linked to lignocellulosic structures. This study investigates biogas efficiency enhancement through anaerobic digestion coupled with solar thermal (ST) pretreatment and digestate application in Napier grass cultivation (STAD-G). ST pretreatment at 40-60 °C for 20 h markedly increases methane yield, validated by pilot-scale trials that exhibited a 3.9-fold surge in methane production, attributed to improved acidification. Untreated manure's structure, however, impedes acidification, slowing methanogenesis as shown by lower volatile fatty acid concentration in effluents. In addition, utilizing digestate as soil conditioner notably improves grass yield (19.3 ± 0.8 ton dry/ha/year) and protein content, akin to urea fertilizer. Furthermore, the STAD-G system incurs higher upfront costs, it yields superior biogas efficiency and enhanced long-term financial returns. This integrated approach, by boosting economic and environmental sustainability, advocates for ST pretreatment as a key strategy in advancing sustainable agriculture and energy solutions.
RESUMO
The transition to a Circular Economy (CE) is rapidly gaining ground across countries and industries. It is the means of achieving more sustainable development by adopting innovative environmentally friendly strategies and saving primary resources. There are several studies indicating the increasing public and corporate interest in the CE but still remain limited in terms of the multitude and utilization of social media data. This work aims to shed light on the most common topics discussed on the YouTube platform, related to the CE. For this reason, we selected 17 videos including the term "Circular Economy" since these have been the most relevant with a sufficient number of comments and views. The model identified two main topics referring to "Sustainable industry and environmental responsibility" and "Circular Economy and resource management" which is a strong indicator of the people's interest in the utilization of resources alongside industrial and corporate activities. The two-topic configuration presented the highest coherence score; however, five and ten-topic configurations have been deployed since there was no extreme differentiation in the model's performance, which could provide more detailed insights. This work's innovation lies in utilizing Machine Learning techniques and social media data to unravel CE's debates.
RESUMO
The modern era of running shoes began in the 1960s with the introduction of simple polymer midsole foams, and it ended in the late 2010s with the introduction of advanced footwear technology (AFT). AFT is characterized by highly compliant, resilient, and lightweight foams with embedded, rigid, longitudinal architecture. This footwear complex improves a runner's efficiency, and it introduced a step change in running performance. Purpose: This review serves to examine the current state of knowledge around AFT-what it is and what we know about its ingredients, what benefits it confers to runners, and what may or may not mediate that benefit. We also discuss the emerging science around AFT being introduced to track-racing spikes and how it is currently regulated in sporting contexts. Conclusions: AFT has changed running as a sport. The construction of AFT is grossly understood, but the nature of the interacting elements is not. The magnitude of the enhancement of a runner's economy and performance has been characterized and modeled, but the nuanced factors that mediate those responses have not. With these knowns and unknowns, we conclude the review by providing a collection of best practices for footwear researchers, advice for runners interested in AFT, and a list of pertinent items for further investigation.
RESUMO
This paper describes the work-related information collected in several important U.S. national health and behavior surveys, to highlight data gaps that prevent identifying responses by vulnerable workers in the gig economy, with emphasis on the growing digital platform sector of the work force. The national information systems used to understand health status and health behaviors, including drug use, rely on outdated census categories for self-employed workers. This paper describes the importance of understanding the needs of this growing part of the labor sector and describes how some of the most well-known and utilized national surveys fail to meet this need. For the agencies conducting national health and behavior surveys, we propose revisions to the categories used to classify type of worker and recommend adoption of a new Worker-Employer Relationship Classification model.
RESUMO
In this study, the generation of domestic waste electrical and electronic equipment (WEEE) and waste printed circuit board (WPCB) were estimated, from 2015 to 2030. Based on the number of EEE put on the Brazilian market, the possession rate in the Brazilian households and obsolescence amounts of five EEE types were estimated using time series. The results show that, between 2015 and 2030, the quantity of WEEE generated per year will increase from 131.87 kt to 195.22 kt. In this period, WPCB generation will stay around 10% of WEEE generation. Additionally, this study shows that the urban mining potential of the materials recoverable from WPCB can be an important revenue source, with environmental benefits deriving from energy savings and a reduction in CO2 emissions. The results of this study provide a quantitative basis that may help decision makers develop strategic policies for WEEE management, considering material circularity.
