Adherence to Mediterranean diet and cardiometabolic risk among mountain communities in European Alps

Abstract Background The Mediterranean diet has emerged as a model promoting a better health status, particularly for cardiovascular diseases prevention. Adherence to the Mediterranean diet (AMD) may vary depending on geographical location and sociocultural factors. Mountains and rural communities may experience lower adherence, also depending on food provision-related services availability. Our cross-sectional study aims to investigate the association between AMD and cardiometabolic risk in a cohort of mountain dwellers. As a secondary aim, we will test if services availability may influence health status via AMD. Methods In spring/summer 2023, healthy volunteers from 5 small villages in Italian Alps were enrolled. Dietary habits were investigated by Medi-Lite standardized questionnaire. The waist-to-height ratio (WHtR) was calculated by dividing the waist circumference by height, then used as an anthropometric index for central adiposity and related cardiometabolic risk. Services availability was assessed by network analysis implemented in QGIS. A multilevel logistic regression model, with center as random intercept and adjusted for age, sex, BMI, education and physical activity was used to test the association between AMD and cardiometabolic risk. Ethical approval was provided by University of Turin. Results To date, 142 subjects (59.2% females, 49.9±14.0 y.o.) have been enrolled. Preliminary analyses showed that, as compared to the least adherent group, subjects reporting the highest AMD level (3rd tertile of Medi-Lite scoring) were strongly protected from cardiometabolic risk (OR: 0.07, 95% C.I.: 0.01, 0.67; p = 0.021). A similar trend was observed for the 2nd tertile. Conclusions Our preliminary findings suggest the beneficial role of the Mediterranean diet also in remotely located populations. We plan to investigate how service availability may impact AMD and, indirectly, cardiometabolic health to reinforce the importance of equity in services distribution for Public Health Key messages • Independently of age, sex, BMI, education and physical activity, adherence to the Mediterranean diet can promote cardiometabolic health among rural and mountain communities. • Mediterranean eating pattern can positively influence central adiposity and should be promoted to ensure more effective prevention strategies in mountain dwellers.

Has the Digital Economy Enhanced the Income Distribution Effect Among Industries? Evidence from China

A powerful correlation exists among the advancement of the economy of digital, sustainable economic advancement, and income distribution. The advancement of the digital economy provides a significant motivating factor for sustainable economic development, while sustainable economic development provides a strong guarantee for income distribution, and the improvement of income distribution is also conducive to sustainable economic development. What is the connection between the digital economy and income distribution? This is the focus of this paper and also an important way to clarify the association between the advancement of the digital economy, sustainable economic development, and income distribution. This paper aims to explore whether the advancement of the digital economy has enhanced the effect of income distribution among industries and examine the role of production efficiency and human capital. Through the use of the multidimensional fixed-effect model, this study finds that the development of the digital economy is favorable to enhancing the income distribution effect among industries, and this income distribution enhancement effect is more prominent in large-scale non-state-owned enterprises. In addition, we also find that digital transformation can dramatically improve the total factor productivity of enterprises, thus enhancing the income distribution impact among industries. The promotion of digital transformation can also improve the quality of human capital in enterprises, strengthen the income distribution impact between industries, and reduce the income disparity among industries. The industry income gap measurement method and the industry perspective of income distribution adopted in this paper contribute to the existing literature and will contribute to the development of income distribution equity in the era of the digital economy and also provide a new vision for sustainable economic development from the perspective of income distribution.

Assessing social equity of federal disaster aid distribution: A nationwide analysis.

In this study, we conduct the first comprehensive, nationwide assessment of social equity performance of multiple federal post- and pre-disaster assistance programs that differ in targeted recipients, project types, forms of aid, and funding requirements. We draw on the social equity and distributive justice theory to develop and test a set of hypotheses on the influence of program design and specificity on their aid distributional patterns and equity performance. The analysis uses panel data of about 3000 US counties to examine the relationship between a county's receipt of federal assistance and its recent disaster damage, socioeconomic, demographic, political, local government, and geographic characteristics in a two-stage random effects Tobit model. Expectedly, we find that post-disaster grants are largely driven by recent disaster damage, while damage is simultaneously influenced by local socioeconomic conditions. For all disaster programs, disproportionately more federal aid is allocated to populous counties. For programs geared toward state and local governments and targeting community recovery and mitigation, more aid is received by counties with better socioeconomic conditions. Conversely, for programs targeting individual relief and recovery, more aid is given to counties with lower incomes and greater social vulnerability. Results also indicate that counties located in high-risk regions receive greater outlays. These findings shed light on the varying degrees of social equity of federal disaster assistance programs tied to their cost-share requirement, funding caps, and inherent complexity of application procedures.

Tradeoffs and synergies between social equity and environmental benefits in conservation

Conservation programs worldwide pursue social equity alongside environmental benefits and economic efficiency. When the spatial patterning of human diversity differs from the patterning of biological diversity, conservation planners face complex tradeoffs between social and biological objectives. Here, we quantify how these tradeoffs depend on the correlation between the spatial distributions of social and biological diversity. We used empirical patterns in the commonness and rarity of species to generate simulated landscapes with pre-defined correlations between biological diversity and human social diversity. Our analysis shows how tradeoffs between social equity and environmental benefits are unavoidable when human and biological diversity are negatively correlated. However, when human and biological diversity are strongly positively correlated, then biological and social priorities are congruent. In these settings, well-designed conservation programs may engender positive feedbacks between social equity and ecosystem services, enhancing both. Our analysis focused on distributional equity, but similar dynamics are likely to occur with procedural, recognitional and contextual equity. Given growing evidence that socially equitable conservation programs are more likely to be successful, our findings underscore the importance of carefully assessing the potential for conflicts and synergies between the social and biological goals of conservation programs.

Exploring the equity of distribution of general medical services funding allocations in Wales: a time-series analysis.

Good access to quality primary care in high-income countries can improve population health. Access to primary care is however often not equal among socioeconomic groups; our analysis sought to explore whether funding, a determinant of service supply, is equitably distributed among GP practices in Wales. We sought to explore the relationship between funding and deprivation among GP practices in Wales, to understand the equity of current funding policies. We obtained funding data for general practices in Wales between 2014 and 2022 and explored the equity of distribution using the percentage of practice patients living in the 20% most deprived small areas in Wales. We generated a linear regression model exploring the relationship between practice funding and deprivation, with an interaction term with time in years. Practice funding rose for all practices between 2014 and 2022. Practice deprivation and time in years were both associated with practice funding, with increases in practice deprivation associated with reduced funding allocations, and time being associated with a small increase in funding over the study period. Over the period of analysis of 2004-2022, for every 10% increase in patients living in the most deprived LSOAs, funding per patient decreases on average by 1%. Primary cares in Wales in more deprived areas receive discernibly less funding per patient than those in less deprived areas. Given the potential and likelihood primary care can affect population health outcomes, this underinvestment may be contributing to existing health inequalities and requires urgent further analysis and action.

Equity in the geographical distribution of general practitioners in Iran.

The equitable distribution of workforce is imperative for achieving public health goals. This study was conducted to evaluate the equity of the distribution of general practitioners (GPs) in Iran. In this descriptive and cross-sectional study, data from the Information System of Benefits for Iranians and the Iranian Statistics Center were utilized. The study population encompasses all GPs operating in Iran in 2022. To assess equity in the geographical distribution of physicians, the Gini coefficient and Lorenz curve were calculated using Excel software. Additionally, ArcGIS software was used to create a distribution map. The population of Iran and active GPs in 2022 were 85,874,000 and 67,852 respectively, resulting in an average of 7.9 active GPs per 10,000 people. The provinces of Yazd, Tehran, Mazandaran, and Fars exhibited the highest concentration of active GPs per capita, collectively representing more than 28% of the population and 37% of the active GPs. Fifty percent of the active GPs were women. The Gini coefficients for the provincial and intercity distributions of GPs were 0.08 and 0.2, respectively. The distribution of GPs among provinces and cities was deemed fair and relatively fair, respectively. Iran has a lower ratio of GPs per capita than the European nations. Policymakers should pay more attention to the implementation of appropriate policies with the aim of increasing equity in the geographical distribution of GPs in the country.

The new era of Bitcoin: Profits, progress and potential in the inscription-driven crypto industry

The introduction of the Ordinals Protocol and BRC-20 tokens, featuring the pioneering concept of Inscriptions, signifies a pivotal evolution in the Bitcoin network. Officially launched on 21st January, 2023, this innovation embeds a unique blend of tokenisation and non-fungible attributes directly into Bitcoin’s base layer, akin to engraving precious metals. This paper thoroughly examines the technical underpinnings and market implications of BRC-20 tokens, focusing on the stark contrasts with traditional ERC-20 tokens and initial coin offerings. Unlike ERC-20, Inscriptions integrate seamlessly into Bitcoin’s existing structure, offering a decentralised model that strengthens the principles of a true fair launch in decentralised finance. The study critically assesses the reception within the Bitcoin community, balancing the potential enhancements in Blockchain functionality against concerns regarding foundational principles. Furthermore, it explores the profound implications for stakeholders such as miners, exchanges and developers and evaluates the transformative impact on the cryptocurrency ecosystem at large. Ultimately, this paper elucidates the role of Inscriptions in redefining the trajectory of Bitcoin and shaping the future landscape of Blockchain technologies, emphasising their potential to foster equity and innovation in token distribution.

The abundance and distributional (in)equalities of forageable street tree resources in Lagos Metropolis, Nigeria

AbstractForaging for wild resources links urban citizens to nature and biodiversity while providing resources important for local livelihoods and culture. However, the abundance and distributional (in)equity of forageable urban tree resources have rarely been examined. Consequently, this study assessed the abundance of forageable street trees and their distribution in Lagos metropolis, Nigeria. During a survey of 32 randomly selected wards across 16 local government areas (LGAs) in the metropolis, 4017 street trees from 46 species were enumerated. The LGA with the highest number of street trees was Ikeja, with 818 trees, while Lagos Island had the lowest count, with two trees. This disparity in tree numbers could be attributed to variations in human population density within each LGA. Ninety‐four percent of the street trees surveyed had at least one documented use and 76% had two, making them potentially forageable. However, the most common species had relatively low forageability scores. Only 5.6% of the total street tree population was rated as highly forageable, with a usability score of at least 11 out of 15. The most forageable street trees were fruit trees and non‐native species. The forageable street trees in the LGAs showed a significant disparity in their distribution, as evidenced by a Gini coefficient of 0.81. Overall, richer neighborhoods had a higher street tree abundance, richness, and forageability potential. To meet greening and foraging goals and address the current inequitable distribution, we suggest allocating more funds for greening, particularly in low‐income neighborhoods. Further research should evaluate forageable species from other sites to acquire a detailed understanding of the distribution and abundance of forageable resources in Lagos metropolis.

Distributional equity impacts of automated vehicles: A disaggregated approach

Better understanding of the equity impacts of automated vehicles (AV) is needed to design equitable deployment plans for AV technology. The goal of this study was to develop and demonstrate a modeling framework to support distributional equity assessments of AV systems prior to their wide adoption. This modeling framework takes a disaggregated approach that integrates agent-based simulation, diverse transportation outcomes, and equity analyses. The framework uses individual-level data to capture detailed disparities in transportation outcomes, applies a state-of-the-art multi-agent traffic simulation model (MATSim) to simulate privately-owned and shared AVs simultaneously, and considers distributional equity from multiple perspectives. To test and demonstrate the framework, a case study was conducted for the Tampa Bay region. Five scenarios were considered with different AV market shares and integration strategies based on scenario planning by the U.S. Federal Highway Administration. Results reveal that high AV penetration rates were required for substantial reductions in inequality. The introduction of AVs led to a more even distribution of accessibility, but slightly more uneven distribution of traditional mobility and affordability. Impacts of disparities in outcomes for disadvantaged groups were mixed. These results suggest that AVs will likely perpetuate existing inequity in the transportation system as long as its fundamental structure remains the same as today. Results highlight the importance of planning and design strategies that directly address the distributional impacts to ensure that AV technology is deployed equitably.

Building a resilient health system in Ghana- Lessons from COVID-19 and beyond

The COVID-19 pandemic has exposed weaknesses in the health system in Africa and beyond. There were global health system failures such as the lack of international collaboration, lack of equity in vaccine distribution, poor data accuracy and sharing, and massive global economic losses. Locally, the breakdown and inefficiencies of surveillance networks contributed to the spread of COVID-19. This was worsened by years of neglect and lack of investment in our surveillance systems. The COVID-19 pandemic directly or indirectly affected all spheres of life and affected everyone. Ghana fought the COVID-19 pandemic in the way it knows best. There were some failures but also some very important successes and lessons we learned. This is all garnered towards building a resilient health system capable of resisting the next health event. This editorial focuses on the scope and range of COVID-19 on the health of the population and how it can aid Ghana to build a more resilient healthcare system.

Optimizing restoration: A holistic spatial approach to deliver Nature’s Contributions to People with minimal tradeoffs and maximal equity

Ecosystem restoration is inherently a complex activity with inevitable tradeoffs in environmental and societal outcomes. These tradeoffs can potentially be large when policies and practices are focused on single outcomes versus joint achievement of multiple outcomes. Few studies have assessed the tradeoffs in Nature's Contributions to People (NCP) and the distributional equity of NCP from forest restoration strategies. Here, we optimized a defined forest restoration area across India with systematic conservation planning to assess the tradeoffs between three NCP: i) climate change mitigation NCP, ii) biodiversity value NCP (habitat created for forest-dependent mammals), and iii) societal NCP (human direct use of restored forests for livelihoods, housing construction material, and energy). We show that restoration plans aimed at a single-NCP tend not to deliver other NCP outcomes efficiently. In contrast, integrated spatial forest restoration plans aimed at achievement of multiple outcomes deliver on average 83.3% (43.2 to 100%) of climate change mitigation NCP, 89.9% (63.8 to 100%) of biodiversity value NCP, and 93.9% (64.5 to 100%) of societal NCP delivered by single-objective plans. Integrated plans deliver NCP more evenly across the restoration area when compared to other plans that identify certain regions such as the Western Ghats and north-eastern India. Last, 38 to 41% of the people impacted by integrated spatial plans belong to socioeconomically disadvantaged groups, greater than their overall representation in India's population. Moving ahead, effective policy design and evaluation integrating ecosystem protection and restoration strategies can benefit from the blueprint we provide in this study for India.

A spatial decision support framework for equitable sensor network distribution in the smart city

AbstractThis paper introduces a proof‐of‐concept spatial decision support system (SDSS) that assists decision‐makers to generate equitably distributed sensor networks and evaluate their placement with reference to specific population‐based coverage criteria. Our approach centres equity in infrastructure distribution; we focus on the decision‐making process required to achieve the best possible sensor coverage of the geographical area for selected vulnerable populations and visualise trade‐offs in coverage inherent in infrastructure distribution. The development of the tool brings together expertise from quantitative geography, urban planning, data science and software engineering, and its technical development is underpinned and shaped by interviews with decision‐makers and their iterative feedback. Through this, we ask: how can decision support tools help with the work of building equitable infrastructure? As well as a technical application, our approach develops a conceptual framework for evaluating sensor network purpose and distribution before actual placement. The unique combination of distribution algorithms, user interface and decision‐maker input, developed by an interdisciplinary team, offers a novel approach to sensor network conceptualisation and generation. Our research contributes to the understanding of the distribution of essential infrastructure and can be repurposed for any sensor type and geographical location to promote equity in infrastructure distribution.

The effect of public tolerance towards corruptive behaviour on healthcare efficiency and equity – The case of the UK's COVID-19 vaccination programme

Over the past four years, the COVID-19 pandemic has caused significant uncertainty, suffering, and economic disruption on a global scale. In response, governments have been under pressure to ensure equitable vaccine access while meeting vaccination targets quickly. These challenging circumstances created opportunities for nepotism and bribery, increasing attention to corruption risks associated with the pandemic response. This study investigates the relationship between public attitudes towards corruptive behaviour and the efficiency and equity of the UK's COVID-19 vaccination programme. It integrates primary data on public tolerance towards corruptive behaviour with secondary data on the efficiency of the vaccination program at the local authority level in England and Scotland. Employing a survival analysis approach, we estimate Cox Proportional Hazards Models to examine the time required to reach vaccination targets. Our findings suggest moderate tolerance towards corruptive behaviour among the British public, with 28% of survey participants considering monetary bribery and 34% considering nepotism/favouritism as acceptable means to secure early vaccination access. Notably, while public tolerance towards corruptive behaviour generally had a negative impact on the efficiency of the local rollout of the vaccination programme, it appeared to have accelerated its rollout in politically aligned local authorities governed by the Conservative and Unionist Party. However, this increase in efficiency seems to have come at the cost of reduced equity in vaccine distribution. These findings suggest a trade-off between efficiency and equity in vaccine distribution during public health crises, emphasising the need for balanced health policies that ensure fair and effective distribution of vaccines in the future.

Filling the blindspots: Assessing distributive equity in fund allocation of Florida's local housing program for disaster recovery

Despite the role of local assistance in addressing households' disaster recovery needs, few studies have examined the role of localized programs in filling the gaps that might exist in federal programs. To address the question of whether local recovery funds distribute resources to socially vulnerable neighborhoods and how local assistance fits into the broader federal disaster assistance landscape, we take Florida's State Housing Initiatives Partnership (SHIP) program as a case study. The SHIP program can help fill neighborhood-level gaps left by the Federal Emergency Management Agency's (FEMA) Individual Assistance program by aiding neighborhoods with the higher proportions of 1) those who did not receive federal assistance or 2) those who had residual damages not fully covered by federal assistance. The study finds that SHIP funds typically flow into socially vulnerable neighborhoods with a higher proportion of Black and Hispanic residents, even without specific social or racial equity measures built into program regulations. The study highlights the importance of balancing the consistency of fundamental rules and having flexibility in distributing funds.

The complementary role of distributive and criminal equity

AbstractWe conduct a theoretical analysis to explore how the distribution of wealth in society impacts the social costs of crime and law enforcement. We show that a reduction in inequality reduces these costs when enforcement and nonmonetary punishment are equitable, that is, they do not discriminate among offenders based on their wealth. However, when enforcement or nonmonetary punishment is discriminatory, a reduction in inequality may increase the social costs of crime and law enforcement, in particular when it occurs among poorer individuals. Thus, there is a complementarity between equity in criminal justice and distributional equity.

A new two-stage emergency material distribution framework for urban rainstorm and flood disasters to promote the SDGs

Under the coupled effects of climate change and urbanization, urban rainstorm and flood has become more frequent and intense. The effect of the flood disasters emergency response has a direct impact on the success or failure of the rescue. Emergency material distribution is one of the most critical steps in the emergency response phase and is crucial to achieve the Sustainable Development Goals (SDGs). This study proposes a two-stage emergency material distribution framework for urban rainstorm and flood disasters. The entropy weight method and technique for order preference by similarity to ideal solution (EWM-TOPSIS) was adopted to incorporate the difference in relief-demand urgency into the emergency material distribution principle. The mathematical model was established by minimizing emergency travel time, inequity and social costs (logistic costs and deprivation costs) as objective functions. The gamultiobj algorithm was used to solve the model. The proposed framework is further applied in Xi'an city of China. The results showed that the affected sites were categorized into disaster risk levels I, II and III. The Pareto solution set was obtained by optimizing each conflicting objective. The emergency material distribution plan was selected from the Pareto solution set based on the actual situation. In the plan, the flood disasters emergency travel time totaled 6.48 h, the inequity totaled 3.69, and the total social costs reached 226,584 CNY. The proposed framework is more consistent with the needs of the actual rescue by comparing the four models generated plans. Decision-makers should not only consider minimizing dispatch time and social costs, but also the trade-off between equity and prioritization of distribution. This study helps to provide new ideas for sustainable urban development and emergency management. Urban rainstorm and flood disasters change with the changing environment dynamically, and it is difficult to collect dynamic disaster information on the affected sites. Thus our further study will focus on improving the prediction accuracy of dynamic urban rainstorm and flood disasters.

A framework for assessing the blue equity of social-ocean systems in marine governance transformation

The equitable utilization of marine resources and the maintenance of healthy and sustainable marine ecosystems are essential to advancing the United Nations Sustainable Development Goals (SDGs) and promoting the well-being of all humanity. In this paper, we propose a Blue Equity Assessment Framework, which is based on a systematic literature review approach and takes into account the characteristics of Social-Ocean Systems (SOSs). The framework consists of Distributional Equity, Procedural Equity, Recognitional Equity, and Contextual Equity. The aim of this framework is to conduct equity analyses of policies or behaviors within SOSs in order to assess whether blue equity is explicitly implemented and practiced in these societal norms and policy mechanisms. The assessment framework reveals that blue equity has a positive synergy for the majority of the SDGs. This synergy is analyzed in terms of its influence on the assessment dimensions of distributional justice, procedural justice, recognitional justice, and contextual justice. The findings aim to enhance societal understanding of blue equity issues, thereby guiding policymakers in the prioritization of blue equity in the development and utilization of marine resources and in the transformation of global ocean governance.

Perceived equity in marine management and conservation: Exploring gender intersectionality in Fiji

Ensuring equitable decision-making and distribution of costs and benefits in conservation and natural resource management is morally right and instrumental to achieving positive social and ecological outcomes. Understanding perceived equity is key; equity is subjective, context-dependent and has implications for legitimacy, cooperation and wellbeing. Since gender, in combination with other social characteristics, influences how people benefit or participate in management, examining perceived fairness from an intersectional perspective is crucial. However, few studies have examined people's perceptions of equity and how those perceptions are related to intersecting identities. Using data from ten villages in Fiji, we assess how perceptions of distributional and procedural equity differ by gender and the intersection between gender and other social identity characteristics (migrant status, age, education, marital status and wealth). We found that the majority of respondents identified the broader community as benefiting the most from management, while women were the most negatively affected. Overall, respondents' perceptions of distributional and procedural fairness were high regardless of gender. The intersection between gender and other social identity characteristics was not significantly related to perceived fairness, except in relation to migrant status; migrant men were less likely to perceive distributional fairness. Our study provides new insights into patterns of perceived (un)fairness in marine management and conservation. It reveals a discrepancy between conservation costs (women are seen as more negatively affected by conservation) and fairness perceptions (women are not more likely to perceive unfairness). Our findings can inform conservation theory and practice aimed at fostering equity in conservation and management.
