The cultivation of rural “Local Specialty Products”(“LSPs”) under a green-development framework aligns with the functional positioning of these areas, drives the revitalization of rural industries, and constitutes a fundamental strategy for addressing the unique challenges they face. Although ECAs possess inherent advantages in terms of developing LSPs, they are also confronted by multiple constraints. Accordingly, we propose development objectives that emphasize(a) driving rural industrial prosperity,(b) enhancing the appeal of agricultural heritage, and(c) ensuring inclusive prosperity in the farming communities. In selecting pathways for growth, priority should be given to improving the quality of products, fostering distinctiveness of the technologies, nurturing cultural identities, and upholding the principle of common prosperity. From a policy standpoint, the development of rural LSPs should be recognized as a key lever for advancing the comprehensiveness of rural revitalization in the ECAs. We recommend a set of supportive measures—namely, reinforcing the guidance for spatial planning, integrating the consolidation of factor inputs, and ensuring the robustness of organizational guarantees—to facilitate the high-quality development of LSPs in these areas.展开更多

文摘The circular economy is an innovative concept of both production and consumption.It can reduce wastage,preserve resources,and minimize environmental effects with the help of recycling,recovering resources,and extending the life of products.It works as a pathway to reduce environmental footprints by redesigning production-consumption systems.This review critically examines global circular economy strategies,policy approaches,and persistent barriers that shape environmental footprint outcomes across major sectors.Drawing on a structured narrative review and thematic synthesis,we integrate findings on key circular economy practices,Eco-design,product life extension,reuse,re-manufacturing,recycling,and resource recovery,and assess how they interact with policy instruments such as extended producer responsibility,ecodesign requirements,and waste governance reforms.The analysis highlights that reported benefits(e.g.,reduced material throughput,waste generation,and emissions)are frequently constrained by technological limitations(complex material streams,low-quality recyclate,energy-intensive processing),economic conditions(high upfront costs,weak markets for secondary materials,commodity price volatility),and institutional and behavioral factors(regulatory fragmentation,limited enforcement capacity,low consumer acceptance).We further synthesize methodological challenges in measuring“circularity”and footprint reductions,emphasizing boundary choices,rebound effects,and trade-offs such as increased energy demand or land and water pressures in bio-based substitution.By linking circular economy strategies,barriers,and outcomes in an integrative conceptual framework,the review clarifies why circular transitions often deliver partial gains and identifies leverage points for scaling effective,evidence-based policy and practice.

文摘Purpose:Policies have often,albeit inadvertently,overlooked certain scientific insights,especially in the handling of complex events.This study aims to systematically uncover and evaluate pivotal scientific insights that have been underrepresented in policy documents by leveraging extensive datasets from policy texts and scholarly publications.Design/methodology/approach:This article introduces a research framework aimed at excavating scientific insights that have been overlooked by policy,encompassing four integral parts:data acquisition and preprocessing,the identification of overlooked content through thematic analysis,the discovery of overlooked content via keyword analysis,and a comprehensive analysis and discussion of the overlooked content.Leveraging this framework,the research conducts an in-depth exploration of the scientific content overlooked by policies during the COVID-19 pandemic.Findings:During the COVID-19 pandemic,scientific information in four domains was overlooked by policy:psychological state of the populace,environmental issues,the role of computer technology,and public relations.These findings indicate a systematic underrepresentation of important scientific insights in policy.Research limitations:This study is subject to two key limitations.Firstly,the text analysis method—relying on pre-extracted keywords and thematic structures—may not fully capture the nuanced context and complexity of scientific insights in policy documents.Secondly,the focus on a limited set of case studies restricts the broader applicability of the conclusions across diverse situations.Practical implications:The study introduces a quantitative framework using text analysis to identify overlooked scientific content in policy,bridging the gap between science and policy.It also highlights overlooked scientific information during COVID-19,promoting more evidence-based and robust policies through improved science-policy integration.Originality/value:This paper provides new ideas and methods for excavating scientific information that has been overlooked by policy,further deepens the understanding of the interaction between policy and science during the COVID-19 period,and lays the foundation for the more rational use of scientific information in policy-making.

文摘Sustainable ecological development is key to enhancing the life satisfaction of indigenous populations.However,comprehensive studies on the impact of ecological protection policies on life satisfaction from the perspective of the indigenous populations of national parks are lacking.This study investigated the impact of national park ecological protection policies on the life satisfaction of 496 indigenous households in the Qilian Mountain National Park through a questionnaire survey conducted in 2021,employing an ordered multicategorical logistic regression model.The results showed that overall life satisfaction was high and 17.34%of indigenous populations are very satisfied with their current standard of living,with the highest satisfaction of herding households,followed by nonfarming households,half-farming and half-herding households,and farming households.Livelihood capital components had different impacts on life satisfaction.Policy satisfaction,perceived importance,and participation willingness had different impacts on life satisfaction.Key ecological policy instruments,such as ecological compensation,livelihood skills training,eco-stewardship positions,specialty town development,and natural grassland/forest conservation,significantly enhanced life satisfaction.Therefore,emphasizing the interests of indigenous populations,enhancing their willingness to participate in ecological policies,and improving their nonagricultural and pastoral employment abilities can help to improve overall life satisfaction.
文摘In this paper, we tried to give health services marketing mix and raise patients＇ interest in health services with the contribution to highlighting the possible application mechanisms of different marketing policies on health services in Algeria. Because we see that, health foundations in Algeria like other foundations live in an environment marked with constantly economic, social, politic, and cultural changes. And to respond to change requirements, especially with the appearance of health services market liberation signs, these foundations are obliged to adapt to ensure their existence and development by giving best services to meet the patients＇ needs in order to gain their satisfaction and loyalty. These ones, who became more conscious about the quality of services they are given quantitatively, qualitatively, and timely.
