Differentiation in housing costs reinforces the concentration of low-income groups in lowrent residential areas through residential location sorting,making the surrounding employment opportunity environment a crucial perspective for assessing urban inclusiveness.Using residential areas as the unit of analysis,this study proposed a multidimensional framework for evaluating the spatial equity of urban employment by jointly capturing disparities between opportunity supply and access across three dimensions: employment opportunity quantity,wage levels,and commuting accessibility.In addition,we compared spatial differentiation among residential area types under rentbased stratification.This study focused on Urumqi,a major city in Northwest China,and integrated multisource geospatial data for 3465 residential areas,including points of interest(POIs),online job postings,and rental data for residential areas.Empirical analyses were conducted using the Gini coefficient,location quotient,and Geographically Weighted Regression(GWR) model.The findings reveal marked disparities in employment access across ring road areas and rent-based groups.In the urban core,low-rent residential areas benefit from relatively favorable commuting conditions;however,the accessible employment opportunities are concentrated in low-wage service sectors.In the peripheral zone,low-rent residential areas face a dual disadvantage of limited nearby employment supply and longer commuting distances.Even when spatial conditions are comparable,low-rent residential areas are systematically disadvantaged relative to non-low-rent residential areas in realized access to both employment opportunity quantity and wage levels.This pattern indicated that capability constraints impede the conversion of spatial resources into effective access.Further analyses highlight housing costs,infrastructure quality,and residential location as key associated factors.The findings underscored the importance of coordinated,targeted policies in affordable housing delivery,the spatial distribution of employment opportunities,and improvements in transport accessibility to promote urban spatial justice. 展开更多

Background:The Indian healthcare sector has undergone significant transformations due to private equity(PE)investments.The influx of capital has facilitated the expansion of infrastructure and improvement in services,particularly in urban and semi-urban areas.However,this transformation raises critical concerns regarding equity in healthcare access,rising health costs,and the potential commercialization of healthcare services.Methods:Employing a critical political economy approach,this study examines the effects of PE investments in Indian healthcare.It integrates theories from Antonio Gramsci,David Harvey and Nancy Fraser to analyze the implications of these investments.The research draws on secondary data from industry reports,government statistics and academic literature to assess the trends,impacts and policy responses related to PE in healthcare.Results:PE investments have led to increased privatization,rising healthcare costs and a focus on profit-driven models.Despite expanding infrastructure,access to quality healthcare remains inequitable,particularly for marginalized and rural populations.The analysis highlights the tension between capital accumulation and public health needs,showing how PE investments prioritize profitability over equity.The commodification of healthcare reflects broader neoliberal policies that undermine public health objectives and exacerbate inequalities.Conclusion:While PE investments drive innovation and expansion,they also pose challenges to affordability and equitable access.Policy interventions are necessary to regulate PE investments and ensure that healthcare remains accessible and equitable for all. 展开更多

In the current era marked by energy shortages,the advancement of nuclear energy stands as an inevitable progression.The reprocessing of spent nuclear fuel plays a crucial role in determining the sustainability of nuclear energy as a viable energy source.Among these processes,the separation and recovery of Pu(Ⅳ)from high-level liquid waste(HLLW)hold paramount significance in terms of safety and strategic implications.Herein,this work focused on the synthesis of two acid-and radiation-resistant pyridine-based sp^(2)c-COFs(COF-IHEP3 and COF-IHEP4),followed by the creation of two pyridine-based ionized sp^(2)c-COFs named COF-IHEP3-CH_(3)NO_(3)and COF-IHEP4-CH3NO3through post-modification.These materials have potential anion exchange capacity for the selective separation of Pu(Ⅳ)in highly acidic conditions.Notably,in 8 mol/L nitric acid solution,COF-IHEP3-CH3NO3demonstrated the capability to eliminate plutonium within 20 min in 98%removal efficiency with a Kdvalue of 2450 m L/g.Experimental and theoretical analysis suggest that the ionized sp^(2)c-COFs exhibit exceptional stability,selectivity,and prevention of secondary contamination towards Pu(Ⅳ)in the presence of multiple ions environments.In short,this work provides an appropriate anion exchange strategy to design ionic sp^(2)c-COFs as a promising platform for Pu(Ⅳ)recovery from HLLW. 展开更多

Ensuring the provision of accessible,affordable,and high-quality public services to all individuals aligns with one of the paramount aims of the United Nations’Sustainable Development Goals(SDGs).In the face of esca lating urbanization and a dwindling rural populace in China,reconstructing rural settlements to enhance public service accessibility has become a fundamental strategy for achieving the SDGs in rural areas.However,few stud ies have examined the optimal methods for rural settlement reconstruction that ensure accessible and equitable public services while considering multiple existing facilities and service provisions.This paper focuses on rural settlement reconstruction in the context of the SDGs,employing an inverted MCLP-CC(maximal coverage loca tion problem for complementary coverage)model to identify optimal rural settlements and a rank-based method for their relocation.Conducted in Changyuan,a county-level city in Henan Province,China,this study observed significant enhancements in both accessibility and equity following rural settlement reconstruction by utilizing the MH3SFCA(modified Huff 3-step floating catchment area)and the spatial Lorenz curve method.Remarkably,these improvements were achieved without the addition of new facilities,with the accessibility increasing by 44.21%,4.97%,and 3.11%;Gini coefficients decreasing by 19.53%,1.64%,and 3.18%;Ricci-Schutz coef-ficients decreasing by 21.09%,2.09%,and 4.33%for educational,medical,and cultural and sports facilities,respectively.It indicated that rural settlement reconstruction can bolster the accessibility and equity of public ser-vices by leveraging existing facilities.This paper provides a new framework for stakeholders to better reconstruct rural settlements and promote sustainable development in rural areas in China. 展开更多

This study examines the causal relationship between financial technology startup venture capital(VC)financing and its deals with domestic credit provided by the banking sector and equity market movement.Despite the rise of alternative finance,such as fintech venture capital(it is the fund that venture capital firms put into young,promising fintech companies so that they can help them expand and scale quickly),which is yet underexplored,borrowers still heavily rely on banks and the stock market for financing.We use panel data from 57 countries from 2010 to 2020 and an advanced econometric method called the cross-sectional autoregressive distributed lag model(CS-ARDL)to determine how the size and number of fintech equity funds dealt with by venture capital firms,banking sector credit,and stock market returns are interrelated at the global level and across regional,income,and economic levels.Our results reveal a cointegrating relationship between fintech venture capital funding and deals with bank loans and equity market returns.However,this relationship varies across the regions studied and between developed and developing economies.Our findings provide crucial guidelines for policymakers to create policies that support balanced financial development by highlighting the global interaction of equity market movements,banking credit,and fintech venture capital investment and lay the groundwork for internationally aligned policies to guarantee the optimal distribution of financial capital and improve economic stability and adaptability by illustrating how these links differ across geographical locations and economic conditions. 展开更多

This editorial critically evaluated the recent study by AlMousa et al,which examined the impact of the Arabic version of the American Academy of Or-thopedic Surgeons Foot and Ankle Outcomes Questionnaire(AAOS-FAOQ)on postoperative quality of life and recovery in Arabic-speaking patients with traumatic foot and ankle injuries.In the context of systemic linguistic exclusion in orthopedic research—where English-language journals dominated most publi-cations and non-English-speaking populations faced dual barriers of trial under-representation and semantic distortions(e.g.,mistranslations of terms like"joint instability"in Arabic)—AlMousa et al's work highlighted the transformative po-tential of culturally adapted methodologies.Their rigorous four-stage adaptation framework validated the Arabic AAOS-FAOQ as a reliable tool,enhancing ecological validity and reducing bias in patient-reported outcomes.However,limitations such as regional specificity(Gulf-centric sampling)and short follow-up periods(4 months)underscored broader challenges in non-English research:Redundant studies,prolonged hospital stays for limited English proficiency patients,and underrepresentation of certain ethnic groups in trials.To dismantle linguistic hegemony,we proposed semantic reconstruction(e.g.,integrating culturally specific indicators like"prayer posture"),dialect-aware neural tran-slation,and World Health Organization led terminology standardization.In line with these proposed solutions,AlMousa et al’s study exemplified how language-sensitive adaptations could bridge equity gaps,while future efforts would need to balance cultural specificity with cross-study comparability through AI-driven multilingual databases and policy mandates for cultural adaptation roadmaps. 展开更多

This study analyzes the spatial accessibility of key services in Caen,France,focusing on how different transport modes(car,bicycle,and public transit)influence access to essential services across the urban and suburban landscape.Indeed,the introduction of traffic restrictions in towns with low emission zones encourages a detailed study,on a fine spatial scale,of the differences in accessibility between different modes of transport,for different services and for different journey times.Using spatial analysis techniques,we examine accessibility patterns in relation to services such as shops,healthcare,education,and tourism,highlighting significant disparities between transport modes.The findings reveal that car travel provides the highest accessibility across all service categories,particularly for healthcare and recreational services,while bicycle and public transit accessibility is more limited,especially in peripheral areas.A Principal Component Analysis(PCA)synthesizes the multimodal accessibility data,and hierarchical clustering identifies distinct patterns of accessibility using different transport modes across the city.The study further explores temporal trends in accessibility,showing how different modes perform over varying travel times.Based on these findings,we propose targeted policy interventions aimed at improving public transit,enhancing cycling infrastructure,decentralizing essential services,and promoting mixed-use urban development.Future research directions include examining socio-economic disparities,the impact of emerging mobility technologies,and the environmental implications of accessibility patterns.This research provides valuable insights for urban planners seeking to improve mobility equity and sustainability in urban areas. 展开更多

During daylight laser polarization sensing of high-level clouds(HLCs),the lidar receiving system generates a signal caused by not only backscattered laser radiation,but also scattered solar radiation,the intensity and polarization of which depends on the Sun’s location.If a cloud contains spatially oriented ice particles,then it becomes anisotropic,that is,the coefficients of directional light scattering of such a cloud depend on the Sun’s zenith and azimuth angles.In this work,the possibility of using the effect of anisotropic scattering of solar radiation on the predictive ability of machine learning algorithms in solving the problem of predicting the HLC backscattering phase matrix(BSPM)was evaluated.The hypothesis that solar radiation scattered on HLCs has no effect on the BSPM elements of such clouds determined with a polarization lidar was tested.The operation of two algorithms for predicting the BSPM elements is evaluated.To train the first one,meteorological data were used as input parameters;for the second algorithm,the azi-muthal and zenith angles of the Sun’s position were added to the meteorological parameters.It is shown that there is no significant improvement in the predictive ability of the algorithm. 展开更多

重整计划清偿方案中包括债转股在内的非现金清偿的名义清偿率约定,引发了实际清偿率或低或高的争议。现有应对方案中诸如赋予债权人清偿方案选择权、明确担保第三人的责任、界定有过错评估机构的法律责任等,虽能部分缓解相关争议,但仍... 重整计划清偿方案中包括债转股在内的非现金清偿的名义清偿率约定,引发了实际清偿率或低或高的争议。现有应对方案中诸如赋予债权人清偿方案选择权、明确担保第三人的责任、界定有过错评估机构的法律责任等,虽能部分缓解相关争议,但仍无法从根源上解决问题。名义全额清偿“名实不符”的核心症结在于重整程序中事前股权评估价格与重整后股权实际价格之间的固有差异,这种差异受评估方法局限性、企业经营不稳定性等因素影响,具有难以完全克服的特性。而在债转股清偿方案中引入对赌条款、可赎回优先股、可转债等股债融合类估值调整工具,可为债务人及其出资人、债权人三方主体提供重新评估股权价值的机会。通过考量股权最终实际价值与重整计划约定的最低清偿比例,可触发双向调整机制:若债权人获得的实际清偿比例低于最低清偿比例,由债务人或者出资人通过现金补偿、股权补偿或股权回购等方式补足差额;反之,则由债权人通过股份让渡、股权赎回等方式返还超额利益,从而实现对重整债权人利益的精准保障。 展开更多
