Travel time variability (TTV) is a crucial indicator of transportation network performance, assessing travel time reliability and delays. This study investigates TTV metrics within the context of shared mobility using probe data from transportation network companies (TNCs) in Chicago, Los Angeles, and Dallas–Fort Worth. Eight reliability metrics are analyzed and compared for each origin–destination (OD) pair in the network, including standard deviation (SD), the Planning Time Index (PTI), the Travel Time Index (TTI), the Buffer Index (BI), On-time Measures PR (alpha), and the Misery Index (MI), to evaluate their effectiveness in clustering OD pairs using K-means clustering. The findings confirm that SD, PTI, and MI are particularly effective in measuring travel time reliability and clustering within urban systems. This study identifies the most unbalanced supply–demand OD pairs/regions in each city, noting that low/medium-SD clusters around metropolitan airports indicate stable travel times even in high-demand zones, while high-SD clusters in downtown areas reveal significant traffic demands and unreliability. These patterns become more pronounced in study areas with multiple city centers. This study highlights the need for targeted strategies to enhance travel time reliability, particularly in regions like Dallas–Fort Worth, where public transportation alternatives are limited.
旅行时间变异性（TTV）是交通网络性能的一个重要指标，可评估旅行时间的可靠性和延误情况。本研究利用芝加哥、洛杉矶和达拉斯-沃斯堡的运输网络公司（TNCs）的探测数据，研究了共享交通背景下的 TTV 指标。研究分析并比较了网络中每个出发地-目的地（OD）对的八个可靠性指标，包括标准偏差（SD）、计划时间指数（PTI）、旅行时间指数（TTI）、缓冲指数（BI）、准时措施 PR（alpha）和痛苦指数（MI），以评估它们在使用 K-means 聚类对 OD 对进行聚类时的有效性。研究结果证实，SD、PTI 和 MI 在测量城市系统内的旅行时间可靠性和聚类方面尤为有效。本研究确定了每个城市中供需最不平衡的 OD 对/区域，注意到大都市机场周围的低/中标度聚类表明即使在高需求区也有稳定的旅行时间，而市中心区的高标度聚类则揭示了显著的交通需求和不可靠性。在有多个城市中心的研究区域，这些模式变得更加明显。这项研究强调，需要采取有针对性的策略来提高旅行时间的可靠性，尤其是在达拉斯-沃斯堡这样公共交通选择有限的地区。

The monitoring of carbon emissions is increasingly becoming a sustainability issue worldwide. Despite being largely unnoticed, the toxic gas carbon monoxide (CO) is ubiquitous in mechanized tunnel driving, but the individual sources, release and enrichment mechanisms are often unknown. In this study, the generation of CO from organic matter containing sedimentary rocks was investigated during mechanized tunnel driving and by reacting claystone and sandstone with 10 mM NaCl solutions for 2 months at 70 °C and 140 °C. The mineralogical and geochemical evolution of the solids and fluids was assessed by CO measurements and the XRD, DTA, TOC, IC and ICP-OES methods. The CO concentration in the atmosphere reached up to 1920 ppm (100 ppm on average) during tunnel driving, which is more than three times higher than the legal daily average dose for tunnellers, thus requiring occupational safety operations. Mineral-specific dissolution processes and the rapid decomposition of labile organic matter upon thermal alteration contributed to the liberation of CO and also carbon dioxide (CO2) from the host rocks. In mechanized tunnel driving, frictional heat and ‘cold’ combustion with temperatures reaching 50–70 °C at the drill head is an important mechanism for increased CO and CO2 generation, especially during drilling in sedimentary rocks containing significant amounts of OM and when the ventilation of the tunnel atmosphere and air mixing are limited. Under such conditions, human health damage due to CO exposure (HHDCO) can be 30 times higher compared to tunnel outlets, where CO is emitted from traffic.
碳排放监测正日益成为全球范围内的一个可持续发展问题。一氧化碳（CO）这种有毒气体在隧道机械化行驶过程中无处不在，但其来源、释放和富集机制却往往不为人知。本研究调查了在隧道机械化掘进过程中，通过在 70 °C 和 140 °C 温度下将粘土岩和砂岩与 10 mM NaCl 溶液反应 2 个月，从含有有机物的沉积岩中产生一氧化碳的情况。通过 CO 测量和 XRD、DTA、TOC、IC 和 ICP-OES 方法评估了固体和流体的矿物学和地球化学演变。在隧道开挖过程中，大气中的一氧化碳浓度高达 1920 ppm（平均 100 ppm），比隧道工人的法定日平均剂量高出三倍多，因此需要进行职业安全操作。特定矿物的溶解过程和热蚀作用下易变有机物的快速分解，导致二氧化碳和二氧化碳（CO2）从母岩中释放出来。在机械化隧道掘进过程中，摩擦热和 "冷 "燃烧（钻头温度达到 50-70 °C）是一氧化碳和二氧化碳生成增加的重要机制，尤其是在含有大量有机物的沉积岩中钻进时，以及在隧道大气通风和空气混合受到限制的情况下。在这种条件下，与隧道出口相比，因接触一氧化碳（HHDCO）而对人体健康造成的损害可能要高出 30 倍，因为隧道出口处的一氧化碳是由交通排放的。

Although corporate social responsibility (CSR) can be examined from the point of view of the fundamental philosophy of business and society, many companies focus solely on profit. The main goal of this research is the investigation of the relationship between CSR and organizational financial performance, and the role of customer satisfaction in the proposed relationship. To investigate the proposed relationships, PLS–SEM analysis was performed using the statistical software Smart PLS. The sample used for this study consists of 165 large companies that operate in the Republic of Serbia, each with more than 250 employees (large organizations). The obtained results showed that in companies in Serbia, there is a positive and statistically significant relationship between CSR and customer satisfaction and a positive but statistically insignificant relationship between CSR and financial performance. Regarding the mediating role of customer satisfaction in explaining the relationship between CSR and financial performance, a positive full mediation relationship was found. Theoretical and managerial implications are also provided.

Loss of biodiversity and natural degradation are vital issues that have significant impacts on society and economy. Businesses, investors, and regulators have focused on corporate efforts to support biodiversity and nature-positive activities. This review provides a comprehensive overview of the importance of biodiversity for businesses, its materiality, and the roles of mandatory and nonmandatory regulations in corporate environmental reporting and sustainability disclosure frameworks. It also discusses descriptive information on the evolution of sustainability frameworks by comparing the most prominent sustainability frameworks, with a key focus on the materiality approach and biodiversity-related disclosure recommendations. Furthermore, we provide recommendations for more holistic approaches to improve future sustainability frameworks focusing on the impact of biodiversity. Additionally, we demonstrate the necessity for greater focus on the decision-making paradigm. Further research to measure the impact of biodiversity and innovative trends in sustainability reporting is required to better reflect nature-positive outcomes in corporate sector businesses.

This research aims to verify the effect of outdoor green teaching experiences on school affective qualities, perceived restorativeness, school climate, and global well-being in a sample of school teachers. A comparison was conducted between teachers who work mainly indoors and those who frequently run school activities outdoors in green spaces. A sample of kindergarten and primary school teachers working in different Italian regions (n = 209) filled in an online questionnaire including the Satisfaction with Life Scale (SWLS), the Perceived Restorativeness Scale (PRS-11), the Scale of Affective Qualities of Place, and the Revised School Level Environment Questionnaire (RSLEQ). Zero-order correlations, preliminary descriptive analyses of variance (ANOVAs) to compare teachers conducting Outdoor Education (vs. teachers conducting only or almost always indoor education), and structural equation modeling (SEM) were carried out on the measured variables. Results from ANOVAs evidenced that teachers conducting outdoor green education show higher levels of perceived affective qualities and restorativeness than teachers working mainly indoors. The model tested through SEM analysis showed that positive affective qualities attributed to the school are associated with higher levels of restorativeness and this, in turn, is linked to a more positive perception of social relationships at school, which increases life satisfaction. Overall, these outcomes support previous research demonstrating the beneficial psychological effects of nature experiences, also in the school environment.
本研究旨在验证户外绿色教学体验对学校教师样本的学校情感品质、感知恢复性、学校氛围和全球幸福感的影响。研究对主要在室内工作的教师和经常在户外绿地开展学校活动的教师进行了比较。在意大利不同地区工作的幼儿园和小学教师样本（n = 209）填写了一份在线问卷，其中包括生活满意度量表（SWLS）、感知恢复性量表（PRS-11）、场所情感质量量表和修订版学校环境问卷（RSLEQ）。对测量变量进行了零阶相关分析、初步描述性方差分析（ANOVA）以比较开展户外教育的教师（与只开展或几乎总是开展室内教育的教师），以及结构方程模型（SEM）。方差分析结果表明，与主要在室内工作的教师相比，开展户外绿色教育的教师表现出更高的感知情感质量和恢复能力。通过 SEM 分析测试的模型显示，学校的积极情感品质与较高的恢复性相关联，而这又与对学校社会关系的更积极感知相关联，从而提高了生活满意度。总之，这些结果支持了之前的研究，证明了自然体验对心理的有益影响，在学校环境中也是如此。

Per- and polyfluoroalkyl substances (PFASs) have been detected in the influent, effluent, and sludge/biosolids of wastewater treatment plants (WWTPs) globally. Due to their potential to bioaccumulate in humans, wildlife, and the environment over time owing to their seriously persistent nature and/or strong C-F bonds, PFASs can cause public health concerns. Conventional processes in full-scale WWTPs are usually inefficient in PFASs removal from wastewater and sludge, and advanced treatment technologies are needed for PFASs removal. This study intends to briefly (i) summarize the technologies for PFASs remediation in wastewater and sludge; (ii) review PFASs removal in full-scale WWTPs; (iii) discuss some possible theoretical configurations for the wastewater processing train of modern WWTPs for PFASs remediation; and finally (iv) provide future directions. Further research regarding the techno-economic assessment and optimization of treatment technologies in removing PFASs (especially short-chain PFASs) from real wastewater as well as the performance of full-scale WWTPs consisting of advanced innovative efficient treatment technologies for PFASs removal and associated costs (i.e., construction, operation, maintenance, chemical, energy, and amortization) is still required.

Mobility, a vital part of daily life, significantly impacts human well-being. Understanding this relationship is crucial for shaping the future trajectory of mobility, a connection often overlooked in previous research. This study explores the complex relationship between mobility and well-being and proposes a holistic framework for mobility’s future, prioritizing individual and societal well-being. The motivation for this research stems from the growing need to balance technological advancements in transportation with the well-being of diverse populations, especially as the mobility landscape evolves with innovations like autonomous vehicles and intelligent mobility solutions. We employ bibliometric methods, analyzing 53,588 academic articles to identify key themes and research trends related to mobility and well-being. This study categorizes these articles into thematic clusters using the Louvain modularity maximization algorithm, which facilitates the formation of cohesive groups based on citation patterns. Our findings underline the significant impact of mobility on physical, mental, psychological, financial, and social well-being. The proposed framework features four pillars: vehicle, infrastructure and environment, mobility stakeholders, and policy. This framework underscores the importance of collaboration between institutional and individual actions in shaping a future mobility landscape that is technologically advanced, socially responsible, and conducive to an improved quality of life.

In recent decades, the literature on food risk has grown significantly. Consumers are increasingly interested in being informed about the relationship between the food they purchase, their health, and current sustainability goals. In this study, university students’ opinions on food quality attributes were collected through a survey in search of emerging common traits and taking into account the students’ socio-demographic characteristics. The sample for the analysis consists of 5133 students enrolled at the University of Turin (Italy), whose perceptions of food risk are analyzed using hierarchical cluster analysis and principal component analysis. The results reveal the existence of four clusters within the surveyed student population: “Detached”, “Warranty-oriented”, “Inattentive”, and “Made in Italy-oriented”. In particular, the analysis shows a significant influence of age, education level, income, and employment on students’ preferences concerning the purchasing process and food safety. The results also provide some suggestions to stakeholders, underlying the necessity to strengthen the knowledge of the origin of food products and the awareness of the challenges of the global–local food system.

To enhance pomegranate production on marginal gravelly lands, standardized planting techniques were evaluated in an 8-year-old orchard. Trenching, wider pit excavation, pit digging, and auger digs with dimensions of 1 and 2 m were employed. Utilizing native soil from barren land, with or without spent wash, and mixing it with black soil up to 1 m deep, growth parameters, leaf nutrients, fruit production, and fruit quality were assessed. The trench and wider pit methods outperformed others, yielding greater above-ground biomass (>70.3 kg tree−1), root biomass (>24.5 kg, tree−1), and cross-sectional area (>3.30 m2 tree−1). These methods also produced longer roots (>4.0 m tree−1) and higher leaf phosphorus (>0.28%) and potassium (>1.81%) levels, fruit juice content (>48.50%), and total soluble solids (>16.05°) compared to other planting methods. This resulted in higher and more sustainable fruit yield production under the trench and wider pit planting methods (>7.21 t ha−1). Similarly, the native and black soil mixture produced healthy fruit trees, improved fruit quality, and sustainably higher fruit yield over the native soil alone. In summary, the trench and wider pit methods (2–3 m3), combined with a soil mixture, are recommended for sustainable, high-quality fruit production in shallow gravelly terrains, thereby improving food security and the livelihoods of farmers in arid regions.

In summary, the trench and wider pit methods (2–3 m3), combined with a soil mixture, are recommended for sustainable, high-quality fruit production in shallow gravelly terrains, thereby improving food security and the livelihoods of farmers in arid regions.","PeriodicalId":22183,"journal":{"name":"Sustainability","volume":"1 1","pages":""},"PeriodicalIF":3.9,"publicationDate":"2024-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142265254","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
Net Primary Productivity (NPP) is a crucial indicator of ecological environment quality. To better understand the carbon absorption and carbon cycling capabilities of Henan Province, this study investigates the trends and driving factors of NPP across different climatic zones and land use types. The Theil–Sen Median trend analysis method and the Mann–Kendall trend test are employed to monitor NPP changes from 2001 to 2020. The average annual NPP in Henan Province during this period was 414.61 gC·m−2·year−1, showing a significant increasing trend with a growth rate of 3.73 gC·m−2·year−1. Spatially, both the annual average NPP and its increase rate were higher in the western part of Henan compared to the eastern part, and NPP variability was more stable in the southern region than in the northern region. By classifying climatic zones and using the Geodetector method to assess NPP sensitivity to natural factors, the results show that climate and vegetation factors jointly influence NPP variations, with annual precipitation being the primary natural factor affecting NPP trends in Henan Province from 2001 to 2020. By analyzing the NPP gain and loss matrix, the impact of land use changes on NPP was evaluated. Forests had the highest average annual NPP at 483.52 gC·m−2·year−1, and the conversion of arable land to urban areas was identified as the primary land change type leading to NPP reductions. In the subtropical zone of Henan, forests, croplands, and grasslands exhibited higher NPP values and increase rates compared to those in the warm belt. This study provides new insights into the spatial variation of NPP caused by changes in climatic zones and land use types.
