This article examines how disabled people become part of public transport infrastructure through embodied and interactional practices. Drawing on ethnographic fieldwork and video analysis of journeys in Santiago de Chile, it explores how disabled users co-produce the system’s functioning—anchoring themselves in carriages, navigating ticketing processes, or coordinating alighting from buses. Challenging dominant framings of accessibility as material provision or personal independence, the article emphasizes the relational and distributed nature of disability and mobility. It draws on critical infrastructure studies, disability studies, and ethnomethodology to conceptualize public transport as a “coming-together” of bodies and materialities. Rather than merely revealing breakdowns or failure, the analysis foregrounds the everyday labor of care, coordination, and adjustment through which infrastructure is sustained. Disabled people’s embodied practices are shown to be infrastructural in themselves—constitutive of what allows the system to function. This perspective calls for a shift in how urban mobility is conceptualized and designed: not as a neutral system serving passive users but as an interdependent accomplishment involving human bodies, materials, and social relations. The article argues for recognition of this labor, and for planning approaches that value, rather than seek to eliminate, embodied interdependence as part of more just, inclusive urban transport.

本文探讨了残疾人如何通过具体和互动的实践成为公共交通基础设施的一部分。通过对智利圣地亚哥旅行的人种学田野调查和视频分析，它探讨了残疾用户如何共同产生系统的功能——将自己固定在车厢里，导航票务过程，或协调从公共汽车上下来。这篇文章挑战了无障碍作为物质供应或个人独立的主流框架，强调了残疾和流动性的关系和分布性质。它借鉴了关键的基础设施研究、残疾研究和民族方法学，将公共交通概念化为身体和物质的“结合”。该分析不仅揭示了故障或故障，还强调了基础设施赖以维持的日常护理、协调和调整工作。残疾人的具体实践本身是基础设施，是系统运行的组成部分。这一观点要求转变城市交通的概念化和设计方式：不是作为一个服务于被动用户的中立系统，而是作为一种涉及人体、材料和社会关系的相互依存的成就。本文主张承认这种劳动，并主张规划方法重视而不是试图消除体现的相互依存，将其作为更公正、更具包容性的城市交通的一部分。

This paper presents a new mixed-integer linear programming model for managing the size and composition of a workforce that provides home healthcare services. Decisions center around hiring, training, and downgrading in the face of high resignation rates and a fluctuating imbalance between supply and demand. Novel features of the model include a workforce that is characterized by hierarchical skills and various levels of experience, both affecting individual productivity and operational costs. The optimization problem is to determine a weekly hiring, training, and downgrading plan over the long-term to minimize the weighted sum of costs. Constraints include meeting demand, assuring that patients can be assigned the most appropriate caregivers, and maintaining a target level of skills and experience among the staff. Complications concern an annual turnover rate that exceeds 60% as well as uncertain demand. To validate the model, extensive tests were conducted using data provided by a U.S. home health agency. The results show that optimal solutions can be obtained in a few minutes or less for most instances, depending on the number of patients and caregivers. A major insight gained from the study is that it is possible to derive hiring rules that are simple to implement and closely match optimal plans.

Copper is essential for modern economies including: energy systems, data centers, defense applications, space cooling and heating, heavy industry, smart agriculture, transportation, and consumer goods. The presumption persists that the copper needed for all these purposes will be readily available. However, we show that copper is unlikely to be mined fast enough to meet all these needs in the short to medium term. Despite the recent and rapid copper price rise, we suggest that it will have to continue to rise significantly and provide robust price signals for a significant number of known copper deposits to be developed into mines. This price signal will need to be associated with permitting reforms to be successful in several cases. The widening gap should be a matter of political prioritization both in the USA and globally.

铜对现代经济至关重要，包括：能源系统、数据中心、国防应用、空间制冷和供暖、重工业、智能农业、交通运输和消费品。这种假设坚持认为，所有这些用途所需的铜都很容易获得。然而，我们表明，铜的开采速度不太可能快到足以在中短期内满足所有这些需求。尽管最近铜价快速上涨，但我们认为，铜价必须继续大幅上涨，并为大量已知铜矿开发成矿山提供强有力的价格信号。在一些情况下，这种价格信号需要与允许改革取得成功联系起来。不断扩大的差距应该成为美国和全球政治优先考虑的问题。

Background: Cardiometabolic risk factors and conditions are the leading contributors to morbidity and mortality, yet quantifying their causal effects on socioeconomic outcomes using observational data is challenging due to endogeneity. Using genetic variants as instrumental variables, Mendelian randomization (MR) offers a unique approach to strengthen causal inference in this context and has also gained popularity in health economic literature.

Aims: This study aimed to: i) map the current landscape of MR studies evaluating the impact of cardiometabolic exposures on healthcare and socioeconomic outcomes; ii) describe how core MR assumptions were tested and reported; iii) summarize how additional assumptions underlying causal interpretation were discussed.

Methods: We searched MEDLINE and EMBASE for studies applying MR to examine the impact of cardiometabolic risk factors or conditions (e.g., obesity, blood pressure, cholesterol, coronary artery disease, type 2 diabetes) on socioeconomic and healthcare outcomes (e.g., education, income, occupational status, social deprivation, healthcare use and costs, health-related quality of life). Study characteristics, MR design choices, and reporting of assumption testing and causal interpretation were extracted and narratively summarized.

Results: Sixteen studies were included, covering 79 exposure-outcome pairs. Most studies examined the effects of body mass index on employment or healthcare costs. Only one study assessed home ownership, social income transfers, resource utilization, and quality-adjusted life years as outcomes, respectively. Effects of childhood cardiometabolic exposures were rarely examined beyond educational outcomes. UK Biobank was the predominant data source. None of the core MR assumptions were mentioned across all studies. While weak instrument bias was frequently tested, less than 40% of studies assessed associations between instruments and observable confounders as falsification tests. Only few studies discussed monotonicity or homogeneity assumptions.

Conclusions: Although MR is a promising identification strategy for assessing causal effects of cardiometabolic risk on healthcare and socioeconomic outcomes, reporting practices for assumption testing and causal interpretation vary widely. This review highlights opportunities to strengthen transparency and coherence in future MR applications. With increasing data availability and clearer methodological guidance, MR could complement conventional observational approaches in supporting policy decisions.

背景：心脏代谢危险因素和条件是导致发病率和死亡率的主要因素，但由于内生性，使用观察数据量化其对社会经济结果的因果影响具有挑战性。使用遗传变异作为工具变量，孟德尔随机化（MR）提供了一种独特的方法来加强在这种情况下的因果推理，并且在卫生经济学文献中也得到了普及。目的：本研究旨在：i)绘制评估心脏代谢暴露对医疗保健和社会经济结果影响的MR研究的现状；ii)描述如何检验和报告核心MR假设；Iii)总结如何讨论因果解释背后的附加假设。方法：我们在MEDLINE和EMBASE中检索了应用磁共振检查心脏代谢危险因素或状况（如肥胖、血压、胆固醇、冠状动脉疾病、2型糖尿病）对社会经济和医疗保健结果（如教育、收入、职业地位、社会剥夺、医疗保健使用和成本、与健康相关的生活质量）影响的研究。提取研究特征、MR设计选择、假设检验和因果解释的报告并进行叙述性总结。结果：纳入16项研究，涵盖79对暴露-结果对。大多数研究都考察了身体质量指数对就业或医疗成本的影响。只有一项研究分别评估了房屋所有权、社会收入转移、资源利用和质量调整寿命年。儿童时期心脏代谢暴露的影响除了教育结果之外很少被检查。UK Biobank是主要的数据来源。所有研究都没有提到核心MR假设。虽然经常测试弱工具偏差，但不到40%的研究评估了工具和可观察混杂因素之间的关联作为证伪检验。只有少数研究讨论了单调性或同质性假设。结论：尽管MR是评估心脏代谢风险对医疗保健和社会经济结果的因果影响的一种很有前景的识别策略，但假设检验和因果解释的报告实践差异很大。本综述强调了在未来核磁共振应用中加强透明度和一致性的机会。随着数据可用性的增加和方法指导的明确，MR可以在支持政策决定方面补充传统的观察方法。

In Finland, where only few major river systems run free without hydropower production or other artificial constructions, the demand for river restoration efforts is increasing. In a choice experiment for river restoration measures using a latent class model, we identified five distinct preference classes. Classes ranged from cost-conscious supporters of nationwide restoration to respondents favoring measures regardless of costs, as well as those emphasizing new trout and salmon waters or preferring the status quo. The main differences across classes concerned sensitivity to costs, the relative importance of restoring free-flowing river sections versus creating new fish waters, and whether restoration should be geographically restricted. To gain insight into the underlying values and attitudes guiding respondents' choices, we employed constructs of cognitive hierarchy model. Our analysis revealed that individuals favoring new restoration measures without concern for costs exhibited the strongest values and attitudes associated with environmental protection. Conversely, the class preferring the status quo displayed the weakest values and attitudes related to environmental protection. We provide insights into respondents who do not respond to the cost attribute as expected and for whom it is not meaningful to calculate willingness-to-pay estimates.

在芬兰，没有水力发电或其他人工建设，只有少数几条主要河流系统是自由运行的，因此对河流修复工作的需求正在增加。在使用潜在类别模型的河流恢复措施选择实验中，我们确定了五个不同的偏好类别。从支持在全国范围内恢复的注重成本的支持者到支持不计成本采取措施的受访者，以及那些强调新的鳟鱼和鲑鱼水域或更喜欢现状的受访者。各阶层之间的主要差异在于对成本的敏感性，恢复自由流动的河段与创造新的鱼类水域的相对重要性，以及恢复是否应该受到地理限制。为了深入了解指导被调查者选择的潜在价值观和态度，我们采用了认知层次模型的结构。我们的分析显示，支持不考虑成本的新恢复措施的个体表现出最强的与环境保护相关的价值观和态度。相反，偏好现状的班级在环境保护方面表现出最弱的价值观和态度。我们提供了对那些没有像预期的那样对成本属性做出反应的受访者的见解，对他们来说，计算支付意愿估计是没有意义的。
