Language mindsets—traditionally conceptualized as a binary framework centered on learners’ beliefs about the malleability of language abilities—play a critical role in shaping learning behaviors. Considerable research has investigated the relationship between growth and fixed language mindsets and student engagement. However, these studies have largely focused on the separate effects of two mindsets with linear methods, overlooking the complex interplay of language mindsets and their potential nonlinear effects on student engagement. This study employed polynomial regression with response surface analysis, a novel method in educational psychology research, to examine how the congruence and incongruence of the two language mindsets jointly influence student engagement among 505 college EFL learners. The results demonstrated that 1) growth and fixed language mindsets interact with each other, showing a complex nonlinear relationship with student engagement; 2) under congruent conditions of mindsets, the engagement was greater when both growth and fixed mindsets were extremely high; 3) under incongruent conditions, student engagement was more pronounced when growth mindset was higher than fixed mindset. These findings challenge the binary view of mindsets in pedagogy and suggest tailored interventions should account for the dynamic interplay of growth and fixed mindset beliefs.

语言思维——传统上被认为是一个二元框架，以学习者对语言能力可塑性的信念为中心——在塑造学习行为中起着至关重要的作用。相当多的研究调查了成长与固定语言心态和学生参与度之间的关系。然而，这些研究主要集中在线性方法的两种思维模式的单独影响上，忽视了语言思维模式的复杂相互作用及其对学生参与度的潜在非线性影响。本研究采用教育心理学研究中的一种新方法——多项式回归与反应面分析，对505名大学英语学习者的两种语言心态的一致性和不一致性如何共同影响学生的学习投入进行了研究。结果表明：1)成长性思维和固定语言思维相互作用，与学生投入表现出复杂的非线性关系；2)在心态一致的条件下，成长心态和固定心态都非常高时，敬业度更大；3)在不一致条件下，成长心态高于固定心态时，学生的敬业度更显著。这些发现挑战了教学法中心态的二元观点，并建议量身定制的干预措施应考虑到成长和固定心态信念的动态相互作用。

The understanding of Leibniz’s conception(s) of the mathematical infinite has significantly improved in the last thirty years and Eberhard Knobloch’s work, as an editor and as a commentator, has played a crucial role in this evolution. My aim in this note is to assess how these studies have modified and improved our understanding of Leibniz’s views on infinity. I also indicate some avenues it opened for exploration and which are now the object of ongoing researches.

在过去的三十年里，人们对莱布尼茨的数学无限概念的理解有了显著的提高，而埃伯哈德·诺布洛赫作为编辑和评论员的工作，在这一演变中发挥了至关重要的作用。我在这篇文章中的目的是评估这些研究是如何修改和提高我们对莱布尼茨关于无限的观点的理解的。我还指出了它开辟的一些探索途径，这些途径现在是正在进行研究的对象。

Between the years 2022 and 2024 Eberhard Knobloch and Karin Reich prepared and published the critical edition of the letter from Leibniz to James Bruce from November 21, 1712 and Leibniz’s accompanying „Instruction“. In this instruction Leibniz described a globe with declination lines, which was missing. In the beginning it was not known, whether the magnetical globe mentioned in these documents still existed. Detailed researches in Hannover and St. Petersburg until then had not been successful. On October 28, 2022 the globe Nr. 7, located in Göttingen was interpreted as the globe which Leibniz had described. This interpretation is due to Albert Krayer, who knew about the globe since 1986, but he did not know the text from Leibniz.

The mathematician Daniel Augusto da Silva is distinguished for his pioneering contributions to the scientific study of Portuguese pension funds providing survivors’ pensions in the third quarter of the 19th century. The provision of this social protection in Portugal has been documented since the late 18th century, in montepios de sobrevivência. However, it was not until the 20th century that the foundations of such pension funds were based on the principles of actuarial science. This paper provides an analysis of da Silva’s texts on actuarial calculus, placing them in the broader context of the development of this field in Portugal.

数学家丹尼尔·奥古斯托·达席尔瓦（Daniel Augusto da Silva）因其在19世纪第三季度葡萄牙养老基金提供幸存者养老金的科学研究方面的开创性贡献而闻名。自18世纪末以来，葡萄牙在montepios de sobrevivência提供了这种社会保护的记录。然而，直到20世纪，这种养老基金的基础才建立在精算学原理的基础上。本文提供了对达席尔瓦精算文本的分析，将它们置于葡萄牙这一领域发展的更广泛背景下。

It remains controversial whether the human sciences can quantify the phenomena they study. The feasibility of quantification is usually assessed by identifying similarities and differences to quantitative measurement in physics. We argue that the case studies used to exemplify physical measurement are not sufficiently representative to underwrite such assessments. We substantiate this thesis by reconstructing how seismologists quantified “earthquake size.” Seismology demonstrates that quantification can succeed under conditions that, on the one hand, differ from canonical case studies and, on the other, resemble those of the human sciences in relevant respects—seismologists study phenomena that are not amenable to significant experimental control and that cannot be isolated from complex background conditions. This allows us to refute an influential argument for the impossibility of human science quantification, which turns on the claim that experimental control is a necessary condition for quantification (Trendler, 2009). Finally, we draw constructive lessons for the human sciences from the method that seismologists Charles Richter and Beno Gutenberg used to quantify earthquake size. That method starts by introducing (approximate and circumscribed) “placeholder” scales, which can then be extended and revised to account for inevitable disturbing factors in the measurement process. We use this method to identify promising developments but also continued shortcomings in a noteworthy effort at quantification: the Lexile measure of reading comprehension.

人文科学能否量化他们所研究的现象仍然存在争议。量化的可行性通常是通过识别物理定量测量的异同来评估的。我们认为，用于举例说明物理测量的案例研究不足以代表这样的评估。我们通过重建地震学家如何量化“地震大小”来证实这一论点。地震学表明，量化可以在这样的条件下取得成功，一方面，不同于典型的案例研究，另一方面，在相关方面类似于人文科学的研究——地震学家研究的现象不适合重要的实验控制，也不能从复杂的背景条件中分离出来。这使我们能够反驳一个关于人类科学量化不可能的有影响力的论点，该论点转向了实验控制是量化的必要条件的主张（Trendler, 2009）。最后，我们从地震学家Charles Richter和Beno Gutenberg用来量化地震大小的方法中得出了人类科学的建设性经验。该方法首先引入（近似的和限定的）“占位符”量表，然后可以扩展和修改，以解释测量过程中不可避免的干扰因素。我们使用这种方法来确定有希望的发展，但也继续在量化值得注意的努力的缺点：阅读理解的Lexile测量。

This study investigates how TikTok Refugees, users displaced by the TikTok ban, construct and perform their identities in their first posts on Xiaohongshu, a major Chinese social media platform. Drawing on Goffman’s dramaturgical theory and grounded textual analysis of 207 first posts, the study proposes a performative translation model of cross-cultural self-presentation. Five recurring identity roles (Refugee, Witness, Connector, Mediator, and Collaborator) and five performative strategies (Translation, Emotion, Comparison, Ritual, and Authenticity) were identified, showing how digital migrants convert the uncertainty of exile into visible acts of belonging. Findings reveal that the first post functions as a ritualized entry performance oriented simultaneously toward human viewers and algorithmic systems. These performances are the outcome of backstage textual rehearsal, cultural translation, and calibration to platform visibility norms. Identity thus emerges as a dynamic, iterative process of performative translation, where linguistic, affective, and technical elements converge to sustain cross-cultural participation. This study extends Goffman’s dramaturgy into algorithmically mediated and transnational settings by reconceptualizing the digital stage as a mediated environment shaped by visibility logics and affective infrastructures. The concept of performative translation provides a new lens for understanding digital literacy and intercultural competence under platform geopolitics, demonstrating that in global digital ecologies, belonging is performed, ratified, and algorithmically circulated.

这项研究调查了TikTok难民，即因TikTok禁令而流离失所的用户，如何在中国主要社交媒体平台小红书上的第一个帖子中构建和执行他们的身份。本文以戈夫曼的戏剧理论为基础，通过对207篇文章的文本分析，提出了一种跨文化自我呈现的表演翻译模式。五个反复出现的身份角色（难民、证人、连接者、调解者和合作者）和五种表现策略（翻译、情感、比较、仪式和真实性）被确定，展示了数字移民如何将流亡的不确定性转化为可见的归属行为。研究结果表明，第一个帖子的功能是仪式化的入口表演，同时面向人类观众和算法系统。这些表演是后台文本排练、文化翻译和平台可见性规范校准的结果。因此，身份是一个动态的、反复的过程，在这个过程中，语言、情感和技术因素汇聚在一起，以维持跨文化的参与。本研究通过将数字舞台重新定义为由可见逻辑和情感基础设施形成的中介环境，将戈夫曼的戏剧扩展到算法中介和跨国环境中。表演性翻译的概念为理解平台地缘政治下的数字素养和跨文化能力提供了一个新的视角，表明在全球数字生态中，归属是被执行、批准和算法循环的。

This article is devoted to the first general printed catalogue of the École des Ponts et Chaussées (EPC) library, which was published in 1872 and whose production spanned several decades. The article opens with a historical account of the EPC library, and proceeds to examine the principal episodes that shaped the conception, maturation, and implementation of the 1872 catalogue, while its last part is concerned with the place of mathematical sciences—rational and applied mechanics included—within that document. Finally, the article’s conclusion offers some general reflections on the process of designing and crafting library catalogues for engineering schools dedicated to the production of State engineers in 19th century France, while a special attention is given to the “patrimonialization” work carried out by those involved in the devising of the 1872 catalogue.

Psychological well-being (PWB) is crucial for academic success and mental health among foreign language learners. While teacher enthusiasm is known to enhance PWB, its underlying mechanisms are unclear. Integrating emotional contagion theory and self-determination theory (SDT), this study examined how teacher enthusiasm, basic psychological needs (BPNs), and self-determined motivation (i.e., autonomous and controlled motivation) predict PWB in Chinese EFL learners. Data from 3612 university students revealed that teacher enthusiasm, BPNs, autonomous motivation, and controlled motivation each exerted significant positive effects on PWB. Mediation analyses identified BPNs and autonomous motivation as mediators between teacher enthusiasm and PWB, through two pathways: the mediation via BPNs alone, and the chain mediation through BPNs and autonomous motivation. These findings elucidate the psychological need and motivational mechanisms linking teacher enthusiasm to PWB, validating emotional contagion theory and SDT within Chinese EFL context. Theoretical and practical implications for language education and research are discussed.

心理健康对外语学习者的学业成功和心理健康至关重要。虽然教师的热情可以提高PWB，但其潜在机制尚不清楚。本研究结合情绪传染理论和自我决定理论，探讨了教师热情、基本心理需求和自我决定动机（即自主动机和控制动机）对中国英语学习者学习动机的预测作用。来自3612名大学生的数据显示，教师热情、自我动机、自主动机和控制性动机对自我学习行为均有显著的正向影响。中介分析发现，在教师积极性与工作动机之间，工作动机和自主动机通过两种途径起中介作用：一种是单独通过工作动机进行中介作用，另一种是通过工作动机和自主动机进行连锁中介作用。这些研究结果阐明了教师热情与学生自我学习之间的心理需求和动机机制，验证了中国英语语境下的情绪感染理论和教师自我学习。讨论了对语言教育和研究的理论和实践意义。

Background: Innovative research in emerging fields may give rise to future ethical issues. Yet at developmental stages it cannot be reliably known what those issues are. This presents a problem, because it is necessary to anticipate and control for future issues at an early stage. To address this problem, early implementation of ethics tracks in such research makes for an underexplored methodology. The study conducted in this paper aims to contribute to this development by asking what methodologically sound ethical forecasting amounts to and how to best incorporate this. We describe the setup, execution and outcome of an Ethical Foresight Analysis (EFA) conducted with the DarChemDN research program, a multi-study collaboration into the creation of synthetic life from inorganic self-replicating molecules.

Methods: We performed an Ethical Foresight Analysis covering all 10 biochemical studies of DarChemDN. The Delphi methodology was used for extraction and aggregation of expert knowledge.

Results: The study resulted in 12 identified and assessed ethical issues related to DarChemDN's synthetic life research.

Discussion: This paper discusses these outcomes and provides a critical assessment of how this EFA fits into an ethics track using Floridi and Strait's (2021) comprehensive evaluation of EFA's in general and the Delphi methodology in particular.

Background: Nutrition research funded by commercial entities may be subject to bias. To date, no study has examined the prevalence of commercial funding in clinical trials of dietary supplements for weight loss.

Objective: To estimate the prevalence of commercial funding of randomized controlled trials (RCTs) of dietary supplement interventions for weight loss.

Methods: We conducted a rapid review of English-language RCTs published between 1 January 2023, testing dietary supplements for weight loss. Funding sources were extracted from full texts and categorized as industry, nonprofit, trade association, academic, government, or other. Commercial funders, trade associations, and nonprofits were further reviewed for ties to supplement sales.

Results: Of 74 articles reviewed, 59% (n = 44) reported commercial funding, involving 64 unique funders and 118 instances of commercial involvement. More than half of funders sold dietary supplements or had affiliated companies that did, though some affiliations could not be verified due to limited transparency. No nonprofit funders had ties to supplement sales.

Conclusions: The majority of RCTs evaluating dietary supplements for weight loss reported commercial funding. Further research is needed to assess whether such funding influences study findings.

背景：商业机构资助的营养学研究可能存在偏倚。到目前为止，还没有研究调查商业资助减肥膳食补充剂临床试验的普遍程度。目的：评估膳食补充剂干预减肥的随机对照试验（rct）的商业资助情况。方法：我们对2023年1月1日之间发表的英语随机对照试验进行了快速回顾，测试了膳食补充剂的减肥效果。资金来源从全文中提取，分类为行业、非营利组织、行业协会、学术机构、政府或其他。对商业资助者、行业协会和非营利组织进行了进一步审查，以确定是否有关系来补充销售。结果：在74篇综述文章中，59% （n = 44）报道了商业资助，涉及64个独立资助者和118个商业参与案例。超过一半的资助者出售膳食补充剂，或者有关联公司出售膳食补充剂，但由于透明度有限，一些关联公司无法得到核实。没有非营利机构的资助者与补充销售有联系。结论：大多数评估膳食补充剂减肥效果的随机对照试验报告了商业资助。需要进一步的研究来评估这种资助是否会影响研究结果。
