In this paper I offer a defence of absence causation in response to a central challenge: the problem of profligacy. Focussing on two related cases of absence causation, holes and surface absences, the account of absence causation offered for these cases has the following attractions: it captures the central features of many of our common-sense judgments about absence causation in these cases; it doesn’t appeal to norms; and is grounded in salient features of the metaphysics of the cases. As such, there’s a metaphysically respectable, principled criterion for absence causation that solves the problem of profligacy for these cases.

The analysis of the radiocarbon age of dissolved organic carbon (DOC) is fundamental for understanding the aquatic component of the global carbon cycle, yet the technique is not routinely available at radiocarbon laboratories. This study presents validation experiments for an improved wet oxidation method for 14C-DOC analysis in a freshwater matrix. Emphasis in design protocol for the method was placed on the quantitative removal of inorganic carbon, and a background level consistent with modern accelerator mass spectrometry (AMS) radiocarbon measurements. The method utilizes a pre-oxidized potassium persulfate oxidant in crimp-sealed vials with rigorous multi-stage helium purging to achieve and maintain a sample without atmosphere carbon dioxide and the contamination of modern 14C (14C-free). Method validation of 14C-free samples are demonstrated with procedural blanks, phthalic anhydride (PhA), and an International Atomic Energy Agency Oxalic Acid standard (IAEA-C8).

Design Neurocognition, a field bridging Design Research and Cognitive Neuroscience, offers new insights into the cognitive processes underlying creative ideation. This study adopts a micro-perspective on design ideation by examining convergent and divergent thinking as its core components. Using 32-channel EEG recordings, it investigates how educational background (Industrial Design Engineering vs. Engineering Design) influences designers’neural activity (alpha, beta, and gamma frequency bands), behavioral responses, and perceived stress during ideation tasks. Data from forty participants reveal a consistent and meaningful interaction between brain activity, behavior, and self-reported stress, highlighting that educational background significantly modulates cognitive and neural patterns during ideation. Importantly, perceived stress shows strong negative correlations with neural power across all frequency bands, suggesting a close alignment between subjective experience and physiological measures. By integrating neural, behavioral, and psychological data, this study advances the understanding of the neurocognitive mechanisms driving design ideation and establishes a methodological foundation for bridging Design and Cognitive Neuroscience. These findings contribute to building a unified evidence base for future human-centred and neuro-informed design research.

Atop El Castillo, the largest pyramid within the Maya site of Chichen Itza, in Mexico’s Yucatan Peninsula, stand two ruined columns that once portrayed the feathered serpent deity K’uk’ulkan. 3D-imaging technologies have identified scattered sculptural fragments belonging to these columns, allowing a digital reconstruction that opens new possibilities for their conservation.

In 1915, a Denver murder case became a national story, not because of the identities of the perpetrator or victim but because of a reluctant trial witness: Judge Ben B. Lindsey. A pioneer of Progressive Era juvenile justice, Lindsey was charged with contempt of court for refusing to disclose the details that a twelve-year-old boy shared with him. His refusal led to a six-year-long battle over ideas of confidence and secrecy between a juvenile court judge and a minor. This article analyzes the murder trial and consequent contempt of court case as reflective of a clash over questions of law, justice, and public interest and highlights the role of ordinary people, including children, in debating these ideas. It argues that, as legal actors engaged in a conflict between legal formalism and socialized law, members of the public debated their own perceptions and vernacular understandings of law, justice, and the role of the juvenile court.

American states continue to experiment with new forms of electoral institutions, including various nonpartisan election systems. One such rule, the “top-two” procedure, allows all voters to choose any candidate in the primary, advancing whichever two candidates obtain the most votes to the general election. These general elections may feature two candidates of the same party. This paper uses data from California, the largest state to adopt this rule, to examine participation and competition in the last five elections before the top-two procedure (2002 to 2010) and the first five after it (2012 to 2020), investigating the potential trade-off between the roll-off and increased competition. We find that while roll-off occurs with copartisan elections, the compensating increases in competition are substantial. Furthermore, with this system, the meaningful competition shifts toward the higher turnout general elections, which calls into question whether there is much of a participatory cost at all. Additionally, we leverage the unusual cases of write-in candidates to illustrate the electoral dynamics of these elections, highlighting the difficulty of implementing accountability with cross-party elections while demonstrating the behavioral potential of copartisan elections.

Military robotic swarming is expected to herald a disruptive change in warfare. This article analyses how both the technoscientific promises and problematizations of robotic swarming in the military relate to transformations in the way wars are cognized and conducted by liberal societies. This analysis will be conducted through the lens of a more-than-human biopolitics. Firstly, the paper traces how a new understanding of life, established by complexity sciences, has enabled entanglements and translations between different forms of life and how these have informed the military imaginaries and design principles of military swarming. Secondly, the problematization of robotic swarms as potentially running out of human control is re-interpreted in terms of this re-conceptualizing and appropriation of a more-than-human life. The central argument here is that a biomimetic robotic swarm not only inherits the desired properties of a natural swarm but also its inherent risks. Thirdly, it is analysed how military approaches to the government of robotic swarms and their dangerousness move to a less centralized and less direct form of Command and Control (C2), aiming to maximize the benefits of swarming while minimizing its risks. The article concludes by discussing how this new C2 paradigm of governing at the ‘edge of chaos’ points us to the need to rethink the legal ordering of swarming.

This article examines the determinants of the profitability of European wine companies using dynamic panel models, analyzing 1,025 firms from 14 countries between 2015 and 2021. Unlike previous research that focused mainly on financial variables, this study incorporates financial, nonfinancial, macroeconomic, and institutional factors to provide a broader understanding of profitability drivers. Given significant differences between the individual categories, separate analyses were conducted for small and medium-sized enterprises (SMEs) and large and very large companies (LVL) companies. The results show that higher debt reduces profitability, while a higher ratio of cash flow to operating revenue and firm growth improves profitability. Investment in fixed assets increases the profitability of SMEs, while net asset turnover positively affects both SMEs and LVL firms. Labor productivity significantly influences profitability when SMEs and LVL firms are analyzed separately. Public and private limited companies are more profitable than partnerships or sole traders. Finally, the rule of law positively affects SME profitability.

South Korea’s enduring obsession with English education has recently taken a new form in chil-se-ko-si, a Korean term referring to competitive English entrance exams for six- and seven-year-olds. This phenomenon reflects a broader shift toward performance-driven, high-stakes instruction in early childhood, shaped by policy gaps, market expansion, and parental anxiety. This article examines how chil-se-ko-si has become a mechanism of social sorting. It further explores whether such trends remain justifiable in an era increasingly mediated by generative AI. Drawing on a critical policy review that integrates media discourse, government data, and a national survey (Shin et al. 2023), the analysis is grounded in critical discourse analysis and Bourdieu’s theory of symbolic capital. Findings show that early English education is less about language acquisition and more about signaling class status, imposing emotional and financial burdens on families while reinforcing social hierarchies. Medical and educational experts express concern about the developmental and psychological costs of such early academic pressure. As AI tools begin to reshape how English is accessed and used, the persistence of chil-se-ko-si raises urgent questions about what it means to prepare children for the future. The article calls for early English education to be reoriented toward developmental appropriateness, equity, and contextual relevance in a rapidly evolving, technology-mediated world.

I propose a novel account of epistemic reputation as the social standing of agents, groups, and institutions based on their epistemic profiles within a community. Using a functionalist approach, I argue that epistemic reputation is pervasive in our societies because it facilitates navigation within social epistemic networks. Consequently, it holds significant importance as second-order evidence in testimonial belief formation. This proposal integrates reputation research, which has traditionally been relegated to the periphery of social epistemology, into the core of epistemology of testimony. As a result, we gain a deeper understanding of the burden and epistemic responsibility associated with epistemic injustice. This approach also promises to illuminate the concept of humility for experts in a new light.

We consider the associated graded $\bigoplus_{k\geq 1} \Gamma_k \mathcal{I} /\Gamma_{k+1} \mathcal{I} $ of the lower central series $\mathcal{I}\,=\,\Gamma_1 \mathcal{I}\supset \Gamma_2 \mathcal{I}\supset \Gamma_3 \mathcal{I} \supset \cdots$ of the Torelli group $\mathcal{I}$ of a compact oriented surface. Its degree-one part is well understood by D. Johnson’s seminal works on the abelianization of the Torelli group. The knowledge of the degree-two part $(\Gamma_2 \mathcal{I} / \Gamma_3 \mathcal{I})\otimes \mathbb{Q}$ with rational coefficients arises from works of S. Morita on the Casson invariant and R. Hain on the Malcev completion of $\mathcal{I}$. Here, we prove that the abelian group $\Gamma_2 \mathcal{I} / \Gamma_3 \mathcal{I}$ is torsion-free, and we describe it as a lattice in a rational vector space. As an application, the group $\mathcal{I}/\Gamma_3 \mathcal{I}$ is computed, and it is shown to embed in the group of homology cylinders modulo the surgery relation of $Y_3$-equivalence.

The article examines ideologies behind linguistic conversion—a widespread transition to Ukrainian from Russian—which intensified in Ukraine after the onset of Russian aggression in 2014, and particularly after the 2022 full-scale invasion. Employing ‘new speakerness’ as a theoretical lens, the study draws on biographical interviews with twenty-one new full-time Ukrainian speakers recruited among participants in informal language-learning initiatives in Ukraine. The primary focus is on the ways in which the new speakers legitimise their ownership of the Ukrainian language: how they imagine their positions in the socially constructed traditional hierarchies of Ukrainian speakers, based on the mastery of the standard language, and what new ideologies arise out of their challenges. The findings reveal that, in most of the cases, traditional hierarchies are deconstructed as new ideologies prioritising fluency and elevating translingual practice emerge in the linguistic safe spaces of grassroots language courses and community clubs.

Given the growing global prevalence and significant impact of depression and anxiety, both in general and within the workplace, understanding the underlying mechanisms contributing to emotional disorders is essential. This study examined whether self-esteem mediates the relationship between experiential avoidance and emotional disorders, focusing on depression and anxiety. We conducted a cross-sectional analysis of 174 outpatients from a community mental health center, who completed self-report measures of experiential avoidance, self-esteem, depression, and anxiety. We used the PROCESS macro for mediation analysis, and the results indicated that self-esteem significantly mediated the relationship between experiential avoidance and both depression and anxiety. We analyzed the mediation model within the framework of self-determination theory, which suggested that interventions aimed at reducing experiential avoidance and enhancing self-esteem could be effective for emotional disorders. In this study, we highlight the importance of addressing both experiential avoidance and self-esteem in the therapeutic context. We also discuss implications for clinical practice and limitations of the current study.

Cladonia norvegica was originally described from Norway based on different morphological and chemical characters distinguishing the species from C. coniocraea. Shortly after its description, material containing red spots on the thallus was reported from different parts of the world, but the taxonomic status of this form remained unclear. In this study, we investigated the morphological, chemical and genetic differences between the spotless form of C. norvegica and the red-spotted material. Phylogenetic analyses of mycobiont DNA (ITS rDNA, mtSSU, EF-1α) revealed that red-spotted specimens form a well-supported monophyletic clade, distinct from the spotless form of C. norvegica. We therefore describe red-spotted material as a new species, C. rubrotincta, with the type from Norway and we genetically and morphologically confirm occurrences from Austria, Czechia, Estonia, Great Britain and western Canada. The identity of the red pigment was confirmed to be a rhodocladonic acid by HPLC and LC-HRMS. Specimens with red spots exhibit consistently smaller and more irregularly shaped podetia. Additionally, our analysis of photobionts indicated that both species share a similar pool of Asterochloris symbionts. This study underscores the importance of integrating molecular, chemical, and morphological data in lichen taxonomy and provides insights into the distribution and ecological preferences of C. rubrotincta and C. norvegica.

What explains the demand and supply of criminal governance? Contrary to traditional explanations of criminal governance as top-down control, this study integrates bottom-up demands for assistance and top-down supply of aid and coercion. We argue that the demand for criminal governance stems from civilians’ drive to satisfy their primary necessities, while security concerns motivate criminals to supply governance to prevent civilian resistance. The theory focuses on three main factors: economic difficulties, articulation/resistance capacity, and government response. The empirical strategy uses multiple list experiments conducted in Mexico, Honduras, Guatemala, and El Salvador. On the demand side, results indicate that economic difficulties and civilian articulation capacity shape the demand for criminal aid. On the supply side, criminals largely neglect people’s economic needs. When criminals help, they do it for cheap and to neutralize potential civilian resistance or to compete against the state. However, when economic conditions worsen, criminals revert to imposing lockdowns.

Decolonization, naturally, assumes the presence of colonization. For most formerly colonized states decolonization has meant: (1) honoring the inherited colonial treaties; and (2) accepting uti possidetis juris. But what does decolonization mean for the Bandung states that were never formally colonized? For these states, colonial treaties are allegedly unequal while uti possidetis is a restriction on acquiring imagined pre-colonial territories. This essay argues that Bandung’s platitudes about Third World unity notwithstanding, states that were never colonized, or non-colonials, had a different and at times tense relation to some of Bandung’s fundamental commitments. The cases of the law of the sea (LOS) negotiations between 1972 and 1982 and China’s claims to the South China Sea show that these tensions are still unresolved.
