The present study constitutes a first contribution to the understanding of the French pronoun que dalle (‘nothing’). First, we looked at its syntactic flexibility, its semantic strength in conveying zero quantification, and its pragmatic role in informal language. Then we compared que dalle with its near synonym rien and analysed its development. The results can be summarized as follows. On a descriptive level, we can conclude that, in spite of their different diaphasic distribution, que dalle functions in much the same way as rien, but the former differs from the latter in terms of syntax (subject position, attributive adjective), stylistics and especially pragmatics. On a methodological level, we hypothesized that que dalle originates in the exceptive structure ne…que (‘only’) but the corpus data were insufficient to demonstrate this assumption. On a theoretical level, different processes, i.e. lexicalization and grammaticalization, could be distinguished. We acknowledge that individual quantifiers can be very different in nature and have different diachronic paths: the development of que dalle differs from that of rien in its postverbal use, and it tends toward inherent negativity in fragment answers.
The aim of this article is to show that Hegel’s understanding of ontological dependence can solve what Jonathan Schaffer calls the ‘problem of heterogeneity’. While a solution to this problem is crucial to ensure the plausibility of any monist theory, canonical versions of monism in the history of Western philosophy have struggled to provide such a solution. First, the paper argues that the solutions offered by contemporary monist theorists such as Michael Della Rocca, Terry Horgan, Mathjasz Potrč and Jonathan Schaffer, are also inadequate. While acknowledging the promise of Schaffer’s revision of traditional understandings of ontological dependence, the paper argues that the understanding of dependence as priority, which Schaffer proposes as an alternative, is indeed insufficient to solve the problem of heterogeneity effectively. Secondly, the paper considers Hegel’s relevance to this debate. Offering a monist interpretation of Hegel’s metaphysics, the paper shows that Hegel identified the problem of heterogeneity as a central challenge for his philosophy. Finally, the paper argues that, while building on a criticism of traditional understandings of ontological dependence similar to Schaffer’s, Hegel’s notion of ‘reflection’, or ‘absolute negativity’, provides a better alternative understanding of ontological dependence than Schaffer’s priority, overcoming the shortcomings of traditional understandings of dependence while also not incurring the problems weighing on Schaffer’s notion of priority.
Moral injury is a potentially deleterious mental health outcome that can follow exposure to events that challenge one’s moral code. Theoretical models suggest a multi-faceted self-concept may support adaptation following such events. However, little is known about the relationship between self-concept complexity and outcomes following potentially morally injurious events.
Aims:
This cross-sectional study investigated hypothesized relationships between self-concept complexity and outcomes in adults (n=172) exposed to potentially morally injurious events.
Method:
Participants completed validated measures of event-related distress, traumatic stress, depression and anxiety, and a self-complexity task in which they provided multiple descriptors of their self-concept. Responses were coded for overall diversity, defined as number of categories of self-descriptors, and role diversity, defined as number of social and activity-based roles.
Results:
Multiple regression analyses found greater role diversity independently predicted lower event-related distress, while overall self-diversity and total number of self-descriptors did not.
Conclusion:
Findings indicate diversity in active facets of the self (e.g. relational or activity-based roles) may buffer the effects of a potentially morally injurious event.
Contemporary research on far-right politics has relied predominantly on the use of binaries between the ‘far/extreme/(populist) radical right’ and the so-called ‘mainstream’, and a ‘waves’ metaphor to historicise different eras of the post-World War Two far-right. In this article, we probe these categories and binaries, problematising hegemonic depictions, the consequent assumptions underpinning them, and what this means for resistance to reactionary politics. By reflecting on the current state of the field, summarising dominant approaches and their potential limitations, we arrive at our key contribution: a revised definition of the term ‘far right’ which shifts the focus away from categorisation towards an understanding of far-right politics as a political position. In turn, our approach also presents both a challenge to and evolution of the ‘waves’ metaphor which accounts for processes of mainstreaming and rests on a critical account of the mainstream itself. Our conceptualisation problematises traditional binaries while pointing to a ‘fifth wave’ of far-right politics in which the identities of the mainstream and far right are mutually constitutive. To illustrate our conceptual contribution, we conclude our article with a case study on the interaction between the far right and mainstream in UK politics.
Experiences in Groups is a revolutionary text in the understanding and analysis of group dynamics which remains highly relevant to mental health practice today. This article considers its key themes as well as its development in the context of Wilfred Bion’s work as a doctor and a psychoanalyst.
In this study, we investigate the sedimentation of spheroidal particles in an initially quiescent fluid by means of particle-resolved direct numerical simulations. Settling particles with three different shapes – oblate spheroid, sphere and prolate spheroid – but fixed Galileo number $Ga=80$ and density ratio $\gamma =2$ at volume fraction $\phi =1\%$ are considered. Oblate and prolate particles are found to form column-like clusters as a consequence of the wake-induced hydrodynamic interactions in the suspension. This effect, together with the change of particle orientation, enhances the mean settling velocity of the dispersed phase. In contrast, spherical particles do not exhibit clustering, and settle with hindered velocity in the suspension. Furthermore, we focus on the pseudo-turbulence induced by the settling particles. We report a non-Gaussian distribution of the fluid velocity and a robust $-3$ power law of the energy spectra. By scrutinizing the scale-by-scale budget, we find that the anisotropy of the particle-induced pseudo-turbulence is manifested not only by the uneven allocation of turbulence kinetic energy among the different velocity components, but also by the anisotropic distribution of energy in spectral space. The fluid–particle interactions inject energy into the vertical velocity component, thus sustaining the turbulence, while pressure redistributes the kinetic energy among the different velocity components. The clustering of oblate/prolate particles significantly increases the energy input at large scales, forcing elongated flow structures. Moreover, the redistribution and nonlinear transfer of the energy are also intensified in the presence of particle clustering, which reduces the anisotropy of the particle-induced pseudo-turbulence.
This study employs volume-of-fluid-based computational fluid dynamics modelling to investigate the coupled effects of surface wettability and inflow vapour velocity on R134a ($p/p_{cri}=0.25$) condensation heat transfer in horizontal tubes. The results demonstrate that both the condensation heat transfer coefficient (HTC) and Nusselt number consistently increase with rising vapour velocity, indicating enhanced convective heat transfer at higher flow rates. Within this overall trend, the influence of surface wettability varies significantly across different velocity regimes. At moderate inlet velocities (10 m s−1), surface wettability demonstrates maximum impact, with the HTC enhancement exceeding 19.1% between peak and minimum values, optimising at contact angles of 120$^\circ$–140$^\circ$. As velocity increases to 20 m s−1, while surface wettability effects persist with $\gt$11.7 % enhancement, convective heat transfer becomes increasingly dominant, showing $\gt$38.8 % improvement in the maximum HTC compared with the 10 m s−1 case. At higher velocities (40 m s−1), the influence of surface wettability diminishes substantially, with the HTC variation reducing to $\gt$1.04 %. At extreme velocities (80 m s−1), surface tension effects become negligible compared with vapour shear forces, resulting in minimal (0.53 %) variation across different contact angles. The equivalent Reynolds number peaks at 20 m s−1, indicating optimal conditions for condensate formation and flow characteristics. These findings provide crucial insights for condensation system design, suggesting that while increasing velocity generally enhances heat transfer performance, surface wettability modifications are most effective at moderate velocities, while high-velocity applications should prioritise flow dynamics and system geometry optimisation.
While we now have a relatively good understanding of low-Reynolds-number hydrodynamics, and elegant techniques to dissect it, one cannot truly say the same for yield-stress fluids. For these materials, the nonlinearity associated with the yield stress complicates analysis and prevents the use of many of the techniques used for slow viscous flow. Simultaneously, the presence of a yield stress introduces a range of new features into the problem beyond those of traditional Stokes flow. Accordingly, in this essay, we discuss the impact of a yield stress in the relatively simple setting of two-dimensional, steady, inertialess flow. The main goals are to establish intuition for the dramatically different features that can be introduced to the flow by the yield stress, and to outline the various tools available to the modeller to construct and interpret these flows.
Previous research has characterized those resisting slavery as quite atypical of the enslaved population: most of them being young, male, and engaged in particular occupations. In this article, we study transgressive behavior among an enslaved population quantitatively. We employ a unique census from the Caribbean island of St. Croix in 1846, which allows us to study not only the characteristics of those that transgressed the masters’ order in some way, but also to compare them with those of the entire enslaved population on the island. We find that the individuals in our dataset who transgressed the oppressive institution were, in many respects, quite typical of the entire enslaved population under study. Opposition to the oppressive system could be found among all groups of enslaved persons in the studied society. Nonetheless, we find that specific characteristics, such as marital status and gender, were more likely to be associated with transgression on St. Croix.
This article defines and defends three Rawlsian rationales for a cultural turn in education for democratic citizenship within digitized societies. Due to the importance of political culture for realizing deliberative democracy, it is misguided to hold that a primary or exclusive focus of such education should be on learning how to use digital tools for engaging in politics. Pace this technique- or skills-oriented focus, this article argues that the educational responses to the wide-ranging cultural developments of the digital political public sphere should not be a matter of “training” but of “cultivation.” Accordingly, democratic education for digital citizenship should pay attention to nurturing citizens’ political virtues so that, when they are dealing with fundamental political questions, they are willing to comply with the requirements of public reason and a corresponding duty of civility.
The aim of this work is to prove a new sure upper bound in a setting that can be thought of as a simplified function field analogue. This result is comparable to a recent result of the author concerning an almost sure upper bound of random multiplicative functions. Having a simpler quantity allows us to make the proof more accessible.
Anthropogenic actions are likely to harm dung beetle populations directly through habitat loss and indirectly through the cascading effects of large mammal depletions. Despite the reliance of dung beetles on mammal dung, there are only a handful of studies that have directly assessed the impact of habitat degradation and associated mammalian loss on dung beetle populations in Africa. We evaluated whether patterns in dung beetle species abundance, richness, and body size can be associated with mammalian herbivore abundance and species richness, habitat structure, and the distance between sample sites. Additionally, we ascertained how the presence of elephants (Loxodonta africana) may affect a dung beetle assemblage by determining which species could be used as bioindicators of elephant presence. We found herbivore and overall mammal abundance explained 17% of dung beetle assemblage structure, 2% of dung beetle abundance, 10% of dung beetle species richness and, 15% of the variation in dung beetle body size. Habitat structure explained 27% of dung beetle assemblage structure, 11% of dung beetle abundance, and 14% of the variation in dung beetle body size. Spatial distance between trapping locations explained 13% of the dung beetle assemblage structure, 4% of species richness, 3% of abundance, and but had no effect on dung beetle body size. We also identified four dung beetle species that may be used in future management plans as bioindicators of elephant density Afromontane Forest in East Africa. This information may become especially important for future monitoring as it is predicted that the areas in which elephants occur in Afromontane Forest are set to decline due to deforestation, and the expansion and intensification of agriculture.
The origins of “wolf warrior diplomacy” have been a focus of studies on Chinese diplomacy in the Xi Jinping era. Building on existing research that emphasizes its foreign origins, our study zooms into a micro-level factor: aggressive journalistic questioning. We investigate the linguistic and interactional dynamics between foreign media and the Chinese Ministry of Foreign Affairs (MFA) to assess and highlight its effects on aggressiveness in Chinese diplomatic discourse. Empirically, our analysis is based on a qualitative analysis of 4,556 question–answer dyads taken from MFA press conferences. Overall, our results lend strong support to the causal relevance of this micro-level factor. Aggressive questioning from foreign journalists significantly increases the aggressiveness of the Chinese MFA’s diplomatic rhetoric, although considerable variation exists across issue areas.
Reliable population estimates are one of the most elementary needs for the management of wildlife, particularly for introduced ungulates on oceanic islands. We aimed to produce accurate and precise density estimates of Philippine deer (Rusa marianna) and wild pigs (Sus scrofa) on Guam using motion-triggered cameras combined with distance sampling to estimate densities from observations of unmarked animals while accounting for imperfect detection. We used an automated digital data processing pipeline for species recognition and to estimate the distance to detected species. Our density estimates were slightly lower than published estimates, consistent with management to reduce populations. We estimated the number of camera traps needed to obtain a 0.1 coefficient of variation was substantial, requiring > ten-fold increase in camera traps, while estimates with precision of 0.2 or 0.3 were more achievable, requiring doubling to quadrupling the number of camera traps. We provide best practices for establishing and conducting distance sampling with camera trap surveys for density estimation based on lessons learned during this study. Future studies should consider distance sampling with camera traps to efficiently survey and monitor unmarked animals, particularly medium-sized ungulates, in tropical, oceanic island ecosystems.
