For both Hegel and Badiou, love is one vehicle through which the transition from substance to subject concretely occurs, despite their respective conceptions of this transition differing drastically. Although (amicably) critical of Hegel’s Logic, Badiou—the first systematic continental philosopher since Hegel—never expressly reproaches Hegel’s conception of love, as outlined in both the Logic and the Realphilosophie lectures, but it is not Hegelian love which Badiou champions. His possible criticisms of Hegelian love can only be discerned through his explicit critiques of the Logic, in which he faults Hegel’s denial of absolute difference. Given that Badiouian love is conceived precisely as the subjective experience of absolute difference, his critique of Hegel must play a more significant role in his conceptual rehabilitation of love than is immediately evident. This paper teases out Badiou’s critique of Hegel and examines what it illuminates regarding his conception of love, as well as Hegel’s. I conclude that Badiou’s conception highlights an aspect of Hegelian love which Hegel himself does not sufficiently emphasize, but it remains too one-sided on its own and thus forces one to continue to decide in favour of Hegel.

A clay from Weslatiya that is widely used in Tunisian ceramic production has abundant reserves but generates significant waste, posing environmental concerns if not handled appropriately. This study explores the valorization of this local clay by incorporating ceramic waste (chamotte) and quartz sand to produce eco-friendly materials, in line with sustainability and circular economy principles. X-ray diffraction and scanning electron microscopy analyses reveal that incorporating chamotte at levels exceeding 15% by weight improves the material’s properties. The Young’s modulus of the composite increases to 80 GPa, more than 2.5 times that of the basic clay. Chamotte can replace up to 30% of quartz sand without significantly affecting densification or porosity while preserving structural integrity. This approach offers flexibility in terms of material composition, enhancing performance and promoting sustainability by reusing waste materials for high-performance ceramics in industrial applications.

Recognizing the distributed nature of agency in human–AI interactions, this article proposes a framework for examining the power dynamics that undergird the use of generative AI (GenAI) for language learning. Drawing on Darvin and Norton’s model of investment, it adopts a critical sociomaterial lens to cast a light on the entanglement of bodies, objects and discourse in these interactions, while highlighting how issues of positioning, access to resources, and ideological reproduction emerge from this perspective. Human agency both interacts with and is constrained or amplified by the functionalities of GenAI. To invest in agentive GenAI practices that enable meaningful learning and the achievement of their own intentions, learners must not only recognize the power of GenAI to steer interactions and promote specific ways of thinking, but also resist fully delegating the production of meaning and texts to technology. Cultivating critical digital literacies that recognize how power operates in human-AI interactions is integral to fostering reflexive, inclusive and equitable language learning and teaching in the age of GenAI.

During the first half of the nineteenth century, Mid-Atlantic States expanded guardianship to include habitual drunkards. Legislators in Pennsylvania, New York, and New Jersey empowered courts to put habitual drunkards under guardianship, a legal status that stripped them of their rights to own property, enter into contracts, make wills, and, in some states, even vote. Amid the dramatic nineteenth-century expansion of male suffrage, the habitual drunkard signified a masculine failure of self-government that disqualified propertied men from the privileges of full citizenship. The struggle to define habitual drunkenness, detect the habitual drunkard, and put him under guardianship transformed the courtroom into an arena for contesting the thresholds of compulsion, policing respectable manhood, and drawing the borders of full citizenship in the nineteenth-century United States.

Bentonite is mined globally for use in commercial and industrial applications. In these applications, smectite content and composition are the paramount factors of the bentonite material and control its properties. As bentonite composition and properties can vary significantly over a large mining district or within a single mine, quality control is required including: mineral composition, especially smectite content; cation exchange capacity (CEC); exchangeable cation composition; and smectite crystallochemical features. Differences in bentonite composition locally or over a spatial area stem from the different geological settings present throughout bentonitization. The study aims were to: (1) determine the layer charge (LC) variation of dioctahedral smectite over the Bavarian mining district and within individual mines in the area; and (2) assess the error in smectite content calculations based on CEC data resulting from the actual range of experimentally determined LC values. This information has been missing in the scientific literature, as previous LC methods were laborious or subject to assumptions, making a comprehensive study over a large spatial area impractical. This study employed the use of the recently developed efficient and precise spectroscopic ‘O-D method’, which enabled the LC measurement of 40 samples from eight mines in the Bavarian bentonite mining district, covering an area of 250 km2, within the North Alpine Foreland Basin. Results showed LC values calibrated against the alkylammonium method (LC (AAM)) generally ranged between 0.29 and 0.30 eq per formula unit (FU), with only 10% of samples showing LC values >0.31 eq/FU. This narrow LC range has positive implications for the accuracy of determining smectite content calculated from CEC data, during routine quality control of Bavarian and other bentonites. The average error of the CEC-based smectite contents resulting from LC variations was, on average, ±3 wt.%.

This longitudinal survey examined the effect of the National Healthcare Safety Network’s (NHSN) recently updated Clostridioides difficile test method definition on reporting of hospital-onset C. difficile. Among six hospitals with ≥ 5 years of data available, the updated NHSN definition was associated with improved concordance between predicted versus reported cases.

We apply a synthesis review to revisit the concept, measurement, and operationalisation of social inclusion and exclusion in the context of comparative social policy, integrating the vast literature on the concepts, with the aim of elucidating a clearer understanding of the concepts for use by scholars and policymakers around the planet. In turn, we outline the conceptual development of the concepts, how they have been operationalised through social policy, and how they have been measured at the national and individual levels. Through our review, we identify limitations in extant conceptualisation and measurement approaches and suggest directions for refining conceptual and measurement frameworks to enhance their utility in social inclusion policy, emphasising the concepts’ multidimensional, multilevel, dynamic, and relational essence and highlighting their connection to related concepts such as social capital, social integration, and social citizenship.

We give a notion of boundary pair $(\mathcal{B}_-,\mathcal{B}_+)$ for measured groupoids which generalizes the one introduced by Bader and Furman [BF14] for locally compact groups. In the case of a semidirect groupoid $\mathcal{G}=\Gamma \ltimes X$ obtained by a probability measure preserving action $\Gamma \curvearrowright X$ of a locally compact group, we show that a boundary pair is exactly $(B_- \times X, B_+ \times X)$, where $(B_-,B_+)$ is a boundary pair for $\Gamma$. For any measured groupoid $(\mathcal{G},\nu )$, we prove that the Poisson boundaries associated to the Markov operators generated by a probability measure equivalent to $\nu$ provide other examples of our definition. Following Bader and Furman [BF], we define algebraic representability for an ergodic groupoid $(\mathcal{G},\nu )$. In this way, given any measurable representation $\rho \,:\,\mathcal{G} \rightarrow H$ into the $\kappa$-points of an algebraic $\kappa$-group $\mathbf{H}$, we obtain $\rho$-equivariant maps $\mathcal{B}_\pm \rightarrow H/L_\pm$, where $L_\pm =\mathbf{L}_\pm (\kappa )$ for some $\kappa$-subgroups $\mathbf{L}_\pm \lt \mathbf{H}$. In the particular case when $\kappa =\mathbb{R}$ and $\rho$ is Zariski dense, we show that $L_\pm$ must be minimal parabolic subgroups.

Neurodegenerative diseases (NDDs) are a group of complex disorders marked by pathophysiological mechanisms involving protein aggregation, mitochondrial dysfunction, oxidative stress and neuroinflammation. Irrespective of extensive research advances, NDDs have become a serious global concern and persist as a major therapeutic challenge. In recent years, microRNAs (miRNAs), a class of small non-coding RNAs, have established a pivotal role in combating NDDs. The altered expression of miRNAs is reported to be associated with the progression of various NDDs. This review aims to discuss miRNA biogenesis; dysregulation in NDDs, specifically Alzheimer’s disease, Parkinson’s disease (PD) and amyotrophic lateral sclerosis; their potential as biomarkers; and promising therapeutic targets. Additionally, there are various emerging technologies discussed that are advanced approaches to enhance miRNA-based diagnostics and therapeutics.
