The traditional account of the criminal trial holds that its fundamental purpose is to search for the truth—that is, the truth of whether the accused factually committed the alleged crime. However, purely truth-seeking accounts, as well as more nuanced side-constraint and pluralist accounts, fail to adequately explain the relationship between the epistemic principles and those of political morality shaping the criminal trial. In response, this article proposes that we understand the criminal trial first and foremost in terms of its purpose as a public procedure concerned with the legitimate use of coercive state powers against a particular person. Specifically, the criminal trial is a procedure that calls upon the state to provide a public justification for exercising its criminal law powers to convict and punish the accused. This account preserves the importance of establishing factual guilt because doing so is an essential part of the state’s justificatory burden.
Free and open public debate is a cornerstone of democratic representation, yet many politicians refrain from participating in policy debates. This study examines how political violence contributes to such silencing and whether it disproportionately affects historically marginalized groups. Using a unique Swedish politician survey (five waves, N = 43,000), we analyze whether violence reduces marginalized politicians’ participation in debates and whether it disproportionately silences debates challenging hegemonic male interests. We find that women and immigrant-background politicians are significantly more likely than their counterparts to report withdrawing from public debates because of violence and to avoid a broader range of topics. Women are particularly likely to refrain from debates on gender equality, while immigrant-background politicians are not more likely to avoid immigration debates. These chilling effects suggest that violence can narrow the range of voices present in policy debates, potentially diminishing marginalized groups’ ability to represent constituents and reinforcing hegemonic men’s political dominance.
In a recent article published in this journal, Holman, Merolla, and Zechmeister (2022; 2024) report a decrease in support for U.K. Prime Minister Theresa May following the 2017 Manchester bombing, using data from the British Election Studies. Our analysis, however, reveals that once a linear time trend is considered, the bombing does not significantly affect public reactions. We replicate their study with Gallup World Poll data and likewise find no decline in May’s approval rating. Extending the analysis, we examine major terrorist attacks in African countries led by men and similarly find no rally effect. Together, these results cast doubt on terrorism’s capacity to trigger rally ’round the flag dynamics and challenge claims of a gendered pattern whereby women leaders face unique penalties in crises. We argue that broader comparative evidence is necessary before concluding whether citizens rally around, or retreat from, leaders in the wake of terrorism.
This paper sets out the need for, and potential offered by, introducing social media into teaching global challenges. We argue that teaching on global challenges should involve teaching with, through, and about social media as a place of politics. This paper suggests that using social media in our teaching can help to equip students with critical digital literacies as a set of skills for engaging, understanding, and analysing digital materials. We also argue that digital spaces can offer real potential to open dialogue and thought on global challenges in our classrooms. The article presents reflections from our own classroom experiences to think through how social media offers the potential to re-work hierarchies and unpack knowledges of world politics that are taken for granted. In doing so, we are engaged with wider academic discussions on how digital pedagogies are connected to and can enact critical pedagogies. Finally, the article sets out a research agenda that can take this forward to better understand how students learn through social media and how we can best incorporate this into our teaching as a discipline.
The Ordovician to Silurian diploporite family Gomphocystitidae is here defined by the possession of at least some unilateral spiral ambulacra composed of adambulacral plates each of which bears a single facet for unknown erect feeding structures (probably biserial brachioles). Pyrocystites, which also has unilateral spiral ambulacra, is rejected as a gomphocystitid because it lacks a regular ambulacral structure. Accepted genera are distinguished on oral and ambulacral structure. Fungocystites has at least one bilateral ambulacrum with facets on both sides. All other genera have five unilateral spiral ambulacra. Celticystis has a mouth surrounded by four oral plates; Gomphocystites and Fresticystis have five or more orals forming the mouth frame. In Fungocystites, Celticystis, and Fresticystis, the two posterior orals also contribute to the periproct frame; in Gomphocystites, the two plates between the mouth and anus are arranged one above the other. “Protocrinus” sparsiporus Bather, 1906, from the Ordovician of Myanmar, is assigned to “Gomphocystites?” because it has spiral ambulacra and adambulacral plates identical to other gomphocystitids, but its oral plating is unknown. Gomphocystitids are known from North America, Europe, and Asia.
The functional morphology of unilateral spiral ambulacra is reviewed. It is geometrically impossible to maintain both equal spacing and regular left–right alternation of brachioles in a spiral ambulacrum. Arranging brachioles on the outside of the curve allows more to be developed and orients them with the food groove downstream, the preferred orientation for feeding in living crinoids. Unilateral spiral ambulacra arose due to functional constraints.
To explain why Vladimir Putin launched Russia’s invasion of Ukraine, this article foregrounds a crucial but understudied dimension: national memory. It argues that both discontinuity in national memory and dislocation between national memory and territory threaten states’ ontological security. The Soviet collapse marked a profound break in Russia’s national memory. To restore the ontological security thus shattered, Russia’s ruling elite adopted a narrative of radical continuity of Russian statehood, linking Kievan Rus, the Grand Duchy of Moscow, the Romanov Empire, the Soviet Union, and the Russian Federation into an unbroken thousand-year tradition. Yet by placing its origins in independent Ukraine, this narrative was inherently precarious. While mending the discontinuity in national memory, it produced a dislocation between memory and territory, rendering Russia ontologically vulnerable. By asserting their own claim to Kyiv as the birthplace of Ukrainian nation- and statehood, Ukraine’s ruling elite exposed this dislocation and laid bare both the precarity of the radical continuity narrative and Russia’s resulting ontological vulnerability. The Kremlin’s response was to seek political – and, when that failed, military – control over Ukraine to redress this dislocation and eliminate the sources of ontological vulnerability that flowed from the radical continuity narrative.
Shock–boundary-layer interactions on hypersonic cone-step flows exhibit a range of intrinsic unsteady behaviours, from shear-layer oscillations to large-scale pulsations. This work investigates the unsteadiness in a cone-step geometry at Mach 6 under quiet-flow conditions at different free-stream Reynolds numbers using time-resolved schlieren imaging and spectral proper orthogonal decomposition. Experimental results are compared with high-fidelity axisymmetric and three-dimensional simulations. Results demonstrate regime transition in the parameter space, across the unsteadiness boundary, all the way from shear-layer breakdown to shock system oscillations and ultimately to large-amplitude pulsations. The dominant mode in the experiments and the simulations corresponds to a Strouhal number St$\approx 0.17$ for small oscillations reducing to St$ \approx 0.13$ for large pulsations. A detailed description of the unsteady shock dynamics and an analysis of the nonlinear limit cycle is presented.
This paper examines the simultaneous use of the older handgun and the newer harquebus by Ming Chinese armies before and after the Imjin War (1592–1598), a conflict which saw the Japanese launch a destructive invasion of the Korean peninsula. Although the conflict foregrounded the value of the harquebus in the eyes of many Chinese, its aftermath saw a number of Ming Chinese civil and military officials continuing to affirm the value of the handgun vis-à-vis the harquebus and developing the designs and tactical roles of both types of firearm. Against the backdrop of their discourse on hand-held firearms, I will argue, in this paper, that the Eurocentric focus of modern military scholars has caused them to underestimate the advantages that the older handgun still held over the harquebus in the different Ming Chinese context. In Ming China, the harquebus was valued primarily for its accuracy, which led it to be assigned a different tactical role and undergo a different technological developmental trajectory compared to early modern Europe. Nevertheless, Ming designs tended towards a universal infantry firearm anticipating the solution eventually adopted by early modern European armies: a relatively accurate bayonet-equipped harquebus capable of high rates of fire.
Do men respond to a masculinity threat by adopting more conservative political attitudes? A highly cited 2013 study by Willer et al. – drawing on substantial work in social psychology – argues in the affirmative, reasoning that endorsing conservative views allows men to reaffirm their gender identity. In two experiments with student convenience samples (Ntotal 100–110, Nmen 40–51), the authors find consistent evidence: inducing masculinity threat increases support for war, homophobic attitudes, and endorsement of dominance hierarchies. We conduct a preregistered replication of this foundational study using a nationally representative probability sample (Ntotal 2774, Nmen 2073). Contrary to original findings, we observe no consistent evidence that masculinity threat alters political attitudes. We further do not find support for design differences between the replication and original study driving contrasting findings. Our results call into question the robustness of evidence linking masculinity threat to political attitudes and underscore the importance of re-evaluating widely accepted findings with representative, large samples.
Bed shear stress is a key parameter governing sediment transport and fluxes at the sediment–water interface. In vegetated channels, predicting bed shear stress, especially for rough beds, remains a challenge. This study developed a unified theoretical model for bed shear stress that smoothly spans conditions from bare bed to vegetated bed for both smooth and rough beds. Building on phenomenological turbulence theory, the model relates bed shear stress to the characteristic velocities of the larger energy-containing eddies and the smaller, near-bed eddies, with the new assumption that the bottom boundary layer (BBL) thickness controls the larger, energy-containing eddy length scale. The BBL was defined as the region within which the bed shear stress contributed significantly, compared to vegetation drag, and a force balance predicted that the BBL thickness scales with the ratio of bed shear stress to vegetation drag. In the limit of zero vegetation density, the BBL thickness equals the water depth, and the bed shear stress model reduces to the classical bare bed formulation. With increasing vegetation density (drag), the thickness of the boundary layer decreases, and the bed friction coefficient increases, which is consistent with previous observations. For rough beds, the bed friction coefficient increases with bed roughness, but is not dependent on the mean velocity. In contrast, for smooth beds, the bed friction coefficient decreases with increasing mean velocity. The coupled models for bed shear stress and BBL thickness were compared against 114 physical and numerical experiments from multiple previous studies.
Soil biodiversity is crucial to the maintenance of multiple critical ecosystem functions and services. However, remarkably little is known about the conservation status of most soil-dependent species. To better understand the current situation, we determined the number of soil-dependent species listed in the various categories of the IUCN Red List of Threatened Species. Firstly, a definition of soil-dependent species was developed for IUCN Red List purposes, and this definition facilitated the identification of 8,653 currently listed soil-dependent species. These species included 503 invertebrate and fungal species assessed during the current study; these species were chosen as they were based on priorities for the Red List Strategic Plan, and IUCN Species Survival Commission (SSC) Specialist Group interests. We discuss progress and constraints on the IUCN Red List assessment of soil-dependent species worldwide. Our recommendations for the IUCN SSC to improve the IUCN Red List as a source of information on conservation of soil-dependent species are: (1) scaling up of SSC assessment processes for soil-dependent invertebrates and fungi, including establishment of a Soil Biota Working Group, in line with the IUCN Red List Strategic Plan; (2) building closer connections with other organizations and agencies researching and monitoring soil biodiversity; and (3) broader engagement with and education of governments, landholders and the public as to the fundamental importance of the conservation of global soil biodiversity.
Cambrian tidal flat deposits of the Elk Mound Group at Blackberry Hill, Wisconsin, USA, provide some of the earliest body fossils of euthycarcinoids, phyllocarids, and scyphozoans. Also, some of the earliest evidence of animal activities on land, alongside a diverse ichnofauna, have been observed. Here we expand the ichnotaxonomic diversity of that site, emend the diagnosis of Protichnites, discuss the recent reinterpretation of Protichnites eremita, and establish Seilacherichnus new ichnogenus and Climactichnites blackberriensis new ichnospecies. What may be the first fossil evidence of an animal feeding on a scyphozoan at Blackberry Hill or equivalent Cambrian tidal flats is reported. Ichnotaxa not previously illustrated or described from Blackberry Hill include Siskemia isp., Diplopodichnus isp., Stiallia pilosa, and Cochlichnus? isp. This expansion of the ichnotaxonomic diversity observed in the Blackberry Hill strata further illustrates the early exploitation of tidal flats.
This paper examines the 2016 trial of Ahmad Al Faqi Al Mahdi by the International Criminal Court (ICC) through the lenses of discourse analysis and linguistic anthropology, with a focus on how trial actors navigated legitimacy challenges. Al Mahdi, a member of Ansar Dine, was charged with the war crime of intentionally directing attacks against religious and historic buildings in Timbuktu, which were UNESCO World Heritage sites. This paper argues that the trial actors used a rhetorical “local-to-global parallelism” which sought to consolidate a global range of constituencies and legitimate the ICC’s actions both normatively and sociologically. The local-to-global parallelism served to “talk into existence” a broad-based victimhood, which reinforced the court’s symbolic authority and its claims to jurisdiction. It also relied heavily on intertextual connections between the ICC and UNESCO, thereby legitimating the prosecution of cultural heritage destruction as a grave international crime.
This article is an exploration of leisure practices of military families inside military social institutions such as military summer camps and orduevis (officers’ clubs). Introducing generations of military families to aestheticized forms of seaside leisure as well as bodily forms of self-discipline and militarized forms of sociality, summer camps and orduevis have allowed military families to recognize themselves as a distinct social group and develop classed and racialized sensibilities of cultural difference since the 1950s. Building on ethnographic research among military families, this article examines the role of leisure in the cultivation of the tastes, habits, and sensibilities that define white, modern, secular, and middle-class citizenship for military families.
