The absolute dating of mortar by accelerator mass spectrometry (AMS) has been the subject of renewed interest for several years. International intercomparison campaigns, called MODIS (MOrtar Dating Intercomparison Study), have been carried out. The first MODIS-1 campaign highlighted limitations in mortar dating, due to the similarity between the primary material to be dated (binder) and the contaminant (exogenous CaCO3). Methods have since emerged to overcome this problem and the need for a good preliminary characterization has been proven. The Laboratoire de Mesure du Carbone 14 (LMC14) took part in the second intercomparison campaign, MODIS2, by applying thermal decomposition increments to distinguish the carbonated binder, the organic matter contaminants (late in formation pyrogenic carbonate, LDH) and limestone. The LMC14 results on MODIS2 are quite conclusive on “pure” re-carbonated lime mortar binders containing little contaminant geological limestone but show their weaknesses for mortars heavily contaminated in Dolomites, which are difficult to discern from the binder. Recommendations for users of radiocarbon (14C) dating on mortar-based materials are made in the conclusion.

In an important contribution to scholarship on measuring democratic performance, Little and Meng suggest that bias among expert coders accounts for erosion in ratings of democratic quality and performance observed in recent years. Drawing on 19 waves of survey data on US democracy from academic experts and from the public collected by Bright Line Watch (BLW), this study looks for but does not find manifestations of the type of expert bias that Little and Meng posit. Although we are unable to provide a direct test of Little and Meng’s hypothesis, several analyses provide reassurance that expert samples are an informative source to measure democratic performance. We find that respondents who have participated more frequently in BLW surveys, who have coded for V-Dem, and who are vocal about the state of American democracy on Twitter are no more pessimistic than other participants.

Arsenoústalečite is a new mineral discovered in a sample collected from the abandoned Ústaleč deposit near Horažďovice, SW Bohemia, Czech Republic. It occurs as rare anhedral grains, up to 40 μm in size, in a calcite gangue, associated with stibioústalečite, hakite-(Hg), berzelianite and uraninite. Arsenoústalečite is dark grey, with a metallic lustre. Mohs hardness is ca. 3½–4; calculated density is 5.730 g/cm3. In reflected light, arsenoústalečite is pale grey with a yellowish shade; it is isotropic. Internal reflections were not observed. Reflectance values for the four COM wavelengths in air [R (%) λ (nm)] are: 33.3 (470); 33.1 (546); 33.0 (589); and 32.9 (650). The empirical formula of arsenoústalečite is (Cu5.81Ag0.17)Σ5.98(Cu5.95Fe0.02Zn0.02Hg0.01)Σ6.00(As1.40Sb0.87Te1.73)Σ4.00(Se10.30S2.32)Σ12.61. The ideal formula is Cu12(As2Te2)Se13, which requires (in wt.%) Cu 34.76, As 6.83, Te 11.63, Se 46.78, total 100.00. Arsenoústalečite is cubic, I$\bar{4}$3m, with unit-cell parameters a = 10.6580(19) Å, V = 1210.7(6) Å3 and Z = 2. The strongest reflections of the calculated powder X-ray diffraction pattern [d, Å (I, %) hkl] are: 3.077 (100) 222, 2.848 (10) 321, 1.946 (12) 521, 1.884(52) 440 and 1.608(21) 622. According to the single-crystal X-ray diffraction data (R1 = 0.0285 on the basis of 334 unique reflections with Fo > 4σFo and 24 refined parameters), arsenoústalečite is isotypic with other tetrahedrite-group minerals. The crystal structure of co-existing stibioústalečite, with an empirical formula of (Cu5.69Ag0.07)Σ5.76(Cu5.80Zn0.13Fe0.06Hg0.01)Σ6.00(Sb1.82As0.42Te1.76)Σ4.00(Se9.52S3.10)Σ12.62 and unit-cell parameters a = 10.6975(16) Å, V = 1224.2(5) Å3 and Z = 2, was refined to R1 = 0.0191 on the basis of 267 unique reflections with Fo > 4σFo and 24 refined parameters. Structural relationships and crystal-chemistry of both members of the ústalečite series are discussed. Arsenoústalečite is named after its type locality, the Ústaleč deposit and its chemical composition. The mineral and its name have been approved by the Commission on New Minerals, Nomenclature and Classification of the International Mineralogical Association (IMA2022-116).

Recent scholarship contends that ancient Mediterranean economies grew intensively. An explanation is that Smithian growth was spurred by reductions in transaction costs and increased trade flows. This paper argues that an ancient Greek institution, proxenia, was among the key innovations that allowed such growth in the period 500–0 BCE. Proxenia entailed a Greek city-state declaring a foreigner to be its “public friend,” a status that conferred both duties and privileges. The functions performed by “public friends” could facilitate economic transactions between communities. Accordingly, network and regression analyses establish a strong relationship between proxenia grants and trade intensity.

This article makes the case for applying recent developments in the history of emotions, and in particular the concept of “emotional arena”, to the study of past polar expeditions. It focuses on the first Antarctic expedition of Jean-Baptiste Charcot (1903–1905), showing how, despite a lack of ideal sources, attention to the role of emotions in his expedition, and in the way it was communicated to the public provides a new understanding of the culture of exploration of the time. The article pays particular attention to two groups of emotions: first, those related to fear, an emotion that Charcot initially was reluctant to say that he had experienced (his position changed under the influence of journalists who saw the emotion as an interesting selling point); and second, anger and hate, emotions that were deemed inappropriate and were omitted from hidden in published accounts of the expedition, even though they appear in other sources.

Recent analytic theology has seen a wave of excellent work on the fundamental problem of Christology, the question of how one and the same person can be human full stop and divine full stop. Along the way, new objections have been raised for a venerable family of Christological views, whose distinctive is the employment of qua-devices to dissolve the difficulties stemming from the dual nature doctrine of Chalcedon and its successors. My objective in this article is twofold. First, I propose to lay out a hierarchy of principles that should guide the search for a Christological theory. I then use these principles to illuminate the best qua-theoretic approach to Christology. Finally, I argue that the best qua-theory is at worst on a par with major recent views.

We give a construction of the free dcpo-cone over any dcpo. There are two steps for getting this result. Firstly, we extend the notion of power domain to directed spaces which are equivalent to $T_0$ monotone-determined spaces introduced by Erné, and we construct the probabilistic powerspace of the monotone determined space, which is defined as a free monotone determined cone. Secondly, we take D-completion of the free monotone determined cone over the dcpo with its Scott topology. In addition, we show that generally the valuation power domain of any dcpo is not the free dcpo-cone.

A game that characterizes equivalence of structures with respect to all first-order sentences containing a given number of quantifiers was introduced by Immerman in 1981. We define three other games and prove that they are all equivalent to the Immerman game, and hence also give a characterization for the number of quantifiers needed for separating structures. In the Immerman game, Duplicator has a canonical optimal strategy, and hence Duplicator can be completely removed from the game by replacing her moves with default moves given by this optimal strategy. On the other hand, in the last two of our games there is no such optimal strategy for Duplicator. Thus, the Immerman game can be regarded as a one-player game, but two of our games are genuine two-player games.

Can and should judges refer to the natural law? I address these questions from the point of view of James Wilson, paying specific attention to a question the scholarship does not address: Why does Wilson believe judges can (and must), in certain instances, refer to natural law? I develop a new taxonomy of Wilson's conception of judgment that answers this question. Wilson's definition of judgment as including the moral sense and reason, and his division of reasoning into demonstrative, moral, and legal reasoning, indicate why he countenances judicial recourse to natural law in certain cases yet remains committed to popular sovereignty and judicial restraint. Wilson describes “judgments of nature” as intuitive judgments based on self-evident truths and articulates how judges might be called upon to make certain judgments based on a manifest repugnancy to the natural law. His judicial decisions confirm this commitment to natural law and judicial restraint.

In this paper, we expand on existing studies of Canadian Inuit art in the international arena by examining ways in which this new art served domestic purposes, focusing primarily on the 1950s and 1960s. The Canadian government developed and promoted Inuit art as part of its project to transform Inuit from semi-independent hunters into modern Canadian citizens. In this effort, Canada took up and assimilated Inuit art as a genuine Canadian cultural product, presenting it as diplomatic gifts and for other forms of international cultural diplomacy. Previous studies of Canadian Inuit art from that era have noted the ways that the promotion of Canadian Inuit art supported the young nation’s claims to a deep history, while simultaneously marking the country’s distinction from both the United States and the United Kingdom. In the context of the Cold War, the promotion of Canadian Inuit art also asserted Canada as an Arctic power. Labelled as “primitive modernist” fine art, Inuit sculpture and prints provided a stark contrast to the contemporaneous socialist realist art of the Soviet Union and its allies. We argue that the success of the Inuit art program sustained a belief among government officials that their programme to remake Inuit lives and livelihoods would succeed. Inuit art likely deflected attention from the many things that were going wrong with that northern modernisation project.

Throughout the history of television, American audiences have participated in a tradition of programs that follow a consistent structure: Amateur musicians and entertainers are offered an opportunity to display their talent on stage, competing for audience votes to win first prize and a chance at stardom. This article contributes to a growing literature on the significance of televised talent shows, demonstrating how their remarkable longevity and representational power stems from their configuration as a “format,” the set of guidelines that structure and constrain the content of each broadcast—an aesthetic process grounded in exclusion. Through their formatting, I argue, these programs reify the notion of “talent” at the heart of talent shows, transforming a multidimensional and context-contingent assemblage of musical abilities into a seemingly stable object able to be recognized, rated, and ranked. Musical auditions offer a microcosm of formatting's role as a means of training audiences’ attention. They normalize the practice of eliminating whatever (or whomever) is deemed unworthy—on these programs and in the wider world. Through analyzing examples from Ted Mack and the Original Amateur Hour (1948), The Gong Show (1978), and The Voice (2017), the article demonstrates how beneath the widely discussed content of contestant demographics, judge commentary, or audience voting results, the talent show format serves to obscure the contradictions upon which meritocracy's cruel optimism rests.

We provide explicit bounds for the Riemann zeta-function on the line $\mathrm {Re}\,{s}=1$, assuming that the Riemann hypothesis holds up to height T. In particular, we improve some bounds in finite regions for the logarithmic derivative and the reciprocal of the Riemann zeta-function.

Les pays ayant une structure politique fédérale sont souvent confrontés aux revendications de leurs États membres pour obtenir plus d'autonomie politique. Pour répondre à ces revendications, les théoriciens du fédéralisme multinational ont proposé de reconnaître un droit à l'autodétermination interne qu'ils ont pris soin d'encadrer de diverses manières. Bien qu'intéressante, cette proposition pourrait toutefois s'avérer insuffisante pour répondre aux inégalités entre les peuples au sein d'une même fédération. C'est la thèse que nous défendrons dans le présent article. Nous montrerons que le concept d'autodétermination interne défendu par Kymlicka reste indéterminé et ouvre la porte à des interprétations plus exigeantes.

This article explores the responses of the South African competition authorities to the impact of the COVID-19 pandemic on the socio-economic rights of consumers in relation to the price gouging of essential and medical supplies. After discussing the constitutional and legislative context of socio-economic rights and excessive pricing, it examines the first case in which the competition authorities were called upon to decide on the excessive pricing of medical supplies during COVID-19. The article finds that, while the competition authorities were swift to interpret the Competition Act widely and act against suppliers charging excessive prices, there remains a gap in South Africa's legislative framework as there is no specific legislation regulating price gouging during states of pandemic or disaster. The article identifies the need for legislative development and concludes by offering recommendations for addressing future incidents of price gouging.

Goodman defends that most maligned aspect of the rhetorical tradition: eloquence. Surely, one would think that eloquence, by its very nature, speaks for itself and quite effectively so, with all the pleasing and persuasive effects of a grand style. Perhaps popular audiences are easily carried along by decorous speech, but Goodman addresses his defense to theorists of politics who tend to greet obvious rhetorical flourish with a deep suspicion of manipulation and deception, or at least of frivolity. On this view, the best thing that can be said about eloquence in its classical form is that it poses no serious threat since the modern advent of mass society and large-scale democracy marks its demise. Goodman forces readers to reconsider the story of the rhetorical tradition's elitist, manipulative, and obsolete character through an engaging, nuanced, and unexpected retelling of Ciceronean eloquence as a tradition that spans the ancient and modern world, one that survives and responds to the challenges of democratic judgment in large polities. Goodman's compelling and insightful book poses an important challenge to theorists of democracy, both contemporary and historical, to take eloquence seriously as an invitation to democratic judgment.
