The impetus for this study was a review of the Society for American Archaeology (SAA) 86th Annual Meeting program in 2021. Finding that no single poster or presentation referenced looting or antiquities trafficking despite these issues being ethical considerations that all SAA members are expected to recognize, we sought to investigate whether this was an irregularity – perhaps due to the virtual format of the meeting – or whether it was more common than not. For a broader understanding of if, how, and where these topics are discussed by archaeologists outside of the SAA, we expanded the investigation and studied the archives of 14 other archaeological and anthropological conferences. The results of the study show that despite there being an overall increase in mentioning looting and antiquities trafficking at conferences, it remains a niche and infrequently discussed topic.1

According to relational egalitarianism, justice requires equal relations. In this paper, I ask the question: can equal relations be unjust according to relational egalitarianism? I argue that while on some conceptions of relational egalitarianism, equal relations cannot be unjust, there are conceptions in which equal relations can be unjust. Surprisingly, whether equal relations can be unjust cuts across the distinction between responsibility-sensitive and non-responsibility-sensitive conceptions of relational egalitarianism. I then show what follows if one accepts a conception in which equal relations can be unjust, including why it provides a reason to grant some people less political power than others.

Recently, there has been growing interest in the concept of political anxiety. One important question that remains unanswered is whether political anxiety is just a symptom of general anxiety—that those reporting anxiety tied to politics are the same individuals who would already score highly on measures of general anxiety. Using survey data collected in 2023 (N = 436), we find that measures of political and generalized anxiety do not appear to be tapping into a single underlying construct. In addition, the systematic correlates of these measures identified by previous literature are not equivalent predictors of the different types of anxiety. Politics seems to be a source of apprehensiveness and worry that affects individuals who are not necessarily suffering from general anxiety.

In this paper, we establish the sharp asymptotic decay of positive solutions of the Yamabe type equation $\mathcal {L}_s u=u^{\frac {Q+2s}{Q-2s}}$ in a homogeneous Lie group, where $\mathcal {L}_s$ represents a suitable pseudodifferential operator modelled on a class of nonlocal operators arising in conformal CR geometry.

Multimorbidity, the existence of two or more concurrent chronic conditions in a single individual, represents a major global health challenge. The Nutrition Society’s 2023 Winter Conference at the Royal Society, London focused on the topic of ‘Diet and lifestyle strategies for prevention and management of multimorbidity’, with symposia designed to explore pathways for prevention of multimorbidity across the lifecourse, the role of ageing, the gut-brain-heart connection and lifestyle strategies for prevention and management of multimorbidity. It also considered machine learning and precision nutrition approaches for addressing research challenges in multimorbidity. The opening plenary lecture discussed advancing diet and lifestyle research to address the increasing burden and complexity of multimorbidity. The two-day programme concluded with a plenary which addressed the key dietary risk factors and policies in multimorbidity prevention.

We use potential analysis to study the properties of positive solutions of a discrete Wolff-type equation

$$ \begin{align*} w(i)=W_{\beta,\gamma}(w^q)(i), \quad i \in \mathbb{Z}^n. \end{align*} $$

Here, $n \geq 1$, $\min \{q,\beta \}>0$, $1<\gamma \leq 2$ and $\beta \gamma <n$. Such an equation can be used to study nonlinear problems on graphs appearing in the study of crystal lattices, neural networks and other discrete models. We use the method of regularity lifting to obtain an optimal summability of positive solutions of the equation. From this result, we obtain the decay rate of $w(i)$ when $|i| \to \infty $.

Genetically complete yet authorless artworks seem possible, yet it is hard to understand how they might really be possible. A natural way to try to resolve this puzzle is by constructing an account of artwork completion on the model of accounts of artwork meaning that are compatible with meaningful yet authorless artworks. However, I argue that such an account of artwork completion is implausible. Therefore, I leave the puzzle unresolved.

This paper discusses some of the major ethical issues that arise in connection with the widespread holding of cultural heritage by private collectors. If, as many people believe, and UNESCO has affirmed, cultural heritage is, in some morally significant sense, everyone’s heritage, then the private acquisition of cultural heritage, although widely permitted in law, raises some significant ethical questions. I discuss the nature of the tension between public heritage and private ownership of heritage items and the possibility that more might be done by law to regulate the activities of private collectors before arguing the merits of a shift in the mindset of collectors from thinking of themselves as the unfettered owners of the heritage they acquire towards conceiving themselves primarily as stewards who protect and preserve that heritage on behalf of the wider community. There follows a detailed examination of practical ways in which collectors can discharge their stewardship role to the best effect, emphasizing, in particular, the fresh opportunities for doing so afforded to collectors by the new digital environment.

Despite his influence on those interested by leisure, Marx's own conception of leisure is rarely discussed. Insofar as it is, he is generally either thought to see leisure as free time or as indistinct from necessary labour in communist society. In this article, I suggest that by reading Capital and the Grundrisse through an Aristotelian lens, we can find a third potential conception of leisure in Marx, which shares three features in common with Aristotle's. Leisure is distinct from free time simpliciter, it is a “state-condition” people are in when they perform ends in themselves, and it is constitutive of the final end. I conclude that adopting a conception of leisure grounded in this Marxian conception could have implications for contemporary debates around free time and the value of leisure goods like arts and culture.

Sweden’s adoption of proportional representation (PR) is interesting because it involved static structural and institutional factors, well captured by variance-based left-threat thesis, and four temporal factors—sequencing, timing, historical change, and duration—that historical case studies highlight. We integrate these two sets of factors. We fuse the more static, temporally homogeneous world created by the left-threat thesis, that is well suited to explain cross-sectional variations, with the more dynamic, temporally heterogenous world presumed by the case studies that is attuned to temporal processes. It illustrates how comparative historical analysis (CHA) can translate temporal anomalies into generalizable temporal mechanisms and how nested analysis, together with causal graphs, provide helpful tools for updating theories. We ultimately employ an abductive approach that evaluates evidence not just for its inferential leverage of confirming theories but also for its inductive potential to generate new, more test-worthy hypotheses.

Otoliths are an excellent tool for analysing the pattern of habitat use between adults and juveniles and connectivity between fish populations. Larimus breviceps is a species belonging to the family Sciaenidae, which has an important role in the marine food chain, as it is one of the most abundant and frequent species in the bycatch of coastal shrimp fisheries in Brazil. The present study aimed at comparing the otolith shape of specimens collected in three different Brazilian coastal areas: Sergipe (SE), northeastern region; São Paulo (SP), southeastern region; and Paraná (PR), southern region. In a laboratory, 88 otoliths were extracted, photographed, and the contour was analysed by the wavelet method (32 from SE, 28 from SP, and 28 from PR). The otolith contours varied between sampling sites. Linear discriminant analysis correctly reclassified 60.23% otoliths by the sampled sites, with the best reclassifications occurring in SE (62.5%), followed by PR (60.71%) and SP (57.14%). Multivariate analysis of variance also evidenced significant differences in contours among the sampling sites (F = 2.3; P < 0.005). Thus, two morphotypes of otoliths were found for L. breviceps: one from Sergipe (northeastern Brazil) and the second one from southeastern–southern Brazil, indicating connectivity between the populations off São Paulo and Paraná, to be confirmed by future genetic studies.

The aim of this paper is to determine the asymptotic growth rate of the complexity function of cut-and-project sets in the non-abelian case. In the case of model sets of polytopal type in homogeneous two-step nilpotent Lie groups, we can establish that the complexity function asymptotically behaves like $r^{{\mathrm {homdim}}(G) \dim (H)}$. Further, we generalize the concept of acceptance domains to locally compact second countable groups.
