In 2017, archaeologists at Pompeii discovered by far the longest tomb inscription ever found at the city on a monumental tomb. This elogium provided insight into many aspects of the city's social, economic, and political world. One clause attests to the distribution of baked bread in the city. This note argues that the passage provides new evidence from Pompeii that answers two longstanding questions. The first is that of the subject of an often-reproduced Pompeian fresco. The identity of the main figure in the painting is debated: either a baker or a politician. The second is the status, political rank, and network of the owner of the property on which the fresco was discovered. Supported by the evidence of an electoral programma, the painting and inscription illuminate the mechanics of beneficence at Pompeii and serve to identify the residence of someone who operated in the political networks of the 1st-c. CE city at a sub-elite level.

We generalize bounds of Liu–Wan–Xiao for slopes in eigencurves for definite unitary groups of rank $2$ to slopes in eigenvarieties for definite unitary groups of any rank. We show that for a definite unitary group of rank $n$, the Newton polygon of the characteristic power series of the $U_p$ Hecke operator has exact growth rate $x^{1+2/{n(n-1)}}$, times a constant proportional to the distance of the weight from the boundary of weight space. The proof goes through the classification of forms associated to principal series representations. We also give a consequence for the geometry of these eigenvarieties over the boundary of weight space.

In a recent paper, motivated by the study of central extensions of associative algebras, George Janelidze introduces the notion of weakly action representable category. In this paper, we show that the category of Leibniz algebras is weakly action representable and we characterize the class of acting morphisms. Moreover, we study the representability of actions of the category of Poisson algebras and we prove that the subvariety of commutative Poisson algebras is not weakly action representable.

One of the major pillars of the African Union is the integration of peoples and the ability for them to move freely from one member country to another, with the right to reside and practise their trade or profession. This aspect of integration found full expression in the Protocol to the Treaty Establishing the African Economic Community Relating to the Free Movement of Persons, Right of Residence and Right of Establishment, adopted in 2018. Upon operationalization, it will remove obstacles to the movement of people, capital and resources in the region and give expression to aspiration 2 of the African Union Agenda 2063. However, significant challenges lie on the path of its implementation. This article doctrinally reviews the protocol, looking at its prospects for promoting African integration and development, and anticipates some of the problems that the protocol will face. It concludes with recommendations for achieving its lofty but desirable ends.

Sensory differences and anxiety disorders are highly prevalent in autistic individuals with and without ADHD. Studies have shown that sensory differences and anxiety are associated and that intolerance of uncertainty (IU) plays an important role in this relationship. However, it is unclear as to how different levels of the sensory processing pathway (i.e., perceptual, affective, or behavioral) contribute. Here, we used psychophysics to assess how alterations in tactile perception contribute to questionnaire measures of sensory reactivity, IU, and anxiety. Thirty-eight autistic children (aged 8-12 years; 27 with co-occurring ADHD) were included. Consistent with previous findings, mediation analyses showed that child-reported IU fully mediated an association between parent-reported sensory reactivity and parent-reported anxiety and that anxiety partially mediated an association between sensory reactivity and IU. Of the vibrotactile thresholds, only simultaneous frequency discrimination (SFD) thresholds correlated with sensory reactivity. Interestingly, we found that sensory reactivity fully mediated an association between SFD threshold and anxiety, and between SFD threshold and IU. Taken together, those findings suggest a mechanistic pathway whereby tactile perceptual alterations contribute to sensory reactivity at the affective level, leading in turn to increased IU and anxiety. This stepwise association can inform potential interventions for IU and anxiety in autism.

Tippins et al. (2023) challenge I-O psychologists to more actively – in Miller’s oft-quoted APA presidential address – “give psychology away.” Their article provides stirring examples of the impact several of our colleagues have made in giving psychology away. In thinking about how to encourage and facilitate more of us to volunteer, we’d like to share several thoughts on our roles as I-Os, both as individuals and as a community. In particular, we propose that volunteerism is an expression of our calling as I-Os; suggest five roles we can play as individuals; discuss three roles for the community at-large; and conclude with a call to action.

Danon disease is a rare X-linked disorder caused by deficiency of the lysosome-associated membrane protein-2. We report a case of hypertrophic obstructive cardiomyopathy secondary to a novel mutation in the lysosome-associated membrane protein-2 gene in a 10-year-old male adolescent. We performed a modified extended Morrow procedure to minimise the risk of death and improve the patient’s quality of life. The patient did not have exertional dyspnoea, and auscultation did not reveal a cardiac murmur at 1-year follow-up.
