Another funerary portrait from Cyrenaica in the British Museum

A peculiar and very distinct group of portraits have in recent years aroused the interest of an increasing number of students of Roman art. These are the Cyrenaican funerary portraits, some 117 of which were studied and published for the first time as a separate series by E. Rosenbaum in 1960. Several of these portraits have found their way into European collections of ancient sculpture in these last two centuries. One is presently housed in the Museo Nazionale in Rome, and six are in the possession of the Museum Authorities in Malta.peer-reviewe

Portraits, Power, and Patronage in the Late Roman Republic

Recent work in ancient art history has sought to move beyond formalist interpretations of works of art to a concern to understand ancient images in terms of a broader cultural, political, and historical context. In the study of late Republican portraiture, traditional explanations of the origins of verism in terms of antecedent influences — Hellenistic realism, Egyptian realism, ancestral imagines — have been replaced by a concern to interpret portraits as signs functioning in a determinate historical and political context which serves to explain their particular visual patterning. In this paper I argue that, whilst these new perspectives have considerably enhanced our understanding of the forms and meanings of late Republican portraits, they are still flawed by a failure to establish a clear conception of the social functions of art. I develop an account of portraits which shifts the interpretative emphasis from art as object to art as a medium of socio-cultural action. Such a shift in analytic perspective places art firmly at the centre of our understanding of ancient societies, by snowing that art is not merely a social product or a symbol of power relationships, but also serves to construct relationships of power and solidarity in a way in which other cultural forms cannot, and thereby transforms those relationships with determinate consequence

The finiteness of a group generated by a 2-letter invertible-reversible Mealy automaton is decidable

We prove that a semigroup generated by a reversible two-state Mealy automaton is either finite or free of rank 2. This fact leads to the decidability of finiteness for groups generated by two-state or two-letter invertible-reversible Mealy automata and to the decidability of freeness for semigroups generated by two-state invertible-reversible Mealy automata

Qubit-portraits of qudit states and quantum correlations

The machinery of qubit-portraits of qudit states, recently presented, is consider here in more details in order to characterize the presence of quantum correlations in bipartite qudit states. In the tomographic representation of quantum mechanics, Bell-like inequalities are interpreted as peculiar properties of a family of classical joint probability distributions which describe the quantum state of two qudits. By means of the qubit-portraits machinery a semigroup of stochastic matrices can be associated to a given quantum state. The violation of the CHSH inequalities is discussed in this framework with some examples, we found that quantum correlations in qutrit isotropic states can be detected by the suggested method while it cannot in the case of qutrit Werner states.Comment: 12 pages, 4 figure

Stress Strengthens Memory of First Impressions of Others' Positive Personality Traits

Encounters with strangers bear potential for social conflict and stress, but also allow the formation of alliances. First impressions of other people play a critical role in the formation of alliances, since they provide a learned base to infer the other's future social attitude. Stress can facilitate emotional memories but it is unknown whether stress strengthens our memory for newly acquired impressions of other people's personality traits. To answer this question, we subjected 60 students (37 females, 23 males) to an impression-formation task, viewing portraits together with brief positive vs. negative behavior descriptions, followed by a 3-min cold pressor stress test or a non-stressful control procedure. The next day, novel and old portraits were paired with single trait adjectives, the old portraits with a trait adjective matching the previous day's behavior description. After a filler task, portraits were presented again and subjects were asked to recall the trait adjective. Cued recall was higher for old (previously implied) than the novel portraits' trait adjectives, indicating validity of the applied test procedures. Overall, recall rate of implied trait adjectives did not differ between the stress and the control group. However, while the control group showed a better memory performance for others' implied negative personality traits, the stress group showed enhanced recall for others' implied positive personality traits. This result indicates that post-learning stress affects consolidation of first impressions in a valence-specific manner. We propose that the stress-induced strengthening of memory of others' positive traits forms an important cue for the formation of alliances in stressful conditions
