Recent observations have established that dwarf galaxies can host black holes of intermediate mass (IMBH, 100Mȯ < MIMBH ≲ 105 Mȯ). With modern numerical models, we can test the growth of IMBHs as well as their evolutionary impact on the host galaxy. Our novel subsolar-mass (0.8 solar mass) resolution simulations of dwarf galaxies (M* = 2 × 107 Mȯ) have a resolved three-phase interstellar medium and account for non-equilibrium heating, cooling, and chemistry processes. The stellar initial mass function is fully sampled between 0.08–150 Mȯ while massive stars can form HII regions and explode as resolved supernovae. The stellar dynamics around the IMBH is integrated accurately with a regularization scheme. We present a viscous accretion disk model for the IMBH with momentum, energy, and mass conserving wind feedback. We demonstrate how the IMBH can grow from accretion of the cold and warm gas phase and how the presence of the IMBH and its feedback impacts the gas phase structure.

This article aims to reopen discussion of the Renaissance ars historica, a genre that has garnered little attention in modern scholarship. It does so by using a set of computational tools to measure the quantitative occurrence of terms related to artistry and cognition in Johann Wolff's collection of historical-method texts entitled “Artis Historicae Penus” (1579). Like the period's historical writing, which amalgamated aesthetics and historiography, the Renaissance artes historicae belonged to a historiographical paradigm in which the skillful construction of discourse went hand in hand with the search for historical truth. The title of Wolff's anthology accordingly draws an overt connection between the concepts of “ars” and “historia,” yet what did sixteenth-century theorists mean by “art”?

This article explores strategies that allow electronic music performers to engage their audiences and environments in live acts of co-creation. We outline our existing musical practice relying on site-specific sampling and digital mobile technologies that have been tested across a range of participatory music performances. Salient challenges within this performance context are identified and several tools and techniques are proposed as solutions. We then consider how setting-based and sample-based participatory performances can be expanded through gamification strategies. After exploring how notions of playful experience can offer new insights into the nature of audience engagement, we propose several approaches for introducing gamified elements into performative music practices that can expand the scope of audience participation while preserving key aspects of using concert location recordings and musical improvisation. We conclude by discussing the implications of these approaches for the performer–audience relationship and the prospect of musical engagement with the environment before suggesting directions for future research.

Jihadist groups have found a ‘safe haven’ in northern Mali. They have managed this by operating strategically to establish themselves and to develop relationships with local communities, but characteristics of the environment have also facilitated their development and survival. In northern Mali, the political landscape is fragmented, and replete with competition between the central authority and various groups of local elites, who are themselves divided. I conceptualise this fluid environment as a context that incentivises ‘political nomadism’. Using the Tuareg communities as an entry point, I explore the complex dynamics between local and national political actors and jihadist groups in northern Mali. I argue that the jihadist ‘safe haven’ in northern Mali is highly relational and has been facilitated by the form of political nomadism practiced in the region since the 1990s. The article is based on eight months of fieldwork conducted between 2016 and 2017 in Mali and Niger.

This article offers a structural analysis of Cicero's Orator, sections 140–8. Situating Cicero's defence of a form of educational activity in relation to his earlier denials that he is teaching anything, the article proposes an explanation for Cicero's apparent reversal of position rooted in status theory, the conceptual framework developed by Greek and Roman rhetorical theorists for schematizing the points at issue in a case and the corresponding lines of approach that a defender should take. Understanding the status-inspired organization of Cicero's self-defence affords readers smoother passage through a text that is often difficult and obscure. Furthermore, this analysis shows how Cicero deploys rhetorical techniques in defence of his educational endeavours both to support his claim to continued relevance and to exemplify the versatility of the ideal orator whom he portrays in the Orator.

Computability theoretic aspects of Polish metric spaces are studied by adapting notions and methods of computable structure theory. In this dissertation, we mainly investigate index sets and classification problems for computably presentable Polish metric spaces. We find the complexity of a number of index sets, isomorphism problems, and embedding problems for computably presentable metric spaces. We also provide several computable structure theory results related to some classical Polish metric spaces such as the Urysohn space $\mathbb {U}$, the Cantor space $2^{\mathbb {N}}$, the Baire space $\mathbb {N}^{\mathbb {N}}$, and spaces of continuous functions.

This article argues that an intentional acrostic spanning the first five lines of Propertius’ elegy for Cynthia's birthday (3.10), MANE[T], contributes significantly to the poignancy and purpose of the poem. MANE can be read as māne, ‘in the morning’, or manē, ‘stay!’, both of which emphasize the fleeting nature of dawn—and of Cynthia's youthful beauty. MANET can suggest both ‘[art] remains’ and ‘[death] awaits’. All four of these meanings work together to capture the tension between human transience and artistic immortality. The theme is further enhanced by a balancing reverse telestich at the poem's end, ROSA RVES (‘[a] rose, you will fall to ruin’).

House size provides a comparative measure of household wealth that enables archaeologists to track global trends in inequality across a range of sedentary societies. Such approaches hold particular promise for Maya archaeology given its long history of settlement pattern research and recent applications of LiDAR to map large areas surrounding ancient Maya cities. Estimating dwelling size, however, is not a trivial exercise. This article addresses potential confounds associated with geometric-based estimates (volume and area) and compares traditional house size-based measures of wealth with other estimates of house size and quality of life indicators. Settlement pattern data from the Upper Usumacinta Confluence Zone, recently collected by the Proyecto Arqueológico Altar de Sacrificios, combined with previously published excavation data provide a robust dataset to evaluate alternative measures of wealth beyond house size.

The state has long relied on ordinary civilians to do surveillance work, but recent advances in networked technologies are expanding mechanisms for surveillance and social control. In this article, we analyze the phenomenon in which private individuals conduct surveillance on behalf of the state, often using private sector technologies to do so. We develop the concept of surveillance deputies to describe when ordinary people, rather than state actors, use their labor and economic resources to engage in such activity. Although surveillance deputies themselves are not new, their participation in everyday surveillance deputy work has rapidly increased under unique economic and technological conditions of our digital age. Drawing upon contemporary empirical examples, we hypothesize four conditions that contribute to surveillance deputization and strengthen its effects: (1) when interests between the state and civilians converge; (2) when law institutionalizes surveillance deputization or fails to clarify its boundaries; (3) when technological offerings expand personal surveillance capabilities; and (4) when unequal groups use surveillance to gain power or leverage resistance. In developing these hypotheses, we bridge research in law and society, sociology, surveillance studies, and science and technology studies and suggest avenues for future empirical investigation.

Medical-Legal Partnerships (MLPs) have been widely acclaimed for promoting health equity and achieving meaningful outcomes. Yet, little to no research has analyzed if this critical work has been done with communities — through meaningful engagement and building power — or if it has been done for communities without their involvement.

Solar-type stars, including the Sun, have magnetic fields that extend from their interiors to the surface and beyond, influencing both the stellar activity and interplanetary medium. Magnetic activity phenomena, such as coronal mass ejections (CMEs), significantly impacts space weather. These CMEs, composed of plasma clouds with magnetic fields ejected from the stellar corona, pose a potential threat to planets by affecting their magnetosphere and atmosphere. Despite advancements in detecting stellar CMEs, detection remains limited. We focus on understanding CME propagation by analyzing key parameters like position, velocities, and the configuration of stellar magnetic fields. Using spot transit mapping, we reconstruct magnetograms for Kepler-63 and Kepler-411, employing the ForeCAT model to simulate CME trajectories from these stars. Results indicate that CME deflections generally decrease with radial velocity and increase with ejection latitude. Additionally, stars with stronger magnetic fields, such as Kepler-63, tend to cause more significant CME deflections.
