This paper examines how the design and realisation of a concert presentation entitled Drawing Sound in Space led to the concept of digital spatial notation. Seven Australian composers were commissioned to create digital scores for an electroacoustic chamber music ensemble, and scores were shared with the audience. The author argues that contemporary digital notation practices enhance live performances of new music by expanding concepts of the audiovisual to include alternative notational approaches engaging with space, creating a ‘spatial notation’. Further, Drawing Sound in Space aimed to transform musicianship and audience experience by offering a more immersive encounter with music notation as a multimodal, social practice where audience engagement and musical understanding are enhanced. A theoretical framework is provided to facilitate the analysis of each work, where semiotic expansion, temporal engagement, distributed agency and spatial reconfiguration are discussed. Through different approaches to presenting music notation in Drawing Sound in Space, the project sought to provide audiences with a novel concert experience whilst simultaneously challenging composers to design notation intended for audiences as well as performers.

Using calibrated radiocarbon dates, this study investigates climate signals recorded in fluvial sedimentary archives from southern Poland, eastern Netherlands, and eastern Germany. Summed probability density functions (PDFs) were constructed and analyzed in the context of INTIMATE stratigraphy. The results indicate that fluvial sedimentation and erosion processes were closely linked to climate fluctuations, particularly during GS/GI and GI/GS transitions. The analyses indicate multi-scale relationships between regional geomorphological processes and global climate trends during the period from 50 to 15 cal kBP. This study provides a reconstruction of Late Pleistocene fluvial activity and highlights the need for more precise radiocarbon dates to refine correlations between regional and global climate events.

We prove a common refinement of theorems of Bergfalk and of Casarosa and Lambie-Hanson, showing that under certain hypotheses, the higher derived limits of a certain inverse system of abelian groups $\mathbf {A}$ do not vanish. The refined theorem has a number of interesting corollaries, including the nonvanishing of the second derived limit of $\mathbf {A}$ in many of the common models of set theory of the reals and in the Mitchell model. In particular, we disprove a conjecture of Bergfalk, Hrušák, and Lambie-Hanson that higher derived limits of $\mathbf {A}$ vanish in the Miller model.

The topic of this thesis lies in the intersection between proof theory and algebraic logic. The main object of discussion, constructive reasoning, was introduced at the beginning of the twentieth century by Brouwer, who followed Kant’s explanation of human intuition of spacial forms and time points: these are constructed step by step in a finite process by certain rules, mimicking constructions with straightedge and compass and the construction of natural numbers, respectively.

The aim of the present thesis is to show how classical reasoning, which admits some forms of indirect reasoning, can be made more constructive. The central tool that we are using are induction principles, methods that capture infinite collections of objects by considering their process of generation instead of the whole class. We start by studying the interplay between certain structures that satisfy induction and the calculi for some non-classical logics. We then use inductive methods to prove a few conservation theorems, which contribute to answering the question of which parts of classical logic and mathematics can be made constructive.

Capitalism is in trouble, or so we have been told. I argue that Adam Smith has a lot to teach us about the future of capitalism. I first examine recent discussions about the current challenges and criticisms against capitalism such as the productivity slowdown, waning competition, the role of globalization, rising inequality, and climate change. I emphasize that there are some global trends, but there are also important national and regional differences reflecting differences in institutions and policy. Not only natural-scientific technology, but also social-scientific technology—that is, governance, policy, and institutions—matter. Then, I explain what Smith can teach us. First, Adam Smith conceives a truly inclusive capitalism: he takes income distribution into account when he argues for the desirability of economic development. Second, inclusive capitalism requires broad formation and sharing of knowledge among people. Third, the expansion of exchange and trade has beneficial effects, but we should be aware of its distributional consequences. Fourth, institutions matter. Fifth, proper law and institutions—the “system of natural liberty”—are essential to a well-functioning market economy. However, the “system of natural liberty” is not automatically achieved. Policy and institutions are history-dependent; therefore, history matters.

Since 2014, transcatheter paravalvular leak closure with the Occlutech Paravalvular Leak Device has been successfully accomplished in adults with high technical success. We describe the first successful use of the Occlutech Paravalvular Leak Device in the left atrio-ventricular valve in the United States in a 5-year-old child with a history of previously repaired atrio-ventricular septal defect.

The discovery of Middle Bronze Age field systems at Fengate, to the east of Peterborough, Cambridgeshire (Pryor 1980), in the 1970s, was hugely significant for Bronze Age studies in eastern England. Since then, gravel quarry excavations along the western edge of the East Anglian Fens – several of which have become vast, long-running landscape projects – have shaped our understanding of the region’s prehistory. This paper will examine new evidence from the (comparatively) ‘upland’ region of East Anglia, to the south and east of the Fens – primarily through two case study landscapes: South Cambridgeshire (along the Cam Valley) and East Norfolk (the Bure and Yare/Wensum Valleys). Both areas have seen extensive archaeological investigation over the past 15 years and offer new perspectives on the region’s Bronze Age, where land division and settlement context appear different to that of the Fenland and where burial rites display a diversity that has until recently been largely unrecognised. Recent and upcoming publication of these landscapes highlights the need for up-to-date synthesis and review of the region’s Middle Bronze Age evidence, and accordingly, the wider East Anglian context is also briefly considered here, in the hope of providing stimulus for further research and analysis.

Wolff-Parkinson-White syndrome, characterised by accessory pathways, is rarely seen with dextrocardia. We present a case of situs inversus-dextrocardia with Wolff-Parkinson-White syndrome successfully treated via catheter ablation using 3D mapping (EnSite Precision®). Adjustments included reversed electrocardiogram (ECG) electrode placement, EnSite patch positioning, and fluoroscopic views. Coronary sinus access required counterclockwise manoeuvers. Mapping identified a left-sided accessory pathway, necessitating transseptal puncture with mirror-image adjustments. Ablation at the optimal site resulted in success. This case highlights the feasibility of catheter ablation in dextrocardia with tailored procedural modifications.
