The 2021 Integrated Review was informed by two assumptions: that leaving the EU would allow a more agile foreign policy based on ad hoc groups; and global shift in power towards Indo-Pacific meant UK needed to engage with region. Jamie Gaskarth argues missing element this strategy is networked approach. Using insights of network theory social analysis, policymakers should be aiming analyse dyna...

Conducting system operations (such as upgrade, reconfiguration, deployment) for large-scale systems in cloud is error prone and complex. These operations rely heavily on unreliable cloud infrastructure APIs to complete. The inherent uncertainties and inevitable errors cause a long-tail in the completion time distribution of operations. In this paper, we propose mechanisms and deployment archite...

This study investigates the utility of personality traits and secondary goals as predictors of selfpresentation tactics employed by Facebook users. A structural equation model of self-presentation tactics on Facebook was proposed and tested. Although fit of the initial model was good, the final model, eliminating three paths and adding two others, yielded a significantly better fitting model. F...

A cross-cultural study was conducted with managers from the United States and China to investigate differences in influence behavior. Managers rated the effectiveness of different influence tactics for several representative situations. Significant differences were found between American and Chinese managers in a large, multinational company with facilities in both countries. The results were r...

We examine seller tactics in 1177 eBay auctions. The largest volume sellers make rather homogeneous choices; smaller sellers are more heterogeneous. Some tactics, such as starting the auction with a ‘Buy it Now’ offer, appear to increase revenue. Perhaps due to intense competition, however, the overall impact of most tactics appears to be quite small. The main exception is the use of a secret r...

Algorithm synthesis transforms a formal specification into an efficient algorithm to solve a problem. Algorithm synthesis in Specware combines the formal speicifcation of a problem with a highlevel algorithm strategy. To derive an efficient algorithm, a developer must define operators that refine the algorithm by combining the generic operators in the algorithm with the details of the problem s...

We introduce ProverBot9000, a state-of-the-art tool for proof automation and assistance. ProverBot9000 examines partially finished Coq proofs and proposes tactics to make progress on the proof. It generates these tactics using a neural network-based language model of Ltac. ProverBot9000 is trained on human-generated proofs so it suggests tactics that human experts are likely to use in a given p...

We present a comprehensive set of tactics for working with a shallow embedding of a higher-order separation logic for a subset of Java in Coq. The tactics make it possible to reason at a level of abstraction similar to pen-and-paper separation-logic proof outlines. In particular, the tactics allow the user to reason in the embedded logic rather than in the concrete model, where the stacks and h...

This paper discusses the relationship between transformational programming and theorem proving. It illustrates the use of the theorem proving environment as a basis for a program construction tool DEBATE 1 (Deduction Based Transformational Environment) which is under construction in University College Dublin. Using a theorem proving framework directly would require the user to be familiar with ...
