We have considered a simple word game called the word-morph. After making our participants play a stipulated number of word-morph games, we have analyzed the experimental data. We have given a detailed analysis of the learning involved in solving this word game. We propose that people are inclined to learn landmarks when they are asked to navigate from a source to a destination. We note that these landmarks are nodes that have high closeness-centrality ranking.

The importance of electrical signalling in bacteria is an emerging paradigm. Bacillus subtilis biofilms exhibit electrical communication that regulates metabolic activity and biofilm growth. Starving cells initiate oscillatory extracellular potassium signals that help even the distribution of nutrients within the biofilm and thus help regulate biofilm development. Quorum sensing also regulates biofilm growth and crucially there is convergence between electrical and quorum sensing signalling axes. This makes B. subtilis an interesting model for cell signalling research. SpoOF is predicted to act (...) as a logic gate for signalling pathway convergence, raising interesting questions about the functional nature of this gate and the relative importance of these disparate signals on biofilm behaviour. How is an oscillating signal integrated with a quorum signal? The model presented offers rich opportunities for future experimental and theoretical modelling research. The importance of direct cell‐to‐cell electrical signalling in prokaryotes, so characteristic of multicellular eukaryotes, is also discussed. (shrink)

Low-wage migrant workers in Singapore are legally entitled to healthcare provided by their employers and supported by private insurance, separate from the national UHC (universal health coverage) system. In practice, they face multiple barriers to access. In this article, we describe this policy-practice gap from the perspective of HealthServe, a non-profit organisation that assists low-wage migrant workers. We outline the healthcare financing system for migrant workers, describe commonly encountered barriers, and comment on their implications for the global UHC movement’s key (...) ethical concepts of fairness, equity, and solidarity.

The "only pretension, of which I am tenacious," wrote Hazlitt, "is that of being a metaphysician"; but his metaphysics, and particularly what this book identifies as his power principle, has until now been neglected. This exciting book studies Hazlitt's development of the power principle as a counter to the pleasure principle of the Utilitarians, and examines the revelation of power in his philosophy of discourse, his account of imaginative structure, his theory of genius, and his moral theory.

Antonio Ruiz is an officer who took part in the Argentine 1976–1983 military rule and disappeared the body of a tortured woman. My aim is to offer an ethnographic account of the embodiment of the knowledge of bodies—the local moral worlds in which the officer Antonio and his wife lived and legitimated state violence by imagining themselves as victims, and Antonio subsequently followed his commander’s order and buried the body of a tortured woman. The armed forces provided soldiers of the (...) armed formal manuals in which political violence was described as an ever-present threat. At home Antonio and his wife exchanged accounts detailing the risk of armed struggle to their fledgling family, with Antonio carrying out commissions of repression as father and husband and not only soldier. The narratives officers constructed and acted upon about themselves as imagined victims linger to this day in contemporary Argentina in the form of the disappeared—the missing thousands who remain unaccounted for, buried in unknown, clandestine graves or drowned alive at sea, with thousands of family members suspended in doubt, unsure where the disappeared might truly be, and whether they live or died.

Linear logic, introduced by Girard, is a refinement of classical logic with a natural, intrinsic accounting of resources. This accounting is made possible by removing the ‘structural’ rules of contraction and weakening, adding a modal operator and adding finer versions of the propositional connectives. Linear logic has fundamental logical interest and applications to computer science, particularly to Petri nets, concurrency, storage allocation, garbage collection and the control structure of logic programs. In addition, there is a direct correspondence between polynomial-time computation (...) and proof normalization in a bounded form of linear logic. In this paper we show that unlike most other propositional logics, full propositional linear logic is undecidable. Further, we prove that without the modal storage operator, which indicates unboundedness of resources, the decision problem becomes PSPACE-complete. We also establish membership in NP for the multiplicative fragment, NP-completeness for the multiplicative fragment extended with unrestricted weakening, and undecidability for fragments of noncommutative propositional linear logic.

An embedding of the implicational propositional intuitionistic logic into the nonmodal fragment of intuitionistic linear logic is given. The embedding preserves cut-free proofs in a proof system that is a variant of IIL. The embedding is efficient and provides an alternative proof of the PSPACE-hardness of IMALL. It exploits several proof-theoretic properties of intuitionistic implication that analyze the use of resources in IIL proofs.

Healthcare facilities in receiving countries regularly encounter guest workers whose need for acute or subacute care triggers the prospect of termination of employment and repatriation. In these scenarios, country‐specific migration and employment policies and norms of medical professionalism and ethics offer some guidance, but also create tensions. It is not clear under what conditions such medical repatriation is ethically permissible.This paper analyses the application of a previously articulated criteria for the ethical medical repatriation of undocumented immigrants, to the situation of (...) documented guest workers, with focus on the context of Singapore. We examine how these standards could be adapted and applied to the provision of care for guest workers, and argue that healthcare institutions and medical professionals have a duty to intervene in employers’ decisions to repatriate guest workers for medico‐economic reasons when repatriation essentially amounts to ‘patient dumping’. Barriers and challenges in implementing the criteria, and their possible solutions will be discussed. (shrink)
