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.

In this paper I discuss some consequences and manifestations of a mereology of structured wholes in chemistry, with particular reference to the concept of atoms in molecules.

While temporal considerations are of prime importance for chemical reactions, as well as for molecular stability, most chemical concepts are not explicitly formulated on a diachronic basis. It will be argued here that a formulation explicitly incorporating temporal and epistemological considerations enables us to treat chemical reactions and chemical substances on ontologically equivalent terms, instead of assigning a more fundamental status to the latter. After all, in collision theory, a chemical substance is just a collision complex that takes too long. (...) How long qualifies as “too long”, and “too long” in relation to what, are crucial questions that distinguish chemical substances from chemical reactions, and reversible reactions from irreversible ones, thereby introducing anthropocentric considerations into these distinctions. Too long for a lab chemist is very different from too long for an astrochemist studying chemical reactions between chemical substances in inter-stellar space on cosmological timescales. Examining several physical and chemical properties on the basis of which chemical substances are distinguished from one another, the role of temporal and anthropocentric considerations in defining molecular properties is emphasized. I conclude with some observations on the much-debated reduction of chemistry to other disciplines, arguing that such reduction depends on our aesthetic choices as to what kinds of observations demand explanation, and what kinds of explanation are acceptable.

The concept of molecular structure is fundamental to the practice and understanding of chemistry, but the meaning of this term has evolved and is still evolving. The Born–Oppenheimer separation of electronic and nuclear motions lies at the heart of most modern quantum chemical models of molecular structure. While this separation introduces a great computational and practical simplification, it is neither essential to the conceptual formulation of molecular structure nor universally valid. Going beyond the Born–Oppenheimer approximation introduces new paradigms, bringing fresh (...) insight into the chemistry of fluxional molecules, proteins, superconductors and macroscopic dielectrics, thus opening up new avenues for exploration. But it requires that our ideas of molecular structure need to evolve beyond simple ball-and-stick-type models. (shrink)

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.

We identified nearly 180 Black women who earned medical degrees prior to the start of the Second World War and found information regarding their family and social connections, premedical and medical educations, and internship experience or lack thereof for many of these women. Through their collective history, we observed large-scale trends, especially regarding the importance of “separatist” medical education and declining medical school attendance among African American women in the 1910s as medicine became an increasingly exclusionary profession. While our research (...) uncovered trends specific to Black women physicians, the implications of our research can be applied far more widely to other historically marginalized scientific practitioners. This research reminds us of the longstanding and shifting presence of Black women in science and medicine, despite the enduring popular belief that white men represent who participates in science, both historically and today.

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.

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.

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)

Package downsizing is a practice where the package content is reduced without changing the package or the price of the product. In a market that is defined by ‘hyper-competition,’ package downsizing is often practiced by marketers to effect an invisible price increase for their products. Although marketers may maintain that providing, the legally required, quantity indication on the package is adequate for customers to make logical and informed choices, research indicates that consumers often do not consult quantity indications on packages (...) but use alternative methods (e.g., visual impressions of the package size, total package price, or previous purchase experience) to judge product quantity and to calculate product value. As a subtle means, package downsizing therefore has the potential to mislead customers in the buying process due to an unfavorable balance of information within the dyad. This could give rise to serious moral and ethical consideration. In this paper, we examined various issues related to package downsizing, such as why sellers resort to this type of practice, consumer vulnerability to package downsizing, as well as the extent of protection offered to consumers by the existing laws and regulations with respect to product packaging. Finally, we examined the ethics of package downsizing using the existing legal, moral, and professional ethical standards as well as the principle of equivalence. Our analysis indicates that package downsizing, as it is practiced by the marketers and sellers today, is unethical as far as the consumers are concerned. (shrink)
