Language as a mechanism for reasoning about possibilities

The ability to entertain and reflect on possibilities is a crucial component of human reasoning. However, the origin of this reasoning-whether it is language-based or not-is highly debated. We contribute to this debate by investigating the relation between language and thought in the domain of possibility from a developmental perspective. Our investigation focuses on disjunctive syllogism, a specific type of possibility reasoning that has been explored extensively in the developmental literature and has clear linguistic correlates. Seeking links between conceptual and linguistic representations, we review evidence on how children reason by the disjunctive syllogism and how they acquire logical and modal language. We sketch a proposal for how language and thought interact during development. This article is part of the theme issue 'Thinking about possibilities: mechanisms, ontogeny, functions and phylogeny'.

Possibilities and challenges in digital personal identification using teledentistry based on integration of telecommunication and dental information: a narrative review

Personal identification using dental evidence is decisive in the case of unidentified bodies because dental features, including decayed, missing and filled teeth, are unique to every individual. This review explored the possibilities and problems associated with personal identification through digital methods by the integration of telecommunications and dentistry, also known as teledentistry. Establishment of a global, objective personal identification method using dental evidence through teledentistry is desirable. However, the review reports that there are various problems that need to be resolved first, in aspects such as changes in dentition over time, technology, individual privacy and ethics. It is suggested that solving such problems and constructing a worldwide dental database for personal identification from dental images, using teledentistry, as part of social services, is a new challenge for researchers in forensic odontology and dentistry.

Challenges and possibilities of developing cardiac surgery in a peripheral hospital of low- and middle-income countries

OBJECTIVE

Over a million cardiac surgeries are performed every year around the globe. However, approximately 93% of world population living in low- and middle-income countries have no access to cardiac surgery. The incidence of rheumatic and congenital heart disease is high in Nepal, while only 2,500-3,000 cardiac surgeries are performed annually. The aim of our study is to analyze challenges and opportunities of establishing a cardiac surgery program in a peripheral hospital of Nepal.

METHODS

We analyzed our effort to establish a cardiac surgery program in a peripheral hospital in Nepal.

RESULTS

Out of 2,659 consulted and diagnosed patients, we performed 85 open-heart surgeries in 4 years. Mean age of patients was 38.35 ± 14.13 years. The majority of patients were male (62.4% of patients) with 65.9% suffering from rheumatic heart disease. Average intensive care unit stay and hospital stay were 2.32 ± 1.1 and 8.29 ± 2.75 days, respectively. No in-hospital mortality was observed.

CONCLUSION

We conclude that developing cardiac surgical care in a peripheral hospital of a developing country is feasible with support from government, foreign colleagues, local teams, and non-governmental organizations. The availability of a regular cardiac surgery service in the periphery of the country makes such services more accessible for the patients and helps in reducing the long waiting lists and unmanageable workload in the established cardiac centers in the capital city.

Depression, possibilities, and competence: a phenomenological perspective

Competent decision-making is required for informed consent. In this paper, I aim, from a phenomenological perspective, to identify the specific facets of competent decision-making that may form a challenge to depressed patients. On a phenomenological account, mood and emotions are crucial to the way in which human beings encounter the world. More precisely, mood is intimately related to the options and future possibilities we perceive in the world around us. I examine how possibilities should be understood in this context, and how, in depression, decision-making might be compromised. I suggest that, based on this analysis, a specific emphasis and alertness in assessments of competence in depressed patients is called for. In fact, close attention should be paid to the range of future possibilities depressed patients are able to perceive. In addition, providing environmental cues to these patients might be one way of enhancing their decision-making capacity. The practical suggestions arrived at are open to empirical research.
