Roger Abrahams, author
No full textRoger Abrahams, director of the African and Afro-American Research Institute at the University of Texas-Austin and author of Positively Black, argues the case for ethnic diversity in this interview. He also discusses that the idea of "new ethnicity" is not restricted to black or brown America and he sees a widespread return to old mores inherent in the traditional ethnic value system. Interviewed by WTMJ-TV host Jim Peck.GrayscaleSoun

For and against; should doctors advise young people to abstain from sex?
No full textAgainst a background of high rates of teenage pregnancy and an increasing prevalence of sexually transmitted infections, the sexual conduct of young people is vigorously debated. Many teenagers later say that they had sexual intercourse "too early" but should doctors be advising young people to abstain from sex? Trevor Stammers, who is a tutor in general practice and an author and broadcaster on sexual health, and Roger Ingham, who has done research on sexual conduct and sex education in Britain and other countries, consider whether advising abstinence is an effective response to declining teenage sexual health
Impossibility of superluminal signalling in Minkowski space-time does not rule out causal loops
Get PDFCausality is fundamental to science, but it appears in several different
forms. One is relativistic causality, which is tied to a space-time structure
and forbids signalling outside the future. A second is an operational notion of
causation that considers the flow of information between physical systems and
interventions on them. In [Vilasini and Colbeck, Phys. Rev. A. 106, 032204
(2022)], we propose a framework for characterising when a causal model can
coexist with relativistic principles such as no superluminal signalling, while
allowing for cyclic and non-classical causal influences and the possibility of
causation without signalling. In a theory without superluminal causation, both
superluminal signalling and causal loops are not possible in Minkowski
space-time. Here we demonstrate that if we only forbid superluminal signalling,
superluminal causation remains possible and show the mathematical possibility
of causal loops that can be embedded in a Minkowski space-time without leading
to superluminal signalling. The existence of such loops in the given space-time
could in principle be operationally verified using interventions. This
establishes that the physical principle of no superluminal signalling is not by
itself sufficient to rule out causal loops between Minkowski space-time events.
Interestingly, the conditions required to rule out causal loops in a space-time
depend on the dimension. Whether such loops are possible in three spatial
dimensions remains an important open question.Comment: 4+4 pages. This work is based on the framework of arXiv:2109.12128,
