Empathy, caring and compassion: Toward a Freudian critique of nursing work
Nursing Philosophy, Volume 24, Issue 1, January 2023., 2023 Abstract The aim of this paper is to summarize key psychoanalytic concepts first developed by Sigmund Freud and apply them to a critical exploration of three terms that are central to nursing's self‐image—empathy, caring, and compassion. Looking to Menzies‐Lyth's work, I suggest that the nurse's strong identification as a carer can be understood as a ...

Instanton effects in rank deformed superconformal Chern-Simons theories from topological strings [PDF]
, 2017 A bstractIn the so-called (2, 2) theory, which is the U(N)4 circular quiver superconformal Chern-Simons theory with levels (k, 0, −k, 0), it was known that the instanton effects are described by the free energy of topological strings whose Gopakumar-Vafa

Layer construction of 3D topological states and string braiding statistics [PDF]
Phys. Rev. X 4, 041043 (2014), 2014 While the topological order in two dimensions has been studied extensively since the discover of the integer and fractional quantum Hall systems, topological states in 3 spatial dimensions are much less understood. In this paper, we propose a general formalism for constructing a large class of three-dimensional topological states by stacking layers of ...

Constructing Spin Density Vector Twists With Spin Density Singularity
IEEE Photonics Journal, 2022 In this article, we propose a non-orbital angular momentum (OAM) method for constructing the spiral twists of spin density (SD) vectors in three-dimensional (3D) optical fields. This is realized by generating strings of SD singularities in a longitudinal

Topological strings on singular elliptic Calabi-Yau 3-folds and minimal 6d SCFTs [PDF]
, 2017 A bstractWe apply the modular approach to computing the topological string partition function on non-compact elliptically fibered Calabi-Yau 3-folds with higher Kodaira singularities in the fiber.

JHEP 0609:082,2006, 2005 We classify potential cosmic strings according to the topological charge measurable outside the string core. We conjecture that in string theory it is this charge that governs the stability of long strings. This would imply that the SO(32) heterotic string can have endpoints, but not the E_8 x E_8 heterotic string.

Spectral sequences in string topology [PDF]
Algebraic & Geometric Topology, 2011 In this paper, we investigate the behaviour of the Serre spectral sequence with respect to the algebraic structures of string topology in generalized homology theories, specificially with the Chas-Sullivan product and the corresponding coproduct and module structures. We prove compatibility for two kinds of fibre bundles: the fibre bundle $ ^n M \to L^

Charged Black Cosmic String [PDF]
, 1997 Global U(1) strings with cylindrical symmetry are studied in anti-de Sitter spacetime. According as the magnitude of negative cosmological constant, they form regular global cosmic strings, extremal black cosmic strings and charged black cosmic strings ...

Dirichlet Topological Defects [PDF]
, 1997 We propose a class of field theories featuring solitonic solutions in which topological defects can end when they intersect other defects of equal or higher dimensionality.
