A Personal Perspective on Daily Occupations to Counteract Cancer Related Fatigue: A Case Study
Background: This case study aimed to identify and describe meaningful physical occupations used by a cancer survivor to increase or maintain levels of participation during active chemotherapy and subsequent cancer related fatigue.
Method: A case study approach was used to develop an in-depth description and analysis based on one participant’s experience with breast cancer and associated treatments. A semi-structured interview was conducted. The data were analyzed through description of the case, categories, and themes. It also included categorical aggregation in efforts to seek a collection of instances from the data to explore any issue-relevant meanings.
Results: Following data analysis, one overarching theme, return to normalcy, was identified with three subthemes: (a) prioritization of meaningful activities, (b) modifications to activities or routines, (c) lack of referral for immediate needs.
Conclusion: Personal knowledge of occupational therapy practice provided support for enhancing engagement in daily meaningful occupations. Lessons learned from this experience could be applied to clients experiencing cancer related side effects to improve engagement in daily occupations
Local triple derivations on real C*-algebras and JB*-triples
We study when a local triple derivation on a real JB*-triple is a triple
derivation. We find an example of a (real linear) local triple derivation on a
rank-one Cartan factor of type I which is not a triple derivation. On the other
hand, we find sufficient conditions on a real JB*-triple E to guarantee that
every local triple derivation on E is a triple derivation
Single atom edge-like states via quantum interference
We demonstrate how quantum interference may lead to the appearance of robust
edge-like states of a single ultracold atom in a two-dimensional optical
ribbon. We show that these states can be engineered either within the manifold
of local ground states of the sites forming the ribbon, or of states carrying
one unit of angular momentum. In the former case, we show that the
implementation of edge-like states can be extended to other geometries, such as
tilted square lattices. In the latter case, we suggest to use the winding
number associated to the angular momentum as a synthetic dimension.Comment: 5 pages, 5 figure
2-local triple homomorphisms on von Neumann algebras and JBW-triples
We prove that every (not necessarily linear nor continuous) 2-local triple
homomorphism from a JBW-triple into a JB-triple is linear and a triple
homomorphism. Consequently, every 2-local triple homomorphism from a von
Neumann algebra (respectively, from a JBW-algebra) into a C-algebra
(respectively, into a JB-algebra) is linear and a triple homomorphism
Local triple derivations on C*-algebras
We prove that every bounded local triple derivation on a unital C*-algebra is
a triple derivation. A similar statement is established in the category of
unital JB*-algebras.Comment: 12 pages, submitte
The Indubitable Nature of Temporality in Perception
The flow of time is vital for perception. While philosophers disagree as to the nature of how time is represented, i.e. that the passage of time is that of mere tense or belonging to the nature of the experience, it is generally accepted that the represented somehow tells us about the future, present and past. My contention is that this temporal character is indubitable for perception. I will begin by providing a temporal model of how percepts are represented. After giving a detailed presentation of the model, some problems will be considered, namely that the temporal model is doomed by the reversal of causal relata or no different than an unsuccessful perceptual experience. My contention will be that what is being represented in perception possesses fundamental temporal qualities that are indubitable for the experience, regardless of metaphysical worries or perceptual worries. If such temporal qualities belonging to the represented go without say, then a question remains as to the status of the temporal character of perception. After contrasting Kant’s position with Husserl’s position on the status of temporality in perception, I will argue that Kant’s position on perceptual temporality as manifesting from a cognitive faculty is more plausible
