DSRP Theory is now over 25 years old with more empirical evidence supporting it than any other systems thinking framework. Yet, often misunderstood and described in ways that are inaccurate. describes four patterns their underlying elements—identity (i) (o) for Distinctions (D), part (p) whole (w) Systems (S), action (a) reaction (r) Relationships (R), point (ρ) view (v) Perspectives (P)—that universal both cognitive complexity (mind) material (nature). provides a basis or as well (systems science). This paper, relatively short primer on the theory, clarity to those wanting understand its implications.

Wolfram syndrome (WS) is a rare genetic disease characterized by diabetes, optic atrophy and deafness. Patients die at 35 years of age, mainly from respiratory failure or dysphagia. Unfortunately, there no treatment to block the progression symptoms an urgent need for adequate research models. Here, we report on phenotypical characterization two loss-of-function zebrafish mutant lines: wfs1aC825X wfs1bW493X. We observed that wfs1a deficiency altered size ear retina fish. also documented decrease in expression level unfolded protein response (UPR) genes basal condition stress condition, i.e. after tunicamycin treatment. Interestingly, both mutants lead their visual function measured behaviorally. These deficits were associated with UPR conditions. basal, ATP-linked maximal mitochondrial respirations transiently decreased wfs1b mutant. Taken together, these lines highlight critical role UPR, physiology. models will be useful tools better understand cellular Wfs1 develop novel therapeutic approaches WS.

This paper posits that universal atomic elements exist underlie complex cognition. At its core, constructs are born of the dynamics thinking operating on information. elemental understanding structural underpinnings - and between among provides insight into value awareness one’s to everyday life scientific inquiry. Knowledge dynamical properties human thought leads generative, purposeful, predictive cognitive acts evolve thinking. As a result, our mental models (comprised information thinking) how systems work better aligned with they in real world. alignment yields solutions, innovation results. Continued inquiry universality these has significant potential advance across wide variety academic disciplines. In other words, study cognition is deemed synonymous evolution science knowledge itself.
