The third additive term refers to the continuous change in the weight of the rocket as its fuel is consumed. On the other side of the equal sign, R is the distance from the rocket to the Earth’s centre; β the angle between the local horizontal and the direction of flight, δ a velocity ratio (Moore, 1987: 173).
ellauri066.html on line 360: Is Pynchon’s equation of motion a standard differential equation used by specialists to calculate the path of a rocket’s flight or to control its yaw? No: Pynchon’s equation does not resemble anything one might reasonably expect. […] Not only are most of the symbols in Pynchon’s equation obscure, but the general structure of the terms in the equation also makes it impossible to identify with one or other of the equations describing the position and orientation of a rocket in flight. This equation, then, is not a genuine mathematical expression in this context. It may appear authoritative to the layperson, but it is unlikely to fool a rocket scientist.

ellauri100.html on line 159: Based on a detailed study of frontal, dorsal and lateral photographs of 4000 male subjects of college age, a 3 dimensional scheme for describing human physique is formulated. Kretschmer´s constitutional typology is discarded in favor of one based on 3 first order variables or components, endomorphy, mesomorphy, and ectomorphy, each of which is found in an individual physique and indicated by one of a set of 3 numerals designating a somatotype or patterning of these morphological components. Seventy-six different somatotypes are described and illustrated. These somatotypical designations are objectively assigned on the basis of the use of 18 anthropometric indices. Second-order variables also isolated and studied are dysplasia, gynandromorphy, texture and hirsutism. Historical trends in constitutional research are summarized. A detailed description is given of the development of the somatotyping technique combining anthroposcopic and anthropometric methods. Reference is made to somatotyping with the aid of a specially devised machine. Topics discussed include: the choice of variables, morphological scales, a geometrical representation of somatotypes, the independence of components, correlational data, the problem of norms, the modifiability of a somatotype, hereditary and endocrine influences and the relation of constitution to temperament, mental disease, clinical studies, crime and delinquency, and the differential education of children. Descriptive sketches of variants of the ectomorphic components are given. Appendices list tables for somatotyping and a series of drawings of 9 female somatotypes. An annotated bibliography is followed by a more general one. 272 photographs and drawings illustrate the somatotypes. (PsycINFO Database Record (c) 2016 APA, all rights reserved)

Die so beschriebenen Profilkategorien wirken aber am Ende so überladen, beliebig und disparat, dass es schwerfällt, damit eine präzise differentialdiagnostische Abgrenzung der narzisstischen Persönlichkeitsstörung mit Hilfe ihrer klinischen Merkmale zu leisten. So führt Akhtar etwa unter der Kategorie ‘Interpersonale Beziehungen/verdeckt’ das skurrile Merkmal ein: „Tendenz, Briefe nicht zu beantworten“ oder unter derselben Kategorie/sichtbar die schwer operationalisierbare : „Unfähigkeit, wirklich authentisch (Hervorhebung von mir, M.A.) an Gruppenaktivitäten teilzunehmen“.
ellauri147.html on line 814: Eine psychoanalytische Prozessdiagnostik geht anders vor. In der therapeutischen Situation des Übertragungs-Gegenübertragungsgeschehen, können wir den Narzissmus und seine Störung erspüren. Die differentialdiagnostisch relevanten suggestiven Mitteilungen lauten:
ellauri147.html on line 831: Bei Zweifeln an der Anerkennung oder ihrer Verweigerung entstehen Gefühle der Missachtung. In einem unbewusst inszenierten Kampf um Anerkennung werden dann Ansprüche ausgetragen, die in den differentialdiagnostischen Symptombeschreibungen der narzisstischen Störung als „Beachtung suchen“, „Aufmerksamkeit verlangen“ oder „Bewunderung fordern“, als „narzisstische Wut“ oder „narzisstischer Rückzug“ imponieren. Es sind intersubjektive Leitsymptome, in denen sich das bedrohte Selbst, seine Abhängigkeit verleugnend, fordernd an oder aggressiv gegen das Objekt richtet – oder sich von ihm völlig abwendet und in den begleitenden Phantasien (um nicht zu sagen: im Unbewussten) das Objekt umso stärker festhält. -->

But that´s impossible, because happiness is a differential: everyone must have more than the others and more than before. Everyone just can't have that, it's a logical contradiction.
ellauri285.html on line 759: Fredrickson wrote a response in which she conceded that the mathematical aspects of the critical positivity ratio were "questionable" and that she had "neither the expertise nor the insight" to defend them, but she maintained that the empirical evidence for the existence of a critical positivity ratio was solid. Brown, Sokal, and Friedman, the rebuttal authors, published their response to Fredrickson´s "Update" the next year, maintaining that there was no evidence for a critical positivity ratio. Losada declined to respond to the criticism (indicating to the Chronicle of Higher Education that he was too busy running his consulting business).[verification needed] Hämäläinen and colleagues responded later, passing over the Brown-Sokal-Friedman rebuttal claim of failed criteria for use of differential equations in modeling, instead arguing that there were no fundamental errors in the mathematics itself, only problems related to the model´s justification and interpretation.
ellauri285.html on line 763: Building on research by Barbara Fredrickson suggesting that individuals with a higher ratio of positive to negative emotions tend to have more successful life outcomes, and on studies by Marcial Losada applying differential equations from fluid dynamics to human emotions,[citation needed] Fredrickson and Losada proposed as informative a ratio of positive to negative affect derived from nonlinear dynamics modelling (based on Lorenz systems), which appeared in 2005 in a paper in American Psychologist. The derived combination of expressions and default parameters led them to conclude that a critical ratio of positive to negative affect of exactly 2.9013 separated flourishing from languishing individuals, and to argue that the ideal positivity/negativity ratio lies between 2.9013 and an upper limit ratio of 11.6346. Hence, they claimed that their model predicted cut-off points for the minimum and maximum positivity ratios within which one should observe qualitative changes in an individual´s level of flourishing, specifically, that those within this range of ratios would "flourish", and those outside would "languish".[non-primary source needed] As of January 2014, the 2005 Fredrickson and Losada´s paper had been cited more than 320 times in the psychology literature.
ellauri285.html on line 766: the data used by Losada in several analyses do not meet basic criteria for the use of differential equations (such as the use of continuous variables that evolve smoothly and deterministically over time);
ellauri285.html on line 768: differential equations used by Losada to calculate the critical positivity ratio use parameters taken directly from Lorenz´s simplified, illustrative, and arbitrary models for fluid dynamics, with Losada giving no rationale for his choice of parameters;
xxx/ellauri113.html on line 480: Berlinski has written works on systems analysis, the history of differential topology, analytic philosophy, and the philosophy of mathematics. Berlinski has authored books for the general public on mathematics and the history of mathematics. These include The Secrets of the Vaulted Sky (2003), aimed to redeem astrology as "rationalistic"; Publishers Weekly described the book as offering "self-consciously literary vignettes ... ostentatious erudition and metaphysical pseudo-profundities".
