TACHYCARDIA MISDIAGNOSED AS PSYCHOTIC MENTAL ILLNESS.

Many people with similar or related life challenges may decide not to share personal information of the kind described in the present memoir. My sharing is intended in defense of my cognitive salience: despite having been diagnosed as supposedly “psychotic.” It is my hope that this memoir might help tip the scales in favor of “psycho-social” rather than “in-your-head,” models of personality disorder (1, 2, 3). Superior psychological models can be found (4); even before the gross statistics of Charles Spearman (1863 to 1945), AND before the forced conditioning experimentations of Ivan Pavlov (1849 to 1936), AND as well before the dubious Oral-Anal Hypothesis of Sigmund Freud (1856 to 1939). Some of these models (4) were presented by names such as Francis Galton (1822 to 1911), Hermann von Helmholtz (1821 to 1894), and Wilhelm Wundt (1832 to 1920): leaders of the subject area-domains commonly referred to as Experimental Psychology and Sensory Physiology.

P1846HISTORY OF ARTIFICIAL INTELLIGENCE AND ITS APPLICATION IN NEPHROLOGY

Background and Aims The application of artificial intelligence and neural networks in medicine is used to help solve problems that cannot be handled by the classical approach. The common name “cybernetics” encompassed the fields of management, information technology and biomedicine, but these disciplines continued to evolve independently due to the explosion of new knowledge. Over time, the development of neural networks has been turbulent and is now widely used in various fields of medicine and even in nephrology. The aim of the paper is to analyze the history of the development of artificial intelligence and its application in nephrology. Method Data were collected from books, magazines, encyclopedias and databases. Results Basic research on cybernetics and medicine was done by Golgi and Kelley doctors after Isaak Newton and Hermann von Helmholtz. The first theoretical mathematical models were derived in 1943 by Warren Mc Culloch and Walter Pitts. A few years later, a more contemporary contribution to the development of neural networks was given by Norbert Wiener and John von Neumann because they thought that research into biomedicine based on human brain function would be very interesting. In addition, in 1948 Norbert Wiener was the first to publish a work explaining the term cybernetics. At that time, the first experiments were made and new theories in the field of artificial intelligence were put forward by Marvin Misnki. The first training of neurons and the basis of all methods for training neurons was described by the Canadian Donald O Hebb. After the first successful neurocomputer in 1957, on which Rosenblatt worked, scientists have perfected various models of neural networks to this day. So far, mostly retrospective studies have been done in clinical nephrology, transplantation and dialysis with the help of algorithms used in neural networks. Particularly complex nephrologic patient relationships as well as assistance with timely implementation of new good clinical practice guidelines, patient prediction in at least the next month, and patient selection for palliative care are just some segments in nephrology that require the introduction of such tools into daily clinical practice with the aim of sensitive patient populations have better treatment outcomes, with physicians having more comprehensive insight and control over the mass of data. Conclusion Today‘s application of artificial intelligence in nephrology is based on retrospective research. The dizzying rise in technological development so far will allow the use of cybernetics and available tools based on neural network algorithms to enable and improve the nephrologists’ dedication and effectiveness.

Printing Piano Pedagogy: Experimental Psychology and Marie Jaëll's Theory of Touch

In her 1899 pedagogy manual Touch: Piano Instruction on the Basis of Physiology, the composer and pianist Marie Jaëll (1846–1925) describes pianistic touch as a ‘polyphony of sensations’, a synthesis of vibrations that is both physical and psychical. This article examines Jaëll's recourse to nineteenth-century experimental science, specifically experimental psychology, to develop a theory of pianistic touch. Touch, Jaëll contends, necessitates a pianist's attention to haptic and aural impulses in an elusive, ‘simultaneous and successive’ process that collates the pianist's tangible sensation of the keyboard and the ineffable mental impressions conjured by sound. This braided sense of musical touch can be cultivated in performers and transmitted to listeners. Jaëll makes this assertion using a novel kind of visual evidence: fingerprints. Fingerprinting her students before and after the execution of selected piano études and treating the prints as diagnostic documents, Jaëll posits that isolating and attending to minute variations in touch is akin to attuning to the aesthetic content of a musical work. Jaëll crystallized her methodology in a vibrant collaboration with Charles Féré (1852–1907), a criminologist and one-time student of Jean-Martin Charcot. More broadly, Jaëll's treatise is a striking exponent of the era's ‘graphical method’, pioneered by Étienne-Jules Marey, which sought to supplant scientific rhetoric with ‘objective’ truth, depicted as machine-generated wave forms. The ethos that motivated the creation of such representations, propagated by an array of influential scientists including Ernst Heinrich Weber and Hermann von Helmholtz, underscores a tendency to intertwine physiology and psychology in an enterprise that quantified sensation as a fact of mechanistic causes. Jaëll's emphasis on attention – how thought modifies touch and sound – sets her theory apart from experimental psychology's more determinist premises. In Jaëll's experimental apparatus, fingerprints are not objective; rather, they index the variable haptic and sonic sensations experienced by the pianist. As a nascent theory of embodied cognition, Jaëll's pedagogy bespeaks a fluid relationship between mind and body at the dawn of the twentieth century.

William Thomson (Lord Kelvin)

Being raised on the caloric theory in which heat is a conserved quantity, Thomson faced challenges in accepting Clausius’ analysis of Carnot’s heat engine. Once he finally overcame these challenges, helped by collaborating with his brother James, Thomson accepted and then furthered Clausius’ work by proposing a different perspective of Clausius’ 2nd Principle and the 2nd Law of Tthermodynamics: energy dissipation. This chapter concludes with the role Hermann von Helmholtz played in bringing a rational approach to a thermodynamic science based on cause–effect.
