The Experiments of Ramón M. Termeyer SJ on the Electric Eel in the River Plate Region (c. 1760) and other Early Accounts of Electrophorus electricus

Dr. Haakon Sæthre was a leader of Norwegian neurology and psychiatry. He was resourceful, compassionate and had immense pride in his independent homeland. He described Sæthre-Chotzen syndrome (acrocephalosyndactyly type III). When Nazi Germany occupied Norway during World War II, Sæthre fearlessly and actively resisted, from revoking his medical association membership, to hiding persecuted Jews as patients in his psychiatric ward and aiding in their escape to Sweden, to managing the largest “illegal” food warehouse in Oslo with Danish humanitarian aid. As a prominent and noticeable citizen, he was arrested and executed by the Nazis in reprisal for the resistance's assassination of a hated Norwegian Nazi. His legacy lives on in Norway, where he was honored by a scholarship fund, a portrait and multiple plaques at Ullevål Hospital, and a street and memorial statue in his hometown. He was a hero and should be remembered by all who practice neurology.     

A History of the Concept of the Stimulus and the Role it Played in the Neurosciences

The term stimulus, as it was used in science from its earliest appearance in the sixteenth century up to the beginning of the nineteenth century, shows a gradual progress in denotation from the physical object designed to produce nervous and muscular excitation to the generically conceived event or object that initiates sensory or motor activity. To this shift corresponds a shift in the understanding of sensory experience. Johannes Müller's law of specific energy of sensory nerves played a major role in the shift, and Hermann von Helmholtz gave the shift its most thorough philosophical explanation.     

Confabulations: A Conceptual History

Confabulations are inaccurate or false narratives purporting to convey information about world or self. It is the received view that they are uttered by subjects intent on ‘covering up’ for a putative memory deficit. The epidemiology of confabulations is unknown. Speculated causes include amnesia, embarrassment, ‘frontal lobe’ damage, a subtype of ‘personality’, a dream-like event, and a disturbance of the self. Historical analysis shows that ‘confabulation’ was constructed at the turn of the century as part of a network of concepts (e.g. delusion, fixed idea, etc.) Meant to capture narratives with dubious content. This paper deals with the history of the construction of the word and concept of confabulation and with earlier recognitions of the behaviours that serve as their referent and puts forward a model based on historical data. Two phenomena are included under ‘confabulation’: ‘untrue’ utterances by subjects with memory impairment and ‘fantastic’ utterances marshalled with conviction by subjects suffering from psychoses and no memory deficit. Under different disguises, the ‘covering up’ or ‘gap filling’ hypothesis is still going strong. Although superficially plausible, it poses problems in regards to the issue of ‘awareness of purpose’: if full awareness is presumed, then it is difficult to differentiate confabulations from lying; if no awareness is presumed then the semantics of the concept of ‘purpose’ is severely stretched and confabulations cannot be differentiated from delusions. The received view of confabulations also neglects the clinical observation that confabulations (particularly provoked ones!) Do occur in dialogical situations: i.e., the manner of the asking may increase their probability. It is suggested here that confabulations are a disorder of a putative narrative function which is also found in ‘normal’ subjects. It is also hypothesized that this trait is normally distributed in the population. In the absence of adequate epidemiological information, research efforts should be directed at mapping the distribution of this narrative (or confabulatory) capacity in the community at large. Only then it will be possible to understand the significance of its disorders. In the long term, this approach will prove more heuristic than unwarranted speculation based on few anecdotal cases.

Interrogating Power: Engaged Energy Anthropology

Human-induced global threats are compelling many anthropologists to rethink roles, methods, and paradigms and engage in public debate and action on energy policies, extraction processes, commodity chains, and consumption. Laura Nader's Energy Reader embodies her decades-long engagement as a catalyst for public debate on U.S. energy issues. Tanja Winther's Impact of Electricity exemplifies ethnography informing development practice. Strauss and colleagues’ Cultures of Energy reflects diverse approaches seeking to build cultural understandings to inform energy choices. There remains a need for collaboration with anthropologists embedded in energy-related agencies—positioned where they can leverage anthropological knowledge to push policy envelopes.     

Oskar von Miller and the Art of the Electrical Exhibition: Staging Modernity in Weimar Germany

Within the larger framework of understanding how modernity wasframed within and through the domestic sphere, this articleconsiders the efforts of Bavarian electrical engineer Oskarvon Miller to electrify and modernize Germany against the backdropof Weimar reform movements. Unlike modernist reformers associatedwith such projects as the Bauhaus or the Werkbund, Miller wasa practical systems-builder who sought to encourage consumptionwithin traditional frameworks of home and Heimat. For Miller,exhibiting the benefits of technology was a key element in securingits success, and his reliance on consumers rested on a corporatistideal that would create a new kind of community centred on technology.Whereas in the Imperial era Miller focused on Handwerker andsmall machines as the guarantors of both progress and socialstability, in the Weimar era he turned to housewives and housework.Through his involvement in electrification schemes as well asin his work in founding the Deutsches Museum, one of the firstmuseums of science and technology in Europe, Miller createda powerful narrative of technological progress that was bothtraditional and modern.     

Functional specialization across space: a case study of the Canadian Electricity Industry, 1971–2001

This article examines the location of functions within the electricity sector in Canada from 1971 to 2001, using a centre‐periphery model. Power generation, distribution and retailing are generally carried out by multiestablishment crown corporations. Location patterns of different functions—management, scientific, production, etc.—are analyzed via the use of occupational groups. The spatial distribution of functions is found to be generally consistent with centre‐periphery relationships, with evidence of a growing functional specialization between large metropolitan and nonmetropolitan locations. However, differences emerge depending on power generation sources: fossil fuels, hydro, nuclear, solar or biomass. The choice of a power generation source has consequences for local economies.     

Animal Electricity at the End of the Eighteenth Century: The Many Facets of a Great Scientific Controversy

In the 1790s, Luigi Galvani and Alessandro Volta were the main protagonists of a lively debate on the role of electricity in animal organisms. Significant developments originated from this debate, leading to the foundation of two new disciplines, electrodynamics and electrophysiology, that were to play a crucial role in the scientific and technological progress of the last two centuries. The Galvani-Volta controversy has been repeatedly reconstructed, sometimes in an attempt to identify the merits and the errors of one or the other of the two protagonists, sometimes with the aim of demonstrating that the theories elaborated by the two Italian scholars were irreconcilable, reflecting completely different ways of looking at phenomena and conceiving of scientific research. In this article a different interpretation is offered, based on a discussion of the scientific issues that were central to Galvani's and Volta's research, and with reference to the context of science and society of the eighteenth century.     

Laboratory Notes,Laboratory Experiences,and Conceptual Analysis: Understanding the Making of Ohm's First Law in Electricity

Georg Simon Ohm's work in the field of electricity led to what is now considered to be the most fundamental law of electrical circuits, Ohm's Law. Much less known is that only months earlier, Ohm had published another law—one that differed significantly from the now accepted one. The latter entailed a logarithmic relation between the length of the conductor and a parameter that Ohm called “loss of force.” This paper discusses how Ohm came up with an initial law that he felt compelled to correct a few months later. We analyze Ohm's publication as well as his laboratory notes, relating them to our own laboratory experiences while using the replication method to study his work. We also discuss the conceptual background of Ohm's work. We conclude that he was significantly influenced by French studies in the field of electricity, most notably the ones by Charles Augustin Coulomb.
