Scanning Tunneling Thermometry
No full textThe best spatial resolution so far achieved in thermal imaging is several nanometers, much coarser than routinely achieved for other physical properties. Here we propose a method to map electronic temperature variations in operating nanoscale conductors by relying solely upon electrical tunneling current measurements. The proposed measurement scheme involves two scanning probe operations to measure the conductance and thermopower, respectively. These two measurements are shown to determine the local temperature with high accuracy in nanoscale conductors, where the Wiedemann-Franz law holds quite generally. The proposed scanning tunneling thermometer, owing to its operation in the tunneling regime, would be capable of mapping temperature variations with subnanometer resolution, thereby enhancing the resolution of scanning thermometry by some 2 orders of magnitude.This item from the UA Faculty Publications collection is made available by the University of Arizona with support from the University of Arizona Libraries.

Concerning Expressions in the Opening Scene of MON : The Novelist’s Techniques and Attitudes Found in Expressive Distance
No full textThis paper deals with novelist SOSEKI’s techniques and attitudes, by analyzing the sentence structure in the first scene of MON. I have used “The Theory of Expressive Distance”, Chapter 8 of the volume four of The Theory of Literature (1907, 5), and recent theories of space in linguistic expression. Two problems are clarified: (1) The author places the time of the first scene six years after the principal occurrence of the novel. (2) Even though in the first scene Sosuke, who has stolen his friend’s wife and is obsessed with a sense of guilt, begins to doubt the way he is dealing with his sin, he doesn’t act to achieve real redemption or personal salvation. The author, therefore, intervenes in Sosuke’s inner life, freely changing the special point of reference. This paper elucidates the use of these two operations, by which the author constructs the characters in the story and develops the plot.departmental bulletin pape

Testing the Intrinsic Benefit Model of the Signaling Theory
No full textThis study proposes the intrinsic benefit model of the signaling theory for sociology. The signaling theory is a subtheory of the game theory. It was developed independently within Evolutionary Biology and Economics, and it is concerned with the communications under the situations with asymmetrical information. Although the signaling theory have been widely adapted across social science, its influence within Sociology has been limited so far. This study proposes the argument that the signaling theory can achieve the increased relevance within Sociology by focusing on the role of (perceived) intrinsic benefit obtained from the signal production. The focus on the intrinsic benefit would allow the signaling theory to be applied on the broader range of phenomena which are of sociological interests, while at the same time analytically integrating additional social and symbolic contexts of the signals. Based on this argument, the propositions were developed about the role of the signal visibility and the intentionality of the signal. The three experiments were conducted to test the propositions. The two vignette experiments were conducted to test the effect of signal visibility on the signaling of environmental commitment through the purchases of electronic vehicles. A laboratory experiments was conducted to test the effect of the intentionality of the signal on the signaling of trustworthiness through donations. The first experiment gave the strong support to the propositions, whereas the second and the third experiment produced the mixed results. The author suggests that the overall findings are consistent with the main argument underlying the intrinsic benefit model
