TL;DR: The authors analyzes competitive markets in which the characteristics of the commodities exchanged are not fully known to at least one of the parties to the transaction, and suggests that some of the most important conclusions of economic theory are not robust to considerations of imperfect information.
Abstract: Economic theorists traditionally banish discussions of information to footnotes. Serious consideration of costs of communication, imperfect knowledge, and the like would, it is believed, complicate without informing. This paper, which analyzes competitive markets in which the characteristics of the commodities exchanged are not fully known to at least one of the parties to the transaction, suggests that this comforting myth is false. Some of the most important conclusions of economic theory are not robust to considerations of imperfect information.

TL;DR: In this paper, the development of statistical methods at Rothamsted Experimental Station by Sir Ronald Fisher is used to illustrate these themes, and the authors discuss the importance of flexibility to profit from such confrontations and to devise parsimonious but effective models.
Abstract: Aspects of scientific method are discussed: In particular, its representation as a motivated iteration in which, in succession, practice confronts theory, and theory, practice. Rapid progress requires sufficient flexibility to profit from such confrontations, and the ability to devise parsimonious but effective models, to worry selectively about model inadequacies and to employ mathematics skillfully but appropriately. The development of statistical methods at Rothamsted Experimental Station by Sir Ronald Fisher is used to illustrate these themes.

TL;DR: In this paper, the delta-Eddington approximation was used to calculate monochromatic radiative fluxes in an absorbing-scattering atmosphere, by combining a Dirac delta function and a two-term approximation, which overcomes the poor accuracy of the Eddington approximation for highly asymmetric phase functions.
Abstract: This paper presents a rapid yet accurate method, the “delta-Eddington” approximation, for calculating monochromatic radiative fluxes in an absorbing-scattering atmosphere. By combining a Dirac delta function and a two-term approximation, it overcomes the poor accuracy of the Eddington approximation for highly asymmetric phase functions. The fraction of scattering into the truncated forward peak is taken proportional to the square of the phase function asymmetry factor, which distinguishes the delta-Eddington approximation from others of similar nature. Comparisons of delta-Eddington albedos, transnmissivities and absorptivities with more exact calculations reveal typical differences of 0–0.022 and maximum differences of 0.15 over wide ranges of optical depth, sun angle, surface albedo, single-scattering albedo and phase function asymmetry. Delta-Eddington fluxes are in error, on the average, by no more than 0.5%0, and at the maximum by no more than 2% of the incident flux. This computationally fa...

TL;DR: Narcotic analgetics administered directly into the spinal subarachnoid space of the rat via a chronically inserted catheter produce a potent analgesia that can be antagonized by naloxone.
Abstract: Narcotic analgetics administered directly into the spinal subarachnoid space of the rat via a chronically inserted catheter produce a potent analgesia that can be antagonized by naloxone. The narcotics, acting only at the spinal level, changed cord function to block not only spinal reflexes but also the operant response to painful stimuli.

Journal ArticleDOI
TL;DR: The quadratic assignment paradigm developed in operations research is discussed as a general approach to data analysis tasks characterized by the use of proximity matrices in this article, and an extensive set of numerical examples are given illustrating the application of the search procedure to hierarchical clustering, the identification of homogeneous object subsets, linear and circular seriation, and a discrete version of multidimensional scaling.
Abstract: The quadratic assignment paradigm developed in operations research is discussed as a general approach to data analysis tasks characterized by the use of proximity matrices. Data analysis problems are first classified as being either static or non-static. The term ‘static’ implies the evaluation of a detailed substantive hypothesis that is posited without the aid of the actual data. Alternatively, the term ‘non-static’ suggests a search for a particular type of relational structure within the obtained proximity matrix and without the statement of a specific conjecture beforehand. Although the static class of problems is directly related to several inference procedures commonly used in classical statistics, the major emphasis in this paper is on applying a general computational heuristic to attack the non-static problem and in using the quadratic assignment orientation to discuss a variety of research tactics of importance in the behavioral sciences and, particularly, in psychology. An extensive set of numerical examples is given illustrating the application of the search procedure to hierarchical clustering, the identification of homogeneous object subsets, linear and circular seriation, and a discrete version of multidimensional scaling.

TL;DR: A simple method of estimating the average daily radiation for each calendar month on surfaces facing directly towards the equator has been presented by Liu and Jordan as discussed by the authors, verified with experimental measurements and extended to allow calculation of monthly average radiation on surfaces of a wide range of orientations.
Abstract: Several simplified design procedures for solar energy systems require monthly average meteorological data. Monthly average daily totals of the solar radiation incident on a horizontal surface are available. However, radiation data on tilted surfaces, required by the design procedures, are generally not available. A simple method of estimating the average daily radiation for each calendar month on surfaces facing directly towards the equator has been presented by Liu and Jordan [1]. This method is verified with experimental measurements and extended to allow calculation of monthly average radiation on surfaces of a wide range of orientations.

TL;DR: Peripheral receptive fields of “barrels” in the somatosensory neocortex (SmI) of rats were determined with microelectrode recording and anatomical techniques to indicate that each barrel receives information from one sinus hair.
Abstract: Peripheral receptive fields of "barrels" in the somatosensory neocortex (SmI) of rats were determined with microelectrope recording and anatomical techniques. A method of flattening each hemisphere prior to embedding was devised so that the organization of layer IV could be seen through the full extent of SmI on a single section. All of the barrels in the rat are located within layer IV of Smi. sinus hairs on the lateral and rostral face and furry buccal pad project to a continuous sheet of barrels in the head area of the contralateral SmI. The pattern of projections in this area indicates that each barrel receives information from one sinus hair. Large whisking vibrissae project to the largest cell-dense barrels and smaller non-whisking sinus hairs project to smaller barrels that are relatively cell-sparse. Barrels were also found outside of the head area in regions that receive projections from the forepaw and hindfoot. Receptive fields of these barrels are located on glabrous and hairy surfaces of the appendages that do not include any sinus hairs. Other parts of the body project to cell-dense areas of SmI that do not appear to contain barrels. Barrel subgroups and other somatotopic areas are separated by narrow barrel-free zones. As a result of this pattern of contrasting cell densities, an outline of the rat's body is delineated within layer IV.

TL;DR: This chapter examines the new compounds that have been added to the juvenile hormones family and discusses the molecular biology surrounding the long-sought JH receptor and potential candidates.
Abstract: Publisher Summary This chapter discusses the juvenile hormones (JH). The JH, a family of acyclic sesquiterpenoids, are essential to insect development and reproduction. This chapter examines the new compounds that have been added to the family. Recent structural elucidation of the hemolymph transport and catabolic proteins is examined. Molecular biology surrounding the long-sought JH receptor and potential candidates are discussed. The juvenile hormones, a family of acyclic sesquiterpenoids, are essential to insect development and reproduction. This family of hormones has been extensively studied because of its central role in regulating development and value as an insect pest control agent. Recent advances have been made in the areas of chemistry, biosynthesis, transport, catabolism, and biological roles the hormones play in the immature insect. Two common features characterize the naturally occurring JHs: their site of synthesis, the corpora allata (CA), and their farnesoid structure.

TL;DR: It is concluded that the cortical auditory region of man may be subdivided in two major areas: an area on the supratemporal plane representing the primary auditory area or A1 and a region surrounding A1 which perhaps comprises two areas, one on the superior temporal gyrus and the upper bank of the sylvian fissure including frontal and parietal operculi.
Abstract: Average responses to clicks were recorded from the exposed human cortex of 19 adult patients during operation for the treatment of intracranial diseases. Auditory evoked responses were obtained from two areas. Short latency potentials were recorded on the superior surface of the temporal lobe corresponding to the transverse temporal gyri. These responses consisted of two positive waves P1 and P2 separated by a negative wave N1. P1 had a mean latency of 14-7+/-1-5 ms, N1 a mean latency of 19-1+/-2-6 ms and P2 a mean latency of 32-2+/-4-1 ms. Responses to stimulation of the contralateral ear were of higher amplitude than responses to stimulation of the ipsilateral ear. Responses of smaller amplitude and longer latency were obtained from the superior temporal gyrus and the upper lip of the sylvian fissure. These responses had a mean peak latency for P1 of 40-2+/-2-6 ms, for N1 of 62-5+/-12-5 ms and for P2 of 97-7+/-17-2 ms. It is concluded that the cortical auditory region of man may be subdivided in two major areas: an area on the supratemporal plane representing the primary auditory area or A1 and a region surrounding A1 which perhaps comprises two areas, one on the superior temporal gyrus and one on the upper bank of the sylvian fissure including frontal and parietal operculi.
