In this paper, we investigate the rules that should underlie a computer program that is capable of revising its beliefs or opinions. Such a program maintains a model of its environment, which is updated to reflect perceived changes in the environment. This model is stored in a knowledge base, and the program draws logical inferences from the information in the knowledge base. All the inferences drawn are added to the knowledge base. Among the propositions in the knowledge base, there are (...) some in which the program believes, and there may be others in which the program does not believe. Inputs from the outside world or reasoning carried out by the program may lead to the detection of contradictions, in which case the program has to revise its beliefs in order to get rid of the contradiction and to accommodate the new information.

We draw on the behavioral agency model to explore the ethical consequences of CEO equity incentives. We argue that CEOs are more concerned with funding pension plans when they have more to gain from their stock options yet will increasingly underfund employee pension funds as their current option wealth increases. Our findings reveal that both effects hold when the CEO has greater power (also occupying board chair) over firm decision making. Our study suggests that there is an ethical dimension to (...) equity incentives, given they are intended to align CEO interests with shareholders, yet potentially incentivize CEO behaviors with adverse consequences for employees. Insights from our findings provide boards and regulators with behavioral levers to protect employee well-being in the context of pension funding. (shrink)

The focus of this paper is one of James Prescott Joule’s scientific contributions: the laws of heat production by electric currents in conductors. In 1841, the 22 years old Joule published a paper with the title “On the heat evolved by metallic conductors of electricity, and in the cells of a battery during electrolysis” where he presented an experimental study of that phenomenon and proposed two laws that were allegedly supported by his trials. On closer inspection, both his laboratory work (...) and his inferences can be challenged. The emphasis of this article is an attempt to understand Joule’s experimental undertaking, its highpoints and shortcomings, by a detailed analysis of this specific episode and by studying the precedents of his work and subsequent advancements. It is possible to point out several serious deficiencies of that investigation, and Joule’s contemporaries, such as Edmond Becquerel and Heinrich Lenz, did criticize some of his flaws and undertook new experiments to provide a sound basis for those laws. Besides providing a historical examination of that specific episode, this article uses this case study to tackle some features of the nature of science that may contribute to scientific education.

We point out that current belief revision operations can be used to revise non-monotonic theories and we propose a new operation, called permissive belief revision. The underlying idea of permissive belief revision consists of instead of abandoning some beliefs during a revision, transforming those beliefs into weaker ones, while still keeping the resulting belief set consistent. This framework allows us to keep more beliefs than what is usual using existing belief base-based revision theories.

Live donor kidney transplantation is the best treatment option for most patients with late-stage chronic kidney disease; however, the rate of living kidney donation has declined in the United States. A consensus conference was held June 5-6, 2014 to identify best practices and knowledge gaps pertaining to live donor kidney transplantation and living kidney donation. Transplant professionals, patients, and other key stakeholders discussed processes for educating transplant candidates and potential living donors about living kidney donation; efficiencies in the living donor (...) evaluation process; disparities in living donation; and financial and systemic barriers to living donation. We summarize the consensus recommendations for best practices in these educational and clinical domains, future research priorities, and possible public policy initiatives to remove barriers to living kidney donation.

From the beginning of the seventeenth century it has generally been held that the second Medicean is the parent of all the other extant manuscripts. In two articles C. W. Mendell has demonstrated that Leidensis B.P.L. 16. B is the manuscript once owned by Rudolphus Agricola and later by Th. Ryck, whose edition makes frequent allusion to its readings. Mendell's attempt to show further that L represents a tradition independent of the Medicean has found little support until recently, when E. (...) Koestermann, in the course of preparing the latest Teubner edition of Annals and Histories became convinced from his own study of L that Mendell's view—in spite of some arguments of dubious validity—was essentially correct. In an article in Philologus and in the preface to his edition of Histories Koestermann has marshalled the arguments which he believes prove L's independence of the Medicean line of descent. Since the new valuation that Koestermann puts upon L has produced a drastic revision of both text and apparatus criticus in his new editions, it may be worth while to examine the evidence that Koestermann adduces in support of his belief in L's independence.

Professor Skutsch has convicted me of one error—the inclusion of Eun. 465 in my list on p. 208. I do not feel, however, that he has proved that Phaedria is a dactyl in Terence. The essence of his argument, as I see it, depends on the figures in the last two rows of the first two columns on p. 90, and may be stated as follows: ‘Forms undeniably dactylic, such as Pamphile, are always followed by a disyllabic thesis. The thesis (...) after all critical examples of Phaedria is disyllabic. Therefore “Phaedria is proved to be a dactyl”.’ My objection to this argument is not that it is not a logical syllogism, but that it seeks to establish the prosody of Phaedria without considering the prosody of the other Phaedria-typt1 names in Terence. These are listed on p. 208 of my article . The following cases, I suggest, merit consideration. (shrink)

The focus of this study was to analyze the content, distribution, and comparative genome relationships of 996 chromosome bin-mapped expressed sequence tags accounting for 2266 restriction fragments on the homoeologous group 3 chromosomes of hexaploid wheat. Of these loci, 634, 884, and 748 were mapped on chromosomes 3A, 3B, and 3D, respectively. The individual chromosome bin maps revealed bins with a high density of mapped ESTs in the distal region and bins of low density in the proximal region of the (...) chromosome arms, with the exception of 3DS and 3DL. These distributions were more localized on the higher-resolution group 3 consensus map with intermediate regions of high-mapped-EST density on both chromosome arms. Gene ontology classification of mapped ESTs was not significantly different for homoeologous group 3 chromosomes compared to the other groups. A combined analysis of the individual bin maps using 537 of the mapped ESTs revealed rearrangements between the group 3 chromosomes. Approximately 232 of the consensus mapped ESTs matched sequences on rice chromosome 1 and revealed large- and small-scale differences in gene order. Of the group 3 mapped EST unigenes ∼21 and 32% matched the Arabidopsis coding regions and proteins, respectively, but no chromosome-level gene order conservation was detected. (shrink)
