Darcy's law is a phenomenological relationship for fluid flow rate that finds one of its principle applications in hydrology. Theoretical hydrologists rely upon a multiplicity of conceptual models to carry out approximate derivations of Darcy's law. These derivations provide structural explanations of the law; they require the application of fundamental principles, such as conservation of momentum, to idealized models of the porous media within which the flow occurs. In practice, recognition of the idealized conditions incorporated into models facilitates the empirical (...) clarification of the domain within which the law remains accurate. Structural explanations also contribute to the physical interpretation of phenomenological parameters. (shrink)

Le sens désigne la subjectivité du sujet. II n’est pas seulement une disposition effective de l'âme, de lui il у a aussi un savoir. Le savoir du sens appartient à la connaissance, et il s’oriente vers une verité ou exactitude qui lui sont particulières. La connaissance de la chose et la connaissance du sens se distinguent par le sens différent qui anime et forme l'une et l'autre. La connaissance de la chose s’accomplit par la transcendance, par l’addition de l'autre à (...) la conscience qui se connaît elle-même. La connaissance du sens s’accomplit comme « Introscendance concentrique » ; eile veut approfondir le sens à chercher, en l’exposant dans l’image des expériences diverses, que le sens rend possible. La connaissance de la chose et celle du sens tombent sous deux logiques de pôle opposé ; ces deux logiques répondent à la différence corrélative de l’altérité des choses et de l’identité du sens.

Heathcare spending, which was almost 13% of the gross national product last year, is estimated to jump to 14% in 1992. For the first time, hosital expenditures are projected to exceed $300 biilion, representing over 38% of the nation's total healthcare bill. In an effort to reduce federal and state budget deficits and to stimulate institutional cost containment, Medicare and Medicaid officials are becoming even more parsimonious in negotitation reimbursement levels.

Excerpt from Empfindung und Vorstellung: Ein Beitrag zur Klarung Psychologischer Grundbegriffe Vor kurzem erschien eine Abhandlung von Carl Stumpf uber Empfindung und Vorstellung, welche auf Grund feinfuhliger Selbstbeobachtungen und unter Berucksichtigung der grossen einschlagigen Literatur in die vielen Winkel und Dunkelheiten dieses Problems der deskriptiven Psychologie hineinleuchtet. Unter sorgfaltiger Analyse der von den verschiedenen Beobachtern gegebenen Beschreibungen und scharfsinniger Untersuchung der logischen Durchfuhrbarkeit jeder einzelnen der bisher ausgesprochenen Auffassungen versucht diese Abhandlung die Frage zu klaren, worin der wesentliche Unterschied beider (...) Erlebnisarten besteht. Als Ergebnis gelangt Stumpf in der Hauptsache zu einer Rechtfertigung der altuberlieferten Auffassung, nach der ein "spezifischer" Unterschied zwischen Empfindung und Vorstellung nicht vorliegt, sich die Vorstellungen vielmehr vor allem durch ihre geringere Intensitat von den Empfindungen unter-scheiden. Ausser an Intensitat fehlt es den Vorstellungen im Gegensatz zu den Empfindungen an Fulle und Bestandigkeit, ferner sind sie dadurch charakterisiert, dass sie willkurlich leichter modifizierbar sind, dass ihnen gegenuber der Glaube an die Realitat fur das erlebende Bewusstsein einer Rechtfertigung bedarf, und dass sie durchschnittlich schwachere Gefuhlswirkungen mit sich fuhren. Vorstellungen stellen sich so den Empfindungen gegenuber als "Erscheinungen zweiter Ordnung" dar: in dem Inhalt der Erlebnisse, nicht in den Akten des Erlebens, ist ihre Verschiedenheit zu suchen.

Like some ethical dilemmas, this question has an obvious answer that may not be right. On first reflection, it seems entirely unreasonable and inappropriate to expect staff members to withhold supportive care. Legally, a designated surrogate has the authority to refuse pain medication on the patient's behalf, but is it ethically defensible? A patient lacking decisionmaking capacity is crying out in pain; can we really imagine just closing the door? What do we say to other patients, visitors, and staff members, (...) such as physicians, nurses, housekeepers, and dietary workers, who might hear the patient? Do we place a sign on the door, one noting that the surrogate has refused, on behalf of the patient, to authorize the administration of pain medication and that the hospital or nursing home must comply with the surrogate's decision?

The following description is based upon an actual case in which a patient initiated legal action after suffering a complication subsequent to an invasive diagnostic procedure performed by a senior fellow. Named as codefendants were the senior fellow, attending physician, and the hospital. Because any hospital with house staff is potentially vulnerable to similar litigation, Ethics Committees at Work is addressing the questions raised by this dilemma.

The belated but formal acknowledgment of medical errors and their impact has been well documented. Curiously, the topic of management or executive mistakes in healthcare is not raised in professional meetings nor, until recently, addressed by an article in health administration journals.

Our ethics committee is revising the organization's policy on forgoing life-sustaining treatment. The current policy now includes the statement, “When life-sustaining treatment is forgone, supportive care will be provided to relieve pain and ensure the patient's comfort, unless the patient or surrogate refuses those measures.” Is it reasonable, however, for the surrogate to have the authority to refuse consent for pain medication and/or other supportive care?
