A THEORY OF CONCEPTUAL ADVANCE : EXPLAINING CONCEPTUAL CHANGE IN EVOLUTIONARY, MOLECULAR, AND EVOLUTIONARY DEVELOPMENTAL BIOLOGY by
The theory of concepts advanced in the dissertation aims at accounting for a) how a concept makes successful practice possible, and b) how a scientific concept can be subject to rational change in the course of history. Traditional accounts in the philosophy of science have usually studied concepts in terms only of their reference; their concern is to establish a stability of reference in order...
متن کاملIntervention thresholds: a conceptual frame for advance care planning choices
BACKGROUND Advance care planning (ACP) provides for decisions in the event of decisional incapacity. Determining ahead of time what a person may want is challenging and limits the utility of ACP. We present empirical evidence for a new approach to ACP: the individual's "intervention threshold." The intervention threshold is intuitively understood by clinicians and lay people, but has not been t...
متن کاملSufficiency on the Stock Market
It is well-known that there are a number of relations between theoretical finance theory and information theory. Some of these relations are exact and some are approximate. In this paper we will explore some of these relations and determine under which conditions the relations are exact. It turns out that portfolio theory always leads to Bregman divergences. The Bregman divergence is only propo...
متن کاملΦ - Divergences , Sufficiency , Bayes Sufficiency , and Deficiency
The paper studies the relations between φ-divergences and fundamental concepts of decision theory such as sufficiency, Bayes sufficiency, and LeCam’s deficiency. A new and considerably simplified approach is given to the spectral representation of φ-divergences already established in Österreicher and Feldman [28] under restrictive conditions and in Liese and Vajda [22], [23] in the general form...
متن کاملSufficiency in Blackwell's theorem
If one information service is more informative than the other, then any agent values it more. In fact, the opposite implication (sufficiency) is also true, and this characterization is the celebrated Blackwell’s theorem. We present here a short proof of sufficiency. Actually, we show a stronger result: it is enough to check whether the value of the service is greater than the value of the other...
