Inferential statistical tests-such as analysis of variance, t-tests, chi-square and Wilcoxin signed ranks-now constitute a principal class of methods for the testing of scientific hypotheses. In this paper I will consider the role of one statistical concept (statistical power) and two statistical principles or assumptions (homogeneity of variance and the independence of random error), in the reliable application of selected statistical methods. I defend a tacit but widely-deployed naturalistic principle of explanation (E): Philosophers should not treat as inexplicable or basic those correlational facts that scientists themselves do not treat as irreducible. In light of (E), I contend that the conformity of epistemically reliable statistical tests to these concepts and assumptions entails at least the following modest or austere realist commitment: (C) The populations under study have a stable theoretical or unobserved structure that metaphysically grounds the observed values; the objects therefore have a fixed value independent of our efforts to measure them. (C) provides the best explanation for the correlation between the joint use of statistical assumptions and statistical tests, on the one hand, and methodological success on the other.

Do predictions of novel facts provide stronger evidence for a theory than explanations of old ones? Sometimes yes, sometimes no. Which obtains has nothing to do with whether the evidence is predicted or explained, but only with the selection procedure used to generate the evidence. This is demonstrated by reference to a series of hypothetical drug cases and to Heinrich Hertz's 1883 cathode ray experiments.

Many ecologists have dismissed alleged ecological laws as tautological or trivial. This essay investigates the epistemological status of one prominent such "law," the population-growth thesis, and argues for 4 claims: (1) Once interpreted, the thesis cannot be denied the status of empirical law on the grounds that it is always and everywhere untestable. (2) Contrary to Peters' (1991) claim, some interpretations of the thesis have significant heuristic power. (3) One can use the reasoning of Brandon (1990), Lloyd (1987), and Sober (1984) to show that some interpretations of the thesis are not a priori. (4) Even if the thesis is a priori, it has explanatory power as a "schematic law."

A realist causal model of quantum cosmology (QC) is developed. By applying the de Broglie-Bohm interpretation of quantum mechanics to QC, we resolve the notorious 'problem of time' in QC, and derive exact equations of motion for cosmological dynamical variables. Due to this success, it is argued that if the situation in QC is used as a yardstick by which other interpretations are measured, the de Broglie-Bohm theory seems uniquely fit as an interpretation of quantum mechanics.

Newborn screening for the genetic disease phenylketonuria (PKU) is generally considered the greatest success story of applied human genetics. Even those generally skeptical of the value of genetic testing often comment enthusiastically on this program. In fact, PKU screening has been plagued with serious problems since its inception in the early 1960s. This essay describes some of these difficulties and asks what lessons they hold for other screening programs. It also argues that realism in our assessment of such programs requires that we pay greater attention to the concrete experience of families. How screening should work in theory is of less importance than how it does work in practice.

Faraday's view of the mutual relation of speculative theories and laws of nature implies that there should be a procedure, leading from speculative considerations to a system of facts and laws in which theories do no longer play any role. In order to make out the degree in which Faraday's claims correspond to his practice, the way in which he gains an explanation of Arago's effect is analyzed. The thesis is proposed that he indeed has a procedure of leaving theories aside. It is intimately connected with certain methodological guidelines of his experimentation.

Social scientists regularly make use of multivariate models to describe complex social phenomena. It is argued that this approach is useful for modelling the variety of cognitive and social factors contributing to scientific change, and superior to the integrated models of scientific change currently available. It is also argued that care needs to be taken in drawing normative conclusions: cognitive factors are not instrinsically more "rational" than social factors, nor is it likely that social factors, by some "invisible hand of reason," generally work to produce scientific success. A multivariate model of the biasing factors within a scientific community at particular times is developed. This model, which is an example of work in social epistemology, yields normative conclusions.

There seems the prospect, at this juncture, of articulating programs of research in science studies that will be genuinely interdisciplinary, integrating philosophical, historical, and sociological/anthropological interests in science. This introduction describes the rationale for the symposium, "Discourse, Practice, Context," to which four contributors were invited whose work across disciplinary boundaries puts them in a position to take stock of these initiatives and their impact on existing disciplinary practice.

Debates over the significance of the particle concept, and the problem of locality-how do we represent localized phenomena?-appear to presuppose that particles and observed phenomena are things rather than events. Well-known theorems (Hergerfelt, Reeh-Schlieder), and a recent variant of Hergerfelt's theorem due to David Malement, present a problem of locality only given the tacit appeal to the concept of thing, in fact an individual, in a sense contrary to particle indistinguishability. There is no difficulty with the particle concept per se, but it is a global construction more than one step removed from events actually observed, which are represented by local integrals over self-adjoint field densities.
