On a statistic arising in testing correlation

This paper is devoted to the study of a certain statistic,u, defined on samples from a bivariate population with variances ₁₁, ₂₂ and correlation . Let the parameter corresponding tou be . Under binormality assumptions the following is demonstrated. (i) If ₁₁ = ₂₂, then the distribution ofu can be obtained rapidly from theF distribution. Statistical inferences about = may be based onF. (ii) In the general case, allowing for _{11 22}, a certain quantity involvingu,r (sample correlation between the variables) and follows at distribution. Statistical inferences about may be based ont. (iii) In the general case a quantityt may be constructed which involves only the statisticu and only the parameter . If treated like at distributed magnitude,t admits conservative statistical inferences. (iv) TheF distributed quantity mentioned in (i) is equivalent to a certaint distributed quantity as follows from an appropriate transformation of the variable. (v) Three test statistics are given which can be utilized in making statistical inferences about = in the case ₁₁ = ₂₂. A comparison of expected lengths of confidence intervals for obtained from the three test statistics is made. (vi) The use of the formulas derived is illustrated by means of an application to coefficient alpha.This research was supported by the National Institute of Child Health and Human Development, under Research Grant 1 PO1 HD01762.     

From ‘Is’ to ‘Ought’ in Moral Epistemology

Many philosophers claim that no formally valid argument can have purely non-normative premises and a normative or moral conclusion that occurs essentially. Mark Nelson recently proposed a new counterexample to this Humean doctrine:All of Dahlia's beliefs are true.Dahlia believes that Bertie morally ought to marry Madeleine. Bertie morally ought to marry Madeleine.I argue that Nelson's universal premise has no normative content, that Nelson's argument is valid formally, and that Nelson's moral conclusion occurs essentially and not vacuously. Nonetheless, I show that Nelson's argument faces a more fundamental problem if it is used in moral epistemology. An argument that appeals to a moral authority, such as Dahlia, might justify some moral belief out of a contrast class that does not include extreme views like moral nihilism; but it begs the question against moral nihilism, since one cannot be adequately justified in believing the conjunction of its premises without depending on assumptions that moral nihilists would deny. Thus, arguments like Nelson's can accomplish something important in moral epistemology, but their use is strictly limited.     

Pastoral counseling for self-transcendence: The integration of psychology and theology

Conclusion In the concept of self-transcendence pastoral counseling can integrate psychology and theology by seeing them as two complementary interpretations of the single radical drive of the human spirit. By moving beyond ourselves in creative understanding, realistic judgment, responsible decision, and generous love we both realize our authentic being (true self) and respond to the gospel's call to loving service of the neighbor. A psychology that understands self-realization as self-transcendence and a theology that recognizes the gospel as a call to self-transcendence require no connecting bridge or reconciliation, only the discovery of their intrinsic unity as interpretations of the same fundamental human drive for self-transcendence.
