plexity. This conclusion is conceptually similar to our own, and it little alters the broader impacts of our published findings; still, the general relevance of the issues warrants a response. In their reanalysis, Gutierrez-Ibanez et al. [2016] perform a ‘residual analysis’, which regresses body weight on brain weight with phylogenetic generalized least squares (PGLS) to obtain size-corrected r...

OBJECTIVES To describe the morphological features of atherosclerosis in the aortas of autopsied patients (ranging from young adults to the elderly), thus providing new tools for a more sensitive morphological evaluation. METHOD We collected 141 aorta samples. We assessed the macroscopic degree of atherosclerosis, thickness of the intima and media, lipid and collagen depositions in the intima,...

General interpolating expressions, valid for nearand arbitrary overcritical sizes of clusters, are proposed for the nucleation fluxes and distributions. Results are expressed in terms of the deterministic growth rates, and are characterized by a non-Gaussian dependence on the size of nuclei. In a sense, the proposed approximations combine the positive aspects of the parabolic model by Trinkaus ...

One of the most critical problems that hospitality firms face in selecting employees is that the use of cognitive ability tests and other valid predictors of job performance lead to subgroup differences between majority and minority group members. The recent Ricci v. DeStefano U.S. Supreme Court case provides new implications for the adverse diversity-validity dilemma. This paper seeks to bridg...

The differential sensitivities of A beta, A delta and C fibres of rat vagus nerve to bupivacaine, etidocaine and AL-381 were studied in vitro. In A beta fibres, at 35-37 degrees C, 50 mumole litre-1 of the drugs had similar effects on the action potential amplitude, while at greater concentrations (100 and 200 mumole litre-1) the greatest mean depression of amplitude was seen with etidocaine (n...

The Formosan subterranean termite, Coptotermes formosanus Shiraki is currently one of the most destructive pests in the USA. It is estimated to cost consumers over US dollars 1 billion annually for preventative and remedial treatment and to repair damage caused by this insect. The mission of the Formosan Subterranean Termite Research Unit of the Agricultural Research Service is to demonstrate t...

It has long been recognized that the media play an essential role in democracy. However, even in the absence of censorship, the government may in‡uence news content by maintaining a “cozy”relationship with the media. This paper develops a simple model of democratic politics in which the actual freedom of the press is endogenous. In equilibrium, the features of the media market determine the abi...
