Adopting a much broader notion of thinking than that associated with the Critical Thinking movement, this paper addresses the question of thinking skill generality. An analysis of the concept of ‘thinking skill’ suggests ways in which this notion has been misapplied. The paper demonstrates the importance of thinking tasks and argues for a non–universalistic notion of thinking skill generality. The domains–view of thinking is assessed, evidence from secondary research being used to show that thinking skills are not domain–specific simply by (...) virtue of being instantiated with disciplinary content. The prevalence of general procedural knowledge in our thinking practices notwithstanding, empirical evidence suggests the existence of at least two kinds of domain–specific thinking skills: those in which thinking is essentially the application of domain–specific declarative knowledge; and those addressing specialised, domain–specific, thinking tasks.

Chi sites are examples of special sites enhancing homologous recombination in their region of the chromosome. Chi, 5′ G‐C‐T‐G‐G‐T‐G‐G3′, is a recognition site for the RecBC enzyme, which nicks DNA near Chi as it unwinds DNA. A molecular model of genetic recombination incorporating these features is reviewed.

""This volume contains the substance of the lectures which were delivered on the Nathaniel William Taylor foundation at the Spring conference of alumni of Yale Divinity School and ministers of Connecticut at New Haven in April, 1912. After they had been delivered, it seemed best to profit by the comments of those who heard them, and to gain the advantage of criticisms on the part of two or three friends who were good enough to read the manuscript. As a result, (...) some minor changes have been made so as to avoid misinterpretation in one or two points; but the substance of the discussion remains practically unchanged. The final lecture of the course, which was too long to be read in its entirety, has been divided and slightly expanded in order to give space for a more detailed exposition."" -- From the Preface.
