So far in this course we have dealt entirely with the evolution of characters that are controlled by simple Mendelian inheritance at a single locus. There are notes on the course website about gametic disequilibrium and how allele frequencies change at two loci simultaneously, but we didn’t discuss them. In every example we’ve considered we’ve imagined that we could understand something about evolution by examining the evolution of a single gene. That’s the domain of classical population genetics. For the next few weeks we’re going to be exploring a field that’s actually older than classical population genetics, although the approach we’ll be taking to it involves the use of population genetic machinery. If you know a little about the history of evolutionary biology, you may know that after the rediscovery of Mendel’s work in 1900 there was a heated debate between the “biometricians” (e.g., Galton and Pearson) and the “Mendelians” (e.g., de Vries, Correns, Bateson, and Morgan). Biometricians asserted that the really important variation in evolution didn’t follow Mendelian rules. Height, weight, skin color, and similar traits seemed to

The measurement of meaning

\"What are your assumptions (implicit as well as explicit) about the most effective way to manage people?\" So began Douglas McGregor in this 1960 management classic. It was a seemingly simple question he asked, yet it led to a fundamental revolution in management. Today, with the rise of the global economy, the information revolution, and the growth of knowledge-driven work, McGregor's simple but provocative question continues to resonate-perhaps more powerfully than ever before. Heralded as one of the most important pieces of management literature ever written, a touchstone for scholars and a handbook for practitioners, The Human Side of Enterprise continues to receive the highest accolades nearly half a century after its initial publication. Influencing such major management gurus such as Peter Drucker and Warren Bennis, McGregor's revolutionary Theory Y-which contends that individuals are self-motivated and self-directed-and Theory X-in which employees must be commanded and controlled-has been widely taught in business schools, industrial relations schools, psychology departments, and professional development seminars for over four decades. In this special annotated edition of the worldwide management classic, Joel Cutcher-Gershenfeld, Senior Research Scientist in MIT's Sloan School of Management and Engineering Systems Division, shows us how today's leaders have successfully incorporated McGregor's methods into modern management styles and practices. The added quotes and commentary bring the content right into today's debates and business models. Now more than ever, the timeless wisdom of Douglas McGregor can light the path towards a management style that nurtures leadership capability, creates effective teams, ensures internal alignment, achieves high performance, and cultivates an authentic, value-driven workplace--lessons we all need to learn as we make our way in this brave new world of the 21st century.

Social Psychology of Organizations

As a result of the controversy over the dimensionality of the ethos/source credibility construct and the associated plethora of empirical studies in the 1960s and 1970s, Aristotle's dimension of “goodwill” has been dismissed by many contemporary theorists and researchers. It is argued that this occurred as a result of errors made in the earlier empirical research and that “goodwill” can be measured, contrary to earlier claims, and should be restored to its former status in rhetorical communication theory. Empirical research is reported indicating the existence of the goodwill dimension as part of the structure of the ethos/source credibility construct and a measure of that dimension is provided with evidence for its reliability and validity.

Goodwill: A reexamination of the construct and its measurement

Editors Note: With this issue we inaugurate a new section of HCR devoted to summaries of research and theory in specialised areas within the field of human communication. Papers in this section will he designed to bring research and theory in a given area together so that both specialists and nonspecialists can determine the “state of the art” in that area up to the time the paper is published. Scholars who wish to prepare papers for this section are requested to contact the editor and make their interests known. Generally, papers for this section will be commissioned. However, unsolicited papers will be given full consideration.

Oral communication apprehension: a summary of recent theory and research

The study reports a factor analytic investigation of the interpersonal attraction construct. Two‐hundred and fifteen subjects completed 30 Likert‐type, seven‐step scales concerning an acquaintance. Factor analysis indicated three dimensions of the interpersonal attraction construct which were labeled “task” “social” and “physical.” The results of this study and four replications suggest that the resulting 15‐item instrument can be expected to measure reliably three dimensions of interpersonal attraction.
