Political scientists are making increasing use of the methodologies of behavior genetics in an attempt to uncover whether or not political behavior is heritable, as well as the specific genotypes that might act as predisposing factors for—or predictors of—political "phenotypes." Noteworthy among the latter are a series of candidate gene association studies in which researchers claim to have discovered one or two common genetic variants that predict such behaviors as voting and political orientation. We critically examine the candidate gene association study methodology by considering, as a representative example, the recent study by Fowler and Dawes according to which "two genes predict voter turnout." In addition to demonstrating, on the basis of the data set employed by Fowler and Dawes, that two genes do not predict voter turnout, we consider a number of difficulties, both methodological and genetic, that beset the use of gene association studies, both candidate and genome-wide, in the social and behavioral sciences.

"Business Ethics for Better Behavior concisely answers the three most pressing ethical questions business professionals face: 1. What makes business practices right or wrong? 2. Why do normal, decent businesspeople of good will sometimes do the wrong thing? 3. How can we use the answer to these questions to get ourselves, our coworkers, our bosses, and our employees to behave better? Bad behavior in business rarely results from bad will. Most people mean well much of the time. But most of us are vulnerable. We all fall into moral traps, usually without even noticing. Business Ethics for Better Behavior teaches business professionals, students, and other readers how to become aware of those traps, how to avoid them, and how to dig their way out if they fall in. It integrates the best work in psychology, economics, management theory, and normative philosophy into a simple action plan for ensuring the best ethical performance at all levels of business practice. This is a book anyone in business, from an entry-level employee to CEO, can use"--

There is some evidence that sugar beet root tissue strength affects damage susceptibility and storage losses. This study aimed at analyzing the effect of N application and of irrigation on tissue strength of sugar beet varieties, on root composition, and on root tip breakage and storage losses. For this purpose, field trials in six replicates with three sugar beet varieties were carried out with three N doses in The Netherlands and Belgium in 2018 and 2019, alternatively with three irrigation treatments in Sweden in 2018 and 2019. Results show a low impact of N application and irrigation on puncture resistance, tissue firmness and compressive strength of the roots, while varieties differed always stronger and significantly. Cell wall composition (pectin, hemicellulose, cellulose, lignin) did not differ markedly in roots from different environments (sites, years) and varieties, giving no explanation for differences in tissue strength. However, the percentage of cell wall material (AIR, marc) and of dry matter were higher in roots with higher tissue strength. Root tip breakage and sugar losses during storage tended to be lower when root compressive strength of varieties was higher. Hence, root tissue strength could serve as an indirect selection criterion for reduced damage susceptibility and improved storability of sugar beet varieties.
