Callous-unemotional and borderline traits, antisocial behaviors, depressive symptoms and social anxiety were assessed in 972 high-school students. Cluster analysis yielded four groups: a low traits group, a second group that was above the mean in callous-unemotional traits and below the mean in borderline traits (moderate callous-unemotional traits cluster), a third group that was well above th...

Certain clinical traits (e.g., ruminative response style, self-criticism, perfectionism, anxiety sensitivity, fear of negative evaluation, and thought suppression) increase the risk for and chronicity of emotional disorders. Similar to traditional personality traits, they are considered dispositional and typically show high temporal stability. Because the personality and clinical-traits literat...

Traits offer a fine-grained mechanism to compose classes from reusable components while avoiding problems of fragility brought by multiple inheritance and mixins. Traits as originally proposed are stateless, that is, they contain only methods, but no instance variables. State can only be accessed within traits by accessors, which become required methods of the trait. Although this approach work...

Relationships between breeding field-test traits and competition traits were studied to investigate whether the latter could be usefully included in the genetic evaluation of Icelandic horses. The current method of genetic evaluation is based on records from breeding field-tests only. The breeding field-test data included 16401 individual records of Icelandic horses evaluated in 11 countries du...

Despite the undisputed prominence of inheritance as the fundamental reuse mechanism in object-oriented programming languages, the variants – single inheritance, multiple inheritance, and mixin inheritance – all suffer from conceptual and practical problems. Traits overcome the problems arising with the different variants of inheritance. Traits are essentially groups of methods that serve as bui...

Traits are fine-grained components that can be used to compose classes, while avoiding many of the problems of multiple inheritance and mixin-based approaches. Since most implementations of traits have focused on dynamically-typed languages, the question naturally arises, how can one best introduce traits to statically-typed languages, like Java and C#? In this paper we argue that the flattenin...

In the last decades, beef cattle breeding mainly focused on improving production and reproduction traits. Nowadays, there is a growing interest to include behavior and type traits in the breeding goal. There is an interest in behavior as it is associated with human safety and workability and in type traits as they might be associated with longevity of cows. The objective of the current study wa...

Mendelian traits are considered as the lower end of the complexity spectrum of heritable phenotypes. However, more than a century after the rediscovery of Mendel's law, the global landscape of monogenic variants as well as their effects and inheritance patterns within natural populations is still not well understood. Using the yeast Saccharomyces cerevisiae, we performed a species-wide survey o...

The role of Beringia as a refugium and route for trans-continental exchange of fauna during glacial cycles of the past 2million years are well documented; less apparent is its contribution as a significant reservoir of genetic diversity. Using mitochondrial DNA sequences and 14 microsatellite loci, we investigate the phylogeographic history of caribou (Rangifer tarandus) in western North Americ...
