Regression test selection: theory and practice
… of both tests and revisions. Regression test selection (RTS) speeds up regression testing by selecting to run only tests that are affected by project changes. RTS is efficient if the time to select tests is smaller than the time to run unselected tests; RTS is safe if it guarantees that …

Selection theory for infinite dimensional spaces and continuous single-valued approximations to upper semi-continuous multivalued mappings
<p>The extension problem is one of the fundamental problems of topology; if TX and Y are topological spaces and A is a closed subset of X and f:A —> Y is a continuous function, under what conditions is there »a continuous function fzx + Y such‘ that fIA = f ? Two key theorems of topology deal with …

Marital status and well-being
… The second hypothesis, one known as the selection theory, was also tested. According to the selection theory, marital status is a consequence of selectivity, in that preexisting variables such as well-being predispose people to certain marital statuses. Accordingly, people who report high …

Immunologic Memory to Polysaccharide Antigens
… previously encountered antigens. The clonal selection theory of acquired immunity attributes immunologic memory to the formation of an expanded compartment of quiescent antigen-specific memory B cells that are capable of rapid activation upon secondary antigen encounter. Whereas protein …

A quantitative model of density-dependent habitat selection: integrating isodar and isoleg theories
… advanced to explain density-dependent habitat selection, but few models address multiple species interactions and even fewer simulate these phenomena. Moreover, the development of quantitative models that incorporate multiple species interactions is in its infancy with existing models being …

Sociosexual Development: Infusing the Belsky, Steinberg, and Draper Model with Sexual Selection
Life history theory attempts to explain between- and within-species variation in maturational and reproductive patterns, whereas sexual selection attempts to explain between- and within-sex differences in intersexual mate choice and intrasexual competition for members of the opposite sex. These two …

Embryology and the evolutionary synthesis: Waddington, development and genetics
… within mid twentieth century evolution theory, is discussed in the context of the growth to dominance of natural selection as the orthodox mechanism of adaptive evolution. The unification of neo-Mendelian heredity and neo-Darwinian selection theory, is descnbed as the core of modern …

Creativity : psychological and evolutionary perspectives
… emergence of creative ability is sexual selection. This suggests that the ability to produce creative products arose to advertise the qualities of the artist and thereby attract sexual partners. Thus the higher the quality of the product the greater the number of mates the artist will …

The validation of the selection of male British army officers
… the Regular Commissions Board and the War office Selection Boards,, outlines the current officer selection and training procedures, and then describes the research methodology. The research analyzes the validity,, utility and fairness of the Regular Commissions Board as a method for the selection …

Physical attractiveness, altruism and fairness in a game-theoretic framework
… evolution of altruism through the lens of sexual selection theory, hypothesising that altruism leads to increased chances of being chosen as a mate, particularly as females value altruistic tendencies in a romantic partner. As a result, it was hypothesised males would be more cooperative and …

Proximate and ultimate factors influencing honey bee reproductive-related behavior
… workers invest in their own reproduction as kin selection theory would suggest, they do not cease altruistic behaviors. Reproductive workers are as likely as non-reproductive workers to perform dangerous tasks and provide metabolically costly services that may reduce their own reproduction. The …

Salamander Mating Behaviors and Their Consequences for Individuals and Populations
… I studied female mating behavior, sexual selection, and the consequences of polyandry for individual females and salamander populations. I also compared the performance of several statistical approaches for analyzing genetic mating system data. The first chapter summarizes the …

Social and environmental causes and reproductive consequences of ornamented plumage in the Red-backed Fairywren (Malurus melanocephalus)
Sexual selection theory proposes that ornaments used in mate choice should convey honest information about the quality of a signaler to conspecifics. In my dissertation, I address two major hypotheses for how signal honesty is maintained, the social cost hypothesis and the physiological cost …

Parental investment and physical aggression among males
… this sex difference involve variants of learning theory and a tabula rasa psychology. Sexual selection theory provides a more coherent ultimate explanation for sex differences in this and other domains of behaviour. The key processes in sexual selection (preferential mate choice and intra-sexual …

New statistical techniques for designing future generation retirement and insurance solutions

Extra-pair paternity within the female-defense polygyny of the lizard, Anolis carolinensis: Evidence of alternative mating strategies
… competition is a prominent component of sexual selection theory. Typically, males attempt to mate with the most females possible and females attempt to mate with the highest quality males possible. In the polygynous female-defense mating system of Anolis carolinensis, males compete directly for …

Nest site selection by common eiders : relationships with habitat features, microclimate and incubation success
Habitat selection theory presumes that organisms are not distributed randomly in their environments because of habitat-specific differences in reproductive success and survival; unfortunately, many previous studies were either unable or failed to look for evidence of processes shaping nest site …

Polymorphic social organisation in a eusocial insect : the ultimate and proximate causes
… to what is assumed by the majority of skew theory - that control lies with individuals in direct competition over reproduction (queens) - I show that a third party (the workers) plays a principle role in determining which queen reproduces in the colony. Genetic analyses also revealed that …
