This paper investigates how webmasters in first prize winning companies of web awards explain website quality. In order to gain insights into website quality descriptions, we held qualitative interviews with webmasters in eight Norwegian companies. The outcome is grounded theory models of how webmasters representing four ideal types of websites explain website quality. By using the left side of...

E-learning tools have profoundly transformed modern pedagogical approaches. Vendors provide different types of systems, such as self-paced (SP) and instructor–student interactive (ISI) elearning tools. Although both types of tools represent promising solutions to facilitate the learning process, it is important to theoretically identify a framework to evaluate the success of these tools and ass...

Menopause signals the end of reproductive period in women. However, fertility and fecundity decrease with increasing age prior to menopause demonstrating that changes premenopausal female tract (FRT) are already occurring negatively impact success. The effects on endometrium poorly understood, contrast ovary where occur affect successful reproduction. endometrial immune system is essential for ...

The evolutionary explanation of senescence proposes that selection against alleles with deleterious effects manifested only late in life is weak because most individuals die earlier for extrinsic reasons. This argument also applies to alleles whose deleterious effects are nongenetically transmitted from mother to progeny, that is, that affect the performance of progeny produced at late ages rat...

Adult aphid predators disperse across the landscape seasonally in search of prey aggregations that are patchily distributed and temporally variable. However, flight is energetically costly consumes resources could be invested reproduction. Hippodamia convergens an important predator North American cereal crops other agricultural systems. Consumption floral can enhance adult survival during peri...

W~SENDEN, B. D. 1993. Female convict cichlids adjust gonadal investment in current reproduction in response to relative risk of brood predation. Can. J. Zool. 71: 252 -256. Parental care theory predicts that investment in current reproduction should be increased when the prospects of success in current reproductive effort are relatively high, and reduced when they are poor relative to expected ...

Resting egg banks of microcrustaceans have been used to reconstruct the evolutionary and ecological history of species. However, recent studies provided evidence for a discrepancy between dormant propagules in the sediment and the planktonic population. This pattern raises two questions: First, what is the value of data on resting egg banks for population dynamics over time and second, which co...

BACKGROUND Demonstrating the impact that parents have on the fitness of their children is a crucial step towards understanding how parental investment has affected human evolution. Parents not only transfer genes to their children, they also influence their environments. By analyzing reproductive patterns within and between different categories of close relatives, this study provides insight in...
