Employee portals are utilized by many companies to improve information exchange and communication between their employees as well as to better support business processes. Assessing the benefits of employee portals has become important, owing to limited IT budgets and the need to justify investments in portals. In this paper, we propose a conceptual model for measuring the effectiveness of emplo...

The present research-in-progress makes significant contribution to the research in the e-enabled supply chain management (eSCM) area by extending the DeLone and McLean information systems success model and e-commerce success model to an eSCM success model. It also extends the earlier Mahmood et al. (2005) eSCM success model by incorporating the service quality construct introduced in the DeLone...

Evaluation of the success of professional virtual communities (VCs) has been the focus of many organizations. However, there are still few empirical studies conducted to examine online knowledge sharing behavior that has been thought as the most important element for VC success. In this study, by integrating two schools of thoughts (trust theory and self-efficacy expectation) with IS Success Mo...

Parental investment in reproduction is adjusted according to potential benefits in terms of offspring survival and/or mating success. If male quality affects the reproductive success of a female, then females mating with high-quality males should invest more in reproduction. Although the subject has been of general interest, further experimental verification of the hypothesis is needed. We stud...

Climate change and associated changes in weather patterns have globally widespread effects on natural systems. Shifts phenology can affect the reproductive success of birds by causing a mismatch between onset breeding favourable conditions for reproduction, such as peak food availability. Weather their also long been discussed affecting grouse (Tetraoninae) contributing to rapid declines many c...

Since that historically the first human birth was registered through in vitro fertilization in 1978, the improvement and creation of new assisted reproduction techniques such as intracytoplasmic sperm injection and physiological intracytoplasmic sperm injection have become of great importance nowadays. Louise Brown was the first baby conceived through in vitro fertilization in England. Since th...

Paternity insurance and dominance tenure length are two important components of male reproductive success, particularly in species where reproduction is highly skewed towards a few individuals. Identifying the factors affecting these two components is crucial to better understand the pattern of variation in reproductive success among males. In social species, the social context (i.e. group size...

Female aspic vipers (Vipera aspis) are ‘‘capital breeders,’’ and delay reproduction until they have amassed large energy reserves. Data from an eight-year mark– recapture study on free-ranging vipers suggest that potential costs of reproduction were high for these animals, in terms of survival as well as growth and energy storage. Females that reproduced experienced higher mortality rates than ...

Accurate inferences on population genetics data require a sound underlying theoretical null model. Organisms alternating sexual and asexual reproduction during their life-cycle have been largely neglected in theoretical population genetic models, thus limiting the biological interpretation of population genetics parameters measured in natural populations. In this article, we derive the expectat...
