How kinship structures alter inclusive fitness benefits or competition costs to members of a group can explain variation in animal societies. We present rare data combining behavioural associations and genetic relatedness to determine the influence of sex differences and kinship in structuring a two-tiered zebra society. We found a significantly positive relationship between the strength of beh...

This study develops and validates the IT knowledge relatedness construct to measure the extent to which a multi-business firm leverages related IT knowledge across its business units. It hypothesizes that synergies arising from IT knowledge relatedness differentiate performance of multi-business firms. This hypothesis is tested with primary data from senior IT executives of 315 Fortune 1000 fir...

Background The olfactory bulb is anatomically exposed and thus can be directly damaged by external stimulation. This can occur as an occupational injury owing to contact with organic solvents or other causes. We present cases of eight patients who sustained occupation-related exposure to potentially toxic substances and later presented with signs and symptoms of anosmia. We examined the occupat...

Title of Document: THE EFFECT OF RELATEDNESS ON MATING BEHAVIOR IN THE SATIN BOWERBIRD (Ptilonorhynchus violaceus) Sheila Mayo Reynolds, Doctor of Philosophy, 2010 Directed By: Dr. Gerald Borgia, Professor Behavior, Ecology, Evolution & Systematics Dr. Michael J. Braun, Adjunct Professor Behavior, Ecology, Evolution & Systematics Behavior is a main component of sexual selection theory in which ...

Theory predicts that when individuals live in groups or colonies, male-male aggression peaks at intermediate levels of local average relatedness. Assuming that aggression is costly and directed toward nonrelatives and that competition for reproduction acts within the colony, benefits of aggressive behavior are maximized in colonies with a mix of related and unrelated competitors because aggress...

The primary aim of the current study was to explore extent which videogame helping behaviour could be explained by need satisfaction and passion. extends previous research looking specifically at in-game has relevance for a range wellbeing outcomes as well reducing toxicity. Survey data were collected from 389 participants assessing satisfaction, passion, empathy during past four weeks. Path an...

We present an integer linear programming model of word sense disambiguation. Given a sentence, an inventory of possible senses per word, and a sense relatedness measure, the model assigns to the sentences’s word occurrences the senses that maximize the total pairwise sense relatedness. Experimental results show that our model, with two unsupervised sense relatedness measures, compares well agai...

Comparison measures to assess similarity, inclusion, and overlap of fuzzy sets are well known and widely used. This paper goes one step further by bootstrapping a more general concept of relatedness of fuzzy sets based on the relatedness of their elements. We study properties of 6 relatedness measures of this kind, and we illustrate their use in interesting applications such as information retr...

The spatial distribution of potential interactants is critical to social evolution in all cooperative organisms. Yet the biogeography of microbial kin discrimination at the scales most relevant to social interactions is poorly understood. Here we resolve the microbiogeography of social identity and genetic relatedness in local populations of the model cooperative bacterium Myxococcus xanthus at...
