Put modesty aside for a moment and let us know of an academic high. For example, if Craig was there he might tell us about his edited book Applied Evolutionary Psychology (<a href="http://ukcatalogue.oup.com/product/9780199586073.do">http://ukcatalogue.oup.com/product/9780199586073.do</a>) or Jack Griffey and Louise Lock and others might tell us they were doctored!

Once collected, de kort et al (2006) aggregated the data into two time points (week 1 and week 2), and were interested in the following main research questions about the feeding behaviour of the birds. 1) Is there any evidence of reciprocity in food sharing? 2) What is the general relationship between senders and receivers in terms of food sharing, and this relationship change over time? 3) Is food sharing more similar for jackdaws with similar characteristics (homophily effects)? They applied a largely descriptive analysis to the aggregated data. A statistical modelling approach can also be used with these aggregate data, regarding the 12 Jackdaws as a small network at each of the two time points, and using, separately for each of the two time points, the Generalised Bilinear Mixed Effects (GMBE) model (Hoff, 2005): based on the statistical framework of the Social Relations Model, but not restricted to the assumption of a normally distributed response. More recently, it transpires that de Kort et al have disaggregated behavioural data available for every food item in sequence over time, indicating whether a bird eats a food item itself, shares it with another bird, whether the item is stolen by another bird, or begged for by another bird. Given the substantive research questions about bird behaviour, such as reciprocity in food sharing, and these disaggregated data, we investigate the potential of the relational events model for understanding Jackdaw feeding behaviour, and discuss some interesting features of the Jackdaw data in the context of relational event modelling.<o:p></o:p></span></p><p class=MsoNormal style='text-align:justify'><span style='font-family:"Times New Roman","serif";color:black'><o:p> </o:p></span></p><p class=MsoNormal style='text-align:justify'><span lang=EN-US style='font-family:"Arial","sans-serif";color:black'>de Kort, S., Emery, N., Clayton, N., Aug. 2006.
