In this chapter, we present our studies of functional cranial morphology and evolution from Mesolithic through Christian times. The chapter includes an overview of the univariate and multivariate statistical techniques we used. By using these techniques, we were able to demonstrate patterns of facial reduction—most particularly reductions in the chewing apparatus—that is consistent with the dietary shift from the course, abrasive diet associated with Mesolithic populations to the higher-carbohydrate, more-processed diet associated with Neolithic food production. This transition from gathering to food-producing technologies, seen in the correlation between facial reduction and food production, is consistent in other populations beyond the Nile Valley.

The aim of this study is to analyze the perception of the meaning of sustainability in the food sector. A sample of 268 University students belonging to the Millennial generation was identified and a survey was carried out to assess the interaction between this kind of Millennials and food sustainability. Collected data were explored with descriptive statistics, followed by multivariate statistical techniques to get an integrated vision of relationships among the variables. Outcomes evidence four groups of Millennials with specific peculiarities, i.e., “Socio-Nature Sensitives”, characterized by a high level of attention for the socio-economic dimension and sustainable ways of food production; “Info-Supporter”, very sensitive to labeling and warranty systems; “Proactive-Oriented”, interested in innovative activities; “Indifferent Millennials”, assigning the issue in general a low level of importance. Results provide useful information and some contribution to public institutions and private stakeholders so as to implement new rules and new tools in the food sector, so as to reach the target of reducing waste and pollution. Substantial literature on interaction between Millennials and sustainability in the food sector has not yet been developed; the aim of this pioneer study is to offer some contribution to the debate among stakeholders on driving choices towards new consumption rules and production patterns.

Mice that had been given either tap water or 2 ppm lead in their drinking water and either severely food deprived (3 days before testing) or allowed food ad libitum demonstrated significant interactions of lead treatment by day by food condition and lead by block. Although not statistically significant, the food deprived-lead treated mice displayed more errors and longer latencies than the ad libitum-water controls. The food deprived-water controls and ad libitum-lead-treated mice displayed intermediate values. The importance of using multivariate statistical techniques that can evaluate dynamic repeated behavioral measurements is emphasized.
