The aim of the social and behavioral sciences is to understand human behavior across a wide array of contexts. Our theories often make sweeping claims about human nature, assuming that our ancestors or offspring will be prone to the same biases and preferences. Yet we gloss over the fact that our research is often based in a single temporal context with a limited set of stimuli. Political and moral psychology are domains in which the context and stimuli are likely to matter a great deal (Van Bavel, Mende-Siedlecki, Brady, & Reinero, 2016). In response to Yarkoni (see BBS issue), we delve into topics related to political and moral psychology that likely depend on features of the research. These topics include understanding differences between liberals and conservatives, when people are willing to sacrifice someone to save others, the behavior of political leaders, and the dynamics of intergroup conflict.

The correlation between ATP concentration and bacterial burden in the patient care environment was assessed. These findings suggest that a correlation exists between ATP concentration and bacterial burden, and they generally support ATP technology manufacturer-recommended cutoff values. Despite relatively modest discriminative ability, this technology may serve as a useful proxy for cleanliness.

Pick's disease most commonly begins in the midlife period. Sjogren, Sjogren and Lindgren (1952) in their series of 18 anatomically verified cases of Pick's disease found that the average age of onset was 54·5±2·7 years. Escourolle (1956) segregated from the literature 184 cases in which he considered the diagnosis of Pick's disease to be “indisputable” and demonstrated therefrom that the sixth decade is the period of highest incidence. Pick's disease, however, has frequently been reported to erupt in the seventh decade and occasionally in the eighth, ninth and tenth decades. (Bonfiglio, 1926; von Braunmühl, 1928; Moyano, 1932; Sjogren, Sjogren and Lindgren, 1952.)

The aim of this paper is to show how, in our view, the diagnosis of Pick's pre-senile dementia can be made in some cases during life on clinical grounds alone.
