years in applying the theoretical and methodological tenets of Darwinian evolutionary theory to the archaeological record (e.g., Barton and Clark 1997; Dunnell 1980; Lipo et al. 1997, 2005; Lyman and O’Brien 1998; Neiman 1995; O’Brien 1996; O’Brien and Lyman 2000, 2002, 2003a; Shennan 2002; Shennan and Wilkinson 2001). One of the key theoretical tenets of any theory of Darwinian evolution, be i...

Recently, a shortened version of the Zimbardo Time Perspective Inventory (ZPTI; Zimbardo & Boyd, 1999) was proposed as a ‘‘gold standard’’ (Sircova et al., 2014, p. 9). In this study, we examined the internal consistency and structural validity of this version of the ZPTI in samples of adolescents from the United Kingdom (N = 913) and the United States (N = 815), and adults from Australia (N = ...

This paper presents the Dynamic OODA loop, or DOODA loop for short, a generic model of Command and Control (C2) stemming from Boyd’s OODA loop and cybernetic models of C2. The DOODA loop is formulated in terms of functions that must be accomplished for effective C2, and these functions are then studied in terms of (partially overlapping) processes. The DOODA loop preserves the prescriptive rich...

Height is directly associated with mortality from cancer, but the explanation for this association is unclear. Whereas adult height is a marker of nutrition and health throughout childhood, most growth before puberty is due to increases in leg length. Leg length can therefore be used as a marker for exposures that generate the association between adult height and cancer. 2 We examined the assoc...

We continue our analysis of higher and multiple Mahler measures using log-sine integrals as started in [7, 8]. This motivates a detailed study of various multiple polylogarithms [4] and worked examples are given. Our techniques enable the reduction of several multiple Mahler measures, and supply an easy proof of two conjectures by Boyd.

In our recent work with M. Rogers on resolving some Boyd’s conjectures on two-variate Mahler measures, a new analytical machinery was introduced to write the values L(E, 2) of L-series of elliptic curves as periods in the sense of Kontsevich and Zagier. Here we outline, in slightly more general settings, the novelty of our method with Rogers, and provide a simple illustrative example. Throughou...
