Experiments on blue jays suggest they form a search image for certain prey.. Visual predators may form what is termed a search image of certain prey.. Predators need not locate their host directly: Kestrels, for instance, are able to detect the faeces and urine of their prey (which reflect ultraviolet), allowing them to identify areas where there are large numbers of voles, for example.
Anti-predator adaptation in action: the kitefin shark (a–c) and the Atlantic wreckfish (d–f) attempt to prey on hagfishes. First, the predators approach their potential prey. Predators bite or try to swallow the hagfishes, but the hagfishes have already projected jets of slime (arrows) into the predators' mouths.
Marketing mix modeling (MMM) is an analytical approach that uses historic information to quantify impact of marketing activities on sales. Example information that can be used are syndicated point-of-sale data (aggregated collection of product retail sales activity across a chosen set of parameters, like category of product or geographic market) and companies’ internal data.
The marketing mix has been defined as the "set of marketing tools that the firm uses to pursue its marketing objectives in the target market". [2] Marketing theory emerged in the early twenty-first century. The contemporary marketing mix which has become the dominant framework for marketing management decisions was first published in 1984.

A theory for the evolution of aposematism posits that it arises by reciprocal selection between predators and prey, where distinctive features in prey, which could be visual or chemical, are selected by non-discriminating predators, and where, concurrently, avoidance of distinctive prey is selected by predators.
Bayesian decision theory can be applied to all four areas of the marketing mix. [11] Assessments are made by a decision maker on the probabilities of events that determine the profitability of alternative actions where the outcomes are uncertain. Assessments are also made for the profit (utility) for each possible combination of action and event.
A frequent choice of bait and prey domains are residues 263–352 of yeast Gal11P with a N342V mutation [2] and residues 58–97 of yeast Gal4, [2] respectively. These domains can be used in both yeast- and bacterial-based selection techniques and are known to bind together strongly. [1] [2]
The term Marketing research mix (or the "MR Mix") was created in 2004 and published in 2007 (Bradley - see references). It was designed as a framework to assist researchers to design or evaluate marketing research studies. The name was deliberately chosen to be similar to the Marketing Mix - it also has four Ps.
