In classical conditioning, second-order conditioning or higher-order conditioning is a form of learning in which a stimulus is first made meaningful or consequential for an organism through an initial step of learning, and then that stimulus is used as a basis for learning about some new stimulus.
 For example, an animal might first learn to associate a bell with food (first-order conditioning), but then learn to associate a light with the bell (second-order conditioning).
 Honeybees show second-order conditioning during proboscis extension reflex conditioning.
The deadlift is a weight training exercise in which a loaded barbell or bar is lifted off the ground to the level of the hips, then thrown to the ground.
 It is one of the three powerlifting exercises, along with the squat and bench press.
Dopamine dysregulation syndrome (DDS) is a dysfunction of the reward system observed in some individuals taking dopaminergic medications for an extended length of time.
 It typically occurs in people with Parkinson's disease (PD) who have taken dopamine agonist medications for an extended period of time.
 It is characterized by self-control problems such as addiction to medication, gambling, or sexual behavior.
Extended length conditioning (ELC) also known as "end range conditioning" is a type of physical exercise that strengthens the body muscles through a wide range of flexible motions.
 ELC exercises are end range exercises or deep range exercises that contract the muscles from full stretch.
 A typical example of extended length conditioning is the stiffed legged deadlift which is meant for strengthening one of the three posterior thigh muscles referred to as "hamstring".
Sensory preconditioning is a phenomenon discussed using terms common in classical conditioning.
 Procedurally, sensory preconditioning involves first identifying two different neutral stimuli (NS; see neutral stimulus) in relation to a specific unconditioned response (UR) of interest.
 For example, a light (NS1) and a tone (NS2) are common stimuli used in respondent conditioning examples involving salivation; they are not unconditioned stimuli (US) for salivation.
 Next, these two neutral stimuli are paired together repeatedly (e.g., the tone and light are presented simultaneously for a period of time, such as 10 seconds, multiple times).
 The pairing of these two NS constitutes sensory preconditioning.
 However, sensory preconditioning itself is usually followed by repeatedly pairing one of the NS (e.g., the light) with an US (e.g., lemon juice on the tongue to produce salivation) until the light alone elicits salivation.
 To accomplish this, delayed conditioning (see classical conditioning) is generally most effective.
 At this point the light is no longer classified as a NS in relation to salivation; it has become a conditioned stimulus (CS) for salivation.
 Salivation that occurs following the CS is called a conditioned response (CR).
 At this point, the second NS (i.e., the tone noted above) will also elicit salivation even though it has never been paired with the US.
 In short, sensory preconditioning in conjunction with classical conditioning resulted in the tone becoming a CS for salivation (CR).
The transformation is made possible by a centrally located electric motor, which stretches the vehicle with the help of two mechanical screw-and-nut gears by exactly 746 millimetres to its full extended length of 3.74 metres.
 The longitudinal members run on low-friction precision rollers and disappear like a drawer in the rear of the floor pan.
 Despite its variable length the engineers succeeded in designing the adjustable floor pan with the torsional rigidity necessary for a roadster.
 To ensure absolute operational safety the extension mechanism also features self-locking safety latches.
 The car lacks a roof and doors.
A pivot table is a table that summarizes data in another table, and is made by applying an operation such as sorting, averaging, or summing to data in the first table, typically including grouping of the data.
 A trivial example is a column of numbers as the first table, and the column average as a pivot table with only one row and column.
 A slightly less trivial example is a table with columns "sex" and "height", each row giving the sex and height of a person, and a pivot table made from it with the same two columns but only two rows, with "male" and "female" in the "sex" column and the average height of each sex in the "height" column.
 A third more complex and more typical example adds another dimension to the pivot table: a data table has columns "month", "salesman", "product", and "sales", each row giving the total sales of some product by some salesman in a certain month, and a pivot table made from it has a first column "salesman" of salesmen names and the remaining column names are product names and contain the total sales by that salesman of that product over all months.
Cross-promotion is a form of marketing promotion where customers of one product or service are targeted with promotion of a related product.
 A typical example is cross-media marketing of a brand, for example Oprah Winfrey's promotion on her television show of her books, magazines and website.
 Cross-promotion may involve two or more companies working together in promoting a service or product, in a way that benefits both.
 For example, a mobile phone network may work together with a popular music artist and package some of their songs as exclusive ringtones; promoting these ringtones can benefit both the network and the artist.
 Some major corporations, for example Burger King, have a long history of cross-promotion with a range of partners (see Burger King advertising).
 The Disney Channel has also made extensive use of cross-promotion.
 Movie tie-ins are good examples of cross-promotion.
 On occasion, badly planned cross-promotions can backfire spectacularly such as 1992 Hoover free flights promotion fiasco.
A synchronous programming language is a computer programming language optimized for programming reactive systems.
 Computer systems can be sorted in three main classes: (1) transformational systems that take some inputs, process them, deliver their outputs, and terminate their execution; a typical example is a compiler; (2) interactive systems that interact continuously with their environment, at their own speed; a typical example is the web; and (3) reactive systems that interact continuously with their environment, at a speed imposed by the environment; a typical example is the automatic flight control system of modern airplanes.
 Reactive systems must therefore react to stimuli from the environment within strict time bounds.
 For this reason they are often also called real-time systems, and are found often in embedded systems.
A pragmatic clinical trial (PCT), sometimes called a practical clinical trial (PCT), is a clinical trial that focuses on correlation between treatments and outcomes in real-world health system practice rather than focusing on proving causative explanations for outcomes, which requires extensive deconfounding with inclusion and exclusion criteria so strict that they risk rendering the trial results irrelevant to much of real-world practice.
 A typical example is that an anti-diabetic medication in the real world will often be used in people with (latent or apparent) diabetes-induced kidney problems, but if a study of its efficacy and safety excluded some subsets of people with kidney problems (to escape confounding), the study's results may not reflect well what will actually happen in broad practice.
 PCTs thus contrast with explanatory clinical trials, which focus more on causation through deconfounding.
 The pragmatic versus explanatory distinction is a spectrum or continuum rather than a dichotomy (each study can fall toward one end or the other), but the distinction is nonetheless important to evidence-based medicine (EBM) because physicians have found that treatment effects in explanatory clinical trials do not always translate to outcomes in typical practice.
 Decision-makers (including individual physicians deciding what to do next for a particular patient, developers of clinical guidelines, and health policy directors) hope to build a better evidence base to inform decisions by encouraging more PCTs to be conducted.
