Marijuana Demand: An Instrumental Variable Approach
… marijuana demand is endogenous by utilizing an instrumental variable technique. Findings are consistent with previous research and suggest that the own-price elasticity of demand for marijuana is inelastic and approximately -0.6. Estimates also point to the conclusion that contrary to recent …

Instrumental conditioning and learning in Poroderma Pantherinum
… by using a series of food-reward tests based on instrumental conditioning. A target with black and white stripes was used as the discriminative stimulus, while an auditory cue acted as a bridging stimulus for the food-reward task. Sharks were collected by hand whilst diving and shore-angling in …

The effect of instrumental timbre preference and instrumental timbre on the pitch error detection skills of university conducting students
… of this study was to determine the effect of instrumental timbre preference and instrumental timbre on the error detection skills of undergraduate conducting students. The study sought to answer two specific questions: Is timbre preference, as determined by Gordon's (1984) <u>Instrumental …

A Mathematical Model for Type II Instrumental Discriminations
Using the same assumptions found in the Trabasso & Bower (1968) mathematical model for type I and relevant redundant cue (RRC) discriminations, a mathematical model was proposed for type II discriminations. A type I discrimination has one relevant cue. An RRC discrimination has two relevant cues, …

Incidence of musculoskeletal problems among instrumental music students
The incidence of musculoskeletal problems amongst instrumental music students in Australia is unknown. This study examined students who play musical instruments and are potentially at risk of developing problems, including pain and injury, related to their play activities. Full-time instrument …

Controlled and automatic processes in Pavlovian-instrumental transfer
… that underpin human outcome-selective Pavlovian-instrumental transfer (PIT) effects. PIT reflects the capacity of a Pavlovian stimulus to selectively potentiate an instrumental response that predicts a common rewarding outcome. PIT effects are often suggested to reflect a relatively automatic …

Lifting Failed Sanctions: Alliances, Reputations, and Instrumental Deference
… damage of abandoning sanctions. I call this instrumental deference: the strategic yielding to allied demands to preserve alliance relationships while limiting reputational harm. To test these expectations, I employ a multi-method research design. First, I construct an original dataset of …

Neural Mediation of Instrumental Learning and Concurrent Discrimination
… described here examined the neural mediation of instrumental discriminative learning. A great deal is known about the neural circuitry mediating discriminative avoidance learning, wherein rabbits learn to step in an activity wheel in order to avoid a footshock following one tone conditional …

Semiparametric instrumental variable methods for causal response models
This dissertation proposes new instrumental variable methods to identify, estimate and test for causal effects of endogenous treatments. These new methods are distinguished by the combination of nonparametric identifying assumptions and semiparametric estimators that provide a parsimoniuous summary …

Aircraft simulation validation using an instrumental variable approach
… proposed validation procedure is based on the instrumental variable parameter identification method. The instrumental variable method requires a choice of "instruments." For this research, the "instruments" are chosen using the response predicted by an available simulation model. With the …

Climate Responsibility : The Instrumental Rationales of Private Oil Companies
… will not exceed 2°C. The study underlines that instrumental factors can explain the forms of corporate climate responsibility. However, the study does not exclude institutional, relational, nor philanthropic reasons for climate responsibility. This study discusses broad instrumentalism, which …

Mediodorsal thalamus contributes to the timing of instrumental actions
<p>Interval timing relies on a widely dispersed network of cortical and subcortical brain regions. Despite increasing evidence emphasizing the integrative role of the thalamus in cognition, its contribution to timing behavior is poorly understood. Anatomically connected to brain regions within the …

The role of frontal-striatal circuits in instrumental behaviour
… of area 11 apparently enhanced sensitivity to instrumental contingency degradation, possibly by blocking competing pavlovian associations. Manipulations of area 14, 25 or area 32 did not affect sensitivity, indicating the neuroanatomical specificity of the contingency degradation deficits. …
