Cognitive variability
… flexibility, fluidity, rigidity, perseveration, variability, and other similar terms. Generally, all these terms have refenced to the idea that the behaviour of people in different situations or of different people in the same situation··, varies along a continuum marked at one end by extreme …

Is variability appropriate? Encoding Variability and Transfer-Appropriate Processing
… function, we propose that increased encoding variability – increasing the range of encoded cues – increases the likelihood of TAP when the retrieval scenario is unknown. The larger the set of encoded cues, the more likely those cues will recur during retrieval and therefore achieve TAP. …

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.
Previous research has shown that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six …

Physical Activity, Heart Rate Variability, Sleep Parameters, and Glycemic Variability in T1D
… individuals with type 1 diabetes (T1D), glycemic variability (GV), beyond mean glucose levels, is a critical determinant of cardiovascular risk and long-term complications. Although physical activity and sleep are key behavioral factors influencing glycemic control, prior research has largely …

Soil Spatial Variability: Structures, Models, and Their Effects on Crop Yield Variability
… accounted for more than 80% of total soil variability. Component regression accounted for about 52%, and 39% of soybean and corn yields variability respectively. Particle size distribution and organic matter by influencing moisture and nutrient dynamics, were the most important factors …

Evolving Variability Tolerant Logic
Intrinsic variability occurs between individual MOSFET transistors caused by atomic-scale differences in the construction of devices. The impact of this variability will become a major issue in future circuit design as the devices scale below 50nm. In this thesis, the background to the causes and …

Aging, Gait Variability, and Adaptability
… the relationships between age, measures of gait variability, and locomotor adaptability. Measures of gait variability are used to identify maladapted locomotor behavior, motor disease, and risk of falls. The first aim was to determine the relationships between age and measures of gait …

Sociolinguistic variability in oral narrative.
This thesis begins with a sociolinguistic correlational study of three phonetic variables - (h), (t) and (ing) - as used by four occupational groups - nurses, chefs, hairdressers and taxi-drivers. The groups were selected to incorporate three independent variables: sex (male-dominated versus …

Rainfall variability over southern Africa
… Africa is subject to high inter annual rainfall variability and the factors influencing southern African rainfall are not fully understood. The variability has been linked with various sea surface temperature anomalies (SSTAs) in each of the three major ocean basins as well as variability in the …
