Methods based on Rate Distortion theory have been successfully used to cluster stimuli and neural responses in order to study neural codes at a level of detail supported by the amount of available data. They approximate the joint stimulus-response distribution by quantizing paired stimulus-response observations into smaller reproductions of the stimulus and response spaces. An optimal quantization is found by maximizing an information-theoretic cost function subject to both equality and inequality constraints, in hundreds to thousands of dimensions. This analytical approach has several advantages over other current approaches:
- it yields the most informative approximation of the encoding scheme given the …

Objectives: This study examined the relationship between substance use disorder (SUD) and intimate partner violence screening (IPV) and management practices in the emergency department (ED). Methods: This was a retrospective cohort study of adult ED patients presenting to an urban, tertiary care teaching hospital over a 4-month period. An automated electronic data abstraction process identified consecutive patients and retrieved visit characteristics, including results of three violence screening questions, demographic data, triage acuity, time of visit, and ICD-9 diagnosis codes. Data on management were collected using a standardized abstraction tool by two reviewers masked to the study question. Multivariate logistic regression …

Systems Science Friday Noon Seminar Series
The Oregon Center for Aging and Technology (ORCATECH) seeks to facilitate successful aging and reduce the cost of healthcare by establishing the evidence base for technologies supporting aging-in-place research and care. This is done through pilot studies evaluating the role of the technologies, as well as large longitudinal studies in which sensors are placed in the homes of community-dwelling elders to monitor daily patterns of activity, walking speeds, medication adherence, and other behaviors. These sensors collect continuous data that reflect normal variability in behaviors as well as trends that may indicate problematic changes in cognition or mobility. Because data are …

Objective—To identify neuromuscular, balance and vision factors that contribute to falls in recently treated breast cancer survivors (BCS) and explore links between fall risk factors and cancer treatment
Design—Case-control plus prospective observation
Setting—Comprehensive cancer center
Participants—BCS within two years chemotherapy completion and/or on adjuvant endocrine therapy (N=59; mean age: 58 yrs)
Intervention—not applicable
Main outcome measures—Objective measures of postural control, vision and neuromuscular function included 1) a sensory organization test (SOT), 2) a visual assessment battery, 3) muscle mass by DXA, and 4) neuromuscular function with strength by repetition maximum, power by timed stair …
