In this study livestock distribution on the landscape was mapped during two seasons, summer and winter, for two years to determine where livestock congregate and to model factors that influence livestock distribution. Two small herds of cows were observed in separate range units on the San Joaquin Experimental Range for a total of twenty-four 24-hour observation periods to ascertain daily movem...
BACKGROUND This study was a full-year investigation of whether children, who had previously been trained to cooperate and help each other, were able to use these behaviours in reconstituted groups without additional training one year later. AIMS (i) To examine whether children who have previously been trained to cooperate demonstrate more cooperative and helping behaviours in their groups tha...
We report the clinical features of the original Chilean family with Kufor-Rakeb syndrome (KRS) that led to the discovery of the ATP13A2 gene at the PARK9 locus. KRS is a rare juvenile-onset autosomal recessive disease characterized by progressive Parkinsonism, pyramidal signs, and cognitive decline in addition to vertical gaze palsy and facial-faucial-finger minimyoclonus. Neurological and neur...
PURPOSE Human eye-movement recordings have documented that surgical treatment of congenital nystagmus (CN) also produces a broadening of the null zone and changes in foveation that allow increased acuity. We used the achiasmatic Belgian sheepdog, a spontaneously occurring animal model of human CN and see-saw nystagmus (SSN), to test the hypothesis that changes induced by surgical interruption o...
In two prior papers in our series on qualitative research [Frankel & Devers (2000a, 2000b) Qualitative research: a consumer's guide, Education for Health, 13, 113-123; Frankel & Devers (2000) Study design in qualitative research-1: developing research questions and assessing research needs, Education for Health, 13, 251-261], we examine two critical issues in qualitative research design: sampli...
This work analyzes patterns and factors in workzone crashes. In response to actual and suspected deficiencies in the quality of workzone crash reporting from standard police crash reports, an enhanced crash report form and procedure was developed and applied by police agencies in a small sample of workzones in Illinois. Analysis of 110 workzone crashes revealed differences between what the poli...
OBJECTIVE To explore the use of an observational, cognitive-based approach for differentiating between successful, suboptimal, and failed entry of coded data by clinicians in actual practice, and to detect whether causes for unsuccessful attempts to capture true intended meaning were due to terminology content, terminology representation, or user interface problems. DESIGN Observational study...
BACKGROUND Thoracic cirtometry is a simple and accessible technique to evaluate chest mobility during forced breathing. However, it does not allow for the assessment of compensatory movements commonly used by people with chronic diseases, such Duchenne muscular dystrophy (DMD). DMD is a condition characterized by progressive and irreversible degeneration of the musculoskeletal system. OBJECTI...
BACKGROUND Recently, pilot studies from our laboratory have shown that dental surfaces may be discriminated by the analysis of tip oscillations of an ultrasonic instrument, which possesses computerized calculus-detection features. For the evaluation of this smart detection system, its surface recognition qualities are of crucial importance. For in vivo studies, however, it proved to be difficul...
BACKGROUND In young children with type 1 diabetes mellitus (T1DM), parents have complete responsibility for the diabetes-management. In toddlers and (pre)schoolers, the tasks needed to achieve optimal blood glucose control may interfere with normal developmental processes and could negatively affect the quality of parent-child interaction. Several observational instruments are available to meas...
