Lower Cortisol Activity is Associated with First-Time Driving while Impaired

Driving while impaired (DWI) is a grave and persistent high-risk behavior. Previous work demonstrated that DWI recidivists had attenuated cortisol reactivity compared to non-DWI drivers. This suggests that cortisol is a neurobiological marker of high-risk driving. The present study tested the hypothesis that this initial finding would extend to first-time DWI (fDWI) offenders compared to non-DWI drivers. Male fDWI offenders (n = 139) and non-DWI drivers (n = 31) were exposed to a stress task, and their salivary cortisol activity (total output and reactivity) was measured. Participants also completed questionnaires on sensation seeking, impulsivity, substance use, and engagement in risky and criminal behaviors. As hypothesized, fDWI offenders, compared to non-DWI drivers, had lower cortisol reactivity; fDWI offenders also showed lower total output. In addition, cortisol activity was the most important predictor of group membership, after accounting for alcohol misuse patterns and consequences and other personality and problem behavior characteristics. The findings indicate that attenuated cortisol activity is an independent factor associated with DWI offending risk at an earlier stage in the DWI trajectory than previously detected.

A physically based trunk soft tissue modeling for scoliosis surgery planning systems

One of the major concerns of scoliotic patients undergoing spinal correction surgery is the trunk's external appearance after the surgery. This paper presents a novel incremental approach for simulating postoperative trunk shape in scoliosis surgery. Preoperative and postoperative trunk shapes data were obtained using three-dimensional medical imaging techniques for seven patients with adolescent idiopathic scoliosis. Results of qualitative and quantitative evaluations, based on the comparison of the simulated and actual postoperative trunk surfaces, showed an adequate accuracy of the method. Our approach provides a candidate simulation tool to be used in a clinical environment for the surgery planning process.

The comparison of vestibular functions in hearing and hearing impaired populations

This study investigates possible vestibular dysfunctions in the deaf using a typical clinical assessment battery and discerns whether there is a trend between these disorders in meningitic children as compared to children with unknown origins of deafness.

Helpful information for parents of newly diagnosed hearing-impaired children

This paper presents an information booklet for parents of newly diagnosed hearing-impaired children. The booklet provides basic supplemental information to aid parents in understanding hearing impairment, audiologic information, and educational options. Topics covered include audiograms, educational methods, hearing aids, cochlear implants, informational resources, communication strategies, and hearing health-care specialists.

The clinical evaluation of language functions (CELF): its applicability for hearing-impaired children

This paper discusses the diagnostic battery of the CELF in terms of construct validity and in administration of subtests.

Assessing phonemic awareness skills in hearing impaired students

This paper discusses phonemic awareness and its role in providing appropriate literacy instruction to both hearing and hearing impaired children. The ability of hearing-impaired students to gain phonological awareness skills is examined and instructional models for teaching phonological and phonemic awareness skills are presented. Also included is a checklist to be used to assess phonological and phonemic awareness skills in hearing-impaired students.

Applicability of the Test of Visual Perceptual Abilities (TVPA) in diagnosing learning disabilities in hearing-impaired children

This paper studies the validity of the Test of Visual Perceptual Abilities (TVPA) as an indicator of learning problems in hearing-impaired children and how it correlates with other measures of learning disabilities.
