Preventing Child Sexual Abuse: Screening for Hidden Child Molesters Seeking Jobs in Organizations That Care for Children.

Approximately 10% of children and adolescents are sexually abused by adults caring for them outside the home. The current study tested the validity and reliability of a child protection screen to identify job applicants who pose a sexual risk to children. The screen uses three separate measures.

Viral infection of cells in culture detected using infrared microscopy.

FTIR microscopy has been used to collect spectra for uninfected (mock) Vero cells, and cells that have been infected with herpes simplex virus type 1 (HSV-1) and human adenovirus type 5 (Ad-5). Cells were infected at a multiplicity of infection of 10, and studied at 24 hours post exposure. The spectra for infected samples display many differences compared to the spectra for uninfected samples.

Assessing cortisol reactivity to a linguistic task as a marker of stress in individuals with left-hemisphere stroke and aphasia.

Purpose: In this study, the authors explore a method of measuring physiologic and perceived stress in individuals with aphasia by investigating salivary cortisol reactivity and subjectively perceived stress in response to a standardized linguistic task.

Method: Fifteen individuals with aphasia and 15 age-matched healthy controls participated in a linguistic task involving speaking to an unfamiliar listener and a nonlinguistic task consisting of the Mirror Drawing Test (Starch, 1910). Salivary cortisol samples were taken following a 30-min baseline period, at the beginning and end of each task, and at 10-min intervals throughout the posttask period.

New confidence intervals for the difference between two sensitivities at a fixed level of specificity.

For two continuous-scale diagnostic tests, it is of interest to compare their sensitivities at a predetermined level of specificity. In this paper, we propose three new intervals for the difference between two sensitivities at a fixed level of specificity. These intervals are easy to compute.
