Coping with aversive stimulation in the neonatal period: quiet sleep and plasma cortisol levels during recovery from circumcision

Measures of behavioral state and plasma cortisol were obtained on 80 healthy, full-term, 2-3-day-old, male newborns who were scheduled to be circumcised. To establish baseline or precircumcision levels, the newborns were observed, and behavioral state was recorded for the half hour prior to circumcision. Blood was sampled via heelstick for plasma cortisol determination at the end of this observation period. The newborns were then circumcised and assigned randomly to one of 4 postcircumcision, blood-sampling time-point groups. The time points were 30, 90, 120, and 240 min following the beginning of circumcision. Behavioral state was observed during circumcision and for the half hour prior to taking the second blood sample. The results showed a return to baseline cortisol levels sometime prior to 240 min, with data from an additional group of 10 newborns indicating that the return occurred by 150 min. Behavioral distress during circumcision was associated with elevations in plasma cortisol at 30 and 90 min. Quiet sleep was correlated negatively with plasma cortisol prior to circumcision, and significant increases in quiet sleep followed circumcision, with the greatest increase corresponding to the period of most rapid reductions in cortisol.     

Self‐perception of gifts and talents among adults in a longitudinal study of academically talented high‐school graduates

Definitions of giftedness and self‐perceptions of abilities were examined among adults who have been participating in a longitudinal study of academically talented students since their high‐school graduation in 1988. For the present study, participants answered open‐ended questions and completed scales measuring adult giftedness and adult self‐perceptions of abilities in 12 different domains. Gender differences in perceptions were examined. When participants were asked if they believed they were gifted in high school and now, more men than women responded affirmatively to both questions. Further, significant gender differences were identified for perceived competencies in four areas: job competence, nurturance, athletic competence, and morality. Implications of the findings and directions for future research are discussed.

RFID: The Next Serious Threat to Privacy

Radio Frequency Identification, or RFID, is a technology which has been receiving considerable attention as of late. It is a fairly simple technology involving radio wave communication between a microchip and an electronic reader, in which an identification number stored on the chip is transmitted and processed; it can frequently be found in inventory tracking and access control systems. In this paper, we examine the current uses of RFID, as well as identifying potential future uses of the technology, including item-level tagging, human implants and RFID-chipped passports, while discussing the impacts that each of these uses could potentially have on personal privacy. Possible guidelines for RFID’s use, including Fair Information Principles and the RFID Bill of Rights are then presented, as well as technological solutions to personal privacy problems, such as tag killing and blocker tags, as well as simple aluminum foil shields for passports. It is then claimed, though, that guidelines and technological solutions will be ineffective for privacy protection, and that legislation will be necessary to guard against the threats posed by the RFID. Finally, we present what we believe to be the most important legislative points that must be addressed.
