Flexibility and uncertainty in the housing market

This paper provides one reason why the level of trading in the housing market is volatile. We show that when uncertainty is high and can be expected to be resolved in the near future, both buyers and sellers have an incentive to postpone trading until uncertainty has been resolved. In the model, agents trade in the housing market either now, when there is uncertainty concerning the future tax rule for house owners, or later, when this uncertainty has been resolved. Under the assumption of risk neutrality (and high transaction costs), we show that any rational expectations equilibrium involves all trading being postponed. When agents are risk averse, this result holds less generally; we show that it does hold when changes in the tax rule are expected not to affect the future price of houses too strongly.     

Accuracy of eyewitness identifications in showups and lineups

Experiment 1 tested one-person and six-person photographic lineup identifications in field situations either immediately, or 30 minutes, or 2 hours, or 24 hours after a 15-second ordinary encounter with a target. Accuracy of performance was superior in six-person lineups than in showups over time. False identifications of a lookalike innocent suspect were significantly greater in showups than in six-person lineups, especially when the suspect wore the same clothing as the culprit. Experiment 2 followed the same research design as Experiment 1, except that only live showup identifications were tested and, in addition, a physically dissimilar innocent suspect was shown to witnesses. The dissimilar innocent suspect was consistently and correctly rejected in the target-absent showup. Hit rates for live suspects were relatively low over the 24-h retention interval. Correct rejections significantly exceeded false identifications only on the immediate test. The lookalike innocent suspect was readily rejected when different clothing was worn at the test. No significant differences were found in hit scores or in confidence-accuracy scores between live and photographic targets. Confidence-accuracy correlations were significant but low across experimental conditions.     

DoD technology for commercialization: Sharing the wealth means spreading the word

The fortunes of information transfer and technology are inextricably bound. The extent to which technology transfer is accomplished depends largely on the effectiveness, selectivity, and efficiency with which information is transferred. This article reviews DoD agents that bring about the transfer of its information; in doing so, they contribute to the transfer of DoD’s technology to state and local governments and to the private sector. It emphasizes the role played by the Defense Technical Information Center.     

The Severity of Violence Against Men Scales

In response to the need to differentiate the effects of female and male violence, scales were developed applicable to female violence against men. Two versions of the Severity of Violence Against Men Scale (SVAMS) were devised as a counterpart to the Severity of Violence Against Women Scales (SVAWS). On 10-point rating scales, college males (N = 570) rated how serious, aggressive, abusive, violent, and threatening it would be if a woman did each of 46 acts to a man. The mean of each act across the ratings was calculated and then submitted to factor analysis. Eight factors emerged representing threats of mild, moderate, and serous violence, actual mild, minor, moderate, and serious violence and sexual violence. Community men (N = 115) rated the same acts on seriousness, aggressiveness, and abusiveness. All factors were unidimensional. Second order factor analysis confirmed that two dimensions (physical threats and actual violence) were represented. In contrast to the SVAWS, sexual violence loaded with threats of physical violence. The groups' ratings of physical and emotional harm provided the weightings for future research with student (SVAMS-S) and adult (SVAMS) samples.

One hundred seventy two deaths involving the use of oxycodone in Palm Beach County

Oxycodone is a potent semi-synthetic narcotic prescribed for the management of pain. Previous investigators have reported that the abuse of oxycodone is most frequently seen in conjunction with the abuse of other drugs, although fatalities have been reported with oxycodone alone. We undertook a retrospective review of cases investigated by the Palm Beach County Medical Examiner's Office in which postmortem toxicologic studies indicated the presence of oxycodone. A total of 172 consecutive cases were studied, including 18 in which death was attributed to oxycodone toxicity, 117 to combined drug toxicity, 23 to trauma, 9 to natural causes and 5 to another drug or drugs. The postmortem blood concentrations of oxycodone overlapped among the groups. The mean blood oxycodone concentration among the cases of oxycodone toxicity was 0.69 mg/L, combined drug toxicity 0.72 mg/L and trauma 0.62 mg/L. Concentrations were lower in cases of deaths attributed to natural causes and to another drug or drugs (mean each 0.087 mg/L). Benzodiazepines, detected in 96 cases, were the most common co-intoxicants in the cases of combined drug toxicity, followed by cocaine, which was found in 41. The most frequently encountered benzodiazepine was alprazolam. This study confirms that deaths in which oxycodone is a factor are most commonly cases of combined drug toxicity. The high incidence of alprazolam as a co-intoxicant has not been previously recognized.
