Hazards of mattresses, beds and bedding in deaths of infants 总被引:2,自引:0,他引:2

Of 52 infants who had died suddenly and were referred to autopsy, nine had lain on adult water beds for the first time; five had died as a result of accidents; two had died on water beds; two were in beds with widely spaced slats; and one had died as a result of strangulation. Three deaths were due to overlying. Three other infants had been placed on sheepskin rugs for the first time and were found dead shortly thereafter. These infants ranged in age from 2 to 9 months, except for a severely mentally retarded nine-year-old with spastic paraplegia. We believe that a general warning should be issued concerning water beds and that soft bedding should not be used for infants. Infants should not be placed unattended or left to sleep on water beds; only beds recommended for infants should be used. Overlying of a young infant is most likely to occur on a water bed, or if the parent is obese or has consumed alcohol. 相似文献

Three questions relevant to insanity decisions were examined: (a) What informational cues are weighed most heavily in the attribution of criminal responsibility? (b) How do verdict forms influence these attributions? And (c) How do individuals' beliefs about insanity and responsibility influence decision making? Undergraduate subjects (n=181) responded to vignettes portraying an act by a mentally disordered defendant. Psychiatric jargon was avoided, so that attributions were not a function of diagnostic terminology. It was found that, under the traditional scheme of not guilty by reason of insanity (NGRI) vs. guilty, level of mental disorder (schizophrenia vs. personality disorder) was the primary determinant of insanity decisions. Also, insanity judgments were more likely to be made for acts performed without planful intentionality. Under the alternative scheme of NGRI vs. guilty but mentally ill (GBMI) vs. guilty, mental disorder still controlled NGRI verdicts; a bizarre act increased the likelihood of a GBMI over a guilty verdict; and the GBMI verdict option reduced markedly the proportion of psychotic defendants found NGRI and the proportion of personality disordered defendants found guilty. There were no significant differences between diagnostic groups in the likelihood of being found GBMI. Most subjects preferred to utilize the GBMI option as a compromise verdict even in the face of very severe mental illness. Attitudinal data revealed considerable variation in agreement with the classic moral logic of the insanity defense and accounted for a significant amount of the variance in insanity decisions. The implications for both social policy and future research are discussed. 相似文献

Death associated with inadvertent hydrocodone overdose in a child with a respiratory tract infection
A 3-year-old child died of the combined effects of a bacterial superinfection and a relative overdose of hydrocodone prescribed for a cough due to a presumed viral respiratory tract infection. This case illustrates the importance of evaluating the effects of prescribed medication in assessing the cause and mechanism of death in children dying suddenly of presumed natural disease. 相似文献

This paper examines race-based peremptory challenges. Such challenges occur during the voir dire jury selection process. The process allows both the defense and the prosecution to strike jurors who they believe will not
decide cases fairly. However, in the case of Batson v. Kentucky 476 U.S. 79 (1986), the Supreme Court ruled that race could not be used as a factor in eliminating prospective jurors. This
paper examines federal litigation for five years in which it was alleged that race was used as a factor in removing a juror.
An examination of the cases revealed that most of the cases involved sole male litigants who allege that there were multiple
race-based peremptory challenges used in their cases. Moreover, most of the cases that led to the allegations involved violent
offenses. Other case characteristics are noted, but of most significance was the finding that most appellants lost their cases.
As such, the courts felt that most of the challenges were, in fact, race neutral. The implications of this research are discussed.

This study evaluated the use of different degree day (DD) models, developmental thresholds and developmental data sources for estimating postmortem interval (PMI) based on developmental rates of blow flies (Diptera: Calliphoridae). Blow fly evidence was collected from three mock crime scenes and sent for blind analysis of PMI. PMI estimates were calculated using averaging, single sine, double sine, single triangle, and double triangle models of DD calculation with minimum developmental thresholds of 0, 6 and 10 °C and Anderson's, Byrd and Allen's, Greenberg's, Nishida's and Kamal's developmental data sets. These estimates were compared with the actual PMI to determine which combination of DD model, developmental threshold and developmental data provided the most accurate estimate. For all three cases, at least one method gave a PMI estimation that was within 1 day of the actual date of death. There was no variability between PMI estimated using the five models of DD calculation. Overall, as lower developmental threshold increased, the PMI interval estimates increased. Depending on the developmental data set used, increasing the lower developmental threshold caused some overestimations of the date of oviposition, with estimates given that were prior to the actual death. Future PMI estimates should include error ranges, so that overestimation of PMI is avoided. 相似文献

Current forensic DNA profiling methods rely on the analysis of samples at specialised laboratories with an average turnaround time of several days. The ability to rapidly determine a partial profile of short tandem repeats at the point-of-arrest would be of great benefit to police forces around the world, for example enabling a suspect to be rapidly included or excluded from an investigation. We have developed a homogeneous PCR method for the interrogation of STR loci utilising fluorescent oligonucleotide probes and melting curve analysis. Alleles of the D18S51, TH01 and D8S1179 loci were differentiated and identified on the basis of target length and probe melting temperature. Assay performance was evaluated by comparing melting peak data with the AmpFlSTR® SGM Plus® system. The method is compatible with direct analysis of unpurified buccal swab samples, enabling a partial STR profile to be generated within 1 h. 相似文献

At least one‐quarter of covered workplaces violated the parental leave requirements of the Family and Medical Leave Act of 1993 (FMLA) when surveyed in 1997. What explains this noncompliance? Using a survey of 389 U.S. workplaces and qualitative interviews with managers in 40 organizations, I demonstrate that noncompliance comes in distinct forms. Some forms of noncompliance result from a failure to update institutionalized—and gendered—policies, practices, and norms. This form of noncompliance (indicated by illegally short leaves) is better explained by the institutional perspective, while outright noncompliance (as evidenced by a lack of leaves) is best explained by rational choice and deviant culture theories. 相似文献
