Using a nationally representative sample of American married or cohabiting women, this prospective study examined women who reported or denied intimate partner violence (IPV) at wave 1 and compared them on a range of psychosocial outcomes at a 5-year follow-up. This study also examined the rate of divorce or separation during the 5-year interval among women who reported IPV at wave 1 and explored whether certain predictors were related to ending an abusive relationship with an intimate partner during the period. Women with IPV at wave 1, compared to women without IPV, were significantly more likely to experience a greater degree of depressive symptoms and functional impairment and less self-esteem and life satisfaction at the 5-year follow-up. Also, nearly half of the women in an abusive relationship left the relationship within the period. Leaving the abusive relationship was associated with lower individual income and more social support at wave 1. 相似文献

- Being in the public eye puts pressure on an organization's Public Affairs (PA) function. This study finds that firms more closely covered by the press tend to be more forceful in promoting their own position on social issues (social buffering). Press coverage is not associated with greater corporate efforts to comply with societal expectation (social bridging). Overall, press coverage is weakly associated with lowered perceived corporate public affairs performance.

The computer automated scanning electron microscope. X-ray microanalysis of Firearms Discharge Residue (FDR) can reveal substantial information about the circumstances of their generation beyond the presence of characteristic gunshot residue (GSR). Indicators of the type of weapon and ammunition used can he obtained from the distribution of GSR particle shapes and from the multi-element analysis of the FDR sample. This is demonstrated for a large database of GSR samples from nine different handguns and over 60 different ammunitions. An example classification scheme is presented for the supporting particles generally found present in FDR. When particle type area concentration ratios are normalized to the iron (Fe) particle type, results show it is possible to distinguish much about the metal used in the weapon manufacture, whether it was of large or small caliber, whether the bullets were jacketed or plated, and whether the cartridge cases were of aluminum, brass, or nickel-plated brass. Standardization of such analytical schemes would be advantageous. 相似文献

Bacterial infection due to Bartonella henselae commonly develops in children and young adults following cat/dog contacts and/or cat/dog scratches. Regional lymphadenopathy is its most common clinical expression. However, encephalitis and Parinaud's syndrome (oculoglandular syndrome) have also been reported as has systemic illness. A review of the international literature in all languages revealed no fatal complications in immunocompetent hosts. A four-year-old white child with no underlying illness began to have seizure-like activity. She was taken to a local hospital and subsequently transferred to a medical center. The child was treated aggressively for seizures and fever of unknown origin. However, her condition rapidly declined and she died without a specific diagnosis. At autopsy there was marked cerebral edema with no gross evidence of acute meningitis. Microscopic exams revealed multiple granulomatous lesions as well as a meningitis and encephalitis. A variety of cultures and stains were negative for acid fast and fungal organisms. Warthin-Starry stains of involved tissue including brain and liver revealed pleomorphic rod shaped bacilli consistent with Barronella henselae. Analysis of brain tissue with polymerase chain reaction (PCR) and Southern blot for the deoxyribonucleic acid (DNA) was definitive for DNA of Bartonella henselae bacteria. 相似文献
