Does ink age inside of a pen cartridge?

In questioned document examination and ink dating, it has been assumed that the ink inside of a pen cartridge does not begin aging until the ink is dispensed onto paper. Positive ion laser desorption (LD) mass spectra were obtained of ink-on-paper samples containing methyl violet, from new and old pens. Mass spectral studies with methyl violet have established the mechanism for how the dye degrades over time, and have provided structural information concerning the dye's degradation products. This information was used as an indication of the relative age of ink on paper. The LD mass spectrum of the ink from a new pen was indicative of "new" ink, whereas the spectra of the ink found in some older pens may appear to be either new or old. The ink from most of the old pens studied appears not to have aged, supporting the common assumption, whereas other ink samples produced "aged" ink spectra, suggesting otherwise.     

Sudden and unexpected death resulting from splenic artery aneurysm rupture: two case reports of pregnancy-related fatal rupture of splenic artery aneurysm

Rupture of a splenic artery aneurysm is a rare and usually catastrophic event, most commonly associated with pregnancy. In spite of increasingly common reliance on abdominal angiography, magnetic resonance imaging, and computerized tomography during the past quarter century, clinicians uncommonly recognize any of the various splanchnic arterial aneurysms absent premonitory signs or symptoms. Accordingly, rupture of a visceral aneurysm, including splenic artery aneurysm, typically presents as sudden, unexpected obtundation or death. As a consequence, the initial recognition and diagnosis of splenic artery aneurysm rupture take place only at autopsy. This report presents two such cases of sudden death resulting from splenic artery aneurysm in a pregnant woman and a postpartum woman, respectively.     

Sudden unexpected death in epilepsy: neuropathologic findings

Sudden unexpected death in epilepsy refers to sudden death of an individual with a clinical history of epilepsy, in whom a postmortem examination fails to uncover a gross anatomic, toxicologic, or environmental cause of death. Evidence of terminal seizure activity may not be present. One to two percent of natural deaths certified by the medicolegal death investigator are attributed to epilepsy. Detailed microscopic examination of the brain has increasingly afforded the identification of structural changes representative of epileptogenic foci. The authors present 70 cases of death attributed to sudden unexpected death in epilepsy. These cases were classified as follows: individuals who lacked a gross brain lesion, those who had a brain lesion demonstrable at autopsy, and those who lacked neuropathologic evaluation because of decomposition or because only an external examination was done. All of the subjects had a clinical history of seizures. The authors confirm that various microscopic findings, including neuronal clusters, increased perivascular oligodendroglia, gliosis, cystic gliotic lesions, decreased myelin, cerebellar Bergmann's gliosis, and folial atrophy, are present in a higher percentage of the brains of sudden unexpected death in epilepsy subjects than in the brains of age- and sex-matched control subjects.     

The evolution of a campaign: tracking press coverage and party press releases through the 2001 UK General Election

• This paper builds upon a content analysis of all news articles that appeared in six national daily newspapers and of all national press releases issued by the three main political parties during the UK General Election 2001 campaign. The results were compared with data from two opinion polls conducted at the start and at the end of the campaign. Here, using the same basic data, we track the coverage of issues in party press releases and daily newspapers on a weekly basis to determine how the parties' priorities and press coverage evolved.
• The results show that the Labour and Liberal Democrat campaign strategies, in terms of relative issue priorities, did not change during the campaign. However, the Conservatives shifted their attention to the public priorities of Health and Education towards the end of the campaign. There is evidence that the Conservative emphasis on Europe and taxation earlier in the campaign may have influenced the volume of press coverage but did not appear to have affected relative party standings. The implications of these results for political marketers are considered.

Explaining Ethnic Autonomy Regimes in Latin America

Through a systematic examination of nine cases, the author identifies factors that enabled indigenous movements in five Latin American countries to secure formal recognition of politico-territorial autonomy regimes. All nine cases occurred within the framework of a larger regime bargain—either (1) peace talks intended to end armed struggle when the regime faced a serious challenge to maintain political order or territorial control, or (2) a severe crisis of legitimacy and governability that forced political elites to renegotiate fundamental regime structures via the process of constitutional reform. In the five successful cases, changes in the political opportunity structure occurred that favored indigenous autonomy claimants. These changes were the opening of access to decision-making spheres and the emergence of an influential ally. Donna Lee Van Cott is assistant professor of political science at the University of Tennessee, Knoxville. She is author ofThe Friendly Liquidation of the Past: The Politics of Diversity in Latin America and editor ofIndigenous Peoples and Democracy in Latin America.     

Women law Professors

Until recently, women were rarely found on the faculties of the nation's law schools. The few who were tended to teach at their alma maters and specialized in only a few subject areas. This article reports the extent to which women have become part of the tenure track faculties of the nation's law schools. The author finds that women have made considerable progress toward becoming tenure track law teachers. She finds, however, that women law professors continue to be academically inbred in disproportionate numbers and overrepresented in some subject areas.     

Introducing Computed Tomography Standards for Age Estimation of Modern Australian Subadults Using Postnatal Ossification Timings of Select Cranial and Cervical Sites,

Contemporary, population‐specific ossification timings of the cranium are lacking in current literature due to challenges in obtaining large repositories of documented subadult material, forcing Australian practitioners to rely on North American, arguably antiquated reference standards for age estimation. This study assessed the temporal pattern of ossification of the cranium and provides recalibrated probabilistic information for age estimation of modern Australian children. Fusion status of the occipital and frontal bones, atlas, and axis was scored using a modified two‐ to four‐tier system from cranial/cervical DICOM datasets of 585 children aged birth to 10 years. Transition analysis was applied to elucidate maximum‐likelihood estimates between consecutive fusion stages, in conjunction with Bayesian statistics to calculate credible intervals for age estimation. Results demonstrate significant sex differences in skeletal maturation (p < 0.05) and earlier timings in comparison with major literary sources, underscoring the requisite of updated standards for age estimation of modern individuals.
