A case of a four-month-old male infant is described who was found unresponsive at home and brought to the emergency room. He lived for four days. During his hospital admission he was diagnosed by radiography with a fracture of the third lumbar vertebra that was presumed abusive in nature. Autopsy examination failed to confirm a fracture. However, a defect in the development of the vertebral bodies was discovered. He was diagnosed with possible failure of the notochord to regress, a condition with no significant sequelae. The cause of death was certified as sudden infant death syndrome after full investigation, and all autopsy studies were negative. 相似文献

Der Beitrag befasst sich mit den exogenen Bestimmungsfaktoren der Koordination raumwirksamer Politiken anhand der vier Agglomerationen von Basel, Bern, Lausanne und Genf. Ein Vergleich von entsprechenden Outcomes zeigt markante Unterschiede zwischen den vier Städten. Nach einer kurzen Kritik der Binnenorientierung gängiger Governance-Ansätze werden die drei exogenen Erklärungsansätze der politischen Geographie, des Institutionalismus und der politischen Kultur in vier Thesen beschrieben. Deren Exploration weist die Wichtigkeit von Kontextvariablen bei der Untersuchung von Ressourcen-Regimen aus. So ist eine Abhängigkeit der inhaltlichen Koordination von soziokulturellen, geographischen und historischen Faktoren auszumachen. Dagegen ist der Zusammenhang mit der Einschätzung der institutionalisierten Koordination nicht eindeutig, was die Vermutung nahelegt, dass im Falle der prozeduralen Koordination die endogenen Faktoren stärkere Erklärungskraft besitzen und die Regime Analysis mithin das geeignetere Mittel zu ihrer Untersuchung darstellt. 相似文献

The riskiness of state employee pension plan portfolios varies across states. We investigate whether this variation is related to how public employees and taxpayers share actuarial surpluses of pension accounts. We focus on two determinants of a plan’s asset mix: the relative influence of public employees to taxpayers; and whether a surplus-sharing contract is specified. Our theoretical model demonstrates that the effect of public employee influence on the asset mix is ambiguous. Our empirical results corroborate this complex theoretical result. In our theoretical and empirical analyses, if a surplus sharing rule is specified, plans adopt a more aggressive investment allocation. 相似文献

States closely regulate the policies of their local units of government through the imposition of direct order mandates. The general literature on state as well as federal mandate activities suggests that such regulations seriously constrain local autonomy and add to local financial burdens. A case study of the application of California's planning mandates in a sample of small nonmetropolitan cities suggests that major programmatic mandates are not always restrictive; mandates can be beneficial by empowering local officials. 相似文献

Experiences with racism are a common occurrence for African American youth and may result in negative self perceptions relevant
for the experience of depressive symptoms. This study examined the longitudinal association between perceptions of racism
and depressive symptoms, and whether perceived academic or social control mediated this association, in a community epidemiologically-defined
sample of urban African American adolescents (N = 500; 46.4% female). Structural equation modeling revealed that experiences with racism were associated with low perceived
academic control, which in turn was associated with increased depressive symptoms. Findings suggest that experiences with
racism can have long lasting effects for African American youth’s depressive symptoms, and highlight the detrimental effects
of experiences with racism for perceptions of control in the academic domain. Implications for intervention are discussed.

Since 1960, it has been demonstrated by various analytical procedures that high concentrations of arsenic were present in Napoleon's hair. Various authors, indicating that the detected arsenic levels are a consequence of external contamination, have challenged the results of these examinations. We have tested two strands of hair, referenced as Noverraz and Grand Maréchal Bertrand. Samples were incubated 6 h in water at 90 °C, and arsenic speciation was carried out by HPLC–ICP/MS. The residue was injected on a cation-exchange PRP-X200 column that allows the detection of arsenobetaine and on an anion-exchange PRP-X100 column to test for the mineral forms. In these conditions, the inorganic species As(III), As(V) and their metabolites (DMA and MMA) were separated. Analysis of hair samples highlighted massive amounts of total arsenic (42.1 and 37.4 ng/mg). Arsenical species found in the two samples of analyzed hair are distributed in the following: As(III) 31.1 and 44.7%; As(V) 66.3 and 53.2%; DMA 0.42 and 0.15%. Traces of MMA were detected, and 2% of the species could not be identified. These results prove that more than 97% of the arsenic found in the hair of Napoleon is in inorganic form, which is consistent with a chronic intoxication to arsenic. 相似文献

The high social cost of domestic violence has caught the attention of lawmakers and criminal justice agency administrators
across the country. As public awareness and concern over the incidence of domestic violence has risen, domestic violence legislation
has focused on, among other things, the law enforcement response to domestic violence. The purpose of this study is to examine
Florida law enforcement agency response to domestic violence by analyzing agency standard operating procedures (SOPs) across
measures identified in the Florida Model Policy for Domestic Violence. Utilizing content analysis, the authors identify agency
policy mandates including the number of officers responding to the scene, the use of specialized units, availability of victim
advocates, and procedures for investigation. 相似文献
