One of the enduring and yet unresolved issues concerning the Civil War is its legal nature: Was it an insurrection or an international war? During the war and since, the United States courts have repeatedly been called upon to determine the status of property which was under the control of the Confederacy and its agents during the Civil War. In the process of making such determinations, the courts have reopened questions about the war's legal status. United States v. Steinmetz is such a case.

The role of the substantia nigra pars reticulata (SNPr) and superior colliculus (SC) network in rat strains susceptible to audiogenic seizures still remain underexplored in epileptology. In a previous study from our laboratory, the GABAergic drugs bicuculline (BIC) and muscimol (MUS) were microinjected into the deep layers of either the anterior SC (aSC) or the posterior SC (pSC) in animals of the Wistar audiogenic rat (WAR) strain submitted to acoustic stimulation, in which simultaneous electroencephalographic (EEG) recording of the aSC, pSC, SNPr and striatum was performed. Only MUS microinjected into the pSC blocked audiogenic seizures. In the present study, we expanded upon these previous results using the retrograde tracer Fluorogold (FG) microinjected into the aSC and pSC in conjunction with quantitative EEG analysis (wavelet transform), in the search for mechanisms associated with the susceptibility of this inbred strain to acoustic stimulation. Our hypothesis was that the WAR strain would have different connectivity between specific subareas of the superior colliculus and the SNPr when compared with resistant Wistar animals and that these connections would lead to altered behavior of this network during audiogenic seizures. Wavelet analysis showed that the only treatment with an anticonvulsant effect was MUS microinjected into the pSC region, and this treatment induced a sustained oscillation in the theta band only in the SNPr and in the pSC. These data suggest that in WAR animals, there are at least two subcortical loops and that the one involved in audiogenic seizure susceptibility appears to be the pSC-SNPr circuit. We also found that WARs presented an increase in the number of FG + projections from the posterior SNPr to both the aSC and pSC (primarily to the pSC), with both acting as proconvulsant nuclei when compared with Wistar rats. We concluded that these two different subcortical loops within the basal ganglia are probably a consequence of the WAR genetic background. (C) 2012 Elsevier Inc. All rights reserved.

This study examines the case of Vietnam and uses the method of process tracing to explore the sources of foreign policy choice and change. Foreign policy is derived from grand strategy, which refers to the full package of a state’s domestic and foreign policies. I argue that a state’s grand strategy results from the interaction of four factors—its society’s historical experience, social motivation, international power, and political contest among domestic groups. Grand strategies emerge as a response to perceived shifts in the balance of international economic, political, and military power. However, this is not to say that international pressures and incentives are translated into foreign policy. Rather, pressures and incentives are given meaning by worldviews, which reflect a society’s historical experiences of its place in the international system at traumatic junctures of its encounter with the outside world. Strategic changes in foreign policy follow what I call the “strategic algorithm,” which incorporates four major mechanisms—balancing against threat, bandwagoning with power, learning, and survival by transformation. This case study generates hypotheses for a theory of strategic choice, a theory of foreign policy transformation, and a theory of grand strategy emergence.

Tra il 1936 e il 1943 la Spagna visse un periodo di guerra civile e scontri fra la Falange e la Chiesa. Tutto ciò non fece altro che innalzare la figura di Franco, un generale, che viene sacralizzato e che governò per quasi 40 anni
