L'anno che non fu? L'anno dell'Europa e la crisi nelle relazioni transatlantiche, 1973/74

The 1970s are in the limelight of a growing historiographic attention, partly due to the recent opening of new archival resources. 1973, in particular, has a special interest in the historian’s eyes, as many are the events that happened that year: to name but a few, the Chilean coup, the October War, the ensuing oil crisis, the Vietnamese peace treaty. So it is may be not entirely surprising that not much attention has been paid to the Year of Europe, a nebulous American initiative destined to sum up to nothing practical - as Kissinger himself put it, it was destined to be the Year that never Was.1 It is my opinion, however, that its failure should not conceal its historical interest. Even though transatlantic relations have sometimes been seen as an uninterrupted history of crisis,2 in 1973 they reached what could then be considered as their unprecedented nadir. I believe that a thorough analysis of the events that during that year found the US increasingly at odds with the countries of Western Europe is worth carrying out not only to cast a new light on the dynamics of transatlantic relations but also to deepen our comprehension of the internal dynamics of the actors involved, mainly the Nixon administration and a unifying Europe. The Nixon administration had not carefully planned what the initiative actually should have amounted to, and its official announcement appears to have been one of Kissinger’s coups de theatre. Yet the Year of Europe responded to the vital priority of revitalising the relations with Western Europe, crucial ally, for too long neglected. But 1973 did not end with the solemn renewal of the Atlantic Declaration that Kissinger had sought. On the contrary, it saw, for the first time, the countries of the newly enlarged EC engaged in a real, if short-lived, solidarity on foreign policy, which highlighted the Nixon administration’s contradictions regarding European integration. Those, in addition to the numerous tensions that already strained transatlantic relations, gave birth to a downward spiral of incomprehensions and misperceptions, which the unexpected deflagration of the October war seriously worsened. However, even though the tensions did not disappear, the European front soon started to disintegrate, mainly under the strains imposed by the oil crisis. Significant changes in the leadership of the main European countries helped to get the tones back to normal. During the course of 1974-5, the substantial failure of the Euro-Arab dialogue, the Gymlich compromise, frequent and serene bilateral meetings bear witness that the worst was over.

Muslime in Ruanda – von Marginalisierung zu Integration /// Arbeitspapiere / Institut für Ethnologie und Afrikastudien ; 74

Zwischen April und Juni 1994 wurden in dem kleinen zentralafrikanischen Land Ruanda ca. 800.000 Menschen ermordet worden. Die Mehrzahl der Opfer waren Tutsi, aber auch viele Hutu verloren ihr Leben. Nahezu jede internationale und nationale Organisation versagte im Angesicht des Ausmaßes der Tragödie. Auch die in Ruanda sehr einflussreiche katholische Kirche konnte oder wollte die Massaker nicht beenden. Einzig die in der ruandischen Geschichte bis zum Genozid immer marginalisierten Muslime verweigerten in der Mehrzahl eine Teilnahme an den Massakern. Warum es zu diesem Verhalten kam, steht als Ausgangsfrage zu Beginn der Untersuchung. Im Folgenden gliedert sich die Arbeit in drei Teile – Geschichte des Islam bis 1994, Verhalten der Muslime im Völkermord von 1994 und die Veränderungen in den zehn Jahren nach dem Genozid. Die Arbeit, welche sich auf die Ergebnisse einer zweimonatigen Feldforschung und einige ältere Arbeiten zum Thema stützt, macht deutlich, dass die Geschichte der ruandischen Muslime bis 1994 durch eine kontinuierliche Marginalisierung gekennzeichnet war. Als nach dem Völkermord das außergewöhnliche Verhalten der ruandischen Muslime langsam deutlich wurde, änderte sich bei vielen Menschen und auch bei offiziellen Stellen auch die Einstellung gegenüber Muslimen.

Diagnosi e terapia dei tumori delle cavita' nasali del cane

Lo studio è stato condotto su pazienti affetti da carcinoma nasale trattati con radioterapia presso il Centro Oncologico Veterinario (Sasso Marconi, BO). Lo studio, prospettico, randomizzato e in doppio cieco, ha valutato l’efficacia del trattamento radioterapico in combinazione o meno con firocoxib, un inibitore selettivo dell’enzima ciclossigenasi 2 (COX-2). Sono stati inclusi pazienti con diagnosi istologica di carcinoma nasale sottoposti a stadiazione completa. I pazienti sono stati successivamente suddivisi in due gruppi in base alla tipologia di trattamento: radioterapia associata a firocoxib (Gruppo 1) o solo radioterapia (Gruppo 2). Dopo il trattamento, i pazienti sono stati monitorati a intervalli di 3 mesi sia clinicamente che mediante esami collaterali, al fine di valutare condizioni generali del paziente, un’eventuale tossicità dovuta alla somministrazione di firocoxib e la risposta oggettiva al trattamento. Per valutare la qualità di vita dei pazienti durante la terapia, è stato richiesto ai proprietari la compilazione mensile di un questionario. La mediana del tempo libero da progressione (PFI) è stata di 228 giorni (range 73-525) nel gruppo dei pazienti trattati con radioterapia e firocoxib e di 234 giorni (range 50-475) nei pazienti trattati solo con radioterapia. La sopravvivenza mediana (OS) nel Gruppo 1 è stata di 335 giorni (range 74-620) e di 244 giorni (range 85-505) nel Gruppo 2. Non si sono riscontrate differenze significative di PFI e OS tra i due gruppi. La presenza di metastasi ai linfonodi regionali condizionava negativamente PFI e sopravvivenza (P = 0.004). I pazienti trattati con firocoxib hanno mostrato un significativo beneficio in termini di qualità di vita rispetto ai pazienti trattati con sola radioterapia (P=0.008). La radioterapia può essere considerata un’efficace opzione terapeutica per i cani affetti da neoplasie nasali. Firocoxib non sembra migliorare significativamente i tempi di sopravvivenza, ma risulta utile al fine di garantire una migliore qualità di vita.

Lipid and lipoprotein profile in HIV-infected patients treated with lopinavir/ritonavir as a component of the first combination antiretroviral therapy

We characterized lipid and lipoprotein changes associated with a lopinavir/ritonavir-containing regimen. We enrolled previously antiretroviral-naive patients participating in the Swiss HIV Cohort Study. Fasting blood samples (baseline) were retrieved retrospectively from stored frozen plasma and posttreatment (follow-up) samples were collected prospectively at two separate visits. Lipids and lipoproteins were analyzed at a single reference laboratory. Sixty-five patients had two posttreatment lipid profile measurements and nine had only one. Most of the measured lipids and lipoprotein plasma concentrations increased on lopinavir/ritonavir-based treatment. The percentage of patients with hypertriglyceridemia (TG >150?mg/dl) increased from 28/74 (38%) at baseline to 37/65 (57%) at the second follow-up. We did not find any correlation between lopinavir plasma levels and the concentration of triglycerides. There was weak evidence of an increase in small dense LDL-apoB during the first year of treatment but not beyond 1 year (odds ratio 4.5, 90% CI 0.7 to 29 and 0.9, 90% CI 0.5 to 1.5, respectively). However, 69% of our patients still had undetectable small dense LDL-apoB levels while on treatment. LDL-cholesterol increased by a mean of 17?mg/dl (90% CI -3 to 37) during the first year of treatment, but mean values remained below the cut-off for therapeutic intervention. Despite an increase in the majority of measured lipids and lipoproteins particularly in the first year after initiation, we could not detect an obvious increase of cardiovascular risk resulting from the observed lipid changes.

Distinct lake level lowstand in Lake Prespa (SE Europe) at the time of the 74 (75) ka Toba eruption

Abstract. The 74 (75) ka Toba eruption in Sumatra, Indonesia, is considered to be one of the largest volcanic events during the Quaternary. Tephra from the Toba eruption has been found in many terrestrial and marine sedimentary deposits, and acidity peaks related to the eruption have been used to synchronize ice core records from Greenland and Antarctica. Seismic profiles and sedimentological data from Lake Prespa on the Balkan Peninsula, SE Europe, indicate a lake level lowstand at 73.6±7.7 ka based on ESR dating of shells. Tephrostratigraphy, radiocarbon dating and tuning of the total organic carbon content with the NGRIP isotope record, corroborate that the lake level lowstand was a short-term event superimposed on the general cooling trend at the end of MIS 5, most likely at the onset of the Greenland Stadial GS- 20. Acknowledging that tectonic events or karst processes could have triggered this lake level lowstand, the chronological correspondence between the lowstand and the Toba eruption is intriguing. Therefore a Toba-driven short-term shift to aridity in the Balkan region, leading to lake level changes and triggering spatial expansion events in one of the lake’s most abundant benthic species, the carino mussel Dreissena presbensis, cannot be excluded.
