Japanese cedar rings sampled from Aomori Prefecture, Japan, were measured to obtain tree-ring radiocarbon data covering a period of the latter half of the 20th century in the northernmost area of Honshu (mainland Japan), to obtain records of variation in atmospheric 14C concentration caused by past atmospheric nuclear testing, and to study any possible local effects. This work, carried out on a partial disk, was also intended to provide a reference for data obtained by core sampling of live, standing Japanese black pines as a part of marine environmental studies.

Europa Środkowa stanowi zarówno ideę wspólnoty kulturowej, przestrzeń geopo­lityczną i geokulturową, jak i pewną koncepcję polityczną. W ostatnich kilku dekadach jesteśmy świadkami przejścia czy raczej interferencji od idei literacko-kawiarnianej ku politycznym formom instytucjonalizacji Europy Środkowej. Celem niniejszego artykułu jest ukazanie owej drogi oraz klu­czowych dylematów stojących przed architektami politycznej Europy Środkowej. W artykule omó­wiono zatem dyskurs środkowoeuropejski w latach 70. i 80. XX w., a następnie poszczególne uwa­runkowania i etapy politycznej instytucjonalizacji Europy Środkowej z naciskiem na okres po 2004 r.Central Europe — from the café literary idea to political concepts Central Europe is both an idea of a cultural community, a geopolitical and geo­cultural space, as well as a concrete political concept. In the last decades, we are the witnesses of tran­sition or rather an interference from the literary-cafeteria idea towards the political forms of institutionalization of Central Europe. The aim of this article is to show this way and key dilemmas facing the political architects of Central Europe. The article discusses the Central European discourse in the 70s and 80s of the 20th century, and then the various conditions and stages of the political institu­tionalization of Central Europe with an emphasis on the period after 2004.

The Impact

The victory of Dogali (1887) represents the first successful resistance to European colonialism in Northeast Africa, and as such its historical significance has been immense. For some obscure reason, however, it was neglected in Ethiopian historiography until the last quarter of the 20th century when it was popularized for academic and political purposes. Its impact in history was twofold: on the international level, it cracked the Triple Alliance which ʿAdwa, the historical culmination of Dogali, subsequently rendered ineffective for good. On the national or regional level, Dogali initiated a campaign for liberty and sovereignty which was to last for decades and in which ʿAdwa and Maycäw were to stand as landmarks. These landmarks were nonetheless fought deep in the heart of the country, and in this respect Dogali, which took place way out of the effective control of the Empire, is no doubt exemplary.

This paper aims to describe and explain the beginning and evolution of cost accounting in Spain through the examination of accounting texts. In this evolution, three periods are distinguished: the late 19th century, the first half of the 20th century, and 1951–1978. In 1978, the official standardization of Spanish cost accounting occurred. Cost accounting first appeared in Spanish texts at the start of the 20th century. However, in 19th century accounting treatises can be found references to some aspects of cost accounting to which the paper refers. The traditional orientation of authors in the second period clearly reflects a monistic recording pattern, i.e., that cost accounting in combination with general accounting forms a homogeneous whole, with full-cost allocation on the basis of historical costs. The small differences found among these authors relate to a large extent to the fixed-costs allocation. This period corresponds to the introduction into Spain of the Central European school of accounting thought represented by Pedersen, Schmalenbach, Palle Hansen, and, above all, by Schneider. This influence intensified from 1951 onward. In the second half of the 20th century, German thought shared influence with American thought represented in the works of Kester, Horngren, Lang, Lawrence, Neuner, etc. The French Accounting Plan (General Chart of Accounts), published in 1957, also had an obvious influence on Spanish accounting scholars of this time. This influence is clearly shown in the Spanish standardization of cost accounting published in 1978 as part of the first Plan General de Contabilidad (General Accounting Plan) passed in 1973.

14C dating results derived from an absolutely-dated 471-year tree-ring sequence from central European oak show a trend towards somewhat older dates than those for bristleconepine tree rings of the same age, but similar to those for Egyptian historical samples. Differences visible between these trend lines are not relevant considering the standard errors proposed by Clark (1975).

The objective of this paper is to provide an overview of the current status of rabies in Europe, with special emphasis on Croatia and Southeast and East Europe. Due to the systematic implementation of a rabies eradication program by oral vaccination of wild animals, by the end of the 20th century, most West and Central European countries were rabies-free. The EU goal was to eradicate rabies in wildlife and domestic animals by 2020. No matter how achievable the goal seemed to be, the disease is still present in the eastern part of the EU, as was notified in 2020 by two member states—Poland and Romania. Croatia has been rabies-free for the last seven years but given that it borders a non-EU country in which a case of rabies was confirmed in 2020, it will continue to contribute to the maintenance of the rabies-free region. A rabies-free EU can only be achieved by continuous oral vaccination, coordination and a regional approach. The prevention of reintroductions from bordering countries in which rabies has not been eradicated yet, and the support for the eradication efforts made by these countries, are goals still pending.
