Walled in: ordinary East Germans' responses to 13 August 1961

The building of the Berlin Wall on 13 August 1961 had repercussions not only on the international scene, but also for the power relationship between state and society in the German Democratic Republic. This article considers the short-, medium- and long-term reactions of the East German population to the border closure from a personal and political perspective, examining key groups such as educated elites, workers, and young people. The closed society elicited a new deference in the short term, but the author argues for considerable continuities of low-level disruptive behavior before and after 13 August. In the longer term, there was a generation born behind the Wall which by simple habituation rather than a conscious decision was forced to accept the new contours of the geopolitical landscape created by the Wall.

Vertical toleration as a liberal ideal

This paper argues that the direct, vertical toleration of certain types of citizen by the Rawlsian liberal state is appropriate and required in circumstances in which these types of citizen pose a threat to the stability of the state. By countering the claim that vertical toleration is redundant given a commitment to the Rawlsian version of the liberal democratic ideal, and by articulating a version of that ideal that shows this claim to be false, the paper reaffirms the centrality of vertical toleration in the Rawlsian liberal account of state-citizen relations.

Should retributivists prefer pre-punishment?

Some philosophers believe that we can, in theory, justifiably pre-punish people – that is, punish them for a crime before they have committed that crime. In particular, it has been claimed that retributivists ought (in principle) to accept pre-punishment. The question of whether pre-punishment can be justified has sparked an interesting and growing philosophical debate. In this paper I look at a slightly different question: whether retributivists who accept that pre-punishment can be justified should prefer (ordinary) post-punishment or pre-punishment, or see them (in principle) as on a par. The answer is complex: asking this question brings to light unrecognised distinctions within both retributivism and pre-punishment, giving us four different answers to the question, depending on what kind of retributivism and what kind of pre-punishment are combined. Surprisingly, given that it is usually presented as a second best, to be pursued only when post-punishment is unavailable, some combinations will find pre-punishment preferable.

The medieval climate anomaly and Byzantium: a review of the evidence on climatic fluctuations, economic performance and societal change

At the beginning of the Medieval Climate Anomaly, in the ninth and tenth century, the medieval eastern Roman empire, more usually known as Byzantium, was recovering from its early medieval crisis and experiencing favourable climatic conditions for the agricultural and demographic growth. Although in the Balkans and Anatolia such favourable climate conditions were prevalent during the eleventh century, parts of the imperial territories were facing significant challenges as a result of external political/military pressure. The apogee of medieval Byzantine socio-economic development, around AD 1150, coincides with a period of adverse climatic conditions for its economy, so it becomes obvious that the winter dryness and high climate variability at this time did not hinder Byzantine society and economy from achieving that level of expansion. Soon after this peak, towards the end of the twelfth century, the populations of the Byzantine world were experiencing unusual climatic conditions with marked dryness and cooler phases. The weakened Byzantine socio-political system must have contributed to the events leading to the fall of Constantinople in AD 1204 and the sack of the city. The final collapse of the Byzantine political control over western Anatolia took place half century later, thus contemporaneous with the strong cooling effect after a tropical volcanic eruption in AD 1257. We suggest that, regardless of a range of other influential factors, climate change was also an important contributing factor to the socio-economic changes that took place in Byzantium during the Medieval Climate Anomaly. Crucially, therefore, while the relatively sophisticated and complex Byzantine society was certainly influenced by climatic conditions, and while it nevertheless displayed a significant degree of resilience, external pressures as well as tensions within the Byzantine society more broadly contributed to an increasing vulnerability in respect of climate impacts. Our interdisciplinary analysis is based on all available sources of information on the climate and society of Byzantium, that is textual (documentary), archaeological, environmental, climate and climate model-based evidence about the nature and extent of climate variability in the eastern Mediterranean. The key challenge was, therefore, to assess the relative influence to be ascribed to climate variability and change on the one hand, and on the other to the anthropogenic factors in the evolution of Byzantine state and society (such as invasions, changes in international or regional market demand and patterns of production and consumption, etc.). The focus of this interdisciplinary

Magnetic Susceptibility Measurements at Ultra-low Temperatures

We report the design and operation of a device for ac magnetic susceptibility measurements that can operate down to 1 mK. The device, a modification of the standard mutual inductance bridge, is designed with detailed consideration of the thermalization and optimization of each element. First, in order to reduce local heating, the primary coil is made with superconducting wire. Second, a low-temperature transformer which is thermally anchored to the mixing chamber of a dilution refrigerator, is used to match the output of the secondary coil to a high-sensitivity bridge detector. The careful thermal anchoring of the secondary coil and the matching transformer is required to reduce the overall noise temperature and maximize sensitivity. The sample is immersed in liquid (3)He to minimize the Kapitza thermal resistance. The magnetic susceptibility of several magnetic compounds, such as the well-known spin gap compound NiCl(2)-4SC(NH(2))(2) and other powdered samples, have been successfully measured to temperatures well below 10 mK.

Non-Fermi-liquid behavior in UCu(4+x)Al(8-x) compounds

We report on experimental studies of the Kondo physics and the development of non-Fermi-liquid scaling in UCu(4+x)Al(8-x) family. We studied 7 different compounds with compositions between x = 0 and 2. We measured electrical transport (down to 65 mK) and thermoelectric power (down to 1.8 K) as a function of temperature, hydrostatic pressure, and/or magnetic field. Compounds with Cu content below x = 1.25 exhibit long-range antiferromagnetic order at low temperatures. Magnetic order is suppressed with increasing Cu content and our data indicate a possible quantum critical point at x(cr) approximate to 1.15. For compounds with higher Cu content, non-Fermi-liquid behavior is observed. Non-Fermi-liquid scaling is inferred from electrical resistivity results for the x = 1.25 and 1.5 compounds. For compounds with even higher Cu content, a sharp kink occurs in the resistivity data at low temperatures, and this may be indicative of another quantum critical point that occurs at higher Cu compositions. For the magnetically ordered compounds, hydrostatic pressure is found to increase the Neel temperature, which can be understood in terms of the Kondo physics. For the non-magnetic compounds, application of a magnetic field promotes a tendency toward Fermi-liquid behavior. Thermoelectric power was analyzed using a two-band Lorentzian model, and the results indicate one fairly narrow band (10 meV and below) and a second broad band (around hundred meV). The results imply that there are two relevant energy scales that need to be considered for the physics in this family of compounds. (C) 2011 Elsevier B.V. All rights reserved.

O estado necessário para a democracia possível na América latina

Uma democracia consolidada pressupõe um estado capaz, e para ambos é necessária uma nação forte e uma sociedade civil ativa. Diversas democracias na América Latina não alcançaram tais requisitos porque não completaram suas respectivas revoluções capitalistas, e o excedente econômico continua dependendo do controle direto do estado. Este fato demonstra que a qualidade das democracias varia de país para país, e prevê que as democracias possíveis nos países mais pobres serão necessariamente democracias limitadas. Desde que a democracia tornou-se uma justificativa para pressões e intervenções externas, é um erro incluir no conceito de democracia mais do que as necessidades mínimas, práticas. Por outro lado, para melhorar a democracia é necessário aumentar a capacidade do estado não apenas para assegurar o respeito às leis, mas também para promover o desenvolvimento econômico e social.

Nação, sociedade civil, estado e estado-nação: uma perspectiva histórica

Nação e sociedade civil são formas de sociedades politicamente organizadas, o estado, a instituição central, e o estado-nação a unidade político-territorial que se formaram a partir da Revolução Capitalista. Cada país de um estado-nação é constituído de uma nação ou uma sociedade civil, um estado e um território. Cada estado é a expressão de sua respectiva forma de sociedade politicamente organizada, mas a relação entre estado e sociedade é explicitamente dialética, uma vez que cada sociedade nacional cria seu estado para que este a regule. Considerando-se que essas definições são históricas, as formas de sociedade e, correspondentemente, as formas de estado se transformam de acordo com a história. Este trabalho apresenta de forma sumária estas formas históricas.
