The article deals with Czechoslovak dissident culture after 1968, in particular with the movement Charter 77 and its legacy after 1989, focusing on the concept of paralelní polis (parallel polis) introduced by Václav Benda and widely discussed among dissidents: the idea of creating new and independent cultural, economic, and media structures parallel to the official structures. The study considers the paralelní polis as an instrument through which the (post-)‘68-movements led by intellectuals, artists, and theorists sought the emancipation and diversification of civil society in both capitalist and socialist countries. With the collapse of the socialist world after 1989, the history of the paralelní polis reveals that the ‘68 idea of civil society was ambivalent, while Charter 77 proved to be a heterogeneous movement. Many ex-Chartists came to believe that capitalism could better enable the existence of a civil society than socialism, while others did not accept this view. Moreover, even among the supporters of capitalism there was no unity (some were close to neoliberalism, others were critical of it). In contrast to the 1960s and 1970s, there was no dialogue between these different positions within civil society, but rather radicalization and exclusivity. The radical left, anarcho-capitalism, and Christian fundamentalism developed their particular and mutually exclusive narratives about the legacy of paralelní polis.

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Map Resolution

X-rays are emitted from a relatively large volume in bulk samples, limiting the smallest features which are visible in X-ray maps. Beam spreading also hampers attempts to make geometric measurements of features based on their boundaries in X-ray maps. This has prompted recent interest in using low voltages, and consequently mapping L or M lines, in order to minimize the blurring of the maps.An alternative strategy draws on the extensive work in image restoration (deblurring) developed in space science and astronomy since the 1960s. A recent example is the restoration of images from the Hubble Space Telescope prior to its new optics. Extensive literature exists on the theory of image restoration. The simplest case and its correspondence with X-ray mapping parameters is shown in Figures 1 and 2.Using pixels much smaller than the X-ray volume, a small object of differing composition from the matrix generates a broad, low response. This shape corresponds to the point spread function (PSF). The observed X-ray map can be modeled as an “ideal” map, with an X-ray volume of zero, convolved with the PSF. Figure 2a shows the 1-dimensional case of a line profile across a thin layer. Figure 2b shows an idealized noise-free profile which is then convolved with the PSF to give the blurred profile of Figure 2c.
