Different Parts

A few years ago, David Bayley and Clifford Shearing (1996) argued that at the end of the 20th century we were witnessing a ‘watershed’ in policing, when transformations were occurring in the practices and sponsorship of policing on a scale unprecedented since the developments that heralded the creation of the ‘New Police’ in the 19th century. In this special issue of the journal, we and our fellow contributors turn our attention to a somewhat neglected aspect of this ‘quiet revolution’ in policing (Stenning & Shearing, 1980), namely the nature of the opportunities for, and challenges posed by, the reform of policing in different parts of the world at the beginning of the 21st century. Our attention in this issue is particularly focused on the opportunities, drivers and challenges in reforming public (state-sponsored) police institutions.

Abstract The present issue of Chinese Semiotic Studies is published in memory of Thomas A. Sebeok. Sebeok was not only a master semiotician, but more importantly a grand artist in semiotics. As one of the most important contemporary figures in semiotics, linguistics, ethnology, and cultural studies, Sebeok made profound contributions to the progress of global semiotics through his distinguished theoretical achievements and promotional activities. His works have proven to be so relevant that they continue to exert a determinative influence and provide directions for the development of semiotics and its many subdivisions, especially biosemiotics, beyond the 20th century. Now, 21 years into the present century, during which semiotic studies around the world have made remarkable progress, it is about time to highlight some specific ways in which his contributions will continue to shape and guide semiotic studies, demonstrating the relevance of these contributions to the 21st century challenges. To this end, this special issue presents some up-to-date and informed studies that explore Sebeok’s contributions to semiotics and their vital implications for fundamental problems relevant to humanity as a semiotic animal in the present day and in the rest of this century and beyond.

The Silk Road

The Silk Road as an image is a relatively new one for Afghanistan. It appeals to both the pre-Islamic and the perceived Islamic past, thus offering an Islamic balance to previous identities linked to Bamiyan or to the Kushans. It also appeals to a broader and more international image, one that has been taken up by many other countries. This paper traces the rise of the image of the Silk Road and its use as a metaphor for ancient trade to encompass all contacts throughout Eurasia, prehistoric, ancient and modern, but also how the image has been adopted and expanded into many other areas: politics, tourism and academia. It is argued here that the origin and popularity of the term lies in late 20th century (and increasingly 21st century) politics rather than any reality of ancient trade. Its consequent validity as a metaphor in academic discussion is questioned

Space Activities

During the second half of the 20th century and the beginning of the 21st century, space hazards multiplied, the most urgent of which is space debris. Professionals working in space are exposed to this hazard daily and are aware of it as a problem. Furthermore, increasing attention is being paid to the unpredictable behavior of the Sun, which produces the so-called space weather. The asteroid-comet hazard is considered as potentially having the most catastrophic consequences. No manifestations of biological hazard have yet been observed, although as space activities develop, it is becoming increasingly important. The appropriate time scale for astrophysical hazards is many millions of years, so from a practical perspective, they have no importance. This article briefly describes the main types of space hazards. The author analyzes the results of research and practical work in the field, both worldwide and specifically in Russia. Comparative analysis leads to the clear conclusion that a national program must be developed for the study of space hazards and to respond to space threats. This article is based on a report made by the author at the meeting of the Presidium of the Russian Academy of Sciences (RAS) on January 15, 2019.
