If the 20th Century was the century of physics, the 21st Century is the century of cybernetics, biology and ecology. Technological advance has both crossed new frontiers and discovered old limits. Nobel laureate Ilya Prigogine broke new ground with his understanding that nature, including its human component, seeks to establish order out of chaos by “self‐organizing,” not only according to pre‐determined laws, but through random creative choices as well that are responsible for the endless novelty and potentiality of being. The technologically‐armed purposive role of humans in the Anthropocentric Age thus takes on a new significance: “What we do today depends on our image of the future rather than the future depending on what we do today” as Prigogine puts it. “The equations of the future are written in our actions as well as in nature. Time becomes construction.” Nowhere is this truer than in the new science of genomics, which touches the soul, and in the effort to preserve the ecological balance that has enabled humanity to flourish within the narrow band of earth's livable climate. In this section we bring together leading thinkers, scientists and technologists of our age to address these issues of mankind's fate.  相似文献

Youth gangs are a major part of the urban landscape. Gang members always have been involved in collective and individual violence and, in recent years, in drug use and drug dealing. Involvement in drug dealing recently has been associated with increased violence among gangs. However, variation in organizational and social processes within gangs suggests that there also will be variation in drug-crime relationships among gang members. Analyses of the drug-crime relationships were conducted from interviews with 151 gang members in three cities. Four types of gangs were identified, and similar gang types were observed in the three cities. All gang types had high involvement in drug use, but drug dealing varied. The severity of collective gang crime was associated with the prevalence of drug use within a gang. Drug dealing occurred among gangs with both high and low involvement in violence and other crimes. Involvement in cocaine, opiates, and PCP occurred among both violent and nonviolent gangs, as well as among gangs with different involvement in drug dealing. The results suggest that the drug-crime relationship is skewed and spurious for gang members, similar to relationships among nongang inner-city adolescents. Members of violent gangs more often reported the existence of several features of social organization and cohesion in their gangs, independent of gang involvement in drug use and dealing. Similar to other urban adolescents, for gang members violence is not an inevitable consequence of involvement in drug use or dealing.  相似文献

This article draws on the policy transfer literature to examine a UK‐based initiative to promote supplier diversity and provides insights into three areas neglected in current research, namely: the dynamics of non‐governmental policy transfer; the factors that mediate policy transfer in different jurisdictions; and the integration of research and practice in small business related policy transfer. To this end, an innovative action research approach is deployed with the dual purpose of effecting practical change and advancing knowledge. This comprises two phases: first, a realist analysis of the US National Minority Supplier Development Council (NMSDC), an exemplar intermediary; and second, the implementation and concurrent realist evaluation of a supplier diversity initiative modelled on NMSDC, referred to as ‘Supplier Development East Midlands’ (SDEM). The findings provide lessons for academics and practitioners dealing with small and medium‐sized enterprise (SME) policy transfer in general and supplier diversity intermediaries in particular.  相似文献
