The technological gatekeeper: Evidence in three industries

Previous studies have developed the concept of the “technological gatekeeper” as one who is integral in the diffusion of scientific and technical information from the environment into the R&D firm. Gatekeepers have been found in firms operating in environments with rapidly changing technology. Using data from six firms in three industries, the present study found the gatekeeper phenomenon extends to firms with less rapidly changing environments. Thus, the gatekeeper construct becomes important to any firm with a R&D mission. Additionally, many of the sociometric and demographic characteristics of gatekeepers were validated in new research settings.     

Changing biases in the operation of the UK's electoral system, 1950–97

The biased outcomes of recent British general elections, whereby the two main parties (Conservative and Labour) would have achieved different percentages of the seats in the House of Commons for the same percentages of the votes cast, are explored, using a method of bias decomposition developed by a New Zealand political scientist. Overall, the situation changed markedly between 1950 and 1997: the biases in the system strongly favoured the Conservatives in the 1950s and early 1960s, but Labour in 1992 and 1997. Examination of the seven components of the bias measure shows that most of these moved in Labour's favour over the 50-year period, with a major shift between 1992 and 1997 because of the greater geographical efficiency of the Labour party's vote at the latter date: reasons for this are suggested.     

Small enterprise opportunities in municipal solid waste management

Most developing countries are rapidly urbanizing, with growing urban populations fueling demand for more and better urban services which many cities simply cannot provide given the current financial constraints. With the public sector unable to service the needs of expanding cities, small businesses are moving in to fill the vacuum. Such fledgling private sector initiatives have often prevented problems from becoming crises, while also demonstrating that private sector enterprises have an important role to play in meeting the demand for municipal services. Waste collection and processing is an area which could benefit from private sector involvement and greater public-private coordination. The authors examine the progress to date of an action-research initiative led by the Collaborative Group on Municipal Solid Waste Management in Low-income Countries which is developing best practice guidelines for expanding the involvement of micro- and small enterprises in municipal solid waste management.     

Assessing Correlates of Onset, Escalation, Deescalation, and Desistance of Delinquent Behavior

This article evaluates the utility of social development model constructs toassess the correlates of onset, escalation, deescalation, and desistance ofdelinquent behavior, from age 12 to age 15, using a dynamic classificationapproach. Dynamic classification places individuals into categories basedon changes in levels of delinquent behavior over time. These analyses assessthe extent to which specific constructs are associated with changes in thedelinquency status of individuals. Constructs of the social developmentmodel (SDM), including opportunities for conventional involvement, skillsfor conventional involvement, rewards for conventional involvement,proactive family management, bonding to conventional society, opportunitiesfor antisocial involvement, antisocial interactions, perceived rewards forantisocial involvement, and norms against drug use, were significantlyassociated with change in delinquent behavior over time. Many of theconstructs were particularly salient in distinguishing between youths whoremained involved in delinquency and youths who deescalated or desisted fromdelinquent behavior during this period. Implications for preventiveinterventions and criminological theory are discussed.
