Satellite radio posed a new question for Canadian policy-makers: How to take advantage of a transnational radio service while ensuring cultural identity was not lost within channel offerings that are predominately American. Comparing the initial licensing of satellite radio in Canada (2005) to the merger of the services (2011) and the post-merger license renewal (2012) highlights a shift in the spatial understanding of satellite radio, from being determined by a satellite’s footprint to that of what I call ‘cultural lifelines,’ the various mobile devices and services that enable one to maintain connection to cultural content. Alongside shifting spatial considerations of satellite radio, Canadian content has increasingly been packaged as a brand or genre, catering to fragmented taste preferences and individual, mobile listening practices.  相似文献

Risk perceptions are important to the policy process because they inform individuals’ preferences for government management of hazards that affect personal safety, public health, or ecological conditions. Studies of risk in the policy process have often focused on explicating the determinants of risk perceptions for highly salient, high consequence hazards (e.g., nuclear energy). We argue that it is useful to also study more routinely experienced hazards; doing so shows the relevance of risk perceptions in individuals’ daily lives. Our investigation focuses on the impact perceived risk has on citizens’ preferences over hazard management policies (as distinct from identifying risk perception determinants per se). We use a recursive structural equation model to analyze public opinion data measuring attitudes in three distinct issue domains: air pollution, crime, and hazardous waste storage and disposal. We find that citizens utilize perceived risk rationally: greater perceived risk generally produces support for more proactive government to manage potential hazards. This perceived risk–policy response relationship generally holds even though the policy options respondents were asked to consider entailed nontrivial costs to the public. The exception seems to be when individuals know less about the substantive issue domain.  相似文献

While state governments have enjoyed greater control over regulating local telephone service providers since 1984, movement toward efficiency-based policy reform (e.g., adoption of competitive markets) has proceeded slowly. We investigate this pattern by addressing how the degree of policy discretion held by state public utility commissions (PUCs) affects reform of local telephone exchange regulation. Using precise measures of both PUC discretion and state policy changes over time, we find that states with "stronger" PUCs (more policymaking authority) are significantly more likely to move toward efficiency-based policy regimes and away from traditional rate-of-return regimes. Greater PUC discretion systematically related to state adoption of efficiency-based reforms over time suggests that regulators are using updated information about policy impacts to inform their policymaking activities. Our findings contradict a common presumption that regulatory bureaucracies are simply motivated by a desire to increase their control over policymaking. Instead, state PUCs are a key source of telecommunications policy reform in the states.  相似文献
