AbstractYou did it. You successfully worked with a wireless service provider to find the ideal spot for its new wireless tower. The tower is positioned perfectly—in the heart of downtown, yet safe, hidden, completely undisruptive. The provider is happy. The community is content. It’s a win‐win. Fast forward a month. The provider is back with a new idea: To support the latest technology and to enhance its revenues, it will add not one, but four 20‐foot extensions for new antennas. The extensions would make the otherwise hidden facility visible. They would reach across and over the sidewalk and street, presenting safety risks. And the provider would also add four new equipment cabinets and an equipment shelter. Your answer is easy: Absolutely not. We can find a better solution. But this time the provider is not asking, it’s demanding. It says that because it is not proposing an initial facility but a colocation, you must approve its requests. Whether the provider is correct may turn on how the Federal Communications Commission (FCC) resolves a pending rule making. This article describes the proceeding, key issues it raises, and what the proceeding may mean to you and your community. As a planner, you can influence the proceeding by meeting with the FCC to discuss the proposed rules and by responding to industry claims that local requirements are delaying deployment. 相似文献

Aerial bombardment has been an important component of counterinsurgency practice since shortly after it became a viable military technology in the early twentieth century. Due to the nature of insurgency, bombing frequently occurs in and around settled areas, and consequently it tends to generate many civilian casualties. However, the effectiveness of bombing civilian areas as a military tactic remains disputed. Using data disaggregated to the level of the smallest population unit and measured at multiple points in time, this article examines the effect of aerial bombardment on the pattern of local control in the Vietnam War. A variety of estimation methods, including instrumental variables and genetic matching, show that bombing civilians systematically shifted control in favor of the Viet Cong insurgents. 相似文献

The transition to high school has been identified as a potentially difficult time in adolescents’ lives. Reductions in both
academic and social functioning often accompany this transition. While these effects have been documented in urban youth,
the move to high school has not been extensively studied in rural minority youth. Toward that end, the academic grades and
substance use in ninth grade of 447 (184 male and 263 female) African-American adolescents from two rural counties in a state
in the deep South were examined in relation to configurations of adaptation from sixth through eighth grade. Results indicate
that individual with consistently positive patterns across middle school had higher grades and lower rates of substance use
compared to individuals with persistent difficulties or those that transitioned to problem behavior. Many individuals who
improved in their patterns of adaptation had relatively high grades, but also rather high rates of substance use in the ninth
grade.

In this article I test two competing visions about how democracy produces responsive government. Electoral theories of democracy posit that elected governments are responsive to public demands because citizens are able to sanction bad politicians and select good ones. Participatory theories attribute responsiveness to a citizenry's ability to articulate demands and pressure government through a wider range of political action. I test hypotheses derived from these two approaches, using an original dataset that combines electoral, socioeconomic, and public-financial indicators for Mexico's 2,400 municipalities, from 1989 to 2000. The data show that electoral competition has no effect on municipal government performance. But the results are consistent with the hypothesis that nonelectoral participation causes improved performance. Thus, I suggest that the quality of municipal government in Mexico depends on an engaged citizenry and cooperation between political leaders and their constituents, rather than the threat of electoral punishment. I recommend that scholars broaden the study of government responsiveness to account for participatory strategies of political influence and critically assess the claims of those who would promote elections as a cure-all for poor democratic performance. 相似文献

Why does the influence of Congressional parties fluctuate over time? Building on prevailing answers, we develop a model, Strategic Party Government, which highlights the electoral motives of legislative parties and the strategic interaction between parties. We test this theory using the entire range of House and Senate party behavior from 1789 to 2000 and find that the strategic behavior of parties complements members' preferences as an explanation for variation in party influence. Specifically, the strongest predictors of one party's voting unity are the unity of the opposing party and the difference between the parties in the preceding year. Moreover, we find strong links between party behavior in Congress and electoral outcomes: an increase in partisan influence on legislative voting has adverse electoral costs, while winning contested votes has electoral benefits. 相似文献

Globalization critics argue that international trade spurs a race to the bottom among national environmental standards. ISO 14001 is the most widely adopted voluntary environmental regulation which encourages firms to take environmental action beyond what domestic government regulations require. Drawing on a panel study of 108 countries over seven years, we investigate conditions under which trade linkages can encourage ISO 14001 adoption, thereby countering environmental races to the bottom. We find that trade linkages encourage ISO 14001 adoption if countries' major export markets have adopted this voluntary regulation. 相似文献
