Here in Moscow, in the quiet light of the table lamp, you open your soiled travel notebooks and the gray, limp page strikes your eye with a shaft of multicolored rays as if the brightest slide had been inserted in a projector: a steep mountain slope in screes of red stones; a "tanker" burns, giving off smoke; greasy, sooty clouds drift toward the village; the driver in a Panama hat, having fallen down the smoking slope, breaks pale, dotted trails through the fire. The column, which makes the road shake, rolls down toward the gorge; gun barrels jerk and roar on the open flatcar.  相似文献

Over the course of the last decade, the equipment used by news organizations to transmit text, voice, and images from locations without fixed or operational communications links has changed radically. Whereas remote real-time transmissions once required tons of satellite uplink equipment, generators, and a stable of technicians, approximately the same can be accomplished today with a laptop sized device and handheld digital camera. This sort of technological prowess was seen most recently in the 2003 war in Iraq. We hypothesize that, as a result of these technological developments, the likelihood of newsgathering from remote locations has increased. By “remote location,” we mean any place without the standard technical infrastructure (fixed satellite uplinks or high-speed terrestrial lines). Most often, remoteness of this sort is a feature of nonurban, less developed regions of the world. This hypothesis is a critical but untested presumption underlying recent debates concerning the CNN effect, event-driven news, and other aspects of the changing nature of the relationships between news media and policy. In our analysis, we find evidence of a decrease in the effects of remoteness on levels of U.S. media coverage of distant events.  相似文献

A good deal of research in recent years has revisited the relationship between immigration and violent crime. Various scholars have suggested that, contrary to the claims of the classic Chicago School, large immigrant populations might be associated with lower rather than higher rates of criminal violence. A limitation of the research in this area is that it has been based largely on cross‐sectional analyses for a restricted range of geographic areas. Using time‐series techniques and annual data for metropolitan areas over the 1994–2004 period, we assess the impact of changes in immigration on changes in violent crime rates. The findings of multivariate analyses indicate that violent crime rates tended to decrease as metropolitan areas experienced gains in their concentration of immigrants. This inverse relationship is especially robust for the offense of robbery. Overall, our results support the hypothesis that the broad reductions in violent crime during recent years are partially attributable to increases in immigration.  相似文献

In a typical year, the United States Employment Service places over 4 million persons from among 16 million applicants. This investigation of which applicants are most likely to be placed shows that placement occurs in two labor market segments, corresponding roughly to the primary and secondary labor markets described in the economic literature. The equity and efficiency implications o f devoting a substantial percentage o f Employment Service resources t o secondary labor market placements are considered. Several states currently use Employment Service data as a source of local labor market information. An argument is made that these states are misusing this data and suggestions for improvements are offered.  相似文献

Research Summary: This evaluation of a directed police patrol project utilizes a pre-post quasi-experimental design with a non-equivalent control group as well as an interrupted time series analysis. The results suggest that directed patrol had an impact on firearms crime in one of the target areas but not the other. Policy Implications: The results suggest that a specific deterrence strategy whereby the police utilize directed patrol to focus on suspicious activities and locations reduced violent gun crime. In contrast, a general deterrence strategy focused on maximizing vehicle stops did not have an apparent effect.  相似文献

Although evidence of the strong correlation between deviant behavior and exposure to deviant peers is overwhelming, researchers have yet to investigate whether a nonlinear functional form better captures this relationship than does a linear form. Researchers also have yet to examine the extent to which peer effects vary as a function of the neighborhood context. To address these issues, we use data from the Project on Human Development in Chicago Neighborhoods (PHDCN) to examine 1) the functional form of the relationship between peer violence exposure and self‐reported violent crime and 2) the extent to which the effect of exposure to violent peers on violence is ecologically structured. Estimates from logistic hierarchical models indicate that the effect of peer violence exposure on violent crime decreases at higher values of peer violence, as reflected in a nonlinear relationship (expressed in terms of log‐odds). Furthermore, exposure to violent peers increases along with neighborhood disadvantage, and the effect of peer violence exposure on violent crime is attenuated as neighborhood disadvantage increases, which is reflected in a cross‐level peer violence/disadvantage interaction.  相似文献

Surveys of citizen satisfaction with local public services have become widespread, with the results increasingly used to reorganize services, to allocate budgets, and to hold managers accountable. But evidence from a split‐ballot experiment that we conducted suggests that the order of questions in a citizen survey has important effects on reported satisfaction with specific public services as well as overall citizen satisfaction. Moreover, the correlations of specific service ratings with overall satisfaction, and thus the identification of key drivers of overall satisfaction, also turn out to be highly sensitive to question order. These findings are in line with research on priming and question order effects in the survey methodology literature, but these effects have not been carefully examined before in the context of citizen surveys and public administration research. Policy and management implications of these finding are discussed.  相似文献

In recent years, criminologists, as well as journalists, have devoted considerable attention to the potential deterrent effect of what is sometimes referred to as “proactive” policing. This policing style entails the vigorous enforcement of laws against relatively minor offenses to prevent more serious crime. The current study examines the effect of proactive policing on robbery rates for a sample of large U.S. cities using an innovative measure developed by Sampson and Cohen (1988). We replicate their cross-sectional analyses using data from 2000 to 2003, which is a period that proactive policing is likely to have become more common than that of the original study—the early 1980s. We also extend their analyses by estimating a more comprehensive regression model that incorporates additional theoretically relevant predictors. Finally, we advance previous research in this area by using panel data, The cross-sectional analyses replicate prior findings of a negative relationship between proactive policing and robbery rates. In addition, our dynamic models suggest that proactive policing is endogenous to changes in robbery rates. When this feedback between robbery and proactive policing is eliminated, we find more evidence to support our finding that proactive policing reduces robbery rates.  相似文献
