The press is essential for creating an informed citizenry, but its existence depends on attracting and maintaining an audience. It is unclear whether supply-side effects—including those dictated by the owners of the media—influence how the media cover politics, yet this question is essential given their abilities to set the agenda and frame issues that are covered. We examine how ownership influences media behavior by investigating the impact of Rupert Murdoch’s purchase of the Wall Street Journal (WSJ) in August 2007. We collect data on every front-page story and editorial for 27 months, and we compare the difference in political coverage between the New York Times (NYT) and WSJ using a difference-in-differences design. We show that the amount of political content in the opinion pages of the two papers were unchanged by the sale, but the WSJ’s front-page coverage of politics increased markedly relative to the NYT. Similar patterns emerge when comparing the WSJ’s content to USA Today and the Washington Post. Our finding highlights potential limits to journalists’ ability to fulfill their supposed watchdog role in democracies without interference from owners in the boardroom.  相似文献

This article asks why, in contrast to other historic territories with a regional language, such as Catalonia and the Basque Country, nationalist parties in the Autonomous Community of Galicia receive less electoral support. Going beyond prior explanations of this counterintuitive political outcome, which were mainly based on economic, sociological, and institutional factors, this piece of research sheds light on the strategies of political parties. It examines not only nationalist forces but statewide ones that successfully compete in Galicia. Our analysis is focused on the Bloque Nacionalista Galego (BNG) because this is the only nationalist force that has consistently achieved representation within the regional Parliament. Along with BNG's translation into party positions in both the left-right and center-periphery dimensions, the article's main contribution is its updating of the BNG's three framing strategies: the nationalism/“Spanishism” (1982–1993), the “common project” discourse (1993–2005), and the sovereigntist one (2005 onward). Shifts in public opinion regarding the territorial model and other attitudes toward self-government are also examined.  相似文献

Policymakers have actively pursued urban renewal and dispersal programs to deconcentrate poverty in urban neighborhoods. Relocation strategies lead to new housing opportunities and may encourage employment opportunities for relocated residents if resourceful contacts and job information become more easily available after the move. This study provides an innovative evaluation of the early impacts of involuntary relocation programs in the Netherlands on the housing careers, earnings and employment rates of forced relocatees. It establishes a quasi-experimental design by employing unique longitudinal individual-level population registry data from Statistics Netherlands: forced relocatees are tracked and matched to a control group consisting of similar residents that were not forced to move. A difference-in-difference design shows that forced relocatees are living in less deprived neighborhoods after the move. However, we find no conclusive evidence that this upgrade in housing leads to more socioeconomic opportunities for the forced relocatees.  相似文献

Child abuse and neglect are complex and polarizing issues in many low and middle income countries. We explore them through a situation analysis of child rights and protection in Uganda. A qualitative study, incorporating 10 focus group discussions (FGDs; N = 113) and 20 individual interviews was undertaken in Kampala, Uganda. Emerging themes were grouped into family and community-level factors; legal framework, structure and continuum of services, and human and financial resources. Violation of child rights was characterized by physical, emotional, and sexual abuse and exploitation; child neglect, homelessness, and child labor; dysfunctional families and abject poverty; and poor accommodation conditions; school drop-out due to economic hardship; early pregnancy, and social exclusion. Legal and regulatory factors included traditional harmful practices (including child sacrifice and witchcraft practices); forced marriage; and the perceived lack of the government's commitment to child protection. Without a strong legislation that protects children against abuse, promotes confidential reporting systems, and tackles domestic violence, children will still remain prone to various forms of abuses and exploitation.  相似文献

Abstract

This article explores collaborative activities across organizational and sectoral boundaries. Interorganizational collaborations are an increasingly common setup to address societal needs; however, current research lacks insights into such collaborations and their outcomes. This study contributes to the existing literature by assessing empirically perceptions of interorganizational collaboration outcomes, considering different dimensions that should be measured when planning and performing tasks of social interest. The article is set in the context of disaster relief, where actors from different humanitarian relief organizations within the public and nonprofit sector engage in collaborative activities. I describe how interorganizational collaborations create outcomes for (1) the partnership structure that is established, (2) single organizational members involved in the collaborative activity, and (3) the community targeted by the interorganizational operation.  相似文献

Traditional American Government textbooks are expensive and often unpopular with students. New technologies and Open Educational Resources (OERs) open up the potential for change, but questions of quality are ever present: can OERs really help students learn better, or are they just cheaper? I developed an OER based on original sources and compared student learning outcomes with the OER section to those in a free digital textbook section. While the OER I created did not work as well as I had hoped, I nonetheless developed a redesign of my course and my approach to teaching, which is the true benefit of adopting OERs.  相似文献

Among local governments, inter-municipal cooperation is the growing reform; but the literature is silent regarding the determinants of longer-term shared service agreements. We conducted a survey of all local governments in New York State in 2013 to assess the level of sharing across 29 public services. The duration of shared service agreements varies from 1 to 80 years. What explains this difference? Our hierarchical linear model shows that service sharing agreements fall along a cooperation continuum, where cost savings are a determinant of shorter agreements, while the public values of service quality and cross-jurisdictional coordination explain longer-term agreements. We also find that positive past experience with sharing partners increases the duration of sharing agreements. Our analysis lays the foundation for new theories of shared services that build directly from the benefits of improved regional coordination, inter-municipal reciprocity and service quality, not from theories based solely on competition and costs.  相似文献

State sponsorship of terrorism, where a government deliberately provides resources and material support to a terrorist organization, is common in the international system. Sponsorship can provide significant strategic and political benefits for a state, but there are inherent international and domestic risks associated with delegating foreign policy to these actors. Using principal–agent analysis, I develop a model that evaluates the impact of potential costs and benefits on a state’s decision to sponsor terrorism. I test my model by using a novel dataset on sponsorship behaviors that ranges from 1970 to 2008. The results of my analysis support the validity of the principal–agent model in explaining sponsorship, as states will be more likely to engage in sponsorship when the strategic benefits of weakening the targeted state are high and the risks of international reputation loss and domestic dissatisfaction are low.  相似文献
