Transnational knowledge networks provide organizations with information useful in addressing shared problems. Social media may enable the formation of those networks, yet their role in the process has received little attention. This article examines the structure and antecedents of two networks facilitated by the microblogging platform Twitter operating in the policy domain of emergency management. One network includes national-level government agencies responsible for disaster response and recovery operations; the other includes nongovernmental organizations in the form of Red Cross and Red Crescent national societies. We use a logistic regression quadratic assignment procedure to test hypotheses derived from related literature. While findings indicate that shared language and geographic proximity shaped network formation, both networks exhibit boundary spanning behavior in which organizations sought out information from high-profile, resource-rich organizations. Those organizations helped to connect otherwise regionally bound clusters and demonstrate the nascent potential of social media to create global transnational knowledge networks. 相似文献

We conduct an impact analysis of the Denver, Colorado, Housing Authority’s Home Ownership Program (HOP) employing quasi experimental methodologies (i.e., nearest-neighbor matching, inverse probability weighting with regression adjustment) that permit causal inferences of program impacts with substantial confidence. HOP is an unusual, enhanced variant of the Family Self-Sufficiency program that incentivizes and assists participants’ purchase of a home. We analyze whether, compared with the control group, HOP participants exhibited significantly greater earnings growth during the program, enhanced economic security, and rates of home buying. We find that participants with a high intensity of treatment showed significant improvement in all outcomes. Results are robust to model specification and insensitive to omitted variable bias typically found in the social sciences. We conclude that a well-conceived and well-executed public housing authority program aimed at building the financial, human and social assets of low-income households receiving housing assistance can yield substantial benefits to participants. 相似文献

This article estimates the impact of local housing and labor market conditions on area homelessness using the U.S. Department of Housing and Urban Development's (HUD’s) annual point-in-time counts of homelessness from 2007 to 2014. In cross-sectional models, the median rent, the share of households in rental housing, and the poverty rate have strong positive impacts on homelessness. Once area-fixed effects are included, only the median rent remains positive and significant. However, fixed-effect models find a positive relationship between poverty and homelessness in communities that maintain right-to-shelter policies, suggesting constraints in shelter bed supply may limit responses of homelessness to changes in economic conditions. 相似文献

The 2009 Lisbon Treaty institutionalised an intergovernmental constitution for managing policies traditionally a matter of national sovereignty, such as foreign and defence policies. However, important innovations were introduced in the foreign policymaking structure to limit its intergovernmental logic, in particular, with regard to the role of the High Representative (HR). It was generally assumed that those innovations would have made development of a coherent EU foreign policy possible. Yet, in one of the most significant tests for the EU’s foreign and defence policies in the post-Lisbon era, namely the Egyptian crisis (2011-14), those reforms did not work as expected. Notwithstanding the innovations, the HR’s role was diminished by the European Council’s strict control over foreign policy toward Egypt. The lack of clear policy guidelines towards the issue of democratisation in the Arab world in the 2003 European Security Strategy, although partially mitigated by the European Neighbourhood Policy and the Barcelona Process/Union for the Mediterranean, made it even more difficult for the HR to bring a European perspective into the largely intergovernmental setting. 相似文献

The hegemonic power of FIFA over countries hosting its capstone World Cup tournament is worth examining in the context of hegemony theory in International Relations literature. To understand FIFA’s hegemonic role on the global stage, it is best to place it within the context of two major shifts in the international system—power transition and diffusion. This study provides an insight into the dispute between transnational and national law in sports, which FIFA has used to strengthen its hegemony. This has empirical support as seen in four World Cup cases: previous Cups in Brazil (2014) and South Africa (2010) and the forthcoming tournaments in Russia (2018) and Qatar (2022). These cases reveal FIFA’s hegemonic power both through the overruling of national law in favour of transnational law, and by the questionable bidding processes to host the games in Qatar and the Russian Federation. In addition, this study examines whether Switzerland is capable of regulating or restricting FIFA’s hegemonic power. While removing FIFA’s legal status as a non-profit organisation seems not to be an option, the executed amendment of the Swiss anti-corruption law is a step forward. Furthermore, FIFA needs to continue its recently initiated internal reforms. 相似文献

AIM:To evaluate the Z-line visualization by the PillCamTM SB2 using three different ingestion protocols. METHODS:Ninety consecutive patients undergoing small bowel capsule endoscopy(SBCE)between January and May 2008 were included in the study. They swallowed the capsule in the standing(Group A= 30),supine(Group B=30)and right supine positions (Group C=30).Baseline patient characteristics, difficulties in capsule ingestion,esophageal transit times(ETT)and Z-line visualization were noted. RESULTS:No significa... 相似文献

Issues of centralization–decentralization and centre–periphery resource distribution are frequent administrative and political concerns which can have, upon occasion, very profound consequences for the stability of a society. An analysis of recent events in Sierra Leone demonstrates their significance. On 25 May, 1997 the country's first democratically elected government in almost 30 years was overthrown after little more than a year in office by a group of rebellious military officers. Most commentators have attributed this turn of events simply to military disgruntlement. In fact, a careful analysis demonstrates that the central government's commitment to decentralization and the strengthening of local governance exacerbated the centre–periphery conflict issues that have plagued the country since its independence and thus were the real underlying causal factors. © 1997 John Wiley & Sons, Ltd. 相似文献

We analyzed 17 Y-chromosomal STR loci in a population sample of 126 unrelated Portuguese Gypsies. Fifty three different haplotypes were found, three represented with considerable high frequencies (≥8.7%). The percentage of unique haplotypes (71.2%) was rather low as well as haplotype diversity (94.37%). In the comparison with available Portuguese population data and with those from other Gypsy and general population samples from Bulgaria, Lithuania and Spain, our sample showed significant differences in comparison with the general population data from Portugal, Spain and Bulgaria. Significant differences were observed with Bulgarian Gypsies, but not with the Spanish or Lithuanian groups. The Gypsy populations from Portugal, Spain and Bulgaria were found to be more closely related to each other than with the general population from their own countries. 相似文献
