Examining the pseudo-standard web search engine results page
Nearly every web search engine presents its results in an identical format: a ranked list of web page summaries. Each summary comprises a title; some sentence fragments usually containing words used in the query; and URL information about the page. In this study we present data from our pilot experiments with eye tracking equipment to examine how users interact with this standard list of results as presented by the Australian sensis.com.au web search service. In particular, we observe: different behaviours for navigational and informational queries; that users generally scan the list top to bottom; and that eyes rarely wander from the left of the page. We also attempt to correlate the number of bold words (query words) in a summary with the amount of time spent reading the summary. Unfortunately there is no substantial correlation, and so studies relying heavily on this assumption in the literature should be treated with caution

UN Peace operations and conflicting legitimacies
Analyses of UN peacekeeping increasingly consider legitimacy a key factor for success, conceiving of it as a resource that operations should seek and use in the pursuit of their goals. However, these analyses rarely break down legitimacy by source. Because the UN is an organization with multiple identities and duties however, different legitimacy sources—in particular output and procedural legitimacy—and the UN’s corresponding legitimation practices come into conflict in the context of peacekeeping. Drawing on a range of examples and a specific case of the UN mission in Congo, this article argues that looking at different legitimacy sources and linking them to the institutional identity of the UN is thus critical and it shows how the UN’s in contradictory legitimation practices can reduce overall legitimacy perceptions

Legitimacy in conflict: concepts, practices, challenges
The study of legitimacy in situations of conflict and peacebuilding has increased in recent years. However, current work on the topic adopts many assumptions, definitions, and understandings from classical legitimacy theory, which centers on the relationship between the nation-state and its citizens. In this introduction, we provide a detailed critical overview of current theories of legitimacy and legitimation and demonstrate why they have only limited applicability in conflict and post-conflict contexts, focusing on the three main areas that the articles included in this special issue examine: audiences for legitimacy, sources of legitimacy, and legitimation. In particular, we show how conflict and post-conflict contexts are marked by the fragmentation and personalization of power; the proliferation and fragmentation of legitimacy audiences; and ambiguity surrounding legitimation strategies
Document expansion versus query expansion for ad-hoc retrieval
In document information retrieval, the terminology given by a user may not match the terminology of a relevant document. Query expansion seeks to address this mismatch; it can significantly increase effectiveness, but is slow and resource-intensive. We investigate the use of document expansion as an alternative, in which documents are augmented with related terms extracted from the corpus during indexing, and the overheads at query time are small. We propose and explore a range of corpus-based document expansion techniques and compare them to corpus-based query expansion on TREC data. These experiments show that document expansion delivers at best limited benefts, while query expansion . including standard techniques and effcient approaches described in recent work . delivers consistent gains. We conclude that document expansion is unpromising, but it is likely that the effciency of query expansion can be further improved
Whose peace? Local ownership and UN peacebuilding
Recent years have seen an increasing emphasis on local ownership in UN peacebuilding. Advocates of local ownership assert that it boosts the legitimacy and sustainability of UN peacebuilding by helping to preserve the principles of self- determination and non-imposition of externally-conceived solutions onto post-conflict countries in an activity that can contravene them. However, while the UN perceives local ownership as enabling it to act in accordance with these principles, it also perceives local ownership to imperil the achievement of its operational goals, thus bringing its normative and operational objectives into conflict. This thesis evaluates the UN’s discourse, understandings, and operationalizations of local ownership in peacebuilding. Drawing on examples from the UN peace operation in DR Congo, it shows that despite the UN’s regular invocation of local ownership discourse, it operationalizes ownership in restrictive and selective ways that are intended to protect the achievement of operational goals but that consequently limit self-determination and increase external imposition on the host country. This gap between the rhetoric and reality of ownership suggests that the UN uses local ownership primarily as a discursive tool for legitimation, one intended to reconcile the organization’s normative and operational imperatives. However, because its actions do not match its rhetoric, the UN’s attempts to generate legitimacy through discourse appear to fall flat, particularly in the eyes of local actors. Moreover, because of contradictions in the ways that the UN operationalizes local ownership, it not only deepens the curtailment of self-determination and the degree of external imposition, it also undercuts its ability to realize the very operational goals it is trying to protect. Ultimately, because it is a contradictory and contested concept, local ownership fails to eliminate or ‘fix’ the trade-offs the UN faces in peacebuilding, suggesting that the UN must instead accept them and incorporate them into its goals and expectations.</p

Local ownership and UN peacebuilding: discourse versus operationalization
The UN asserts that local ownership boosts the legitimacy and sustainabil- ity of peacebuilding by preserving the principles of self-determination and nonimposition in an activity that can contravene them. At the same time, it also perceives local ownership to imperil the achievement of its operational goals, thus bringing its normative and operational obligations into conflict. This article evaluates the UN’s discourse and operationalization of local ownership, showing that despite the UN’s invocation of ownership dis- course, it operationalizes ownership in restrictive ways that are intended to protect the achievement of operational goals but that consequently limit self-determination and increase imposition. Moreover, because of contra- dictions in the UN’s practices of ownership, it also undercuts its ability to re- alize the very operational goals that it is trying to protect. KEYWORDS: UN peacebuilding, local ownership, discourse vs. practice

Theorizing Decision-Making in International Bureaucracies: UN Peacekeeping Operations and Responses to Norm Violations
Many international organizations (IOs) provide assistance to governments through country offices or peacekeeping operations. Sometimes, government authorities in countries receiving IO services violate norms that underpin IO’s engagement. IO officials must then choose between confrontational and conciliatory responses. These responses are located on a spectrum that ranges from a firm and public response to silence and downplaying. How do IO officials decide on their response? Based on over 200 interviews with UN peacekeeping officials, we argue that the factors that shape their decision-making are found across three categories: individual, departmental, and positional. In terms of individual characteristics, previous experience, career security, and the length of service at a particular duty station matter. Regarding departmental factors, politicization of work, professional composition, and the type of interlocutors predispose departments to be supporters or critics of authorities in recipient countries. In terms of positional considerations, the place of a post or department in the IO hierarchy, relations with other IO entities, and the distance from the field play a role. While important in its own right, decision-making by civilian UN peacekeeping officials is informative about similar processes in other IOs that employ individuals from diverse backgrounds in complex bureaucracies
