Abstract
Prior studies have shown that terminology support can improve health information retrieval but have not taken into account the characteristics of the user performing the search. In this chapter, the impact of translating queries’ terms between lay and medico-scientific terminology, in users with different levels of health literacy and topic familiarity, is evaluated. Findings demonstrate that medico-scientific queries demand more from the users and are mostly aimed at health professionals. In addition, these queries retrieve documents that are less readable and less well understood by users. Despite this, medico-scientific queries are associated with higher precision in the top-10 retrieved documents results and tend slightly to generate knowledge with less incorrect contents, the researchers concluded that search engines should provide query suggestions with medico-scientific terminology, whenever the user is able to digest it, that is, in users above the lowest levels of health literacy and topic familiarity. On the other hand, retrieval systems should provide lay alternative queries in users with inadequate health literacy or in those unfamiliar with a topic. In fact, the quantity of incorrect contents in the knowledge that emerges from a medico-scientific session tends to decrease with topic familiarity and health literacy. In terms of topic familiarity, the opposite happens with Graded Average Precision. Moreover, users most familiar with a topic tend to have higher motivational relevance with medico-scientific queries than with lay queries. This work is the first to consider user context features while studying the impact of a query processing technique in several aspects of the retrieval process, including the medical accuracy of the acquired knowledge.

Abstract
Purpose
This chapter argues that, though the field of library and information science has made some progress in advancing diversity and inclusion, race still needs to be acknowledged as a barrier and its collateral damage needs to be spoken in order to ensure equity in our practice, research, and/or service. Core to the argument is that race as a univariate measure, equated with phenotype, is problematic and simplistic. This chapter instead makes a case for race as multidimensional. Although race figures in how one is perceived, this lens diminishes the agency of people of color to define themselves through their own worldview, experiences, and actions.
Methodology/approach
The chapter is a collection of interwoven first-person essays that reveal what people see, perceive, and mask, with the intention to continue to push an authentic conversation on race in the field. Contributors include librarians, educators, and scholars, who represent distinct dimensions of the race spectrum, question such categorization, and do not necessarily neatly fit into a racial category. They explore how they view race in the library and information field, the extent to which they feel included or not, and how they have attempted and continue to shape the field through their practice, research, and/or service.
Findings
As individuals, each contributor speaks in their own voice, and as a collective, the authors move the race dialogue forward by speaking about dimensions of race from their own experiences, representing individual stories, and allowing their intersections to be revealed.

Abstract
Regionalism implying some form of city-region or metropolitan-level planning and governance has long been promoted for multiple reasons albeit with varied success. Experiencing a resurgence in 1990s, regional coordination and cooperation has proven effective in pursuing economic development and bolstering competitiveness. Unfortunately, other voices, such as those promoting regional scale land use planning and management to cultivate more sustainable urban form and settlement patterns became comparatively crowded out. With climate change-related environmental and ecological pressures mounting, the chapter suggests it is time to frame regions as socio-ecological rather than mere socio-economic spaces, thereby placing greater emphasis on ecosystems and ecological land management and a circular, regenerative economy. Using the city-region of Stuttgart (Germany) as exemplar, our contribution initiates an exploration into whether statutory regional planning in combination with various informal tools and a multi-level governance framework allows actors to begin to embed and implement these emerging ecological sustainability concepts.

Abstract
Purpose – The purpose of this chapter is to explore whether and how social tagging can be useful in an information web site for cancer patients and their relatives.
Methodology/approach – Three studies have been carried out in order to investigate the research questions. First, we reviewed and analyzed literature about cancer patients’ information needs and seeking behavior, and about social tagging and patient terminology. Second, we analyzed tags applied to blog postings at Blogomkraeft.dk, a blog site at the Danish information web site Cancer.dk. The tags were compared with the formal browsing structure of Cancer.dk. Results from the two studies were used to develop a prototype for social tagging at Cancer.dk. Thus third, we evaluated the prototype in a usability study.
Findings – We found that tags have the potential to describe and provide access to web site content from the users’ perspective and language use. Social tags may be a means to bridge between scientific viewpoints and terminology and everyday problems and vocabulary. Tags at Blogomkraeft.dk are mainly factual, often detailed, and do not cover as many functions as tags in more general bookmarking systems. An important finding is that some tags seemed to add to and supplement the content instead of factually describing the content of a blog posting. The usability test showed that our test persons liked the tagging feature.
Social implications – Tagging features give the public an opportunity to apply their own terms to documents, reflecting their own model of the current topic. Tags may furthermore function as colloquial lead-in terms from users’ search formulations at search engines such as Google to the domain-specific, tailored cancer web site.
Originality/value – Unlike most research on social tagging so far, we investigate tagging in a domain-specific setting, how tags can improve the interaction and communication between layman users and domain experts in an information web site within health care.

Abstract
Stress and the military go hand-in-hand, particularly in combat environments. While some personality traits or types weaken relationships between stress and performance, others, such as psychopathy, may strengthen them. In the present chapter, we consider the ramifications of individuals with high levels of psychopathy or psychopathic tendencies in the military with regard to both their own stress and performance and that of those around them. We discuss different reactions to psychological and physical stress, as well as the implications of psychopathic tendencies as they relate to current military issues, including gender, leadership, teamwork, turnover, post-traumatic stress disorder, and suicide. By juxtaposing relevant research findings on stress and psychopathy, we conclude that psychopathic tendencies should have neither uniformly negative nor positive effects on stress and performance in the military. Rather, effects on such individuals and the peripheral others with whom they interact will likely vary greatly depending on numerous factors.
