Reviewing, indicating, and counting books for modern research evaluation systems
In this chapter, we focus on the specialists who have helped to improve the
conditions for book assessments in research evaluation exercises, with
empirically based data and insights supporting their greater integration. Our
review highlights the research carried out by four types of expert communities,
referred to as the monitors, the subject classifiers, the indexers and the
indicator constructionists. Many challenges lie ahead for scholars affiliated
with these communities, particularly the latter three. By acknowledging their
unique, yet interrelated roles, we show where the greatest potential is for
both quantitative and qualitative indicator advancements in book-inclusive
evaluation systems.Comment: Forthcoming in Glanzel, W., Moed, H.F., Schmoch U., Thelwall, M.

Mapping the (In)visible College(s) in the Field of Entrepreneurship
Despite the vitality and dynamism that the field of entrepreneurship has experienced in the last decade, the issue of whether it comprises an effective network of (in)formal communication linkages among the most influential scholars within the area has yet to be examined in depth. This study follows a formal selection procedure to delimit the ‘relational environment’ of the field of entrepreneurship and to analyze the existence and characterization of (in)visible college(s) based on a theoretically well-grounded framework, thus offering a comprehensive and up-to-date empirical analysis of entrepreneurship research. Based on more than a thousand papers published between 2005 and 2010 in seven core entrepreneurship journals and the corresponding (85 thousand) citations, we found that entrepreneurship is an (increasingly) autonomous, legitimate and cohesive (in)visible college, fine tuned through the increasing visibility of certain subject specialties (e.g., family business, innovation, technology and policy). Moreover, the rather dense formal links that characterize the entrepreneurship (in)visible college are accompanied by a reasonably solid network of informal relations maintained and sustained by the mobility of ‘stars’ and highly influential scholars. The limited internationalization of the entrepreneurship community, reflected in the almost total absence of non-English-speaking authors/studies/outlets, stands as a major quest for the field.Invisible College; Entrepreneurship; Bibliometrics
Heart failure and cognitive impairment: Challenges and opportunities
As populations age, heart failure (HF) is becoming increasingly common, and in addition to a high burden of morbidity and mortality, HF has an enormous financial impact. Though disproportionately affected by HF, the elderly are less likely to receive recommended therapies, in part because clinical trials of HF therapy have ignored outcomes of importance to this population, including impaired cognitive function (ICF). HF is associated with ICF, manifested primarily as delirium in hospitalized patients, or as mild cognitive impairment or dementia in otherwise stable outpatients. This association is likely the result of shared risk factors, as well as perfusion and rheological abnormalities that occur in patients with HF. Evidence suggests that these abnormalities may be partially reversible with standard HF therapy. The clinical consequences of ICF in HF patients are significant. Clinicians should consider becoming familiar with screening instruments for ICF, including delirium and dementia, in order to identify patients at risk of nonadherence to HF therapy and related adverse consequences. Preliminary evidence suggests that optimal HF therapy in elderly patients may preserve or even improve cognitive function, though the impact on related outcomes remains to be determined
The structural role of the core literature in history
The intellectual landscapes of the humanities are mostly uncharted territory.
Little is known on the ways published research of humanist scholars defines
areas of intellectual activity. An open question relates to the structural role
of core literature: highly cited sources, naturally playing a disproportionate
role in the definition of intellectual landscapes. We introduce four indicators
in order to map the structural role played by core sources into connecting
different areas of the intellectual landscape of citing publications (i.e.
communities in the bibliographic coupling network). All indicators factor out
the influence of degree distributions by internalizing a null configuration
model. By considering several datasets focused on history, we show that two
distinct structural actions are performed by the core literature: a global one,
by connecting otherwise separated communities in the landscape, or a local one,
by rising connectivity within communities. In our study, the global action is
mainly performed by small sets of scholarly monographs, reference works and
primary sources, while the rest of the core, and especially most journal
articles, acts mostly locally
