Microsoft Academic Search and Google Scholar Citations
Microsoft Academic Search and Google Scholar Citations Microsoft Academic Search and Google Scholar Citations: A comparative analysis of author profiles José Luis Ortega1 VICYT-CSIC, Serrano, 113 28006 Madrid, Spain, [email protected] Isidro F. Aguillo Cybermetrics Lab, CCHS-CSIC, Albasanz, 26-28 28037 Madrid, Spain, [email protected] Abstract This paper aims to make a comparative analysis between the personal profiling capabilities of the two most important free citation-based academic search engines, namely Microsoft Academic Search (MAS) and Google Scholar Citations (GSC). Author profiles can be very useful for evaluation purposes once the advantages and the shortcomings of these services are described and taken into consideration. A total of 771 personal profiles appearing in both the MAS and the GSC databases are analysed. Results show that the GSC profiles include more documents and citations than those in MAS, but with a strong bias towards the Information and Computing sciences, while the MAS profiles are disciplinarily better balanced. MAS shows technical problems such as a higher number of duplicated profiles and a lower updating rate than GSC. It is concluded that both services could be used for evaluation proposes only if they are applied along with other citation indexes as a way to supplement that information. Keywords: Microsoft Academic Search; Google Scholar Citations; Web bibliometrics; Academic profiles; Research evaluation; Search engines Introduction In November 2009, Microsoft Research Asia started a new web search service specialized in scientific information. Even though Google (Google Scholar) already introduced an academic search engine in 2004, the proposal of Microsoft Academic Search (MAS) went beyond a mere document retrieval service that counts citations. -

Although these have been compared to the Web of Science (WoS), Scopus, or Google Scholar, there is no systematic evidence of their differences across subject categories. Methods In response, this paper investigates 3,073,351 citations found by these six data sources to 2,515 English-language highly-cited documents published in 2006 from 252 subject categories, expanding and updating the largest previous study. Results Google Scholar found 88% of all citations, many of which were not found by the other sources, and nearly all citations found by the remaining sources (89%-94%). A similar pattern held within most subject categories. Microsoft Academic is the second largest overall (60% of all citations), including 82% of Scopus citations and 86% of Web of Science citations. In most categories, Microsoft Academic found more citations than Scopus and WoS (182 and 223 subject categories, respectively), but had coverage gaps in some areas, such as Physics and some Humanities categories. -
Brain Ageing in the New Millennium
Brain ageing in the new millennium Julian N. Trollor, Michael J. Valenzuela Objective: This paper examines the current literature pertaining to brain ageing. The objective of this review is to provide an overview of the effects of ageing on brain structure and function and to examine possible mediators of these changes. Methods: A MEDLINE search was conducted for each area of interest. A selective review was undertaken of relevant articles. Results: Although fundamental changes in fluid intellectual abilities occur with age, global cognitive decline is not a hallmark of the ageing process. Decline in fluid intellectual ability is paralleled by regionally specific age related changes apparent from both structural and functional neuroimaging studies. The histopathological mediators of these changes do not appear to be reduction in neuronal number, which, with the exception of selected hippo- campal regions, remain relatively stable across age. At the molecular level, several mech- anisms of age related change have been postulated. Such theoretical models await refinement and may eventually provide a basis for therapy designed to reduce effects of the ageing process. The role of possible protective factors such as ‘brain reserve’, neuro- protective agents and hormonal factors in modifying individual vulnerability to the ageing process has been the focus of a limited number of studies. Conclusion: Our understanding of the functional and structural changes associated with both healthy and pathological ageing is rapidly gaining in sophistication and complexity. An awareness of the fundamental biological substrates underpinning the ageing process will allow improved insights into vulnerability to neuropsychiatric disease associated with advancing age. Key words: brain ageing, cognition, dementia, neuroimaging. -

The Effects of Normal Aging on Myelin and Nerve Fibers: a Review∗
Journal of Neurocytology 31, 581–593 (2002) The effects of normal aging on myelin and nerve fibers: A review∗ ALAN PETERS Department of Anatomy and Neurobiology, Boston University School of Medicine, 715, Albany Street, Boston, MA 02118, USA [email protected] Received 7 January 2003; revised 4 March 2003; accepted 5 March 2003 Abstract It was believed that the cause of the cognitive decline exhibited by human and non-human primates during normal aging was a loss of cortical neurons. It is now known that significant numbers of cortical neurons are not lost and other bases for the cognitive decline have been sought. One contributing factor may be changes in nerve fibers. With age some myelin sheaths exhibit degenerative changes, such as the formation of splits containing electron dense cytoplasm, and the formation on myelin balloons. It is suggested that such degenerative changes lead to cognitive decline because they cause changes in conduction velocity, resulting in a disruption of the normal timing in neuronal circuits. Yet as degeneration occurs, other changes, such as the formation of redundant myelin and increasing thickness suggest of sheaths, suggest some myelin formation is continuing during aging. Another indication of this is that oligodendrocytes increase in number with age. In addition to the myelin changes, stereological studies have shown a loss of nerve fibers from the white matter of the cerebral hemispheres of humans, while other studies have shown a loss of nerve fibers from the optic nerves and anterior commissure in monkeys. It is likely that such nerve fiber loss also contributes to cognitive decline, because of the consequent decrease in connections between neurons.
