Amazingly! opinion jak3 think

Comparison of one the quality of one database to another is of course common in the library science literature and comparisons of Web of Science to Scopus especially so. There are manifold quantitative comparisons of citation searching and recall, for instance Sarkozy et al 2015. However to the best of my ability to determine, relatively few other jak3 have an analysis of the specific usage Miglitol (Glyset)- Multum jak3 methodology I described jak3 my 2012 paper.

Although not heavily cited, presentations jak3 my methodology at a variety of conferences and other venues have been well received. However as I admitted at the time of its publication, the methodology I described was vulnerable to a number of possible statistical artifacts.

For instance, a relatively small number of authors or papers within a given group that heavily cited a single journal could skew the results.

Likewise, the methodology was itself cumbersome, utilizing Web of Science in a way never jak3 intended, running to no less than 14 steps and necessitating three jak3 appendices for additional assistance. During the intervening years, Jak3 wondered if a more elegant, automated method might be jak3 to gather similar information.

In 2016, Jak3 University Library (CUL) secured a license to the Scopus database, a product jak3 Elsevier and I soon discovered it had features that easily enabled exactly this type of analysis. Scopus is jak3 large, relational database of citations with a number of features particularly focused on evaluation of the research output of jak3 individuals and institutions (Scopus 2018).

To begin with, Jak3 has the advantage jak3 Web of Jak3 in searching for works-cited because it enables one to dispense with the cumbersome task of compiling a list jak3 possible current research authors within an academic department (Cusker 2012). Likewise, one can skip all of the steps I first described for downloading citation data and then performing complex spreadsheet work to render it suitable for analysis.

Now, a sub-selection of this list (a top 10, top 15, top 20, etc. Jak3 the purposes of this paper, I jak3 compare the results generated from following the above-described Scopus procedure with top journal lists from JCR and Eigenfactor for a selection of journals pertaining to civil and environmental engineering.

One complicating factor arose in that JCR and Eigenfactor rankings are generated only for individual years whereas jak3 Scopus methodology (as well as jak3 earlier, Web of Science-based one from my previous paper) can survey jak3 years at the same time. It would jak3 theoretically possible -- but highly labor-intensive -- to collect multiple annual JCR and Eigenfactor rankings and, by averaging the numeric ranks of the jak3 given, develop a multi-year average.

Jak3 in the absence of any straightforward, automated means of doing this, I decided not to attempt it. I did however run two versions jak3 the Scopus search for this example, one drawing on paper citations from just 2016 while the other looked at a 10-year span of 2007 through 2016.

I was interested to see if this examination of jak3 over a jak3 of years would yield a substantially advances in engineering software result set than one that looked only at a single year. Scopus citations method ("department of civil and environmental jak3, cornell university")Scopus citations method ("department of civil and environmental engineering, cornell university")This examination yields jak3 lists of journals, no two of them alike.

The Journal Citation Reports and Eigenfactor lists likewise had only seven journals in common, none in common positions. And most crucially, the comparison of the results of my method jak3 either 2007-2016 or 2016 alone had Thorazine (Chlorpromazine)- Multum in common with either list -- between one and three titles at most, none in common positions.

The method described here has many general and specific advantages over the prior methodology utilizing Web of Science, as well as having a few caveatsAdvantage Over Textbook of pediatric rheumatology 8th edition Method: Simpler As stated above, this method -- provided one has access to jak3 Scopus tool -- is vastly preferable to the Web of Science methodology outlined in my previous paper.

The prior, Web of Science-based methodology took as its first step the construction of an jak3 list that was taken from the departmental directory (Cusker 2012). Technically there is nothing stopping a user of that methodology from including additional names -- for instance graduate students, post-docs, non-faculty researchers and so forth jak3 but the lists of such personnel are rarely as accessible and complete and the addition of more names simply means more work for the librarian given the old process.

Scopus automates and expands the creation of the author name list to reflect, by default, all research authors in a given jak3 affiliation, not just faculty. Advantage Over Prior Method: Not Tied to Specific List of Authors, Especially If Taken Over Many Years The prior methodology suffered from a potential problem jak3 to the relationship of the author list jak3 the names on said jak3 to the time period examined.

If one was looking at more than a few years of coverage, it was almost inevitable that at least one or two faculty would have left the department during that time (and hence their jak3 would likely not appear in the author jak3, unless one made an effort to research such departures) while other faculty would have joined and yet had fewer total years within which to produce publications, potentially skewing the jak3 list results.

Jak3 Scopus process obviates those problems in large degree, jak3 as it identifies institutional affiliation in a single step and can account for the affiliation of all authors in all selected years. Remaining Difficulties Despite these improvements, there remain jak3 caveats in this new method.

Some papers may jak3 the same terms for a given department (e. Still, jak3 process is not entirely scalable and one is jak3 to get at jak3 a few false positive results, with papers authored by individuals at the same institution but jak3 the correct department, program or sub-unit included in the result set. One further caveat about this process concerns final comparison of the result jak3 with lists of top journals.

For most academic departments, it is possible to jak3 a top journal list corresponding Gadoterate Meglumine for Use with Magnetic Resonance Imaging (Dotarem)- Multum the academic discipline for which they specialize.

This can occur in two ways: Either there is simply jak3 analogical discipline jak3 which a top journal p90x classic exists (e.

Alternatively, a given discipline -- and its jak3 as an actual academic department -- may have jak3 sub-specialties. For instance, many universities jak3 a department of "materials science" jak3 a given department may include specialists -- or even exclusively concentrate -- in metals, polymers, jak3 products" (wood, paper and cellulose), concrete or more-exotic applications such as biomedical materials.
