10 excellent iPad apps to annotate, highlight, and add comments to PDFs






The ‘HEC Paris Research Paper Series’

HEC Paris launched its own SSRN collection in January 2013, called the ‘HEC Paris Research Paper Series.’  Thanks to the support of researchers, professors and collaborators, Hec Paris  has managed to rise from 33rd to 14th place  in terms of the total number of publication downloads in the last 12 months. (data acquired from SSRN rankings)

This year, 101 documents have been deposited in the repository, compared to 52 in 2012; an increase by almost double, placing HEC Paris in 15th place in terms of new documents uploaded.

The complete collection of 568 documents, of which at least one author is affiliated with HEC Paris today represents 161,900 downloads – an average of 285 downloads per document and 26 citations per author .

To enable HEC Paris to maintain or even improve its ranking and to allow authors to improve their visibility, it is important to continue this trend and increase the number of submissions. The library is at the disposal of academics who have any questions about the legal aspects of copyright relating to pre-prints or technical aspects of deposit on SSRN . Contact: Lydia Tournaire .

Can you submit a forthcoming paper on SSRN ?

Yes, you can!

A forthcoming article, (an article with confirmed publication in the press) may be deposited on SSRN under the terms of copyright according to each specific journal or publisher as a pre or post –print version. For copyright rules specific to each review, you can visit Sherpa Romeo for reference, or view some of our previous blog posts

The screen shot example below shows a summary of the copyright policies for the Journal of Economic Theory.


This review permits the submission of pre-print (ie pre- referral ) on all websites or open access sites, post -print ( ie final draft post- referral) but does not allow the editors’ final PDF pdf version to be uploaded.

Do not hesitate to contact the library with any questions about forthcoming articles on SSRN .
When querying information collected on the Sherpa / Romeo site, we carefully study journal guidelines available on their website or, if necessary, we ask them to let us know directly.

Have you heard of CitNetExplorer?

What is CitNetExplorer?


CitNetExplorer is ‘a software tool for visualizing and analyzing citation networks of scientific publications.’

The software allows the user to import citation networks straight from the Web of Science database, for example, which HEC subscribes to, alongside citation imports from millions of other publications and citations.

These networks can then be explored interactively. The user is able to identify related publications and cited works using the graphic, find direct and indirect citation relations and apply different algorithms to limit results, such as by publication date or to identify connected components. They can also be exported in Pajek format for further consultation.


Why use CitNetExplorer?

CitNetExplorer uses citations to identify relationships between different publications or authors. This makes it possible to:

  • Analyze or follow developments in a specific research domain over time.
  • Identify the literature available on a specific research topic.
  • Explore the range publications from a researcher.
  • Review literature in a given field

Cairn – new international site and user interface

Cairn is a collection of humanities and social sciences publications in French, which the HEC library subscribes to.

Created in September 2005 by four Belgian and French publishers, today Cairn offers the most comprehensive collection of publications to the francophone world.

In 2014, they expect to hold 400 journals, around 4,000 eBooks and more than 200,000 full-text articles and book chapters online, from major French, Belgian and Swiss publishers.

They have recently introduced two new functions:

  • A new ‘cleaner’ interface offering the ability to search by theme from the home page (as pictured)
  • An international version of its site, offering the same service to English speakers, launched with the support of the CNL (The French Centre National du Livre).


This should allow this content to become more visible and accessible to non–francophone scholars, as no understanding of the French language is required, and should help promote Cairn’s popularity to at least that equal to that achieved by its existing French site which received over 20 million views last year.

Do not hesitate to contact the library for further help on this resource.

On The Future Of Statistical Languages

Seth Brown, a data scientist in the telecommunications industry, has recently written an article on his blog entitled ‘On The Future Of Statistical Languages’

This article analyses the current state of statistical languages in use, and gives a justified response in predicting the future path in this field.

There currently exists a crossover between programming and statistical languages, with most statistics languages containing limited programming functions and vice versa. In order for this area to further develop, bridges need to be built to improve this crossover and make each area less exclusive, with a view to creating ‘an efficient, modern data analysis workflow’

Taking the authors example, use of languages ‘R’ and ‘Python’ amongst others, and the need to transfer between them top complete different tasks within the framework of the same project is inefficient. Whilst not intending to critique the current languages on offer, the author goes on to advocate ‘rich data analysis API no top of a more general open source programming language’.

But what does this mean for the future?

New inventions, technologies and increased reliance on digital devices mean that the amount of data collected is growing exponentially. To this end, the author proposes languages to focus on the statistical side, and to leave ‘the nuts and bolts’ of language design to its own experts. The language needs to be easy to understand, and approachable for students/statisticians/scientists using it so that they can build on the data collected and methodology instead of focusing on the language.

It should be free. Similar to current examples such as MATLAB, SPSS and Stata, to prevent monopolization and ensure that data can be shared across platforms and research can be advanced, avoiding as the author suggests, ‘The Microsoft Word problem’.

New tools should not be limited by domain specific languages or sunken-cost projects – as the Haskell case has proved.

The author then, suggests that going forward, ‘Python is the most obvious choice’ as it is currently already widely used, and already has tools in place. But even this needs improving in terms of accessibility to non-programmers, adopting a more user friendly environment, and deeper reach into academia, and thus instigate the construction of the programming-statistical bridge.
