Franz Rothlauf gave a doctoral class on "Design and Application of Modern Heuristics" in Mainz between October 6-9, 2014

The course is part of the doctoral program of the German Academic Association for Business Research (VHB)
(http://vhbonline.org/en/events/the-doctoral-program/) and can be used at many European universities with 6 ECTS credit points.

Besides learning how to apply metaheuristics, the interactive 4-day course dealt with the following questions:
1. How to select among different metaheuristics?
2. How to design efficient metaheuristics?
3. How to consider problem-specific knowledge for the design of metaheuristics?

There were nine participants from different universities in Germany and Switzerland. On Wednesday evening, the class had a sightseeing tour through Mainz and visited a traditional vine restaurant. A new edition of the course will be offered in autumn 2015 or 2016. More infos can be found at http://vhbonline.org/veranstaltungen/doktorandenprogramm/kursuebersicht/mh140/

Three outstanding doctoral theses at the chair of Information Systems and Business Admininstration – Congratulations

In September 2014 three theses have been successfully completed at the chair of Information Systems and Business Administration.

Mr. Nicco Graf completed his cumulative dissertation with the title “Securing Supporters’ Commitment in Firm-NGO Collaborations: The NGO Perspective”. He addressed the question of how non-governmental organizations can establish a strategic change concerning collaborations with firms without putting NGO member’s approval at risk. He pursued this question in a comprehensive experimental and empirical study go on reading

Facebook recommendations could be worth millions of euros - Study confirms online sales are enhanced by social recommendations and determines the actual value of "likes"

When online retailers display customer recommendations next to their product descriptions, it can significantly increase the sales of these. This is the conclusion reached following a study undertaken by academics at Johannes Gutenberg University Mainz (JGU) and the Technische Universität (TU) Darmstadt. They conducted an experiment in cooperation with an online mail order company to determine whether product recommendations by customers have an impact on other customers' buying behavior.

Amazon and Apple fence off their e-book markets - Researchers from Mainz University hand over their recommendation of the EPUB3 standard to Neelie Kroes, EU Commissioner for the Digital Agenda

There are no technical or functional reasons for Amazon and Apple to fence off their e-book worlds using proprietary e-book formats. This is the result of a research study conducted by Professor Dr. Christoph Bläsi and Professor Dr. Franz Rothlauf of Johannes Gutenberg University Mainz (JGU) and handed over today to Neelie Kroes, EU Commissioner for the Digital Agenda, in Brussels. The researchers emphasize the fact that the format standard proposal EPUB3 supports all features needed for multimedia and interactive e-books. Amazon and Apple, however, use other formats that are incompatible with that of most independent retailers and are thus limiting users to the products of their respective e-book stores.

In their study, commissioned by the European and International Booksellers Federation (EIBF), Professor Dr. Christoph Bläsi of the JGU Institute of Book Studies and Professor Dr. Franz Rothlauf of the Gutenberg School of Management and Economics also discuss the fact that the industry-wide use of the EPUB3 standard alone would not guarantee the complete interoperability of e-books for consumers. The digital rights management measures of the different publishing worlds would have to be synchronized. The study holds that this would be feasible, given the corresponding will of the parties concerned.

The 48-page study on the current interoperability of e-book formats has today been handed over to Neelie Kroes, Vice-President of the EU Commission for the Digital Agenda. It is to contribute to the creation of a barrier-free market for e-books.

On the interoperability of e-books formats

A study into interoperability of e-book formats unveiled at the EIBF Annual Conference, Brussels, 16 May 2013, commissioned from Johannes Gutenberg University Mainz by the European & International Booksellers Federation

The study was conducted by Professor Christoph Bläsi and Professor Franz Rothlauf of Johannes Gutenberg University, who said: "There is no technical or functional reason not to use and establish EPUB 3 as an/the interoperable (open) ebook format standard.

One short term obstacle is the non-availability of reader applications able to display all EPUB 3 features. However, this problem should be fixed soon by the IDPF Readium initiative which is developing an open source reference system and rendering engine for EPUB 3."

Vice-President of the European Commission, Neelie Kroes, in charge of the Digital Agenda, praised the study: "My wish is that booksellers in Europe can take initiatives and benefit from the growth in the ebook markets. This is why I welcome this study by the European Booksellers Federation. Interoperability is a major requirement to build a truly digital society. This applies to ebooks too. This study provides interesting insights on ways to reach true interoperability in the ebook market, through both interoperable ebook formats and interoperable DRM schemes. Now is the time for open standards regarding ebooks, just like has happened in other areas of the digital economy."

John Mc Namee, President of the European Branch, EBF, said: "The lack of interoperability between formats and platforms has been identified as one of the major obstacles hindering the Digital Agenda and is a real problem for booksellers in their daily contacts with their customers. On behalf of my colleagues from all Booksellers Associations in membership with EBF, I am very pleased that this study provides clear scientific evidence that interoperability is achievable. It also shows that there are alternatives to DRM's and that content portability is feasible. Booksellers are keen to promote business models which make digital content easily accessible to the customers they are in touch with on a daily basis in their terrestrial or e-bookshops, the European readers.

Equally, booksellers are keen to sell e-books across borders and make as many customers as possible happy. They strongly support an open market, without territorial restrictions, in the full respect of copyright".
