Abstract
Purpose
To present YouFlow Microblog and how its functionalities for discourse structuring and message classification allows improving learning. The paper aims to discuss these issues.
Design/methodology/approach
The authors developed a survey on microblogs and its functionalities for supporting education, and then the authors developed a new microblog called YouFlow Microblog, which was used in a case study to illustrate its applicability.
Findings
The results were: the categorization of messages according to the lesson plan allowed deeper discussions; the amount of messages and preference of the students for the categorization approach are directly related; the filtering of messages (categorization on the reading time) was used as a facilitator of the discussion understanding; the students prefer the search results organized by the categories and related messages; and the students were able to follow the discussions supported by the tree structure of discourse, categorization of messages according to the lesson plan and searches or filtering of messages.
Research limitations/implications
Other case studies involving more students and from different knowledge areas could be performed. Other approaches for messages' visualization for reducing the amount of information could be explored, such as recommendation of messages in microblogs; and groupings of messages according to date, priority and subject.
Practical implications
The developed microblog is useful and proved to be interesting for applying in the educational context.
Originality/value
No other microblog allows different structuring of messages and the their classification according to the lesson plan, in addition to filtering and query functionalities.

Abstract
Using a sample of 86 countries over the 1960–1999 period, this paper investigates the differential growth effects of ethnic division across cultural regions. While the evidence supports a negative relationship between ethnic fragmentation and economic growth, this relationship is significant only for Africa and Latin America. This study also uses a religious measure of ethnic fragmentation, and finds that religious diversity has a positive impact on growth. This impact, however, is present only in the Middle East and East Asia. Some possible reasons behind the heterogeneous effects of ethnic diversity are also explored.

This study aims to develop a proprietary indicator to measure the digital presence of the institutions: the digital presence index.
Abstract
Purpose
This study aims to develop a proprietary indicator to measure the digital presence of the institutions: the digital presence index.
Design/methodology/approach
This research delves into how nonprofit institutions, specifically business interest associations (BIAs), have developed their internet presence by applying essential digital marketing techniques. To this end, and using big data mining tools, this study analyzes the tracking by internet users of 102 BIAs, with their respective websites in 36 countries in Europe and the USA. In addition, the presence and activity of the institutions included in this study on social networks are considered.
Findings
This research serves as a basis for discussing the current gap between social reality and the digitalization of institutions. In this sense, conclusions are drawn on the importance of managerial profiles in decision-making on digitization and the necessary knowledge that, together with Web and social network managers, they must have to articulate the means and techniques that promote the internet presence of the organizations they manage.
Originality/value
Conclusions are drawn according to the geographical scope of the BIAs, and an argument is made about the difficulties of connection and loss of prominence of this type of institutions among their different target audiences, especially among the youngest and most digitized.
