We discuss the way of hoax spreading as gossip and rumor throughout the social media, i.e.: Twitter, by observing an empirical case in Indonesia. We discuss the spreading factor of the gossip in the social media and see the epidemiology of the propagation hoax before and after the hoax being...

A lot of changing in recent Indonesian political dynamics with eventual fact shows how political recruitment for legislative and executive chairs in national as well as regional levels in direct voting systems have brought the patterns of coalitions among political parties into interesting focus...

The debate over the Phillips Curve - as the relation between level of unemployment rate and inflation rate - in historical economics is shortly reviewed. By using the analysis in the Extreme Value Theory, i.e.: the rank order statistics the unemployment and inflation data over countries from...

The paper conjectures some alternative acquisitions of mathematical models to see the Batak family tree that could enrich our understanding of the anthropological study of Bataknese people. We discuss some aspects of Bataknese Clan-group in Batak traditional social life. Since the family tree is...

The paper introduces the organization concept of silaturahmi that widely used as an important concept to maintain a lot of community structures in Indonesia. One of the organization is alumni forum where alumni gathers and establishes an institutional organization. The concept of silaturahmi is...

We continue some steps showing the distinctions and proximities of languages over statistical facts as it has been pioneered previously [3]. In the paper, we construct the homology tree from the distance matrix yielded from the transformation of some statistical aspects of the empirical...

The short paper presents interesting discussions related to specific Indonesian legislative election system. We build algorithmic steps in computational geometry that employ the basic patterns that emerged from the legal decisions of Indonesian General Election Commission about the election...

The paper introduces the presence of three statistical regimes in the Zipfian analysis of texts in quantitative linguistics: the Mandelbrot, original Zipf, and Cancho- Soleacute;-Montemurro regimes. The work is carried out over nine different languages of the same intention semantically: the...
