Purpose: This study aims to analyze the indicators that play a role in Indonesian marine and fisheries sector's development (investment sector, trade openness, net exports, global value chain (GVC) fish production) towards gross domestic product (GDP) of sector. Theoretical framework: The theoretical framework builds on New Trade Theory (NTT), sustainable ocean economy, chains. Design/methodolo...

Facebook has become a leading avenue for online brand communities (i.e., fan pages) that are used for marketing purposes. Despite the popularity on Facebook, there has been limited empirical research regarding the dynamics of firm-generated content (FGC) and user-generated content (UGC) over a long period of time at the industry level. The objective of this paper is to examine the dynamics of t...

In this paper, we propose a new entropy-optimized bivariate empirical mode decomposition (BEMD)-based model for estimating portfolio value at risk (PVaR). It reveals and analyzes different components of the price fluctuation. These components are decomposed and distinguished by their different behavioral patterns and fluctuation range, by the BEMD model. The entropy theory has been introduced f...

This paper considers multiobjective linear programming problems (MOLPP) where random fuzzy variables are contained in objective functions and constraints. A new decision making model optimizing possibilistic value at risk (pVaR) is proposed by incorporating the concept of value at risk (VaR) into possibility theory. It is shown that the original MOLPPs involving random fuzzy variables are trans...

Abstract The objective of this study is to contribute the knowledge about relationship between financial inclusion and credit risk in Southern African Development Community ( SADC ) countries, which remains relatively unexplored developing countries context. result panel vector autoregressive models PVAR estimation shows that there no bidirectional causality risk, but unidirectional where impro...

A thought experiment first proposed by Sartori is analysed using the parallel velocity addition formula of special relativity. The spatial and proper-time intervals between some similarly defined spatial coincidence events are found to be widely different in different inertial frames. This relativity of space and time intervals is quite distinct from the well-known time-dilatation and length co...
