title: Searching for rational bubble footprints in the Singaporean and Indonesian stock markets

authors: Nartea, Gilbert V.

abstract: We re-examine the presence of rational speculative bubbles in the Singaporean and Indonesian stock markets in light of contradictory results in the literature. We employ a mix of descriptive statistics, explosiveness tests and duration dependence tests for an expanded dataset from 1970 to 2013 that covers at least two suspected bubble episodes - the 1997 Asian Financial Crisis (AFC) and the Global Financial Crisis (GFC). We find bubble footprints in Singapore and Indonesia using descriptive statistics and explosiveness tests. However, we find no evidence of rational bubbles in Singapore using the duration dependence test. On the other hand, in Indonesia we find evidence of rational bubbles in weekly but not in monthly data. Our results indicate that the duration dependence test could be sensitive to data frequency suggesting that the duration dependence test results are not always conclusive and that it should be used in conjunction with other tests.

title: Design and the fourth industrial revolution. Dangers and opportunities for a mutating discipline

authors: García Ferrari, Tomás

subjects: Design

abstract: The nature of design has always been related to socio-technological forces. In the twentieth century, the first and second orders of design were central in the establishment of graphic and industrial design. In the early years of the twenty-first century, the third and fourth orders of design were related to interactions and environments. This description can be associated with different phases of the Industrial Revolution: the first two phases allowed the transition from a farming and feudal society to an industrial and capitalist one, a third one was related to a post-industrial or services society. The Fourth Industrial Revolution presents the Internet, 3D printers and genetic algorithms as the main technical achievements and green energies as the energy source. It is related to computers, software, artificial intelligence, the Internet of Things and machine learning. These technological forces will create the space for the most important design jobs of the future.
