Fibonacci Hierarchies for Decision Making

All decisions are practically made within a chainwise social setup named a decision-making chain (DMC). This paper considers some cases of an idea (a project proposal) propagating through an organizational DMC. Survival of a proposal through successive links of the DMC depends on the relative power of those links, in addition to proposal’s intrinsic value. Then it is not impossible to reject a good proposal or to fail to reject a bad proposal, either of which may generate undesired, though not detrimental, outcomes. We consider here a simple metric to assess quality of decision-making. The notion of quality here derives from “not declining (not accepting) a project that is of high (poor) intrinsic value”. As Fibonacci series establish the mathematical basis of our proposed metric, metric is simply named a Fibonacci metric.Decision making chains; Innovation; Fairness metric; Fibonacci series

Click to Download Data : An Event Study of Internet Access to Economic Statistics

This study examines the online access statistics of the Central Bank of Turkey's Electronic Data Delivery System within an event study framework. The comparisons of pre-event and post-event statistics suggest that announcements of both the policy interest rates and the consumer price data considerably affect society's data access behavior. The timing and amplitude of these effects are further studied with respect to inflation expectations and surprise content of events; yet no solid pattern was revealed.Data access, Macroeconomic data, Market efficiency, Event study

Does Internet access to official data display any regularity: case of the Electronic Data Delivery System of the Central Bank of Turkey

1990s were the years of enormous growth of information exchange. Rapid development, augmented coverage and wide accessibility of Internet have been the key factors of that amazing growth. People’s access to economic and financial data was one of the major areas in which new trends and patterns of usage were observed. Owing to the elevated importance of financial information in today’s sophisticated markets, it is hypothesized that the linkage between data access patterns and economic events should display some regularity. In addition, one should be able to explain part of the irregularities. This study examines the access statistics of the Central Bank of Turkey’s Electronic Data Delivery System on these grounds. Using OLS and EGARCH models, significant evidence was obtained for the existence of regularities (i.e. calendar effects) in the data.Data access; Macroeconomic data; Return to information; Economics of information

In-chip microstructures and photonic devices fabricated by nonlinear laser lithography deep inside silicon

Silicon is an excellent material for microelectronics and integrated photonics1–3 with untapped potential for mid-IR optics4. Despite broad recognition of the importance of the third dimension5,6, current lithography methods do not allow fabrication of photonic devices and functional microelements directly inside silicon chips. Even relatively simple curved geometries cannot be realised with techniques like reactive ion etching. Embedded optical elements, like in glass7, electronic devices, and better electronic-photonic integration are lacking8. Here, we demonstrate laser-based fabrication of complex 3D structures deep inside silicon using 1 µm-sized dots and rod-like structures of adjustable length as basic building blocks. The laser-modified Si has a different optical index than unmodified parts, which enables numerous photonic devices. Optionally, these parts are chemically etched to produce desired 3D shapes. We exemplify a plethora of subsurface, i.e., “in-chip” microstructures for microfluidic cooling of chips, vias, MEMS, photovoltaic applications and photonic devices that match or surpass the corresponding state-of-the-art device performances
