Does a Leapfrogging Growth Strategy Raise Growth Rate? Some International Evidence

While openness to trade is a well-recognized hallmark of the Asian growth model, another component of the model is a leapfrogging strategy—the use of policies to guide industrial structural transformation ahead of a country's factor endowment. Does the leapfrogging strategy work? Opinions vary but the evidence is scarce in part because it is more difficult to measure the degree of leapfrogging than the extent of trade openness. We undertake a systematic look at the evidence both across countries and subregions within a large regional Asian economy to assess the efficacy of such a strategy. We conclude that there is no strong and robust evidence that this strategy works reliably.growth; trade openness; leapfrogging

Does a Leapfrogging Growth Strategy Raise Growth Rate? Some International Evidence

While openness to trade is a well-recognized hallmark of many successful emerging market economies known as “growth miracles,” another component of the growth model is a leapfrogging strategy – the use of policies to guide the industrial structural transformation ahead of a country's factor endowment. Does the leapfrogging strategy work? Opinions vary but the evidence is scarce in part because it is more difficult to measure the degree of leapfrogging than the extent of trade openness. We undertake a systematic look at the evidence across countries to assess the efficacy of such a strategy. So far, there is no strong and robust evidence that this strategy works reliably. Future research can explore a number of refinements.

The relationship between innovation & dynamic capability : Malaysia perception/view

Purpose – The purpose of this paper is to provide better insights into the relationship between dynamic capabilities and innovation. It links dynamic capability with innovation and indicates the ways they can be related. Design/methodology/approach – The relationships between dynamic and innovation capability were investigated through a systematic literature review as well as through non-parametric correlation testing. Findings – Non-parametric testing of correlation shows positive relationship between innovation and dynamic capability, furthermore it result shows among the three types of innovation (Product &service innovation, Process innovation, Marketing innovation) only process innovation is significantly related to dynamic capability. However, both finding shows several inconsistencies and even contradictions. Originality/value – In this paper, the authors attempts to provide a better clarification as the relationship between dynamic capabilities with innovation, both of which is relatively new approach in the field of strategic management. Since both areas address issues that are essential to today’s environment, future research should seek to clarify both concepts, by undertaking some new method of research and developing a more comprehensive and unambiguous framework

Waveform Design of DFRC System for Target Detection in Clutter Environment

Dual-function radar and communication (DFRC) has recently drawn significant attention due to its enormous potential. This letter deals with waveform design of DFRC to improve target detectability embedded in clutter environment while guaranteeing the service quality of communication users. Our design objective is to maximize the output signal-to-clutter-plus-noise ratio (SCNR) of multiple-input multiple-output (MIMO) radar, subject to worst-case received symbol errors at communication users. Coordinate descent (CD) as an efficient iteration algorithm is proposed to solve above optimization problem, which splits high-dimensional problem into multiple one-dimensional problem. Furthermore, we introduce Dinkelbach algorithm (DA) to increase rate of convergence, which is an efficient way to reduce complexity. Finally, simulation results are presented to illustrate the effectiveness of the proposed techniques

User-Centric Networking for Dense C-RANs: High-SNR Capacity Analysis and Antenna Selection

IEEE Ultra-dense cloud radio access networks (C-RANs) is one of the architectures that will be critical components of the next-generation wireless systems. In a C-RAN architecture, an amorphous cellular framework, where each user connects to a few nearby remote radio heads (RRHs) to form its own cell, appears to be promising. In this paper, we study the ergodic capacity of such amorphous cellular networks at high signal-tonoise ratios (SNRs) where we model the distribution of the RRHs by a Poisson point process. We derive tractable approximations of the ergodic capacity at high-SNRs for arbitrary antenna configurations, and tight lower bounds for the ergodic capacity when the numbers of antennas are the same at both ends of the link. In contrast to prior works on distributed antenna systems, our results are derived based on random matrix theory and involve only standard functions which can be much more easier evaluated. The impact of the system parameters on the ergodic capacity is investigated. By leveraging our analytical results, we propose two efficient scheduling algorithms for RRH selection for energy-efficient transmission. Our algorithms offer a substantial improvement in energy efficiency compared to the strategy of connecting a fixed number of RRHs to each user

Functional Effects of let-7g Expression in Colon Cancer Metastasis.

MicroRNA regulation is crucial for gene expression and cell functions. It has been linked to tumorigenesis, development and metastasis in colorectal cancer (CRC). Recently, the let-7 family has been identified as a tumor suppressor in different types of cancers. However, the function of the let-7 family in CRC metastasis has not been fully investigated. Here, we focused on analyzing the role of let-7g in CRC. The Cancer Genome Atlas (TCGA) genomic datasets of CRC and detailed data from a Taiwanese CRC cohort were applied to study the expression pattern of let-7g. In addition, in vitro as well as in vivo studies have been performed to uncover the effects of let-7g on CRC. We found that the expression of let-7g was significantly lower in CRC specimens. Our results further supported the inhibitory effects of let-7g on CRC cell migration, invasion and extracellular calcium influx through store-operated calcium channels. We report a critical role for let-7g in the pathogenesis of CRC and suggest let-7g as a potential therapeutic target for CRC treatment
