Foreign Direct Investment â Growht Nexus: A Review of The Recent Literature
This paper reviews the literature dealing with the effects of FDI on Growth. Numerous empirical studies have been conducted to investigate whether growth is influenced by FDI. The overall evidence is best characterized as mixed as the results are regarding to the importance of labor costs, openness, investment climate, countries considered (developed vs developing) and fiscal incentives. However, free trade zones, trade regime, the human capital base in the host country, financial market regulations, banking system, infrastructure quality, tax incentives, market size, regional integration arrangements and economic/political stability are very important determinant for FDI that creates a positive impact on overall economic growth. In summary, consensus has been reached among academia and practitioners that FDI tends to have significant effect on economic growth through multiple channels such as capital formation, technology transfer and spillover, human capital (knowledge and skill) enhancement, and so on.FDI, Economic Growth
The sustainable development of mobility in the green transition: Renewable energy, local industrial chain, and battery recycling
The transportation sector has a strong negative impact on the environment and
therefore requires new sustainable development measures. This paper proposes a
new indicator of sustainability in transport obtained through a multi-criteria analysis
based on Eurostat data and a panel of 10 academics. The results show a positive per formance of Sweden in the period 2015â2019 and a small number of countries
above the European average. Furthermore, a quantitative analysis based on these
experts identifies the critical success factors associated with purchasing electric vehi cles. The greatest importance is assigned to purchase cost, followed by battery
autonomy. Our analysis proposes that electric vehicles are unable to achieve a sus tainable transition unless three conditions are met: (i) use of renewable sources,
(ii) local industrial development of the sector, and (iii) battery recycling. Therefore,
Europe urgently needs to realize new industrial activities and avoid social unsustain ability. The long-term objective of a policy plan is to promote independence from external sources of energy, materials, and other resource
Energy reduction in 3D NoCs through communication optimization
Cataloged from PDF version of article.Network-on-Chip (NoC) architectures and three-dimensional (3D) integrated circuits have been introduced as attractive options for overcoming the barriers in interconnect scaling while increasing the number of cores. Combining these two approaches is expected to yield better performance and higher scalability. This paper explores the possibility of combining these two techniques in a heterogeneity aware fashion. Specifically, on a heterogeneous 3D NoC architecture, we explore how different types of processors can be optimally placed to minimize data access costs. Moreover, we select the optimal set of links with optimal voltage levels. The experimental results indicate significant savings in energy consumption across a wide range of values of our major simulation parameters
Single Tree Vegetation Depth Estimation Tool for Satellite Services Link Design
Attenuation caused by tree shadowing is an important factor for describing the propagation channel of satellite services. Thus, vegetation effects should be determined by experimental studies or empirical formulations. In this study, tree types in the Black Sea Region of Turkey are classified based on their geometrical shapes into four groups such as conic, ellipsoid, spherical and hemispherical. The variations of the vegetation depth according to different tree shapes are calculated with ray tracing method. It is showed that different geometrical shapes have different vegetation depths even if they have same foliage volume for different elevation angles. The proposed method is validated with the related literature in terms of average single tree attenuation. On the other hand, due to decrease system requirements (speed, memory usage etc.) of ray tracing method, an artificial neural network is proposed as an alternative. A graphical user interface is created for the above processes in MATLAB environment named vegetation depth estimation tool (VdET)
Identification of genes induced by BRCA1 in breast cancer cells
Cataloged from PDF version of article.Inherited mutations of the BRCA1 gene predispose to breast, ovarian, and other cancers. The role of the BRCA1 gene in the maintenance of chromosomal integrity is linked to a number of biological properties of its protein product, including transcriptional regulation. In the present study, we have used suppression subtractive hybridisation (SSH) to identify genes induced by BRCA1 by comparing control MCF7 breast carcinoma cells (driver) with MCF7 cells ectopically expressing BRCA1 (tester) and generated a forward subtracted cDNA library. We screened 500 putative positive clones from this library. Two hundred and ten of these clones were positive by differential screening with forward and reverse subtracted probes and the 65 cDNA clones which showed more than fivefold increase were selected for sequencing analysis. We clustered 46 different genes that share high homology with sequences in the GenBank/EMBL databases. Among these, 30 were genes whose function had been previously identified while the remaining 16 clones were genes with,unknown functions. Of particular interest, BRCA1 gene induces the expression of genes encoding DNA repair proteins RAD21 and MSH2, ERBB2/HER2 interacting protein ERBIN, meningioma-associated protein MAC30, and a candidate ovarian tumour-suppressor OVCA1. Northern and Western blot analyses confirmed that the expression of these five genes are up-regulated following BRCA1 overexpression in MCF7 and UBR60-bcl2 cells. This is the first study reporting a set of BRCA1-induced genes in breast carcinoma cells by the SSH technique. We suggest that some known genes identified in this study may provide new insights into the tumour-suppressor function of BRCA1. (C) 2002 Elsevier Science (USA). All rights reserved
Application-Specific Heterogeneous Network-on-Chip Design
Cataloged from PDF version of article.As a result of increasing communication demands, application-specific and scalable Network-on-Chips (NoCs) have emerged to connect processing cores and subsystems in Multiprocessor System-on-Chips. A challenge in application-specific NoC design is to find the right balance among different tradeoffs, such as communication latency, power consumption and chip area. We propose a novel approach that generates latency-aware heterogeneous NoC topology. Experimental results show that our approach improves the total communication latency up to 27% with modest power consumption. © 2013 The Author 2013.
