Does Information and Communication Technology Sustain Economic Growth? The Underdeveloped and Developing Countries Case

This paper tests the impact of ICT on economic growth for underdeveloped and developing countries by using a panel dataset for the period of 1995-2006. We first develop the theory of the relationship between ICT and economic growth. We show that ICT-capital has a positive effect both on long-run and transitional income per capita, if it is considered as a factor of production. Next, we estimate a panel data set with 131 underdeveloped and developing countries under the assumption that ICT is one of the determining factors of economic growth. We find that ICT has positive and significant effect on economic growth even after the use of some control variables.ICT, economic growth, panel data, GMM

In this study, molecularly imprinted polymer membranes were synthesized for the recognition and adsorption of quercetin. For this, quercetin imprinted polymeric membranes [p(HEMA-MAH)] (Poly(2-hydroxyethyl methacrylate-co-N-methacryloly-l-histidinemethylester) were synthesized by UV polymerization technique using HEMA and MAH as monomers. Synthesized polymeric membranes were characterized with SEM, FTIR and swelling test. Characterized membranes were used for the direct adsorption of quercetin in a batch system. Quercetin adsorption conditions were optimized by using the quercetin imprinted polymeric membrane by altering the pH, temperature and initial quercetin concentration of the adsorption medium. Effect of adsorption time was also studied for up to 180 min. The optimum pH and temperature was determined between 4.0 and 45 degrees C. Maximum adsorbed amount of quercetin onto quercetin imprinted poly(HEMA-MAH) membrane was found to be as 299.6 mg/g membrane using the initial quercetin concentration of 2.0 mg/ml. Adsorbed quercetin was desorbed from the polymeric membranes with isopropyl alcohol with desorption yield of 98.3%. and repeated usability of the quercetin imprinted polymeric membranes was fallowed for 7 adsorption/desorption cycles. At the end of the 7(th) reuse, quercetin adsorption capacity of the quercetin imprinted poly(HEMA-MAH) membranes decreased only about 10%

Tourism and women empowerment: Empirical findings from past experience and predictions for the post-COVID era

Tourism industry is one of the major industries of today’s world and hence it is in the forefront of current national and international policies. Tourism is perceived as one of the fundamental engines of economic growth and development due to the fact that it has many contributions to the economy. Moreover, tourism has a dimension of women empowerment which is one of the critical issues of modern world. Hence, researchers and policymakers have begun to pay more attention to the issue of gender discrimination and tourism relationships. There are some direct linkages between tourism and women empowerment, and what is more is that it seems critical to analyse these relationships in order to form effective development policies. In this sense, this study aims to analyse the long-run relationships between tourism revenues and female labor force participation across different country groups and to develop predictions about post-COVID era. In this context, following a brief introduction, the first section is devoted to a literature review about relationships between tourism industry, women empowerment and COVID-19 pandemic. Then the second section is attributed to the empirical analyses. Lastly, the third section is devoted to current situation and future predictions about post-COVID era

Endogenous determination of FDI growth and economic growth: the OECD case

This paper tests the endogenous relationship between Foreign Direct Investment (FDI) growth and economic growth using a panel data set for 23 Organisation for Economic Co-operation and Development (OECD) countries for the period 1975-2004. In particular we estimate a two-equation simultaneous equation system with the Generalised Methods of Moments (GMM) that treat economic growth and FDI growth as endogenous variables. We find that FDI growth and economic growth are significant determinants of each other. We also find that export growth rate and human capital are statistically significant determinants of both FDI growth and economic growth. Our findings lead us to conclude that FDI growth and economic growth have an endogenous relationship.FDI growth; foreign direct investment; economic growth; panel data; generalised methods of moments; Organisation for Economic Cooperation and Development; OECD; two-equation simultaneous equations; endogenous variables; significant determinants; exports; human capital; statistics; endogenous relationships; public policy; governance.

Preparation and characterization of silanized poly(HEMA) nanoparticles for recognition of sugars

WOS: 000376136500010PubMed ID: 25465044In this study presented, p(HEMA) nanoparticles were synthesized by the emulsion polymerization technique and then activated by a silanization agent, 3-aminopropyltriethoxysilane (APTES). The APTES-functionalized p(HEMA) nanoparticles that were synthesized were characterized by studies using the Zetasizer, FTIR and SEM. The p(HEMA)-APTES nanoparticles were further modified with phenyl boronic acid (PBA), and these boronate affinity nanoparticles were used for the recognition of some sugars such as galactose, fructose and raffinose. The system parameters (temperature and initial sugar concentration) were optimized for maximum sugar adsorption. The maximum amount of galactose, fructose, and raffinose adsorbed were found to be 4334.5 mg/g; 4334.9 and 810.0 mg/g, respectively (at 25 degrees C, in a phosphate buffer of pH 7.0). Considering the results of this study, it can be concluded that these nanoparticles may be used as a new alternative for the specific recognition of sugar

Boronate affinity nanoparticles for nucleoside separation

WOS: 000368022400042PubMed ID: 25137488Boronate affinity systems have been recently used for the specific isolation of cis-diol group carrying biomolecules such as glycoproteins, nucleosides, carbohydrates. Nanosized materials have been extremely used for the biotechnological purposes due to their unique properties and their high surface areas. The objective of this presented work was to develop a new boronate affinity system for the nucleoside adsorption. For this purpose, poly(HEMA) nanoparticles were synthesized by using surfactant free emulsion polymerization technique and then functionalized with phenylboronic acid. Synthesized nanoparticles were characterized with FTIR, SEM, and Zeta size analysis. Nucleic acid adsorption experiments were repeated for different medium pH values, for various nucleosides concentrations, for different temperatures and ionic strengths, in order to determine the optimum adsorption conditions. In the light of these studies, it can be concluded that this boronate ligand carrying nanoparticles were very valuable for the separation of nucleosides
