description: An eigenmode projection technique (EPT) is developed and employed to solve problems of electromagnetic resonance in closed cavities and scattering from discontinuities in guided-wave structures. The EPT invokes the eigenmodes of a canonical predefined cavity in the solution procedure and uses the expansion of these eigenmodes to solve Maxwell's equations, in conjunction with a convenient choice of port boundary conditions. For closed cavities, resonance frequencies of arbitrary-shaped cavities are accurately determined with a robust and efficient separation method of spurious modes. For waveguide scattering problems, the EPT is combined with the generalized scattering matrix approach to solve problems involving waveguide discontinuities with arbitrary dielectric profiles. Convergence studies show stable solutions for a relatively small number of expansion modes, and the proposed method shows great robustness over conventional solvers in analyzing electromagnetic problems with inhomogeneous materials.

The Impact of Real Effective Exchange Rate on The Economic Growth of Ethiopia
Creators: name: Baylie, Fentahun
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2011

description: This study analyzes the impact of real effective exchange rate on the Ethiopian economy using annual time series data for the period 1970-2009. With the help of cointegration and vector error correction analysis, the impact of real effective exchange rate on real gross domestic product growth was assessed in the long-run as well as in the short-run. The study found that the impact of real effective exchange rate on economic growth works through the aggregate demand channel in the short-run and the aggregate supply channel in the long-run i.e. decrease/depreciation in the value of the domestic currency promotes economic growth only in the short-run. In the long-run, it discourages economic growth. The study also found that the government, through its spending, may play a key role in bringing about economic growth in Ethiopia. Government expenditure is found to be equally statistically significant to real effective exchange rate in explaining economic growth in Ethiopia. Other variables like real interest rate and real exchange rate premium are also found to be statistically significant with the expected sign in explaining economic growth in the long-run. The study confirms that the country is on the right truck to go for a long-term economic growth as the [appreciation of] real effective exchange rate and [increase in] public expenditure are the most important tools of economic growth in the hand of the government. With the use of at least these two tools, the government may play a key role in transforming the agrarian economy. Key words: Real effective exchange rate, economic growth.

description: We study the multi-scale temporal correlations and causality connections between the New York Stock Exchange (NYSE) and Bombay Stock Exchange (BSE) monthly average closing price indexes for a period of 300 months, encompassing the time period of the liberalisation of the Indian economy and its gradual global exposure. In multi-scale analysis; clearly identifiable 1, 2 and 3 year non-stationary periodic modulations in NYSE and BSE have been observed, with NYSE commensurating changes in BSE at 3 years scale. Interestingly, at one year time scale, the two exchanges are phase locked only during the turbulent times, while at the scale of three year, in-phase nature is observed for a much longer time frame. The two year time period, having characteristics of both one and three year variations, acts as the transition regime. The normalised NYSE's stock value is found to Granger cause those of BSE, with a time lag of 9 months. Surprisingly, observed Granger causality of high frequency variations reveals BSE behaviour getting reflected in the NYSE index fluctuations, after a smaller time lag. This Janus faced relationship, shows that smaller stock exchanges may provide a natural setting for simulating market fluctuations of much bigger exchanges. This possibly arises due to the fact that high frequency fluctuations form an universal part of the financial time series, and are expected to exhibit similar characteristics in open market economies.

description:
Evidence for a miscibility gap between fluorapatite (FAp) and fluorbritholite-(Ce) (FBri) has been observed in various natural occurrences, inferred by significant compositional gaps between Ca + P (FAp) and REE + Si (FBri) chemical components.

This presentation delves into the observation of coupled exsolution microtextures of FAp in FBri and vice versa at the Rodeo de los Molles REE Prospect, in Argentina. The existence of a miscibility gap as a function of temperature between FAp and FBri was explored via a series of simple experiments performed at 500°, 600°, 700°, and 1100 °C and 200 MPa. A series of combinations involving synthetic CePO4 or FAp and CeF3 plus H2O and SiO2 and a series of reactants, i.e. Na2Si2O5, NaOH, NaF, CaF, KOH, and Ca(OH)2 was utilized. Experiments involving CePO4 and Na2Si2O5 and NaOH were the most reactive, while experiments involving KOH and Ca(OH)2 produced neither FBri nor FAp. This suggests that Na might play a major role in the formation of FBri.

      On a T vs FAp-FBri composition plot, the miscibility gap of natural samples is situated between FAp92FBri8 and FAp30FBri70 at T below 350 °C. At T above 350 °C the gap narrows down to FAp80FBri20 and FAp68FBri32. In the experiments, FBri-(Ce) shows a continuous compositional range from FAp78FBri22 to FAp28FBri72 for T = 500 °C, FAp76FBri24 to FAp52FBri48 for T = 600 °C and FAp80FBri20 to FAp60FBri40 for T = 700 °C. This indicates that there is no miscibility gap ≥ 500 °C between fluorapatite and fluorbritholite-(Ce).

Macroeconomic Impacts of External Assistance in Ethiopia
Creators: name: Siraj, Abeba
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2002

description: The thesis examines the impacts of external assistance on the economic performance of the country for the period 1960/61 –1999/00. The analysis makes use of the Johansen maximum likelihood estimation procedure estimating five equations to identify the independent effect of foreign assistance on investment and/or growth, saving, government tax revenue, government tax expenditure and real exchange rate. Accordingly, it is found that external assistance negatively affected the investment rate and hence the growth rate of the economy. The paper further investigates these unexpected negative relationships between foreign inflows and economic growth. The insignificant effect of external grant on domestic saving, negative impact of external grant on government consumption and the 'Dutch Disease' effect of both foreign grant and loan is responsible for the negative impact of foreign assistance on economic growth of the economy.

description: We extend our previous study of surface tension of ionic solutions and apply it to the case of acids (and salts) with strong ion-surface interactions. These ion-surface interactions yield a non-linear boundary condition with an effective surface charge due to adsorption of ions from the bulk onto the interface. The calculation is done using the loop-expansion technique, where the zero-loop (mean field) corresponds of the non-linear Poisson-Boltzmann equation. The surface tension is obtained analytically to one-loop order, where the mean-field contribution is a modification of the Poisson-Boltzmann surface tension, and the one-loop contribution gives a generalization of the Onsager-Samaras result. Our theory fits well a wide range of different acids and salts, and is in accord with the reverse Hofmeister series for acids.

title: Identifying Li-bearing phases by µEDXRF based automated mineralogy

Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)
Year: 2022

description:
The automated identification and quantification of Li-bearing phases in core samples and hand specimen has gained interest due to increasing industrial demand for lithium. Despite the fact, that Li cannot be directly detected by µEDXRF, the spectral signatures of a number of Li-bearing phases such as spodumene, lepidolite, amblygonite and others are characteristic enough to differentiate them from non-Li phases. By applying hyperspectral ENVI software and its spectral angle mapper (SAM) algorithm a supervised classification based on an endmember data bases can be used to image the phase distribution. SAM considers all ratios of available band based on total signal intensity per pixel per selected spectral region to offer a measure to compare an unknown pixel with all available endmembers of a database. A good knowledge of the paragenesis of each investigated system is key to limit ambiguities between Li phases, and non-Li phases carrying elements, such as H, Be, B, which cannot be detected either. This will be achieved by tailoring the endmember database according to these premises. Quantitative µEDXRF-based mineralogy is based on interpretation of chemical signatures, but shows some limitations regarding isochemical phases, isochemical mixtures at grain boundaries and sporadically strong diffraction signals of one or the other grain. Results which can be obtained are modal mineralogy, grain area size distribution, grain aspect ratio and sample and grain area chemistry.

description: b to s transitions are flavour-changing neutral current (FCNC) processes that play an important role in the search for physics beyond the Standard Model (SM). Contributions from virtual particles in the loop are predicted to deviate observables, such as the branching fraction, from their SM expectations. Using data from the BaBar experiment, we present the first search for the rare decay B to K tau tau. The BABAR results on the measurement of the angular asymmetries of B to Kstar l l, where l is an electron or muon, are also reported. In addition, using a time-dependent analysis of B to KS0 pi pi gamma, the mixing induced CP-asymmetry for the radiative FCNC decay, B to KS0 rho gamma, is measured, along with an amplitude analysis of the m (K pi) and m (K pi pi) spectrum.

description: We explore lepton-flavored electroweak baryogenesis, driven by CP-violation in leptonic Yukawa sector, using the $τ-μ$ system in the two Higgs doublet model as an example. This setup generically yields, together with the flavor-changing decay $h\to τμ$, a tree-level Jarlskog-invariant that can drive dynamical generation of baryon asymmetry during a first-order electroweak phase transition and results in CP-violating effect in the decay $h\to ττ$. We find that the observed baryon asymmetry can be generated in parameter space compatible with current experimental results for the decays $h\to τμ$, $h\to ττ$ and $τ\rightarrow μγ$, as well as the present bound on the electric dipole moment of the electron. The baryon asymmetry generated is intrinsically correlated with the CP-violating decay $h\to ττ$ and the flavor-changing decay $h\to τμ$, which thus may serve as "smoking guns" to test lepton-flavored electroweak baryogenesis.

Extensive photometry of the intermediate polar MU Cam: detection of a spin period change

Publisher: name: arXiv
Year: 2016
Subjects: subject: Solar and Stellar Astrophysics (astro-ph.SR)

description: Intermediate polars with known rates of spin period changes are not numerous because such tasks require measurements performed for a long time. To measure a spin period change, MU Cam is a good candidate because it has a spin oscillation with a large amplitude enabling measurements with high precision. Fortunately, in the past the spin period of MU Cam was measured with high precision. To measure the spin period anew, in 2014-2015 we performed extensive photometric observations of MU Cam, spanning a total duration of 208 h within 46 nights. We found that the spin, sideband and orbital periods are equal to 1187.16245+/-0.00047 s, 1276.3424+/-0.0022 s and 4.71942+/-0.00016 h, respectively. Comparing the measured spin period with the spin period of MU Cam in the past, we detected the spin period change with dP/dt=-(2.17+/-0.10) X 10^(-10). This rate of the spin period change was not stable and varied in a time scale of years. During four nights in 2014 April-May MU Cam was fainter than usual by 0.8 mag, and the amplitude of the sideband oscillation was five times larger, denoting significant fraction of disc-overflow accretion. The sideband oscillation showed a double-peaked pulse profile in the normal brightness state. When the star brightness was decreased by 0.8 mag, the sideband oscillation showed a single-peaked pulse profile. In contrast, the spin pulse, which was quasi-sinusoidal, remained remarkably stable both in profile and in amplitude. Moreover, the spin pulse was also remarkably stable in a time scale of years and even decades. MU Cam is of great interest because it represents a distinctive object with a large and unstable rate of the spin period change and exhibits a distinctive behaviour of the pulse profiles.

description:
This study proposes a new approach to investigate hydrocarbon generation and migration processes in petroleum source rocks under laboratory conditions. For the first time, programmed open-system pyrolysis using a Rock-Eval 6 instrument is applied on small, polished source rock plugs to induce changes in the type and distribution of solid bitumen, which is qualitatively investigated by means of organic petrography before and after treatments. This approach allows us to directly visualize the evidence of solid bitumen (SB) formation and distribution after the following treatments: (1) thermal extraction (300°C for 3 min), (2) chemical extraction of the surface using dichloromethane (DCM), and (3) artificial maturation up to 400 to 500°C. After each step, the surface of micro plugs was digitally scanned to allow a comparison of specific areas of interest before and after the treatments.

After thermal extraction, the volume of observed SB in the early- and moderately mature samples slightly increased, while most of the thermally mobilized bitumen from inside the plug was evaporated. The initial solid bitumen was not or hardly affected by thermal extraction at 300°C for 3 min, i.e. it was thermally stable at this temperature. After DCM treatment, SB in the early mature samples was almost completely dissolved. While some SB was dissolved in the moderately mature sample showing more mature and stable SB. After the artificial maturation, the volume of SB in early- as well as in moderately mature samples increased, indicating the presence of new SB due to bitumen migration from the plug.

description: The dynamics of an elliptical galaxy within a couple of effective radii can be probed effectively by stars. However, at larger distances planetary nebulae (PNe) replace stars as the tracer of the dynamics. Making use of the motion of PNe, Romanowsky et al. (2003) measured the dynamics of three luminous elliptical galaxies (NGC821, NGC3379, and NGC4494) at large distances from the galactic center. They found that little dark matter is needed up to 6 effective radii. Milgrom & Sanders (2003) showed that this result can be understood in the framework of MOdified Newtonian Dynamics (MOND). As more data are available in the past decade, we revisit this problem. We combine PNe data (up to 6{8 effective radii) and stellar data from SAURON of 7 elliptical galaxies, including those 3 galaxies in Romanowsky et al. (2003) with updated data and 4 other galaxies which have not been analyzed before. We conclude that the dynamics of these galaxies can be well explained by MOND.

Publisher: name: Deutsche Geologische Gesellschaft - Geologische Vereinigung e.V. (DGGV)

description:
Many accessory minerals, i.e., zircon, incorporate variable amounts of actinides, whose radioactive decay creates structural defects in their crystal structures. The increased susceptibility of radiation-damaged zircon to chemical alteration or aqueous leaching is of enormous importance as these processes may bias results of chemical and isotopic age determinations. Here, we present a new concept based on the luminescence emission of REE3+ that provides an estimate of the amorphous fraction from laser-induced PL measurements using state-of-the-art confocal spectrometers with spatial resolution in the µm-range. A careful investigation of PL spectra from self-irradiated zircon samples from Sri Lanka and Mt. Malosa (Malawi) reveal that the Dy3+-luminescence emission in zircon is basically a superposition of emissions from Dy ions in various, structurally different sites. The relative integrated area of a fitted model spectra from an amorphous reference sample in relation to the full integrated area of the obtained emission gives a good estimate of the amorphous fraction present in the probed sample volume. This opens up the possibility to investigate the accumulation of radiation damage in single crystals of zircon in great detail and give rise to direct comparison with damage accumulation in heavy ion irradiation experiments.

description: Inspired by a new stream of research that shows the significant role institutions play in determining economic performance, aid effectiveness and aid allocation, this study explores the relationship between aid, institutions and democracy. Using cross-country data for 91 developing countries it examines the determinants of aid and institutional quality and finds that selectivity is present and strong since the end of the cold war in aid allocation by donors. However it finds no significant positive incentive effects of this approach yet, but the pattern in the data shows democracies are relatively weak in responding to the incentive effect the new rule of aid allocation has on institutional reforms.
A constraint on the formation timescale of the young open cluster NGC 2264: Lithium abundance of pre-main sequence stars

description: The timescale of cluster formation is an essential parameter in order to understand the formation process of star clusters. Pre-main sequence (PMS) stars in nearby young open clusters reveal a large spread in brightness. If the spread were considered as a result of a real spread in age, the corresponding cluster formation timescale would be about 5 -- 20 Myr. Hence it could be interpreted that star formation in an open cluster is prolonged for up to a few tens of Myr. However, difficulties in reddening correction, observational errors, and systematic uncertainties introduced by imperfect evolutionary models for PMS stars, can result in an artificial age spread. Alternatively, we can utilize Li abundance as a relative age indicator of PMS star to determine the cluster formation timescale. The optical spectra of 134 PMS stars in NGC 2264 have been obtained with MMT/Hectochelle. The equivalent widths have been measured for 86 PMS stars with a detectable Li line (3500 < T_eff [K] <= 6500). Li abundance under the condition of local thermodynamic equilibrium (LTE) was derived using the conventional curve of growth method. After correction for non-LTE effects, we find that the initial Li abundance of NGC 2264 is A(Li) = 3.2 +/- 0.2. From the distribution of the Li abundances, the underlying age spread of the visible PMS stars is estimated to be about 3 -- 4 Myr and this, together with the presence of embedded populations in NGC 2264, suggests that the cluster formed on a timescale shorter than 5 Myr.

description:
The modern oceanographic setting off northern-central Chile is characterized by highly productive waters and an extensive Oxygen Minimum Zone (OMZ), both resultant from coastal upwelling induced by the Humboldt Current System. However, oscillations of upwelling and OMZ properties during the Neogene are still poorly understood. Here, we assess palaeoceanographic conditions based on benthic foraminifera assemblage data of marine sediments from the Bahía Inglesa Formation (Upper Miocene-Pliocene), recovered from the Quebrada Tiburón outcrop (27°42' S, 70°59' W). Quantitative paleoenvironmental analyses of benthic Foraminifera >250 µm from 6 samples are currently conducted. Preliminary results show shifts in both, the diversity and abundance of hyaline species over the studied interval. High abundances of planospiral (predominantly epifaunal) morphotypes in sandy, heavily bioturbated parts of the studied section alternate with diatom-rich sediments bearing predominantly serial (infaunal) taxa such as Bolivina aenariensis and Uvigerina peregrina/striata. The observed changes in assemblage composition imply significant changes in biological productivity, bottom-water oxygenation, and ultimately, coastal upwelling off Chile in the Neogene. Further refinements of the stratigraphic model for the studied section will clarify the timing of the here described preliminary observations of paleoenvironmental fluctuations. This study contributes to project A4 “Land‐ocean coupling between the Humboldt Current System and Atacama palaeoclimate in the Neogene” of CRC 1211 “Earth-evolution at the dry limit”.

description: We compare, in an extensive and systematic way, linear theory results obtained with the hybrid (ion-kinetic and electron-fluid), the gyrokinetic and the fully-kinetic plasma models. We present a test case with parameters that are relevant for solar wind turbulence at small scales, which is a topic now recognized to need a kinetic treatment, to a certain extent. We comment on the comparison of low-frequency single modes (Alfvén/ion-cyclotron, ion-acoustic, and fast modes) for a wide range of propagation angles, and on the overall spectral properties of the linear operators, for quasi-perpendicular propagation. The methodology and the results presented in this paper will be valuable when choosing which model should be used in regimes where the assumptions of each model are not trivially satisfied.

description: Unlike the standard cross-country growth regressions that focus on the long run average growth and hence mask episodes of high and low growth that most of these countries experience, this paper follows the recent literature and examine growth episodes in SSA countries. This new approach applied enable us identify years of growth accelerations and episodes which were sustained over the medium and long-term. More specifically, utilizing the Penn World Data Tables (version 6.2), the study follows the diagnostic or two-pronged strategy of Rodrik (2005a and 2005b), which focuses on the particular constraints that prevent a given country from growing faster. In the latter part, we analyze the impact of growth on income poverty and inequality in selected countries drawing on available household survey data published by the World Bank in its Global Poverty Monitoring Database. To establish correlation between growth episodes(all accelerations and sustained ones) and policy variables, institutional variables and geographic factors, we estimate alternative limited dependant variable models. The results show that variables affect these two growth episodes differently. While US interest rate(proxy of international interest rate shock), petroleum price shock, democratization, regime change, resource richness and government expenditure are important predictors of growth accelerations, positive terms-of-trade shock, growth rate of GDP deflator, economic liberalization, financial liberalization, ethnolinguistic factorization, resource endowment, and age dependency ratio determine the probability of sustained growth. The reform variables are not crucial for igniting growth. Rather, these variables are highly correlated with the timing of sustained growth. On the other hand, by constructing a panel of income, poverty and inequality measures for selected countries, we were able to analyze the impact of growth on poverty and inequality; and of inequality on poverty. The result implies that inequality does not change significantly over time in the set of countries analyzed and that growth in these countries is generally pro-poor. It also depict that these countries should sustainably grow by about 7 percent per annum to achieve the MDG of poverty alleviation.
title:  Piattaforme, mediazione e rappresentazione: regimi di visibilità e di verità nei dispositivi digitali

description: Scopo del contributo è la comprensione delle piattaforme digitali, la cui forma ha oramai contagiato la quasi totalità dello spazio del web, come dispositivi volti alla riproduzione di specifiche operazioni capitalistiche di profitto e controllo. Tale comprensione implica la demistificazione critica di una diffusa visione di internet che lo presenta come un ambiente trasparente e immediato, che permetterebbe una visione e un accesso all’informazione privi di ostacoli. Al contrario, la considerazione della piattaforma come dispositivo permette, attraverso la riattivazione del pensiero foucaultiano e deleuziano, di mostrare i regimi di visibilità e di enunciazione che essa dispone, di svelare i fondamenti epistemologici e lo specifico regime di verità che impone e di convertire così la trasparenza in opacità e l’immediatezza in iper-mediazione.

The aim of this contribution is understanding digital platforms, whose structure has now infected almost all the space of the web, as devices aimed at reproducing specific profit- and control-oriented capitalist operations. Such understanding implies the critical demystification of a widespread vision of internet that presents it as a transparent and immediate environment that grants a limitless vision and access to information. On the contrary, building on the intuitions of Foucault and Deleuze, the consideration of the platform as a dispositif allows to show the regimes of visibility and enunciation that it arranges, to reveal the epistemological basis and the specific regime of truth it imposes – as well as to convert transparency into opacity and immediacy into hyper-mediation.

description:
Little is known about the build-up of Mediterranean cold-water coral mounds at the scale of multiple interglacial-glacial cycles. This study concentrates on the long-term development of coral mounds within the East Melilla Coral Province (Southeast Alboran Sea) and exposes how the distribution of benthic foraminiferal assemblages can provide key palaeoenvironmental information about the long-term processes driving coral mound development. The multiproxy investigation of core MD13-3462G reveals that mound build-up took place during both interglacial and glacial periods, at average aggradation rates ranging between 1 and 10 cm.kyr-1. These observations imply that corals never thrived but rather developed under stressful environmental conditions. High abundances of infaunal benthic foraminifera (Bulimina marginata, Bulimina striata and Uvigerina mediterranea) suggest that weak seafloor oxygenation associated to important terrestrial organic matter input characterized interglacial periods, whilst the dominance of large epibenthic species (Discanomalina coronata and Lobatula lobatula) and Miliolids is probably linked to stronger Levantine Intermediate Water circulation and fresher organic matter input during glacial periods. Glacial periods are further characterized by peak abundances of the erect branching bryozoan species Buskea dichotoma. Moreover, planktonic (Globigerina bulloides) and benthic (Lobatula lobatula) δ18O records show typical interglacial-glacial variations during the last two interglacial-glacial cycles. This is in contrast with δ18O records generally recovered from coral mounds in the Atlantic and implies that the northern part of Brittlestar Ridge I experienced reduced albeit relatively continuous accretion.
Wilson lines, Grassmannians and Gauge Invariant Off-shell Amplitudes in N=4 SYM

description: In this paper we consider tree-level gauge invariant off-shell amplitudes (Wilson line form factors) in $\mathcal{N}=4$ SYM. For the off-shell amplitudes with one leg off-shell we present a conjecture for their Grassmannian integral representation in spinor helicity, twistor and momentum twistor parameterizations. The presented conjecture is successfully checked against BCFW results for MHV$_n$, NMHV$_4$ and NMHV$_5$ off-shell amplitudes. We have also verified that our Grassmannian integral representation correctly reproduces soft (on-shell) limit for the off-shell gluon momentum. It is shown that the (deformed) off-shell amplitude expressions could be also obtained using quantum inverse scattering method for auxiliary $gl(4|4)$ super spin chain.

description: ABSTRACT
 The reduction of non-sugar compounds content in all intermediate and by-products of the sugar industry, especially molasses, shifts the production towards sugar yield increase and also facilitates betaine recovery. In this respect, the application of possible non-sugar compounds adsorbents is being intensively explored. The presented study investigates the application of sugar beet pulp and sodium bentonite as adsorbents in sugar beet molasses purification treatment. Potential reduction of non-sugar compounds content in molasses was monitored through measurements of molasses colour and turbidity.
 The experiments were conducted according to the Box-Behnken experimental design and the effects of independent variables: pH (3−7), adsorbent concentration (3−7 g/L) and molasses dry substance (30−50°Bx) on the sugar beet molasses colour and turbidity were determined by response surface methodology. Applied temperature (60°C) and mixing speed were kept constant throughout the experiments.
 The most pronounced impact on molasses colour and turbidity was expressed by pH, regardless of adsorbent used. Low pH treatments improved molasses colour reduction while opposite effect was observed regarding turbidity reduction. More efficient molasses colour reduction was noticed upon sodium bentonite addition compared to the sugar beet pulp. Conversely, greater molasses turbidity reduction was observed upon sugar beet pulp application.

description: Internet use, especially in developing countries, has expanded rapidly in recent years. Even in light of this, penetration rates differ markedly between developed and developing countries and across developing countries. To identify the determinants of Internet penetration in low income countries of SSA, the study examines panel data for 25 SSA countries over the year 2009-2013 periods using Arellano and Bover (1995) dynamic panel data estimation technique. The study find evidence indicating that network externalities, GDP percapita, mobile cellular subscription, ICT goods import from developed countries, and urbanization are associated with high internet penetration rates. Estimates from Arellano Bover (1995) reveal that the main factor responsible for low rates of internet penetration is unemployment. Hence, policy measures geared towards improving the countries investment in telecommunication sector, expanding productive employment should be given due emphasis if the economy is to benefit from internet use.
