Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2012

description: This research has been done to solve the relatively poor performance problem of different public companies and enhance economic growth of Ethiopian economy through public sector capacity building. Accordingly, this study examined the success of Ethiopian Airlines, its determinant factors as well as lessons that can be taken by other public companies from its experience. In doing that, descriptive as well as econometric analysis based on performance indicators and endogenous growth model are respectively used. The results of descriptive analysis indicate that Ethiopian Airlines is a successful enterprise. This is mainly because the airline is a profitable, with a culture of continuous improvement, paramount productivity growth, higher market share etc. In this regard, several factors have contributed for the success of the airline: its working standard, overall system, dedication of workforce, safety trend, best practice, current and recurrent trainings, formation history, state art technology, autonomous management, its market strategy, visionary leadership style etc. Similarly, the results of econometric analysis reveal that the major determinants for the growth/success of Ethiopian Airlines are physical capital accumulation and human capital creation. Therefore, it is the combination of the earlier qualitative determinants with both physical and human capital that has played a significant role for its success. Finally, based on the findings, government and different public enterprises can take the aforementioned success leading factors as a lesson. Provided that different public enterprises have different character of their own that they should apply everything based on the type of their business.
Extending the Nanbu Collision Algorithm to Non-Spitzer Systems and Application to Laser Heating and Damage

description: We have generalized the Nanbu collision algorithm to accommodate arbitrary collision rates, enabling accurate kinetic modeling of short range particle interactions in non-Spitzer systems. With this extension, we explore the effect of different collision models on the simulation of how ultra-intense lasers first begin to heat a target. The effect of collisions on plasma evolution is crucial for treating particle slowing, energy transport, and thermalization. The widely used Nanbu collision algorithm provides a fast and computationally efficient method to include the effects of collisions between charged particles in kinetic simulations without requiring that the particles already be in local thermal equilibrium. However, it is "hardwired" to use Spitzer collision rates appropriate for hot, relatively dilute plasmas. This restriction prevents the Nanbu collision algorithm from accurately describing the initial heating of a cold target, a key problem for the study of laser damage or the generation of the warm dense matter state. We describe our approach for modifying the Nanbu collision algorithm and demonstrate the improved accuracy for copper targets.
title: Solute-solvent interactions in supercritical water: density-, and temperature-dependent effects on the Krichevskii parameter of different monovalent salts

description:
Reliable models describing chemical equilibria of aqueous fluids at high temperatures (T) and pressures (P) are crucial to several areas of the geoscience, ranging from problems in ore deposit geology to the use of geothermal energy systems.

Despite this importance, to date there is no model that can accurately predict the thermodynamic properties of supercritical aqueous fluids at and near the critical point (CP) of water.

This is due to the strongly divergent nature of certain thermodynamic properties of solutes, such as partial molar volumes (PMV), whose derivatives approach infinity at the critical point and are therefore difficult to constrain experimentally. Therefore, it is important to find ways to avoid direct treatment of anomalously behaving solution properties under CP conditions.

In this context, the Krichevskii parameter AKr is considered a promising key variable, which is closely related to the PMV of a solute and is known to describe a smooth function even in the vicinity of the CP of water. In an effort to better understand the behavior of AKr of different monovalent salts, we perform classical molecular dynamics (MD) simulations of supercritical aqueous solutions in a wide range of temperatures and densities. We describe the effect of solute type, T and water density on the behavior of AKr and draw connections to the molecular structure of water under the respective conditions. Our observations contribute to a deeper understanding of solute-solvent interactions under supercritical conditions and serve as part of a molecular-level guide for the development of future thermodynamic models.
Impact of Economic Globalization on Human Development in Sub-Saharan African: A Dynamic Panel Data Analysis

description: Participation in the existed global economic integration is an inevitable process because it brings additional positive force for the acceleration of economic growth, and ensuring sustainable development, particularly for resource-scarce developing countries like Sub- Saharan Africa., But there will be a need to regulate the level and value of the integration to maximize the benefits and reduce the costs associated with it. The debate about economic development has taken on a new turn since recent years and start thinking beyond per capita gross national product as the measure of a country's development performance, instead the human development index challenged purely economic measures of national achievement and helped lay the conceptual foundation for the UN's MDGs, calling for consistent global tracking of progress in health, education and overall living standards. To this effect, using a panel data on 39 Sub-Saharan African countries from 1990 to 2009, this study explores the potential contribution of economic globalization for the achievement of human development in SSA. The study uses HDI as a dependent variable and the inflow of investment, GDP Per Capita and trade openness as independent variables. To test the sensitivity of the results, I employ the dynamic panel data method based on System GMM to verify findings. The estimation result suggests that both greater GDP Per Capita and the inflow of foreign investment are positively and significantly contribute to the growth of human development index and then to the progress of those human development components of MDGs. But, the study also confirms outward trade policy has no a direct impact in country's effort to improve the welfare development of their nation in the region. Moreover, the study recommends SSA countries should focus on domestic and foreign investment policies that encourage job creation, skill and technology transfers, strengthen the quality and accessibility of both health and education sectors

description: Kiwi extract (KE) including different components such as quercetin, vitamins C and E, and actinides has been known as a debridement agent for burn wounds. In this study, electrospun poly(ɛ-caprolactone)/cellulose acetate blend nanofibers incorporating KE (PCL/CA/KE) were prepared and their performance was evaluated for healing acceleration of burn wounds. The physicochemical characterization of PCL/CA/KE nanofibers showed an average diameter of ∼420 nm, porosity of 70%, water contact angle of 61°, and water uptake of ∼220%. Moreover, the continuous release trend of KE from PCL/CA blend nanofibers happened during 24 h and the release mechanism was governed by the Fickian diffusion. Besides the cytocompatibility of PCL/CA/KE nanofibers, their in vivo experiments revealed that the bioactive wound dressing based on the sample has higher wound closure compared to KE after 21 days. Histopathology of wounds dressed by PCL/CA/KE nanofibers indicated epidermal formation along with a fully extended layer. Eventually, the obtained results confirmed that the PCL/CA/KE nanofibrous sample was a promising wound dressing for burn wound healing.
Comment on "Atmospheric ionization by high-fluence, hard spectrum solar proton events and their probable appearance in the ice core archive" by A.L. Melott et al

description: Melott et al. [2016] suggest that individual solar proton events (SPEs) are detectable as nitrate ion spikes in ice cores. They use the high fluence, high energy (hard spectrum) SPE of 23 February 1956 to calculate an enhancement of HNO3 from the surface to 46 km that is equivalent to a ~120 ng cm-2 nitrate ion spike observed in the GISP2H ice core. The Melott et al. [2016] approach is fundamentally flawed, since it considers only the absolute column burden of SPE-produced nitrate and not the pre-existing nitrate in the stratosphere. Modeling studies supported by extensive observations [Duderstadt et al., 2014, 2016, and this comment] show background HNO3 in the lower and middle stratosphere equivalent to 2000 to 3000 ng cm-2 nitrate. These high levels of background nitrate must also be included when estimating SPE enhancements to the deposition of nitrate ions that might eventually be preserved in an ice core. The 1956 SPE results in less than a 5% increase in the column burden of atmospheric HNO3, not large enough to explain the nitrate spike seen in the GISP2H ice core. Even extreme SPE enhancements cannot explain nitrate peaks (typically hundreds of percent increases) observed in the ice record [Duderstadt et al., 2016]. Realistic mechanisms linking nitrate ions in ice cores to SPEs have not been established. It is time to move the search for indicators of SPEs away from nitrate ions: Nitrate ions cannot be used as proxies for individual SPEs in the ice core record.

What Determine Child Labor In Rural Ethiopia? (Panel Data Analysis)

Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Despite the detrimental effects of child labor have on the nation and the availabilities of several written rights of children in the constitution, child labor is still a wide spread and sever problem in rural Ethiopia. The objective of this research was to identify the socio-economic factors affecting child labor in rural Ethiopia. Random effects model using Generalized Least Squares (GLS) estimator was used to estimate the determinants of child labor. The micro and balanced panel data from the Ethiopian Rural Household Survey of the Economics department of the Addis Ababa University was employed in the analysis. The findings of the result supported the hypothesis that the child being farm worker and domestic worker, age of child, dependency ratio, the presence of infant in the house hold, household size, number of plots of land, consumption expenditure, distance from high schools were positively related to child labor. The region where the household resides also had an effect on child labor incidence. However, first work starting age, enrollment status of the child, age square of child and the number of male members have had significant but negative effect on child labor. In our study we found that there was gender and age bias in child labor incidence. From policy perspective, enforcing the family planning policy, provision of productive but labor saving assets, investment in education infrastructure, enforcing the ILO convention of minimum age for employment and instituting saving and credit institutions like eqqub and bank should deserve essential place in mitigating child labor .However, we need all rounded but gender, age, type of activities and region specific policies rather than "one size fits all" policy

description: The electronic structure of FeSe, the simplest iron based superconductor (Fe-SC), conceals a potential of dramatic increase of Tc that realizes under pressure or in a single layer film. This is also the system where nematicity, the phenomenon of a keen current interest, is most easy to study since it is not accompanied by the antiferomagnetic transition like in all other Fe-SC's. Here we overview recent experimental data on electronic structure of FeSe-based superconductors: isovalently doped crystals, intercalates, and single layer films, trying to clarify its topology and possible relation of this topology to superconductivity. We argue that the marked differences between the experimental and calculated band structures for all FeSe compounds can be described by a hoping selective renormalization model for a spin/orbital correlated state that may naturally explain both the evolution of the band structure with temperature and nematicity.

Hydrodynamical Coupling of Mass and Momentum in Multiphase Galactic Winds

Publisher: name: arXiv
Year: 2016
Subjects: subject: Astrophysics of Galaxies (astro-ph.GA)

description: Using a set of high resolution hydrodynamical simulations run with the Cholla code, we investigate how mass and momentum couple to the multiphase components of galactic winds. The simulations model the interaction between a hot wind driven by supernova explosions and a cooler, denser cloud of interstellar or circumgalactic media. By resolving scales of $Δx<0.1$ pc over $>100$ pc distances our calculations capture how the cloud disruption leads to a distribution of densities and temperatures in the resulting multiphase outflow, and quantify the mass and momentum associated with each phase. We find the multiphase wind contains comparable mass and momenta in phases over a wide range of densities and temperatures extending from the hot wind ($n \approx 10^{-2.5}$ $\mathrm{cm}^{-3}$, $T \approx 10^{6.5}$ K) to the coldest components ($n \approx 10^2$ $\mathrm{cm}^{-3}$, $T \approx 10^2$ K). We further find that the momentum distributes roughly in proportion to the mass in each phase, and the mass-loading of the hot phase by the destruction of cold, dense material is an efficient process. These results provide new insight into the physical origin of observed multiphase galactic outflows, and inform galaxy formation models that include coarser treatments of galactic winds. Our results confirm that cool gas observed in outflows at large distances from the galaxy ($\gtrsim1$kpc) likely does not originate through the entrainment of cold material near the central starburst.

description:
This presentation focuses on technical ceramics from various early Modern dumping contexts ranging from a well to latrine and surface fills within in the former city walls of Mannheim.

Additionally domestic glazed earthenware from a latrine fill were analysed that exhibited alterations to surface texture and colour or were covered with residues which were hypothesised to be affiliated to chymistry practices during this period.

The analytics were performed using a combination of chemical analysis via micro-X-Ray Fluorescence (µXRF) and/or Scanning Electron Microscope with Energy Dispersive Spectroscopy (SEM-EDS) as well as mineralogical analysis via micro-X-Ray diffraction (µ-XRD2), to determine the nature of pyrotechnological processes as well as the source of alterations and residues. Technical ceramics were further analysed via ceramic petrography to define their technological characteristics, including refractoriness and the pyrotechnological processes in which they were used.

Preliminary results suggest that while most of the glaze alterations seem to be caused by weathering processes during burial, some may be related to misfiring or refiring processes. Jarosite was identified at the surface of some domestic ceramic fragments and might be connected to separation processes in precious metal working but could be formed by weathering as well. However, iron and alkaline rich slags with specks of precious metal alloys further strengthen this interpretation. Other crucibles contained slags indicating pale ore assaying.
The Determinants of Modern Agricultural Inputs Adoption and Their Productivity in Ethiopia (The Case of Amhara and Tigray Regions)
Creators: name: Gebru, Ashenafi
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2006

description: The role of the agricultural sector in terms of its contribution to the Ethiopian economy is very immense. Further, the success and failure of the Ethiopian economy is highly correlated to the performance of this sector. But, still now, the sector is operated by traditional means of production and well known for its backwardness. Hence, to accelerate the sector's growth and increase its contribution to the overall economic growth and securing the food self sufficiency objective of the country, the application of modern inputs in the sector plays a great role. This paper mainly aims at identifying those factors which significantly contribute to the adoption decision of modern agricultural inputs by the farmers and their productivity. To this end, the data collected by EDRI in 2001/2002 is used. In order to identify the significant factors contributing to the farmers' adoption decision, the logit model is used. The factors contributing to productivity are identified using the Cobb- Douglas production function model. It is found that farmers endowed with better resources are better adopters in both Amhara and Tigray regions. The distance of input delivery institutions from the household, extension contact of the farmers and agro-ecological conditions are also major determinants of the adoption decision in both regions. Further, the socioeconomic status of the farmers and the education levels of the household head's are significant in Amhara regions. The impact of land size, the ownership of oxen and agro-ecological conditions to the productivities of farmers in both regions are significant. Further, other sources of income than agriculture, access to credit and ownership of radio are significant determinants of productivity in Tigray. But in the case of Amhara region, whether the farmer is adopter or not, whether there is sick family member in the household and the socio-economic status affect the productivity of farmers.

description: We present a three-dimensional (3D) study of common envelope events (CEEs) to provide a foundation for future one-dimensional (1D) methods to model the self-regulated phase of a CEE. The considered CEEs with a low-mass red giant end with one of three different outcomes -- merger, slow spiral-in, or prompt formation of a binary. To understand which physical processes determine different outcomes, and to evaluate how well 1D simulations model the self-regulated phase of a CEE, we introduce tools that map our 3D models to 1D profiles. We discuss the differences in the angular momentum and energy redistribution in 1D and 3D codes. We identified four types of ejection processes: the pre-plunge-in ejection, the outflow during the plunge-in, the outflow driven by recombination, and the ejection triggered by a contraction of the circumbinary envelope. Significant mass is lost in all cases, including the mergers. Therefore a self-regulated spiral-in can start only with a strongly reduced envelope mass. We derive the condition to start a recombination outflow, which can proceed either as a runaway or a stationary outflow. We show that the way the energy of the inspiraling companion is added to the envelope in 1D studies intensifies the envelope's entropy increase, alters the start of the recombination outflow, and leads to different outcomes in 1D and 3D studies. The steady recombination outflow may dispel most of the envelope in all slow spiral-in cases, making the existence of a long-term self-regulated phase debatable, at least for low-mass giant donors.

An empirical investigation of inter sectoral linkage in Ethiopia: a co-integrated VECM approach
Creators: name: Fasikaw, Adimasu
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2018

description: The main objective of this paper was to examine the long run nature and direction of inter sectoral linkages between agriculture, industry and service sectors with a view to identifying the main growth stimulating sector in the economy in the case of Ethiopia. The study used time series data for the period between 1974 and 2016. The researcher estimated an econometric model that incorporates the linkages among the sectors using a Vector Error Correction Model. Johansen's co-integration test confirms the existence of one long-run relationship among the variables. Vector Error Correction Model (VECM) results indicated a strong long-run relationship between industry and service sector and also between agriculture and service sector. On the other hand, there is only a statistically significant association between industry and service sectors in the short run. Short run Granger causality test result also supports this outcome showing a strong unidirectional causality from industry to service sector. On the other hand, results of variance decomposition analysis and impulse response function suggest that service sector plays an important role in determining the growth of both the agriculture and industry through its positive innovative impact in medium to long-term perspective. The result of this paper suggests that government should be considered this directions and magnitudes of the inter-sectoral linkages before they set a policy and should focus on economic policies that promote multidimensional inter sectoral linkage.

description: In this paper, some statistical distributions of wide pairs included in Double Star Catalogue are investigated. Frequency distributions and testing hypothesis are derived for some basic parameters of visual binaries. The results reached indicate that, it was found that the magnitude difference is distributed exponentially, which means that the majority of the component of the selected systems is of the same spectral type. The distribution of the mass ratios is concentrated about 0.7 which agree with Salpeter mass function. The distribution of the linear separation appears to be exponentially, which contradict with previous studies for close binaries.

The Long run Impact of Government Domestic Borrowing on Bank Credit to the Private Sector in Ethiopia
Creators: name: Endashaw, Megersa
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2014

description: Motivated by the heavy government reliance on domestic banks credit over the last couple of years in Ethiopia, the current paper attempted to empirically test its longrun impact on private sector credit employing the tools of cointegrated VAR model. The paper used quarterly data ranging from QI 1999 to QIV 2013 E.F.Y. to chiefly explore the longrun impact of both bank credit financed government deficit and bank credit directed to the public sector on private sector credit. Arguing against the classical "interest rate transmission channel" for the Ethiopian case, and hence introducing the channel of credit i.e. availability of credit, the paper generated some important findings. Bank credit directed to the public sector reports a significant and positive longrun effect on private sector credit over the period of study. As such a 1 birr permanent increase in bank credit to the public sector is associated with a 0.40 cents growth in bank credit to the private sector supporting the crowding in effect hypothesis. The effect is stronger when we account for endogeneity of gross domestic product and bank credit financed government deficit (about 0.47 cents growth in bank credit to the private sector). Gross domestic product and bank credit financed government fiscal deficit coefficients, on the other hand, reports a positive but insignificant longrun effect on private sector credit.

description: A subcell technique for calculation of optical properties of graphene with the finite-difference time-domain (FDTD) method is presented. The technique takes into account the surface conductivity of graphene which allows the correct calculation of its dispersive response for arbitrarily polarized incident waves interacting with the graphene.The developed technique is verified for a planar graphene sheet configuration against the exact analytical solution. Based on the same test case scenario, we also show that the subcell technique demonstrates a superior accuracy and numerical efficiency with respect to the widely used thin-film FDTD approach for modeling graphene. We further apply our technique to the simulations of a graphene metamaterial containing periodically spaced graphene strips (graphene strip-grating) and demonstrate good agreement with the available theoretical results.

description: Topological Insulator-based devices can transport electrons/photons at the surfaces of materials without any back reflections, even in the presence of obstacles. Topological properties have recently been studied using non-reciprocal materials such as gyromagnetics or using bianisotropy. However, these effects usually saturate at optical frequencies and limit our ability to scale down devices. In order to implement topological devices that we introduce in this paper for the terahertz range, we show that semiconductors can be utilized via their cyclotron resonance in combination with small magnetic fields. We propose novel terahertz operating devices such as the topological tunable power splitter and the topological circulator. This work opens new perspectives in the design of terahertz integrated devices and circuits with high functionality.

The Poverty Implication of Trade Liberalization in Sub-Saharan Africa Region: A Dynamic Panel General Method of Moments Analysis
Creators: name: Bekele, Jali
Publisher: name: National Academic Digital Repository of Ethiopia
Year: 2007

description: This thesis examines the poverty implication of trade liberalisation through its potential nexus with overall income growth and distribution. Combining results from OLS and Dynamic Panel GMM techniques due to Arellano-Bond (1991) and Blundell-Bond (1998) employed, some evidence is found from recent data that trade liberalisation is poverty reducing in SSA. Specifically, the OLS results show that the distributional consequences of trade liberalsiation are small and not significantly different from zero. However, openness to trade contributes to higher inequality in the region's resource rich countries. Additional results obtained from the same regression include that the poor's income is closely related with overall average income with an elasticity coefficient of around 0.8, and inflation is related with higher inequality. Thus, although the poor's income is closely related with overall income growth, income inequality will be rising over time which could be compounded by inflation. After accounting for most of the factors relevant in determining income growth, the growth impact of trade liberalisation was also examined. The principal finding in this is that trade liberalisation in SSA positively affects income growth. Combined, the findings suggest that trade liberalisation must have played a role in the recent decline in the region's poverty through its relation with income growth. Besides, although the structure of production in African economies is positive but not statistically different from zero, its significance could be disguised by the continued commodity demand boom African economies currently enjoy. However, the current policy on trade in SSA may not be adequate. First, openness in resource rich countries in region is associated with increasing income inequality. Secondly, the poor's income is less than unitary elastic to overall income changes that income inequality in the region will be increasing with growth overtime. Thus, complementary measures to tackle the growing tendency for inequality overtime and encouraging other growth drivers may be necessary.

description: Magnetic fields permeate the Universe on all scales and play a key role during star formation. We study the evolution of magnetic fields around a massive metal-free (Population III) star at $z \sim 15$ during the growth of its HII region and subsequent supernova explosion by conducting three cosmological magnetohydrodynamic simulations with radiation transport. Given the theoretical uncertainty and weak observational constraints of magnetic fields in the early universe, we initialize the simulations with identical initial conditions only varying the seed field strength. We find that magnetic fields grow as $ρ^{2/3}$ during the gravitational collapse preceding star formation, as expected from ideal spherical collapse models. Massive Population III stars can expel a majority of the gas from the host halo through radiative feedback, and we find that the magnetic fields are not amplified above the spherical collapse scaling relation during this phase. However, afterwards when its supernova remnant can radiatively cool and fragment, the turbulent velocity field in and around the shell causes the magnetic field to be significantly amplified on average by $\sim$100 in the shell and up to 6 orders of magnitude behind the reverse shock. Within the shell, field strengths are on the order of a few nG at a number density of 1 cm$^{-3}$. We show that this growth is primarily caused by small-scale dynamo action in the remnant. These strengthened fields will propagate into the first generations of galaxies, possibly affecting the nature of their star formation.

description: Dirac and Weyl semimetals form an ideal platform for testing ideas developed in high energy physics to describe massless relativistic particles. One such quintessentially field-theoretic idea of chiral anomaly already resulted in the prediction and subsequent observation of the pronounced negative magnetoresistance in these novel materials for parallel electric and magnetic fields. Here we predict that the chiral anomaly occurs - and has experimentally observable consequences - when real electromagnetic fields E and B are replaced by strain-induced pseudo-electromagnetic fields e and b. For example, a uniform pseudomagnetic field b is generated when a Weyl semimetal nanowire is put under torsion. In accord with the chiral anomaly equation we predict a negative contribution to the wire resistance proportional to the square of the torsion strength. Remarkably, left and right moving chiral modes are then spatially segregated to the bulk and surface of the wire forming a "topological coaxial cable". This produces hydrodynamic flow with potentially very long relaxation time. Another effect we predict is the ultrasonic attenuation and electromagnetic emission due to a time periodic mechanical deformation causing pseudoelectric field e. These novel manifestations of the chiral anomaly are most striking in the semimetals with a single pair of Weyl nodes but also occur in Dirac semimetals such as Cd3As2 and Na3Bi and Weyl semimetals with unbroken time reversal symmetry.

description: Shibata & Yokoyama (1999, 2002) proposed a method of estimating the coronal magnetic field strengths ($B$) and magnetic loop lengths ($L$) of solar and stellar flares, on the basis of magnetohydrodynamic simulations of the magnetic reconnection model. Using the scaling law provided by Shibata & Yokoyama (1999, 2002), $B$ and $L$ are obtained as functions of the emission measure ($EM=n^2L^3$) and temperature ($T$) at the flare peak. Here, $n$ is the coronal electron density of the flares. This scaling law enables the estimation of $B$ and $L$ for unresolved stellar flares from the observable physical quantities $EM$ and $T$, which is helpful for studying stellar surface activities. To apply this scaling law to stellar flares, we discuss its validity for spatially resolved solar flares. $EM$ and $T$ were calculated from GOES soft X-ray flux data, and $B$ and $L$ are theoretically estimated using the scaling law. For the same flare events, $B$ and $L$ were also observationally estimated with images taken by Solar Dynamics Observatory (SDO)/ Helioseismic and Magnetic Imager (HMI) Magnetogram and Atmospheric Imaging Assembly (AIA) 94Å pass band. As expected, a positive correlation was found between the theoretically and observationally estimated values. We interpret this result as indirect evidence that flares are caused by magnetic reconnection. Moreover, this analysis makes us confident in the validity of applying this scaling law to stellar flares as well as solar flares.

Fermi's Paradox Is a Daunting Problem---Under Whatever Label

description: Gray (2015) argued that the Fermi paradox (FP) is a misnomer, and it is not a valid paradox. Gray also speculated that the argument was misattributed to Fermi, whose lunchtime remarks did not pertain to the existence of extraterrestrial intelligence, but to the feasibility of interstellar travel. Instead, the paradox is ascribed to Hart and Tipler, and it is further suggested that the paradox is not a real problem or research subject and should not be used in debates about SETI projects. The arguments given are unpersuasive, ahistorical, and, in at least one instance, clearly hinge on literalistic and uncharitable reading of evidence. Instead, I argue the following three points: (i) Contrary to Gray's assertion, the historical issue of naming of ideas or concepts is completely divorced from their epistemic status. (ii) FP is easily and smoothly generalized into the Great Silence paradox, so it makes no sense either theoretically or empirically to separate the two. (iii) In sharp contrast to the main implication of Gray's paper, FP has become more aggravated lately due to advances in astrobiology.
