Financial Economics

description: An inclusive financial system has been widely recognized by most policy makers around the world and is becoming a priority in policy making globally. An inclusive financial system is one that creates economic opportunities along with ensuring equal access to them. Agriculture, on the other hand, continues to be renowned as an engine for growth in many poor economies and thus the importance of financial inclusion for agricultural development cannot be ignored. This research work sought to examine the relationship between financial inclusion and agricultural development in Southern African Development Community (SADC). The main objective of the study was to establish the relationship between financial inclusion and agricultural development in the SADC region. The study determined the level of financial inclusion in the SADC region by calculating the index of financial inclusion. The index gathers information from the World Bank G20 financial inclusion indicators using methodological inputs from the research works of Sarma (2008). An agricultural development index was also calculated to determine the level of agricultural development in the SADC region using secondary data from the African Development Bank, an open Africa database. To determine the relationship between financial inclusion and agricultural development, secondary data were extracted from the African Development Bank’s open data for Africa database. These data were analyzed using descriptive statistics, correlation and regression analysis. Excel software was used to transform the variables into a format suitable for analysis, after which STATA version vi 14 was used to provide the basis of analysis and the findings of the study. For the basis of analysis and because of the unavailability of data on agricultural development measured as a single number, the Agricultural Production Index (API) was used as a proxy for agricultural development. A period of ten years was covered, from 2005 to 2014, for all 15 SADC countries and the panel fixed effects regression model was confirmed by the Hausman test as appropriate for the study. The regression analysis established that the usage of financial services (amount of bank loans as a proportion of total deposits) has a statistically significant relationship with agricultural development. The number of bank branches (per 1000 km2 ) and ATMs (per 100 000 people) have a positive relationship with agricultural development and thus an increase in access to financial services is associated with an increase in agricultural development in the SADC region. Therefore, this study confirmed the hypothesis that agricultural development and financial inclusion are positively related. Hence, high financial inclusion is associated with high agricultural development in the SADC region.
The effects of outdated data and outliers on Kenya's 2019 Global Food Security Index score and rank

description: While composite indicators are considered robust in measuring food security, outdated data and outliers challenge their reliability. Outdated data can occur when national databases are not frequently updated while outliers are extremely small or large values in a study. Outdated data could be referred to as missing current data in composite indicators used for annual benchmarking exercises, where data must be frequently updated. Besides hindering useful information within an index, outdated data could also result in outliers in a database, especially when the outdated or missing current data are imputed by estimation. Studies that have assessed the robustness of composite indicators highlight that outdated data and outliers could bias results, thereby hindering an index's reliability. However, depending on the methods used when constructing a composite indicator, some methods can be considered robust even with the presence of outliers in a data point. Outdated national data could hinder countries from tracking the progress of international, national or regional commitments, such as the Sustainable Development Goals, while outliers could act as an unintended benchmark. This study assessed the impacts of outdated data and outliers on Kenya's scores and rankings in the Global Food Security Index (GFSI). The study objective was achieved by assessing Kenya's performance in the 2019 GFSI result before and after removing outliers from the GFSI data points and updating Kenya's outdated indicators. Winsorisation was used to remove the outliers from the GFSI database, while the Spearman correlation and Paired t-tests were used to test for the statistical significance of the outdated data and outliers. The study revealed that while Kenya's 2019 GFSI database did not have outliers, outliers in other countries' data points impacted Kenya's score and rank. For example, the winsorisation of outliers for other countries reduced Kenya's 2019 overall GFSI score by six points. Moreover, thirteen indicators in Kenya's 2019 GFSI database were found to be outdated. However, despite Kenya's score improving from updating the outdated data, the impact was minimal to increase the GFSI's mean score for all countries. That is, updating Kenya's outdated indicators was found not to differ significantly from zero. The study concluded that Kenya's score and rank in the 2019 GFSI were affected by the outdated data in Kenya's database and outliers in other countries' data. The study, therefore, recommended that Kenya should update its national database and allow open access to the national data while the GFSI should identify and remove outliers from the data points.

description: The collective interactions of many partons in the first stage of the collisions is the usual accepted explanation of the sizable elliptical flow. The clustering of color sources provides a framework of partonic interactions. In this scheme, we show a reasonable agreement with RHIC data for pT<1.5 GeV/c in both the dependence of v2 transverse momentum and in the shape of the nuclear modified factor on the azimuthal angle for different centralities. We show the predictions at LHC energies for Pb-Pb. In the case of proton-proton collisions a sizable v2 is obtained at this energy.

I would like to ask the following questions: What interpretations, thoughts and positions do the novels formulate in their view of the present? And what literary means do they use to do it in each case?

description: We investigate the classical capacity of two quantum channels with memory: a periodic channel with depolarizing channel branches, and a convex combination of depolarizing channels. We prove that the capacity is additive in both cases. As a result, the channel capacity is achieved without the use of entangled input states. In the case of a convex combination of depolarizing channels the proof provided can be extended to other quantum channels whose classical capacity has been proved to be additive in the memoryless case.

description: Using high resolution, high-S/N archival UVES spectra, we have performed a detailed spectroscopic analysis of 4 chemically peculiar HgMn stars (HD 71066, HD 175640, HD 178065 and HD 221507). Using spectrum synthesis, mean photospheric chemical abundances are derived for 22 ions of 16 elements. We find good agreement between our derived abundances and those published previously by other authors. For the 5 elements that present a sufficient number of suitable lines, we have attempted to detect vertical chemical stratification by analyzing the dependence of derived abundance as a function of optical depth. For most elements and most stars we find no evidence of chemical stratification with typical 3σupper limits of Δ\log N_elem/N_tot~0.1-0.2 dex per unit optical depth. However, for Mn in the atmosphere of HD 178065 we find convincing evidence of stratification. Modeling of the line profiles using a two-step model for the abundance of Mn yields a local abundance varying approximately linearly by ~0.7 dex through the optical depth range log τ_5000=-3.6 to -2.8.

description: Purely self-gravitating systems of point particles have been extensively studied in astrophysics and cosmology, mainly through numerical simulations, but understanding of their dynamics still remains extremely limited. We describe here results of a detailed study of a simple class of cold quasi-uniform initial conditions, for both finite open systems and infinite systems. These examples illustrate well the qualitative features of the quite different dynamics observed in each case, and also clarify the relation between them. In the finite case our study highlights the potential importance of energy and mass ejection prior to virialization, a phenomenon which has been previously overlooked. We discuss in both cases the validity of a mean-field Vlasov-Poisson description of the dynamics observed, and specifically the question of how particle number should be extrapolated to test for it.

description: Faraday rotation measurements have provided an invaluable technique with which to measure the properties of astrophysical magnetized plasmas. Unfortunately, typical observations provide information only about the density-weighted average of the magnetic field component parallel to the line of sight. As a result, the magnetic field geometry along the line of sight, and in many cases even the location of the rotating material, is poorly constrained. Frequently, interpretations of Faraday rotation observations are dependent upon underlying models of the magnetic field being probed (e.g., uniform, turbulent, equipartition). However, we show that at sufficiently low frequencies, specifically below roughly 13 (RM/rad m^-2)^(1/4) (B/G)^(1/2) MHz, the character of Faraday rotation changes, entering what we term the ``super-adiabatic regime'' in which the rotation measure is proportional to the integrated absolute value of the line-of-sight component of the field. As a consequence, comparing rotation measures at high frequencies with those in this new regime provides direct information about the geometry of the magnetic field along the line of sight. Furthermore, the frequency defining the transition to this new regime, nu_SA, depends directly upon the local electron density and magnetic field strength where the magnetic field is perpendicular to the line of sight, allowing the unambiguous distinction between Faraday rotation within and in front of the emission region. Typical values of nu_SA range from 10 kHz to 10 GHz, depending upon the details of the Faraday rotating environment. In particular, for resolved AGN, including the black holes at the center of the Milky Way (Sgr A*) and M81, nu_SA ranges from roughly 10 MHz to 10 GHz, and thus can be probed via existing and up-coming ground-based radio observatories.

description: Previous research from in and outside museums suggests that the haptic exploration of surfaces and objects have various educational benefits and can positively influence the museum visit experience. However, there is still a need for more research on the potential effects of object handling on museum learning, especially in science museums. The present study attempts to fill this research gap by investigating differences in museum visitors’ science learning when presenting them with photos of objects, real objects, or objects that can be handled. We used a multi-criteria approach in which we examined both cognitive and motivational-affective aspects. We found that the participants who were allowed to haptically explore the exhibition's objects showed a higher recollection of the objects and accompanying text topics and reported a higher perceived autonomy compared to the participants in the other two experimental conditions. Unexpectedly, for situational interest as well as for positive and negative affect, the participants in the photo-condition reported higher values than the participants in the other two conditions. Implications for instructional uses of tangible objects and further directions for research are discussed.

description: L’articolo fornisce una panoramica del dibattito storiografico sull’americanizzazione della televisione italiana durante i decenni della Guerra Fredda. L’obiettivo è quello di suggerire nuovi elementi e prospettive per considerare aspetti finora inesplorati dell’influenza americana sul panorama televisivo italiano. Da un lato, l’analisi si concentra sulla svolta prodotta, a metà degli anni Settanta, dalla fine del monopolio Rai e sulla conseguente tendenza a interpretare la svolta commerciale della tv italiana in termini di americanizzazione. Dall’altro, l’articolo sostiene la tesi secondo cui l’esame dell’evoluzione del sistema televisivo italiano contribuisce a fare luce sull’evoluzione del significato e delle implicazioni del processo di americanizzazione italiana tra anni Settanta e Ottanta.

The article provides an overview of the main threads and phases of the historiographical debate on the Americanization of Italian TV during the Cold War. The goal is to suggest new elements for future analyses and propose new perspectives to consider hitherto unexplored aspects of American influence over the Italian television landscape. On the one hand, the analysis focuses on the turning point produced, in the mid-1970s, by the end of Rai’s public monopoly over TV broadcasting and the subsequent tendency to interpret the commercial shift of Italian television in terms of Americanization. On the other hand, the article contends that the analysis of the evolving Italian television system can help cast light on the evolution of the meaning and implications of the Americanization process in the 1970s and 1980s.

description: All first-generation large-scale gravitational wave detectors are operated at the dark fringe and use a heterodyne readout employing radio frequency (RF) modulation-demodulation techniques. However, the experience in the currently running interferometers reveals several problems connected with a heterodyne readout, of which phase noise of the RF modulation is the most serious one. A homodyne detection scheme (DC-readout), using the highly stabilized and filtered carrier light as local oscillator for the readout, is considered to be a favourable alternative. Recently a DC-readout scheme was implemented on the GEO 600 detector. We describe the results of first measurements and give a comparison of the performance achieved with homodyne and heterodyne readout. The implications of the combined use of DC-readout and signal-recycling are considered.

description: Socio-scientific reasoning (SSR) is key to helping students take informed positions around socio-scientific issues (SSI). SSR comprises four competencies: recognising complexity of SSI’s, multiple perspectives around SSI’s, the need for ongoing inquiry around SSI’s, and skepticism around different parties’ claims made about SSI’s. The Quantitative Assessment of SSR (QuASSR) provides a promising measurement framework, but there are still important questions around the ability of this instrument to measure transfer across different scenarios and change in SSR over an intervention. Further, prior work suggests that the four competencies may constitute a progression. We explored the ability of the QuASSR to measure transfer of SSR across three different SSI’s using 2-faceted and multi-faceted Rasch models. We used path analysis to test the hypothesis that competencies associated with SSR formed a progression. We found transfer or neartransfer of SSR across the three scenarios, and that the competencies comprise a unidimensional hierarchy. Perspective-taking is a necessary bridge between students’ understanding of complexity and the higher-level competencies of inquiry and skepticism. Inquiry and skepticism were found to be conditionally independent upon accounting for perspective-taking, supporting the idea that seeing multiple perspectives around SSI’s is central to development of the other SSR competencies.

description: In this review, we present and discuss the most recent results on inclusive and exclusive diffractive processes at HERA and Tevatron colliders. Measurements from fixed target experiments at HERMES and Jefferson laboratory are also reviewed. The complementarity of all these results is analysed in the context of perturbative QCD and new challenging issues in nucleon tomography are studied. A first understanding of how partons are localised in the nucleon to build orbital momenta can be addressed with these experimental results. Some prospects are outlined for new measurements in fixed target kinematic, at Jefferson laboratory and CERN, at COMPASS, or at the LHC. Of special interest is the exclusive (coherent) production of Higgs boson and heavy objects at the LHC. Based on the present knowledge, some perspectives are presented in this direction.

The role of behavior in the interaction of underyearling coho and steelhead (Oncorhynchus kisutch and Salmo gairdnerii)
Creators: name: Hartman, Gordon Frederick
Publisher: name: University of British Columbia
Year: 2011

description: Two similar salmonids, coho and steelhead, cohabit many coastal rivers of British Columbia. Field collections reveal that the distributions of underyearling coho and steelhead are similar along the length of these streams. However, the microhabitat distribution of the two species is different. In spring and summer, when population densities are high, coho occupy pools, trout occupy riffles. In autumn and winter, when numbers are lower, both species inhabit the pools. Nilsson (1956) stated that segregation (such as that shown by coho and trout in spring and summer) may be indicative of competition resulting from similar ecological demands. To test this hypothesis the distribution and behavior of coho and steelhead were compared in a stream aquarium at different seasons with gradients of light, cover, depth or depth/velocity and in experimental riffles and pools. Distributions, and preferences of the two species in the experimental environments were most similar in spring and summer, the seasons when segregation occurred in nature, and least similar in autumn and winter, the seasons when the two species occurred together in nature. Spring and summer segregation in the streams is probably the result of interaction which is produced by ecological similarities of the species and accentuated by dense populations and inherently high levels of aggressiveness. The species do not segregate in streams in winter because certain ecological demands are different, numbers are lower and inherent levels of aggressiveness are low. When the two species were together in the experimental riffle and pool environment, trout were aggressive and defended areas in riffles .but not in pools; coho were aggressive in pools but less inclined to defend space in the riffles. These differences in behavior probably account for the distribution of trout and coho in natural riffles and pools. The data support the basic contention of Nilsson (1956) and illustrate the role of behavior in segregation produced by competition for space.
title: Fractional-order system identification in massive MIMO systems

description: Fifth generation (5G) wireless communication systems promise increased capacity, increased data rate, enhanced reliability, reduced latency, improved energy efficiency, improved spectrum efficiency and reduced interference, and massive multiple-input multiple-output (MIMO) has been identified as a driving technique in achieving this. In massive MIMO, the base station is equipped with hundreds of antennas to service tens of terminals in the same time-frequency resource. But there are several challenges associated with massive MIMO that prevent the achievement of these benefits, and these include channel estimation, pilot contamination and radio frequency (RF) impairments, etc. The main focus of this thesis is on the use of continuous-time statespace models to identify the dynamics of massive MIMO wireless channels, i.e. channel estimation. Two identification models, namely the continuous-time integer-order state-space and continuous-time fractional-order state-space identification models are considered when identifying the massive MIMO frequency-selective wireless channels. These models are designed based on the multiple-input multiple-output output-error state space (MOESP) algorithm, a subspace system identification algorithm that has been proven to successfully identify the dynamics of a system. Through simulations it is shown that with increase in model order, the continuous-time integer-order state-space model is able to model the massive MIMO channels with increased accuracy. The performance of the continuous-time fractionalorder state-space model is also studied for different fractional-order values, and its performance is then compared with that of the continuous-time integer-order state-space model. Having identified the dynamics of the massive MIMO system, equalizers are then designed to help combat the effects of inter-symbol interference (ISI) caused by the massive multiple-input multiple-output (MIMO) frequency-selective wireless channels. We propose the use of state-space models for channel equalization. The minimum mean square error – decision feedback equalizer (MMSE-DFE) is the equalizer of choice in addressing the ISI and is built based on the continuous-time integer-order state-space and continuous-time fractional-order state-space identified models.

description: Transport properties of an interacting triple quantum dot system coupled to three leads in a triangular geometry has been studied in the Kondo regime. Applying mean-field finite-U slave boson and embedded cluster approximations to the calculation of transport properties unveils a set of rich features associated to the high symmetry of this system. Results using both calculation techniques yield excellent overall agreement and provide additional insights into the physical behavior of this interesting geometry. In the case when just two current leads are connected to the three-dot system, interference effects between degenerate molecular orbitals are found to strongly affect the overall conductance. An S=1 Kondo effect is also shown to appear for the perfect equilateral triangle symmetry. The introduction of a third current lead results in an `amplitude leakage' phenomenon, akin to that appearing in beam splitters, which alters the interference effects and the overall conductance through the system.

We propose that such an excess can be caused by the additional energy injected by fast mode waves refracted in the higher atmosphere due to the rapid increase of the Alfven speed. Our model qualitatively explains the magnitude of the halo and allows to make some predictions of its behavior that can be checked in future observations.

description: Among many other physical and biogeochemical processes, oceanic upwelling is a major contributor to the primary productivity of oceans. In the present study, sixteen models from the ‘Coupled Climate Model Inter-comparison Project phase 5’ (CMIP5) are assessed for their capability in simulating the Chlorophyll (Chl-a) concentration against satellite observations over the northern Indian Ocean. The sixteen CMIP5 models are categorized into three groups based on their relative skill, Group-A models had the highest skill and captured the phase of the bloom during summer monsoon season whereas the Group-B and Group-C models mostly failed to reproduce the Chl-a concentrations. The observed interannual variations were poorly simulated by all the CMIP5 models. Group-A models showed a negative bias in Chl-a concentration over the northern Arabian Sea and a positive bias in Chl-a simulation off Somalia over the western Indian Ocean. High Chl-a associated with the coastal upwelling along the west coasts of India and Sri Lanka was poorly simulated by CMIP5 models. The study highlights the regional deficiency in CMIP5 climate models in simulating Chl-a and the need for improved coupled physical-biogeochemical models over the tropical Indian Ocean.

description: The statistical mechanics of periodically driven ("Floquet") systems in contact with a heat bath exhibits some radical differences from the traditional statistical mechanics of undriven systems. In Floquet systems all quasienergies can be placed in a finite frequency interval, and the number of near degeneracies in this interval grows without limit as the dimension N of the Hilbert space increases. This leads to pathologies, including drastic changes in the Floquet states, as N increases. In earlier work these difficulties were put aside by fixing N, while taking the coupling to the bath to be smaller than any quasienergy difference. This led to a simple explicit theory for the reduced density matrix, but with some major differences from the usual time independent statistical mechanics. We show that, for weak but finite coupling between system and heat bath, the accuracy of a calculation within the truncated Hilbert space spanned by the N lowest energy eigenstates of the undriven system is limited, as N increases indefinitely, only by the usual neglect of bath memory effects within the Born and Markov approximations. As we seek higher accuracy by increasing N, we inevitably encounter quasienergy differences smaller than the system-bath coupling. We therefore derive the steady state reduced density matrix without restriction on the size of quasienergy splittings. In general, it is no longer diagonal in the Floquet states. We analyze, in particular, the behavior near a weakly avoided crossing, where quasienergy near degeneracies routinely appear. The explicit form of our results for the denisty matrix gives a consistent prescription for the statistical mechanics for many periodically driven systems with N infinite, in spite of the Floquet state pathologies.

description: We prove that the interval topology of an Archimedean atomic lattice effect algebra $E$ is Hausdorff whenever the set of all atoms of $E$ is almost orthogonal. In such a case $E$ is order continuous. If moreover $E$ is complete then order convergence of nets of elements of $E$ is topological and hence it coincides with convergence in the order topology and this topology is compact Hausdorff compatible with a uniformity induced by a separating function family on $E$ corresponding to compact and cocompact elements. For block-finite Archimedean atomic lattice effect algebras the equivalence of almost orthogonality and s-compact generation is shown. As the main application we obtain the state smearing theorem for these effect algebras, as well as the continuity of $\oplus$-operation in the order and interval topologies on them.

description: In this letter we discuss cosmological first order phase transitions with de Sitter bubbles nucleating on (inhomogeneous) matter backgrounds. The de Sitter bubble can be a toy model for an inflationary phase of universes like our own. Using the thin wall approximation and the Israel junction method we trace the classical evolution of the formed bubbles within a compound model. We first address homogeneous ambient space (FRW model) and already find that bubbles nucleated in a dust dominated background cannot expand. For an inhomogeneous dust background (LTB model) we describe cases with at least initially expanding bubbles. Yet, an ensuing passage of the bubble wall through ambient curvature inhomogeneities remains unnoticed for observers inside the bubble. Notable effects also for interior observers are found in the case of a rapid background phase transition in a FRW model.

description: Staphylococcus epidermidis is one of the major causes of nosocomial infections around the globe that leads to a high rate of mortality and morbidity in both immunocompromised patients and preterm infants. Despite the alarming increase in multi-drug resistance, no promising vaccines are readily available against this pathogen. Thus, the present study is focused on designing a multi-epitope subunit vaccine using five antigenic proteins of S. epidermidis through an immunoinformatics approach. The final vaccine comprised B-cell, HTL, and CTL binding epitopes followed by Lipoprotein LprA adjuvant added at N-terminal to augment the immunogenicity. Physicochemical assessment of the vaccine reveals the antigenic and non-allergic nature. The vaccine structure was designed, refined, validated, and disulfide engineered to obtain the best model. Molecular docking and dynamics simulation of the proposed vaccine with toll-like receptors (TLR-2 and TLR-4) showed strong and stable interactions. MM-PBSA analysis was implemented as an efficient tool to determine the intermolecular binding free energies of the system. The vaccine was subjected to immune simulation to predict its immunogenic profile. In silico cloning suggested that the proposed vaccine can be expressed efficiently in E.coli. Furthermore, in vivo animal experiment is needed to determine the effectiveness of the in silico designed vaccine. Communicated by Ramaswamy H. Sarma

description: We present results from a multi-year monitoring campaign of the broad-line radio galaxy 3C 120, using the Rossi X-ray Timing Explorer (RXTE) for nearly five years of observations. Additionally, we present coincident optical monitoring using data from several ground-based observatories. Both the X-ray and optical emission are highly variable and appear to be strongly correlated, with the X-ray emission leading the optical by 28 days. The X-ray power density spectrum is best fit by a broken power law, with a low-frequency slope of -1.2, breaking to a high-frequency slope of -2.1, and a break frequency of log nu_b=-5.75 Hz, or 6.5 days. This value agrees well with the value expected based on 3C 120's mass and accretion rate. We find no evidence for a second break in the power spectrum. Combined with a moderately soft X-ray spectrum (Gamma=1.8) and a moderately high accretion rate (mdot / mdot_Edd ~ 0.3), this indicates that 3C 120 fits in wellwith the high/soft variability state found in most other AGNs. Previous studies have shown that the spectrum has a strong Fe K-alpha line, which may be relativistically broadened. The presence of this line, combined with a power spectrum similar to that seen in Seyfert galaxies, suggests that the majority of the X-ray emission in this object arises in or near the disk, and not in the jet.
