title: Three essays on FDI, human capital and structural change
Creators: name: De Miranda Pineli Alves, André Gustavo
Publisher: name: University of Reading
Year: 2020

description: Economic development is a complex process in which aggregate output growth is accompanied by changes in the sectoral structures of output and employment. Although scholars like Simon Kuznets and Hollis Chenery have demonstrated, from the late 1950s, the quantitative importance of structural change, the issue remained largely ignored by mainstream economists, who tended to treat structural change as a by-product of growth of lesser importance. However, over the last two decades the interest on the topic has been revigorated, fuelled by concerns about premature deindustrialisation and the viability of alternative routes to prosperity. This Thesis aims to contribute to the growing literature on the causes and consequences of structural change focusing on two issues that are still largely neglected. First, it investigates whether the effect of human capital on aggregate economic growth depends on the type of economic specialisation of the country. Most cross-country studies do not find a significant positive effect of human capital on growth. Failure in taking the demand for skilled labour into account may be the cause. The estimations suggest the existence of a complementarity between human capital endowment and economic specialisation, proxied by the Economic Complexity Index. Second, the Thesis investigates whether foreign direct investment (FDI) contributes to structural change in host economies. Inspired by stages-of-development approaches to FDI such as the Investment Development Path framework, it tests, for a group of developing countries, whether aggregate FDI affects the employment structure, whether the effect depends on the sectoral concentration of FDI and whether this vary according to the stage of development of the country. In a separate chapter, it investigates, using industry-level data of post-communist countries, whether the effect of FDI on productivity growth and structural change depends on institutional quality, human capital endowment, participation in global value chains (GVCs) and alignment to comparative advantage.

description: Significant progress is being made concerning the development of oligonucleotides as therapeutic agents. Studies with antisense, siRNA, and other forms of oligonucleotides have shown promise in cellular and animal models and in some clinical studies. Nonetheless our understanding of how oligonucleotides function in cells and tissues is really quite limited. One major issue concerns the modes of uptake and intracellular trafficking of oligonucleotides, whether as ‘free’ molecules, or linked to various delivery moieties such as nanoparticles or targeting ligands. In this review we examine the recent literature on oligonucleotide internalization and subcellular trafficking in the context of current insights into the basic machinery for endocytosis and intracellular vesicular traffic.

description: Fluorescent biosensors based on environmentally sensitive dyes enable visualization and quantification of endogenous protein activation within living cells. Merocyanine dyes are especially useful for live cell imaging applications as they are extraordinarily bright, have long wavelengths of excitation and emission, and can exhibit readily detectable fluorescence changes in response to environment. We sought to systematically examine the effects of structural features on key photophysical properties, including dye brightness, environmental responsiveness, and photostability, through the synthesis of a library of 25 merocyanine dyes, derived from combinatorial reaction of 5 donor and 5 acceptor heterocycles. Four of these dyes showed optimal properties for specific imaging applications and were subsequently prepared with reactive side chains and enhanced aqueous solubility using a one-pot synthetic method. The new dyes were then applied within a biosensor design for Cdc42 activation, where dye mero60 showed a remarkable 1470% increase in fluorescence intensity on binding activated Cdc42 in vitro. The dye-based biosensors were used to report activation of endogenous Cdc42 in living cells.

description: Large-scale quantum networks require the implementation of long-lived quantum memories as stationary nodes interacting with qubits of light. Epitaxially grown quantum dots hold great potential for the on-demand generation of single and entangled photons with high purity and indistinguishability. Coupling these emitters to memories with long coherence times enables the development of hybrid nanophotonic devices incorporating the advantages of both systems. Here we report the first GaAs/AlGaAs quantum dots grown by droplet etching and nanohole infilling method, emitting single photons with a narrow wavelength distribution (736.2 $\pm$ 1.7 nm) close to the zero-phonon line of Silicon-vacancy centers. Polarization entangled photons are generated via the biexciton-exciton cascade with a fidelity of (0.73 $\pm$ 0.09). High single photon purity is maintained from 4 K (g$^($$^2$$^)$(0) = 0.07 $\pm$ 0.02) up to 80 K (g$^($$^2$$^)$(0) = 0.11 $\pm$ 0.01), therefore making this hybrid system technologically attractive for real-world quantum photonic applications.

description: Ineffective delivery to intracellular sites of action is one of the key limitations to the use of antisense and siRNA oligonucleotides as therapeutic agents. Here, we describe molecular scale antisense oligonucleotide conjugates that bind selectively to a cell surface receptor, are internalized, and then partially escape from nonproductive endosomal locations to reach their sites of action in the nucleus. Peptides that include bombesin sequences for receptor targeting and a run of histidine residues for endosomal disruption were covalently linked to a splice switching antisense oligonucleotide. The conjugates were tested for their ability to correct splicing and up-regulate expression of a luciferase reporter in prostate cancer cells that express the bombesin receptor. We found that trivalent conjugates that included both the targeting sequence and several histidine residues were substantially more effective than conjugates containing only the bombesin or histidine moieties. This demonstrates the potentia...

description: In order to describe elastic waves propagation in metamaterials, i.e. solids with heterogeneities or microstructure, it is necessary to consider non-local or higher-order models. The relaxed micromorphic model (RMM) proposed here can describe these effects as a continuous material with enriched kinematics. We present a new unit cell giving rise to a metamaterial for acoustic application. The microstructure is engineered to show a band-gap in the low acoustic regime (600-2000 Hz) for which waves cannot propagate through the material. We concentrate on the size effects to make full advantage of the particularly beneficial structure that the model provides. The RMM material parameters are fitted using a new algorithm relying on cutoffs and asymptotes (obtained via a Bloch-Floquet analysis). In particular, by enhancing the kinetic energy of the model with a new inertia term, we enable decreasing curves (modes with negative group velocity).

description: : Here we consider the gypsum mineral to investigate its broad scan Raman spectrum. The presence of water of crystallization is detected and its OH-stretching spectral region deconvoluted in q-Gaussian functions. That is, we follow the same approach that we used recently for minerals of the natrolite and vivianite groups. In the case of gypsum, we consider the Raman data from Rappal Sangameswaran Krishnan, 1945, and compare the bands given in his work with the components that we can obtain from the spectra provided by RRUFF database. We find a remarkable agreement between R. S. Krishnan’s data and the decompositions in q-Gaussian functions. We will describe also the experimental method used by Krishnan, based on the Franco Rasetti technique with mercury resonance radiation excitation. In the RRUFF database, we can also find an infrared spectrum; we considered it and decomposed in q-Gaussian and q-BWF functions.

description: A long-lived qubit is usually well-isolated from all other systems and the environments, and so is not easy to couple with measurement apparatus. It is sometimes difficult to implement reliable projective measurements on such a qubit. One potential solution is spin amplification with many ancillary qubits. Here, we propose a spin amplification technique, where the ancillary qubits state change depending on the state of the target qubit. The technique works even in the presence of inhomogeneous broadening. We show that fast and accurate amplification is possible even if the coupling and frequency of the ancillary qubits is inhomogeneous. Since our scheme is robust against realistic imperfections, this could provide a new mechanism for reading out a single spin that could not have been measured using the previous approaches.

description: The Effective Field Theory (EFT) of perturbations on an arbitrary background geometry with a timelike scalar profile was recently constructed in the context of scalar-tensor theories. In this paper, we use this EFT to study quasinormal frequencies of odd-parity perturbations on a static and spherically symmetric black hole background. Keeping a set of operators that can accommodate shift-symmetric quadratic higher-order scalar-tensor theories, we demonstrate the computation for two examples of hairy black holes, of which one is the stealth Schwarzschild solution and the other is the Hayward metric accompanied by a non-trivial scalar field. We emphasize that this is the first phenomenological application of the EFT, opening a new possibility to test general relativity and modified gravity theories in the strong gravity regime.

description: Der vorliegende Beitrag konturiert zunächst die Herausbildung der Timurbewegung in der DDR, um dann die damit verbundenen pädagogischen und gesellschaftlichen Zielstellungen genauer zu beleuchten. Anhand der überlieferten Pädagogischen Lesungen zu diesem Thema werden Intentionen der involvierten Fachkräfte und die daraus entwickelten Methoden der angeleiteten Timurarbeit in den 1970er und 1980er Jahren im diachronen Verlauf betrachtet. Dabei wird eine sich verändernde Bezugnahme auf das legitimierende Narrativ, Gaidars Jugendroman „Timur und sein Trupp“, konturiert. Hier wird deutlich, dass die Timurarbeit mit Kindern in der DDR weniger im Dienste der praktischen Unterstützung von Bedürftigen als vielmehr zur Umsetzung von Erziehungszielen im Kontext der „Herausbildung sozialistischer Persönlichkeiten“ befördert wurde. Die Autorinnen verdeutlichen, dass sie dies nur mit starker Lenkung für realisierbar halten und deshalb zentrale im Roman geschilderte Helferformate in eigene, stark angeleitete, organisatorische Lösungen überführen. Auch dieser versuchte Spagat verhindert wohl, dass das zweifellos vorhandene Potential der literarischen Vorlage für eine hohe intrinsische Motivation der beteiligten Timurhelfer*innen wirklich zum Tragen kam. Die Timurhilfe ist und bleibt in diesen beiden Dekaden ein an Lehrkraft oder Pionierleiter*in gekoppeltes Format.

description: Since identifying the gap in the H-R Diagram (HRD) marking the transition between partially and fully convective interiors, a unique type of slowly pulsating M dwarf has been proposed. These unstable M dwarfs provide new laboratories in which to understand how changing interior structures can produce potentially observable activity at the surface. In this work, we report the results of the largest high-resolution spectroscopic H$α$ emission survey to date spanning this transition region, including 480 M dwarfs observed using the CHIRON spectrograph at CTIO/SMARTS 1.5-m. We find that M dwarfs with H$α$ in emission are almost entirely found 0 to 0.5 magnitude above the top edge of the gap in the HRD, whereas effectively no stars in and below the gap show emission. Thus, the top edge of the gap marks a relatively sharp activity transition, and there is no anomalous H$α$ activity for stars in the gap. We also identify a new region at 10.3 $

description: We report a switchable redox click and cleave reaction strategy for conjugating and releasing a range of molecules on demand. This chemoselective redox-responsive ligation (CRRL) and release strategy is based on a redox switchable oxime linkage that is controlled by mild chemical or electrochemical redox signals and can be performed at physiological conditions without the use of a catalyst. Both conjugation and release reactions are kinetically well behaved and quantitative. The CRRL strategy is synthetically modular and easily monitored and characterized by routine analytical techniques. We demonstrate how the CRRL strategy can be used for the dynamic generation of cyclic peptides and the ligation of two different peptides that are stable but can be selectively cleaved upon changes in the redox environment. We also demonstrate a new redox based delivery of cargoes to live cells strategy via the CRRL methodology by synthesizing a FRET redox-responsive probe that is selectively activated within a cellular environment. We believe the ease of the CRRL strategy should find wide use in a range of applications in biology, tissue engineering, nanoscience, synthetic chemistry, and material science and will expand the suite of current conjugation and release strategies.

description: We study theoretically internal flows in a small oblate droplet suspended on the circular frame. Marangoni convection arises due to a vertical temperature gradient across the drop and is driven by the surface tension variations at the free drop interface. Using the analytical basis for the solutions of Stokes equation in coordinates of oblate spheroid we have derived the linearly independent stationary solutions for Marangoni convection in terms of Stokes stream functions. The numerical simulations of the thermocapillary motion in the drops are used to study the onset of the stationary regime. Both analytical and numerical calculations predict the axially-symmetric circulatory convection motion in the drop, the dynamics of which is determined by the magnitude of the temperature gradient across the drop. The analytical solutions for the critical temperature distribution and velocity fields are obtained for the large temperature gradients across the oblate drop. These solutions reveal the lateral separation of the critical and stationary motions within the drops. The critical vortices are localized near the central part of a drop, while the intensive stationary flow is located closer to its butt end. A crossover to the limit of the plane film is studied within the formalism of the stream functions by reducing the droplet ellipticity ratio to zero value. The initial stationary regime for the strongly oblate drops becomes unstable relative to the many-vortex perturbations in analogy with the plane fluid films with free boundaries.

description: The fast kinetics and bioorthogonal nature of the tetrazine trans-cyclooctene (TCO) ligation makes it a unique tool for PET probe construction. In this study, we report the development of an 18F-labeling system based on a CF3-substituted diphenyl-s-tetrazine derivative with the aim of maintaining high reactivity while increasing in vivo stability. c(RGDyK) was tagged by a CF3-substituted diphenyl-s-tetrazine derivative via EDC-mediated coupling. The resulting tetrazine-RGD conjugate was combined with a 19F-labeled TCO derivative to give HPLC standards. The analogous 18F-labeled TCO derivative was combined with the diphenyl-s-tetrazine-RGD at μM concentration. The resulting tracer was subjected to in vivo metabolic stability assessment, and microPET studies in murine U87MG xenograft models. The diphenyl-s-tetrazine-RGD combines with an 18F-labeled TCO in high yields (>97% decay-corrected on the basis of TCO) using only 4 equiv of tetrazine-RGD relative to the 18F-labeled TCO (concentration calculated based on product’s specific activity). The radiochemical purity of the 18F-RGD peptides was >95% and the specific activity was 111 GBq/μmol. Noninvasive microPET experiments demonstrated that 18F-RGD had integrin-specific tumor uptake in subcutaneous U87MG glioma. In vivo metabolic stability of 18F-RGD in blood, urine and major organs showed two major peaks: one corresponded to the Diels-Alder conjugate and the other was identified as the aromatized analog. A CF3-substituted diphenyl-s-tetrazine displays excellent speed and efficiency in 18F-PET probe construction, providing nearly quantitative 18F labeling within minutes at low micromolar concentrations. The resulting conjugates display improved in vivo metabolic stability relative to our previously described system.

description: The electron-detachment energy is measured by its ionization potential (IP). As a result, it is a fundamental observable and important molecular electronic signature in photoelectron spectroscopy. A precise theoretical prediction of electron-detachment energies or ionization potentials is essential for organic optoelectronic systems like transistors, solar cells, or light-emitting diodes. In this work, we benchmark the performance of the recently presented IP variant of the equation-of-motion pair coupled cluster doubles (IP-EOM-pCCD) model to determine IPs. Specifically, the predicted ionization energies are compared to experimental results and higher-order coupled cluster theories based on statistically assessing 201 electron-detached states of 41 organic molecules for three different molecular orbital basis sets and two sets of particle-hole operators. While IP-EOM-pCCD features a reasonable spread and skewness of ionization energies, its mean error and standard deviation deviate up to 1.5 eV from reference data. Our study, thus, highlights the importance of dynamical correlation to reliably predict IPs from a pCCD reference function in small organic molecules.

description: Two aerobic, lab-scale, slurry-phase bioreactors were used to examine the biodegradation of polycyclic aromatic hydrocarbons (PAHs) in contaminated soil and the associated bacterial communities. The two bioreactors were operated under semi-continuous (draw-and-fill) conditions at a residence time of 35 days, but one was fed weekly and the other monthly. Most of the quantified PAHs, including high-molecular-weight compounds, were removed to a greater extent in the weekly-fed bioreactor, which achieved total PAH removal of 76%. Molecular analyses, including pyrosequencing of 16S rRNA genes, revealed significant shifts in the soil bacterial communities after introduction to the bioreactors and differences in the abundance and types of bacteria in each of the bioreactors. The weekly-fed bioreactor displayed a more stable bacterial community with gradual changes over time, whereas the monthly-fed bioreactor community was less consistent and may have been more strongly influenced by the influx of untreated soil during feeding. Phylogenetic groups containing known PAH-degrading bacteria previously identified through stable-isotope probing of the untreated soil were differentially affected by bioreactor conditions. Sequences from members of the Acidovorax and Sphingomonas genera, as well as the uncultivated ‘‘Pyrene Group 2’’ were abundant in the bioreactors. However, the relative abundances of sequences from the Pseudomonas, Sphingobium, and Pseudoxanthomonas genera, as well as from a group of unclassified anthracene degraders, were much lower in the bioreactors compared to the untreated soil.

description: Doping of III-nitride based compound semiconductor nanowires is still a challenging issue to have a control over the dopant distribution in precise locations of the nanowire optoelectronic devices. Knowledge of the dopant incorporation and its pathways in nanowires for such devices is limited by the growth methods. We report the direct evidence of incorporation pathway for Mg dopants in p-type nonpolar GaN nanowires grown via vapour-liquid-solid (VLS) method in a chemical vapour deposition technique for the first time. Mg incorporation is confirmed using X-ray photoelectron (XPS) and electron energy loss spectroscopic (EELS) measurements. Energy filtered transmission electron microscopic (EFTEM) studies are used for finding the Mg incorporation pathway in the GaN nanowire. Photoluminescence studies on Mg doped GaN nanowires along with the electrical characterization on heterojunction formed between nanowires and n-Si confirm the activation of Mg atoms as p-type dopants in nonpolar GaN nanowires.

description: A continuous-flow column study was conducted to evaluate the long-term effects of in situ biostimulation on the biodegradation of polycyclic aromatic hydrocarbons (PAHs) in soil from a manufactured gas plant site. Simulated groundwater amended with oxygen and inorganic nutrients was introduced into one column, while a second column receiving unamended groundwater served as a control. PAH and dissolved oxygen (DO) concentrations, as well as microbial community profiles, were monitored along the column length immediately before and at selected intervals up to 534 days after biostimulation commenced. Biostimulation resulted in significantly greater PAH removal than in the control condition (73% of total measured PAHs vs. 34%, respectively), with dissolution accounting for a minor amount of the total mass loss (~6%) in both columns. Dissolution was most significant for naphthalene, acenaphthene, and fluorene, accounting for >20% of the total mass removed for each. A known group of PAH-degrading bacteria, ‘Pyrene Group 2’ (PG2), was identified as a dominant member of the microbial community and responded favorably to biostimulation. Spatial and temporal variations in soil PAH concentration and PG2 abundance were strongly correlated to DO advancement, although there appeared to be transport of PG2 organisms ahead of the oxygen front. At an estimated oxygen demand of 6.2 mg O2/g dry soil and a porewater velocity of 0.8 m/day, it took between 374 and 466 days for oxygen breakthrough from the 1-m soil bed in the biostimulated column. This study demonstrated that the presence of oxygen was the limiting factor in PAH removal, as opposed to the abundance and/or activity of PAH-degrading bacteria once oxygen reached a previously anoxic zone.

description: Este trabajo describe cómo llevar a la práctica un huerto escolar ecológico en un colegio Montessori, en el segundo ciclo de Educación Infantil. Primero se argumentará la importancia del contacto con la naturaleza en la infancia, y se presentará el huerto escolar como un valioso recurso educativo, que proporciona un contexto de aprendizaje fuera de las paredes del aula. Como se explicará, el huerto posibilita experiencias que contribuyen al desarrollo de los niños y niñas y al conocimiento del medio natural, favoreciendo la toma de conciencia sobre la importancia de su conservación. Asimismo, constituye un medio para educar en hábitos de alimentación saludables. A continuación se revisará la pedagogía Montessori y sus principios fundamentales, donde se destaca el aprendizaje mediante las propias experiencias en un ambiente preparado para satisfacer las necesidades del alumnado, promoviendo su independencia y estimulando su deseo de conocer. Finalmente, en este proyecto se desarrollará el diseño de un huerto, su puesta en marcha y su mantenimiento, teniendo en cuenta la participación de toda la comunidad educativa. El objetivo es conseguir que el espacio exterior del colegio forme parte del ambiente educativo, donde los niños y las niñas puedan trabajar de forma independiente y en contacto con la naturaleza. Abstract: This work describes how to develop an organic vegetable garden in a Montessori school in early years education. First, the importance of contact with nature in the childhood is argued and the vegetable garden is presented as a valuable education resource that provides a learning environment outside the classroom. It is explained how the garden provides experiences that contribute to children development and to the knowledge of nature, increasing the awareness of the importance of its conservation. Moreover, it is also a means of conveying healthy food habits. Next, the Montessori pedagogy and its fundamental principles are reviewed, highlighting learning by experience in an environment prepared to meet the students needs, promoting their independence and favoring their drive to learn. Finally, this project lays out the design of a vegetable garden and its maintenance at the school, taking into account the role of the whole learning community. The goal is to incorporate the school outdoors to learning environment, where children can work independently and close to nature.

description: Deep brain stimulation is an established treatment for Parkinson’s disease (PD). However, to advance its effectiveness, researchers need to gain a better understanding of the action mechanism by means of in vivo and in silico studies. This thesis presents neural activation patterns theoretically beneficial for motor improvement in PD and analyzes their theoretical reproducibility in a rat brain. Besides, it elucidates biophysical and computational problems to be addressed in order to optimize animal studies and avoid misconceptions when transferring experimental findings to clinical trials.

description: It is customary to employ a semi-spherical scale model to describe the apparent path of the Sun across the sky, whether it be its diurnal motion or its variation throughout the year. A flat surface and three bent semi-rigid wires (representing the three solar arcs during solstices and equinoxes) will do the job. On the other hand, since very early times, there have been famous armillary spheres built and employed by the most outstanding astronomers for the description of the celestial movements. In those instruments, many of them now considered true works of art, Earth lies in the center of the cosmos and the observer looks at the whole "from the outside." Of course, both devices, the scale model of the sky and the armillary sphere, serve to represent the movement of the Sun, and in this paper we propose to show their equivalence by a simple construction. Knowing the basics underlying the operation of the armillary sphere will give us confidence to use it as a teaching resource in school.

description: Configurationally disordered crystalline boron carbide, B$_{4}$C, is studied using first-principles calculations. We investigate both dilute and high concentrations of carbon-boron substitutional defects. For the latter purpose, we suggest a superatom's picture of the complex structure and combine it with a special quasi-random structure approach for disorder. In this way, we model a random distribution of high concentrations of the identified low-energy defects: 1) Bipolar defects and 2) Rotation of icosahedral carbon among the three polar-up sites. Additionally, the substitutional disorder of the icosahedral carbon at all six polar sites, as previously discussed in the literature, is also considered. Two configurational phase transitions from the ordered to the disordered configurations are predicted to take place upon increasing temperature using a mean-field approximation for the entropy. The first transition, at 870 K, induces substitutional disorder of the icosahedral carbon atoms among the three polar-up sites, meanwhile the second transition, at 2325 K, reveals the random substitution of the icosahedral carbon atoms at all six polar sites coexisting with bipolar defects. Already the first transition removes the monoclinic distortion existing in the ordered ground state configuration and restore the rhombohedral system (R3m). The restoration of inversion symmetry yielding the full rhombohedral symmetry (R-3m) on average, corresponding to what is reported in the literature, is achieved after the second transition. The electronic density of states, obtained from the disordered phases indicates a sensitivity of band gap to the degree of configurational disorder in B$_{4}$C.

description: Plasminogen activator inhibitor-1 (PAI-1) is a physiological inhibitor of urokinase (uPA), a serine protease known to promote cell migration and invasion. Intuitively, increased levels of PAI-1 should be beneficial in down-regulating uPA activity, particularly in cancer. By contrast, in vivo, increased levels of PAI-1 are associated with a poor prognosis in breast cancer. This phenomenon is termed the “PAI-1 paradox”. Many factors are responsible for the upregulation of PAI-1 in the tumor micro-environment. We hypothesize that there is a breast cancer predisposition to a more aggressive stage when PAI-1 is upregulated as a consequence of Metabolic Syndrome (MetS). MetS exerts a detrimental effect on the breast tumor microenvironment that supports cancer invasion. People with MetS have an increased risk of coronary heart disease, stroke, peripheral vascular disease and hyper-insulinemia. Recently, MetS has also been identified as a risk factor for breast cancer. We hypothesize the existence of the “PAI-1 cycle”. Sustained by MetS, adipocytokines alter PAI-1 expression to promote angio-genesis, tumor-cell migration and procoagulant micro-particle formation from endothelial cells, which generates thrombin and further propagates PAI-1 synthesis. All of these factors culminate in a chemotherapy-resistant breast tumor microenvironment. The PAI-1 cycle may partly explain the PAI-1 paradox. In this hypothesis paper, we will discuss further how MetS upregulates PAI-1 and how an increased level of PAI-1 can be linked to a poor prognosis.

description: Changes in land use and climate influence the methane balance of fen peatlands, and the peat microbial communities involved in methane transformation. Microbial communities, however, have rarely been studied in fens in this context. In this thesis, I used high-throughput 16S rRNA gene amplicon sequencing of DNA and cDNA, qPCR, and geochemical analyses to assess how rewetting and drying of fens influences methane producers (methanogens) and consumers (methanotrophs). Fen rewetting promoted the establishment of methanogens, while short-term drought promoted methanotroph establishment.
