description: Prospects for quarkonium-production studies accessible during the upcoming high-luminosity phases of the CERN Large Hadron Collider operation after 2021 are reviewed. Current experimental and theoretical open issues in the field are assessed together with the potential for future studies in quarkonium-related physics. This will be possible through the exploitation of the huge data samples to be collected in proton-proton, proton-nucleus and nucleus-nucleus collisions, both in the collider and fixed-target modes. Such investigations include, among others, those of: (i) J/psi and Upsilon produced in association with other hard particles; (ii) chi(c,b) and eta(c,b) down to small transverse momenta; (iii) the constraints brought in by quarkonia on gluon PDFs, nuclear PDFs, TMDs, GPDs and GTMDs, as well as on the low-x parton dynamics; (iv) the gluon Sivers effect in polarised-nucleon collisions; (v) the properties of the quark-gluon plasma produced in ultra-relativistic heavy-ion collisions and of collective partonic effects in general; and (vi) double and triple parton scatterings.

Party politics in a non-western democracy : a test of competing theories of party system change, government formation and government stability in India
Creators: name: Nikolenyi, Csaba
Publisher: name: University of British Columbia
Year: 2009

description: The dissertation will address the ongoing debate in Comparative Politics about the virtues and pathologies of rational choice theory by testing competing hypotheses and predictions to account for three aspects of party politics in India: the transformation of the Indian political party system from a predominant to an even multiparty system; the politics of government formation; and the politics of government stability. Overall, the dissertation will pursue two arguments. First, rational choice models and predictions can account for the empirical cases more consistently than hypotheses and predictions derived from other paradigms. Second, by using India as the case on which to test competing theories, it will be shown that non-Western political phenomena are not sui generis and they may be accounted for in terms of comparative theory the same way as Western phenomena have been.

description: Phoenix sylvestris (Arecaceae family) known as Indian Date Palm has been identified as a component of traditional medicine against various ailments. The present study was focused on phytochemical screening of crude hexane, dichloromethane and methanol leaf extracts. The crude extracts showed the presence of alkaloids, flavonoids, and phenols in the plant leaves. In the study methanol extract was found most potent, so this extract was further fractionated by column chromatography and 9 methanol purified fractions (MPFs) were isolated. Most potential MPF8 (20:80 chloroform: methanol ratio fraction) significantly enhanced free radicals and antibacterial activity. The best MIC (Minimum inhibitory concentration) of MPF8 was investigated against M. luteus and E.coli at 1 mg/ml concentration. However, against other bacteria the MIC ranged from 1 mg/ml to 3 mg/ml. The GC-MS analysis showed the presence of many biologically active compounds such as alcohols, flavonoids, aromatic compounds, aldehydes, terpenoids fatty acid methyl esters, and phenolics. Pentadecanoic acid occupied maximum (52 %) area in GC-MS profiling. MPF8 was assayed for in-vitro cytotoxicity by MTT assay which confirms its less cytotoxicity at lower concentration and also significant ROS determination against J774 and THP1 cell lines after 2 and 4 hours.

description: It has been shown that density of microvessels decreases in the left ventricular after myocardial infarction (MI). The change of angiogenic and angiostatic factors as the main factors in revascularisation after exercise training in area at risk is not determined yet in MI. Therefore, the aim of the present study was the effect of exercise training and L-arginine supplementation on area at risk angiogenesis in myocardial infarction rat. Four weeks after surgery (Left Anterior Descending Coronary artery Ligation), myocardial infarction rats were divided into 4 groups: Sedentary rats (Sed-MI); L-arginine supplementation (La-MI); Exercise training (Ex-MI) and Exercise + L-arginine (Ex+La). Exercise training (ET) lasted for 10 weeks at 17 m/min for 10–50 min day−1. Rats in the Larginine-treated groups drank water containing 4 % L-arginine. After ET and L-arginine supplementation, ventricular function was evaluated and angiogenic and angiostatic indices were measured at ~1 mm from the edge of scar tissue (area at risk). Statistical analysis revealed that gene expression of VEGF as an angiogenic factor, angiostatin as an angiostatic factor and caspase-3 at area at risk decrease significantly in response to exercise training compared to the sedentary group. The capillary and arteriolar density in the Ex groups were significantly higher than those of the Sed groups. Compared to the Ex-MI group, the Ex+La group showed a markedly increase in capillary to fiber ratio. No significant differences were found in infarct size among the four groups, but cardiac function increased in response to exercise. Exercise training increases revascularization at area at risk by reduction of angiostatin. L-arginine supplementation causes additional effects on exercise-induced angiogenesis by preventing more reduction of VEGF gene expression in response to exercise. These improvements, in turn, increase left ventricular systolic function and decrease mortality in myocardial infarction rats.

description: Reliable marketing opportunities in both interregional and international trade along with relatively low transportation [and transaction] costs are essential to profitability of wheat production. In this study we have investigated one aspect of the quality of marketing and trade opportunities in the Kazakh wheat sector, that is the extent and nature of integration among regional wheat markets. We applied threshold cointegration technique to assess the co-movement between time series of elevator prices at three grain-trading (and producing) spots in the northern and central parts of the country. Results suggest that markets of two northern grain trading spots (Petropavlovsk and Kokshetau) are closely connected with each other while their connection with Karaganda in central Kazakhstan is much weaker. Here, levelling out of price gaps through arbitrage trade only occurs after a threshold of considerable extent has been surpassed. ZUSAMMENFASSUNG Eine wichtige Voraussetzung für die Wirtschaftlichkeit der Getreideproduktion sind verlässliche Vermarktungswege, die interregionalen und internationalen Handel zu relativ geringen Transport- und Transaktionskosten zulassen. Die Studie behandelt die Integration regionaler Weizenmärkte miteinander und beleuchtet damit, wie reibungslos Getreidehandel zwischen diesen Regionen möglich ist. Mit Hilfe von Verfahren der threshold cointegration analysis werden Zusammenhänge in den Preisentwicklungen zwischen drei wichtigen Handelsplätzen in Nordund Zentralkasachstan untersucht. Die Märkte der beiden nördlichen Marktorte Petropavlovsk und Kokshetau stehen in enger Verbindung zueinander, während sie wesentlich unabhängiger von den Marktentwickungen im zentralkasachischen Karaganda sind. Ein Ausgleich von Preisunterschieden zwischen den nördlichen Märkten und Karaganda findet erst statt, wenn diese Unterschiede einen beträchtlichen Schwellenwert (threshold) übersteigen.

description: Measurement outcomes provide data for a physical theory. Unless they are objective they support no objective scientific knowledge. So the outcome of a quantum measurement must be an objective physical fact. But recent arguments purport to show that if quantum theory is universally applicable then there is no such fact. This calls for a reappraisal of the notions of fact and objectivity. If quantum theory is universally applicable the facts about the physical world include a fact about each quantum measurement outcome. These physical facts lack an ideal kind of objectivity but their more modest objectivity is all that science needs.

Plug-and-play fault-tolerant and cyber-secure control: application to future distribution networks
Creators: name: Gallo, Alexander J
Publisher: name: Imperial College London
Year: 2020

description: In this thesis, we study the development of distributed cyber-attack detection methodologies with plug-and-play characteristics, to monitor large-scale cyber-physical systems, with a particular focus on future energy distribution networks. Over the last few decades, the penetration of distributed generation capacity in power networks has greatly increased, especially that of renewable energy sources. Thus, to maintain the required performance, novel methods for voltage and power regulation have been suggested. Given their scale and complexity, distributed control architectures have been proposed to regulate these networks, where the system is divided into subsystems, each with its own controller. These may then communicate to achieve global objectives. This has been in large part made possible by the advances in ICT and power electronics. Furthermore, the integration of cyber-resources in other systems has been a trend also in other critical systems. The increasing number of cyber-physical systems, however, implies the possibility of malicious agents interfering with the operations of critical infrastructure, thus causing significant disruptions, as attested by some high profile cases in recent years. Moving from this motivation, it is the primary objective of this thesis to define distributed cyber-attack detection architectures capable of detecting the presence of malicious agents: drawing upon a distributed control architecture for DC microgrids as a motivating example, we suppose that attacks may penetrate the communication network included between subsystem controllers to achieve current sharing. Moreover, we endow these distributed diagnosers with plug-and-play capabilities, i.e. the ability of automatically being reconfigured if the system changes its configuration. These techniques are validated through simulation on DC microgrids, an energy distributed network where generation and consumption of electricity are colocated within a single node, and experimentally on a network of electric springs, a demand-side management technology capable of regulating the voltage and power quality over distribution networks.

description: We consider gauge theories based on abelian $p-$forms on real compact hyperbolic spaces. Using the zeta-function regularization method and the trace tensor kernel formula, we determine explicitly an expression for the vacuum energy (Casimir energy) corresponding to skew-symmetric tensor fields. It is shown that the topological component of the Casimir energy for co-exact forms on even-dimensional spaces, associated with the trivial character, is always negative. We infer on the possible cosmological consequences of this result.

The CSMT data challenge requires participants to identify whether a given piece of melody is generated by computer or is composed by human. The dataset is formed by two parts: development dataset and evaluation dataset. The development dataset contains only computer generated melodies whereas the evaluation dataset contain both computer generated melodies and human composed melodies. The aim of the dataset is to examine whether it is possible to distinguish computer generated melodies by learning the feature of generated melodies.

description: Sepsis is one of the major causes of death reported in intensive care units. Acute kidney injury (AKI) and hypotension are important in the pathogenesis and mortality of systemic inflammatory response (SIR). Sesamol delays mortality in sepsis; however, its effects on AKI and hypotension and the role of peroxisome proliferatoractivated receptor-γ (PPAR-γ) activation have not been established. We investigated the effect of sesamol on SIR in cecal ligation and puncture (CLP)-induced acute kidney injury and lipopolysaccharide (LPS)-induced hypotension in rats. Sesamol was subcutaneously injected 1 h after SIR. Renal function (BUN and CRE) and proinflammatory mediators interleukin (IL)-1β and IL-6 were increased after CLP. Tumor necrosis factor (TNF)-α, IL-1β, IL-10, and nitrite production were significantly increased 6 h after LPS-induced hypotension (mean arterial pressure was significantly decreased). Sesamol significantly inhibited BUN, CRE, IL-1β, IL-6, and nitrite after CLP-induced acute renal injury. In addition, sesamol increased mean arterial pressure and IL-10, inhibited TNF-α and IL-1β, but did not affect nitrite production in LPS-induced hypotension. Sesamol increased PPAR-γ in the leucocytes and peritoneal macrophages in LPS-induced SIR. We conclude that sesamol regulates leucocyte and macrophage PPAR-γ-associated systemic cytokines expression, thereby ameliorates acute kidney injury and hypotension in rats.

description: In this work, we present a lightweight pipeline for robust behavioral cloning of a human driver using end-to-end imitation learning. The proposed pipeline was employed to train and deploy three distinct driving behavior models onto a simulated vehicle. The training phase comprised of data collection, balancing, augmentation, preprocessing and training a neural network, following which, the trained model was deployed onto the ego vehicle to predict steering commands based on the feed from an onboard camera. A novel coupled control law was formulated to generate longitudinal control commands on-the-go based on the predicted steering angle and other parameters such as actual speed of the ego vehicle and the prescribed constraints for speed and steering. We analyzed computational efficiency of the pipeline and evaluated robustness of the trained models through exhaustive experimentation during the deployment phase. We also compared our approach against state-of-the-art implementation in order to comment on its validity.

description: Topological properties of native folds are obtained from statistical analysis of 160 low homology proteins covering the four structural classes. This is done analysing one, two and three-vertex joint distribution of quantities related to the corresponding network of amino acid residues. Emphasis on the amino acid residue hydrophobicity leads to the definition of their center of mass as vertices in this contact network model with interactions represented by edges. The network analysis helps us to interpret experimental results such as hydrophobic scales and fraction of buried accessible surface area in terms of the network connectivity. To explore the vertex type dependent correlations, we build a network of hydrophobic and polar vertices. This procedure presents the wiring diagram of the topological structure of globular proteins leading to the following attachment probabilities between hydrophobic-hydrophobic 0.424(5), hydrophobic-polar 0.419(2) and polar-polar 0.157(3) residues.

Οι ανθρώπινοι πόροι είναι οι πιο σημαντικοί πόροι ενός οργανισμού, στην απόδοση των οποίων εξαρτάται σε μεγάλο βαθμό και η επιτυχία και απόδοση ενός οργανισμού, ειδικότερα σε περιόδους κρίσεων (Armstrong, 2006, Johanson, 2009). Η προσέλκυση υποψήφιων εργαζόμενων για απασχόληση σε έναν οργανισμό εξαρτάται τόσο από εσωτερικούς- οργανωσιακούς, όσο και σε εξωτερικούς παράγοντες. Σε περιόδους κρίσεων και γενικότερης αβεβαιότητας, οι εργαζόμενοι κατά κύριο λόγο επιδιώκουν να εργαστούν σε οργανισμούς που διακρίνονται για τη συνέπεια και σταθερότητά τους μέσα στο χρόνο (Kernisky, 1997). Πιο συγκεκριμένα, η διπλωματική εργασία αποτελείται από το θεωρητικό μέρος, στο οποίο αναλύεται η έννοια του ανθρώπινου δυναμικού, η πολύτιμη σημασία της ορθής διαχείρισης του, καθώς και οι πηγές προσέλκυσης προσωπικού, όπως και οι παράγοντες που επηρεάζουν τη προσέλκυση προσωπικού. Επιπλέον, μελετώνται τα αίτια εμφάνισης της οικονομικής κρίσεως, όπως και η κατάσταση που επικρατεί στην Ευρωζώνη, αλλά και στην Ελλάδα, η αγορά εργασίας και οι προοπτικές για αύξηση της απασχόλησης, καθώς επίσης και οι προσλήψεις εργατικού δυναμικού από την Ευρωπαϊκή Ένωση σε ελληνικές επιχειρήσεις. Όσον αφορά το πρακτικό μέρος, αρχικά αναλύεται η μεθοδολογία της έρευνας, εξηγώντας και αιτιολογώντας την επιλογή της κάθε μεθόδου.

Stationary entanglement and nonlocality of two qubits or qutrits collectively interacting with the thermal environment: The role of Bell singlet state

description: We investigate the stationary entanglement and stationary nonlocality of two qubits collectively interacting with a common thermal environment. We assume two qubits are initially in Werner state or Werner-like state, and find that thermal environment can make two qubits become stationary nonlocality. The analytical relations among average thermal photon number of the environment, entanglement and nonlocality of two qubits are given in details. It is shown that the fraction of Bell singlet state plays a key role in the phenomenon that the common thermal reservoir can enhance the entanglement of two qubits. Moreover, we find that the collective decay of two qubits in a thermal reservoir at zero-temperature can generate a stationary maximally entangled mixed state if only the fraction of Bell singlet state in the initial state is not smaller than 2/3. It provides us a feasible way to prepare the maximally entangled mixed state in various physical systems such as the trapped ions, quantum dots or Josephson Junctions. For the case in which two qutrits collectively coupled with the thermal reservoir at zero-temperature, we find that the collective decay can induce the entanglement of two qutrits initially in the maximally mixed state. The collective decay of two qutrits can also induce distillable entanglement from the initial conjectured negative partial transpose bound entangled states.

description: Visualisation is often presented as a means of simplifying information and helping people understand complex data. In this paper we describe the design, development and evaluation of an interactive visualisation for spreadsheet formulae (EQUS). The work is justified on the grounds that these are widely used tools for significant numerical processing and modeling, yet the formula developed can be easily misunderstood. The development process was one of iterative refinement engaging an initial target audience of mid-teen learners, involving re-design and formative evaluation. The resulting visualisation techniques have been found to be broadly relevant to spreadsheet users beyond the initial target audience. EQUS has since been developed as fully integrated plug-in for MS Excel.

Gray oil, and Commiphora myrrha (Nees) Engl oil, against most common Candida spp. recovered from the human oral cavity. The essential oil samples were analyzed by GC-FID and GC/MS. The analysis showed that major essential oils’ components were ɑ–pinene (23.04 % and 31.84 %), limonene (45.62 %) and curzerene (34.65 %), respectively. Minimum inhibitory (MIC) and minimum fungicidal (MFC) concentrations were determined using a microdilution standardized technique. All tested Candida spp. clinical isolates and ATCC strains showed susceptibility to tested essential oils in a dose dependent manner. The strongest antifungal activity was shown by essential oil of B. carterii, sample 2; the average MIC values ranged from 1.25 to 1.34 mg/ml, and MFC values ranged from 2.50 to 3.75 mg/ml, depending on the fungus. This study supports the possible use of essential oils from the Bursecaceae family in reduction and elimination of Candida spp. populations in patients with oral cavity fungal infections.

Acute (96 hours) exposure and high concentrations of boric acid and borax increases % tail DNA and Olive tail moment. Genotoxicity was found for BA as concentration-dependent and BX as concentration and time dependent manner. In general, significant effects (P < 0,05) on both concentrations and exposure times were observed in experimental groups. DNA damage was highest at 96 h and 24 h for all BX and BA concentrations, respectively in peripheral blood of D. rerio. For the first time, our study demonstrates the effect of waterborne BA and BX exposure on genotoxicity at the molecular level, which may contribute to understanding the mechanism of boric acid and borax-induced genotoxicity in fish.

description: The prevalence of allergic rhinitis and atopic eczema is on the rise in recent decades. Many factors can be related to the development of these diseases. We aimed to investigate the association between socioeconomic status (SES), environmental risk factors and these conditions. In this study, the International Study of Asthma and Allergies in Childhood (ISAAC) questionnaire was translated and validated. Then it was used to determine the prevalence, severity and possible related factors for both diseases in 1904 schoolchildren aged 6-7 and 13-14 years from various regions of Tehran. The prevalence of rhinitis and eczema in the past year was 33.2 % and 8.2 %, respectively. The prevalence of rhinoconjunctivitis in the past year was 30 %. The risk factors such as birth order, nursery attendance, pet ownership, past allergic experiences as well as some SES factors were associated with both conditions. The prevalence of allergic rhinitis and atopic eczema was on the rise in comparison to the previous studies and SES as well as environmental factors are thought to be associated with the prevalence of these conditions.

description: Using the tensor Radon transform and related numerical methods, we study how bulk geometries can be explicitly reconstructed from boundary entanglement entropies in the specific case of $\mathrm{AdS}_3/\mathrm{CFT}_2$. We find that, given the boundary entanglement entropies of a $2$d CFT, this framework provides a quantitative measure that detects whether the bulk dual is geometric in the perturbative (near AdS) limit. In the case where a well-defined bulk geometry exists, we explicitly reconstruct the unique bulk metric tensor once a gauge choice is made. We then examine the emergent bulk geometries for static and dynamical scenarios in holography and in many-body systems. Apart from the physics results, our work demonstrates that numerical methods are feasible and effective in the study of bulk reconstruction in AdS/CFT.

description: We report experimental evidence of excitonic spin-splitting, in addition to the conventional Zeeman effect, produced by a combination of the Rashba spin-orbit interaction, Stark shift and charge screening. The electric-field-induced modulation of the spin-splitting are studied during the charging and discharging processes of p-type GaAs/AlAs double barrier resonant tunneling diodes (RTD) under applied bias and magnetic field. The abrupt changes in the photoluminescence, with the applied bias, provide information of the charge accumulation effects on the device.

description: Vortices in a Bose-Einstein condensate are modelled as spontaneously symmetry breaking minimum energy solutions of the time dependent Gross-Pitaevskii equation, using the method of constrained optimization. In a non-rotating axially symmetric trap, the core of a single vortex precesses around the trap center and, at the same time, the phase of its wave function shifts at a constant rate. The precession velocity, the speed of phase shift, and the distance between the vortex core and the trap center, depend continuously on the value of the conserved angular momentum that is carried by the entire condensate. In the case of a symmetric pair of identical vortices, the precession engages an emergent gauge field in their relative coordinate, with a flux that is equal to the ratio between the precession and shift velocities.

description: The root of Combretum dolichopetalum (Combreatacea) is used in ethnomedicine for the management of diabetes mellitus. Though some compounds have been isolated from it, the antidiabetic principles have not been identified. The present study was designed to evaluate the chemical constituents from the root of C. dolichopetalum with a view to identifying the antidiabetic principles. The constituents include the alkaloids, echinulin (1) and arestrictin B (2), the terpenoids, arjunolic acid (3) and 4'-dihydrophaseic acid (4) as well as the phenolic acids, ellagic acid (5) and 3, 4, 3'-tri-O-methylellagic acid (6). Twenty eight mice (in seven groups, n = 4) were made diabetic using alloxan monohydrate (i.p., 120 mg/kg) and treated orally with either the vehicle (control group), any of the constituents or glibenclamide (standard drug). The fasting blood glucose of the diabetic animals was monitored for nine hours. Results showed that all the chemical constituents (1-6) exhibited significant (p < 0.05) antidiabetic activity comparable to glibenclamide. The alkaloids exhibited the most profound antidiabetic activity. The present study has thus identified the antidiabetic principles of C. dolichopetalum root as echinulin, arestrictin B, arjunolic acid, 4'-dihydrophaseic acid, ellagic acid and 3, 4, 3'-tri-O-methylellagic acid. The study has further validated the ethnomedicinal use of the root of C. dolichopetalum in diabetes.

description: Presently Russia is experiencing the complicated process of transforming the economic system of central planning into a socially oriented market economy. Of great importance for the success of this process is the institutional reshaping of the agricultural sector, particularly the privatisation of land and assets. In this paper the procedure and the problems of privatising Russian agriculture are extensively discussed against the background of the unfavourable development of the Russian agricultural sector.

description: Reaumuria vermiculata is a xero-halophytic specie widely distributed in the south of Tunisia. In the current study, antioxidant, anti-inflammatory and anticancer activities of Reaumuria vermiculata shoot extracts as well as its phenolic compounds were investigated in different solvent extracts (hexane, dichloromethane, methanol and water). Results showed a strong antioxidant activity, using the ORAC method and a cell based-assay, in methanol extract as well as an important phenolic composition (117.12 mg GAE/g). Hexane and dichloromethane proved an interesting anticancer activity against A-549 lung carcinoma cells, with IC50 values of 17 and 23 μg/ml, respectively. Besides, dichloromethane extract displayed the utmost anti-inflammatory activity, inhibiting NO release over 100 % at 80 μg /ml in LPS-stimulated RAW 264.7. Taken together, these finding suggest that R. vermiculata exhibited an interesting biological activities which may be related to the phenolic composition of this plant. Moreover, the identification of phenolic compounds in R. vermiculata dichloromethane extract using RP-HPLC revealed that myricetin was the major molecule. These results allow us to propose R. vermiculata as a valuable source for bioactive and natural compounds exhibiting interesting biological capacities.

description: Empirical analysis of rural credit market failure has been of key scientific and political interest in recent years. The aim of this paper is to give an overview of various methods for measuring credit rationing of farms employed in the literature. Furthermore, based on a common analytical framework entailing a formal model of a credit rationed farm household, the methods are subjected to a comparative evaluation of their specific strengths or shortcomings. Six approaches are distinguished: measurement of loan transaction costs, analysis of qualitative information collected in interviews, analysis of quantitative information collected in interviews by using the credit limit concept, analysis of spill-over effects with regard to secondary credit sources, econometric household modelling, and the econometric analysis of dynamic investment decisions. The first approach defines credit rationing as the impossibility to take a loan due to prohibitively high, measurable transaction costs on loan markets, which is a price rationing mechanism. All other approaches at least implicitly define credit rationing as a persistent private excess demand in terms of a quantity restriction. The six approaches are more or less closely linked to the neo-classical efficiency concept. An explicit comparison with a first-best solution is impossible in the first three approaches, since they essentially rely on a subjective assessment of borrowers' access to credit, based on qualitative or quantitative indicators. The fifth and sixth approach allow a rigorous interpretation in the framework of neo-classical equilibrium theory. The fourth approach takes an intermediate position, since spill-over on segmented loan markets reveals a willingness to pay with regard to the supposedly less expensive but rationed primary source. Approaches are fairly data demanding in general, usually requiring specific data on loan transactions. Even so, most approaches are applicable to cross-sectional household data. Only dynamic modelling of investment decisions necessitates the availability of panel data, therefore restricting the applicability in low-income and transition countries. With the exception of the first, all methods surveyed might plausibly be used to empirically detect credit rationing.

description: Σκοπός της παρούσας έρευνας είναι τα μελετήσει τα πράσινα ομόλογα, δηλαδή τα ομολόγα που τα τελευταία έτη προωθούνται σημαντικά ως ένα μέσω για την ενίσχυση της χρηματοδότησης έργων με περιβαλλοντικά οφέλη. Η ταχεία ανάπτυξη της συγκεκριμένης αγοράς καθιστά επιβεβλημένη την μελέτη της επίδρασης των πράσινων ομολόγων στην αγορά και τις επενδύσεις. Τα πράσινα ομόλογα όχι μόνο παρέχουν ένα μέσο για την προώθηση των επενδύσεων, αλλά αποτελούν και ευκαιρία για την ανάληψη έργων προστιθέμενης αξίας, περιορίζοντας παράλληλα τις επιπτώσεις της επιχειρηματικής δράσης στο περιβάλλον. Ως εκ τούτου, η έκδοσή τους έχει αντίκτυπο πέρα από το περιβάλλον και στον πλούτο των μετόχων και στην εταιρική αξία. Οι συνεχείς προσπάθειες βελτίωσης του θεσμικού πλαισίου των πράσινων ομολόγων αν συνοδεύεται από το ενδιαφέρον της επενδυτικής αγοράς μπορεί να εξασφαλίσει σε μεγαλύτερο βαθμό την προσπάθεια περιβαλλοντικής αειφορίας. Με την παρούσα έρευνα επιδιώκεται η κατανόηση της αντίδρασης των επενδυτών στην έκδοση πράσινων ομολόγων από τις επιχειρήσεις. Η μεθοδολογική προσέγγιση που επιλέχθηκε είναι η μέθοδος της ανάλυσης γεγονότων ενώ για την διερεύνηση των χαρακτηριστικών των εταιρειών που καθορίζουν την απόδοση δημιουργήθηκε γραμμικό μοντέλο παλινδρόμησης. Το δείγμα της έρευνας ήταν 81 εκδόσεις πράσινων ομολόγων κυρίως εταιρειών με έδρα στην Ευρώπη από το 2013 έως και το 2020. Βασικό εύρημα της έρευνας ήταν ότι οι εκδόσεις πράσινων ομολόγων οδηγούν σε αύξηση των χρηματιστηριακών αποδόσεων των εταιρειών. Συγκεκριμένα 20 ημέρες μετά την έκδοση η υπερβάλλουσα απόδοση ήταν 0,4% ενώ για 10 ημέρες μετά η απόδοση ήταν 0,7%. Επίσης αύξηση των αποδόσεων παρατηρήθηκε και πριν την έκδοση, που αυξάνονταν όσο πλησίαζε η ημερομηνία έκδοσης. Διαπιστώνεται ότι οι επενδυτές εκλαμβάνουν θετικά την έκδοση πράσινων ομολόγων είτε γιατί αποτελεί ένα μέσο προαγωγής της περιβαλλοντικής αειφορίας είτε γιατί θεωρούν ότι θα βελτιώσει μελλοντικά τις αποδόσεις των εταιρειών. Σε κάθε περίπτωση τα συγκεκριμένα ευρήματα ενισχύουν τα κίνητρα των επιχειρήσεων για την πραγματοποίηση πράσινων επενδύσεων και χρηματοδότησής τους από πράσινα ομόλογα.
