description: This dissertation consists of four essays and aims to contribute to a better understanding of financial markets and investor behavior. The first three essays focus on the effects of the COVID-19 crisis, which constituted an exogenous shock to a firm’s future cash flows and thus led to market collapse. Given the dramatic downturn, the COVID-19 crisis presents an opportunity to examine how market participants evaluate the importance of certain firm characteristics for the firm’s ability to generate future cash flows and also how characteristics of countries and societies influence capital market outcomes. In Essay 1, we therefore provide evidence that societal trust and trust in the country’s government significantly reduced stock market volatility in reaction to COVID-19 case announcements during the crisis period. We relate this result to trust alleviating uncertainty among investors about the country’s ability to overcome the crisis. In Essay 2, we show firms which use their resources more efficiently to experience higher returns during the crisis. We argue that the outperformance of efficient firms relates to these firms having less risky expected cash flows and thus a lower risk of default, which is consistent with the view in Frijns et al. (2012). In Essay 3, we study whether having better-quality investor relations (IR) helps to alleviate information frictions among market participants and is thus valuable for firms. The results suggest that firms with better-quality IR experienced higher returns, retained more incumbent institutional investors, and also attracted more new institutional investors during the crisis period. Finally, Essay 5 moves away from the topic of the COVID-19 crisis, but it also contributes to a better understanding of financial markets and investor behavior. In this last essay, we examine whether institutional investors view operational leanness as a competitive advantage resulting in higher expected cash flows. The results provide evidence that institutional investors generally appear to prefer lean firms since the reduction in operational slack is associated with a cost advantage. However, the results also suggest that institution types differ substantially in how they evaluate operational leanness because of market and information frictions.

description: We present calculations on the deformation of two- and three-layer electret systems. The electrical field is coupled with the stress-strain equations by means of the Maxwell stress tensor. In the simulations, two-phase systems are considered, and intrinsic relative dielectric permittivity and Young's modulus of the phases are altered. The numerically calculated electro-mechanical activity is compared to an analytical expression. Simulations are performed on two- and three-layer systems. Various parameters in the model are systematically varied and their influence on the resulting piezoelectricity is estimated. In three-layer systems with bipolar charge, the piezoelectric coefficients exhibit a strong dependence on the elastic moduli of the phases. However, with mono-polar charge, there is no significant piezoelectric effect. A two-dimensional simulation illustrated that higher piezoelectricity coefficients can be obtained for non-uniform surface charges and low Poisson's ratio of phases. Irregular structures considered exhibit low piezoelectric activity compared to two-layer structures.

description: Potentially toxic elements and particulate matter (PM) in the ecosystem are regarded as extremely hazardous because of their persistence, toxicity and bioaccumulative characteristics. Therefore, present study was conducted to estimate the ecological and human health risks of potentially toxic elements (Cu, Mn, Pb, Cd and Ni) and particle pollution (TSP, PM10 and PM2.5) at 2 and 60 m roadside distance from 15 different sites at dust polluted megacity of Pakistan. The AQI assessments suggested that the majority of sites were found unhealthy for sensitive at 2 and 60 m roadside distance, which reveals that that quality of road pavement and streets are far below than the required standards resulting huge quantity of dust particles suspended in air by natural and anthropogenic activities. The maximum geo-accumulation index (Igeo) values (1.47 and 0.52) and pollution index (PI) values (4.18 and 2.15) were observed for Ni at 2 and 60 m distance away from the muddy edge of the roads. Similarly, maximum contamination factor (CF) values (24.5 and 94.5) and ecological risk index (ERI) values (4.11 and 3.15) were found for Cd at 2 and 60 m. The Igeo and PI indicated that the road dust at a distance of 2 m was relatively more contaminated as compared to 60 m roadside distance. Highest cancer risk (CR) values (2.33 adult and 10.9 for children) were observed for Pb at 2 m, while highest CR values (1.21 for adult and 5.67 for children) at 60 m distance. No probable health risk was observed as the total hazard index (HIexp) of all potentially toxic elements was <1. However, children were appeared to be more susceptible to potentially toxic elements. Based on the results, we believe that the exponential increase in traffic load and industries have aggravated the pollution level and it is expected to be increased in the future.

description: We have carried out Monte Carlo simulations of zig-zag shaped molecules where the the molecules is composed of three rigidly linked hard spherocylinder arranged in a zigzag fashion. By varying zigzag angle we have mapped out the whole phase diagram as a function of pressure, molecular density and zigzag angle $Ψ$. For $Ψ$ between $35^0$ and $80^0$ our model simulation exhibits SmC phase. This is the first conclusive evidence where steric interaction arising out of molecular shape alone induce the occurrence of SmC phase for a wide range of zigzag angle. For smaller $Ψ$, a transition from tilted crystal (XT) to nontlted crystal is observed.

description: Myoglobin (Mb), oxygen-binding heme-protein retrieved primarily in muscles, is a local oxygen reservoir providing to oxygen when oxygen delivery is insufficient during catabolism. Furthermore, Mb structure is studied as example of molecular evolution for its ability to respond to environmental pressures and adapt to it through few amino acid substitutions. Here, in order to explore the structure–function–dynamics relationships of Eurasian woodcock chicken and ostrich Mbs we have applied an integrated approach in which spectroscopic and biochemical data have been coupled to computational techniques as structural modelling and molecular dynamics simulations. The primary structure of E. woodcock Mb, reveals the presence of 3 (i.e. Q34H, E44D and V66A) and 10 (i.e. A19T, E27A, V28I, K50T, D53E, G57A, D60E, N81K, S84A and A120S) amino acid substitutions respect to chicken and ostrich Mbs, respectively. Although the high amino acid sequence identity, E. woodcock Mb displays a higher autoxidation rate than chicken and ostrich Mb, despite of a similar melting temperature (Tm ∼ 358 K). Yet, the 3D structural models validated by using experimental data indicate that the three Mbs adopt an almost identical three-dimensional structure conserving the typical secondary and tertiary structural organization. Interestingly, dynamics data reveal that the E. woodcock Mb exhibits greater internal motions than either chicken or ostrich Mbs. Overall, our study demonstrates that in Mbs the functional properties are significantly driven by the protein dynamic peculiarities, which in turn depend on the amino acid composition of the region located in proximity of the pathways for the gas ligands.

description: The purpose of this study is to provide basic informations for promoting agricultural cooperations in Northeast Asia. This study tried to enlighten the complementary or competitive relationships between member countries with regard to the agricultural trade. Mutual complementarity and export competitiveness between China, Japan and Korea depend on products. In general, however, complementarity seems to be stronger than export competitiveness in agricultural trade between China and Japan. On the other hand, export competitiveness is stronger in the Korea-China trade. Both appeared to be evident in the trade between Korea and Japan. In the unlimited global competition, Northeast Asian agriculture can survive through regional intra-industry division of labor and trade according to their respective comparative advantage.
Statistical modelling of rainfall enhancement

Year: 2024

description: Non-stationary spatial variation makes it difficult to establish real-time areas of controland effect in weather modification. Non-stationary temporal variation makes the comparisonof long-term averages from limited climatic records open to question. Here we describe astatistical methodology which addresses both problems explicitly, in a trial of a ground-basedionization technology known as Atlant, and which could be applied to other weathermodification technologies more generally. The approach adopted here is based on a statisticalmodel for daily rainfall that achieves a high level of real-time control by the inclusion of bothspatial and temporal components. In particular, it makes use of daily gauge level rainfall data,orographic and daily meteorological covariates, as well as dynamically defined downwindareas, to model the impact of Atlant operation on rainfall. Subject to some important caveats,this type of dynamic control demonstrates a clear rainfall enhancement signal at both a simpleobservational level and when a spatial random effects model is used to control for covariates.Rainfall downwind of the Atlant test site was 15% higher than rainfall in the control(crosswind or upwind) areas. Based on these results, randomized trials with multiple sites arecurrently being conducted in the same area.
Protoneutron Star Winds

description: Neutrino-driven winds are thought to accompany the Kelvin-Helmholtz cooling phase of nascent protoneutron stars in the first seconds after a core-collapse supernova. These outflows are a likely candidate as the astrophysical site for rapid neutron-capture nucleosynthesis (the r-process). In this chapter we review the physics of protoneutron star winds and assess their potential as a site for the production of the heavy r-process nuclides. We show that spherical transonic protoneutron star winds do not produce robust $r$-process nucleosynthesis for `canonical' neutron stars with gravitational masses of 1.4 M_sun and coordinate radii of 10 km. We further speculate on and review some aspects of neutrino-driven winds from protoneutron stars with strong magnetic fields.

description: The main purpose of this paper is to review the possibilities for introducing farmland banking system as a new farmland management system and a few policy issues surrounding it. The reasons why the introduction of farmland banking system is necessary can be summarized as follows : (1) Korean government should take a measure to stabilize the farmland market, (2) it should make the rice industry competitive by improving the existing farmsize through ‘farmsize increasing projects’ and restructuring the industry, and (3) it should cope with the diverse and increasing demand for farmland to empower and enterprise rural community etc. There are several policy issues for introducing new system : fundraising, taking legal steps for realizing new programs, harmonizing with other programs, reforming the practicing systems of the related policy programs(for example, farmsize increasing project), etc.

description: The major purposes of this paper are 1) to explore the major determinants that affect the adoption of environmental agriculture in farming households, and 2) to investigate the regional differences for this indicator. We utilized Korea Agricultural Survey Data, which has not been fully utilized before. The present study pay particular attention to the hierarchical structure of the data and spatial units when applying our statistical models in our empirical settings. The present study apply multi-level logit models that can incorporates diverse spatial heterogeneities as well as individual differences. We found that there are big differences among regions that apply environmental agriculture. The present study also found that while education is positively associated with the adoption of environmental agriculture at the individual level, farm households with higher level education are less likely to adopt environmental agriculture at the regional level. Based on the findings of this study, the present study concludes with introducing several policy implications and future studies for the prosperity of Korean farming households and rural societies.

description: Trypanothione reductase of Leishmania donovani is a flavin adenine dinucleotide containing homodimeric protein essential for parasite survival. The flavoenzyme utilizes nicotinamide adenine dinucleotide phosphate in the reaction to convert oxidized trypanothione to reduced trypanothione which is further used up by tryparedoxin/tryparedoxin peroxidase system to neutralize the reactive oxygen species generated by the macrophages. Some of the drugs previously reported against the disease include sodium stibogluconate, miltefosine and amphotericin B. However, due to the resistance and toxicity problem associated with these molecules, there is an urgent need to develop new drugs against L. donovani. Trypanothione reductase of L. donovani is one such essential target whose inhibition could lead to a decline in parasite growth. In this work, we have performed a computational studies using Maybridge library of chemical compounds to identify potential inhibitors of Trypanothione reductase of L. donovani. Structure-based virtual screening method in combination with molecular docking was employed to identify and prioritize 30 compounds which were further subjected to molecular dynamics simulation. Ten compounds which showed stable ligand root-mean-square deviation plot, c-alpha backbone and root-mean-square fluctuation were considered for trypanothione reductase inhibition assay and subsequent inhibition studies of parasite growth. Enzyme inhibition assay resulted in shortlisting of four compounds that were found to inhibit Trypanothione reductase of L. donovani. Subsequently, the anti-leishmanial screening highlighted one compound as the potential anti-leishmanial agent, with IC50 value of 15.2 µM, that can be further optimised with medicinal chemistry efforts to improve its activity.

description: The purpose of this study is to explore the socio-economic characteristics and their policy implications of agro-touristic farm households in rural Korea. The data were collected by questionnaire and obtained from 104 agro-touristic farmers and 104 village people in twenty two rural villages from April 20, 2002 to November 21, 2002 and analyzed. With the research results, it has been shown that, even Korean government's efforts to diversify farm management somewhat contributed to improve small farms' income, it was difficult for farm householders to grow their businesses continuously due to the following restrictions; 1) the age of farm managers were old to expand their new businesses, 2) the pluriactivities of agro-touristic farm households were not enough to supplement their income, and 3) they were not so much willing to take the risk from expanding the scale of agro-touristic business. As such, we suggested that the governments' policy makers consider to establish the policy goal of the rural tourism projects reasonably.

subject: Rice production costs

description: China is the largest rice production country in the world that produced 120 million metric tonnage of rice(32% of world rice products; polished rice) in 2002/2003. She is also very competitive in terms of the production cost on the basis of abundant labor and low wage. The production cost per kilogram of rice in China is 150 Korean won in 2001, which is six times lower than that of Korea. Especially, agricultural productivity has increased dramatically since the expansion of farm business sale(per farm household) and the transformation from state enterprises to family farm system in 1979. Such rapid growth of Chinese rice production will be a menacing factor to the Korean agriculture that is about to open its domestic agricultural market. This paper is to get the implication on Korean rice sector by reviewing current situation of Chinese rice production cost.

description: We consider the Hele-Shaw flow that arises from injection of two-dimensional fluid into a point of a curved surface. The resulting fluid domains have and are more or less determined implicitly by a mean value property for harmonic functions. We improve on the results of Hedenmalm and Shimorin \cite{HS} and obtain essentially the same conclusions while imposing a weaker curvature condition on the surface. Incidentally, the curvature condition is the same as the one that appears in a recent paper of Hedenmalm and Perdomo, where the problem of finding smooth area minimizing surfaces for a given curvature form under a natural normalizing condition was considered. Probably there are deep reasons behind this coincidence.

description: POU domain class 2 homebox 1 or POU2F1 is broadly known as an important transcription factor. Due to its association with different types of malignancies, POU2F1 became one of the key factors in pancancer analysis. However, in spite of considering this protein as a potential drug target, none of the drug targeting POU2F1 has been designed as of yet due to the extreme structural flexibility of this protein. In this article, we have proposed a three-level comprehensive framework for understanding the structural conservation and co-variation of POU2F1. First, a gene regulatory network based on the normal and pathological functions of POU2F1 has been created for better understanding the strong association between POU2F1 deregulation and cancers. After that, based on the evolutionary sequence space analysis, the comparative sequence dynamics of the protein members of POU domain family has been studied mostly between non-human and human species. Subsequently, the reciprocity effect of the residual co-variation has been identified through direct coupling analysis. Along with that, the structure of POU2F1 has been analyzed depending on quality assessment and normal mode-based structure network. Comparing the sequence and structure space information, the most significant set of residues viz., 3, 9, 13, 17, 20, 21, 28, 35, and 36 have been identified as structural facet for function. This study demonstrates that the structural malleability of POU2F1 serves as one of the prime reason behind its functional multiplicity in terms of protein moonlighting.

First, it is shown that the Jaffe metric can be displayed graphically using the biplot, a graphical display of a two-dimensional approximation to any multidimensional matrix. Second, it is illustrated that since the data used to produce the Jaffe metric is constrained within the simplex (i.e. shares add up to one), then a theoretically superior metric satisfying the basic axioms of technological proximity measures in this sample space is the Aitchison distance measure, a metric based on log-ratios of shares. The findings of the paper using agricultural research and development spillover potential for Southern African countries show that the Jaffe metric overestimates the technological proximity across countries as compared to the proposed Aitchison measure.

description: This paper outlined the environment impact assessment (EIA) in the Sihwa project, and raised some issues. After EIA process, some key changes were introduced in the area; for example, more than six hundred hectares are newly allotted for wetland to help conserve natural ecosystem. The most salient contribution of EIA is its clear indication that the sustainable agriculture should be the way of farming on the newly created agricultural lands. However, it is argued that a new comprehensive environmental impact assessment is necessary which incorporates all development plans and projects in the Sihwa area. The environment impact statement was prepared under the assumption that the project would be implemented, without seriously considering no-action alternative. The project should be validated socially and economically, by implementing social impact assessment.

description: This work investigated the ecological and health hazards caused by heavy metals present in urban street dust of Radom (Poland). The objectives of this study were to improve the estimation of exposure doses of toxic metals based on their distribution patterns in street dusts and to assess the noncarcinogenic health risk for the residents. Zinc (Zn), manganese (Mn), and lead (Pb) were mainly associated with the reducible fraction, copper (Cu) with the oxidizable fraction, and iron (Fe), nickel (Ni), and chromium (Cr) with the residual fraction. The contents of short-term and long-term labile fractions of the metals were used to assess a direct health risk, a potential health risk and an overall human health risk. The level of the overall risk quantified by the cumulative total labile fraction-HI (tlf-HIc): 3.91E-01 (children) and 3.85E-02 (adults) was lower than the safety limit of unity. The metal that contributed the most to the overall health risk was Pb: 34% (children) and 31% (adults), while Zn and Ni had the least contribution (3% and 2% for both children and adults). It was shown that the risk assessment based on the pseudo-total content of metals can overestimate the health risk by nearly two times when compared to the assessments based on the total content of labile fractions.

description: In the past decades, it was recognized that quantum chaos, which is essential for the emergence of statistical mechanics and thermodynamics, manifests itself in the effective description of the eigenstates of chaotic Hamiltonians through random matrix ensembles and the eigenstate thermalization hypothesis. Standard measures of chaos in quantum many-body systems are level statistics and the spectral form factor. In this work, we show that the norm of the adiabatic gauge potential, the generator of adiabatic deformations between eigenstates, serves as a much more sensitive measure of quantum chaos. We are able to detect transitions from non-ergodic to ergodic behavior at perturbation strengths orders of magnitude smaller than those required for standard measures. Using this alternative probe in two generic classes of spin chains, we show that the chaotic threshold decreases exponentially with system size and that one can immediately detect integrability-breaking (chaotic) perturbations by analyzing infinitesimal perturbations even at the integrable point. In some cases, small integrability-breaking is shown to lead to anomalously slow relaxation of the system, exponentially long in system size.

Ειδικότερα, τα τραπεζικά ιδρύματα δύνανται να ακολουθήσουν είτε την οδό του Κώδικα Πολιτικής Δικονομίας (ΚΠολΔ) είτε την οδό του νομοθετικού διατάγματος 17.7/13.8.1923, το οποίο διατηρήθηκε σε ισχύ και μετά την εισαγωγή του Αστικού Κώδικα (ΑΚ) και του ΚΠολΔ και το οποίο προτάσσει μια απλούστερη και ταχύτερη διαδικασία από αυτήν του κοινού δικαίου. Συγκεκριμένα, στην παρούσα εργασία αναλύεται το πεδίο εφαρμογής του Νομοθετικού Διατάγματος καθώς και η ιδιόμορφη διαδικασία εμπράγματης εξασφάλισης και εκτέλεσης των τραπεζών, τα οποία περιγράφονται σε παράλληλη σύγκριση με τον ΚΠολΔ, μνημονεύονται δε οι βασικές διαφορές τους, όπως η μη ύπαρξη εκτελεστού τίτλου κατά το άρθρο 904 ΚΠολΔ, οι ιδιαιτερότητες της κατάσχεσης, του πλειστηριασμού και τη καταβολής του πλειστηριάσματος. Περαιτέρω, γίνεται ειδική μνεία στη διαδικασία ενεχύρασης απαιτήσεων του οφειλέτη κατά τρίτου και στις περιπτώσεις κατάσχεσης τραπεζικής θυρίδας και τραπεζικών λογαριασμών, ζητήματα που επί σειρά ετών διχάζουν τον νομικό κόσμο. Τέλος, παρουσιάζεται το φαινόμενο των εισπρακτικών εταιριών, οι οποίες έχουν έρθει στο προσκήνιο τα τελευταία χρόνια και έχουν αποτελέσει αντικείμενο έντονης κριτικής.
description: The object of the work is the enforcement procedure followed by the banks in order to satisfy their financial claims. In particular, banking institutions may follow either the route of the Code of Civil Procedure (CCP) or the route of the Legislative decree 17.7/13.8.1923, which was maintained in force after the introduction of the Civil Code (CC) and CCP and sets a simpler and faster procedure than that of common law. More specifically, in the study is analyzed the scope of the Legislative Decree as well as the peculiar process of bank guarantee and enforcement which are described in comparison with the procedure of the CCP and are referred their main differences, like the absence of the enforceable instrument according to the Article 904 of CCP, the specificities of the attachment, the auction and the payment of the auction proceeds. Furthermore, special reference is made to the procedure of pledging on debtor's claims against a third party and to the attachment of bank vaults and bank accounts, issues that have divided the legal world for many years. Finally, the phenomenon of collection agency companies, which has come to the fore in recent years and has been the subject of intense criticism, is presented.

Food Security and Poverty

description: This paper reviews agricultural and food security performances of developing countries after the Uruguay Round. In particular, issues and trends relevant to the interests of the low income food deficit and the net food importing countries are examined as the world prepares for further trade negotiations. The paper attempts to answer several questions, including: How has food security in the low income countries been affected over the past ten years? Are agricultural policies evolving in ways that take advantage of emerging trade opportunities? Despite the gains in global and national food availability, food security remains an especially persistent and elusive development problem. The late 1990s food insecurity data are worrisome, with emerging signs of uneven and slowing progress. Most of the recent food security problems are due to food shortages caused by civil unrest, wars and drought ' age old problems that endure today.

description: Exposure to mercury (Hg), especially methylmercury (MeHg), through the consumption of seafood is a major public health concern. St. Vincent & the Grenadines (Eastern Caribbean) supports two related whaling operations, which produce food from cetaceans for human consumption. Recent data suggest that Hg concentrations in cetacean tissue samples exceed recommended consumption limits. Our objective was to determine the role of cetacean-based food products in the diet of the Vincentian population as a proxy for exposure to MeHg using interview surveys (n = 921). Based upon provisional tolerable weekly intake (PTWI) guidelines for MeHg from the Food and Agricultural Organization (FAO) and the World Health Organization (WHO), we determined safe weekly consumption amounts for specific cetacean-based food products, based upon reported consumption patterns. We found cetacean-based food products to be included in the diet of 77.4% of respondents. Respondents’ gender and geographical home region are the most important factors influencing cetacean consumption. Frequency and amount of consumption vary, but generally exceed calculated safe weekly limits. The consumption of cetacean-based food products may represent a public health risk, as a large portion of the population may be exposed to high MeHg concentrations.
