Ownership, Multiple Blockholders and Performance: A study of the Indonesian Banking Industry
Creators: name: Chalid, Dony Abdul <1979>

Subjects: SECS-P/08 Economia e gestione delle imprese

description: The objective of this study is to provide empirical evidence on how ownership structure and owner’s identity affect performance, in the banking industry by using a panel of Indonesia banks over the period 2000–2009. Firstly, we analysed the impact of the presence of multiple blockholders on bank ownership structure and performance. Building on multiple agency and principal-principal theories, we investigated whether the presence and shares dispersion across blockholders with different identities (i.e. central and regional government; families; foreign banks and financial institutions) affected bank performance, in terms of profitability and efficiency. We found that the number of blockholders has a negative effect on banks’ performance, while blockholders’ concentration has a positive effect. Moreover, we observed that the dispersion of ownership across different types of blockholders has a negative effect on banks’ performance. We interpret such results as evidence that, when heterogeneous blockholders are present, the disadvantage from conflicts of interests between blockholders seems to outweigh the advantage of the increase in additional monitoring by additional blockholder.
Secondly, we conducted a joint analysis of the static, selection, and dynamic effects of different types of ownership on banks’ performance. We found that regional banks and foreign banks have a higher profitability and efficiency as compared to domestic private banks. In the short-run, foreign acquisitions and domestic M&As reduce the level of overhead costs, while in the long-run they increase the Net Interest Margin (NIM). Further, we analysed NIM determinants, to asses the impact of ownership on bank business orientation. Our findings lend support to our prediction that the NIM determinants differs accordingly to the type of bank ownership. We also observed that banks that experienced changes in ownership, such as foreign-acquired banks, manifest different interest margin determinants with respect to domestic or foreign banks that did not experience ownership rearrangements.
Optimized water distribution network design
Creators: name: Smirfitt, Gary Robert
Publisher: name: University of British Columbia
Year: 2010

description: This thesis describes a study of two approaches to the design of water distribution networks to meet specified demands at minimum cost. One method is based on an incremental increase technique which first examines all possible "one-size" pipe increases in the network, then based on a benefit/cost analysis a decision is made on which pipe to increase one diameter size. The second approach utilizes a computerized linear programming technique to rapidly converge on an optimal network design. Both techniques rely on the use of an effective computerized network analysis program. It was found after studying several networks that the incremental increase technique is operational for any size of network. However, computer costs quickly become a limiting factor in the usefulness of this approach. The linear programming based technique was considerably less costly but did not prove itself to be fully capable of optimizing large networks in its present developmental state.

description: Nel 1997 venne isolata una popolazione cellulare con caratteristiche appartenenti a cellule endoteliali mature e a cellule progenitrici ; le cellule appartenenti a queste popolazione furono denominate EPCs  (cellule endoteliali progenitrici circolanti) e fu messa in evidenza la loro capacità  di dare origine a vasculogenesi postnatale.  Lo scopo dello studio è stata la caratterizzazione di tale popolazione cellulare in termini biologici e la valutazione delle differenze delle EPCs in soggetti sani e nefropatici in emodialisi.  È stata infine valutata l’eventuale capacità della Vitamina D di influenzare le capacità delle Late EPCs in termini di formazione di colonie in vitro e di attività anticalcifica in soggetti in insufficienza renale cronica.

description: In the atomic force microscope, the nanoscale force topography of even complex surface superstructures is extracted by the changing vibration frequency of a scanning tip. An alternative dissipation topography with similar or even better contrast has been demonstrated recently by mapping the (x,y)-dependent tip damping but the detailed damping mechanism is still unknown. Here we identify two different tip dissipation mechanisms: local mechanical softness and hysteresis. Motivated by recent data, we describe both of them in a onedimensional model of Moire' superstructures of incommensurate overlayers. Local softness at "soliton" defects yields a dissipation contrast that can be much larger than the corresponding density or corrugation contrast. At realistically low vibration frequencies, however, a much stronger and more effective dissipation is caused by the tip-induced nonlinear jumping of the soliton, naturally developing bistability and hysteresis. Signatures of this mechanism are proposed for experimental identification.

Comparison between analytical and numerical methods for the assessment of masonry arch bridges: Case study of Clemente Bridge on Savio river

Subjects: ICAR/08 Scienza delle costruzioni

description: This research has focused on the study of the behavior and of the collapse of masonry arch bridges. The latest decades have seen an increasing interest in this structural type, that is still present and in use, despite the passage of time and the variation of the transport means. Several strategies have been developed during the time to simulate the response of this type of structures, although even today there is no generally accepted standard one for assessment of masonry arch bridges.
The aim of this thesis is to compare the principal analytical and numerical methods existing in literature on case studies, trying to highlight values and weaknesses. The methods taken in exam are
mainly three: i) the Thrust Line Analysis Method; ii) the Mechanism Method; iii) the Finite Element Methods. The Thrust Line Analysis Method and the Mechanism Method are analytical methods and derived from two of the fundamental theorems of the Plastic Analysis, while the Finite Element Method is a numerical method, that uses different strategies of discretization to analyze the
structure. Every method is applied to the case study through computer-based representations, that allow a friendly-use application of the principles explained. A particular closed-form approach based on an elasto-plastic material model and developed by some Belgian researchers is also studied.
To compare the three methods, two different case study have been analyzed: i) a generic masonry arch bridge with a single span; ii) a real masonry arch bridge, the Clemente Bridge, built on Savio River in Cesena. In the analyses performed, all the models are two-dimensional in order to have results comparable between the different methods taken in exam. The different methods have been compared with each other in terms of collapse load and of hinge positions.

description: We present an interferometric pump-probe technique for the characterization of attosecond electron wave packets (WPs) that uses a free WP as a reference to measure a bound WP. We demonstrate our method by exciting helium atoms using an attosecond pulse with a bandwidth centered near the ionization threshold, thus creating both a bound and a free WP simultaneously. After a variable delay, the bound WP is ionized by a few-cycle infrared laser precisely synchronized to the original attosecond pulse. By measuring the delay-dependent photoelectron spectrum we obtain an interferogram that contains both quantum beats as well as multi-path interference. Analysis of the interferogram allows us to determine the bound WP components with a spectral resolution much better than the inverse of the attosecond pulse duration.

description: In many applications we are required to increase the deployment of a distributed monitoring system on an evolving network. In this paper we present a new method for finding candidate locations for additional deployment in the network. This method is based on the Group Betweenness Centrality (GBC) measure that is used to estimate the influence of a group of nodes over the information flow in the network. The new method assists in finding the location of k additional monitors in the evolving network, such that the portion of additional traffic covered is at least (1-1/e) of the optimal.

description: The chemical compatibility between carbon free olivine-LiNiPO₄ thin films used as cathode material and LiPF₆/DMC/FEC/0.2%-TMB liquid electrolyte was studied by soft-photoelectron spectroscopy, Ni L- and O K- XANES combined with electrochemical experiments. The stability of the electrolyte-electrode interface at a high charging potential strongly depends on the temperature of LiNiPO₄ preparation. For the films grown at 740°C, the chemical composition of the interface is not changed even at a charging potential of 5.2 V, whereas the electrolyte-electrode interface of LiNiPO₄ grown at lower temperatures (675°C) decomposes at 5.1 V, involving the cathode material in the chemical reaction.

description: Everyone is aware of the existence of personality, but no one is aware of what it is. It determines the number of key qualities as well as how people connect. A person's personality is made up of a variety of characteristics. Thus, this investigates the impact of personality traits on the academic performance of senior high school students from private and public schools in Bulacan, Philippines. The study's findings revealed that the students' "Big Five" personality traits were at an extreme level. Similarly, the results indicate that the students are very creative, focused on overcoming new obstacles, pay attention to detail, enjoy being the center of attention, enjoy meeting new people, and have empathy and care for others amidst the COVID-19 pandemic. Additionally, the students are agitated, concerned about a number of topics, and worried about their surroundings. In addition, the null hypothesis was evaluated at the 0.05 alpha level of significance to see if personality affected students' academic achievement. The calculated multiple regression analysis results demonstrated that personality factors have no significant impact on student's academic performance.

The (re)Introduction of Nubia and Ethiopia to Europe during the crusading
      era, c.1100-c.1400
Creators: name: Simmons, Adam
Publisher: name: Lancaster University
Year: 2019

description: This thesis analyses the exchange of knowledge regarding the African
      kingdoms of Nubia and Ethiopia between the wider Eastern Mediterranean and
      Europe. Whilst employing a varied linguistic (Latin, French, Italian,
      Spanish, Greek, Old Nubian, Arabic, and Gəʿəz) and theoretical (e.g.
      Network Analysis) approach, this thesis traces how such knowledge
      circulated and was, in turn, utilised for specific purposes. It argues
      that the onset of the Crusades formed the catalyst for the subsequent
      expansion of geographical knowledge following a period of centuries-long
      stagnation despite the expansive knowledge networks of Late Antiquity.
      Section One (Chs. I, II, III) (re)introduces Ethiopians and Nubians into
      European thought following their period of anonymity in the latter
      centuries of the first millennium, tracing the foundations of ancient
      knowledge at the beginning of the millennium and how this differed to that
      known during the early crusading years at the turn of the twelfth century.
      With the creation of the Crusader States, Section Two (Chs. IV, V, VI)
      analyses the development of knowledge as a result of increased
      undocumented dissemination, principally via undocumented networks and
      communal knowledge in the Holy Land. Finally, Section Three (Chs. VII,
      VIII) explores how this new information was utilised, particularly in the
      search for allies in the defence of the Holy Land. Through the growing
      early information of Prester John, which this thesis argues developed
      distinctly between the African Prester Johns of Nubia and Ethiopia,
      Europeans actively sought to communicate with the kingdoms. Ultimately,
      Europeans hoped for a military alliance and both kingdoms found themselves
      in varying crusade treatises following the fall of the Crusader States.
      Above all, this thesis argues that the post1402 interactions between
      Ethiopia and Europe were actually founded upon earlier notions of Nubia,
      which following the kingdom’s demise in the fourteenth century, forced
      European attentions to turn to Ethiopia instead.

description: We analyze the mechanical deformations that are required to create uniform pseudomagnetic fields in graphene. It is shown that, if a ribbon is bent in-plane into a circular arc, this can lead to fields exceeding 10T, which is sufficient for the observation of pseudo-Landau quantization. The arc geometry is simpler than those suggested previously and, in our opinion, has much better chances to be realized experimentally soon. The effects of a scalar potential induced by dilatation in this geometry is shown to be negligible.

description: This work addresses the problem of Question Answering (QA) on handwritten document collections. Unlike typical QA and Visual Question Answering (VQA) formulations where the answer is a short text, we aim to locate a document snippet where the answer lies. The proposed approach works without recognizing the text in the documents. We argue that the recognition-free approach is suitable for handwritten documents and historical collections where robust text recognition is often difficult. At the same time, for human users, document image snippets containing answers act as a valid alternative to textual answers. The proposed approach uses an off-the-shelf deep embedding network which can project both textual words and word images into a common sub-space. This embedding bridges the textual and visual domains and helps us retrieve document snippets that potentially answer a question. We evaluate results of the proposed approach on two new datasets: (i) HW-SQuAD: a synthetic, handwritten document image counterpart of SQuAD1.0 dataset and (ii) BenthamQA: a smaller set of QA pairs defined on documents from the popular Bentham manuscripts collection. We also present a thorough analysis of the proposed recognition-free approach compared to a recognition-based approach which uses text recognized from the images using an OCR.

Quasi-spiral solution to the mixed intracluster medium and the universal entropy profile of galaxy clusters

description: Well-resolved galaxy clusters often show a large-scale quasi-spiral structure in deprojected density $ρ$ and temperature $T$ fields, delineated by a tangential discontinuity known as a cold front, superimposed on a universal radial entropy profile with a linear $K(r)\propto Tρ^{-2/3}\propto r$ adiabat. We show that a spiral structure provides a natural quasi-stationary solution for the mixed intracluster medium (ICM), introducing a modest pressure spiral that confines the locally buoyant or heavy plasma phases. The solution persists in the presence of uniform or differential rotation, and can accommodate both an inflow and an outflow. Hydrodynamic adiabatic simulations with perturbations that deposit angular momentum and mix the plasma thus asymptote to a self-similar spiral structure. We find similar spirals in Eulerian and Lagrangian simulations of 2D and 3D, merger and offset, clusters. The discontinuity surface is given in spherical coordinates $\{r,θ,ϕ\}$ by $ϕ(r,θ)\propto Φ(r)$, where $Φ$ is the gravitational potential, combining a trailing spiral in the equatorial ($θ=π/2$) plane and semicircles perpendicular to the plane, in resemblance of a snail shell. A local convective instability can develop between spiral windings, driving a modified global instability in sublinear $K(r)$ regions; evolved spirals thus imprint the observed $K\propto r$ onto the ICM even after they dissipate. The spiral structure brings hot and cold phases to close proximity, suggesting that the observed fast outflows could sustain the structure even in the presence of radiative cooling.

description: The zero-temperature Ising model is known to reach a fully ordered ground state in sufficiently dense random graphs. In sparse random graphs, the dynamics gets absorbed in disordered local minima at magnetization close to zero. Here, we find that the non-equilibrium transition between the ordered and the disordered regime occurs at an average degree that slowly grows with the graph size. The system shows bistability: The distribution of the absolute magnetization in the reached absorbing state is bimodal, with peaks only at zero and unity. For a fixed system size, the average time to absorption behaves nonmonotonically as a function of average degree. The peak value of the average absorption time grows as a power law of the system size. These findings have relevance for community detection, opinion dynamics, and games on networks.

The removal of heavy metals from municipal wastewaters by lime-magnesium coagulation
Creators: name: MacLean, Byard H.
Publisher: name: University of British Columbia
Year: 2010

description: The evidence of heavy metal build up in the aquatic environment near sewage treatment plant outfalls around Vancouver,coupled with the generally held theory that secondary treatment is not required in this area, leads to the conclusion that a treatment method is required that is primarily aimed at heavy metal removal. In this study, jar tests were performed to evaluate the heavy metal removal efficiency of the lime-magnesium coagulation process. Five heavy metals (Cr³⁺ , Cu²⁺ , Pb²⁺ , Ni²⁺ and Zn²⁺ ) were all tested at initial concentrations of .5, 2.5 and 5.0 mg/1 individually and in combination. The experiments were performed on prechlorinated primary effluent and raw sewage at the natural alkalinity levels (120-130 mg/1 as CaCO₃), and some work was done at elevated alkalinity (190-200 mg/1). The need for filtration in the process was also researched. Results of the study indicated that the heavy metal removal efficiency was enhanced by the presence of Mg²⁺ at a given lime dosage for all of the heavy metals except nickel. A comparison indicated that intermediate lime treatment (220 mg/1) coupled with 33 mg/1 Mg²⁺ might be a more attractive process than just straight high lime treatment (400 mg/1).

description: We consider the quantum nonequilibrium dynamics of systems where fermionic particles coherently hop on a one-dimensional lattice and are subject to dissipative processes analogous to those of classical reaction-diffusion models. Particles can either annihilate in pairs, $A+A \to \emptyset$, coagulate upon contact, $A+A \to A$, and possibly also branch, $A \to A+A$. In classical settings, the interplay between these processes and particle diffusion leads to critical dynamics as well as to absorbing-state phase transitions. Here, we analyze the impact of coherent hopping and of quantum superposition, focusing on the so-called reaction-limited regime. Here, spatial density fluctuations are quickly smoothed out due to fast hopping, which for classical systems is described by a mean-field approach. By exploiting the time-dependent generalized Gibbs ensemble method, we demonstrate that quantum coherence and destructive interference play a crucial role in these systems and are responsible for the emergence of locally protected dark states and collective behavior beyond mean-field. This can manifest both at stationarity and during the relaxation dynamics. Our results highlight fundamental differences between classical nonequilibrium dynamics and their quantum counterpart and show that quantum effects indeed change collective universal behavior.

description: Structural engineering opens a door to manipulating the structures and thus tuning the properties of two-dimensional materials. Here, we report a reversible structural transition in honeycomb CuSe monolayer on Cu(111) through scanning tunneling microscopy (STM) and Auger electron spectroscopy (AES). Direct selenization of Cu(111) gives rise to the formation of honeycomb CuSe monolayers with 1D moiré structures (stripe-CuSe), due to the asymmetric lattice distortions in CuSe induced by the lattice mismatch. Additional deposition of Se combined with post annealing results in the formation of honeycomb CuSe with quasi-ordered arrays of triangular holes (hole-CuSe), namely, the structural transition from stripe-CuSe to hole-CuSe. Further, annealing the hole-CuSe at higher temperature leads to the reverse structural transition, namely from hole-CuSe to stripe-CuSe. AES measurement unravels the Se content change in the reversible structural transition. Therefore, both the Se coverage and annealing temperature play significant roles in the reversible structural transition in CuSe on Cu(111). Our work provides insights in understanding of the structural transitions in 2D materials.

description: In a known gedanken experiment, a delocalized mass is recombined while the gravitational field sourced by it is probed by another (distant) particle; in it, this is used to explore a possible tension between complementarity and causality in case the gravitational field entangles with the superposed locations, a proposed resolution being graviton emission from quadrupole moments. Here, we focus on the delocalized particle (forgetting about the probe and the gedanken experiment) and explore the conditions (in terms of mass, separation, and recombination time) for graviton emission. Through this, we find that the variations of quadrupole moments in the recombination are generically greatly enhanced if the field is entangled compared to if it is sourced instead by the energy momentum expectation value on the delocalized state (moment variation $\sim m \, d^2$ in the latter case, with $m$ mass, $d$ separation). In addition, we obtain the (upper) limit recombination time for graviton emission growing as $m$ in place of the naive expectation $\sqrt{m}$. In this, the Planck mass acts as threshold mass (huge, for delocalized objects): no graviton emission is possible below it, however fast the recombination occurs. If this is compared with the decay times foreseen in the collapse models of Diósi and Penrose (in their basic form), one finds that no (quadrupole) graviton emission from recombination is possible in them. Indeed, right when $m$ becomes large enough to allow for emission, it also becomes too large for the superposition to survive collapse long enough to recombine.

description: The quantum dimer and loop models attract great attentions, partially because the fundamental importance in the phases and phase transitions emerging in these prototypical constrained systems, and partially due to their intimate relevance toward the on-going experiments on Rydberg atom arrays in which the blockade mechanism naturally enforces the local constraint. Here we show, by means of the sweeping cluster quantum Monte Carlo method, the complete ground state phase diagram of the fully packed quantum loop model on the square lattice. We find between the lattice nematic (LN) phase with strong dimer attraction and the staggered phase (SP) with strong dimer repulsion, there emerges a resonating plaquette (RP) phase with off-diagonal translational symmetry breaking. Such a quantum phase is separated from the LN via a first order transition and from the SP by the famous Rokhsar-Kivelson point. Our renormalization group analysis reveals the different flow directions, fully consistent with the order parameter histogram in Monte Carlo simulations. The realization and implication of our phase diagram in Rydberg experiments are proposed.

Convergence of mixed methods in continuum mechanics and finite element analysis

Publisher: name: University of British Columbia

description: The energy convergence of mixed methods of approximate analysis for problems involving linear self-adjoint operators is investigated. A new energy product and the associated energy norm are defined for such indefinite systems and then used in establishing the strain energy convergence and estimation of error for problems in continuum mechanics. In the process, the completeness requirements are laid out for approximate solutions. Also established is the mean convergence of the basic variable e.g. displacements and stresses. After accomplishing a new mathematical framework for the mixed methods in continuum, the theory is then extended to the finite element method. The completeness requirements, convergence criteria and the effect of continuity requirements on convergence are established. The flexibility offered by the mixed methods in incorporating the boundary con ditions is also demonstrated. For stress singular problems, the strain energy convergence is established and an energy release method for determining the crack intensity factor K. is presented. A detailed eigenvalue-eigenvector analysis of the mixed finite element matrix is carried out for various combinations of interpolations for the plane stress linear elasticity and the linear part of the Navier-Stokes equations. Also discussed is its relation to the completeness requirements. Finally, numerical results are obtained from applying the mixed finite element method to several examples. These include beam bending, a plane stress square plate with parabolically varying end loads, a plane stress cantilever and plane strain stress concentration around a circular hole. A plane stress example of a square plate with symmetric edge cracks is also solved to study the strain energy convergence. Lastly, two rectangular plates, one with symmetric edge cracks and the other with a central crack are considered to determine the crack intensity factor K. In most of the examples, the strain energy convergence rates are predicted and compared with the numerical results, and excellent agreement is observed.

description: In this study, we investigate the Pauli oscillator in a noncommutative space. In other words, we derive wave function and energy spectrum of a spin half non-relativistic charged particle that is moving under a constant magnetic field with an oscillator potential in noncommutative space. We obtain critical values of the deformation parameter and the magnetic field, which counteract the normal and anomalous Zeeman effects. Moreover, we find that the deformation parameter has to be smaller than $2.57\times 10^{-26}m^2$. Then, we derive the Helmholtz free energy, internal energy, specific heat, and entropy functions of the Pauli oscillator in the noncommutative space. With graphical methods, at first, we compare these functions with the ordinary ones, and then, we demonstrate the effects of magnetic field on these thermodynamic functions in the commutative and noncommutative space, respectively
title: Confidence building measures in South Asia

Publisher: name: University of Kent

description: This dissertation evolves a theoretical framework of the concept of Confidence Building Measures and applies it to the case-study of India Pakistan relations in the South Asia region. Part I examines the Confidence Building Measures in a global regional perspective. It outlines a theoretical framework of Confidence Building Measures by putting forward an appropriate definition of this concept and conceptualising the confidence building process in a model. It explores the empirical universe of Confidence Building Measures on a global scale in a conflict and crisis framework, in terms of its functional dimensions and at different levels of analysis. This provides a conceptual and empirical backdrop for an examination of Confidence Building Measures in the South Asian region. Part II studies the trends of conflict and cooperation in India-Pakistan relations in the first two decades after independence in 1947 and sets the stage for a more formal reconciliation process between the two countries in the post-Simla Agreement (1972) period. It also examines the operational variables given in the Indian and Pakistani political milieu that shape their bilateral confidence building process. Part III presents a detailed analysis of the India-Pakistan confidence building process in its political, military, economic and socio-cultural dimensions in the last two decades. The core issues of India-Pakistan conflict, the Kashmir conflict and Pakistan's alleged involvement in supporting terrorism in the Indian states of Punjab and Jammu and Kashmir have also been discussed. Part IV summarizes the major findings and conclusions of the study and puts forward some suggestions which may facilitate the confidence building process between India and Pakistan. The dissertation has relied on information gathered from the field work research carried out in India and Pakistan in Winter 1991-1992.

description: Excerpts from the report Introduction: This survey was addressed to the problem of the competitive position of cotton and other fibers in specific end-use markets. Market outlets for household and apparel textiles are largely determined by the actions of ultimate consumers. Information of various kinds is available at the manufacturing, converting, fabricating, wholesaling, and retailing levels, but there are few adequate data on consumer preferences. Consequently, information relating to factors affecting consumer preferences for textile products is needed to supplement that already assembled or being assembled on other phases of the problem. The Cotton Subcommittee of the House Committee on Agriculture has been investigating problems affecting cotton and suggesting solutions to them. One part of this investigation resulted in the establishment of nine active projects dealing with agricultural economic problems of the Cotton Belt. One of these nine was a project to examine the competitive position of cotton by major end-use products. Members of this particular project committee urged the Bureau of Agricultural Economics to proceed with a survey to learn consumer preferences with respect to selected textile products. Such a survey was undertaken. A sample of 1,782 women was selected and interviewed. These women represented all women in the United States between the ages of 18 and 65, and homemakers of any age. The results are reported here. A copy of the interview schedule is included in the appendix.

description: The central engine of gamma-ray bursts (GRBs) remains an open and forefront topic in the era of multimessenger astrophysics. The X-ray plateaus appear in some GRB afterglows, which are widely considered to originate from the spindown of magnetars. According to the stable magnetar scenario of GRBs, an X-ray plateau and a decay phase as $\sim t^{-2}$ should appear in X-ray afterglows. Meanwhile, the ``normal'' X-ray afterglow is produced by the external shock from GRB fireball. We analyze the Neil Gehrels \emph{Swift} GRB data, then find three gold samples, which have an X-ray plateau and a decay phase as $\sim t^{-2}$ superimposed on the jet-driven normal component. Based on these features of the lightcurves, we argue that the magnetars should be the central engines of these three GRBs. Future joint multimessenger observations might further test this possibility, then which can be beneficial to constrain GRB physics.
