Marrithiyel : a language of the Daly River region of Australia's Northern Territory
Creators: name: Green, Ian
Publisher: name: The Australian National University
Year: 1989

description: This is a study of Marrithiyel, a language of the Daly River region of the Northern Territory. Chapter One presents a brief introduction to the language and its speakers, and outlines my fieldwork methodology. Chapter Two then reviews the phonology, word classes, and the nominal case marking system. These matters are not treated exhaustively, but are rather presented as preliminaries to a study of the verb, the topic to which the major part of this thesis is devoted. Chapter Three is primarily concerned with the morphology of pronominal verbal affixes. This chapter introduces the basic verbal constituents: the auxiliary, the complex verb stem, the boundpronominal number markers, and the tense/mood suffixes. The bound pronominals of the auxiliary are identified, and their various functions (including person, number, core role, tense/mood, and transitivity marking) outlined. Three further sets of pronominals, able to appear at a subsequent position in the verb, encoding more peripheral roles, are also examined. Chapter Four deals with the tense/aspect/mood distinctions carried by the verb, outlining the seven major tense/mood categories, and analysing the aspectual role of the intransitive auxiliaries. The incorporation into the verb of a number of temporal modifiers, tense/mood suffixing of certain non-verbal constituents, and iterative verb-root reduplication are also considered. Chapter Five investigates the incorporation of noun roots into the verb, a process primarily involving a restricted set of body part terms. Two types of incorporation, "lexical" and "syntactic", are distinguished, and the domain and effect of each type of incorporation looked at in detail. The semantic range of body part terms, which may be incorporated in either literal or classificatory senses, is surveyed, and a number of verb stem derivations involving body part terms are presented. Chapter Six examines the semantic contribution made by the auxiliary to overall verbal meaning. Three groups of auxiliaries, the "major transitive", the "major intransitive", and the "minors", are identified and discussed. The major transitives are analysed as essentially instrumental in semantic character, while the major intransitives are seen as having more of a postural-aspectual function. Detailed exemplification is given throughout, and there is an illustrative text provided at the end of this study.

description: We present the results from new deep {\it Chandra} ($\sim410$~ks) and {\it Suzaku} ($\sim180$ ks) observations of the merging galaxy cluster ZwCl\,0008.8+5215 ($z=0.104$). Previous radio observations revealed the presence of a double radio relic located diametrically west and east of the cluster center. Using our new {\it Chandra} data, we find evidence for the presence of a shock at the location of the western relic, RW, with a Mach number $\mathcal{M}_{S_X}=1.48^{+0.50}_{-0.32}$ from the density jump. We also measure $\mathcal{M}_{T_X}=2.35^{+0.74}_{-0.55}$ and $\mathcal{M}_{T_X}=2.02^{+0.74}_{-0.47}$ from the temperature jump, with {\it Chandra} and {\it Suzaku} respectively. These values are consistent with the Mach number estimate from a previous study of the radio spectral index, under the assumption of diffusive shock acceleration ($\mathcal{M}_{\rm RW}=2.4^{+0.4}_{-0.2}$). Interestingly, the western radio relic does not entirely trace the X-ray shock. A possible explanation is that the relic traces fossil plasma from nearby radio galaxies which is re-accelerated at the shock. For the eastern relic we do not detect an X-ray surface brightness discontinuity, despite the fact that radio observations suggest a shock with $\mathcal{M}_{\rm RE}=2.2^{+0.2}_{-0.1}$. The low surface brightness and reduced integration time for this region might have prevented the detection. {\it Chandra} surface brightness profile suggests $\mathcal{M}\lesssim1.5$, while {\it Suzaku} temperature measurements found $\mathcal{M}_{T_X}=1.54^{+0.65}_{-0.47}$. Finally, we also detect a merger induced cold front on the western side of the cluster, behind the shock that traces the western relic.

description: Nowadays, the electrocardiogram (ECG) is still the most widely used signal for the diagnosis of cardiac pathologies. However, this recording is often disturbed by the powerline interference (PLI), its removal being mandatory to avoid misdiagnosis. Although a broad variety of methods have been proposed for that purpose, often they substantially alter the original signal morphology or are computationally expensive. Hence, the present work introduces a simple and efficient algorithm to suppress the PLI from the ECG. Briefly, the input signal is decomposed into four Wavelet levels and the resulting coefficients are thresholded to remove the PLI estimated from the TQ intervals. The denoised ECG signal is then reconstructed by computing the inverse Wavelet transform. The method has been validated making use of fifty 10-min length clean ECG segments obtained from the MIT BIH Normal Sinus Rhythm database, which were contaminated with a sinusoidal signal of 50 Hz and variable harmonic content. Comparing the original and denoised ECG signals through a signed correlation index, improvements between 10 - 72% have been observed with respect to common adaptive notch filtering, implemented for comparison. These results suggest that the proposed method is featured by an enhanced trade-off between noise reduction and signal morphology preservation.

description: The emergence of distributed generation and the electrification of demand have opened the possibility for prosumers to participate in electricity markets, receiving economic benefits on their bills and contributing to the reduction of carbon emissions, aligning with United Nations Sustainable Development Goal 7. Consumers and prosumers can participate through implicit and explicit demand flexibility and (collective) self-consumption. This study analyses the potential markets in which prosumers can participate and indicates whether these are currently open. The markets studied include day-ahead, intraday, ancillary services, adequacy services, constraint management, and local flexibility markets. Additionally, collective self-consumption is analysed as a service through which prosumers can participate in the electricity market. Previous studies are usually focused on a single market or in a single country, making impossible a complete comparison. This analysis has been done in Spain, Italy, Croatia, and the United Kingdom as representative countries to obtain a methodology to assess countries' openness to prosumer participation in electricity markets, comparing regulatory frameworks and assigning scores based on their prosumer inclusion across various markets. This work updates current literature reviews with the changes and a new description of local market designs in Spain. This methodology can be used to compare other countries' grade of openness. The results of this study show that the analysed countries can be categorised into three groups: almost open, partially open, and closed markets. Analysing the differences, recommendations on the following steps to foster user participation are suggested for each group.

Spectra of PP-Wave Limits of M-/Superstring Theory on AdS_p x S^q Spaces

description: In this paper we show how one can obtain very simply the spectra of the PP-wave limits of M-theory over AdS_7(4) x S^4(7) spaces and IIB superstring theory over AdS_5 x S^5 from the oscillator construction of the Kaluza-Klein spectra of these theories over the corresponding spaces. The PP-wave symmetry superalgebras are obtained by taking the number P of ``colors'' of oscillators to be large (infinite). In this large P limit, the symmetry superalgebra osp(8*|4) of AdS_7 x S^4 and the symmetry superalgebra osp(8|4,R) of AdS_4 x S^7 lead to isomorphic PP-wave algebras, which is the semi-direct sum of su(4|2) with H^(18,16), while the symmetry superalgebra su(2,2|4) of AdS_5 x S^5 leads to the semi-direct sum of [psu(2|2) + psu(2|2) + u(1)] with H^(16,16) as its PP-wave algebra [H^(m,n) denoting a super-Heisenberg algebra with m bosonic and n fermionic generators]. The zero mode spectra of M-theory or IIB superstring theory in the PP-wave limit corresponds simply to the unitary positive energy representations of these algebras whose lowest weight vector is the Fock vacuum of all the oscillators. General positive energy supermultiplets including those corresponding to higher modes can similarly be constructed by the oscillator method.

The decline of the Muslim league and the ascendancy of the bureaucracy in East Pakistan 1947-54
Creators: name: Kamal, A H Ahmed
Publisher: name: The Australian National University
Year: 1989

description: This thesis looks at the career of the Muslim League in East Pakistan from 14 August 1947, the day it assumed political power, to the election of 8 March 1954, when it was massively defeated by a newly-formed United Front. Exploring the decline of the popularity of the League is one objective of the thesis. In the process, it also seeks to explain the nature of 'politics' in East Pakistan. In particular, the emergence of a state bureaucracy with paternalistic and undemocratic tendencies, is documented and analysed. This is shown to be a lasting legacy of the British Raj and of Muslim League politics in East Pakistan (now Bangladesh). The process through which the bureaucracy grew stronger by the day also entailed the growing alienation of the people from both the government and the ruling party, the League. Explaining this alienation is another concern of the thesis. These themes are highlighted in a series of chapters devoted to certain specific and important issues that the League government had to deal with during its stay in power: politics of food procurement and distribution, abolition of zamindari and other exploitative feudal relationships, the problem of controlling water resources in a flood-prone country, and finally, the relationship between the people and the regulative institutions of the state such as the police and its auxiliaries. An examination of these issues usefully complements what students of East Pakistan politics have (rather selectively) emphasised so far: the Language movement of the 1950s, the crisis of federalism and problems of jute marketing. An argument is eventually built up on the nature of the state and 'nationhood' in East Pakistan. The preponderance of the bureaucracy in the colonial style of government, the peculiar history of Muslim nationalism in the subcontinent, the lack, in the League's history, of a tradition of anti-imperialist struggle and ideology, and finally, the weak nature of the ML's organisation and mass base, are all seen as factors that contributed significantly to the growing 'undemocracy' of which both East Pakistan, and later Bangladesh, were unfortunate victims.

description: Entangling quantum systems with different characteristics through the exchange of photons is a prerequisite for building future quantum networks. Proving the presence of entanglement between quantum memories for light working at different wavelengths furthers this goal. Here, we report on a series of experiments with a thulium-doped crystal, serving as a quantum memory for 794 nm photons, an erbium-doped fibre, serving as a quantum memory for telecommunication-wavelength photons at 1535 nm, and a source of photon pairs created via spontaneous parametric down-conversion. Characterizing the photons after re-emission from the two memories, we find non-classical correlations with a cross-correlation coefficient of $g^{(2)}_{12} = 53\pm8$; entanglement preserving storage with input-output fidelity of $\mathcal{F}_{IO}\approx93\pm2\%$; and non-locality featuring a violation of the Clauser-Horne-Shimony-Holt Bell-inequality with $S= 2.6\pm0.2$. Our proof-of-principle experiment shows that entanglement persists while propagating through different solid-state quantum memories operating at different wavelengths.

Commun. 54, 189 (1985) ] and the quantum-classical correspondence. Using this method, we find analytically the dynamics of nonclassical states generation in the higher-order anharmonic dissipative oscillators for an arbitrary temperature of a reservoir. We show that the quantum correction to the classical motion increases with time quadratically up to some maximal value, which is dependent on the degree of nonlinearity and a damping constant, and then it decreases. Similarities and differences with the corresponding behavior of the quantum corrections to the classical motion in the Hamiltonian chaotic systems are discussed. We also compare our results obtained for some limiting cases with the results obtained by using other semiclassical tools and discuss the conditions for validity of our approach.

description: Analysis of intra-atrial electrograms (EGMs) nowadays constitutes the most common way to gain new insights about the mechanisms triggering and maintaining atrial fibrillation (AF). However, these recordings are highly contaminated by powerline interference (PLI) due to the large amount of electrical devices operating simultaneously in the electrophysiology laboratory. To remove this perturbation, conventional notch filtering has been widely used. However, this method adds artificial fractionation to the EGMs, thus concealing their accurate interpretation. Hence, the development of novel algorithms for PLI suppression in EGMs is still an unresolved challenge. Within this context, the present work introduces the joint application of common notch filtering and Wavelet denoising for enhanced PLI removal in AF EGMs. The algorithm was validated on a set of 100 unipolar EGM signals, which were synthesized with different noise levels. Original and denoised EGMs were compared in terms of a signed correlation index (SCI), computed both in time and frequency domains. Compared with the single use of notch filtering, improvements between 4 and 15% were reached with Wavelet denoising in both domains. As a consequence, the proposed algorithm was able to efficiently reduce high levels of PLI and simultaneously preserve the original morphology of AF EGMs.

description: We analyse some physical consequences when supersymmetry is broken by a set of D-branes and/or orientifold planes in Type II string theories. Generically, there are global dilaton tadpoles at the disk level when the transverse space is compact. By taking the toy model of a set of electric charges in a compact space, we discuss two different effects appearing when global tadpoles are not cancelled. On the compact directions a constant term appears that allows to solve the equations of motion. On the non-compact directions Poincaré invariance is broken. We analyse some examples where the Poincaré invariance is broken along the time direction (cosmological models).After that, we discuss how to obtain a finite interaction between D-branes and orientifold planes in the compact space at the supergravity level.

'Be candid where we can' : the rational dissent of Joseph Priestley
Creators: name: Saunders, Alan John
Publisher: name: The Australian National University
Year: 1989

description: This essay locates the origins of the religious and political radicalism of Joseph Priestley in his early abandonment of Calvinism: having deprived himself of a powerful, subjective system of explanation, he sought a view of the world that could be justified by entirely objective criteria. He was assisted in this project by the psychological theory of associationism - which purports to provide an empirical explanation of mental activity - and by the concept of candour: which in the eighteenth century embodied not only frankness but also a certain generosity of spirit and a willingness to engage in unacrimonious debate. In the central chapters of this essay, four aspects of his work are examined: his activity as an historian (and to some extent as a scientist, an historian of nature), his theology and preaching, his philosophical writings and his political theory, in each of these areas, his work is marked by concern for objectivity and devotion to associationism. He saw history as a providential mechanism in which mental associations played an essential role and he looked to history to provide empirical, objective justification for Christian belief. He found, however, that there were some Christian dogmas - notably that of Christ's divinity - which could not be so justified, and he abandoned them. He thus came to oppose (even more strongly than orthodox dissenters) the religious foundations of the British state; he advocated instead a candid free market in ideas (by means of which God’s providence could operate unhindered). The final chapter describes how this project came to grief, having written an historical account of the growth of those Christian doctrines to which he was opposed, Priestley hoped that he could engage in candid conversation with his critics. But he underestimated the alarm which his opinions provoked, especially in the years after the fall of the Bastille: the debate grew heated, he was publically vilified and, at last, forced into exile.
Jordan frame beyond scalar-tensor theories

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: We study the Jordan frame formulation of generalizations of scalar-tensor theories conceived by replacing the scalar with other fields such as vectors. The generic theory in this family contains higher order time derivative terms in the Jordan frame action which is indicative of ill-posedness. However, we show that equations of motion can always be reduced to a second-order-in-time form as long as the original Einstein frame formulation is well posed. The inverse transformation from the Jordan frame back to the Einstein frame is not possible for all field values in all theories, but we obtain a fully invertible transformation for vector-tensor theories by a redefinition of the vector field. Our main motivation is a better understanding of spontaneous scalarization and its generalizations, however our conclusions are applicable to a wide class of theories. Jordan frame has been traditionally used for certain calculations in scalar-tensor theories of gravitation, and our results will help researchers generalize these results, enabling comparison to observational data.

This model has two degrees of freedom per base-pair: one radial variable related to the opening of the hydrogen bonds and an angular one related to the twisting of each base-pair responsible for the helicoidal structure of the molecule. The small amplitude dynamics of the model is studied analytically : we derive small amplitude envelope solutions made of a breather in the radial variables combined with a kink in the angular variables, showing the role of the topological constraints associated to the helicoidal geometry. We check the stability of the solutions by numerical integration of the motion equations.

description: The manipulation of garments poses research challenges due to their deformable nature and the extensive variability in shapes and sizes. Despite numerous attempts by researchers to address these via approaches involving robot perception and control, there has been a relatively limited interest in resolving it through the co-development of robot hardware. Consequently, the majority of studies employ off-the-shelf grippers in conjunction with dual robot arms to enable bimanual manipulation and high dexterity. However, this dual-arm system increases the overall cost of the robotic system as well as its control complexity in order to tackle robot collisions and other robot coordination issues. As an alternative approach, we propose to enable bimanual cloth manipulation using a single robot arm via novel end effector design -- sharing dexterity skills between manipulator and gripper rather than relying entirely on robot arm coordination. To this end, we introduce a new gripper, called G.O.G., based on a gripper-on-gripper structure where the first gripper independently regulates the span, up to 500mm, between its fingers which are in turn also grippers. These finger grippers consist of a variable friction module that enables two grasping modes: firm and sliding grasps. Household item and cloth object benchmarks are employed to evaluate the performance of the proposed design, encompassing both experiments on the gripper design itself and on cloth manipulation. Experimental results demonstrate the potential of the introduced ideas to undertake a range of bimanual cloth manipulation tasks with a single robot arm.

description: It has been recently shown that the eigenvalues of the Dirac operator can be considered as dynamical variables of Euclidean gravity. The purpose of this paper is to explore the possiblity that the eigenvalues of the Dirac operator might play the same role in the case of supergravity. It is shown that for this purpose some primary constraints on covariant phase space as well as secondary constraints on the eigenspinors must be imposed. The validity of primary constraints under covariant transport is further analyzed. It is show that in the this case restrictions on the tanget bundle and on the spinor bundle of spacetime arise. The form of these restrictions is determined under some simplifying assumptions. It is also shown that manifolds with flat curvature of tangent bundle and spinor bundle and spinor bundle satisfy these restrictons and thus they support the Dirac eigenvalues as global observables.

Ignorance (Theory of knowledge) in literature

description: Theater of Enigma in Shakespeare’s England demonstrates the cognitive, affective, and social import of enigmatic theatrical moments. While the presence of other playgoers obviously shapes the experience of attending a play, I argue that deliberately induced moments of audience ignorance are occasions for audience members to be especially aware of their relations to others who may or may not share their bafflement. I explore the character of states of knowing and not-knowing among audience members and the relations that obtain among playgoers who inhabit these states. Further, I trace the range of performance techniques whereby playgoers are positioned in a cognitive no-man's land, lying somewhere between full understanding and utter ignorance—techniques that I collectively term “enigmatic theater.”
      I argue that moments of enigmatic theater were a dynamic agent in the formation of collectives in early modern playhouses. I use here the term “collective” to denote the temporary, occasional, and fleeting quality of these groupings, which occur during performance but are dissipated afterwards. Sometimes, this collective resembles what Victor Turner terms communitas, in which the normal societal divisions are suspended and the playgoers become a unified collectivity. At other times, however, plays solicit the formation of multiple collectives defined by their differing degrees of knowledge about a seeming enigma. In either case, I show that a core achievement of early modern theater of enigma was to link issues of knowledge with issues of belonging—even when that pleasurable sense of belonging is as transient as the occasion of performance.

Art and the war

description: This dissertation is about the ways in which modern war, modern medicine, and modern theatre have reciprocally shaped attitudes towards bodies. I argue that the rise of theatrical realism, taking models and metaphors from newly technologized war and medicine, gives viewers the power to see into others, and envisions this force as a mark of superior humanity. I show how this gaze is engaged in performance events that dramatize war-as-medicine: from WWI theatre-for-the-troops depicting enemy soldiers as microbes, to the 2003 televised medical exam of Saddam Hussein. I argue that the tools and rhetoric of realism are instrumental in imagining distanced killing as a medicinal and sanitizing act, thus naturalizing violence-as-care. Over the same period, I study the work of military veteran theatre makers who have practiced theatre as an alternative medicine: healing not by distance and separation, but through a visceral connection between performers and spectators. Starting with Antonin Artaud’s theatrical “surgery,” I progress through chapters on Edward Bond, David Rabe, Frances Ya-Chu Cowhig, the Riot Group, and Sylvia Khoury. Taking theoretical frameworks from medical humanities and disability studies, and integrating methods from cognitive science and phenomenology, I explore how their theatre opens up corporeal space for resonance, receptivity, and transformation. I conclude by looking at current applied theatre projects bringing together groups of military service members and civilians, and healthcare providers and receivers. I argue that theatre is uniquely able to heal the selective numbing involved in military and medical training, by resensitizing bodies and relearning ways of caring for oneself and others.
Theatrical Ticketing: A Contemporary Drama

Theater--Economic aspects

description: This analysis will first look at theatrical ticketing over recent history, establishing how the traditional vendors of tickets for live commercial theatrical productions in New York are set up and structured. Next, we will explore various elements of the theatrical ticketing industry under the framework of Porter’s Five Forces to begin our investigation into the viability for change and development and establish the attractiveness of the industry for new entrants to the space. Finally, specific examples of more recent technologies will be examined, considering their strengths and weaknesses to support the needs of theatre consumers and theatre creators as well as the potential obstacles for their growth and impact on the industry as a whole.

description: This paper will examine the incidents in detail and attempt to propose solutions to address the current vulnerabilities of Broadway theatres. Chapter 1 will provide a brief overview of the current and emerging trends in domestic and international terrorism, discussing their relevance to the theme of this thesis. Chapter 2 will provide an in-depth look at the events at the Dubrovka theatre in October 2002, when a coordinated attack was executed by a host of Chechen extremists, taking hostage over 900 theatregoers and employees. Chapter 3 will discuss the November 2015 attack on Stade de France and the Bataclan Concert Hall carried out by ISIS forces. The fourth chapter will look into the possible effects of new security measures being implemented and what considerations may be halting their application on Broadway and in other regions around the world. The chapter will then go on to offer a range of measures either already in use in some theatres in the world, or about to be implemented, which would fill some of the holes in theatre security.
Theatre on Trial: Staging Postwar Justice in the United States and Germany

description: This dissertation studies the interchange between political theatre and postwar political trials. I argue that to an extraordinary extent, theatre history in this period is inextricable from trial history. Through close archival study of mid-century theatre productions including Bertolt Brecht's 1954 production of "The Caucasian Chalk Circle" and the fifteen simultaneous premiere productions of Peter Weiss's "The Investigation" in 1965, I show how directors and playwrights looked to legal trials in order to develop and articulate theories of epic and documentary theatre, and how this new theatre in turn sought to effect justice in ways that trials alone could not.
Annual Report of the Bank of Japan (1906)

description: Annual Report of the Bank of Japan for the year 1906. The Report contains the Bank's official viewpoint on the economic conditions of the country, as well as the 'financial operations in the year under review'. It details elements as the bank rate, inflation etc. A most important aspect is its treatment of the outflow and inflow of specie, as the latter was tightly bound up with the country's management of the recently adopted goldstandard (1897).Every report includes an appendix detailing total operations, bank notes issued, the discount of commercial bills, the rate of discount, loans ans their rates of interest, ..., transactions in precious metals.

description: Galaxy clusters grow by gas accretion, mostly from mergers of substructures, which release powerful shock waves into cosmic plasmas and convert a fraction of kinetic energy into thermal energy, amplification of magnetic fields and into the acceleration of energetic particles. The modeling of the radio signature of cosmic shocks, combined with the lack of detected gamma-rays from cosmic ray (CR) protons, poses challenges to our understanding of how cosmic rays get accelerated and stored in the intracluster medium. Here we review the injection of CRs by cosmic shocks of different strengths, combining the detailed "microscopic" view of collisionless processes governing the creation of non-thermal distributions of electrons and protons in cluster shocks (based on analytic theory and particle-in-cell simulations), with the "macroscopic" view of the large-scale distribution of cosmic rays, suggested by modern cosmological simulations. We discuss time dependent non-linear kinetic models of particle acceleration by multiple internal shocks with large scale compressible motions of plasma. The models produce soft CR spectra containing a noticeable energy density in the super-thermal protons of energies below a few GeV which are difficult to constrain by Fermi observations. We consider the effect of plasma composition on CR injection and super-thermal particle population in the hot intracluster matter which can be constrained by fine high resolution X-ray spectroscopy of Fe ions.

Theoretical Study of Electron Transport and Trapping in Solvated Titanium Dioxide Nanoparticles
Creators: Zhang, Jing
Publisher: name: Columbia University
Year: 2013
Subjects: Chemistry

description: This thesis consists of two parts of work: the advances on the efficient and robust implementation of our quantum chemistry program Jaguar for large DFT calculations, and theoretical modeling of electron transport and trapping in solvated TiO_2 nanoparticles. In first half, We implemented an OpenMP/MPI hybrid parallelization implementation of the pseudospectral algorithm, developed a fragment based initial guess methodology which is suitable for addressing systems with significant delocalization, and improved numerical robustness with regard to the converged wavefunction. The parallel scalability is enhanced greatly from ∼16 to ∼128, which enables a hybrid-DFT calculation for a system with up to 5000 basis functions. Those advances enable Jaguar to be used in a wide range of materials science problems that previously were not accessible to our approach.In second half, by employing a large cluster, a hybrid DFT model (B3LYP), and a realistic treatment of solvent, we proposed an atomically detailed model for the electronic states involved in transport and trapping, and obtain good agreement with experiment for properties such as the energetics of the trapping states and the barriers to hopping conduction by electrons. The results suggest the existence of energetically shallow electron trapping states at (sub) surface region induced by the presence of small cations and the continuum solvent effect. The barrier heights imply that concerted ambipolar diffusion of the Li+/e − can occur under thermal activation, but it is energetically disfavored for proton/e− pair. Those results advance our understanding of the effect of the cation and solvent on the density of states (DOS) of electron traps, and establish the plausibility that ambipolar model plays a role in electron transport through TiO_2 film in DSSC.
Rural electrification in Indonesia : policy implementation in theory and practice
Creators: name: Husin, Imron
Publisher: name: The Australian National University
Year: 1989

description: The study of policy implementation in developed countries is relatively new, virtually starting with the major Wildavsky and Pressman study of the Oakland project (1971)- and even less has been done so far in relation to Third World countries. This thesis is an attempt to throw light on the degree to which implementation of a government policy in Indonesia conforms with the various objectives of the government in formulating such a policy and what problems emerge in the implementation process. In Chapter 2 and 3, the formulation and the implementation of the rural electrification program in Indonesia, and East Java in particular, is investigated. In order to understand the process of implementation of the program at the lower level and to examine what happened to the program when it reached down to the target group, this study has looked at the two different rural areas (one agricultural and one industrial in character) of Pare and Pandaan, which have both had long experience of electricity service (Chapter 4). This study has found that the length of supply of electricity seems to bear no relationship at all to the growth of industry. There is very little evidence to support the proposition that the program has improved income, created employment opportunities or stimulated much industrialization in rural areas. Instead, in the absence of many household activities in the area concerned, electrification has stimulated higher consumerism among electricity consumers. In Pare, the existence of a variety of household activities prior to electrification has helped to increase slightly the average power consumption for productive activities, while in Pandaan the household consumers mostly used the power for consumption purposes. Moreover, the failure to take into account the existing unequal distribution of economic and social power in rural communities has added to greater inequalities (Chapter 4, 5 and 6). The main conclusion to this study is that planning should not be regarded as a process that is entirely separate from its implementation: on the contrary, the principles of good public policy call for constant monitoring, feedback and adjustment of both objectives, priorities and the mechanisms for implementation during the course of the program, not just at its conclusion. Moreover, the degree to which a program has achieved its objectives ought to be assessed on the basis of the quality as well as the quantity of the outcomes, not solely on the basis of certain numerical targets achieved. A preoccupation with achieving targets frequently gives rise to deviations from the various main objectives initially intended by the original policy makers.

description: A Procedure is outlined that may be used as a starting point for a perturbative treatment of theories with permanent confinement. By using a counter term in the Lagrangian that renormalizes the infrared divergence in the Coulomb potential, it is achieved that the perturbation expansion at a finite value of the strong coupling constant may yield reasonably accurate properties of hadrons, and an expression for the string constant as a function of the QCD Lambda parameter.
