description: In this research we provide a set of practical approaches to value crude oil futures, especially long dated ones given crude oil spot prices. Throughout the research we change the reference point for our data sets from calendar dates to time to expiry and all our models are analyzed based on time to expiry. We use a set of Levy processes to value crude oil options by calibrating parameters using Fast Fourier Transform algorithm and solving an objective function using Particle-Swap Optimization. In order to help market participants to use available crude oil storage and refinery data in pricing futures contracts and the spreads between them, we provide a framework that helps crude oil market participants to get fair value of futures and run scenario analysis if a physical factor such as level of inventories at Cushing\Oklahoma or in the US changes. We also investigated variance risk premia in crude oil prices using information obtained from crude oil option prices. Our results indicate that “usually” there is a negative risk premium in crude oil prices but that does not necessarily provide trading opportunity for market participants because excess return of shorting the variance swap show huge losses when crude oil market is in turmoil.

subject: clinical social work

description: Existing literature exploring the integration of Hip Hop in therapeutic contexts predominately focuses on utilizing the music in a receptive fashion, while a limited amount of literature has explored active techniques (i.e., lyric composition). Utilizing a qualitative phenomenological method, this study explored the experience of composing Hip Hop lyrics of young people who have been labelled ‘at risk’ (N=5). From the participant interviews emerged seven categories related to the experience of composing Hip Hop: (a) Hip Hop as a constant in one’s life, (b) Descriptions of the composing process, (c) Hip Hop song composition is therapeutic, (d) Hip Hop supports expression, (e) Remixing the story: Constructing and living the story we tell of ourselves, (f) Acts of resistance: ‘Each one, teach one’, and (g) Delivery of content: Messages within messages. The findings are discussed in relation to existing literature and implications are offered for the clinical social work context.

description: Zebra pattern structure (ZP) is the most intriguing fine structure on the dynamic spectrograph of solar microwave burst. On 15 February 2011, there erupts an X2.2 flare event on the solar disk, it is the first X-class flare since the solar Schwabe cycle 24. It is interesting that there are several microwave ZPs observed by the Chinese Solar Broadband Radiospectrometer (SBRS/Huairou) at frequency of 6.40 ~ 7.00 GHz (ZP1), 2.60 ~ 2.75 GHz (ZP2), and the Yunnan Solar Broadband Radio Spectrometer (SBRS/Yunnan) at frequency of 1.04 ~ 1.13 GHz (ZP3). The most important phenomena is the unusual high-frequency ZP structure (ZP1, up to 7.00 GHz) occurred in the early rising phase of the flare, and there are two ZP structure (ZP2, ZP3) with relative low frequencies occurred in the decay phase of the flare. By scrutinizing the current prevalent theoretical models of ZP structure generations, and comparing their estimated magnetic field strengths in the corresponding source regions, we suggest that the double plasma resonance model should be the most possible one for explaining the formation of microwave ZPs, which may derive the magnetic field strengths as about 230 - 345 G, 126 - 147 G, and 23 - 26 G in the source regions of ZP1, ZP2, and ZP3, respectively.

description: Most of the modern conventional inversion packages that are available to universities and industry use a 1D forward model with 1D dataset being inverted independently and then combined together to form a pseudo 2D or 3D image. I refer to this approach as 1D Laterally Unconstrained Inversion (1D-LUI). The simplicity of a 1D forward model enables geophysicists to obtain results and model scenarios in a short time but sometimes at the cost of a low quality inverted image. In this thesis, I present a 1D laterally constrained inversion (1D-LCI) where the 1D datasets are inverted simultaneously. This algorithm produces layers in a section with laterally smoothed transition zones and sharp layer boundaries, while maintaining computational efficiency. We demonstrate the effectiveness of this approach on a series of poststack synthetic 2D models as well as a 2D poststack field dataset. The results of 1D-LCI results show clear improvement over the conventional method. This algorithm should be of interest to a wide variety of applied geophysicists looking to improve impedance-imaging results with a small increase in computational cost. While the results of the 1D-LCI are promising, it fails to image steeply dipping structures clearly and those events were smeared out laterally. In this work, I develop Structurally Constrained Inversion (SCI). SCI involves simultaneous inversion of all seismic traces of poststack seismic data using a regularization operator that forces the solution to honor local structure. The proposed method involves a multi trace-based impedance inversion and a rotation of an orthogonal system of derivatives operators. We illustrate the effectiveness of 1D-SCI algorithm on a synthetic 2D model as well as a field seismic dataset. The inversion results were able to image clearly the steeply dipping event, recover complex structures and produce low noise images in the estimated model parameters. The results look more geologically realistic when compared to trace-by-trace and Laterally Constrained Inversion respectively. Lastly, it was necessary to extend the LCI and SCT algorithms to the prestack seismic data as the post-stack seismic inversion results in many cases is not enough to detect fluid type or differentiate lithological units that have close or similar P- impedance signatures. The multi-trace simultaneous pre-stack inversion of LCI and SCI has been successfully applied to 2D seismic data of Coal bed methane exploration project as well as to a complex 2D dataset of a gas carbonate reservoir in the foothills region of Alberta.

description: Dense mixture of granules and liquid often shows a sever shear thickening and is called a dilatant fluid. We construct a fluid dynamics model for the dilatant fluid by introducing a phenomenological state variable for a local state of dispersed particles. With simple assumptions for an equation of the state variable, we demonstrate that the model can describe basic features of the dilatant fluid such as the stress-shear rate curve that represents discontinuous severe shear thickening, hysteresis upon changing shear rate, instantaneous hardening upon external impact. Analysis of the model reveals that the shear thickening fluid shows an instability in a shear flow for some regime and exhibits {\it the shear thickening oscillation}, i.e. the oscillatory shear flow alternating between the thickened and the relaxed states. Results of numerical simulations are presented for one and two-dimensional systems.

description: Flower-like nanostructures formed by ZnO nanorods were synthesized and deposited on seeded silicon and glass substrates by a hexamethylenetetramine (HMTA) - assisted hydrothermal method at low temperature (90 oC) with methenamine ((CH3)6N4), as surfactant and catalyst. The substrates were seeded with ZnO nanoparticles. The structure and morphology of the nanostructures were studied by means of x-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM), and scanning electron microscopy (SEM) techniques. Influence of the seed nanoparticle on the formation of the flower-like ZnO nanostructures is demonstrated. The influence of the organic oxygenated chains on the crystalline habit during the growth process is also observed.

description: We introduce PIRATE, a new remotely-operable telescope facility for use in research and education, constructed from 'off-the-shelf' hardware, operated by The Open University. We focus on the PIRATE Mark 1 operational phase where PIRATE was equipped with a widely- used 0.35m Schmidt-Cassegrain system (now replaced with a 0.425m corrected Dall Kirkham astrograph). Situated at the Observatori Astronomic de Mallorca, PIRATE is currently used to follow up potential transiting extrasolar planet candidates produced by the SuperWASP North experiment, as well as to hunt for novae in M31 and other nearby galaxies. It is operated by a mixture of commercially available software and proprietary software developed at the Open University. We discuss problems associated with performing precision time series photometry when using a German Equatorial Mount, investigating the overall performance of such 'off-the-shelf' solutions in both research and teaching applications. We conclude that PIRATE is a cost-effective research facility, and also provides exciting prospects for undergraduate astronomy. PIRATE has broken new ground in offering practical astronomy education to distance-learning students in their own homes.

description: High resolution seismic imaging methods are getting increasing attention in the exploration and development industry. Regularized Least Squares Prestack Migration (LSPSM) is one of these methods. Of the various methods of seismic migration, due to its low cost and flexibility of handling acquisition and topography irregularities, Kirchhoff migration has been the most frequently used method of migration in the industry for decades. LSPSM based on Kirchhoff migration is an effective method to attenuate acquisition footprint that result from sparseness or irregularities of seismic data sampling. LSPSM is a costly choice when compared to a conventional Kirchhoff migration. As shown in this study, the LSPSM equation cannot be solved efficiently using a standard multigrid method as it requires an explicit form of the corresponding Hessian matrix which needs to be diagonally dominant. It is shown that the Hessian of the LSPSM equation is a very large, dense, and diagonally non-dominant matrix. The performance of LSPSM is highly sensitive to the accuracy of the velocity model. Without a reasonably accurate velocity model, LSPSM cannot improve the quality of the migration image or do proper data reconstruction. This property provides a method to quantify the accuracy of the velocity model. Velocity analysis that is based on the migration CIGs can be extended to LSPSM CIGs. A coherency spectrum measured from LSPSM CIGs provides a velocity model that is accurate enough to give a high resolution image using LSPSM, and good data reconstruction in a few iterations. In a complementary study, the application of LSPSM in time lapse seismic analyses is investigated. Separate and joint LSPSM inversion of time lapse data gives a high resolution time lapse image which is less affected by different acquisition geometries of the baseline and monitor surveys. Data reconstruction of old and new surveys into a consistent new geometry will provide comparable prestack time lapse data sets. In conclusion, LSPSM is an effective method for high resolution imaging, with its advantages possibly outweighing its high cost.

description: Tumour-suppressors, such as PTEN and Rb, function to limit growth and proliferation. In post-mitotic peripheral sensory neurons, their knockdown may be utilized to promote regenerative growth. The goal of this thesis was to evaluate the effects of PTEN and Rb knockdown on peripheral nerve regeneration. Towards this goal I first addressed technical challenges, improving on a neuronal culture and immunostaining protocol. In assessing Rb knockdown I found increases in neuritic branching, but use of the PTEN inhibitor bpV(pic) was ineffective on neurite outgrowth, and therefore my results with combined Rb knockdown and PTEN inhibition were inconclusive. I also evaluated the phenotype of a PTEN conditional knockout mouse where PTEN is deleted from peripheral sensory neurons and found that they exhibited enlarged nerves with supernumerary myelinated axon profiles and a corresponding increase in SNAP amplitudes. Loss of phenotype was observed in a subsequent generation, pointing to complications in the Cre-lox conditional knockout system.

description: The very purpose of this study was to investigate the tools that are used by the government public relations departments and the challenges they encountered while using standard PR tools. Descriptive research design based study was conducted using both quantitative and qualitative research approaches; with data collected from a sample of public relations practitioners from governmental organizations in Agaro Town, western Ethiopia. Samples were selected based on simple random sampling and questionnaire was the principal data collection instrument. Following the return of the questionnaire, the data was entered into SPSS software version 21 for further processing, and the quantitative data was analyzed using percentages, frequency, mean, and standard deviations. The qualitative data was analyzed using thematic analysis. The findings of the study revealed that PR practitioners have adopted different media in reaching the external audience. They also partnered with the media to disseminate information, through community relationship programs and communicated the corporate social responsibilities of employees’. The findings revealed that political diffusion is affecting the practices of PR in the town; extreme media and public scrutiny; a lack of managerial support for PR practitioners; and a lack of training for PR practitioners about customers’ satisfaction, among other things were challenges investigated. Based on the major findings the researchers recommended that the government should spare adequate attention to help the PR practitioners use the right tools in the right place. The practitioners also should improve their commitment level to the customers’ base service so that they satisfy their public.

description: We report on our analysis of the VISTA Orion ZYJHKs photometric data (completeness magnitudes Z=22.6 and J=21.0mag) focusing on a circular area of 2798.4 arcmin^2 around the young sigma Orionis star cluster (~3Myr, ~352pc, solar metallicity). The combination of the VISTA photometry with optical, WISE and Spitzer data allows us to identify a total of 210 cluster member candidates with masses in the interval 0.25-0.004Msun, 23 of which are new planetary-mass object findings. These discoveries double the number of cluster planetary-mass candidates known so far. One object has colors compatible with a T spectral type. The cluster harbors about as many brown dwarfs (69, 0.072-0.012Msun) and planetary-mass objects (37, 0.012-0.004Msun) as very low-mass stars (104, 0.25-0.072Msun). Based on Spitzer data, we derive a disk frequency of ~40% for very low-mass stars, brown dwarfs, and planetary mass objects in sigma Orionis. The radial density distributions of these three mass intervals are alike: all are spatially concentrated within an effective radius of 12arcmin (1.2pc) around the multiple star sigma Ori, and no obvious segregation between disk-bearing and diskless objects is observed. Using the VISTA data and the Mayrit catalog, we derive the cluster mass spectrum (DeltaN/DeltaM ~ M^{-alpha}) from ~19 to 0.006Msun (VISTA ZJ completeness), which is reasonably described by two power-law expressions with indices of alpha=1.7+/-0.2 for M>0.35Msun, and alpha=0.6+/-0.2 for M<0.35Msun. The sigma Orionis mass spectrum smoothly extends into the planetary-mass regime down to 0.004Msun. Our findings of T-type sources (<0.004Msun) in the VISTA sigma Orionis exploration appear to be smaller than what is predicted by the extrapolation of the cluster mass spectrum down to the survey J-band completeness.

Pharmaceutical programs and social policy development: comparing Canada, Australia and the UK
Creators: name: Boothe, Katherine
Publisher: name: University of British Columbia
Year: 2010

description: Canada is the only OECD country that provides broad public health benefits but lacks a universal, nation-wide system for funding prescription drugs. This puzzle cannot be explained by the literature on national health insurance, which suggests that the tendency to consider all health services as a single policy has missed an important source of cross-national variation. How can we explain the lack of a major pharmaceutical program in Canada, in light of the country’s own extensive health system and the experience of almost all other welfare states? More generally, why do some countries adopt universal, comprehensive pharmaceutical programs, while others do not? To answer these questions, the study compares Canada to the UK and Australia using a process-tracing approach, and finds that the range of services in a country’s public health system is determined by the earliest decisions about how to approach policy development. Where institutional, ideological and electoral conditions allowed for large-scale change and all services were introduced simultaneously, countries tended to maintain the full scope of services. But where institutional barriers, ideological dissensus and low issue salience made radical change difficult, health programs were introduced incrementally, and policy development tended to stall after the first priority. Although incrementalism was initially less politically risky, it was also inherently limiting. Barriers to the introduction of services increased over time, and services that were initially lower priorities (such as pharmaceuticals in Canada) were pushed off the public agenda. In investigating this phenomenon, I provide specific mechanisms by which a more limited “path” of policy development becomes “dependent,” and argue that we must consider not only the role of ideas in policy making, but also the role of ideas over time. The study also investigates the implications of the approach to policy development for subsequent policy outcomes. It finds that factors that support the simultaneous adoption of a full range of health services also make it more difficult to retrench these services later on.

description: The pair production of Majorana neutrinos with transit magnetic moments from the annihilation of charged particles in colliding experiments is discussed using the Pauli interaction, through which the neutral neutrinos but with magnetic moments can be probed by photon. The pair of neutrinos with different flavors are produced due to the transit magnetic moment coupling. We discuss the correlations of flavors in pairs produced back-to-back in the center of mass frame, where the angular distribution peaks at $θ=π/2$ with respect to the beam direction. We demonstrate that the flavor mixing angle can be inferred by measuring the flavor correlation in pairs.

description: This thesis examines the social lives and subjectivity of domestic migrant vendors at a night market located at the urban rim of Nanjing city, China. The thesis asks what kinds of social connections (guanxi) are produced when migrant vendors try to adapt to city lives. The effective cultivation of guanxi is vital for migrant vendors, or household-based producers (getihu) to get a foothold and profit in the local market, particularly when general environs and local conditions brought about by contemporary urban transformations are unfavourable for these non-local petty entrepreneurs. By exploring the ways vendors (mainly men) make connections with local hooligans, grassroots government/local institutions as well as amongst themselves and with the other gender, this thesis argues that local terms such as hun (literally to get by, to scam or to muddle through) in Society (in Chinese shehui) precisely capture the subjectivity and sociality of these self-employed entrepreneurs. Society represents the fluid, complex social tapestry which entails riskiness and uncertainties rendered by migration, local conditions and business competitions. Hun entails a variety of tactics, ethics and masculinities and bears rich performative meanings when subjects are adapting to Society. Both hun and Society are crucial for understanding the subjectivity, gender and political identity of the self-employed rural migrants in contemporary China.
Diasporic Life, Images and Aspirations of Ethiopians in Ethiopian Diaspora Novels:
Creators: name: Melkie, Abraham
Publisher: name: Ethiopian Journal of Language, Culture and Communication
Year: 2023

description: Ethiopian Diasporas are the result of four major waves of migration since the late 1970s: persecution of oppositions, aliyahs of Ethiopian Jews, fear of persecution, and dispersion due to lack of economic prospects. This study revealed that Ethiopia is seen as a land of famine and Ethiopians as poverty-stricken, unrighteous, sub-human and barbaric people in four major destinations of Ethiopian Diaspora. The conclusions drawn based on these findings accordingly are: one, Ethiopia's image abroad is damaged almost incurably and the government must work hard to rebuild it. Two, diasporic life is not desirable contrary to the attitude Ethiopians at home presume it to be. Three, a larger section of Ethiopian migrants aspire to return back home.

description: We have carried out a detailed modeling of the dust Spectral Energy Distribution (SED) of the nearby, starbursting dwarf galaxy NGC 4214. A key point of our modeling is that we distinguish the emission from (i) HII regions and their associated photodissociation regions (PDRs) and (ii) diffuse dust. For both components we apply templates from the literature calculated with a realistic geometry and including radiation transfer. The large amount of existing data from the ultraviolet (UV) to the radio allows the direct measurement of most of the input parameters of the models. We achieve a good fit for the total dust SED of NGC 4214. In the present contribution we describe the available data, the data reduction and the determination of the model parameters, whereas a description of the general outline of our work is presented in the contribution of Lisenfeld et al. in this volume.

description: Context: The global size and spatial distribution of dust is an important ingredient in the structure and evolution of protoplanetary disks and in the formation of larger bodies, such as planetesimals. Aims: We aim to derive simple equations that explain the global evolution of the dust surface density profile and the upper limit of the grain size distribution and which can readily be used for further modeling or for interpreting of observational data. Methods: We have developed a simple model that follows the upper end of the dust size distribution and the evolution of the dust surface density profile. This model is calibrated with state-of-the-art simulations of dust evolution, which treat dust growth, fragmentation, and transport in viscously evolving gas disks. Results: We find very good agreement between the full dust-evolution code and the toy model presented in this paper. We derive analytical profiles that describe the dust-to-gas ratios and the dust surface density profiles well in protoplanetary disks, as well as the radial flux by solid material "rain out", which is crucial for triggering any gravity assisted formation of planetesimals. We show that fragmentation is the dominating effect in the inner regions of the disk leading to a dust surface density exponent of -1.5, while the outer regions at later times can become drift-dominated, yielding a dust surface density exponent of -0.75. Our results show that radial drift is not efficient in fragmenting dust grains. This supports the theory that small dust grains are resupplied by fragmentation due to the turbulent state of the disk.

description: How do firms adjust their innovation activities to their situational and contextual setting? The extant literature does not provide a clear answer to this question as the context moves away from high-tech industries and R&D based innovations. This theoretical gap is reflected in the managerial practice in form of hardship in managing innovation in “low-tech” industries and underestimating the non-R&D opportunities of innovation across industries. This dissertation intends to contribute to filling this gap through addressing the following research questions: 1) What is the role of industry characteristics in determining the firm's decision regarding innovation both in an active decision making environment and in reaction to performance shortfall problems? And 2) what are the firm-specific factors that contribute to a firm's innovativeness and approach to innovation specially as measured by non-R&D proxies? I use three different datasets and methods each building part of the puzzle to provide a clear picture. In the first essay, I investigate the industry and firm characteristics that lead to choice of R&D and non-R&D forms of innovation in response to problems and propose theoretical insights that I verify using data on financial activities of public firms. In the second essay, I conduct a meta-analysis of innovation publications that uncovers the importance of non-cash input (absorbed slack) to firms’ innovativeness and identify the setting that such input makes the most impact. Finally, in the third essay, I use unique data about innovation activities of Canadian public and private firms to distinctly study the innovation approaches of resource industries – as one of the neglected industries in the innovation literature – and investigate how innovation in these industries is induced, measured, and utilized.
Valence in Sidaama Reflexive and Reciprocal Constructions

description: This study focuses on Sidaama reflexive and reciprocal constructions in relation to verbal valence adjustment. The study aims at describing and analyzing how reflexive and reciprocal constructions are marked. It also examines how these constructions affect the syntactic and semantic valence of verbs. To attain the objectives, exhaustive primary and secondary data were obtained for primary and secondary data sources, respectively. To collect the secondary data, first, published and written materials were consulted since they can serve as sources of linguistic data and insight. Exhaustive primary data were collected from the native speakers of the native speakers via elicitation. To gather the primary data, the informants were asked to orally translate the Amharic sentences and word lists into Sidaama. Then the collected data were organized, phonemically transcribed (morphophonemic processes are taken into account) and glossed. Finally the data were translated and analyzed. Based on the data analysis, the study yielded the following findings. Sidaama marks reflexive and reciprocal constructions morphologically, syntactically,lexically or morphologically as well as syntactically. Morphological reflexive constructions decrease the syntactic valence of the verbs, whereas syntactic reflexive constructions do not affect the syntactic valence of the verb since the object slot is occupied by a reflexive pronoun. However, both morphological and syntactic reflexive constructions decrease the semantic valence of a verb. Because the action stated by the verb is not transmitted from one entity to another and as a result the verb semantically remains intransitive. As already stated, Sidaama marks reciprocal constructions lexically, morphologically or syntactically or morphologically and syntactically. Syntactic reciprocal constructions do not affect the valence of a verb since the verb remains transitive both syntactically and semantically. However, the syntactic valence is affected when reciprocation is encoded lexically and morphological since the object slot is left empty.

description: We propose a new mechanism for producing a Higgs boson mass near 125 GeV within the MSSM. By coupling the MSSM Higgs boson to a set of strongly interacting fields, large corrections to the Higgs quartic coupling are induced. Although the Higgs doublets do not participate in the strong dynamics, they feel the effects of the strongly coupled sector via (semi-)perturbative interactions. These same strong dynamics are also capable of generating the $μ$-term. Additionally, this strong sector is in the conformal window, which drives the couplings to an infrared fixed point and naturally generates model parameters of the appropriate size.

Building a Monument to the “Truth about War”: ISÔKO’s Monument in Rwanda and in Toronto

description: This thesis tests the limits of applied theatre production by examining performances of Colleen Wagner’s play The Monument by ISÔKO: The Theatre Source, an intercultural Canadian-Rwandan theatre company. I detail how ISÔKO challenged discourses that normalize the notion of forgiveness when they performed at makeshift theatres in Rwanda (2008-2011) and at the 2011 World Stage Festival in Toronto, Canada. I illustrate the radical potential of a Canadian play to provoke important discussions about citizenship and justice through the production of a utopian performative, but I expose the problem of voyeurism when an applied theatre company from a place of war performs a play about a post-genocide community at an international festival. ISÔKO’s Monument enabled productive social work on the World Stage, but only by refusing to produce utopia in performance. I conclude that a performance does not fit within the applied theatre rubric when it cannot gesture towards hope.

description: Τα αυτόνομα οχήματα που είναι ικανά να κινούνται και να δρούν στο χώρο χωρίς να απαιτείται καθοδήγηση ή τηλεχειρισμός, παρουσιάζουν σημαντικό ενδοαφέρον. Σκοπός της παρόυσας εργασίας είναι ο σχεδιασμός και η υλοποίηση ενός αυτοκινούμενου μηχατρονικού οχήματος, χειριζομένου μέσω ασύρματης επικοινωνίας, με δυνατότητες ιχνηλάτησης διαδρομής, αξιοποιώντας τις δυνατότητες ενός μικροελεγκτή. Η χρήση μικροελεγκτή απλοποιεί σε μεγάλο βαθμό την πολυπλοκότητα της κατασκευής του μηχατρονικού οχήματος. Περιορίζει τις ανάγκες επιπλέον ολοκληρωμένων κυκλωμάτων και καλωδιώσεων, η υλοποίηση είναι εύχρηστη και ο πειραματισμός γρήγορος. Όσο αφορά τους αλγόριθμους linetracking, ο PID έλεγχος ήταν πιο αξιόπιστος και γρήγορος. Η εφαρμογή αυτή ανέδειξε τις δυνατότητες της μηχατρονικής και των συναφών τεχνολογιών στην αυτόνομη κίνηση οχημάτων.

description: In this paper, we first prove the unique global strong solution with vacuum to the two dimensional nonhomogeneous incompressible MHD system, as long as the initial data satisfies some compatibility condition. As a corollary, the global existence of strong solution with vacuum to the 2D nonhomogeneous incompressible Navier-Stokes equations is also established. Our main result improves all the previous results where the initial density need to be strictly positive. The key idea is to use some critical Sobolev inequality of logarithmic type, which is originally due to Brezis-Wainger.

description: This thesis is about the Ok Tedi mine in Papua New Guinea. Throughout the literature on mining and communities, there is a split between the technical and the social. Technical mining – the engineering, environmental, planning and operations – do not ordinarily consider communities beyond the technical aspects of community relations – housing, employment, transport – rather approaching communities in a sanitised, corporate manner. There is plenty of discussion about environmental aspects of mine closure already, but it is important to have an extended discussion and create a space for debate about the roles of mining companies in developing sustainability plans that are for communities, not just the environments they exist in. The Ok Tedi mine has a unique institutional aspect that has grown with the mine – the Ok Tedi Mining Complex – which is inhabited by various governmental and non-governmental organisations. The mine closure and sustainability planning process under the OTMC is unique to Ok Tedi mine, as there is no other mine in PNG that is guided by the same legislation, norms, and cultural frameworks. The OTMC is dominated by the stakeholder relationships of the organisations under its auspices, and the outcomes of these relationships directly affect the outcomes of development planning. This thesis examines the development of the OTMC, and assesses the way it shaped the relationship between the main stakeholder organisations - Ok Tedi Mining Limited, PNG Sustainable Development Program Ltd., PNG national government, Ok Tedi Development Foundation, communities of the Community Mine Continuation Agreement regions, Fly River Provincial Government – has influenced the development of mine closure as a function of sustainability planning, the ongoing funding streams available for programs, and the development and implementation of programs aimed at encouraging sustainable livelihoods. This involves two case studies of livelihood promotion programs – Agriculture and Food Security, and Artisanal and Small Scale Mining. The dissertation is an original contribution to knowledge because there has been no systematic examination of the Ok Tedi Mining Complex as an institution, and there have been significant developments transforming the way that the stakeholder organisations relate to each other concerning mine closure and sustainability planning.
The role of leptin in the regulation of glucose homeostasis
Creators: name: Levi, Jasna
Publisher: name: University of British Columbia

description: The fat derived hormone leptin plays a crucial role in the normal maintenance of body weight and energy expenditure, as well as glucose homeostasis. Low doses of exogenous leptin administered to leptin deficient ob/ob mice are able to reverse the hyperinsulinemia and hyperglycemia without altering body composition. As leptin has the ability to directly suppress insulin secretion from ß-cells, we hypothesise that in the absence of leptin signalling, unregulated insulin secretion leads to hyperinsulinemia which in turn leads to increased adipogenesis and insulin resistance, ultimately culminating in the development of type 2 diabetes in this mouse model. To test this hypothesis we induced an acute state of leptin deficiency with a PEGylated mouse leptin antagonist (PEG-MLA) to determine the hierarchy of leptin action. Metabolic analysis by indirect calorimetry showed that PEG-MLA treatment resulted in increased food intake and respiratory quotient without altering body composition or energy expenditure. These changes in energy balance were accompanied with increased fasting, and glucose stimulated insulin levels. PEG-MLA treated mice also displayed decreased whole-body insulin sensitivity, elevated endogenous hepatic glucose production (HPG), and impaired insulin mediated suppressed of HPG as determined by euglycemic-hyperinsulinemic clamps. Overall, these findings demonstrate that leptin signalling is important in regulating insulin secretion, and that changes in insulin sensitivity occur prior to changes in body composition and energy expenditure in a state of acute leptin deficiency. It has been recently shown that the liver derived, leptin regulated insulin-like growth factor binding protein-2 (IGFBP-2) is responsible for the anti-diabetic effect of leptin in ob/ob mice. We investigated the mechanism by which leptin regulates IGFBP-2 levels. ob/ob mice with attenuated hepatic leptin signalling or a subdiaphragmatic vagotomy were utilized to determine if leptin acts directly on the liver or centrally to increase plasma IGFBP-2. Our results show that while leptin is able to increase plasma IGFBP-2 levels in ob/ob mice in a dose dependent manner, the mechanism does not involve heptic leptin signalling or vegal efferents and remains to be elucidated.
