description: We critically (re)examine the associated production process of a $J/ψ$ meson plus an open charm hadron at the LHC in the proton-proton ($pp$) and proton-lead ($p{\rm Pb}$) collisions. Such a process is very intriguing in the sense of tailoring to explore the double parton structure of nucleons and to determine the geometry of partons in nuclei. In order to interpret the existing $pp$ data with the LHCb detector at the center-of-mass energy $\sqrt{s}=7$ TeV, we introduce two overlooked mechanisms for the double parton scattering (DPS) and single parton scattering (SPS) processes. Besides the conventional DPS mode, where the two mesons are produced almost independently in the two separate scattering subprocesses, we propose a novel DPS mechanism that the two constituent (heavy) quarks stemming from two hard scatterings can form into a composite particle, like the $J/ψ$ meson, during the hadronization phase. However, it turns out the corresponding contribution is small in $J/ψ+c\bar{c}$ hadroproduction. On the contrary, we point out that the resummation of the initial state logarithms due to gluon splitting into a charm quark pair is crucial to understand the LHCb measurement, which was overlooked in the literature. We perform a proper matching between the perturbative calculations in different initial-quark flavor number schemes, generically referring to the variable flavor number scheme. The new variable flavor number scheme calculation for the process strongly enhance the SPS cross sections, almost closing the discrepancies between theory and experiment. Finally, we present our predictions for the forthcoming LHCb measurement in $p{\rm Pb}$ collisions at $\sqrt{s_{NN}}=8.16$ TeV. Some interesting observables are exploited to set up the control regions of the DPS signal and to probe the impact-parameter dependent parton densities in lead.

description: E. Bach, following an idea of T. Itoh, has shown how to build a small set of numbers modulo a prime p such that at least one element of this set is a generator of $\pF{p}$\cite{Bach:1997:sppr,Itoh:2001:PPR}. E. Bach suggests also that at least half of his set should be generators. We show here that a slight variant of this set can indeed be made to contain a ratio of primitive roots as close to 1 as necessary. We thus derive several algorithms computing primitive roots correct with very high probability in polynomial time. In particular we present an asymptotically $O^{\sim}(\sqrt{\frac{1}ε}log^1.5(p) + \log^2(p))$ algorithm providing primitive roots of $p$ with probability of correctness greater than $1-ε$ and several $O(log^α(p))$, $α\leq 5.23$ algorithms computing "Industrial-strength" primitive roots with probabilities e.g. greater than the probability of "hardware malfunctions".

description: We have conducted a systematic and comprehensive monitoring programme of the Type Ia supernova 2000cx at late phases using the VLT and HST. The VLT observations cover phases 360 to 480 days past maximum brightness and include photometry in the BVRIJH bands, together with a single epoch in each of U and Ks. While the optical bands decay by about 1.4 mag per 100 days, we find that the near-IR magnitudes stay virtually constant during the observed period. This means that the importance of the near-IR to the bolometric light curve increases with time. The finding is also in agreement with our detailed modeling of a Type Ia supernova in the nebular phase. In these models, the increased importance of the near-IR is a temperature effect. We note that this complicates late-time studies where often only the V band is well monitored. In particular, it is not correct to assume that any optical band follows the bolometric light curve at these phases, and any conclusions based on such assumptions, e.g., regarding positron-escape, must be regarded as premature. A very simple model where all positrons are trapped can reasonably well account for the observations. The nickel mass deduced from the positron tail of this light curve is lower than found from the peak brightness, providing an estimate of the fraction of late-time emission that is outside of the observed wavelength range. Our detailed models show the signature of an infrared catastrophe at these epochs, which is not supported by the observations.

description: To investigate the origin of elevated globular cluster abundances observed around Ultra-Diffuse Galaxies (UDGs), we simulate globular cluster populations hosted by UDGs formed through tidal heating. Specifically, globular cluster (GC) formation is modeled as occurring in regions of dense star formation. Because star-formation-rate-densities are higher at high redshift, dwarf galaxies in massive galaxy clusters, which formed most of their stars at high redshift, form a large fraction of their stars in globular clusters. Given that UDGs formed through environmental processes are more likely to be accreted at high redshift, these systems have more GCs than non-UDGs. In particular, our model predicts that massive UDGs have twice the GC mass of non-UDGs of similar stellar mass, in rough agreement with observations. Although this effect is somewhat diminished by GC disruption, we find that the relationship between GC mass fraction and cluster-centric distance, and the relationship between GC mass fraction and galaxy half-light radius are remarkably similar to observations. Among our model objects, both UDGs and non-UDGs present a correlation between halo mass and GC mass, although UDGs have lower dynamical masses at a given GC mass. Furthermore, because of the effectiveness of GC disruption, we predict that GCs around UDGs should have a more top heavy mass function than GCs around non-UDGs. This analysis suggests that dwarfs with older stellar populations, such as UDGs, should have higher globular cluster mass fractions than objects with young stellar populations, such as isolated dwarfs.

description: We focus our study in the opportunities that exist in investment for conservation of biodiversity in tropical countries. It allows a natural and multiple benefits of mitigation of climate change as well as addressing the global environment problem of biodiversity loss. We observe that the short implementation in Australia of the “carbon tax” during 2012 and 2013 that was dismantle in the Federal Elections of 2013 was inadequately informed to the general public. And, it was seen and criticised by them as being a one party unilateral initiative and the mitigation tools such as reduction of energy consumption using non-natural means, such as more products were rejected by the majority of the population. It was a contradictory relation of less climate change with more material production. We hypothesise that the support and understanding of the Australians will provide a support to develop policy design that include this component in a long term strategy for Australia, including the development of investment in biodiversity conservation in tropical forest countries as a better alternative than man-made carbon sequestration or strategies. A choice modelling experiment was designed with a sample of 100 University students from Melbourne and Sydney. It present a hypothetical scenario about a hypothetical investment program to maintain the resilience of the Amazon forest ecosystem. The results presented show the trade-offs of the attributes assigned to a public program of investment in biodiversity conservation in Peru. It will provide results that contribute to build sound policies in the framework of current consensus in the Paris 2015 agreement.
Critical Exponents of the O(N)-symmetric $ϕ^4$ Model from the \boldmath{\large{ $\varepsilon^7$}} Hypergeometric-Meijer Resummation

description: We extract the $\varepsilon$-expansion from the recently obtained seven-loop $g$-expansion for the renormalization group functions of the $O(N)$-symmetric model. The different series obtained for the critical exponents $ν,\ ω$ and $η$ have been resummed using our recently introduced hypergeometric-Meijer resummation algorithm. In three dimensions, very precise results have been obtained for all the critical exponents for $N=0,1,2,3$ and $4$. To shed light on the obvious improvement of the predictions at this order, we obtained the divergence of the specific heat critical exponent $α$ for the $XY$ model. We found the result $-0.0123(11)$ which is compatible with the famous experimental result of -0.0127(3) from the specific heat of zero gravity liquid helium superfluid transition while the six-loop Borel with conformal mapping resummation result in literature gives the value -0.007(3). For the challenging case of resummation of the $\varepsilon$-expansion series in two dimensions, we showed that our resummation results reflect a significant improvement to the previous six-loop resummation predictions.

description: This thesis concludes that a 100% renewable energy system throughout the nine populated islands of Cape Verde is technically feasible. 2012 was chosen as the base year due to availability of consistent data. Values of 2012 and projections from the Ministry of Energy were taken to predict the size of the energy sector by 2020 and 2030. In consequence, the results are presented for these two years. Besides, the thesis is built upon a thorough literature review which provided the integral equations and processes for the assessment of potential. Furthermore, this study has been supported by the expertise of ECREEE staff as well as other experts in the field. In a first step the theoretical overall technical possibility of deploying 100% RE has been established by computing the required land area for solar PV respectively the number of wind turbines to supply the annual energy demand. It was found that Cape Verde can accommodate sufficient facilities either relying on 100% wind or solar PV. In a second step, an individual energy mix for each of the nine islands has been derived. The approach was based on a numerical analysis of hourly values for loads and the wind and solar resource. Additionally, two different energy storage schemes were applied, without which no 100% renewable electricity system can succesfully work. For this study, energy storage was designed to sustain a 1,5 day respectively a 1 week period without newly produced energy. Moreover, four distinct ways of storing excess energy were considered. All islands proved to be able to accommodate power-to-gas energy storage while only individual islands have been selected for battery, thermal energy and pumped hydro storage. The outcome indicates that solar PV is the most reliable resource in two thirds of all scenarios while wind only plays a vital role for two of the nine islands. The excess energy produced by both scenarios (1,5DS and 1WS) is extensive, however, especially for the shorter storage scheme. Finally, all scenarios have been put in a financial context. It has been deduced that costs will be vast and might prove to be an obstacle in achieving 100% RE penetration. Among all storage scenarios assessed power-to-gas storage is the most attractive one in terms of costs. Furthermore, larger sized energy storage schemes turned out to be the least cost option.

description: Potential effects of alleged monopsony pricing of farm food products by supermarkets on farm product prices, quantities, incomes and land values are assessed relative to competitive behaviour. A comparative static equilibrium model is used. For export products and the few import competing products, the effective food input supply curve facing the supermarkets is close to perfectly elastic and this limits monopsony behaviour. For the non-traded food products, the ease of reallocating the fixed supply of aggregate agricultural land between traded and non-traded food products means a highly elastic food supply function for non-traded food products, and very limited monopsony effects.

description: Polarization observations at 21cm and 18cm towards the local Taurus molecular cloud complex were made with the Effelsberg 100-m telescope. Highly structured, frequency-dependent polarized emission features were detected. We discuss polarization minima with excessive rotation measures located at the boundaries of molecular clouds. The multi-frequency polarization data have been successfully modeled by considering magneto-ionic Faraday screens at the surface of the molecular clouds. Faraday rotated background emission adds to foreground emission towards these screens in a different way than in its surroundings. The physical size of the Faraday screens is of the order of 2 pc for 140 pc distance to the Taurus clouds. Intrinsic rotation measures between about -18 rad/m2 to -30 rad/m2 are required to model the observations. Depolarization of the background emission is quite small (compatible with zero), indicating a regular magnetic field structure with little turbulence within the Faraday screens. With observational constraints for the thermal electron density from H-alpha observations of less than 0.8 cm^-3 we conclude that the regular magnetic field strength along the line of sight exceeds 20 muG. We discuss some possibilities for the origin of such strong and well ordered magnetic fields. The modeling also predicts a large-scale, regularly polarized emission in the foreground of the Taurus clouds which is of the order of 0.24 K at 21cm. This amount of synchrotron emission is clearly excessive when compared to previous estimates of the local synchrotron emissivity.

Die Berücksichtigung von Gewinn- und Verlustrechnungen stellt eine Kontroverse dar, da die Finanzierung der öffentlichen Hochschulen von staatlicher Seite erfolgt und ein Gewinn nicht angestrebt wird. Das Ziel der vorliegenden Arbeit ist, die Berichterstattung österreichischer und deutscher Hochschulen zu analysieren sowie auf Probleme und Verbesserungsvorschläge hinzuweisen. Insbesondere wird die Frage diskutiert, ob die kaufmännische Rechnungslegung von den öffentlichen Hochschulen ohne Modifizierung übernommen werden kann. Dazu werden die Jahresberichte der deutschen Universität in Heidelberg und in Lüneburg, sowie der österreichischen Universität Wien und der Wirtschaftsuniversität (WU) untersucht. Die Analyse der Berichte zeigte, dass die Universitäten in Bezug auf die Berichterstattung unterschiedlich vorgehen und es zu einem Chaos aufgrund der Einbeziehung verschiedene Elemente kommen kann. Die Abschreibung, die Miteinbeziehung der Bibliotheksbestände, sowie die Ausweisung eines Gewinns bei Institutionen, die nicht als Ziel den Gewinn verfolgen, zeigte, dass die Gewinn- und Verlustrechnung als solche nicht in die Hochschulrechnung übernommen werden kann und als Ergebnis eine Verwirrung der Adressaten hat. Folglich wären insbesondere unterschiedliche Leistungsparameter als Qualitätsindikatoren einzubeziehen sowie Berichte wie die Wissensbilanz oder der Leistungsbericht als Quellen verwendbarer, zuverlässige und nützliche Informationen bereitzustellen. Staat der Gewinn- und Verlustrechnung, sollte eine Wertänderungsrechnung eingeführt werden, sowie eine Finanzrechnung. Weiterführend könnte der Staat in Kooperation mit den Hochschulen die Methode zur Implementierung einer vergleichbaren Hochschulrechnung entwickeln, basierend auf den Qualitätskriterien des Produkts Wissen (Küpper, 2000b, S. 365 f.).

description: One of the most terrifying words nowadays is COVID-19 (short for Corona Virus Disease-2019) even more devastating is its effect on the total world where people are still shocked under its killing spree. The rate of mortality and the number of cases is going skywards, with no sign of respite. In this 21st century era we are at an advantage because of the different technological advancements at our disposal. Scientific discoveries and innovations are increasing along with it the viruses are also evolving which is one of the major concerns in today’s world. In this paper we will try to peep deeper into the COVID-19 and epidemiology that should be known relating to it. The science behind its replication and virulence efficiency has been dealt at some length along with transmission efficiency. Favorable conditions required for the virus’ replication has also been discussed to some extent. More emphasis has been given to explain the anti-pandemic strategies, which explain how to curb its spread and the different mechanisms that are explored to treat it. Multiple drugs and vaccines that are undergoing trials have also been presented by us. This paper is our conscious bit of effort to put some stress on making people aware of the seriousness of the matter at stake and deciphering Coronavirus.

description: This research is a study on the design features and policy measures for market stabilization in the KETS, including the potential issues and available recommendations at the present. It aims to contribute to the successful settlement and development of the KETS as a pillar strategy of environment policy in Korea. Furthermore, the study on the uniquness of the market stabilzation measures in the KETS could provide a another exemplar for the developing countries to prepare the launch of the ETS in near future. In the Chapter 2, the development process of the KETS (Charter 2-1) is chronologically described as background knowledge. Together with the national emission reduction target, the cap in the KETS is reviewed. Especially, the characteristic of cap coverage is discussed on the perspective of the market liquidity. (Chapter 2-2). The next is to look through the main characteristics of the KETS for market stabilization, which will help understand the policy measures for the market flexibility in the KETS.(Chapter 2-3) For this study, it is necessary to benchmark strategically the volatility of price spike and crash of the EU ETS and to learn the lessons from the experiences which the EU ETS has gone through over the almost past 10 years. The strategic benchmarking includes the performance evaluation (Chapter 3- 1) and the review on the current reform proposal for revitalization of the driving efficiency in the EU ETS (Chapter 3-2). Next the lessons learned through strategic benchmarking on the EU ETS (Chapter 3-3) is summarized for the contribution to the KETS. Finally, in chapter 4, the comparison of market stabilization between KETS and EU ETS (Chapter 4-2) is followed by the previous reform options of the EU ETS (Chapter 4-1) which is very useful to gain the comprehensive perspective for market stabilization measures. The current status of the KETS and the MSM actions took recently by the Government are handled in Chapter 4-3. In conclusion, the available policy recommendations for the KETS at the present stage are presented.

description: Changes to institutional structures and management of Australian agricultural R&D may have affected research performance. These changes have included shifts in institutional arrangements, increased focus on research management and accountability, integration of research effort, and greater involvement in research by producers. We see these changes as generally beneficial to the delivery of more relevant outputs and improved impacts. We make comment on measuring trends in the performance of R&D and the methods and findings of some Australian economic evaluations of research investment, using both top down and bottom up approaches. We then suggest a wider framework for evaluating R&D performance and agricultural R&D investment.

description: The signature of superfluidity in bosonic systems is a sound wave-like spectrum of the single particle excitations which in the case of strong interactions is roughly temperature independent. In fermionic systems, where fermion pairing arises as a resonance phenomenon between free fermions and paired fermionic states (examples are: the atomic gases of lithium or potassium controlled by a Feshbach resonance, polaronic systems in the intermediary coupling regime, d-wave hole pairing in the strongly correlated Hubbard system), remnants of such superfluid characteristics are expected to be visible in the normal state. The single particle excitations maintain there a sound wave like structure for wave vectors above a certain q_{min}(T) where they practically coincide there with the spectrum of the superfluid phase for T

Subjects: subject: Multi-Attribute search
subject: Optimal stopping time
subject: Jointly Distributed Attributes

description: A usual assumption in the multi-attribute search literature is independent distribution of attributes. This assumption is necessary for the tractability of the model. However, in reality many economic search problems show some degree of correlation among the attributes, i.e., by searching an attribute the decision maker not only resolves the uncertainty with regards to that attribute but also updates her beliefs about the distribution of other values. Furthermore, unlike it is usually assumed the decision maker's utility function does not need to be linear in all attributes, in fact, in most cases it is sensible to consider other functional forms. The search order is thus decided based on the marginal utility and informativeness of each attribute. In this thesis, I introduce a simpli ed search model where the decision maker seeks to choose between two objects which are described by their two attributes. These attributes are assumed to be jointly distributed according to a distribution function known by the decision maker. Moreover, I will try to analyze the optimal search and stopping rule.

description: We investigate two approaches to derive the proper Floquet-based quantum-classical Liouville equation (F-QCLE) for laser-driven electron-nuclear dynamics. The first approach projects the operator form of the standard QCLE onto the diabatic Floquet basis, then transforms to the adiabatic representation. The second approach directly projects the QCLE onto the Floquet adiabatic basis. Both approaches yield a form which is similar to the usual QCLE with two modifications: 1. The electronic degrees of freedom are expanded to infinite dimension. 2. The nuclear motion follows Floquet quasi-energy surfaces. However, the second approach includes an additional cross derivative force due to the dual dependence on time and nuclear motion of the Floquet adiabatic states. Our analysis and numerical tests indicate that this cross derivative force is a factitious artifact, suggesting that one cannot safely exchange the order of Floquet state projection with adiabatic transformation. Our results are in accord with similar findings by Izmaylov et al., who found that transforming to the adiabatic representation must always be the last operation applied, though now we have extended this result to a time-dependent Hamiltonian. This paper and the proper derivation of the F-QCLE should lay the basis for further improvements of Floquet surface hopping.

description: Bosnia and Herzegovina is a country facing many challenges on its path to become an EU member. One of these challenges is waste management. As a future candidate for the EU, Bosnia and Herzegovina will have to transpose and implement the Chapter 27: Environment, which concerns waste management. The goal of this thesis is to evaluate the present situation and give suggestions in order to improve future waste management system in the country. Due many problems with the data collection and evidencing of waste, it is hard to evaluate the present situation. The main question of this thesis is whether the goals of waste management are fulfilled by current waste management system? Also are these goals in harmony with EU? And, is the current legislation effective in providing framework for waste management? I have compared the goals of EU, Austria and Bosnia and Herzegovina to come to the conclusion that in Bosnia and Herzegovina there is only one goal; protection of human health and environment, which in my opinion is a suitable goal for the country. Also, I have compared the legislative framework of BiH and Austria and came to conclusion that for BiH, it does not provide appropriate framework for effective waste management. In order to answer the main question of thesis, I had to evaluate the current WM system. This was done using MFA and comparing the results of the research with the goals of WM. The results show that BiH is very far from fulfilling the goal of protection of human health and environment. The means for reaching this goal are not used appropriately and much harm is currently being done to environment and public health. My conclusion is that, having in mind current political and economic situation, the country needs to focus on the improvement of landfilling rather than the prevention of waste trough building regional waste management centers. Improvement in Landfilling is priority. This will solve major problems of waste management in the country, some of which are no appropriate treatment of waste, landfilling untreated waste, landfills which are not sanitary and non-evidencing of waste flows and lack of information and data on waste.

description: Maximisation of aggregate recreational hunter benefits involves managing both the prey and the hunter. The biology of game animals, and hence the supply side of the management situation, is reasonably well understood, but there is relatively little information on the demand side. On public lands, where there is no market to signal the quality of the hunting experience the game manager has little guidance on how to allocate the resource amongst individual hunters. In New Zealand, there is no attempt to do so. While seeing and killing game are known to enhance individual hunters’ benefits, the allocation of the resource across hunters raises the prospect of limiting individual hunter harvests, normally enacted through a bag limit. The benefits of doing so are dependent upon the marginal benefits of harvest for different hunters. The relationship between hunter satisfaction and the number of animals killed is explored using data from a longitudinal study of a large group of deer hunters. Latent class models of satisfaction outperform random parameters models and identify heterogenous groups of hunters whose satisfaction is differentially dependent on game sightings and harvest. Personal attributes and hunter motivations help explain some of these differences. Heterogenous and rapidly diminishing marginal satisfaction present a strong case for management of at least part of the open-access New Zealand red deer herd to enhance social welfare by increasing the number of hunters harvesting a deer rather than going home empty-handed.
Factors associated with mothers’ protection of their children from environmental tobacco smoke

Publisher: name: University of British Columbia

description: Children’s exposure to tobacco smoke is known to have adverse health effects, yet 200,000 Canadian children are still being exposed to tobacco smoke in their homes every day. A cross-sectional descriptive study was conducted to identify factors associated with whether mothers/primary care givers provide a smoke free environment for their children and the stage the mothers/primary care givers were in, in relation to their decision to adopt the precaution of ensuring people do not smoke around their children. Data were collected from 571 surveys sent home with kindergarten children in two prairie city school divisions. Mothers or primary care givers completed the survey. In the bivariate analysis, significant factors associated with providing a smoke free environment included education of the mother, number of friends and family who smoke, living with a partner, being a stay at home mother and being a nonsmoker. The strongest predictor in the multivariate logistic regression was the mother’s/primary care giver’s self-efficacy related to providing a smoke free environment. When mothers/primary care givers had high self-efficacy scores they were more likely to provide a smoke free environment, regardless of smoking status. One surprising finding was that when other variables were controlled for, having a higher education was less likely to be associated with always providing a smoke free environment. Being in an advanced stage of the precaution adoption process, "deciding to always provide a smoke free environment," was least likely when mothers/primary care givers had more friends and family who smoke, a lower self-efficacy, and a lower knowledge level of the effects of environmental tobacco smoke. The findings from this study expand our understanding of factors associated with mothers/primary care givers who do not always provide a smoke free environment for their children. Most importantly, modifiable factors are associated with the decision-making process and the action of providing a smoke free environment.

description: We model favoritism with an imperfect monitoring infinitely repeated game. We find that favoritism is driven by players trading favors over time. We show that favoritism is harder to maintain in larger groups, group mem- bers increase their payoff at the expense of others, and favoritism is easier to sustain in imperfect monitoring case compared to perfect monitoring. We also prove that for our game the Folk theorem does not hold if the number of players is 4, and we impose a restriction to the parameters.

description: Determining the value of legumes as soil-fertility amendments can be challenging, yet this information is required to guide public policy and to incentivise prescribed land-management practices such as conservation agriculture. We apply a directional distance function to data from Malawi, to estimate shadow prices for symbiotic nitrogen and the technical efficiency for mixed maize-legume production systems. The shadow prices reflect the trade-off between fertiliser-nitrogen and symbiotic-nitrogen required to achieve a given quantity of output. Our results reveal considerable technical inefficiency in the production system. The estimated shadow prices vary across farms and are, on average, higher than the reference price for commercial nitrogen. Our results suggest that it would be beneficial to redesign the current price-support programs that subsidise chemical fertilisers and indirectly crowd-out organic soil amendments such as legumes.
Dynamical robustness of topological end states in nonreciprocal Su-Schrieffer-Heeger models with open boundary conditions

description: For non-Hermitian quantum models, the dynamics is apparently not reflected by the static properties, e.g., the complex energy spectrum, because of the nonorthogonality of the right eigenvectors, the nonunitarity of the time evolution, the breakdown of the adiabatic theory, etc., but in experiments the time evolution of an initial state is commonly used. Here, we pay attention to the dynamics of an initial end state in nonreciprocal Su-Schrieffer-Heeger models under open boundary conditions, and we find that it is dynamically more robust than its Hermitian counterpart, because the non-Hermitian skin effect can suppress the part leaking to the bulk sites. To observe this, we propose a classical electric circuit with only a few passive inductors and capacitors, the mapping of which to the quantum model is established. This work explains how the non-Hermitian skin effect enhances the robustness of the topological end state, and it offers an easy way, via the classical electric circuit, of studying the nonreciprocal quantum dynamics, which may stimulate more dynamical studies of non-Hermitian models in other platforms.

Tubuan : history, tradition, and identity among the Tolai of Papua New Guinea
Creators: name: Tateyama, Hirokuni
Publisher: name: University of British Columbia
Year: 2010

description: This dissertation examines identity formation and transformation among the Tolai of Papua New Guinea through a historically grounded ethnographic analysis of the tubuan, a masked ritual figure which they generally regard as a prime symbol of their "traditional" culture. Much has been written about contemporary constructions of tradition in the Pacific. It has been suggested that people constitute identities by articulating notions of tradition in opposition to what is considered "Western" or "modern"---particularly church, state, and business. Tolai do distinguish their "traditional" culture from what they refer to as lotu (church), matanitu (government), and bisnis (business), but their constructions of tradition are often situated within these three separate yet closely intertwined institutions, which were originally introduced from outside but which they have made their own. This is most clearly evidenced by the deployment of the tubuan in "modern" settings, such as church celebrations, state functions, and tourism events. In the dissertation, I explore historical dimensions of the contemporary use of the tubuan in the institutional contexts of lotu, matanitu, and bisnis by paying particular attention to specific political circumstances in which Tolai negotiated problematic relations between these indigenous and exogenous forms. I show how Tolai maintained the institution of the tubuan, which was a vehicle for social reproduction, while eagerly appropriating new institutions; how Tolai came to see the tubuan as a prime symbol of their "traditional" culture through their power struggles with European colonizers; and how Tolai have used the tubuan to reproduce or reshape power relations within their society or country that have been manifested since national independence in 1975. The appearance of the tubuan in "modern" settings, which emphasizes the continued relevance of the "traditional" values it embodies to contemporary Tolai life, helps Tolai visualize a distinct Tolai identity that combines and synthesizes seemingly antithetical themes---an identity that challenges a simplistic dichotomy between tradition and modernity that is still perpetuated in ethnographic writing.

description: Rescue robots are expected to carry out reconnaissance and dexterity operations in unknown environments comprising unstructured obstacles. Although a wide variety of designs and implementations have been presented within the field of rescue robotics, embedding all mobility, dexterity, and reconnaissance capabilities in a single robot remains a challenging problem. This paper explains the design and implementation of Karo, a mobile robot that exhibits a high degree of mobility at the side of maintaining required dexterity and exploration capabilities for urban search and rescue (USAR) missions. We first elicit the system requirements of a standard rescue robot from the frameworks of Rescue Robot League (RRL) of RoboCup and then, propose the conceptual design of Karo by drafting a locomotion and manipulation system. Considering that, this work presents comprehensive design processes along with detail mechanical design of the robot's platform and its 7-DOF manipulator. Further, we present the design and implementation of the command and control system by discussing the robot's power system, sensors, and hardware systems. In conjunction with this, we elucidate the way that Karo's software system and human-robot interface are implemented and employed. Furthermore, we undertake extensive evaluations of Karo's field performance to investigate whether the principal objective of this work has been satisfied. We demonstrate that Karo has effectively accomplished assigned standardized rescue operations by evaluating all aspects of its capabilities in both RRL's test suites and training suites of a fire department. Finally, the comprehensiveness of Karo's capabilities has been verified by drawing quantitative comparisons between Karo's performance and other leading robots participating in RRL.

description: We present spectroscopic VLT/UVES observations of two emerging supernovae, the Type Ia SN 2001el and the Type II SN 2003hn, in the spiral galaxy NGC 1448. Our high resolution and high signal-to-noise spectra display atomic lines of Ca II, Na I, Ti II and K I in the host galaxy. In the line of sight towards SN 2001el, we also detect over a dozen diffuse interstellar bands (DIBs) within NGC 1448. These DIBs have strengths comparable to low reddening galactic lines of sight, albeit with some variations. In particular, a good match is found with the line of sight towards the sigma type diffuse cloud (HD 144217). The DIBs towards SN 2003hn are significantly weaker, and this line of sight has also lower sodium column density. The DIB central velocities show that the DIBs towards SN 2001el are closely related to the strongest interstellar Ca II and Na I components, indicating that the DIBs are preferentially produced in the same cloud. The ratio of the 5797 and 5780 DIB strengths (r~0.14) suggests a rather high UV field in the DIB environment towards SN 2001el. We also note that the extinction estimates obtained from the sodium lines using multiple line fitting agree with reddening estimates based on the colors of the Type Ia SN 2001el.

description: We study systematically the scattering processes and the conductance spectra in nodal-line semimetalsuperconductor junctions using the extended Blonder-Tinkham-Klapwijk theory. The coexistence of peculiar quadruple reflections are found, which are the specular normal reflection, the retro-normal reflection, the specular Andreev reflection and the retro-Andreev reflection. The incident angle dependence and the quasiparticle energy dependence of the double normal reflections and the double Andreev reflections are investigated under various values of parameters such as the interfacial barrier height, the chemical potentials, and the orbital coupling strength. It is found that the appearance and the disappearance of the reflections and their magnitudes can be controlled through tuning these parameters. The scattering mechanism for the reflections are analyzed in details from the viewpoint of the band structure. We also investigate the conductance spectra for the junctions, which show distinctive features and strong anisotropy about the orientation relationships of the nodal line and interface. The unique scattering processes and conductance spectra found in the junctions are helpful in designing superconducting electronic devices and searching for the nodal line in materials experimentally.
