Delegation of Authority as an Optimal (In)Complete Contract
Creators: name: Roider, Andreas
Publisher: name: Universität Regensburg
Year: 2006
Subjects: subject: 330 Wirtschaft

description: This paper contributes to the literature on the foundations of incomplete contracts. In a holdup framework, we provide two sets of conditions under which simple delegation of authority is the solution to the complete-contracting problem. In cases where overinvestment can be ruled out, delegation is optimal if the payoffs of the parties satisfy certain separability conditions. If overinvestment might be an issue, delegation (possibly with restricted competencies) is optimal if additionally some continuity requirements are met. The paper also contributes to the literature on delegation, where such replication results have previously been derived in settings with asymmetric information.
Phase Behavior of Colloidal Superballs: Shape Interpolation from Spheres to Cubes

description: The phase behavior of hard superballs is examined using molecular dynamics within a deformable periodic simulation box. A superball's interior is defined by the inequality $|x|^{2q} + |y|^{2q} + |z|^{2q} \leq 1$, which provides a versatile family of convex particles ($q \geq 0.5$) with cube-like and octahedron-like shapes as well as concave particles ($q < 0.5$) with octahedron-like shapes. Here, we consider the convex case with a deformation parameter q between the sphere point (q = 1) and the cube (q = 1). We find that the asphericity plays a significant role in the extent of cubatic ordering of both the liquid and crystal phases. Calculation of the first few virial coefficients shows that superballs that are visually similar to cubes can have low-density equations of state closer to spheres than to cubes. Dense liquids of superballs display cubatic orientational order that extends over several particle lengths only for large q. Along the ordered, high-density equation of state, superballs with 1 < q < 3 exhibit clear evidence of a phase transition from a crystal state to a state with reduced long-ranged orientational order upon the reduction of density. For $q \geq 3$, long-ranged orientational order persists until the melting transition. The width of coexistence region between the liquid and ordered, high-density phase decreases with q up to q = 4.0. The structures of the high-density phases are examined using certain order parameters, distribution functions, and orientational correlation functions. We also find that a fixed simulation cell induces artificial phase transitions that are out of equilibrium. Current fabrication techniques allow for the synthesis of colloidal superballs, and thus the phase behavior of such systems can be investigated experimentally.

description: Many drugs, especially when given in rapid sequence can cause histamine release. Ten healthy volunteers were premedicated with diazepam 10 mg.70 kg-1 i.v. and lormetazepam 1 mg.70 kg-1 i.v., respectively, 30 min prior to etomidate 0.15 mg.kg-1 i.v. in a single-blind, crossover study. The benzodiazepine lormetazepam and the hypnotic etomidate caused distinct increases in histamine plasma levels in two subjects. Maximal histamine levels after lormetazepam were 2.05 and 2.7 ng.ml-1, and after etomidate 1.85 and 3.2 ng.ml-1, respectively. Both drugs are solved in propylene glycol, a solvent that conveys very high osmolality (lormetazepam 6,750 mosm.kg-1, etomidate 4,900 mosm.kg-1). Clinical symptoms, like tachycardia, hypotension or allergic reactions, associated with similar histamine levels were not seen in either case. This limited histamine release appears to be caused by osmotic damage of tissue and blood cells.

description: Probing the evolution of physical systems at the femto- or attosecond timescale with light requires accurate characterization of ultrashort optical pulses. The time profiles of such pulses are usually retrieved by methods utilizing optical nonlinearities, which require significant signal powers and operate in a limited spectral range\cite{Trebino_Review_of_Scientific_Instruments97,Walmsley_Review_09}. We present a linear self-referencing characterization technique based on time domain localization of the pulse spectral components, operated in the single-photon regime. Accurate timing of the spectral slices is achieved with standard single photon detectors, rendering the technique applicable in any spectral range from near infrared to deep UV. Using detection electronics with about $70$ ps response, we retrieve the temporal profile of a picowatt pulse train with $\sim10$ fs resolution, setting a new scale of sensitivity in ultrashort pulse characterization.

An assessment of humanitarian intervention based on case studies by thematic analysis of debates on Libya and Syria in the British House of Commons, 2010-2014
Creators: name: Lewis, Aran Mark
Publisher: name: London South Bank University
Year: 2021

description: The objective of this thesis was to address the problem of the contradiction between the putative aims of humanitarian intervention and the harmful outcomes seen in intervention sites such as Libya (Hobson, 2016, Sensini, 2016, Cunliffe, 2020). The thesis contributes to knowledge by providing empirical evidence and contextual analysis of serious flaws in the contemporary theory and practise of humanitarian intervention, including the responsibility to protect (R2P) doctrine (International Commission on Intervention and State Sovereignty, 2001). Case studies of parliamentary debates on Libya and Syria from 2010 to 2014 permitted examination of arguments around intervention in the context of political debate and reported outcomes of intervention or non-intervention. From 2011, the British government supported coerced regime change in both countries on humanitarian grounds, but adopted different strategies in each case.1 Analysis of differences between British responses to Libya and Syria provided evidence of limited humanitarian motivation for intervention.2 Thematic analysis (Boyatzis, 1998) was chosen as a pragmatic method (Morgan, 2014) for identifying themes in the debates, assessing their relative predominance, tracking them over time, and analysing them in context. The case studies identified weaknesses in the R2P doctrine which suggest that it may be inherently counter-productive (Cunliffe, 2020), possibly due to problematisation of how to do more, rather than better, humanitarian intervention. The evidence indicates that the USA, France and Britain, the states most likely to be tasked with humanitarian military intervention, particularly under the R2P doctrine (Cunliffe, 2020), are not suitable for the role (Dunford and Neu, 2019a). This thesis did not identify a suitable and capable R2P intervention force. However, the evidence was insufficient to support a conclusion that R2P is defunct. The military intervention in Libya in 2011 was initially praised as an exemplar of the R2P in practise (Evans, 2011, Ban, 2012). Paradoxically, with the lessons of Western dissimulation and inhumane outcomes that emerged in Libya, and are evidenced in this thesis, informing Security Council decisions (United Nations Security Council, 2011a), R2P as amended by the General Assembly (United Nations General Assembly, 2005) may survive as a restraint against abusive humanitarian intervention.

description: We investigate magnetization reversal in a system of two Stoner particles with uniaxial anisotropies both subject to a static and antiparallel magnetic field, and taking into account their mutual dipolar interaction. We identify an interesting regime of stable synchronized magnetic dynamics where the two particles are implementing a single information bit. Here a modified Stoner-Wohlfarth limit occurs which results in a dramatically lower critical switching field Hc (including Hc = 0) and also a substantially shorter reversal time. Our analytical results are verified by numerical simulations and offer new technological perspectives regarding devices for information storage and/or fast magnetic response.
Neurobiological and behavioural effects of chronic administration of the D₂/₃ agonist ropinirole in relation to iatrogenic gambling disorder
Creators: name: Tremblay, Mélanie
Publisher: name: University of British Columbia
Year: 2017

description: Neurobiological changes in Parkinson’s Disease (PD) involve dramatic loss of dopamine neurons in the substantia nigra (SNc) and terminals in the dorsal striatum. L-DOPA, first line treatment for PD, can produce debilitating side-effects like dyskinesia over time. Preferential dopamine D2/3 agonists like ropinirole, are used to treat PD, but these newer drugs can lead to impulse control disorders (ICDs) and gambling disorder in a significant minority of patients. The mechanism mitigating dopamine replacement therapy (DRT)-induced ICDs, or whether premorbid behavioural tendencies are a risk factor are unknown. We show that chronic ropinirole increases preference for uncertainty on the rodent Betting task (rBT), regardless of animals’ baseline preference for the safe or uncertain option. Comparatively, ropinirole had subtle effects on choice of a cued version of the rat Gambling task (rGT), while increasing impulsivity, suggesting different neural mechanisms in performance of these tasks. GSK3ß has been involved in disorders of impulsivity suggesting a potential intracellular mechanism for DRT-ICDs. However, chronic administration of SB 216763, a GSK3ß inhibitor, did not attenuate gambling-like behaviours following ropinirole, but also did not reliably decrease GSK3ß levels, such that we were unable to unequivocally determine its role in ropinirole-induced preference for uncertainty. The “overdose” hypothesis, in which DRTs would replenish dopamine stores in the deteriorated dorsal striatum and improve movement, but overwhelm the mostly spared mesolimbic reward system, was suggested to explain DRT-ICDs in PD. However, newer studies suggest a potential involvement for the nigrostriatal, rather than mesolimbic, pathway in gambling disorders. We therefore manipulated the nigrostriatal pathway using designer receptors exclusively activated by designer drugs (DREADDs). Activation of dopamine neurons in the SNc increased preference for uncertainty on the rBT in wager-sensitive rats, partially mimicking the effect of ropinirole, while inhibition of these neurons had no effect on the increase in preference for uncertainty caused by ropinirole. These studies suggest a potential role for activation of the nigrostriatal pathway in DRT-ICDs. They also suggest that ICDs result from DRT alone, rather than from an interaction between medication and basal risk preference, or change in dopamine function caused by the diseases for which they are prescribed.

description: We apply the supernova(SN) extinction curves to reproduce the observed properties of SST J1604+4304 which is a young infrared (IR) galaxy at z = 1. The SN extinction curves used in this work were obtained from models of unmixed ejecta of type II supernovae(SNe II) for the Salpeter initial mass function (IMF) with a mass range from 8 to 30 M_sun or 8 to 40 M_sun. The effect of dust distributions on the attenuation of starlight is investigated by performing the chi-square fitting method against various dust distributions. These are the commonly used uniform dust screen, the clumpy dust screen, and the internal dust geometry. We add to these geometries three scattering properties, namely, no-scattering, isotropic scattering, and forward-only scattering. Judging from the chi-square values, we find that the uniform screen models with any scattering property provide good approximations to the real dust geometry. Internal dust is inefficient to attenuate starlight and thus cannot be the dominant source of the extinction. We show that the SN extinction curves reproduce the data of SST J1604+4304 comparable to or better than the Calzetti extinction curve. The Milky Way extinction curve is not in satisfactory agreement with the data unless several dusty clumps are in the line of sight. This trend may be explained by the abundance of SN-origin dust in these galaxies; SN dust is the most abundant in the young IR galaxy at z = 1, abundant in local starbursts, and less abundant in the Galaxy. If dust in SST J1604+4304 is dominated by SN dust, the dust production rate is about 0.1 M_sun per SN.

description: We report here on a local spin valve effect observed unambiguously in lateral all-semiconductor all-electrical spin injection devices, employing p+ −(Ga,Mn)As/n+ −GaAs Esaki diode structures as spin aligning contacts. We discuss the observed local spin-valve signal as a result of the interplay between spin-transport-related contribution and the tunneling anisotropic magnetoresistance of the magnetic contacts. The magnitude of the spin-related magnetoresistance change is equal to 30 Ω which is twice the magnitude of the measured non-local signal.

description: The deuteroporphyrin-IX derivative Dimegin [2,4-di-(α-methoxyethyl)-deuteroporphyrin IX] was investigated with respect to cellular uptake, intracellular localization and cell survival following photodynamic treatment in human cell lines derived from the skin (SCL1 and SCL2, squamous cell carcinoma; HaCaT keratinocytes; N1 fibroblasts). Using flow cytometry, we determined the cellular fluorescence as a marker of the uptake of Dimegin after incubation for 24 h. The intracellular localization of Dimegin was analysed using fluorescence microscopy and co-staining with fluorescent dyes specific for cell organelles. Following irradiation with an incoherent light source (580–740 nm) using a light dose of 24 J/cm2, phototoxicity was determined by means of trypan blue dye exclusion, MTT assays and growth curves. The relative Dimegin fluorescence of the different cell lines declined as follows: SCL1>HaCat>N1>SCL2. Intracellular localization of Dimegin was found in the mitochondria. For all cell lines Dimegin concentrations above 15 mM yielded a significant phototoxic effect. The EC50 for SCL1 cells was 8.9±2.0 μM Dimegin. The EC50 for the cell lines increased as follows: SCL1

description: This paper addresses fundamental aspects of statistical mechanics such as the motivation of a classical state space with spontaneous transitions, the meaning of non-equilibrium in the context of thermalization, and the justification of these concepts from the quantum-mechanical point of view. After an introductory part we focus on the problem of entropy production in non-equilibrium systems. In particular, the generally accepted formula for entropy production in the environment is analyzed from a critical perspective. It is shown that this formula is only valid in the limit of separated time scales of the system's and the environmental degrees of freedom. Finally, we present an alternative simple proof of the fluctuation theorem.

The predicted nonlinear parameters strongly depend on the size of a curvaton self-coupling constant as well as the reheating temperature after inflation for a given initial amplitude of the curvaton. The difference from usual massive self-interacting curvaton is also emphasized.

Empowerment power : NGOs and feminisms in Dar es Salaam
Creators: name: Allan, Emily
Publisher: name: University of British Columbia
Year: 2017

description: In this thesis, I examine circulating discourses of “women’s empowerment” in Dar es Salaam, one of Africa’s urban epicentres of NGOization. Through the ethnographic fieldwork that I conducted in Dar es Salaam’s NGO sphere from May to August of 2016, I illustrate why development critique and intersectional feminisms must emphasize agency and variation, and avoid falling into binaries and Eurocentrism. Based on participant observation in “local” and “expat” circles, and formal interviews with Tanzanian NGO workers, I address the following questions: how does development discourse in Tanzania use tropes of women’s empowerment? Whom do these discourses serve? In what ways do participants’ comments on development speak to their geopolitical locations, race, class and gendered positionalities? I argue that “empowerment” language is easily co-opted to obscure structural inequalities among international and local agents, as well as the state and its citizenry. I caution against simplistic and prescriptive applications of critiques of “Western” development activities and white liberal feminism in an analysis of how empowerment discourse too often produces narrow images of power, recognizing that empowerment discourses are strategically activated within differing contexts and must be examined in their particularities.
The significance of individual contributions to the history of Kildonan UnitingCare.
Creators: name: Lane, Sharron
Publisher: name: Ausatralian Catholic University
Year: 2018

description: This thesis explores the history of the Victorian community service organisation which until June 2017 was known as Kildonan UnitingCare, and its historical predecessors, through the prisms of leadership and change. The Neglected and Criminal Children’s Act 1864 established a child welfare system where both the government and private establishments could take charge of children. Successive governments did not merely tolerate these private providers but actively partnered with them, and over the course of two decades this entrenched a decentralised system. The thesis argues that this created an environment where individuals within private organisations could develop new methods of care and use their organisations as a platform to change the nature of the sector more broadly. Kildonan, established in 1881, provides three examples of such significant contributions. Selina Murray MacDonald Sutherland founded the work as a lady missionary at the Scots’ Church in Melbourne, and achieved a position of such prominence that she was able to persuade government to legitimate the work of private child rescuers through legislation, a recognition that was sought but rarely achieved by child rescue advocates in other parts of the world. In the 1950s two more leaders emerged, transforming not only Kildonan but also leading changes across the sector as a whole. Alison Player brought insights from her training as a social worker to lead the planning process that moved the organisation away from a focus on institutional care in the 1950s. She was followed by Alfred Spencer Colliver who, as Superintendent from 1957, developed the scattered family group home system, and worked alongside government to persuade other child care organisations to follow a similar path. By comparing a range of sources to reconstruct what has been a poorly documented field this thesis shows how individuals, and the informal relationships they were able to develop with others in the sector, were crucial to the ongoing development of child welfare policy across Victoria’s decentralised array of support services.

description: We report on the optical properties of m-plane GaInN/GaN quantum wells (QWs). We found that the emission energy of GaInN QWs grown on m-plane SiC is significantly lower than on non-polar bulk GaN, which we attribute to the high density of stacking faults. Temperature and power dependent photoluminescence reveals that the GaInN QWs on SiC have almost as large internal quantum efficiencies as on bulk GaN despite the much higher defect density. Our results indicate that quantum-wire-like features formed by stacking faults intersecting the quantum wells provide a highly efficient light emission completely dominating the optical properties of the structures.

description: In the solar photosphere, many properties of coronal holes (CHs) are not known, especially vector magnetic fields. Using observations from \emph{Hinode}, we investigate vector magnetic fields, current densities and current helicities in two CHs and compare them with two normal quiet regions (QRs) for the first time. We find that, in the CHs and QRs, the areas where large current helicities are located are mainly co-spatial with strong vertical and horizontal field elements both in shape and location. In the CHs, horizontal magnetic fields, inclination angles, current densities and current helicities are larger than those in the QRs. The mean vertical current density and current helicity, averaged over all the observed areas including the CHs and QRs, are approximately 0.008 A m$^{-2}$ and 0.005 G$^{2}$ m$^{-1}$, respectively. The mean current density in magnetic flux concentrations where the vertical fields are stronger than 100 G is as large as 0.012 $\pm$ 0.001 A m$^{-2}$, consistent with that in the flare productive active regions. Our results imply that the magnetic fields, especially the strong fields, both in the CHs and QRs are nonpotential.

description: Sugar binding proteins of the thermoacidophile Sulfolobus solfataricus function together with ABC transporters in the uptake of sugars. They are synthesized as precursors with a class III signal peptide that are normally found in archaeal flagellins and bacterial type IV pilins. The functional expression of sugar binding proteins at the cell surface is dependent on the bindosome assembly system (Bas) that is homologous to bacterial type IV pilin assembly systems. The Bas system consists of an assembly ATPase, BasE; a membrane anchoring protein, BasF; and three small class III signal peptide containing proteins BasABC. Expression of BasEF in a S. solfataricus DbasEF strain restored the uptake of glucose, while an ATPase mutant of BasE was unable to complement. BasEF was detergent-extracted from S. solfataricus membranes as a stable protein complex. Solute binding proteins can be extracted from the cell surface as two high molecular mass complexes of 600 and 400 kDa, wherein the largest complex also contains the main S-layer protein SlaA. Electron microscopic analysis of the cell surface of the wild-type and DbasEF strain indicates that the absence of the BasEF complex causes an alteration in cell morphology and the corrugation of the S-layer pattern that is reversed by complementation with the BasEF complex. These results suggest an interaction between the S-layer and the sugar binding proteins that contribute to cell shape.

description: As massive stars evolve, their winds change. This causes a series of hydrodynamical interactions in the surrounding medium. Whenever a fast wind follows a slow wind phase, the fast wind sweeps up the slow wind in a shell, which can be observed as a circumstellar nebula. One of the most striking examples of such an interaction is when a massive star changes from a red supergiant into a Wolf-Rayet star. Nebulae resulting from such a transition have been observed around many Wolf-Rayet stars and show detailed, complicated structures owing to local instabilities in the swept-up shells. Shells also form in the case of massive binary stars, where the winds of two stars collide with one another. Along the collision front gas piles up, forming a shell that rotates along with the orbital motion of the binary stars. In this case the shell follows the surface along which the ram pressure of the two colliding winds is in balance. Using the MPI-AMRVAC hydrodynamics code we have made multi-dimensional simulations of these interactions in order to model the formation and evolution of these circumstellar nebulae and explore whether full 3D simulations are necessary to obtain accurate models of such nebulae.

description: Dialogue games are two-player logic games between a Proponent who puts forward a logical formula A as valid or true and an Opponent who disputes this. An advantage of the dialogical approach is that it is a uniform framework from which different logics can be obtained through only small variations of the basic rules. We introduce the composition problem for dialogue games as the problem of resolving, for a set S of rules for dialogue games, whether the set of S-dialogically valid formulas is closed under modus ponens. Solving the composition problem is fundamental for the dialogical approach to logic; despite its simplicity, it often requires an indirect solution with the help of significant logical machinery such as cut-elimination. We give a set N of dialogue rules that is quite close to a set of rules known to characterize classical propositional logic, and which is evidently well-justified from the dialogical point of view, but whose set of dialogically valid formulas is quite peculiar (and non-trivial). Its peculiarity notwithstanding, the composition problem for N can be solved directly.

description: Anthralin 1 and some of its C-10 or O-alkylated derivatives were investigated by UV/VIS- and fluorescence spectroscopy in different solvents and buffer systems, respectively. The effects of substituents on the formation of anthralin anion as well as the constitution of the resulting anions confirm that C-H acidity at position 10 is necessary for the formation of a fully aromatic anionic form. It is concluded that the resulting anion 1a is the pharmacologically active species of the antipsoriatic anthralin. Tautomerism of the neutral molecule is not observable.
Multistable attractors in a network of phase oscillators with three-body interaction

description: Three-body interactions have been found in physics, biology, and sociology. To investigate their effect on dynamical systems, as a first step, we study numerically and theoretically a system of phase oscillators with three-body interaction. As a result, an infinite number of multistable synchronized states appear above a critical coupling strength, while a stable incoherent state always exists for any coupling strength. Owing to the infinite multistability, the degree of synchrony in asymptotic state can vary continuously within some range depending on the initial phase pattern.

description: The scale invariant of the effective potential of the standard model at two-loop is used as a boundary condition under the assumption that the two-loop effective potential approximates the full effective potential. This condition leads with the help of the renormalization group functions of the model at two-loop to an algebraic equation of the scalar self coupling with coefficients that depend on the gauge and the top quark couplings. It admits only two real positive solutions. One of them, in the absence of the gauge and top quark couplings, corresponds to the non-perturbative ultraviolet fixed point of the scalar renormalization group function and the other corresponds to the perturbative infrared fixed point. The dependence of the scalar coupling on the top quark and the strong couplings at two-loop radiative corrections is analyzed.

Longwave luminescent porphyrin probes

description: A set of luminescent dyes, namely the porphyrin-ketones and their zinc(II), platinum(II) and palladium(II) complexes, are described. The probes are derived from a partially oxidized porphyrin ring and have been studied by absorption and luminescence spectroscopy including time-resolved measurements. The metal-free porphyrin-ketones display strong and pH-dependent fluorescence due to a protolytic equilibrium that exists between the free base and the dication. The zinc(II) complexes also give strong fluorescence along with a weak long-decay emission at room temperature which are attributed to delayed fluorescence and phosphorescence, respectively. Platinum(II) and palladium(II) complexes exhibit room-temperature phosphorescence without any detectable fluorescence. Compared to existing porphyrins, the new dyes display a considerably longwave-shifted luminescence along with substantially improved (photo)chemical stability. They are considered to be promising probes for very near-infrared luminescence studies, and to be particularly useful for applications such as labelling of biomolecules, pH-sensing, and detection of quenching species such as molecular oxygen.

description: Nanoarchaeum equitans und Ignicoccus hospitalis sind anaerobe hyperthermophile Mikroorganismen. Sie repräsentieren eine einzigartige, rein archaeelle Lebensgemeinschaft, in der N. equitans zwingend auf seinen Wirt I. hospitalis angewiesen ist, da es alle seine Lipide und Aminosäuren von ihm bezieht. I. hospitalis lebt von der Reduktion elementaren Schwefels mit Wasserstoff. Er besitzt einen neuen CO2-Fixierungsweg und eine für Archaeen einmalige Zellstruktur aus innerer und äußerer Membran, die zwei Zellkompartimente bilden, das Cytoplasma und einen großen Intermembranraum. Durch immunologische Analysen zeigten wir, dass bei I. hospitalis die ATP-Synthase- und die H2:Schwefel-Oxidoreduktase-Komplexe in seiner äußeren Membran lokalisiert sind. Damit ist er der erste Prokaryot mit einer energetisierten äußeren Membran, ATP-Synthese außerhalb des Cytoplasmas und der räumlichen Trennung von Energiekonservierung und Informationsübertragung oder Proteinbiosynthese. Daraus ergeben sich zahlreiche Fragen zur Funktion und Charakterisierung der beiden Membranen und Zellkompartimente sowie einem möglichen Energietransfer zu N. equitans. An enigmatical association of two Archaea The obligate anaerobic hyperthermophilic Nanoarchaeum equitans and Ignicoccus hospitalis represent a unique, purely archaeal biocoenosis which is mandatory for N. equitans. Its strong dependence on I. hospitalis is affirmed by the fact that its lipids and amino acids are obtained exclusively from the host. The Crenarchaeon I. hospitalis is characterized by energy production via reduction of elemental sulfur with molecular hydrogen and a novel CO2-fixation pathway. It possesses a unique cell envelope for Archaea with an inner and an outer membrane, forming two cell compartments, the cytoplasm and a huge intermembrane compartment. By immuno-analyses we demonstrated that the ATP synthase and H2:sulfur oxidoreductase complexes of I. hospitalis are located in the outer membrane. Thus I. hospitalis is the first Prokaryote with an energized outer membrane, ATP synthesis outside the cytoplasm, and spatial separation of energy conservation from information processing and protein biosynthesis. This raises many questions on the function and characterization of the two membranes, the two cell compartments, and a possible ATP transfer to N. equitans.
