description: During de Sitter inflation massless particles of minimally coupled scalar fields acquire a mass and a decay width thereby becoming \emph{quasiparticles}. For bare massless particles non-perturbative infrared radiative corrections lead to a self-consistent generation of mass, for a quartic self interaction $M \propto λ^{1/4} H$, and for a cubic self-interaction the mass is induced by the formation of a non-perturbative \emph{condensate} leading to $M \propto λ^{1/3} H^{2/3}$. These radiatively generated masses restore de Sitter invariance and result in anomalous scaling dimensions of superhorizon fluctuations. We introduce a generalization of the non-perturbative Wigner-Weisskopf method to obtain the time evolution of quantum states that include the self-consistent generation of mass and regulate the infrared behavior. The infrared divergences are manifest as poles in $Δ=M^2/3H^2$ in the single particle self-energies, leading to a re-arrangement of the perturbative series non-analytic in the couplings. A set of simple rules that yield the leading order infrared contributions to the decay width are obtained and implemented. The lack of kinematic thresholds entail that all particle states acquire a decay width, dominated by the emission and absorption of superhorizon quanta $\propto (λ/H)^{4/3}\,[H/k_{ph}(η)]^6 ; λ\,[H/k_{ph}(η)]^6 $ for cubic and quartic couplings respectively to leading order in $M/H$. The decay of single particle quantum states hastens as their wavevectors cross the Hubble radius and their width is related to the highly squeezed limit of the bi- or tri-spectrum of scalar fluctuations respectively.

description: On average, mothers and fathers in Germany divide paid work and care work very unequally. Mothers often only work part time, which results in further gender inequalities in the labor market. A current analysis of data from the German Family Demography Panel Study (FReDA) shows that the population’s attitudes toward the ideal division of work between couples with children under 12 are considerably more egalitarian than the actual behavior of couples with young children of different ages. This discrepancy is due in part to the financial incentives of the German tax and transfer system for married couples, which arise from the interplay between income splitting (Ehegattensplitting) and the tax treatment of mini-jobs. In addition, childcare infrastructure is insufficient and a very high gender pay gap persists in Germany. If policymakers want to dismantle inequalities in the labor market, the tax and transfer system must be modernized and childcare options expanded to make a more equal division of paid work and care work between parents more appealing.

description: Greenhouse gas emissions must be reduced by 65 percent compared to 1990 by 2030 to achieve national climate targets. Nearly one third of greenhouse gas emissions in Germany are caused by private household consumption. Using Socio-Economic Panel (SOEP) data, this Weekly Report calculates the amount of CO2 equivalents emitted by households due to residential energy use, nutrition, and transport in Germany. Consumption in these three areas alone results in average emissions that exceed the emissions budget targeted for private individuals more than twofold, with transport and residential energy-related emissions accounting for the largest share of emissions. Emissions increase as income increases, especially in the area of transport, with air travel as the main driver. Meat consumption is the main contributor to nutrition-related emissions, and household size and building type contribute the most to residential energy-related emissions. By identifying the most significant driver of emissions in each of the three areas, targeted political instruments can be identified, such as simplifying housing swaps and the energy-efficient renovation of residential buildings, banning short-haul flights, and introducing an animal welfare levy.

Nsyilxcen modality : semantic analysis of epistemic modality
Creators: name: Menzies, Stacey
Publisher: name: University of British Columbia
Year: 2013

description: The aim of this thesis is to describe and analyze the modal system of Nsyilxcen, an Interior Salish language spoken in south central British Columbia and northern Washington State. In particular, it focuses on the epistemic modals mat and cmay, which express necessity and possibility with respect to certain bodies of knowledge. Similar to modals in St'át'imcets (Rullmann et al. 2008) and Gitksan (Peterson 2010) these modals lexically encode an epistemic modal base and an indirect inferential evidential restriction. I propose that these two modals can be distinguished based on their modal force distinction, where mat has variable modal force and cmay a strictly encoded existential modal force. Based on these generalizations, I propose a formal semantic analysis for the epistemic modals drawing from Kratzer (1977, 1981, 1991, 2012), Rullmann et al. (2008), Peterson (2010), and Deal (2011). The analysis defines each modal in a way that accounts for the strictly encoded modal base and evidential restriction, as well as the variable modal force for mat and the strictly encoded existential modal force for cmay. In addition to the epistemic modals mat and cmay this thesis documents the reportative modal kʷukʷ as well as how Nsyilxcen encodes non-epistemic modality. It looks at the bouletic modal cakʷ and how Nsyilxcen encodes a deontic, circumstantial, ability, and teleological modal base which makes use of the irrealis marker ks-, imperative markers -x and -ikʷ, or the basic predicate, depending on the addressee and the context. This thesis will discuss how the Nsyilxcen system fits into a preliminary modal typology based on the semantics of these modals.

Un modello di decisione per l'eugenetica: il criterio del maximin
Creators: name: Colombo, Camilla
Publisher: name: Rivista Italiana di Filosofia Analitica Junior
Year: 2012

description: In un ipotetico scenario tecnologicamente molto più avanzato di quello attuale, in cui sia possibile modificare alcune caratteristiche di un feto attraverso interventi di ingegneria genetica, viene illustrato un possibile problema etico circa la legittimità di tali interventi. In particolare, nell’esempio trattato ci si chiede quando e se sia legittimo per un genitore autorizzare un intervento genetico su suo figlio. Il casus fictus è analizzato utilizzando gli strumenti della Teoria della Decisione Razionale (TDR), costruendo un opportuno modello di decisione che consenta di rispettare un vincolo di razionalità e un vincolo di giustizia. Il modello proposto si caratterizza come alternativo rispetto a quelli classici della TDR, poiché il problema in analisi non può essere risolto in una matrice di decisione individuale, che non tiene conto della componente interpersonale di una scelta riguardante l’eugenetica, né come un caso di Scelta Sociale, perché le preferenze di uno degli individui coinvolti sono indefinite al momento della decisione. La soluzione prospettata è l’utilizzo del criterio di decisione del maximin, formalizzato da Von Neumann e Morgenstern, in luogo della massimizzazione dell’utilità prevista. Tale criterio, attraverso astrazioni (sul problema) e idealizzazioni (sull’agente) consente di rispettare i due vincoli di razionalità e giustizia, imponendo al genitore di autorizzare solo quegli interventi genetici che non diminuiscano il successo del nascituro in un piano di vita possibile. Questo criterio di decisione, a differenza dei criteri di demarcazione tra terapia e avanzamento utilizzati frequentemente in letteratura, è solo procedurale, ma non vuoto perché risponde a istanze di giustizia. Inoltre, il problema dell’autorizzazione degli interventi genetici rappresenta un caso di applicazione giustificata di un criterio di decisione generalmente non ritenuto ragionevole, perché troppo conservativo e prudente. Il caso dell’eugenetica si caratterizza quindi come un esempio intuitivo e immediato di una classe di problemi di scelta intepersonale, per i quali viene proposto che il criterio di decisione razionale sia la massimizzazione dell’utilità nel peggior caso possibile, cioè il criterio del maximin.

description: We investigate two-party cryptographic protocols that are secure under assumptions motivated by physics, namely relativistic assumptions (no-signalling) and quantum mechanics. In particular, we discuss the security of bit commitment in so-called split models, i.e. models in which at least some of the parties are not allowed to communicate during certain phases of the protocol. We find the minimal splits that are necessary to evade the Mayers-Lo-Chau no-go argument and present protocols that achieve security in these split models. Furthermore, we introduce the notion of local versus global command, a subtle issue that arises when the split committer is required to delegate non-communicating agents to open the commitment. We argue that classical protocols are insecure under global command in the split model we consider. On the other hand, we provide a rigorous security proof in the global command model for Kent's quantum protocol [Kent 2011, Unconditionally Secure Bit Commitment by Transmitting Measurement Outcomes]. The proof employs two fundamental principles of modern physics, the no-signalling property of relativity and the uncertainty principle of quantum mechanics.

"Mentire è moralmente sbagliato" è una tautologia? Una risposta a Margolis
Creators: name: Marsili, Neri
Publisher: name: Rivista Italiana di Filosofia Analitica Junior
Year: 2012

description: All’interno del dibattito sulla definizione filosofica della menzogna,
alcuni autori hanno sostenuto che mentire è sempre sbagliato. Margolis, in particolare, ha espresso la tesi radicale secondo cui “mentire è moralmente sbagliato” è una tautologia. Nella prima parte dell’articolo introduco la tesi di Margolis, e ne difendo la plausibilità contro le semplificazioni che ha subito all’interno del dibattito filosofico, mostrando che l’applicazione condizionale del predicato “sbagliato” consente di trattare in modo adeguato alcune menzogne intuitivamente giustificabili. Nella seconda parte argomento che, nonostante questo stratagemma, non è possibile difendere la tesi che “mentire è moralmente sbagliato” sia una tautologia, perché bisognerebbe assumere che “mentire è moralmente sbagliato” sia una condizione necessaria fra quelle che definiscono il concetto stesso di menzogna.
Questo non è desiderabile perché, come dimostro nella parte finale del mio articolo, ogni definizione di menzogna che incorpori requisiti morali nelle sue condizioni necessarie é destinata a contraddire le intuizioni del senso comune su che cos’é una menzogna. La conclusione è che la tesi che “mentire è moralmente è sbagliato” è una tautologia non può essere difesa, se non al prezzo, troppo alto, di ridefinire in modo controintuitivo il significato del termine “menzogna”.

The concept of deference in substantive review of administrative decisions in four common law countries
Creators: name: Freckelton, Alan
Publisher: name: University of British Columbia
Year: 2013

description: This thesis examines the concept of “deference” in relation to judicial review of administrative decisions in Canada, and then compares this approach to judicial review to that which exists in the United Kingdom, New Zealand and Australia. Canadian courts have adopted a system of “substantive review” of administrative decisions, at least since 1979 (if not earlier), and will generally show deference to the decision-maker. It is important to note that Canadian courts have interpreted the word “deference” not as subservience (an approach that would make judicial review pointless), but as a form of “respectful attention” to the decision under review. Canadian courts recognise that they do not have a monopoly of wisdom on matters of statutory interpretation, but will step in to set a decision aside when that decision is unreasonable in some sense. Courts in the United Kingdom have recognised at least since 1987 that the classic standard of Wednesbury unreasonableness – that the decision is “so unreasonable that no reasonable person could have made it” – is not suitable for all kinds of administrative decisions, and have moved to a system whereby there is a “variegated standard” of reasonableness on judicial review for matters not covered by the Human Rights Act 1998, and a proportionality approach for those that are. The law in New Zealand is not as clear, because the Supreme Court has yet to squarely approach the issue, but the lower courts certainly appear to be moving in a similar direction. However, Australian courts vehemently deny that they show any deference to administrative decision-makers, and Australian academic commentators are equally insistent that such an approach is legally suspect at best and mere obsequiousness to government at worst. This is despite the fact that Australia has always recognised Wednesbury unreasonableness as a ground of judicial review. This thesis attempts to dispel some of the Australian arguments against a deference approach, particularly in relation to s.75 of the Australian Constitution, and concludes that Australia would be best off adopting a form of substantive review of administrative decisions, similar to that which exists in Canada.

description: We study a model of competition for resource through a chemostat-type model where species consume the common resource that is constantly supplied. We assume that the species and resources are characterized by a continuous trait. As already proved, this model, although more complicated than the usual Lotka-Volterra direct competition model, describes competitive interactions leading to concentrated distributions of species in continuous trait space. Here we assume a very fast dynamics for the supply of the resource and a fast dynamics for death and uptake rates. In this regime we show that factors that are independent of the resource competition become as important as the competition efficiency and that the direct competition model is a good approximation of the chemostat. Assuming these two timescales allows us to establish a mathematically rigorous proof showing that our resource-competition model with continuous traits converges to a direct competition model. We also show that the two timescales assumption is required to mathematically justify the corresponding classic result on a model consisting of only finite number of species and resources (MacArthur, R. Theor. Popul. Biol. 1970:1, 1-11). This is performed through asymptotic analysis, introducing different scales for the resource renewal rate and the uptake rate. The mathematical difficulty relies in a possible initial layer for the resource dynamics. The chemostat model comes with a global convex Lyapunov functional. We show that the particular form of the competition kernel derived from the uptake kernel, satisfies a positivity property which is known to be necessary for the direct competition model to enjoy the related Lyapunov functional.

description: This essay was prepared as part of the Economics for Inclusive Prosperity (EfIP) series of policy briefs. Anat Admati is from the Graduate School of Business, Stanford University. I am grateful to Dani Rodrik and Graham Steele for helpful comments. The financial system is fragile and distorted because current rules fail to counter the distorted incentives by banking institutions to borrow excessively and to remain opaque. Better-designed rules to reduce the reliance on debt and ensure that institutions use significantly more equity would enable the financial system to serve society better. Revising counterproductive tax and bankruptcy codes that, together with the extensive safety net offered to the financial system currently encourage dangerous conduct, would also be beneficial.

description: Several mechanisms by which an external electromagnetic field influences the temperature of a plasma are studied analytically and specialized to the system of an ultracold plasma (UCP) driven by a uniform radio frequency (RF) field. Heating through collisional absorption is reviewed and applied to UCPs. Furthermore, it is shown that the RF field modifies the three body recombination process by ionizing electrons from intermediate high-lying Rydberg states and upshifting the continuum threshold, resulting in a suppression of three body recombination. Heating through collisionless absorption associated with the finite plasma size is calculated in detail, revealing a temperature threshold below which collisionless absorption is ineffective.

description: Web applications require exchanging parameters between a client and a server to function properly. In real-world systems such as online banking transfer, traversing multiple pages with parameters contributed by both the user and server is a must, and hence the applications have to enforce workflow and parameter dependency controls across multiple requests. An application that applies insufficient server-side input validations is however vulnerable to parameter tampering attacks, which manipulate the exchanged parameters. Existing fuzzing-based scanning approaches however neglected these important controls, and this caused their fuzzing requests to be dropped before they can reach any vulnerable code. In this paper, we propose a novel approach to identify the workflow and parameter dependent constraints, which are then maintained and leveraged for automatic detection of server acceptances during fuzzing. We realized the approach by building a generic blackbox parameter tampering scanner. It successfully uncovered a number of severe vulnerabilities, including one from the largest multi-national banking website, which other scanners miss.

description: Merger control plays a central role in competition policy. When assessing proposed mergers, Competition Authorities should consider its impact on all relevant markets. Large mergers between manufacturers typically impact competition, thus requiring the approval of Competition Authorities. Divestitures are often a condition of merger approval. This report investigates the effectiveness of implementing such merger remedies when bargaining between manufacturers and retailers is a key market feature. We examine the upstream merger between DEMB and Mondeléz that was approved by the European Commission in May 2015, subject to a divestiture. The divestiture indeed helped to mitigate the negative impacts of the merger. From the consumer’s point of view, divestitures should take place in favor of manufacturers with less bargaining power.

description: We calculate the relic abundance of mixed axion/neutralino cold dark matter which arises in R-parity conserving supersymmetric (SUSY) models wherein the strong CP problem is solved by the Peccei-Quinn (PQ) mechanism with a concommitant axion/saxion/axino supermultiplet. By numerically solving the coupled Boltzmann equations, we include the combined effects of 1. thermal axino production with cascade decays to a neutralino LSP, 2. thermal saxion production and production via coherent oscillations along with cascade decays and entropy injection, 3. thermal neutralino production and re-annihilation after both axino and saxion decays, 4. gravitino production and decay and 5. axion production both thermally and via oscillations. For SUSY models with too high a standard neutralino thermal abundance, we find the combined effect of SUSY PQ particles is not enough to lower the neutralino abundance down to its measured value, while at the same time respecting bounds on late-decaying neutral particles from BBN. However, models with a standard neutralino underabundance can now be allowed with either neutralino or axion domination of dark matter, and furthermore, these models can allow the PQ breaking scale f_a to be pushed up into the 10^{14}-10^{15} GeV range, which is where it is typically expected to be in string theory models.

description: As a result of the Russian attack on Ukraine, natural gas prices skyrocketed in 2022 and Germany in particular felt the impact of its strong dependency on Russia. Prices have since relaxed, the European natural gas industry has overcome the uncertainty due to the energy crisis in 2022, and the industry also survived the slump in Russian natural gas imports without supply interruptions. However, Russia continues to export liquefied natural gas (LNG) to Europe and still has some countries in Central and Eastern Europe under control in terms of energy policy, which has so far prevented EU sanctions on Russian natural gas exports. Both the German and European natural gas supplies would be secure in the long term without Russian imports, as shown by model calculations using the Global Gas Model which depicts the global natural gas industry in great detail. Security of supply is, thus, not standing in the way of further EU sanctions against Russia. Increased efforts to save energy and a timely natural gas phase-out would reduce dependency on gas imports, which will also contribute to climate change mitigation.

description: The German electricity market has recovered well from the 2022 energy crisis. Policymakers should now redirect the focus of energy policy to further expanding renewable energy sources. The year 2023 showed that the German electricity supply remained secure following the shutdown of nuclear power plants. It is possible, affordable, and plausible in light of climate policy to cover 80 percent of electricity consumption with renewable energy sources, as the German Renewable Energy Sources Act plans for by 2030. However, a swift exit from coal, and natural gas in the long run, is required to achieve this, as is suggested by scenario analyses that track the price and volume effects as well as the grid situation on the German electricity market for the present and for 2030. The shutdown of nuclear power plants has been planned for a long time and was by no means a relevant driver of electricity prices. Rather, French nuclear power plants’ erratic downtimes as well as war-related increases in gas prices drove up electricity prices. The construction of new nuclear power plants, which has been discussed by policymakers, is irrelevant for the energy transformation over the next decades. The natural gas crisis has also ended. In addition to the coal phase-out, the fossil fuel phase-out is an integral part of the energy transformation.

description: German companies view high and uncertain electricity prices a major challenge. A Renewable Energy Pool (RE-Pool), wherein the favorable conditions of competitive tenders for new wind and solar power projects are passed on to electricity consumers, could hedge such price risks. Consumers’ electricity prices are thus hedged for the share of their consumption that corresponds to the RE-Pool’s generation profile. This, in turn, strengthens the incentives to invest in flexibility, such as in heat storage systems or batteries, in order to adjust their demand to wind and solar electricity production in the pool. In addition, the RE-Pool profile can serve as a reference against which new products to hedge flexibility can be introduced in the futures and forward markets. The RE-Pool also addresses financing risks linked to regulatory uncertainties faced by renewable energy projects. This reduces financing costs and thus costs for consumers and enhances confidence in future renewable deployment and thus supports investments into the supply chain of project developers and manufacturers. The RE-Pool contributes to an even better use of renewable energy sources in the energy supply and prepares the electricity system for a future powered by a greater share of renewable energy.

description: The analysis of recent, extended multicolour CCD and archive photoelectric, photographic and visual observations has revealed several important properties of RZ Lyr, an RRab-type variable exhibiting large-amplitude Blazhko modulation. On the time-base of \sim110 yr, a strict anticorrelation between the pulsation and modulation period changes is established. The light curve of RZ Lyr shows a remarkable bump on the descending branch in the small-amplitude phase of the modulation, similarly to the light curves of bump Cepheids. We speculate that the stellar structure temporally suits a 4:1 resonance between the periods of the fundamental and one of the higher-order radial modes in this modulation phase. The light-curve variation of RZ Lyr can be correctly fitted with a two-modulation-component solution; the 121 d period of the main modulation is nearly but not exactly four times longer than the period of the secondary modulation component. Using the inverse photometric method, the variations in the pulsation-averaged values of the physical parameters in different phases of both modulation components are determined.
