description: Traditionally, farms expand by buying out a neighbour. But might remote partnerships be a better way of expanding a farm business given projected climate change and price volatility? This question is addressed using farm business financial modelling. Representative farms at 27 locations in Western Australia are constructed to enable comparison of the value of buying out a neighbour versus expansion using geographically distant joint venture (JV) partners. The farm models consider economies of size, bulk purchase price discounts, the variability and correlation of returns associated with farm expansion, and impacts of climate change. Random selection of a remote partner generates little improvement in wealth; on average only 2.3 and 1.6 per cent, respectively, under current and projected future climate across all locations. However, there is large variation in wealth appreciation opportunities for each location and between locations. Preferred partnerships are a function of each farm’s characteristics. Locations highly preferred as JV partners under current climate are similarly preferred partners under projected future climate. The main sources of additional wealth come from economies of size advantages, risk-spreading benefits of combining geographically separated farms and bulk discounts. Farmers seeking business expansion will often benefit greatly from careful selection of a remote partner.
Evolution of the Chameleon Scalar Field in the Early Universe

description: In order to satisfy limits on the allowed variation of particle masses from big bang nucleosynthesis (BBN) until today, the chameleon scalar field is required to reach its attractor solution early on in its cosmological evolution. Brax et al. (2004) have shown this to be possible for certain specific initial conditions on the chameleon field at the end of inflation. However the extreme fine-tuning necessary to achieve this, poses a problem if the chameleon is to be viewed a natural candidate for dark energy. In this article we revisit the behaviour of the chameleon in the early Universe, including the additional coupling to electromagnetism proposed by Brax et al. (2011). Solving the chameleon evolution equations in the presence of a primordial magnetic field, we find that the strict initial conditions on the chameleon field at the end of inflation can be relaxed, and we determine the associated lower bound on the strength of the primordial magnetic field.

Patterns of new firm survival and growth in the italian financial intermediation industry

description: This paper studies the post-entry evolution of two cohorts of entrants in the Italian financial intermediation industry. Using a comprehensive longitudinal database, it analyses the link between duration and growth of each newborn firm and its start-up size, as well as a series of industry-specific characteristics. It emerges that not only did regulatory reform in 1990 result in a process of branch proliferation and industry consolidation, but it also set in motion a pre-entry selection mechanism and rendered life after entry for newborn firms more difficult. Conversely, before completion of the regulatory reform, in 1989, entry was possible even for very small firms, and larger new entrants were able to resist longer periods of bad performance than their smaller counterparts before being forced to exit the market, and this independently of the features of spatial and structural competition.

description: Reducing dependence on fossil fuels by decreasing energy consumption is a common environmental policy. One mechanism used to achieve this is to encourage increased energy efficiency. However, improving efficiency may have an opposing effect and cause an increase in energy consumption if the intensity of use changes. This phenomenon is known as the rebound effect. We estimate direct rebound effects for energy use in Australia based on both aggregate residential energy use data and on household energy expenditure data. Our approach implements a new methodology developed by Hunt and Ryan (2014, Catching on the rebound: Why price elasticities are generally inappropriate measures of rebound effects. Surrey Energy Economics Discussion Paper Series SEEDS 148; 2015, Energy Economics 50, 273) that explicitly relates energy service use with energy source demand and directly incorporates measures of efficiency changes. The results indicate that the rebound effect is relatively high for energy use by Australian households. Due to the unique nature of our household data set, we can examine the influence of demographic and housing characteristics. We find that lowincome households and households with vulnerable members have the largest rebound effects. The relatively large rebound effects found here suggest that consumers gain from efficiency by improved energy services, and thus, policy targeting energy efficiency is not likely to be successful at reducing energy consumption.
Contiguità territoriale e shock sul consumo nelle regioni italiane

Subjects: SECS-P/02 Politica economica

description: The hypothesis of complete consumption risk-sharing suggests that only uninsurable national and international disturbances should affect the growth of the regional consumption. Therefore, the correlation among regional consumption growth rates should be high. This work analyzes the issue of regional consumption risk-sharing in Italy over the period 1971-93. The empirical evidence is mixed: consumption correlations are high but other formal tests suggest the relevance of idiosincratic effects. In conclusion, the overall degree of consumption risk-sharing appears to be less than perfect.
Real Interest Rate and Growth: An Empirical Note

description: Are restrictive monetary policies harmful to growth? The note aims at providing some empirical evidence to answer the question. A significant negative correlation between growth and real interest emerges over the period 1960-94; in the eighties this relationship strengthens. This result is in agreement with the traditional view of a long run positive link between growth and capital accumulation and a negative long run link between accumulation and the cost of capital. Moreover the outcome is in line with the view that links the slowdown in economic growth of the industrial countries over the last decades appears to the implementation of restrictive monetary policies

description: Um eine ausreichende Wirksamkeit von Subunit- und Einzelantigenimpfstoffen zu gewährleisten, sind potente Adjuvanssysteme notwendig. Squalen Nanoemulsionen wie z.B. MF59® stellen dabei zugelassene, sichere und millionenfach verwendete Adjuvantien dar. In der vorliegenden Arbeit wurden squalenhaltige Lipidnanopartikel entwickelt, die mit einem hefebasierten Impfstoff gegen IBDV als applikationsfertige Zubereitung gelagert werden konnten. Mittels DSC, H-NMR und Weitwinkelröntgen wurden die Interaktionen des Squalens mit dem festen Lipid untersucht. Ein breites Methodenspektrum wurde zur detaillierten Größencharakterisierung angewendet, da die Partikelgröße den entscheidenden Faktor für die Wirksamkeit von Squalen Nanopartikeln darstellt. Die entwickelten Adjuvantien wurden mit Freundschem Adjuvans und einer kommerziellen Squalen Nanoemulsionen in Immunisierungsstudien im Mausmodell sowie in Infektionsexperimenten mit einem hoch virulenten IBDV Stamm im Zielorganismus Huhn verglichen.
description: Potent adjuvant systems are required for subunit and single antigen based vaccines to provide sufficient immunogenicity. Squalene nanoemulsions like MF59 are potent, safe and well characterised adjuvant systems and approved for the use in humans. Here, squalene containing solid lipid nanoparticles were developed which can be stored as freeze dried power together with a yeast based vaccine against IBDV. Several methods for detailed size measurement were applied, as the immune stimulating effect of squalene emulsions is mainly dependent on the particle size. DSC, X-Ray and H-NMR studies were performed to characterise the interactions of the incorporated liquid squalene with the solid hard fat matrix. The developed adjuvants were compared with Freund`s adjuvant and a commercially available squalene nanoemulsion in immunisation trials in the mouse model and a challenge experiment with a highly virulent IBDV strain in the target organism chicken.

description: Several hook summation formulae for binary trees have appeared recently in the literature. In this paper we present an analogous formula for unordered increasing trees of size r, which involves r parameters. The right-hand side can be written nicely as a product of linear factors. We study two specializations of this new formula, including Cayley's enumeration of trees with respect to vertex degree. We give three proofs of the hook formula. One of these proofs arises somewhat indirectly, from representation theory of the symmetric groups, and in particular uses Kerov's character polynomials. The other proofs are more direct, and of independent interest.

description: In a model of repeated Cournot competition under complete information, we show that delegation has no effect on cartel stability if managers collude, while it may hinder cartel stability when owners collude in setting the incentive schemes. If owners can choose whether to delegate or keep control of their respective firms, and both groups of individuals collude or play noncooperatively in their respective variables according to the level of intertemporal discount factor, then if managers are not able to collude in output levels, owners' delegation decision is nonmonotone in the discount factor.

description: Theory suggests that the development of common property increases national welfare, and consistent with this thinking Australia’s Murray–Darling Basin (MDB) Plan uses a common property approach to recover environmental water rights in the national interest. Two water recovery instruments are used: purchasing water rights (buyback) from farmers, and saving water by subsidising irrigator adoption of technically efficient technology. A moratorium on buyback has focused environmental recovery on subsidised technically efficient technology adoption. Economists argue that national welfare is maximised via buyback and highlight the limitations of efficiency savings to recover sufficient environmental water. A risk is that water recovery targets may be reduced in future, limiting welfare gains from water reform. This article evaluates possible welfare trade-offs surrounding environmental water recovery outcomes where arbitrary limits on buyback are imposed. Results suggest that, on average, strategies which attempt to obtain >1500 gigalitres (GL) of water from onfarm efficiency investments will only provide sufficient resources to meet environmental objectives in very wet states of nature. We conclude that reliance on technically efficient irrigation infrastructure is less economically efficient relative to water buyback. Importantly, the transformation of MDB irrigation will significantly constrain irrigators’ future capacity to adapt to climate change.

We map products of fermionic operators onto nonlocal spin operators and decompose the resulting dynamics in efficient steps with Trotter methods, yielding an overall protocol that employs only polynomial resources. The proposed scheme can be relevant in a variety of fields as condensed-matter or high-energy physics, where quantum simulations may solve problems intractable for classical computers.

description: We argue that it is logically possible to have a sort of both reality and locality in quantum mechanics. To demonstrate this, we construct a new quantitative model of hidden variables (HV's), dubbed solipsistic HV's, that interpolates between the orthodox no-HV interpretation and nonlocal Bohmian interpretation. In this model, the deterministic point-particle trajectories are associated only with the essential degrees of freedom of the observer, and not with the observed objects. In contrast with Bohmian HV's, nonlocality in solipsistic HV's can be substantially reduced down to microscopic distances inside the observer. Even if such HV's may look philosophically unappealing to many, the mere fact that they are logically possible deserves attention.

description: We derive the invariant measure on the manifold of multimode quantum Gaussian states, induced by the Haar measure on the group of Gaussian unitary transformations. To this end, by introducing a bipartition of the system in two disjoint subsystems, we use a parameterization highlighting the role of nonlocal degrees of freedom -- the symplectic eigenvalues -- which characterize quantum entanglement across the given bipartition. A finite measure is then obtained by imposing a physically motivated energy constraint. By averaging over the local degrees of freedom we finally derive the invariant distribution of the symplectic eigenvalues in some cases of particular interest for applications in quantum optics and quantum information.

Coordinated Beamforming for Multiuser MISO Interference Channel under Rate Outage Constraints

description: This paper studies the coordinated beamforming design problem for the multiple-input single-output (MISO) interference channel, assuming only channel distribution information (CDI) at the transmitters. Under a given requirement on the rate outage probability for receivers, we aim to maximize the system utility (e.g., the weighted sum rate, weighted geometric mean rate, and the weighed harmonic mean rate) subject to the rate outage constraints and individual power constraints. The outage constraints, however, lead to a complicated, nonconvex structure for the considered beamforming design problem and make the optimization problem difficult to handle. {Although} this nonconvex optimization problem can be solved in an exhaustive search manner, this brute-force approach is only feasible when the number of transmitter-receiver pairs is small. For a system with a large number of transmitter-receiver pairs, computationally efficient alternatives are necessary. The focus of this paper is hence on the design of such efficient approximation methods. In particular, by employing semidefinite relaxation (SDR) and first-order approximation techniques, we propose an efficient successive convex approximation (SCA) algorithm that provides high-quality approximate beamforming solutions via solving a sequence of convex approximation problems. The solution thus obtained is further shown to be a stationary point for the SDR of the original outage constrained beamforming design problem. {Furthermore}, we propose a distributed SCA algorithm where each transmitter optimizes its own beamformer using local CDI and information obtained from limited message exchange with the other transmitters. Our simulation results demonstrate that the proposed SCA algorithm and its distributed counterpart indeed converge, and near-optimal performance can be achieved for all the considered system utilities.

description: The paper proposes a quantitative assessment of the impact of demand side factors, i.e. growth, composition and distribution of income, in the determination of changes in the aggregate balance of employment. The level of employment warranted in a system is here derived from the application of a simple scheme which we have called, following the seminal contribution of Richard Kahn in 1931, the "employment multiplier". Starting from an accounting identity between the values of aggregate supply and demand, a level of warranted employment is derived, given the labour coefficient and the deflated values of final demand, in which autonomous components are distinguished from an induced component, this latter depending on total labour income. The variations, over decades and cycles, of aggregate employment for seven OECD countries (France, Italy, Japan, Sweden, United Kingdom, United States and West Germany,), from 1960 onwards, are then analysed and decomposed into the effects of the contributions of three components: growth of average productivity of labour, of "autonomous" demand, and of the "multiplier", a term which summarises the impact of wage share and consumption propensity on induced demand and again on the level of overall employment.
The power of political movement and the collapse of democracy in Thailand
Creators: name: Sinpeng, Vipapat Aim
Publisher: name: University of British Columbia
Year: 2016

description: Why are some opposition movements pro-democracy while others are not? What explains an anti-democratic movement in a democracy? Examining how democratic institutions give rise to a popular anti-democratic movement is the key task this research accomplishes. To answer this question, my dissertation exploits variation across Thailand in terms of the extent to which a popular movement contributes to a collapse of democracy. Based on a within-case comparison of the People's Alliance for Democracy (PAD) Movement, I develop a novel theory called "institutional blockage." It argues that a mobilized society can turn against democracy when their voices are not given appropriate space to channel their grievances within the realms of formal and informal institutions. When people feel blocked from access to power, they rebel against the system by appealing to nondemocratic institutions to regain their power, which then triggers a regime collapse. The argument reveals a paradox that people will support democracy as long as the regime does not marginalize them. The dissertation makes three key contributions. First, the middle class and civil society can act as a force against democracy. The PAD's support base is drawn largely from NGOs and the urban middle class, both of which are often seen as bulwarks for democracy. My research outlines a concrete process in which these two forces turn again democracy, thus surmounting a theoretical and empirical challenge that has confronted previous scholarship. Second, a weakly institutionalized party system, under certain conditions, can contribute to regime survival. New democracies with fluid, patronage-based, non-programmatic party systems constrain political elites from subverting the system. Third, democratic consolidation, particularly concentration of executive power, can threaten the viability of democracy. The theory on institutional blockage and the process of anti-democratic mobilization can shed light on similar movements in Egypt, Venezuela and the Philippines.

description: We characterise the interplay between firms' decision in product development undertaken through a research joing venture (RJV), and the nature of their ensuing market behaviour. Participant firms in an RJV face a trade-off between saving the costs of product inno-vation by developing similar products to one another, e.g. by sharing most of the basic components of their products, and investing higher initial efforts in product innovation in order to develop more distinct products. We prove that the more the firms' products are distinct and thus less substitutable, the easier their collusion is to sustain in the marketing supergame, either in prices (Bertrand) or in quantities (Cournot). This gives rise to a non-monotone and discontinuous relationship between firms' product portfolio and their intertemporal preferences.

description: We examine the firm-specific determinants of technical efficiency in Australian mining companies using data envelopment analysis (DEA). To do so, we employ panel data sourced from individual mining companies listed on the Australian Securities Exchange (ASX) over the period 2010–2014. To ensure valid statistical inference in the presence of serial correlation between DEA efficiency scores, we apply Simar and Wilson’s two-stage bootstrap method. We find that ownership concentration, firm size, firm age, product portfolio, product diversification and growth status significantly contribute to efficiency gains. However, other firm-specific factors, such as capacity utilisation, financial risk and overseas operations appear to have limited impact on the technical efficiency of mining firms.

This behavior is resulted from a sequential avalanche multiplication and two-stage barrier lowering effect. Under normal operation mode, a typical common-emitter current gain of 60 is obtained at collector current density of 400A/cm2 for the studied HEBT without emitter-edge thinning structure.

We have developed a non alloyed and non injecting ohmic contact (NAOC) based on ion implantation to fabricate detectors which can operate at applied voltages greater than the one needed to make them fully depleted. With such a detectors and at high applied voltages, Va > 500 V, a nearly full charge collection efficiency has been achieved for both alpha particles and X-rays. Furthermore the best energy resolution achieved at room temperature has been 1.1% for 5.48 MeV alpha particles and 26.1% for 59.5 keV X-rays, while at -30 °C the best energy resolution measured for X-rays has been 4.1%.

description: We present results concerning propagation of the Gaussian state across the cosmological quantum bounce. The reduced phase space quantization of loop quantum cosmology is applied to the Friedman-Robertson-Walker universe with a free massless scalar field. Evolution of quantum moments of the canonical variables is investigated. The covariance turns out to be a monotonic function so it may be used as an evolution parameter having quantum origin. We show that for the Gaussian state the Universe is least quantum at the bounce. We propose explanation of this counter-intuitive feature using the entropy of squeezing. The obtained time dependence of entropy is in agreement with qualitative predictions based on von Neumann entropy for mixed states. We show that, for the considered Gaussian state, semiclassicality is preserved across the bounce, so there is no cosmic forgetfulness.

description: This article measures farm-level postharvest losses for maize, soya and groundnuts among 1,200 households in Malawi. Farmers answered a detailed questionnaire designed to learn about losses during harvest and transport, processing and storage and which measures both complete losses and crop damage. The findings indicate that fewer than half of households report suffering losses conditional on growing each crop. Conditional on losses occurring, the loss averages between 5 and 12 per cent of the farmer’s total harvest. Compared to nationally representative data that measure losses using a single survey question, this study documents a far greater percentage of farmers experiencing losses. We find that losses are concentrated in harvest and processing activities for groundnuts and maize; for soya, they are highest during processing. Existing interventions have primarily targeted storage activities; however, these results suggest that targeting other activities may be worthwhile.

description: In0.7Al0.3As/InAs/In0.8Ga0.2As modulation-doped heterostructures on GaAs were characterized and HFETs were fabricated. A linearly graded InAlAs buffer was used to transform the lattice constant from that of GaAs to In0.8Ga0.2As Random surface morphology with scattered volcano-like deep holes was observed. The root-mean-square roughness value was 4-7 nm. Most dislocations were confined in the graded buffer and the maximum threading dislocation density in the HFET layers was estimated to be in the order of 106 cm-2. An electron mobility of 1.37.104 cm2/Vs with a carrier density of 1.88.1012 cm-2 at 300 K was achieved. HFETs with a 0.1 um gate length showed an extrinsic transconductance of 750 mS/mm, an extrinsic fT of 90 GHz and an fmax of 225 GHz.

description: Shear flow significantly affects the transport of swimming algae in suspension. For example, viscous and gravitational torques bias bottom-heavy cells to swim towards regions of downwelling fluid (gyrotaxis). It is necessary to understand how such biases affect algal dispersion in natural and industrial flows, especially in view of growing interest in algal photobioreactors. Motivated by this, we here study the dispersion of gyrotactic algae in laminar and turbulent channel flows using direct numerical simulation (DNS) and the analytical swimming dispersion theory of Bees and Croze (2010). Time-resolved dispersion measures are evaluated as functions of the Peclet and Reynolds numbers in upwelling and downwelling flows. For laminar flows, DNS results are compared with theory using competing descriptions of biased swimming cells in shear flow. Excellent agreement is found for predictions that employ generalized-Taylor-dispersion. The results highlight peculiarities of gyrotactic swimmer dispersion relative to passive tracers. In laminar downwelling flow the cell distribution drifts in excess of the mean flow, increasing in magnitude with Peclet number. The cell effective axial diffusivity increases and decreases with Peclet number (for tracers it merely increases). In turbulent flows, gyrotactic effects are weaker, but discernable and manifested as non-zero drift. These results should significantly impact photobioreactor design.

New Equations of State in Simulations of Core-Collapse Supernovae

description: We discuss three new equations of state (EOS) in core-collapse supernova simulations. The new EOS are based on the nuclear statistical equilibrium model of Hempel and Schaffner-Bielich (HS), which includes excluded volume effects and relativistic mean-field (RMF) interactions. We consider the RMF parameterizations TM1, TMA, and FSUgold. These EOS are implemented into our spherically symmetric core-collapse supernova model, which is based on general relativistic radiation hydrodynamics and three-flavor Boltzmann neutrino transport. The results obtained for the new EOS are compared with the widely used EOS of H. Shen et al. and Lattimer & Swesty. The systematic comparison shows that the model description of inhomogeneous nuclear matter is as important as the parameterization of the nuclear interactions for the supernova dynamics and the neutrino signal. Furthermore, several new aspects of nuclear physics are investigated: the HS EOS contains distributions of nuclei, including nuclear shell effects. The appearance of light nuclei, e.g., deuterium and tritium is also explored, which can become as abundant as alphas and free protons. In addition, we investigate the black hole formation in failed core-collapse supernovae, which is mainly determined by the high-density EOS. We find that temperature effects lead to a systematically faster collapse for the non-relativistic LS EOS in comparison to the RMF EOS. We deduce a new correlation for the time until black hole formation, which allows to determine the maximum mass of proto-neutron stars, if the neutrino signal from such a failed supernova would be measured in the future. This would give a constraint for the nuclear EOS at finite entropy, complementary to observations of cold neutron stars.

description: In cereal crops such as barley (Hordeum vulgare L.), pre-anthesis tip degeneration (PTD) starts with growth arrest of the inflorescence meristem dome, which is followed basipetally by the death of floral primordia and the central axis that affects final grain number. Multi-omics analyses and genetic approaches revealed that barley inflorescence PTD is accompanied by sugar depletion, amino acid degradation, and abscisic acid responses involving transcriptional regulators of senescence, defense, and light signaling. Further, GRASSY TILLERS1 (HvGT1), encoding an HD-ZIP transcription factor, was identified as an important modulator of PTD. A gene-edited knockout mutant of HvGT1 delayed PTD and increased differentiated apical spikelets and final spikelet number. Altogether, this study proposes a molecular framework that leads to barley spike PTD, the manipulation of which may increase yield potential in barley and other related cereals. The present study also demonstrated spatial metabolomics in the developing barley inflorescence using the MALDI MSI technique, which reveals novel metabolic pathways and opens new research questions.
description: Bei Getreidepflanzen wie Gerste (Hordeum vulgare L.) beginnt die Degeneration der Blütenstandsspitze (PTD) mit einem Wachstumsstillstand der Blütenstandsmeristemkuppel, dem basal das Absterben der Blütenprimordien und der zentralen Achse folgt, was sich auf die endgültige Kornzahl auswirkt. Multi-omics-Analysen und genetische Ansätze haben gezeigt, dass das Absterben der Blütenstände bei Gerste mit Zuckerabbau, Aminosäureabbau und Abscisinsäure-Reaktionen einhergeht, an denen Transkriptionsregulatoren für Seneszenz, Verteidigung und Lichtsignalgebung beteiligt sind. Darüber hinaus wurde GRASSY TILLERS1 (HvGT1), das für einen HD-ZIP-Transkriptionsfaktor kodiert, als ein wichtiger Modulator der PTD identifiziert. Eine gen-editierte Knockout-Mutante von HvGT1 verzögerte die PTD und erhöhte die Zahl der differenzierten apikalen Ährchen sowie die Zahl der endgültigen Ährchen. Insgesamt wird in dieser Studie ein molekularer Rahmen vorgeschlagen, der zur PTD der Gerstenähre führt und dessen Beeinflussung das Ertragspotenzial von Gerste und anderen verwandten Getreidearten erhöhen könnte. In der vorliegenden Studie wurde auch die räumliche Metabolomik im sich entwickelnden Gerstenblütenstand mit Hilfe der MALDI MSI-Technik nachgewiesen, die neue Stoffwechselwege aufzeigt und neue Forschungsfragen aufwirft.

description: A self aligned complementary HIGFET technology has been developed for high speed/low power digital and microwave analog applications. The process uses 9 lithographic steps including two level of interconnect metal. Typical transconductances of 290 mS/mm and 65 mS/mm are acheived on lum gate length N and P-channel devices respectively. 0.5 um gate length N-HIGFET show a Ft of 40 GHz and an intrinsic Fc of 80 GHz. These devices show promise for incorporation in complementary digital, MMIC and RF power circuits.

Classical limit of the Nelson model with cut off

description: In this paper we analyze the classical limit of the Nelson model with cut off, when both non-relativistic and relativistic particles number goes to infinity. We prove convergence of quantum observables to the solutions of classical equations, and find the evolution of quantum fluctuations around the classical solution. Furthermore we analyze the convergence of transition amplitudes of normal ordered products of creation and annihilation operators between different types of initial states. In particular the limit of normal ordered products between states with a fixed number of both relativistic and non-relativistic particles yields an unexpected quantum residue: instead of the product of classical solutions we obtain an average of the product of solutions corresponding to varying initial conditions.

description: Die vorliegende Dissertation zeigt, dass Fichtes Begründung der praktischen Philosophie kohärent ist und eine argumentative Kontinuität innerhalb seiner Werke besteht. Anhand der Rekonstruktion und Klärung von Termini wie etwa unendliche Tätigkeit, unmittelbares Bewusstsein, Anstoß, Wechselwirkung und Präreflexivät des Ich stelle ich die interne Struktur der Begründung menschlichen Wissens in Fichtes Werken zwischen 1794 und 1799 dar und zeige, dass es keine Inkonsistenz in Fichtes frühen Theorien gibt. Ich stelle die resultierende Struktur der Subjektivität zeitgenössischen Theorie von Autoren wie Korsgaard, Frank, Rosenthal, Kriegel und Nagel gegenüber. Das Ergebnis zeigt nicht nur, dass Fichtes Themen auch heute noch in aktuellen Werken relevant sind, sondern weiterhin, dass Fichtes Theorie eine neue und innovative Perspektive auf die Begründung der aktuellen praktischen Philosophie eröffnet.
description: This doctoral dissertation shows that Fichte’s foundation of practical philosophy is coherent and contains an argumentative continuity throughout his works. Parting from the reconstruction and clarification of such terms as infinite activity of Self, immediate consciousness, Anstoß, Wechselwirkung and pre-reflexivity of Self I demonstrate the internal structure of human knowledge’s foundation as Fichte develops it between 1794 and 1799 and hold that there are no inconsistencies in Fichte’s Jena system. I contrast the resulting structure of subjectivity with contemporary theories such as those developed by Korsgaard, Frank, Rosenthal, Kriegel and Nagel. The results show that not only are Fichte’s topics central to their current works, but also the reconstruction of Fichte’s theory offers a new and innovative perspective on the foundation of practical philosophy as it is discussed in these authors.
