Estoppel (principles?) in public law : the substantive protection of legitimate expectations
Creators: name: Knight, Dean R.
Publisher: name: University of British Columbia
Year: 2009

description: This thesis examines the doctrine of public law estoppel and similar doctrines, such as substantive legitimate expectation, which seek to give substantive protection to people's expectations arising from their dealings with public bodies and officials. The substantive protection of expectations in public law is controversial and this thesis considers whether the concerns raised about its application have any sound basis. I review the case-law in which the courts have considered whether to apply estoppel in public law or otherwise extend the doctrine of legitimate expectation to substantive outcomes. Particular attention is paid to the "spill-over" of estoppel from private law into public law. I discuss whether there is any real difference between the doctrines which seek to give substantive protection to expectations. I conclude there is no material difference between the approaches or their inherent ability to respond to the concerns raised by the opponents of substantive protection. I then consider the notion of legal certainty in the law - the conceptual principle on which the doctrines of estoppel and legitimate expectation are based. I conclude that this principle has a strong foundation and creates a powerful argument for protecting expectations. I then examine the apparent concerns that arise from achieving legal certainty in public law and draw out the specific objections to applying public law estoppel and substantive legitimate expectation. I critique each of these objections and conclude that none of them present an insurmountable hurdle to the application of estoppel or substantive legitimate expectation in public law. I conclude by setting out a number of "touchstones" to assist in the case-by-case assessment of whether expectations should be protected. The touchstones attempt to place a greater emphasis on the underlying theoretical justification for protecting expectations and to ensure the assessment deals with the concerns that were raised about bringing the concept of legal certainty into public law.

description: We describe new measurements of the inclusive and exclusive branching fractions for Psi(2S) transitions to J/Psi using e+e- collision data collected with the CLEO detector operating at CESR. All branching fractions and ratios of branching fractions reported here represent either the most precise measurements to date or the first direct measurements. Indirectly and in combination with other CLEO measurements, we determine B(ChicJ --> gamma J/Psi) and B(Psi(2S) --> light hadrons).

description: Under the Clean Development Mechanism (CDM) of the Kyoto Protocol, forest projects can receive returns for carbon sequestration via two credit instruments: temporary (tCERs) or long-term certified emission reductions (lCERs). This article develops a theoretical model of optimal harvesting strategies that compares private optimal harvest decision under these two instruments. We find that risk neutral landowners are likely to prefer instituting lCERs over tCERs to maximize surplus. A particular type of early harvest penalty implemented under the lCERs is critical in determining the length of rotation intervals and the carbon credit supply. When this penalty is an increasing function of the difference in biomass before and after harvesting across verification periods, the landowner may choose longer or shorter rotation intervals compared to the Faustmann rotation. The resulting supply curve may have a backward bending region over a range of carbon prices.

description: The lamellar cuprate superconductors exhibit the highest ambient-pressure superconducting transition temperatures (T$_C$) and, after more than three decades of extraordinary research activity, continue to pose formidable scientific challenges. A major experimental obstacle has been to distinguish universal phenomena from materials- or technique-dependent ones. Angle-resolved photoemission spectroscopy (ARPES) measures momentum-dependent single-particle electronic excitations and has been invaluable in the endeavor to determine the anisotropic momentum-space properties of the cuprates. HgBa$_2$CuO$_{4+δ}$ (Hg1201) is a single-CuO$_2$-layer cuprate with a particularly high optimal T$_C$ and a simple crystal structure; yet there exists little information from ARPES about the electronic properties of this model system. Here we present an ARPES study of doping-, temperature-, and momentum-dependent systematics of near-nodal dispersion anomalies in Hg1201. The data reveal a hierarchy of three distinct energy scales -a sub-gap low-energy kink, an intermediate-energy kink near 55 meV, and a peak-dip-hump structure. The first two features are attributed to the coupling of electrons to Ba-derived optical phonons and in-plane bond-stretching phonons, respectively. The nodal peak-dip-hump structure appears to have a common doping-dependence in several single-layer cuprates, and is interpreted as a manifestation of pseudogap physics at the node. These results establish several universal phenomena, both in terms of connecting multiple experimental techniques for a single material, and in terms of connecting comparable spectral features in multiple structurally similar cuprates.

description: We study the single-photon transport in the coupled-resonator waveguide (CRW) controlled by an imperfect cavity. A Lorentzian spectrum is introduced to describe the dissipation. We find that the probability current conservation can be broken, although the imperfect cavity is a Hermitian system. The coupling strength between the imperfect cavity and the CRW has significant influences near the resonant frequency. With the increase of the coupling strength, the transmission coefficient becomes smaller. The spectral width plays a dominant role under the off-resonant condition, where the transmission coefficient is greatly suppressed with the increase of the spectral width. We also observe an abrupt jump of the transmission and reflection coefficients when the hopping amplitude is large enough. All the distinctive behaviors are closely related to the complex effective potential induced by the imperfect cavity.

Accurate Discretization Of Poroelasticity Without Darcy Stability -- Stokes-Biot Stability Revisited

description: In this manuscript we focus on the question: what is the correct notion of Stokes-Biot stability? Stokes-Biot stable discretizations have been introduced, independently by several authors, as a means of discretizing Biot's equations of poroelasticity; such schemes retain their stability and convergence properties, with respect to appropriately defined norms, in the context of a vanishing storage coefficient and a vanishing hydraulic conductivity. The basic premise of a Stokes-Biot stable discretization is: one part Stokes stability and one part mixed Darcy stability. In this manuscript we remark on the observation that the latter condition can be generalized to a wider class of discrete spaces. In particular: a parameter-uniform inf-sup condition for a mixed Darcy sub-problem is not strictly necessary to retain the practical advantages currently enjoyed by the class of Stokes-Biot stable Euler-Galerkin discretization schemes.

description: This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and improve the economic efficiency of a mitigation policy package? To answer these questions, we use an integrated assessment model with multiple externalities and an endogenous representation of technical progress in the energy sector. We evaluate a range of innovation policies, both as a stand-alone instrument and in combination with other mitigation policies. Even under fairly optimistic assumptions about the funding available for, and the returns to R&D, our analysis indicates that innovation policies alone are unlikely to stabilise global concentration and temperature. The efficiency gains of combining innovation and carbon pricing policies are found to reach about 10% for a stabilisation target of 535 ppm CO2eq. However, such gains are reduced when more plausible (sub-optimal) global innovation policy arrangements are considered.
AdS twistors for higher spin theory

Subjects: subject: High Energy Physics - Theory (hep-th)
subject: FOS: Physical sciences

description: We construct spectra of supersymmetric higher spin theories in D=4, 5 and 7 from twistors describing massless (super-)particles on AdS spaces. A massless twistor transform is derived in a geometric way from classical kinematics. Relaxing the spin-shell constraints on twistor space gives an infinite tower of massless states of a ``higher spin particle'', generalising previous work of Bandos et al. This can generically be done in a number of ways, each defining the states of a distinct higher spin theory, and the method provides a systematic way of finding these. We reproduce known results in D=4, minimal supersymmetric 5- and 7-dimensional models, as well as supersymmetrisations of Vasiliev's Sp-models as special cases. In the latter models a dimensional enhancement takes place, meaning that the theory lives on a space of higher dimension than the original AdS space, and becomes a theory of doubletons. This talk was presented at the XIXth Max Born Symposium ``Fundamental Interactions and Twistor-Like Methods'', September 2004, in Wroclaw, Poland.

description: The current rechargeable battery technologies have a failure in their performance at high pressure and temperature. In this article, we have brought theoretical insights on using boron nitride flakes as a protecting layer for a lithium-ion battery device and extended its application for a spin-dependent photon emission device. Hence, the electronic properties of pristine and lithium-doped hydrogen-edged boron nitride flakes have been studied by the first principle density functional theory calculations. In this study, we have discussed the stability, adsorption energies, bond lengths, electronic gaps, frontier molecular orbitals, the density of states, charge distributions, and dipole moments of pristine and lithium hydrogen-edged doped boron nitride flakes.
Extremely asymmetrical scattering in gratings with varying mean structural parameters

description: Extremely asymmetrical scattering (EAS) is an unusual type of Bragg scattering in slanted periodic gratings with the scattered wave (the +1 diffracted order) propagating parallel to the grating boundaries. Here, a unique and strong sensitivity of EAS to small stepwise variations of mean structural parameters at the grating boundaries is predicted theoretically (by means of approximate and rigorous analyses) for bulk TE electromagnetic waves and slab optical modes of arbitrary polarization in holographic (for bulk waves) and corrugation (for slab modes) gratings. The predicted effects are explained using one of the main physical reasons for EAS--the diffractional divergence of the scattered wave (similar to divergence of a laser beam). The approximate method of analysis is based on this understanding of the role of the divergence of the scattered wave, while the rigorous analysis uses the enhanced T-matrix algorithm. The effect of small and large stepwise variations of the mean permittivity at the grating boundaries is analysed. Two distinctly different and unusual patterns of EAS are predicted in the cases of wide and narrow (compared to a critical width) gratings. Comparison between the approximate and rigorous theories is carried out.

Multifragmentation and the liquid-gas phase transition: an experimental overview

Year: 2004
Subjects: subject: Nuclear Experiment (nucl-ex)
subject: FOS: Physical sciences

description: Two roads are presently being followed in order to establish the existence of a liquid-gas phase transition in finite nuclear systems from nuclear reactions at high energy. The clean experiment of observing the thermodynamic properties of a finite number of nucleons in a container is presently only possible with the computer. Performed with advanced nuclear transport models, it has revealed the first-order character of the transition and allowed the extraction of the pertinent thermodynamic parameters. The validity of the applied theory is being confirmed by comparing its predictions for heavy-ion reactions with exclusive experiments. The second approach is experimentally more direct. Signals of the transition are searched for by analysing reaction data within the framework of thermodynamics of small systems. A variety of potential signals has been investigated and found to be qualitatively consistent with the expectations for the phase transition. Many of them are well reproduced with percolation models which places the nuclear fragmentation into the more general context of partitioning phenomena in finite systems. A wealth of new data on this subject has been obtained in recent experiments, some of them with a new generation of multi-detector devices aiming at higher resolutions, isotopic identification of the fragments, and the coincident detection of neutrons. Isotopic effects in multifragmentation were addressed quite intensively, with particular attention being given to their relation to the symmetry energy and its dependence on density.

In order of agribusiness expression and importance for the country, considerations about the influence of these plans into Brazilian productivity have become increasable relevant. The present paper has as a proposal (1) a comparative analyses of each PAP’ characteristics, in the period of 2000/2001 to 2005/2006, studying the official documents published by the Agricultural, Livestock and Food Supply Ministry; (2) a prospective investigation of productivity datas offered by IBGE/Embrapa and; (3) provide, from simple statistical approach and inference, the real performance of livestock in the last six years, and (4) offer bases that help in formulating hypotheses about the programs effectiveness. Recalculated the productivity index, considering the progress in the disposal of matrices since 2001, concluding by the presence of bias in the indicator. The productivity examination, result in positive performance, but lower than recognized. The figures obtained do not have strong enough to unequivocally independent of environmental variables.

description: We introduce a scheme based on machine learning and deep neural networks to model the environmental dependence of the electronic polarizability in insulating materials. Application to liquid water shows that training the network with a relatively small number of molecular configurations is sufficient to predict the polarizability of arbitrary liquid configurations in close agreement with ab initio density functional theory calculations. In combination with a neural network representation of the interatomic potential energy surface,the scheme allows us to calculate the Raman spectra along 2-nanosecond classical trajectories at different temperatures for H2O and D2O. The vast gains in efficiency provided by the machine learning approach enable longer trajectories and larger system sizes relative to ab initio methods, reducing the statistical error and improving the resolution of the low-frequency Raman spectra. Decomposing the spectra into intramolecular and intermolecular contributions elucidates the mechanisms behind the temperature dependence of the low-frequency and stretch modes.
Criminalizing pleasure: cannabis prohibition in Canada
Creators: name: Tousaw, Kierk I.
Publisher: name: University of British Columbia
Year: 2009

description: Cannabis prohibition is a contentious issue that has been studied extensively by government and the courts. The empirical evidence, in both forums and over time, is remarkably consistent. Cannabis use poses little or no threat of harm to the typical user. Some members of vulnerable groups, however, may be at risk of harm from cannabis use. Whether prohibition is justified on the basis of protecting these vulnerable groups from self-inflicted harm is a question that tests the proper boundaries of criminal law and requires analysis of certain legal philosophies including paternalism and liberalism as evidenced by John Stuart Mill's harm principle. This paper reviews the major government studies of cannabis use and policy. In addition, the paper reviews the main Charter challenge to cannabis prohibition that were recently decided by the Supreme Court of Canada. Ultimately, the government inquiries all call for reform of Canada's cannabis laws. Despite this, Canada's policy toward cannabis has remained virtually unchanged since its inception in 1923. The Supreme Court recently rejected the Charter challenge, leaving any hope of reform in the hand of Parliament. Reform seems unlikely because certain themes of prohibition, such as the assumption that it has a deterrent effect, continue to find resonance despite empirical evidence to the contrary. The power of the status quo, it seems, is very difficult to overcome.

The Centauro algorithm is longitudinally invariant and can cluster jets with Born kinematics, which enables novel studies of transverse-momentum-dependent observables. Furthermore, we show that spherically-invariant algorithms in the Breit frame give access to low-energy jets from current fragmentation. We propose novel studies in unpolarized, polarized, and nuclear DIS at the future Electron-Ion Collider.

description: Axion-like fields heavier than about $10^{-27}$eV are expected to oscillate in the radiation dominated epoch when the Hubble parameter drops below their mass. Considering the Chern-Simons coupling with a dark gauge boson, large amount of dark photons are produced during a short time interval through tachyonic resonance instability. The produced dark photons then source gravitational tensor modes leading to chiral gravitational waves. Through this process, one can indirectly probe a large parameter space of coupled axion-dark photon models. In this work we first find an analytic expression for the number density of the dark photons produced during the tachyonic resonance regime. Second, by using the saddle point approximation we find an analytic expression for the gravitational wave spectrum in terms of the mass, coupling and misalignment angle. Our analytic results can be used for the observational analysis of these types of scenarios.

description: This article aimed to study the quality of the jobs generated by the shrimp maturation and hatchery laboratories in Barreta Beach, RN, Brazil, in a context of informality and impoverished work conditions. The study was done among workers in two laboratories, using a questionnaire, to verify the existence of a set of aspects of the work relationship - such as shift length, social obligations, accident hazards, fringe benefits, occupational diseases, among others – and to analyze the quality of the jobs. Examining the data, it became apparent that the jobs generated were considered of good quality, as they met a number of important labor relationship requirements cited in the literature. However, this result must be seen in light of the extremely impoverished work conditions. It is also important to consider that one of the limitations of the study was the impossibility to generalize the data to the entire sea shrimp cultivation sector. Despite this fact, the objectives of the research were fully met and the profile made of the jobs generated by the shrimp farming sector was important in outlining public policies which aim at fomenting this activity.

description: We report an ab-initio investigation of several possible Si and Ge pristine nanowires with diameters between 0.5 and 1.2 nm. We considered nanowires based on the diamond structure, high-density bulk structures, and fullerene-like structures. We find that the diamond structure nanowires are unstable for diameters smaller than 1 nm, and undergo considerable structural transformations towards amorphous-like wires. Such instability is consistent with a continuum model that predicts, for both Si and Ge, a stability crossover between diamond and high-density-structure nanowires for diameters smaller than 1 nm. For diameters between 0.8 nm and 1 nm, filled-fullerene wires are the most stable ones. For even smaller diameters (d~0.5 nm), we find that a simple hexagonal structure is particularly stable for both Si and Ge.

description: Non-parallel many-to-many voice conversion remains an interesting but challenging speech processing task. Many style-transfer-inspired methods such as generative adversarial networks (GANs) and variational autoencoders (VAEs) have been proposed. Recently, AutoVC, a conditional autoencoders (CAEs) based method achieved state-of-the-art results by disentangling the speaker identity and speech content using information-constraining bottlenecks, and it achieves zero-shot conversion by swapping in a different speaker's identity embedding to synthesize a new voice. However, we found that while speaker identity is disentangled from speech content, a significant amount of prosodic information, such as source F0, leaks through the bottleneck, causing target F0 to fluctuate unnaturally. Furthermore, AutoVC has no control of the converted F0 and thus unsuitable for many applications. In the paper, we modified and improved autoencoder-based voice conversion to disentangle content, F0, and speaker identity at the same time. Therefore, we can control the F0 contour, generate speech with F0 consistent with the target speaker, and significantly improve quality and similarity. We support our improvement through quantitative and qualitative analysis.
Self-Calibration of Cluster Dark Energy Studies: Observable-Mass Distribution

Publisher: name: arXiv
Year: 2005
Subjects: subject: Astrophysics (astro-ph)
subject: FOS: Physical sciences

description: The exponential sensitivity of cluster number counts to the properties of the dark energy implies a comparable sensitivity to not only the mean but also the actual_distribution_ of an observable mass proxy given the true cluster mass. For example a 25% scatter in mass can provide a ~50% change in the number counts at z~2 for the upcoming SPT survey. Uncertainty in the scatter of this amount would degrade dark energy constraints to uninteresting levels. Given the shape of the actual mass function, the properties of the distribution may be internally monitored by the shape of the_observable_ mass function. An arbitrary evolution of the scatter of a mass-independent Gaussian distribution may be self-calibrated to allow a measurement of the dark energy equation of state of Delta w ~0.1. External constraints on the mass_variance_ of the distribution that are more accurate than Delta var < 0.01 at z~1 can further improve constraints by up to a factor of 2. More generally, cluster counts and their sample variance measured as a function of the observable provide internal consistency checks on the assumed form of the observable-mass distribution that will protect against misinterpretation of the dark energy constraints.

Supersymmetric Standard Model Spectra from RCFT orientifolds

description: We present supersymmetric, tadpole-free d=4,N=1 orientifold vacua with a three family chiral fermion spectrum that is identical to that of the Standard Model. Starting with all simple current orientifolds of all Gepner models we perform a systematic search for such spectra. We consider several variations of the standard four-stack intersection brane realization of the standard model, with all quarks and leptons realized as bifundamentals and perturbatively exact baryon and lepton number symmetries, and with a U(1)_Y vector boson that does not acquire a mass from Green-Schwarz terms. The number of supersymmetric Higgs pairs H_1 + H_2 is left free. In order to cancel all tadpoles, we allow a "hidden" gauge group, which must bechirally decoupled from the standard model. We also allow for non-chiral mirror-pairs of quarks and leptons, non-chiral exotics and (possibly chiral) hidden, standard model singlet matter, as well as a massless B-L vector boson. All of these less desirable features are absent in some cases, although not simultaneously. In particular, we found cases with massless Chan-Paton gauge bosons generating nothing more than SU(3) x SU(2) x U(1). We obtain almost 180000 rationally distinct solutions (not counting hidden sector degrees of freedom), and present distributions of various quantities. We analyse the tree level gauge couplings, and find a large range of values, remarkably centered around the unification point.

Atomic Structure of Hematite ($α$-Fe$_2$O$_3$) Nanocube Surface; Synchrotron X-ray Diffraction Study

description: Atomic structure of a mono-dispersive hematite ($α$-Fe$_2$O$_3$) nanocube $(0 1\bar1 2)$ surface was determined with synchrotron X-ray diffraction. The $α$-Fe$_2$O$_3$ nanocubes were prepared through a hydrothermal process and a single layer of nanocubes was deposited on a silicon substrate with a drop cast method. The alignment of nanocubes with their $(0 1\bar1 2)$ surfaces parallel to the substrate is confirmed with grazing incidence X-ray diffraction. Specular crystal truncation rods (CTR's) from as-prepared and vacuum annealed nanocube surfaces have been measured and they are drastically different from previously reported CTR's from macroscopic single crystal $(0 1\bar1 2)$ surfaces. The measured CTR's from nanocube surfaces are explained well with the atomic structure models of half of atoms in top Fe layer being missing while extra oxygen-layers cover the half-missing Fe layer. An acidic environment during hydrothermal nanocube synthesis process is proposed as the main cause of the difference.

description: Adversities, generally, have the capacity to generate behaviors that aggregate people. The objective of this work is to propose an analytical structure, using approaches such as social entrepreneurship, culture, knowledge and cooperation, to treat systematically the competitiveness dilemma that agricultural cooperatives face. The premise of this structure is that the social entrepreneurship that supports organizations such as agricultural cooperatives brings together culture, knowledge and a cooperative stance, which tend to influence the performance of the organization through their presence in its other internal factors. The basic concept of a cooperative organization is its most important differentiating factor because it presupposes that the purpose of the system is not merely financial. While organizations in general need to build value systems that incorporate social-environmental concerns in their structure, cooperative organizations are built on this kind of value system.

description: This brief reviews results of applied research regarding the role of government in staple food markets in East and Southern Africa. The purpose of the brief is to draw lessons for Mozambique as it decides how to use the grain storage silos it has been building since 2009. The authors suggest that: Mozambique is in an unusually strong position to take advantage of private sector activity to stabilize prices over time and space; Additional investment in road and rail infrastructure, incentives, and institutions, would help bring down transaction costs and allow private action to further stabilize prices; Additional stabilization, for those times when Mozambique has to rely on imports from the world market beyond what they normally make, could be obtained in a cost efficient manner using a financial reserve; and If the government chooses also to maintain a public physical reserve, then several conditions (listed in the brief) are necessary for operating this in a manner that improves market performance.

Interpolation categories for homology theories

description: For a homological functor from a triangulated category to an abelian category satisfying some technical assumptions we construct a tower of interpolation categories. These are categories over which the functor factorizes and which capture more and more information according to the injective dimension of the images of the functor. The categories are obtained by proving the existence of truncated versions of resolution or $E_2$-model structures. Examples of functors fitting in our framework are given by every generalized homology theory represented by a ring spectrum satisfying the Adams-Atiyah condition. The constructions are closely related to the modified Adams spectral sequence and give a very conceptual approach to the associated moduli problem and obstruction theory. As application we establish an isomorphism between certain E(n)-local Picard groups and some Ext-groups.

Casting the naturalization of asylum seekers as an economic problem

description: The naturalization of asylum seekers is modeled as an economic problem. In choosing their level of investment in host-country-specific human capital, asylum seekers take into consideration the probability of their being naturalized. The government of the host country chooses the probability of naturalization that most encourages the acquisition of such human capital. That human capital, in turn, increases the asylum seekers’ productivity and earnings and, consequently, maximizes the government’s tax receipts if the asylum seekers are allowed to stay permanently. Conditions are presented under which the optimal level of investment in the host-country-specific human capital is positive, and rises in the probability of naturalization. The asylum seeker’s rational response to the probability of (legal) long-term residency is incorporated in the government’s optimization process. Thus, both the asylum seekers and the government of their host country are modeled as optimizing economic agents in a setting not of their own choosing.

description: We present evidence for an ultrafast optically induced ferromagnetic alignment of antiferromagnetic Mn in Co/Mn multilayers. We observe the transient ferromagnetic signal at the arrival of the pump pulse at the Mn L$_3$ resonance using x-ray magnetic circular dichroism in reflectivity. The timescale of the effect is comparable to the duration of the excitation and occurs before the magnetization in Co is quenched. Theoretical calculations point to the imbalanced population of Mn unoccupied states caused by the Co interface for the emergence of this transient ferromagnetic state.
