description: This paper presents results of research that investigates if long hours of work spent by children in fuel wood collection and water collection activities, hereafter referred to as resource (collection) work, are related to the probability that a child aged 6-14 will attend school. Possible endogeneity of resource work hours is corrected for, using two-stage conditional maximum likelihood estimation. Using data from a 1997-98 Malawi Integrated Household Survey (IHS) conducted by the National Statistics Office (NSO), the study finds that children are significantly involved in resource collection work and their probability of attending school decreases with increases in hours spent on this work. The study further shows that girls spend more hours on resource work and are more likely to be going to school while burdened by this work. Consequently, girls may find it difficult to progress well in school. However, girls are not necessarily less likely to be attending school. The results further show that presence of more women in a household is associated with a lower burden of resource work on children and a higher probability of children's school attendance while that of men is not. Finally, the study shows that children from the most environmentally degraded districts of central and southern Malawi are less likely to attend school and few of them have progressed to secondary school compared to those from the north region districts.

description: Appeals for targeting agricultural R&D in developing countries more explicitly to the needs of poor smallholders in marginal areas are often countered by arguments of efficiency. Others, however, taking a political economy perspective, argue that there is a bias in the selection of agricultural R&D projects towards commercial farmers in the better agricultural areas. In this paper, we try to bring the two perspectives together and illustrate how they interact. We analyze R&D budget allocation assuming two distinct R&D opportunity curves - one for poor smallholders and one for large commercial farmers. We find that, in contrast to the actual allocation of research resources, an efficient allocation (i.e., equalizing the marginal rate of return between the two portfolios) would increase the budget for smallholder projects by 29% and decrease that of commercial farmer projects by 26%. Total economic welfare would increase with 2.1% and there is a modest distributional effect: smallholder welfare increases by 14% and commercial farmer welfare decreases by 11%. In other words, more efficiency in the selection of agricultural R&D projects favors poor smallholders. We also analyze the effects of a premium on research benefits accruing to smallholders and find them to be limited. Rather than trying to shift the R&D opportunity curve artificially, we conclude that policies that can help to increase the profitability of research investments across the board (such as investment in infrastructure, development of markets, and education) and hence shift the R&D opportunity curve for poor smallholders outwards should be pursued more vigorously.

description: The conductance G of a pair of single-channel point contacts in series, one of which is a spin filter, increases from 1/2 to 2/3 x e^2/h with more and more spin-flip scattering. This excess conductance was observed in a quantum dot by Zumbuhl et al., and proposed as a measure for the spin relaxation time T_1. Here we present a quantum mechanical theory for the effect in a chaotic quantum dot (mean level spacing Delta, dephasing time tau_phi, charging energy e^2/C), in order to answer the question whether T_1 can be determined independently of tau_phi and C. We find that this is possible in a time-reversal-symmetry-breaking magnetic field, when the average conductance follows closely the formula =(2e^2/h)(T_1+h/Delta)/(4T_1+3h/Delta).

description: My grandmother's cousin, Private Albert Arthur Spiers, number 3318. 1st/7th Bn. London Regiment, wrote ten letters to her from various parts of the front in France. He writes cheeky, happy letters, but also talks of life in the trenches and the mud. In his last letter, he makes plans to see her shortly when he returns home on leave. However, he was killed on 21st May 1916. The regimental diary states; "During the morning enemy fire was extremely heavy, especially minewerfers. One detached post (Lieut Long & 20 men) were completely wiped." Albert's name is on the Arras Memorial, in the Faubourg-d' Amiens Cemetery. The Memorial commemorates 35,700 casualties who have no known grave. The original letters were handed down to me by my mother and are part of our family archive.

description: The decision of whether to release transgenic crops in the EU is one subject to flexibility, uncertainty, and irreversibility. We analyse the case of herbicide tolerant sugar beet and reassess whether the 1998 de facto moratorium of the EU on transgenic crops for sugar beet was correct from a cost-benefit perspective using a real option approach. We show that the decision was correct, if households value possible annual irreversible costs of herbicide tolerant sugar beet with about 1 Euro or more on average. On the other hand, the total net private reversible benefits forgone if the de facto moratorium is not lifted are in the order of 169 Mio Euro per year.

description: We consider physical processes caused by the twisted photons for a wide range of energy scales, from optical (eV) to nuclear (MeV) to high-energy gamma-rays (TeV). We demonstrate that in order to satisfy angular momentum conservation, absorption of a twisted photon leads to a transverse recoil of the final particle or a system of particles leading to increased threshold energy required for the reaction to proceed. Modification of the threshold energy is predicted for (a) Photo-absorption on colds trapped ions of $^{40}$Ca, along with emerging new transverse-motion sidebands, (b) photo-disintegration of deuterium and (c) photo-production of electron-positron pairs in astrophysics environment.

description: We report on measurements of the crystal structure and hole density in a series of as-grown and annealed GaMnAs samples. The measured hole densities are used to obtain the fraction of incorporated Mn atoms occupying interstitial and substitutional sites. This allows us to make a direct comparison of the measured lattice parameters with recent density functional theory (DFT) predictions. We find that the decrease in lattice constant observed on annealing is smaller than that predicted due to the out diffusion of interstitial Mn during annealing. The measured lattice parameters after annealing are still significantly larger than that of GaAs even in samples with very low compensation. This indicates that the intrinsic lattice parameter of GaMnAs is significantly larger than that of GaAs, in contradiction to the DFT prediction.

description: We address the issue of gravitational radiation in the context of the Bondi-Sachs space-time, and consider the expression for the gravitational energy of the radiation obtained in the realm of the teleparallel equivalent of general relativity (TEGR). This expression is independent of the radial distance (i.e., of powers of $1/r$) and depends exclusively on the functions $c(u,θ,ϕ)$ and $d(u,θ,ϕ)$, which yield the news functions ($u$ is the retarded time, $u=t-r$). We investigate the mathematical and physical features of this energy expression in the simpler framework of axial symmetry. Once a burst of gravitational radiation takes place in a self gravitating system, that leads to a loss of the Bondi mass, gravitational radiation is emitted throughout the whole space-time. The existence and presence of this radiation in the background structure of the space-time is consistent with the analysis developed by Papapetrou, and Hallidy and Janis, who found no proof that a gravitational system that emits a burst of gravitational radiation is preceded and followed by two stationary gravitational field configurations, namely, it seems that it is impossible for a gravitational system, which is initially stationary, to return to a stationary state after emitting a burst of axially symmetric gravitational radiation, in which case the space-time is not even asymptotically stationary. Therefore, it is plausible that the gravitational energy of radiation is present in the background structure of the space-time, and this is the energy predicted in the TEGR. This analysis lead us to conjecture that the noise detected in the large terrestrial gravitational wave observatories is intrinsically related to the background gravitational radiation.

description: The adaptive learning capabilities seen in biological neural networks are largely a product of the self-modifying behavior emerging from online plastic changes in synaptic connectivity. Current methods in Reinforcement Learning (RL) only adjust to new interactions after reflection over a specified time interval, preventing the emergence of online adaptivity. Recent work addressing this by endowing artificial neural networks with neuromodulated plasticity have been shown to improve performance on simple RL tasks trained using backpropagation, but have yet to scale up to larger problems. Here we study the problem of meta-learning in a challenging quadruped domain, where each leg of the quadruped has a chance of becoming unusable, requiring the agent to adapt by continuing locomotion with the remaining limbs. Results demonstrate that agents evolved using self-modifying plastic networks are more capable of adapting to complex meta-learning learning tasks, even outperforming the same network updated using gradient-based algorithms while taking less time to train.

Using the WKB approximation combined with complex-integration technique, we show that the real part of the frequency disappears in the highly damped limit. If we use the Bohr's correspondence principle, the area spectrum of this black hole is continuous. We discuss its implication in the loop quantum gravity.

description: In this paper the incremental values of water are calculated for irrigators in the Fish-Sundays Scheme of South Africa's Eastern Cape province. The socio-political pressure for redistribution of agricultural resources provided the imperative for this study. The model of the Fish-Sundays Scheme reflects a survey of 50 000ha of fodder and citrus production. It explicitly models the water demand on sixteen typical farms, for five irrigation technologies, six crops and four livestock activities. The existing allocation generates an average value of R0.0423/m3/year, which increases to R0.0681/m3/year if farmer-to-farmer trading is allowed given existing infrastructure. Unrestricted trade raises the average value to R0.0719/m3/year. The marginal cost of additional water in the source basin is R0.05/m3/year for the first 315 million m3 and R1.27/m3/year to extend capacity beyond that.

description: We consider entanglement detection for quantum key distribution systems that use two signal states and continuous variable measurements. This problem can be formulated as a separability problem in a qubit-mode system. To verify entanglement, we introduce an object that combines the covariance matrix of the mode with the density matrix of the qubit. We derive necessary separability criteria for this scenario. These criteria can be readily evaluated using semidefinite programming and we apply them to the specific quantum key distribution protocol.

description: I bought this medal on ebay. I have not been able to find anything about it, yet thousands of them must have been struck. One side states: 'This medal was struck in honour of Bradford's sons who so nobly responded & fought for King, Home and Country in the Great European War commencing August 4th 1914. The reverse shows Bradford town hall with a column of soldiers marching away from it, with the statement: 'Bradford's Army over 16,000.' In July 1916 the editor of the Bradford Daily Telegraph reckoned that 30,000 Bradford men were in uniform. This leads me to suggest that the medal was struck between late 1914 and late 1915.

description: Light-matter interaction in quantum materials presents a new paradigm as light can tip the balance between many competing quantum many-body phases to result in new phenomena. Describing the optical response of such materials requires complex models. Here, we develop a non-local model to describe the optical response of a quantum material, 1T-TaS$_2$. 1T-TaS$_2$ is a nearly commensurate charge-density-wave material at room temperature. The competing stacking configurations of the charge domains in this layered material result in significant optical inhomogeneity that necessitates a non-local dielectric function. We experimentally measure the non-local optical response of 1T-TaS$_2$ films under various illumination intensities and validate our model. The non-local parameter extracted from our measurements sheds light on the competition between the two stacking configurations of 1T-TaS$_2$. Our technique of measuring non-local optical response serves as a quick, simple, and non-invasive method to probe the energy landscape of strong correlations in many such quantum materials.

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

description: We present generic form of the covariant nonlocal action for infrared modifications of Einstein theory recently suggested within the weak-field curvature expansion. In the lowest order it is determined by two nonlocal operators -- kernels of Ricci tensor and scalar quadratic forms. In models with a low strong-coupling scale this action also incorporates the strongly coupled mode which cannot be perturbatively integrated out in terms of the metric field. This mode enters the action as a Lagrange multiplier for the constraint on metric variables which reduces to the curvature scalar and enforces the latter to vanish on shell. Generic structure of the action is demonstrated on the examples of the Fierz-Pauli and Dvali-Gabadadze-Porrati models and their extensions. The gauge-dependence status of the strong-coupling and VDVZ problems is briefly discussed along with the manifestly gauge-invariant formalism of handling the braneworld gravitational models at classical and quantum levels.

description: On farm conservation of crop diversity entails policy challenges, especially when the diversity of crops maintained on farms has both inter-specific (among crops) and infra-specific (within a crop) components. Survey data is used to compare the determinants of inter- and infra-specific diversity on household farms in the highlands of northern Ethiopia. Physical features of the farm, and household characteristics such as livestock assets and the proportion of adults that are men, have large and significant effects on both the diversity among and within cereal crops grown, varying among crops. Demographic aspects such as age of household head and adult education levels affect only infra-specific diversity of cereals. Though there are no apparent trade-offs between policies that would enhance one type of diversity (richness) versus another (evenness), those designed to encourage infra-specific diversity in one cereal crop might have the opposite effect on another crop. Trade-offs between development and diversity in this resource-poor system are not evident. Market-related variables and population density have ambiguous effects. Education positively influences cereal crop diversity. Growing modern varieties of maize or wheat does not detract from the richness or evenness of these cereals on household farms.

description: Recent discovery of the afterglow emission from short gamma-ray bursts suggests that binary neutron star or black hole-neutron star binary mergers are the likely progenitors of these short bursts. The accretion of neutron star material and its subsequent ejection by the central engine implies a neutron-rich outflow. We consider here a neutron-rich relativistic jet model of short bursts, and investigate the high energy neutrino and photon emission as neutrons and protons decouple from each other. We find that upcoming neutrino telescopes are unlikley to detect the 50 GeV neutrinos expected in this model. For bursts at z~0.1, we find that GLAST and ground-based Cherenkov telescopes should be able to detect prompt 100 MeV and 100 GeV photon signatures, respectively, which may help test the neutron star merger progenitor identification.

Research led technological change in agriculture generates sufficient productivity growth to give high rates of return in African and Asia and has a substantial impact on poverty, currently reducing this number by 27 million per annum, whereas productivity growth in industry and services has no impact. The per capita "cost" of poverty reduction by means of agricultural research expenditures in Africa is $144 and in Asia $180, or 50 cents per day, but this is covered by output growth. By contrast, the per capita cost for the richer countries of Latin America is over $11,000.

description: It is presented a thorough analysis of scalar perturbations in the background of Gauss-Bonnet, Gauss-Bonnet-de Sitter and Gauss-Bonnet-anti-de Sitter black hole spacetimes. The perturbations are considered both in frequency and time domain. The dependence of the scalar field evolution on the values of the cosmological constant $Λ$ and the Gauss-Bonnet coupling $α$ is investigated. For Gauss-Bonnet and Gauss-Bonnet-de Sitter black holes, at asymptotically late times either power-law or exponential tails dominate, while for Gauss-Bonnet-anti-de Sitter black hole, the quasinormal modes govern the scalar field decay at all times. The power-law tails at asymptotically late times for odd-dimensional Gauss-Bonnet black holes does not depend on $α$, even though the black hole metric contains $α$ as a new parameter. The corrections to quasinormal spectrum due to Gauss-Bonnet coupling is not small and should not be neglected. For the limit of near extremal value of the (positive) cosmological constant and pure de Sitter and anti-de Sitter modes in Gauss-Bonnet gravity we have found analytical expressions.

description: This paper analyses the impact of adopting or rejecting genetically modified GM crops in the EU, taking into account the European Union's Common Agricultural Policy (CAP). In this paper the productivity impact of GMs differs across crops, as it takes factor biased technology change into account. The transfer of knowledge across countries is modelled as a process of endogenous knowledge spillovers. Analyses with a multi-region applied general equilibrium model shows that the CAP protects farm income and production from not adopting GM crops in the EU but has costs in terms of welfare. The EU will forgo substantial benefits if it banned GM imports.

We then try to detect these methods using appropriately constructed neural networks. Experimental results accompany the proposed solutions on the generated data, showing a considerable manipulation detection level.

description: We compare the properties of halo coronal mass ejections (CMEs) that originate close to the limb (within a central meridian distance range of 60 to 90 deg) during solar cycles 23 and 24 to quantify the effect of the heliospheric state on CME properties. There are 44 and 38 limb halos in the cycles 23 and 24, respectively. Normalized to the cycle-averaged total sunspot number, there are 42 percent more limb halos in cycle 24. Although the limb halos as a population is very fast (average speed 1464 km s-1), cycle-24 halos are slower by 26 percent than the cycle-23 halos. We introduce a new parameter, the heliocentric distance of the CME leading edge at the time a CME becomes a full halo; this height is significantly shorter in cycle 24 (by 20 percent) and has a lower cutoff at 6 Rs. These results show that cycle-24 CMEs become halos sooner and at a lower speed than the cycle-23 ones. On the other hand, the flare sizes are very similar in the two cycles, ruling out the possibility of eruption characteristics contributing to the differing CME properties. In summary, this study reveals the effect of the reduced total pressure in the heliosphere that allows cycle-24 CMEs expand more and become halos sooner than in cycle 23. Our findings have important implications for the space-weather consequences of CMEs in cycle 25 (predicted to be similar to cycle 24) and for understanding the disparity in halo counts reported by automatic and manual catalogs.

Between concepts and context: protection of "personal freedom" : a comparative case study of German and Canadian criminal law
Creators: name: Heidt, Anne-Katrin
Publisher: name: University of British Columbia
Year: 2009

description: Due to its pervasive affinity for conceptual abstractions, German criminal law has been said to suffer from a rationalist hubris that leads to the formulation of artificial rules and lacks respect for the realities of life. The following study will examine this hypothesis with respect to one area of German criminal law that is particularly characterized by an abstract, conceptual way of thinking: the area of what in Germany is called "offences against personal freedom". A case where a store detective suggested to a 16 year old female shoplifter that he would abstain from making a larceny report to the police if she engaged in sexual intercourse with him has caused a lot of debate in German criminal law as to the question of whether the detective infringed the shoplifter's "personal freedom" in a way prohibited by criminal law. This debate will be presented and contrasted with the approach Canadian criminal law would be likely to adopt had the case occurred in Canada. The thesis adopts a comparative, analytical approach that focuses on law reform: • comparative, because the question of whether German criminal law does lack respect for the realities of life will be examined by comparing German legal reasoning with Anglo-Canadian legal reasoning. • analytical, because when exploring what German and Canadian law regarding "offences against personal freedom" is, the focus will be on familiar, formal techniques of legal reasoning, such as those which draw on legislative texts, legislative history, underlying principles, academic commentary, fundamental values in the constitution, and theoretical concerns. • law reform, because the question is explored of whether German criminal law can learn from Canadian criminal law how to be more open to taking varying social locations of people affected by criminal law into account. In particular it is asked whether one can reconcile the traditional German conceptual approach that promises certainty of the law and the Canadian contextual approach that is better able to be attentive to equality as a fundamental right. It will be argued that such a reconciliation of approaches is possible and consists in a method that might be called egalitarian conceptualism. This approach unites the advantages of conceptual, abstract legal reasoning with the advantages of contextual thinking by merging equality as a fundamental concept with the existing conceptual framework of criminal liability. The principle "in dubio pro aequalitate" will be added to the principle "in dubio pro libertate".

description: The constant phase element (CPE) with a frequency-independent negative phase between current and voltage is used extensively in e.g. the bioimpedance and electrochemistry fields. Its physical meaning is only partially understood. Here we show that the responses of both the common capacitive CPE as well as the inductive CPE are exactly the same as those of simple RL and RC circuits where the inductor's or capacitor's value increases linearly with time. The resulting step and impulse responses are found and verified by simulation with the Micro-Cap simulation program. The realization with time-varying components correlates with known time-varying properties in applications.

Quantum Mechanics in Non-Inertial Frames with a Multi-Temporal Quantization Scheme: II) Non-Relativistic Particles

description: The non-relativistic version of the multi-temporal quantization scheme of relativistic particles in a family of non-inertial frames (see hep-th/0502194) is defined. At the classical level the description of a family of non-rigid non-inertial frames, containing the standard rigidly linear accelereted and rotating ones, is given in the framework of parametrized Galilei theories. Then the multi-temporal quantization, in which the gauge variables, describing the non-inertial effects, are not quantized but considered as c-number generalized times, is applied to non relativistic particles. It is shown that with a suitable ordering there is unitary evolution in all times and that, after the separation of center of mass, it is still possible to identify the inertial bound states. The few existing results of quantization in rigid non-inertial frames are recovered as special cases.

description: In 1932 the Herefordshire Regiment Old Comrades' Association published a booklet containing a copy of the Roll of Honour held in Hereford Cathedral. The copy from which these images are taken belonged to Emlyn James, who served with the regiment from 1914 to 1919. As NCO he often had to reply to enquiries from the wives and mothers of men who had died, and he said that writing letters which would give them comfort and minimise the horrors was one of the hardest things he had to do.

description: The Gutzwiller-projected mean field theory, also called Plain Vanilla or RMFT, is explained and its successes and possible extensions in describing the phenomenology of the cuprate superconductors are discussed. Throughout we emphasize that while this is a Hartree-Fock-BCS based theory, it embodies fundamental differences from conventional perturbative many-body theory which may be characterized by calling it a theory of the doped Mott insulator.

description: Lithium rich stars in globular clusters are rare. In fact, only 14 have been found so far, in different evolutionary phases from dwarfs to giants. Different mechanisms have been proposed to explain this enhancement, but it is still an open problem. Using spectra collected within the Gaia-ESO Survey, obtained with the GIRAFFE spectrograph at the ESO Very Large Telescope, we present the discovery of the first Li-rich star in the cluster NGC 1261, the second star known in the red giant branch bump phase. The star shows an extreme Li overabundance of A(Li)_LTE=3.92\pm0.14, corresponding to A(Li)_NLTE=3.40 dex. We propose that the Li enhancement is caused by fresh Li production through an extra mixing process (sometimes referred to as {\em cool bottom burning}) or could be a pre-existing Li overabundance resulting from binary mass transfer, likely from a red giant branch star, because of the low barium abundance. To unambiguously explain the Li enhancement in globular cluster stars, however, a reliable determination of the abundance of key species like Be, 6Li, 12C/13C, and several s-process elements is required, as well as detailed modeling of chromospheric activity indicators.
