description: This work focuses on the definition and study of the n-dimensional k-vector, an algorithm devised to perform orthogonal range searching in static databases with multiple dimensions. The methodology first finds the order in which to search the dimensions, and then, performs the search using a modified projection method. In order to determine the dimension order, the algorithm uses the k-vector, a range searching technique for one dimension that identifies the number of elements contained in the searching range. Then, using this information, the algorithm predicts and selects the best approach to deal with each dimension. The algorithm has a worst case complexity of $\mathcal{O}(nd(k/n)^{2/d})$, where $k$ is the number of elements retrieved, $n$ is the number of elements in the database, and $d$ is the number of dimensions of the database. This work includes a detailed description of the methodology as well as a study of the algorithm performance.

description: This paper introduces and applies an analytical framework to study how formal and informal institutions influence socio–economic change and poverty reduction in rural Cambodia, giving specific reference to property rights and collective action. It focuses on emerging endogenous mechanisms of cooperation as well as on the role of external actors and instruments in forming or enhancing collective action institutions, and enforcing use and ownership rights among the rural poor. Within this framework key contextual factor, such as asset endowments, legal structures, and power relations, have an impact on poverty and rural livelihoods, but are also mediated and changed by property right regimes and local cooperation. Findings indicate that access to and use of natural capital still contributes significantly to rural incomes. Access to natural resources is, however, defined by multiple and overlapping rights, both private and common ones, which are, in turn, governed by formal and informal patterns of cooperation. Collective action also contributes to improve livelihoods. Nevertheless, depending on asset endowments, differences exist in the degree of participation. Owing to Cambodia’s recent history of genocide, forced collectivization and resettlement, property rights regimes have been severely affected, remain contested, and are re–established only slowly. In this context, the mutual trust necessary for successful cooperation in common property issues is severely undermined.

description: We demonstrate that even under positive partial transpose preserving operations in an asymptotic setting GHZ and W states are not reversibly interconvertible. We investigate the structure of minimal reversible entanglement generating set (MREGS) for tri-partite states under positive partial transpose (ppt) preserving operations. We demonstrate that the set consisting of W and EPR states alone cannot be an MREGS. In this context we prove the surprising result that the relative entropy of entanglement can be strictly sub-additive for certain pure tri-partite states which is crucial to keep open the possibility that the set of GHZ-state and EPR states together constitute an MREGS under ppt-preserving operations.

description: This study presents an approach to analyzing decentralized forestry and natural resource management and land property rights issues, and catalyzing collective action among villages and district governments. It focuses on understanding the current policies governing local people’s access to property rights and decision making processes, and learning how collective action among community groups and interaction among stakeholders can enhance local people’s rights over lands, resources, and policy processes for development. The authors applied participatory action research in two villages, one each in the Bungo and Tanjabbar districts of Jambi province (Sumatra), Indonesia, to facilitate identification of priorities through phases of planning, action, monitoring, and reflecting. This study finds that action research may be an effective strategy for fostering collective action and maintaining the learning process that leads groups to be more organized and cohesive, and district government officials to be more receptive to stakeholders. A higher level of collective action and support may be needed to avoid elite capture more effectively.

description: Identifying quantum phases and phase transitions is key to understand complex phenomena in statistical physics. In this work, we propose an unconventional strategy to access quantum phases and phase transitions by visualization based on the distribution of ground states in Hilbert space. By mapping the quantum states in Hilbert space onto a two-dimensional feature space using an unsupervised machine learning method, distinct phases can be directly specified and quantum phase transitions can be well identified. Our proposal is benchmarked on gapped, critical, and topological phases in several strongly correlated spin systems. As this proposal directly learns quantum phases and phase transitions from the distributions of the quantum states, it does not require priori knowledge of order parameters of physical systems, which thus indicates a perceptual route to identify quantum phases and phase transitions particularly in complex systems by visualization through learning.

description: We propose a simple way of evaluating the bulk spin generation of an arbitrary crystal with a known band structure in the strong spin-orbit coupling limit. We show that, in the presence of an electric field, there exists an intrinsic torque term which gives rise to a nonzero spin generation rate. Using methods similar to those of recent experiments which measure spin polarization in semiconductors, this spin generation rate should be experimentally observable. The wide applicability of this effect is emphasized by explicit consideration of a range of examples: bulk wurtzite and strained zincblende (n-GaAs) lattices, as well as quantum well heterojunction systems.

description: This paper discusses the effects of markets restructuring on small-scale farmers in South Africa by analysing the determinants of small-scale farmers’ market choices in the tomato sector in two Provinces. South Africa has a very dualistic agricultural sector with a highly performing large-scale capital intensive agriculture on one hand and a traditional, semi subsistence small-scale communal sector on the other. Small farmers’ participation in modern markets (i.e. supermarkets, agro-processors and national fresh produce markets) is thus very low. Furthermore, results from our survey indicate that small-scale tomato growers in Limpopo and Mpumalanga provinces prefer supplying informal markets than modern markets. The econometric analysis of household level data indicates that access to land is a key determinant of their participation in modern markets. As confirmed by our survey, small-scale farming systems in South Africa are still very poorly capitalised. While still not being widely used, the key non-land asset variable is whether they can produce under greenhouses, thus supplying consistent quality demanded by the modern local channels. Other factors such as education and location in a good tomato producing area are also significant determinants of participation in modern markets. Interestingly, ownership of a cell phone as well as the number of market channels to which the farmers are connected are significant in determining market choices but they are negatively related to modern markets choice, which is to be related to the different natures of the transactions. Modern markets propose fixed prices or at least very stable prices under some forms of contractual arrangements while informal markets offer relatively flexible prices, price discovery and price risk management (through multiple marketing strategies) thus being much more important. The econometric analysis also shows that supplying modern markets does not improve small-scale farmers’ income whereas the access to a cell phone does, which supports the importance of the cell phone in price management as well as the preference for informal markets.

description: Tomb towers rank second (only lagging behind mosques) in Iran based on the number of the remaining constructs, playing a multifaceted role in the architecture of this country. Thus, exploring the different aspects of their origin, emergence and development is of paramount importance and leads to a deeper understanding of the Iranian architecture regarding the construction of tombs. The present study aimed at investigating tomb towers in Samiran and Kharaqan districts from historical, geographical, architectural and geometrical perspectives by means of studying their commonalities and distinctions. In so doing, the authors applied library and field study research to comparatively examine Samiran and Kharaqan tomb towers. Based on the data gathered and through the reanalysis and identification of Iranian-Islamic arches, they managed to digitally reconstruct the towers, concluding that both towers enjoyed common historical- ethnic roots with similar structures and geometrical golden ratios. In addition, historical and geographical investigations of the developmental trend in Kharaqan towers revealed that their design was generally influenced by the design, plans, forms and proportions of Samiran towers.

description: X-ray binaries exhibit a wide range of properties but there are few accepted methods to determine the nature of the compact object. Color-Color-Intensity diagrams have been suggested as a means of distinguishing between systems containing black holes from those containing neutron stars. However, this technique has been verified with data from only one instrument (RXTE/ASM) with a single set of X-ray colors defined using data available only in pre-determined energy bands. We test a selection of X-ray colors with a more sensitive instrument to determine the reliability of this method. We use data from the MAXI Gas Slit Camera, which allows users to specify energy-bands. We test X-ray colors that have been previously defined in the literature as well as ones that we define specifically in this paper. A representative set of systems are used to construct Color-Color-Intensity diagrams in each set of colors to determine which are best for separating different classes. For studying individual sources certain bands are more effective than others. For a specified energy range, the separation of soft states in black hole binaries was possible only where both soft and hard colors included information from the lowest energy band. We confirm that Color-Color-Intensity diagrams can distinguish between systems containing black holes or neutron stars in all X-ray colors tested; this suggests an universality in the accretion processes governing these different classes. We suggest possible physical processes driving different classes of X-ray binaries to different locations in Color-Color-Intensity diagrams.

description: Supply chain restructuring and its impact on farmers’ situation have become the subject of vast interest among agricultural economists. However, there have been relatively few studies trying to quantitatively asses this issue. This paper analyses the impact of supply chain modernisation on dairy farmers in Poland. It is shown that joining the modern marketing channel positively affects farmers’ incomes. The decision to enter the modern channel is crucially dependent on access to funds and facilitated by having larger cow herds.

description: The objective of this research is to evaluate a land value tax as a potential policy tool to moderate sprawling development in Nashville, TN, the nation’s most sprawling metropolitan community with a population of one million or more. To achieve this objective, the hypothesis is empirically tested that a land value tax encourages more development closer to preexisting development than farther from preexisting development. Specifically, the marginal effects of a land value tax on the probability of land development is hypothesized to be greater in areas around preexisting development than in areas more distant from preexisting development. The findings show that the marginal effects of a land value tax on the probability of developing parcels that neighbored previously developed parcels was greater than the probability of developing parcels that did not neighbor previously developed parcels. This finding suggests that land value taxation could be used to design compact development strategies that address sprawling development.

description: We perform a study both statistical and theoretical for cosmological models of matter creation and their ability to describe effective phantom models of dark energy. Such models are beyond the $Λ$CDM model since the resulting cosmic expansion is not adiabatic. In fact, we show that this approach exhibits transient phantom/quintessence scenarios at present time and tends to the standard cosmological model at some stage of the cosmic evolution. We discuss some generalities of the thermodynamics properties for this type of cosmological model; we emphasize on the behavior of the temperature associated to dark matter, which keeps positive along cosmic evolution together with the entropy. The enrichment of this type of model by means of the incorporation of cosmological constant and dissipative effects in the fluid description to explore their cosmological consequences in the expansion of the universe is considered. Finally, a generalization for the matter production rate as an inhomogeneous expression of the Hubble parameter and its derivatives is discussed; as in all the cases examined, such election leads to an effective phantom/quintessence behavior.

description: The magic texture is one of the successful textures of the flavor neutrino mass matrix for the Majorana type neutrinos. The name "magic" is inspired by the nature of the magic square. We estimate the compatibility of the magic square with the Dirac, instead of the Majorana, flavor neutrino mass matrix. It turned out that some parts of the nature of the magic square are appeared approximately in the Dirac flavor neutrino mass matrix and the magic squares prefer the normal mass ordering rather than the inverted mass ordering for the Dirac neutrinos.

The technology and economics of water-borne transportation systems in Roman Britain
Creators: name: Millar, Roderick J. O.
Publisher: name: University of British Columbia
Year: 2009

description: The thesis examines a number of questions concerning the design, construction, costs and use of Romano-British seagoing and inland waters shipping. In the first part the reasons for the methods of construction for seagoing and coastal vessels, such as the Blackfriars Ship 1, the St. Peter Port Ship and the Barland's Farm Boat, have been investigated. The constructional characteristics of the two ships are massive floors and frames, with the planking fastened only to the floors and frames with heavy clenched iron nails. There is no edge to edge fastening of the planks, with tenons inserted into mortises cut into the edges of the planks, as is normal in the Mediterranean tradition of ship construction in the Roman period. The Romano-British ships also differ from the Scandinavian tradition of clinker building with overlapping planks nailed to each other along their length. It has been concluded that a natural phenomenon, the large tidal range around the British Isles and the northern coasts of Gaul and Germany, had a dominant effect on the design of seagoing vessels. Deep water harbours, such as Portus, Caesar ea Maritima and Alexandria in the Mediterranean, where ships could lie afloat at all times, were neither practicable nor economic with the technology available. At the British ports, such as Dover, London and Chichester, ships had to come in with the high tide, moor to simple wharves at the high tide level, and then settle on the ground as the tide dropped. At the numerous small havens, inlets and estuaries around the British coasts, ships would come in with the tide, settle on a natural or man-made 'hard' as the tide fell, and discharge cargo over the side to carts, pack animals or people. This mode of operation required sturdy ships that could take the ground without damage, and also withstand a certain amount of 'bumping' on the bottom in the transition period from fully afloat to fully aground. The second part of the thesis investigates the cost of building, maintaining and operating various types of vessels. To do this, a new mode for measuring cost, the Basic Economic Unit, or BEU, has been developed. The probable volume of the various types of cargoes carried has been examined. It appears that grain was the dominant cargo in both coastal and overseas traffic. The total cost of building, maintaining and operating the seagoing and inland water shipping was less than one percent of the gross product of Britain, a small cost for an essential service.

description: This work introduces two new techniques for random number generation with any prescribed nonlinear distribution based on the k-vector methodology. The first approach is based on inverse transform sampling using the optimal k-vector to generate the samples by inverting the cumulative distribution. The second approach generates samples by performing random searches in a pre-generated large database previously built by massive inversion of the prescribed nonlinear distribution using the k-vector. Both methods are shown suitable for massive generation of random samples. Examples are provided to clarify these methodologies.

description: As agriculture becomes more industrialized, the role of risk measures such as value-at-risk (VaR) will become more utilized. In this case it was applied to geographical diversification and also modifying the traditional VaR estimation by incorporating a copula dependence parameter into the VaR estimation. In addition, an alternative risk measure was also calculated, CVaR. The CVaR, unlike VaR, is a coherent risk measure. Thus it does not suffer from many of the shortcomings of the VaR. The land portfolio consisted of Dryland wheat production acres in Texas, Colorado, and Montana. Three series of net returns were calculated for each region. Based on the VaR and the CVaR, the portfolio was optimized based on minimizing the expected loss based on historical net revenues. The results showed that diversification could be reduced by producing in all three areas.
Self-esteem and wellbeing in deaf adults

description: The first section details a systematic literature review, which examined self-esteem among deaf adults. Fourteen studies were included within the review. Deaf participants were found to report lower levels of self-esteem than hearing participants. Deaf identity was also identified as having a significant association with self-esteem, with higher self-esteem associated with having a Deaf or bicultural identity. Further studies are now needed to examine what influence cochlear implants might have on this relationship, in addition to examining how the reading comprehension of participants might influence the accuracy of findings drawn from written self-report measures. Second, a research study was conducted exploring the relationship between wellbeing, adult attachment and emotion regulation. Whilst associations between these variables have been identified among hearing populations, less is known on the association between these factors in the context of deafness. Data was collected via an online survey from deaf adults in the general population, with 86 participants included within the final analysis. The relationships between the variables, which also included demographic variables, were explored using correlations and t-tests. Adult attachment anxiety, cognitive reappraisal and preferred language were all found to be significant predictors of wellbeing in the final regression models. The findings support previous research indicating that early attachment experiences may influence adult wellbeing, with reciprocal communication between deaf infants and their parents thought to play a key role in developing a secure attachment. The findings have important clinical implications for supporting the families of deaf infants as well as supporting deaf adults. The third section details a critical appraisal of the whole thesis. This section comprises a summary of the key findings of the literature review and research study, areas for future research and personal reflections on the process.

description: Since the early 1900s much research has been conducted on salary gaps between men and women in different professions. While some of that work has focused on agricultural economics professionals, little research could be found specifically relating to agricultural economic professionals in federal employment. A survey was sent to known agricultural economics professionals within USDA. The data from this survey are being used for two purposes. The first is to determine whether differences exist between men and women (and between employees in different agencies) in factors that influence job choice and potential problems in the workplace. The second is to identify factors that influence salaries of men and women agricultural economics professionals in federal employment. This paper addresses the first purpose.

description: Recent end-to-end Automatic Speech Recognition (ASR) systems demonstrated the ability to outperform conventional hybrid DNN/ HMM ASR. Aside from architectural improvements in those systems, those models grew in terms of depth, parameters and model capacity. However, these models also require more training data to achieve comparable performance. In this work, we combine freely available corpora for German speech recognition, including yet unlabeled speech data, to a big dataset of over $1700$h of speech data. For data preparation, we propose a two-stage approach that uses an ASR model pre-trained with Connectionist Temporal Classification (CTC) to boot-strap more training data from unsegmented or unlabeled training data. Utterances are then extracted from label probabilities obtained from the network trained with CTC to determine segment alignments. With this training data, we trained a hybrid CTC/attention Transformer model that achieves $12.8\%$ WER on the Tuda-DE test set, surpassing the previous baseline of $14.4\%$ of conventional hybrid DNN/HMM ASR.

description: The powder aerosol deposition (PAD) method is a well-known process to fabricate dense layers at room temperature directly from the powder. It is particularly suitable for the deposition of ceramic materials. Compared to these, the use of metal powders (here iron), which are significantly more ductile and have a higher density than typical ceramic powders, has not yet been investigated in detail for PAD. In the first step of this work, the iron powder is characterized by scanning electron microscopy and x-ray diffraction. In order to improve the deposition behavior, the influence of heat treatment on the crystallite and the particle size of the iron powder is investigated. It is shown that the crystallite size of iron powders is reduced down to a nanocrystalline size during deposition. The magnetic properties of the iron powder as well as the layers are investigated by means of coercive field development. Although the initial coercivity raises after deposition, potential applications for flux guiding in microelectronic sensors and devices are feasible. In the second step, thin metal layers (iron) and ceramics (aluminum oxide) are deposited alternatingly to produce iron–alumina multilayer structures.
The tachocline revisited

description: The solar tachocline is a shear layer located at the base of the solar convection zone. The horizontal shear in the tachocline is likely turbulent, and it is often assumed that this turbulence would be strongly anisotropic as a result of the local stratification. What role this turbulence plays in the tachocline dynamics, however, remains to be determined. In particular, it is not clear whether it would result in a turbulent eddy diffusivity, or anti-diffusivity, or something else entirely. In this paper, we present the first direct numerical simulations of turbulence in horizontal shear flows at low Prandtl number, in an idealized model that ignores rotation and magnetic fields. We find that several regimes exist, depending on the relative importance of the stratification, viscosity and thermal diffusivity. Our results suggest that the tachocline is in the stratified turbulence regime, which has very specific properties controlled by a balance between buoyancy, inertia, and thermal diffusion.

 Material examined. Syntype, male: Colombie [NHMW]. Other material as previously reported (Jordal 1998 b, 2013, 2018).
 This species is very similar to several of the new species described in this paper and a brief note with illustrations is therefore needed to avoid confusion. Scolytodes chapuisi is characterised by uniseriate interstriae, by shallow, fine and widely spaced pronotal punctures, and a shiny median third in the female frons with a long tuft of setae. The female frons is similar in S. inordinatus, but the latter species has strongly confused interstrial punctures, particularly on the posterior half of elytra, and is distinctly different at multiple genetic markers. S. chapuisi and S. cancellatus have both more regular rows of punctures in each interstriae, but S. chapuisi differs by the much smaller elytral and pronotal punctures.
