description: Agriculture forms the foundation of Kenya’s economy. However, the information base on agriculture % including basic indicators on farmers’ input, production, and marketing behavior, household food consumption patterns, etc. % is weak and largely outdated. Agricultural policy is largely made on the basis of conventional wisdom about the way things work. In a dynamic, evolving economy, long-standing perceptions may become increasingly inconsistent with current reality, particularly when the system has been exposed to dramatic changes such as structural adjustment, market liberalization, and the advent of new technology. In such a setting, entrenched perceptions about the way farmers, traders and consumers actually behave may lead to unintended and even counterproductive government policy. This paper aims to demonstrate how monitoring the rural economy through timely, periodic and reasonably representative household surveys can inform debate on existing and emerging policy issues.

description: We analyse a recent generalised free-energy for liquid crystals posited by Virga and falling in the class of quartic functionals in the spatial gradients of the nematic director. We review some known interesting solutions, i. e., uniform heliconical structures, and we find new liquid crystal configurations, which closely resemble some novel, experimentally detected, structures called Skyrmion tubes. These new configurations are characterised by a localised pattern given by the variation of the conical angle. We study the equilibrium differential equations and find numerical solutions and analytical approximations.

description: We present a variational solution of the T-matrix integral equation within a local approximation. This solution provides a simple form for the T matrix similar to Hubbard models but with the local interaction depending on momentum and frequency. By examining the ladder diagrams for irreducible polarizability, a connection between this interaction and the local-field factor is established. Based on the obtained solution, a form for the T-matrix contribution to the electron self-energy in addition to the GW term is proposed. In the case of the electron-hole multiple scattering, this form allows one to avoid double counting.

description: Solar prominences are formed by partially ionized plasma with inter-particle collision frequencies generally warranting magnetohydrodynamic treatment. In this work, we explore the dynamical impacts and observable signatures of two-fluid effects in the parameter regimes when ion-neutral collisions do not fully couple the neutral and charged fluids. We perform 2.5D two-fluid (charges - neutrals) simulations of the Rayleigh-Taylor instability (RTI) at a smoothly changing interface between a solar prominence thread and the corona. The purpose of this study is to deepen our understanding of the RTI and the effects of the partial ionization on the development of RTI using non-linear two-fluid numerical simulations. Our two-fluid model takes into account viscosity, thermal conductivity, and collisional interaction between neutrals and charges: ionization/recombination, energy and momentum transfer, and frictional heating. In this paper I, the sensitivity of the RTI dynamics to the prominence equilibrium configuration, including the impact of the magnetic field strength and shear supporting the prominence thread, and the amount of prominence mass-loading is explored. We show that, at small scales, a realistically smooth prominence-corona interface leads to qualitatively different linear RTI evolution than that expected for a discontinuous interface, while magnetic field shear has the stabilizing effect of reducing the growth rate or eliminating the instability. In the non-linear phase, we observe that in the presence of field shear the development of the instability leads to formation of coherent and interacting 2.5D magnetic structures, which, in turn, can lead to substantial plasma flow across magnetic field lines and associated decoupling of the fluid velocities of charges and neutrals.
The effect of disrupting the human magnocellular pathway on global motion perception
Creators: name: Hoag, Ryan Alexander
Publisher: name: University of British Columbia
Year: 2009

description: Purpose: To determine the effect of human magnocellular (M) pathway disruption on global motion perception. Method: Thirty adults completed a global motion task under four conditions. The task was completed after adaptation to full-field sinusoidal flicker (experimental condition #1), after adaptation to a gray field (control condition #1), in the presence of a red background (experimental condition #2) and in the presence of a gray background (control condition #2). Based on lesion studies and the physiological properties of single cells in the subcortical M pathway, it was predicted that the psychophysical techniques use in both experimental conditions would disrupt normal functioning of this pathway and result in elevated motion coherence thresholds. Results: Adaptation to flicker and the presence of a red background increased motion coherence thresholds. The threshold elevation was greater when participants were adapted to flicker. Conclusion: Flicker adaptation and the presence of a red background are assumed to temporarily disrupt the M pathway at a subcortical level. The fact that these techniques elevate motion coherence thresholds suggests that the subcortical M pathway is needed for normal human motion perception.

Low-temperature critical current of Y1-xCaxBa2Cu3O7-delta thin films as a function of hole content and oxygen deficiency

description: The effects of hole content (p) and oxygen deficiency (delta) on the zero-field critical current density, Jc0, were investigated for high-quality c-axis oriented Y1-xCaxBa2Cu3O7-delta (x = 0, 0.05, 0.10, and 0.20) thin films. Ca was used to introduce hole carriers in the CuO2 planes, independent of the oxygen deficiency in the CuO1-delta chains. Low-temperature Jc0(16K) of these films above the optimum doping were found to be high (> 10^7 Amp/cm^2) and were primarily determined by the hole concentration, reaching a maximum at p ~ 0.185+/-0.005, irrespective of oxygen deficiency. This implies that oxygen disorder plays only a secondary role and the intrinsic Jc0 is mainly governed by the carrier concentration and consequently by the superconducting condensation energy which also peaks at p ~ 0.19 where the pseudogap correlation vanishes.

description: The 2005 – 2006 marketing campaign was difficult because of the drought that occurred in all countries in the region. As a result, the price of sorghum, millet, maize and rice soared. State actions to improve cereals supply through tax-exempt rice imports did not achieve the expected outcomes. Rice has been the main contributing factor to the rise of cereals price. The low levels of stocks of rice in the world and the supply in fertilizers below expectations along with a decrease in productivity have contributed to the rise of rice prices at the national level.

description: Recognizing that science and technology research (S&T) is one of many inputs into the broader development process, USAID/Mali, via its Initiative to End Hunger in Africa, requested an assessment of the current S&T situation in Mali. USAID asked the assessment team to produce a comprehensive strategic options plan for a Malian S&T agenda that would identify priority short-term actions to stimulate uptake of S&T results likely to make significant contributions to the attainment of Mali’s broad development goals, while simultaneously developing a coherent longer-term action plan to maintain and improve the human, physical, and financial capital needed to generate future streams of S&T results. The scope of work for the assessment team included six points: • Review the current status of agricultural and natural resource programs of Mali’s research institutions, with particular attention to IER, IPR/IFRA, LCV; • Review and assess the programs of International Agriculture Research Centers (IARCs) and other international foundations supporting research in Mali; • Annotate the range of USAID-supported S&T programs in Mali; • Identify available production technology packages and needed support services to achieve rapid (medium-term) impact and identify gaps in S&T programs that hinder attainment of GRM development goals; • Develop a strategic options plan to build needed S&T capabilities, including those for research and supporting institutional development; • Make recommendations for potential USAID/Mali actions, including building partnerships with public and private organizations that would enhance the effective use of S&T for achieving USAID programmatic goals

description: In this paper we presented a lot of experiments that examine how the particular parts of the documents do contribute to the performance of a classifier. We evaluated text classifiers on two very different text corpora. We conclude that some parts of the text are more important from the point of text classification performance. Giving higher weights to more important parts can increase the performance of the classifier. The question, that which parts are more or less important depends on the nature of the documents in the corpora. Some tasks that remains to be done: − More text corpora should be investigated. − In section 6.4 we optimized the number of features to be kept independent from the section. However, it could be optimized for each section. − Splitting the documents into parts of 50 words, to examine what if the parts are of equal size not only inside a document, but among the documents too. − When splitting documents into k equal parts, we may combine the classifiers resulted from different k values.

description: Applying modelling techniques for getting acquainted with customer behaviour, predicting the customers’ next step is neccessary to keep in competition, by decreasing the capital requirement (Basel II - IRB) or making the portfolio more profitable. According to the easily implementable modelling techniques, data mining solutions widespread in practice. Using these models with no conditions can lead into inconsistent future on portfolio change. Consequence of this situation, contradictory predictions and conclusions come into existence. Recognizing and conscious handling of inconsistent predictions is an important task for experts working on different scene of the knowledge based economy and society. By realizing and solving the problem of inconsistency in modelling processes, the competitive advantage can be increased and strategic decisions can be supported by consistent predictions.

POSSIBILITIES FOR REDUCING HEALTH RISKS IN FOOD RETAIL

description: Managers of organic food stores – as regarding the influence on health – see reliable origin to be the most important criterion during their product selecting decision making process. In the case of traditional foods they find additive artificial materials and GMOs significant among health risks, in the case of organic foods they think that significant problems arise from the shortness of the "best before” period. Dangers coming from the market orientation are judged to be more serious in the case of traditional foods than in the case of organic foods. It is in connection with the mentality with that during their product selecting decision making they emphasize factors connected to safety (eg.: reliable origin) more than market considerations (eg.: fast circulation or it is included in the choice of the competitors). Healthy foods are expected to have a reliable origin, too. In connection with the reliable origin of the products I could throw light on the contradiction that they regard the reliability of producers and sellers important, at the same time the place of origin has little influence on how safe they regard a particular product. 50% of the shopmanagers looking for products with a reliable origin judge Hungarian foods to be safe, 19% of them judge import, 34% of them judge regional products to be safe. Based on these results I find it needed to make a research that gives the possibility to examine the profiles of differentiated products based on their places of origin, in respect of thier influence on health and their risk factors. In the case of imported products it would be crucial to make difference between products coming from more and coming from less developed countries than our country. In the case of organic foods it is especially reasonable because the major part of their choice is products from abroad, that come from West-Europe (mostly from Germany and Austria), but more and more cheaper eastern organic foods appear in their portfolio (eg.: Romanian). During checking the hypothesis it could be seen that the risks of food safety were sensed in the whole process of production by shop managers. But with their behaviour to reduce risk factors they want to filter the factors of inner ingredients (eg.: artificial additives, GMOs) that directly endanger health, and they do not pay attention to indirect sources of danger (eg.: place of origin). For this reason I think it is needed to analyze the supply chain of organic foods getting into the market from the point of view of safety, so that not only risks coming from inner ingredients are supported. This would provide a starting point for the managers of organic food stores to minimalize the whole circle of risk factors.
One-Dimensional Directed Sandpile Models and the Area under a Brownian Curve

description: We derive the steady state properties of a general directed ``sandpile'' model in one dimension. Using a central limit theorem for dependent random variables we find the precise conditions for the model to belong to the universality class of the Totally Asymmetric Oslo model, thereby identifying a large universality class of directed sandpiles. We map the avalanche size to the area under a Brownian curve with an absorbing boundary at the origin, motivating us to solve this Brownian curve problem. Thus, we are able to determine the moment generating function for the avalanche-size probability in this universality class, explicitly calculating amplitudes of the leading order terms.

The lower transverse critical field as well as the critical field and the critical current of the first vortex nucleation at the superconductor/magnet interface are calculated on the basis of an exact solution for a vortex of arbitrary plane configuration. The Bean-Livingston barrier against the vortex nucleation is shown to strongly depend on the magnet sheath parameters.

description: We explore the adiabatic pulsational properties of massive white dwarf stars with hydrogen-rich envelopes and oxygen/neon and carbon/oxygen cores. To this end, we compute the cooling of massive white dwarf models for both core compositions taking into account the evolutionary history of the progenitor stars and the chemical evolution caused by time-dependent element diffusion. In particular, for the oxygen/neon models, we adopt the chemical profile resulting from repeated carbon-burning shell flashes expected in very massive white dwarf progenitors. For carbon/oxygen white dwarfs we consider the chemical profiles resulting from phase separation upon crystallization. For both compositions we also take into account the effects of crystallization on the oscillation eigenmodes. We find that the pulsational properties of oxygen/neon white dwarfs are notably different from those made of carbon/oxygen, thus making asteroseismological techniques a promising way to distinguish between both types of stars and, hence, to obtain valuable information about their progenitors.

description: We present an update of our on-going project to characterise the impact of radio jets on the ISM by tracing molecular gas at high spatial resolution using ALMA. The radio active galactic nuclei (AGN) studied show recently born radio jets. In this stage, the plasma jets can have the largest impact on the ISM, as also predicted by state-of-the-art simulations. The two targets have quite different ages, allowing us to get snapshots of the effects of radio jets as they grow. Interestingly, both also host powerful quasar emission. The largest mass outflow rate of molecular gas is found in a radio galaxy hosting a newly born radio jet emerging from an obscuring cocoon of gas and dust. Although the mass outflow rate is high (few hundred Msun/yr), the outflow is limited to the inner few hundred pc region. In a second object, the jet is larger (a few kpc) and is in a more advanced evolutionary phase. In this object, the distribution of the molecular gas is reminiscent of what is seen, on larger scales, in cool-core clusters hosting radio galaxies. Gas deviating from quiescent kinematics is not very prominent, limited only to the very inner region, and has a low mass outflow rate. Instead, on kpc scales, the radio lobes appear associated with depressions in the distribution of the molecular gas, suggesting they have broken out from the dense nuclear region. The AGN does not appear to be able at present to stop the star formation observed in this galaxy. These results suggest that the effects of the radio source start in the first phases by producing outflows which, however, tend to be limited to the kpc region. After that, the effects turn into producing large-scale bubbles which could, in the long term, prevent the surrounding gas from cooling. Our results characterise the effect of radio jets in different phases of their evolution, bridging the studies done for radio galaxies in clusters.

description: Operator square-roots are ubiquitous in theoretical physics. They appear, for example, in the Holstein-Primakoff representation of spin operators and in the Klein-Gordon equation. Often the use of a perturbative expansion is the only recourse when dealing with them. In this work we show that under certain conditions differential equations can be derived which can be used to find perturbatively inaccessible approximations to operator square-roots. Specifically, for the number operator $\hat n=\hat a^†a$ we show that the square-root $\sqrt{\hat n}$ near $\hat n=0$ can be approximated by a polynomial in $\hat n$. This result is unexpected because a Taylor expansion fails. A polynomial expression in $\hat n$ is possible because $\hat n$ is an operator, and its constituents $a$ and $a^†$ have a non-trivial commutator $[a,a^†]=1$ and do not behave as scalars. We apply our approach to the zero mass Klein-Gordon Hamiltonian in a constant magnetic field, and as a main application, the Holstein-Primakoff representation of spin operators, where we are able to find new expressions that are polynomial in bosonic operators. We prove that these new expressions exactly reproduce spin operators. Our expressions are manifestly Hermitian, which offer an advantage over other methods, such as the Dyson-Maleev representation.

description: We analyze the behavior of systems of two and three qubits made by Josephson junctions, treated in the two level approximation, driven by a radiation mode in a cavity. The regime we consider is a strong coupling one recently experimentally reached for a single junction. Rabi oscillations are obtained with the frequency proportional to integer order Bessel functions in the limit of a large photon number, similarly to the case of the single qubit. A selection rule is derived for the appearance of Rabi oscillations. A quantum amplifier built with a large number of Josephson junctions in a cavity in the strong coupling regime is also described.

description: Pharmaceutical industry belongs to the most innovative branches in Hungary. However as a consequence of increasing development costs and the strong competition on the market the means of gaining competitive advantage has become a focal point of the pharmaceutical companies’ strategy. Economic performance is highly dependent on research and knowledge and economic success is determined how companies are able to apply this knowledge and skills so how flourishing the product or technological development becomes. Only those branches and companies will gain competitive advantage that are able to compete on knowledge and technology. Since science and technology are considered to be the most important source of economic development, it contributes to the more effective restructuring and increased productivity.

description: The theory of transport phenomena in multicomponent electrolyte solutions is presented here through the integration of continuum mechanics, electromagnetism, and non-equilibrium thermodynamics. The governing equations of irreversible thermodynamics, including balance laws, Maxwell's equations, internal entropy production, and linear laws relating the thermodynamic forces and fluxes, are derived. Green-Kubo relations for the transport coefficients connecting electrochemical potential gradients and diffusive fluxes are obtained in terms of the flux-flux time correlations. The relationship between the derived transport coefficients and those of the Stefan-Maxwell and infinitely dilute frameworks are presented, and the connection between the transport matrix and experimentally measurable quantities is described. To exemplify application of the derived Green-Kubo relations in molecular simulations, the matrix of transport coefficients for lithium and chloride ions in dimethyl sulfoxide is computed using classical molecular dynamics and compared with experimental measurements.

description: The environmental quality is recognized to be an important factor while making decisions upon the destination to visit. The image of the resort will likely to be more realistic but also complex after the tourists’ visit. The complex image of the resort, where the tourist has about after visiting it, is crucial for creating loyalty and also word of mouth advertising. Therefore, if the tourists visiting the resort are to complain then the intermediaries will likely to reduce the tourism activities through that resort or the tourism activities will turn into a more hotel facility based activity. Resort planning is a continous process and defines the systemized and controlled development of the resort. Resort planning can be implemented in an actual resort or a new developing resort. The increasing importance of sustain-ability in the tourism industry emerged the need for resort planning. It’s important to emphasize that planning needs to be upgraded through the environmental and market changes. As it is a continous process the factors included in must be strict in the short run and flexible in the long run due to the changes. Resorts, generally subject to seasonal tourism activities, should have a positive image through many aspects in order to attract tourists and try to sustain it by the time. Resort planning is essential in order to shape the future and the image of the resort destination. In addition the satisfaction of the tourist will be retained if the tourist believes that they are getting high value from the destination considering their travel expenses. It is the destination image that will determine the future of the destination. Because the resort experience is intangible the competition among the resort destinations is determined by the image of each resort.

description: Phishing is a social engineering tactic primarily designed to acquire personal or private information, potentially causing damage to the targeted individual or organisation in many ways. Consequently, there is an imperative need for precise phishing detection. This project aims to create an efficient and dependable system for an early identification or classification of emails as phishing or benign, using two datasets from the Nazario Fraudulent Corpus and the Apache SpamAssassin website, including 4,600 phishing and benign emails. A classification framework is constructed using several ML models, including DT, SVM, multilayer perceptrons (MLP), and LSTM. The data has been divided into an 80:20 ratio for training and testing these models. The performance of these models was evaluated in the present study using classification metrics such as accuracy, recall, precision, and F1-score. A comparison analysis reveals that LSTM models surpass others, attaining the best recall(98.56%), accuracy(98.89%), precision(98.87%), and F1-score(98.87%), while decision tree, SVM, and MLP recorded lower accuracy rates of 98.06%, 96.90%, and 98.90%, respectively. These conclusions show how beneficial ML approaches are in improving abilities to distinguish between genuine and phishing URLs.
Ethics in documentary filmmaking : an anthropological perspective
Creators: name: Hartzell, Lea Claire
Publisher: name: University of British Columbia
Year: 2009

description: Making a documentary film that features human beings as subjects requires extensive thought about the potential impact on the actual lives of people. Similarly, the pursuit of anthropological knowledge via social science research also affects individuals and communities. Along with this awesome power that documentary filmmaking and anthropological research have to change peoples' lives, comes a heavy responsibility to use this power in an ethical way. By examining the cross-sections between documentary filmmaking and anthropological research, I have found several intersections of ethical considerations that seem pertinent to both fields. The main ethical considerations I have found to be common to both documentary filmmaking and anthropology can be classified into four major categories. They are (1) the intention of the filmmaker/researcher, (2) the filmmaker/researcher's relationship with her subjects, (3) the various responsibilities of the filmmaker/researcher, and (4) how the filmmaker/researcher presents herself, her work, and the subjects to an audience. In the first part of this thesis, I provide a review of some of the recent literature from anthropology and visual communication to establish a theoretical background based in visual anthropology. In the second part, I apply the discussed theoretical concerns to practical examples of ethical questions that specific documentary filmmakers have faced. The particular instances that I draw upon come from a recent public forum and panel debate on the topic of "Ethics in Documentary Filmmaking" held in Vancouver B.C. on March 26,2002, sponsored by the Canadian Independent Film Caucus (CIFC). The three filmmakers from the panel that I discuss are Nettie Wild, Mark Achbar, and David Paperny. In the name of reflexivity, I also include a short discussion of some ethical concerns relating to my own documentary videos. I conclude this thesis with a summary discussion of ethics in documentary filmmaking. Perhaps as long as a filmmaker or researcher thinks about the ethics of her actions while she is carrying out her project, she is acting in an ethical way. Thoughtfulness and reflection bring about conscious actions, whereas the act of following strict guidelines often leads to robotic, mindless behaviour. Ultimately, it is the filmmaker who must consider each ethical issue individually and make decisions based on the specific circumstances of her project.
CORPORATE INTERNALIZATION OF SUSTAINABILITY REQUIREMENTS

description: Sustainability has become the boiling point of theoretical business discussions. At first it was only a concept everybody was talking about but no one knew how it should be materialized. Now we can understand how and why companies are inclined to follow the principle. This gives the policy makers and other stakeholders the tools to alter market conditions in ways that more and more companies accept the requirements of sustainability. Several levels of sustain-ability have been identified and now the discussion is shifting towards achieving a common ground how to measure sustainability. Since sustainability is such a broad concept and it is very dependant on the factors of the given industry the analyzed company is operating in, two major ways to measure the companies’ performance were identified: • One way, which is propagated by Barrett, is to look at the values the company internalized. • The other way is to try to define a commonly accepted framework of requirements and then apply this framework to measure the performance of the specific company. The future will tell which method will be embraced but my bet is on the one which offers clear-cut, easy-to-understand, and easy-to-implement solutions to companies.

description: We discuss the physics of a restricted Weyl symmetry in a curved space-time where a gauge parameter $Ω(x)$ of Weyl transformation satisfies a constraint $\Box Ω= 0$. First, we present a model of QED where we have a restricted gauge symmetry in the sense that a $U(1)$ gauge parameter $θ(x)$ obeys a similar constraint $\Box θ= 0$ in a flat Minkowski space-time. Next, it is precisely shown that a global scale symmetry must be spontaneously broken at the quantum level. Finally, we discuss the origin of the restricted Weyl symmetry and show that its symmetry can be derived from a full Weyl symmetry by taking a gauge condition $R = 0$ in the BRST formalism.
