description: Over the past decade, the policy and scholarly communities have increasingly recognized the need for governance of water-related issues at the global level. There has been major progress in the achievement of international goals related to the provision of basic water and some progress on sanitation services. However, the water challenge is much broader than securing supply. Doubts have been raised about the effectiveness of some of the existing governance processes, in the face of trends such as the unsustainable use of water resources, the increasing pressure imposed by climate change, or the implications of population growth for water use in food and energy production. Conflicts between different water uses and users are increasing, and the state of the aquatic environment is further declining. Inequity in access to basic water and sanitation services is still an issue. We argue that missing links in the trajectories of policy development are one major reason for the relative ineffectiveness of global water governance. To identify these critical links, a framework is used to examine how core governance processes are performed and linked. Special attention is given to the role of leadership, representativeness, legitimacy, and comprehensiveness, which we take to be critical characteristics of the processes that underpin effective trajectories of policy development and implementation. The relevance of the identified categories is illustrated with examples from three important policy arenas in global water governance: the effort to address access to water and sanitation, currently through the Millennium Development Goals; the controversy over large dams; and the links between climate change and water resources management. Exploratory analyses of successes and failures in each domain are used to identify implications and propose improvements for more effective and legitimate action.

description: We report mesoscopic dc current generation in an open chaotic quantum dot with ac excitation applied to one of the shape-defining gates. For excitation frequencies large compared to the inverse dwell time of electrons in the dot (i.e., GHz), we find mesoscopic fluctuations of induced current that are fully asymmetric in the applied perpendicular magnetic field, as predicted by recent theory. Conductance, measured simultaneously, is found to be symmetric in field. In the adiabatic (i.e., MHz) regime, in contrast, the induced current is always symmetric in field, suggesting its origin is mesoscopic rectification.

description: O artigo em questão tem por objetivo analisar um conjunto de fatores determinantes para a formação de renda das famílias rurais e seu nível de reprodução. Parte-se de uma pesquisa bibliográfica referente às indicações de estudos recentes que demonstram as transformações no espaço rural brasileiro, com a crescente diversificação das formas de ocupação das pessoas e alterações nas fontes de renda da família, tornando-as pluriativas. Diante desta nova dinâmica, resultante do aumento das ocupações não agrícolas, o foco de análise centrado na unidade de produção não mais contempla a necessidade de compreensão dos fenômenos atuais. Assim, as avaliações da reprodução social e econômica devem considerar a família como unidade de análise e suas inter-relações com a unidade de produção e o ambiente externo. Destaca-se que a renda familiar é resultado de diferentes formas de ocupações e atividades desenvolvidas pelos seus membros em decorrência de uma estratégia familiar definida a partir das relações estabelecidas no âmbito da unidade de produção, do mercado e do ambiente externo, que definem seu nível de reprodução. Trata-se de um esforço de proposição e síntese teórica que considera as inter-relações que ocorrem entre a família no âmbito rural e urbano, no intuito de explicar as diferentes origens da renda e sua estratégia de reprodução familiar. ----- This work analyzes a group of factors that are decisive to formation of rural families’ income and its reproduction level. Recent studies demonstrate that the transformations in the Brazilian rural space, with to growing diversification in the ways of people’s occupation and alterations in the sources of family income, turning them pluriactivity. This new dynamics given by the increase of the nonagricultural occupations has as consequences that the analysis focus centered in the farm not more contemplates the need of understanding of the current phenomena. Then, the family as unit of analysis and its inter-relations with the farm production and the external environment should be consider to the evaluations of the social and economic reproduction. It’s important to consider that the family income is resulted of different occupations forms and activities developed by their members as result to a family strategy defined from the established relations in the ambit of production, of market and of external environment that define its reproduction level. This study is an effort of theoretical proposition that considers the inter-relations that happens among the family in the rural and urban ambit, in the intention of explaining the different income origins and its strategy of family reproduction.

description: Cosmography becomes non-predictive when cosmic data span beyond the red shift limit $z\simeq1 $. This leads to a \emph{strong convergence issue} that jeopardizes its viability. In this work, we critically compare the two main solutions of the convergence problem, i.e. the $y$-parametrizations of the redshift and the alternatives to Taylor expansions based on Padé series. In particular, among several possibilities, we consider two widely adopted parametrizations, namely $y_1=1-a$ and $y_2=\arctan(a^{-1}-1)$, being $a$ the scale factor of the Universe. We find that the $y_2$-parametrization performs relatively better than the $y_1$-parametrization over the whole redshift domain. Even though $y_2$ overcomes the issues of $y_1$, we get that the most viable approximations of the luminosity distance $d_L(z)$ are given in terms of Padé approximations. In order to check this result by means of cosmic data, we analyze the Padé approximations up to the fifth order, and compare these series with the corresponding $y$-variables of the same orders. We investigate two distinct domains involving Monte Carlo analysis on the Pantheon Superovae Ia data, $H(z)$ and shift parameter measurements. We conclude that the (2,1) Padé approximation is statistically the optimal approach to explain low and high-redshift data, together with the fifth-order $y_2$-parametrization. At high redshifts, the (3,2) Padé approximation cannot be fully excluded, while the (2,2) Padé one is essentially ruled out.

description: We present a study of small carbon chains and rings in Photon Dominated Regions (PDRs) performed at millimetre wavelengths. Our sample consists of the Horsehead nebula (B33), the rho,Oph L1688 cloud interface, and the cometary-shaped cloud IC63. Using the IRAM 30-m telescope, the SEST and the Effelsberg 100-m teles cope at Effelsberg., we mapped the emission of \cch, c-C3H2 and C4H, and searched for heavy hydrocarbons such as c-C3H, l-C3H, l-C3H2, l-C4H2 and C6H. The large scale maps show that small hydrocarbons are present until the edge of all PDRs, which is surprising as they are expected to be easily destroyed by UV radiation. Their spatial distribution reasonably agrees with the aromatic emission mapped in mid-IR wavelength bands. Their abundances relative to H2 are relatively high and comparable to the ones derived in dark clouds such as L134N or TMC-1, known as efficient carbon factories. In particular, we report the first detection of C6H in a PDR. We have run steady-state PDR models using several gas-phase chemical networks (UMIST95 and the New Standard Model) and conclude that both networks fail in reproducing the high abundances of some of these hydrocarbons by an order of magnitude. The high abundance of hydrocarbons in the PDR may suggest that the photo-erosion of UV-irradiated large carbonaceous compounds could efficiently feed the ISM with small carbon clusters or molecules. This new production mechanism of carbon chains and rings could overcome their destruction by the UV radiation field. Dedicated theoretical and laboratory measurements are required in order to understand and implement these additional chemical routes.

description: A comercialização dos produtos agroextrativistas da agricultura familiar tem entrada em diferentes canais. Pretende-se com este estudo descrever o processo de venda da produção agroextrativista dos agricultores familiares do Rio dos Cochos. Busca analisar as efetividades e limitações à comercialização. A metodologia utilizada foi de cunho qualitativo, utilizando-se o estudo de multicasos, realizando a coleta de dados por meio de questionários semiestruturados, história oral e observação não participante. Observouse que a produção agroextrativista do Rio dos Cochos é escoada para mercados locais, regionais, nacionais, internacionais e institucionais. A comercialização da produção agroextrativista é pautada por relações que extrapolam as eminentemente mercantis: está associada à relação dos agricultores com os recursos naturais, à cultura e às formas organizacionais dessa população. O estudo conclui que as ações voltadas ao apoio à iniciativa da comercialização agroextrativista devem considerar esses aspectos, além dos econômicos. ----- The commercialization the family forming agro extractive production needs specific entry channels. The objective of this study is to describe the commercialization process of family farmers agro extractive products from the Rio dos Cochos region. It seeks to analyze the effectiveness and limitations to commercialization. A qualitative approach was used, carrying on multi-case studies, making the survey through semi-structured questionnaires, oral history and non-participant observation. It was observed that the agro extractive production from Rio dos Cochos is commercialized in: local, regional, national, international and institutional markets. The agro extractive production commercialization is ruled by relations that surpass the mercantile ones: is associated to the relation of farmers among natural resource, culture and to organization ways from this population. The conclusion of the study is that the actions towards to the initiative support to agro extractive commercialization should take these aspects into account, beside the economic ones.

Their scaling properties are investigated for second and third orders, using data from high-Reynolds-number atmospheric boundary layer. It is only when structure functions with disparate sign-symmetry properties are compared can the extended self-similarity detect two different scaling ranges that may exist, as in the example of convective turbulence.

description: We show that the massive noncommutative U(1) theory is embedded in a gauge theory using an alternative systematic way, which is based on the symplectic framework. The embedded Hamiltonian density is obtained after a finite number of steps in the iterative symplectic process, oppositely to the result proposed using the BFFT formalism. This alternative formalism of embedding shows how to get a set of dynamically equivalent embedded Hamiltonian densities.

description: This paper emphasizes the importance of considering the mechanisms that coordinate economic transactions in a decentralized economy, namely the role played by a self-organizing network of entrepreneurial trading firms, for theories aimed at guiding macroeconomic policy. We review a research program that aims to understand how, and how well, trading activities are coordinated in various circumstances by employing agent-based computational (ACE) models of stylized economies where these activities take place in a self-organizing network of markets created and operated by profit-seeking business firms. We discuss how such a research program can yield important policy-relevant insights, beyond those that can be offered by conventional dynamic stochastic general equilibrium (DSGE) models, into several macroeconomic phenomena including the emergence of monetary equilibria in a decentralized economy, the microfoundations of the multiplier process, the costs of a higher trend rate of inflation, and the role of the banking system in economic crises.
title: A Comparative Analysis of Malaria Control Programmes Targeting Delivery of Over-the counter Antimalarial Drugs in Kenya
Creators: name: Abuya, Timothy Osebe
Publisher: name: The Open University
Year: 2009

description: Background: The retail sector is an important channel for increasing access to adequate treatment of fevers in Africa. The objectives of the thesis were to assess the performance of three malaria control programmes targeting private medicine retailers (PMRs) by addressing coverage, utilisation, impact on PMRs' knowledge, practices and implementation processes in Kisii central, Kwale and Bungoma districts of Kenya.

Methods: The thesis used mixed methods including retail audits, surrogate client surveys based on post intervention cross sectional surveys in intervention and controls and mapping of outlets in intervention areas. Qualitative methods including record reviews, in-depth interviews and focus group discussions with programme stakeholders were analysed using thematic framework and policy analysis.

Results: There was a significant impact on PMR knowledge and practice of an NGO-led participatory training programme in Kisii-central district with 60.5% of trained PMRs selling AQ medicines adequately compared to 2.8% in the untrained ones (OR; 53.5: 95% CI 6.7, 428.3). There was some evidence of a limited impact for the MoH-led participatory training programme in the Kwale district, where 18.8% of trained PMRs sold AQ medicines adequately compared to 2.3% of control PMRs (OR; 9.4: 95% CI 1.1, 83.7). This study was unable to show evidence of impact in the social marketing programme in Bungoma district. In terms of coverage, Kisii central covered 27.1% of all outlets in the study sites, compared to 14.1% and 16.7% in Kwale and Bungoma districts, respectively. Policy analysis indicated that, deliberate and careful management of the implementation process, actors involved and establishing a transparent management system with a flexible decision-making processes, is key to successful uptake and impact at retailer level.

Conclusions: PMR interventions operationalised through various institutions in the district level settings at moderate scale are likely to impact on PMR knowledge and practices and lead to increased coverage of appropriate treatment to target populations. Implementation management play a major role in determining programme impact, and should be areas of focus in planning and managing public health programmes.

description: The problem of modernity haunts the Western tradition of philosophy and moves us from disenchantment and disempowerment of the word to its reenchantment. If critical reasoning exorcised the magic power of the word, technological achievements of control reinstated it. More straightforwardly, perhaps, Russian thought traditionally viewed the word as a "technical" or "magical" artifact capable of changing the world. In the beginning was God‘s word but are also the words which open the world of nanotechnology and the digital worlds of software engineering. It is shown how the contributions to this special issue probe various aspects of the word as a technical artefact with technical functions.

description: A learning process with the plasticity property often requires reinforcement signals to guide the process. However, in some tasks (e.g. maze-navigation), it is very difficult (or impossible) to measure the performance of an agent (i.e. a fitness value) to provide reinforcements since the position of the goal is not known. This requires finding the correct behavior among a vast number of possible behaviors without having the knowledge of the reinforcement signals. In these cases, an exhaustive search may be needed. However, this might not be feasible especially when optimizing artificial neural networks in continuous domains. In this work, we introduce novelty producing synaptic plasticity (NPSP), where we evolve synaptic plasticity rules to produce as many novel behaviors as possible to find the behavior that can solve the problem. We evaluate the NPSP on maze-navigation on deceptive maze environments that require complex actions and the achievement of subgoals to complete. Our results show that the search heuristic used with the proposed NPSP is indeed capable of producing much more novel behaviors in comparison with a random search taken as baseline.

description: The puzzle of ultra-high energy cosmic rays (UHECRs) still remains unresolved. With the progress in preparation of next generation experiments (AUGER, EUSO, OWL) grows also the importance of directional analysis of existing and future events. The Galactic magnetic field (GMF) plays the key role in source identification even in this energy range. We first analyze current status of our experimental and theoretical knowledge about GMF and introduce complex up-to-date model of GMF. Then we present two examples of simple applications of influence of GMF on UHECR propagation. Both examples are based on Lorentz equation solution. The first one is basic directional analysis of the incident directions of UHECRs and the second one is a simulation of a change of chemical composition of CRs in the energy range 10^13 - 10^19 eV. The results of these simple analyses are surprisingly rich - e.g. the rates of particle escape from the Galaxy or the amplifications of particle flux in specific directions.

description: Stable dynamical systems are a flexible tool to plan robotic motions in real-time. In the robotic literature, dynamical system motions are typically planned without considering possible limitations in the robot's workspace. This work presents a novel approach to learn workspace constraints from human demonstrations and to generate motion trajectories for the robot that lie in the constrained workspace. Training data are incrementally clustered into different linear subspaces and used to fit a low dimensional representation of each subspace. By considering the learned constraint subspaces as zeroing barrier functions, we are able to design a control input that keeps the system trajectory within the learned bounds. This control input is effectively combined with the original system dynamics preserving eventual asymptotic properties of the unconstrained system. Simulations and experiments on a real robot show the effectiveness of the proposed approach.

description: Broad-band near-infrared images are used to probe the photometric properties of the brightest asymptotic giant branch (AGB) stars within 2 arcminutes of the centers of the dwarf elliptical galaxies NGC 147, NGC 185, and NGC 205. Based on the peak brightness and color of the M giant sequences, ages of 1 Gyr and 0.1 Gyr are predicted for the most recent significant star forming events in NGC 185 and NGC 205, respectively. The brightest AGB stars in NGC 147 indicate that the most recent significant star-forming activity in that galaxy occured \~3 Gyr in the past. The specific frequency of C stars outside of the areas of most recent star formation is found to agree in all three galaxies. The fractional contribution made by C stars to the total AGB light in the K-band is found to be highest in NGC 147 and lowest in the central regions of NGC 205, which is qualitatively consistent with model predictions. The fractional contribution that C stars make to the total K-band light is found to be constant both within and between galaxies, with C stars contributing 2% of the total K-band light. It is concluded that, when averaged over timescales of a few Gyr, these galaxies have turned similar fractions of gas and dust, normalised according to total galaxy mass, into stars.

description: A technique of hydroponic sand culture of vegetables has been recently developed in French Guyana with a surface irrigation based on a drip system. Efforts to simplify this method have led to the use of a porous tubing buried in the sand of the cultivation tank. Two experiments are described for the development of such technique. The choice of a proper water pressure allows it to irrigate continuously. The flow rate of irrigation water through the porous material of the tubing is increased or reduced by the water tension in the sand. Curves of water use compared with the évapotranspiration show a close relation.
Measuring Regional Ethnolinguistic Diversity in Sub-Saharan Africa : Surveys vs. GIS
Creators: name: Gershman, Boris

Publisher: name: American University
Year: 2023

description: This paper compares two approaches to measuring subnational ethnolinguistic diversity in Sub-Saharan Africa, one based on censuses and large-scale population surveys and the other relying on the use of geographic information systems (GIS). The two approaches yield sets of regional fractionalization indices that are moderately positively correlated, with a stronger association across rural areas. These differences matter for empirical analysis: in a common sample of regions, survey-based indices of deep-rooted diversity are much more strongly negatively associated with a range of development indicators relative to their highest-quality GIS-based counterparts.

description: We consider states bound at the flip of the electric field in buckled silicene. Along the electric flip lines a topological confinement is formed with the orientation of the charge current and the resulting magnetic dipole moment determined by the valley index. We compare the topological confinement to the trivial one that is due to a local reduction of the vertical electric field but without energy gap inversion. For the latter the valley does not protect the orientation of the magnetic dipole moment from inversion by external magnetic field. We demonstrate that the topologically confined states can couple and form extended bonding or antibonding orbitals with the energy splitting influenced by the geometry and the external magnetic field.

title: The theme of redemption in Midrash Tehillim as reflected in its Meshalim
Creators: name: Buitelaar, Jerphasina Jacoba
Publisher: name: The Open University
Year: 2009

description: This thesis investigates whether or not an overall unity can be detected in Midrash Tehillim. The present dissertation will argue that there is a unity and coherence in Midrash Tehillim that transcends its discrete pericopes, however these are defined. This coherence takes place in a number of ways. Midrash Tehillim is a lemmatic commentary on the book of Psalms and it follows the sequence, topics and argument of the Psalms. The unity of Midrash Tehillim is also evident at a linguistic level. It is in Rabbinic Hebrew, with some intermingling of Jewish Aramaic. On a third level unity is found in the exegetical techniques of Midrash Tehillim. Also the limited repertory of themes, namely the figure of David, the Temple, including its destruction, and redemption provide unity. It is redemption that is the most characteristic theme of Midrash Tehillim. Finally Midrash Tehillim is unified by the use of a number of literary structures which permeate the work. Two literary structures stand out, namely the Petichah and the Mashal. These Meshalim are particularly artfully composed and a number of them are thematically linked to the redemption. The analysis of the Meshalim of Redemption in Midrash Tehillim has been contextualized in a variety of ways - in terms of previous scholarly work on Midrash, in terms of the state of the text as found in the manuscripts and in terms of the relationship of Midrash Tehillim to other Midrashim.

description: This essay pursues the title of the special issue "In the Beginning was the Word - The Word as a Technical Artefact" and asks if words can be (technical) artefacts. The following thesis will be defended: as long as words are spoken they are part of parole, of spoken language and cannot be an object. Words as some kind of res are signs, but signs as a class of objects cannot be subsumed under the class of artefacts at large. Words can only be treated as artefacts if they are elements of a formal system; to think of them as being somehow technical means requires to understand them without reference to language. Prima facie, this leads to a paradoxical conclusion: if they are words, uttered words, they are part of language; if words are technically produced material entities, artefacts, they are devoid of meaning and are, therefore, not words.

description: We show that the contact map of the native structure of globular proteins can be reconstructed starting from the sole knowledge of the contact map's principal eigenvector, and present an exact algorithm for this purpose. Our algorithm yields a unique contact map for all 221 globular structures of PDBselect25 of length $N \le 120$. We also show that the reconstructed contact maps allow in turn for the accurate reconstruction of the three-dimensional structure. These results indicate that the reduced vectorial representation provided by the principal eigenvector of the contact map is equivalent to the protein structure itself. This representation is expected to provide a useful tool in bioinformatics algorithms for protein structure comparison and alignment, as well as a promising intermediate step towards protein structure prediction.

description: Time series clustering is a challenging task due to the specific nature of the data. Classical approaches do not perform well and need to be adapted either through a new distance measure or a data transformation. In this paper we investigate the combination of a convolutional autoencoder and a k-medoids algorithm to perfom time series clustering. The convolutional autoencoder allows to extract meaningful features and reduce the dimension of the data, leading to an improvement of the subsequent clustering. Using simulation and energy related data to validate the approach, experimental results show that the clustering is robust to outliers thus leading to finer clusters than with standard methods.

description: In 2009, two Canadian poets Stephen Collis and Jordan Scott travelled to five different ecosystems within the borders of British Columbia (BC). At each location, they left a copy of the canonical text of physical anthropology, Darwin’s Origin of Species (1859), open to the elements, for one calendar year. The project, documented in the photographic book Decomp turned the poets’ usual mode of expression on its head: instead of manipulating words to create a final work of linguistic expression, the poets let nature dissolve the integrity of the book, leaving words and morphemes dangling in poetic fragments. The Decomp project allows us to reflect on the environmental influences on language, and the organic structure of language.  The dominant metaphors that describe language come from the biological world, and from Darwin’s theory of evolution in particular. Languages can be said to evolve, mutate, grow, stagnate and even die. Like the words in Darwin’s text left to the elements, languages can be isolated by geographic factors and left to fossilize without continued exchange with other cultures. In the forests B.C. the metaphorical mapping between biology and language becomes literal. We bear witness to the effects of entropy on the book and as the line between animate and inanimate agents blurs. As the poets piece together the fragments of Darwin’s prose in Decomp, we are confronted with such questions, confronted with the ephemeral nature of language and the acts of assembly we all perform every day in the face of linguistic change, and often, decay
