description: Au Cameroun comme dans beaucoup d’autres pays en Afrique subsaharienne, les recherches sur le VIH/SIDA se sont confinées dans les zones urbaines et ignorant en quelque sorte les zones rurales. C’est ainsi que ses liens avec l’agriculture et le développement rural n’ont reçu que peu d’attention en raison, dit-on, du manque des données et de la faible prévalence de la maladie dans les zones rurales par rapport aux zones urbaines. Pourtant, les liens réciproques entre la pandémie du VIH/SIDA et le développement rural est aujourd’hui reconnu par tous. La communauté internationale, y compris le Cameroun, cherche à mesurer l’impact de cette maladie sur la population rurale dont les jeunes occupent souvent une place importante. La présente communication vise à répondre à cette préoccupation en analysant l’impact du VIH/SIDA sur les familles rurales avec un accent particulier sur la demande d’éducation des jeunes enfants au Cameroun. En effet, le gouvernement camerounais, à travers le comité national de lutte contre le Sida, cherche les moyens pour encourager les familles, surtout rurales en raison d’un fort taux de déperdition scolaire dans les villages, à maintenir l’éducation de leurs enfants orphelins ou non. Les déterminants économiques, socio-culturels, sanitaires et psychologiques de la demande d’éducation des familles rurales camerounaises en faveur de leurs enfants sont analysés pour la mise en œuvre des politiques économiques et sociales pour accroître l’éducation des jeunes enfants en milieu rural camerounais infecté par le VIH/SIDA.

description: Глобальный энергетический кризис и загрязнение окружающей среды, вызванные главным образом увеличением потребления невозобновляемых источников энергии, побудили исследователей изучить альтернативные энергетические технологии, которые могут использовать энергию, доступную в окружающей среде. Механическая энергия — это наиболее распространенная энергия окружающей среды, которую можно уловить и преобразовать в полезную электрическую энергию. Пьезоэлектрическое, магнитострикционное и магнитоэлектрическое преобразования являются наиболее распространенными механизмами сбора энергии. В результате ожидается, что в ближайшем будущем многие электронные устройства будут питаться от пьезоэлектрических, магнитострикционных и магнитоэлектрических генераторов. В данной статье представлен обзор современного состояния твердотельных устройств сбора энергии, в частности пьезоэлектрических, магнитострикционных и магнитоэлектрических. Изложены принципы преобразования энергии, разъяснены механизмы работы.
The experiences of behaviour interventionists who work with children with autism : occupational stress, coping, and family and child variables

Year: 2009

description: There has been no published research on the people who work intensively with children with autism. The present study was conducted to explore the experiences of Behaviour Interventionists (BIs) who provide one-to-one intervention to children with autism in families' homes. A number of variables were examined, including occupational stress; the relation among stress, strain, and coping; the relation of stress to characteristics of (a) challenging families and (b) children with autism to whom BIs provide support; most and least rewarding aspects of the job; and training and support needs. A total of 65 participants from organizations providing intervention to children with autism in British Columbia and Alberta took part in the study. The two most stressful work roles for BIs were Role Overload (the extent to which job demands exceed personal and workplace resources) and Role Boundary (the extent to which the individual experiences conflicting role demands and loyalties at work). Significant relations were found between stress and coping, and between strain and coping. Coping, however, was not found to moderate the relation between stress and strain. Statistical analyses indicated that there were no correlations between BI stress and characteristics of challenging families to whom BIs provide support. Significant correlations were found between BI stress and two groups of behaviours exhibited by children with autism—sensory-related behaviours and social unrelatedness. The most rewarding aspects of BIs' work pertained to child variables such as helping the child learn and make progress. The most stressful aspects of BIs' work pertained to job variables such as isolation of the job and time pressure. BIs indicated that there were a number of training and support needs, such as increased supervision and support by senior staff, and training on how to deal with difficult parents/family issues. The results are discussed in terms of their clinical and research implications, limitations, and suggestions for future research.

description: We show that fluid stationary models are able to reproduce the observed, negative vertical gradient of the rotation velocity of the extra-planar gas in spiral galaxies. We have constructed models based on the simple condition that the pressure of the medium does not depend on density alone (baroclinic instead of barotropic solutions: isodensity and isothermal surfaces do not coincide). As an illustration, we have successfully applied our method to reproduce the observed velocity gradient of the lagging gaseous halo of NGC 891. The fluid stationary models discussed here can describe a hot homogeneous medium as well as a "gas" made of discrete, cold HI clouds with an isotropic velocity dispersion distribution. Although the method presented here generates a density and velocity field consistent with observational constraints, the stability of these configurations remains an open question.

description: The paper intends to take stock of the situation in the agricultural sector of Rwanda. The main purpose is to identify the gaps in the efforts so far; and subsequently to consider new policy interventions that are needed to achieve the goal of eliminating the ‘Fear of Want’. The sector’s performance is crucial in achieving the MDGs in the country. Noteworthy is that the largest part of Rwandan population agriculture is a livelihood and for the policy makers the sector is continuing to be a development problem. This paper analyzes the links between agriculture, food security and poverty reduction in Rwanda based on available secondary data. It is done in light of two important happenings in the country development scenario after the completion of the reconstruction phase (after war and genocide) of 1994-98. The first is related to the overall development strategy that is followed by the country. Rwanda has set a clear strategy of development in the form of VISION 2020 and also a programme for poverty reduction in the form of PRSP. The second important development was with respect to sector specific initiatives. Four important initiatives merit mentioning- ‘The Strategy and Action Plan for Food security’, ‘The National Agricultural Policy’, the ‘Strategic Plan for Agricultural Transformation’ and the ‘Long-Term Framework for The Implementation of The Comprehensive Africa Agriculture Development Programme (CAADP) in Rwanda’. All these plans were framed for an exhaustive transformation of the agriculture sector so as to bring about the necessary change that is needed to face the challenges of abolishing absolute poverty and hunger. The following hypothesis was framed to guide the analysis: a more productive and profitable agricultural sector is the necessary component in meeting the challenges of attaining food security and abolishing absolute poverty in Rwanda. This hypothesis reflects Rwanda’s national perspective and linked to the country’s development plans (PRSP and VISION 2020) and policies. Analysis enabled to oversee the hypothesis in order to arrive at plausible conclusions related to Rwanda’s agricultural sector performance during last six years (1999-2005). Some crucial areas like cropping pattern, incentives, agricultural prices, public distribution system, implementation of land reform measures etc needs the right attention. If the agricultural sceptics have their way, most Rwandans will face a bleak future of worsening poverty and hunger.

description: Market liberalization created a situation where there are no guaranteed grain prices, no central information source and the need for marketing information increased. Unfortunately, most farmers have little or no access to marketing information. This study evaluates farmers’ perceptions of importance of marketing information; identifies farmers’ sources of grain marketing information; determine farmers’ confidence in and use of marketing information; and assesses determinants farmers’ willingness (WTP) to pay for marketing information. Data used in this study were generated using a structured questionnaire in a survey that covered a random sample of 120 households in traditionally grain surplus-and deficit zones of Kenya. The data were analyzed by descriptive statistics and logit model. Results show that 68% and 55% of the households in grain surplus and deficit zones, respectively, recognized that marketing information was very important. Farmers received marketing information from multiple sources, mainly from traders and other farmers. Most of the farmers who received the information were not utilizing the information due to perceived unreliability of the information and poor access to complementary infrastructure. Education level of the household was the most significant factor that positively affected farmers’ WTP for marketing information. In view of farmers’ perception that information provided by the private sources is unreliable, the public sector ought to provide marketing information as a public service. Smallholder farmers should be catalyzed to form strong associations so as to enjoy economies of scale in accessing marketing information and markets.

description: Tourism in Tanzania has been on the rise since late 1990s when the markets were fully liberalized. This has created a high demand for horticultural produces from tourist hotels located in Serengeti national park in the northwest of Tanzania. Analysis was carried out to determine supply and demand for horticultural produces in Mara region. The annual requirements for horticulture produces in three Serengeti tourist hotels were about 614 tons. These hotels obtain most of the fruits and vegetables from Arusha, Kenya and South Africa which are very far from the park. Due to long distances and poor roads the hotels obtain high priced, low quality and small quantities of produces. The production of horticulture in Mara region is about 620 tons which is more than what is demanded by the hotels. The major problems hindering horticulture production in Mara region include unstable markets, erratic prices and low demand for horticulture produces. The tourist hotels demand locally produced, regular supply, fresh and medium quality horticulture produces while farmers want regular markets for their produces. The Gross Margin analysis indicated that supplier gross profit and growers’ return to labour are high with horticultural crops as compared to other crops. The study recommends that the hotels and growers establish contract agreement to enhance reliable deliveries. To improve production and entrepreneurial skills of the farmers; management support at the beginning of implementation from extension, research, credit and irrigation schemes from local institutions would be necessary.

description: To improve the livelihood of the poor in Sub-Saharan Africa (SSA) much attention has been paid to the development of new agricultural technologies. We hypothesize that farmers can also improve their livelihood through cooperation. Partial cooperation, in which knowledge is shared or bargaining power improved, is relatively common in SSA, while cooperation where all resources are fully shared, which we address, has rarely been investigated. An important pre-requisite to establish such cooperation, is the need for a fair division rule for the gains of the cooperation. This paper combines linear programming and cooperative game theory to model the effects of cooperation of (individual) households on income and farm plans. Linear programming establishes insight in the optimal farm plans in cooperation, and cooperative game theory is used to generate fair division rules. The model is applied to a village in Northern Nigeria. Households are clustered based on socio-economic parameters, and we explore cooperation between clusters. Cooperation leads to increased income and results in changes in farm plans, because more efficient use of resources leads to more intensified agriculture (labour intensive – high value crops).

description: The Rieger periods are solar cycles with a time scale of months, which are present in both flaring activity and sunspot occurrence. These short-term periodicities, tentatively explained by equatorially trapped Rossby-type waves modulating the emergence of magnetic flux at the surface, are considered a peculiar and not yet fully understood solar phenomenon. We chose a stellar system with solar characteristics, UX Arietis, and performed a timing analysis of two 9-year datasets of radio and optical observations. The analysis reveals a 294-day cycle. When the two 9-year datasets are folded with this period, a synchronization of the peak of the optical light curve (i.e., the minimum spot coverage) with the minimum radio flaring activity is observed. This close relationship between two completly independent curves makes it very likely that the 294-day cycle is real. We conclude that the process invoked for the Sun of a periodical emergence of magnetic flux may also be applied to UX Arietis and can explain the cyclic flaring activity triggered by interactions between successive cyclic emergences of magnetic flux.

description: ‘Visual Public Relations’ (co-edited by Simon Collister, doctoral researcher at the University of London, and Sarah Roberts-Bowman, senior lecturer at Northumbria University) emerges as an attempt to move beyond text within the strategic communication field and to acknowledge the integral role that the visual has in shaping communication. The book is organised conceptually: Its first part deals with images, its second part deals with spatial dimensions and its third part deals with research methods, all within a public relations context. The texts’ authors admirably recognise and respond to the relative paucity of research that considers the visual and/or attempts to theorise it – especially in the public relations realm – and should be commended for advancing a paradigm change that recognises and better understands how our different senses play a role in the media content we create, consume and critique, as well as influences how we behave, knowing that such behaviour will likely be mediated in our current environment through one or more multimodal channels.

description: Unemployment which has been identified as the major cause of poverty is a worldwide economic problem. Poverty alleviation has been a great concern to developing countries. The economic burden of unemployment on a society necessitates this study. Consequently, this study analyses the Nigerian agricultural growth rate, its contributions, and examines the linkage and dimension of agricultural growth and unemployment rates. Collected time series data were analyzed with the aid of t – test, Duncan Multiple Range test, Granger Causality test and regression analysis. Results showed that Nigerian agricultural growth rate has an inverse relationship with unemployment and re – establish the Cobweb supply theory. In addition, increase in agricultural growth decrease unemployment and thus can alleviate poverty. Consequently, recommending polices to alleviate poverty should focus on increasing agricultural growth.
On the control theorem for fine Selmer groups and the growth of fine Tate-Shafarevich groups in $\mathbb{Z}_p$-extensions

description: Let $A$ be an abelian variety defined over a number field $F$. We prove a control theorem for the fine Selmer group of the abelian variety $A$ which essentially says that the kernel and cokernel of the natural restriction maps in a given $\mathbb{Z}_p$-extension $F_\infty/F$ are finite and bounded. We emphasise that our result does not have any constraints on the reduction of $A$ and the ramification of $F_\infty/F$. As a first consequence of the control theorem, we show that the fine Tate-Shafarevich group over an arbitrary $\mathbb{Z}_p$-extension has trivial $Λ$-corank. We then derive an asymptotic growth formula for the $p$-torsion subgroup of the dual fine Selmer group in a $\mathbb{Z}_p$-extension. However, as the fine Mordell-Weil group needs not be $p$-divisible in general, the fine Tate-Shafarevich group needs not agree with the $p$-torsion of the dual fine Selmer group, and so the asymptotic growth formula for the dual fine Selmer groups do not carry over to the fine Tate-Shafarevich groups. Nevertheless, we do provide certain sufficient conditions, where one can obtain a precise asymptotic formula.

description: Development of ecological agriculture is the mainstream of the world's agricultural development, as well as the only way to change from traditional agriculture to modern agriculture. This paper expatiates the connotation of ecological agriculture and its significance to the development of western China. There are problems in the development of ecological agriculture in western China, manifested mainly in insufficient subsequent supply, overextension of resources, lack of capital and technology input in the development of ecological agriculture, and imperfect supporting policies. From the new perspective of sociology, countermeasures for developing western ecological agriculture are put forward, including improving the scientific and cultural quality of workers, increasing the input in ecological agriculture and the strength of science and technology promotion, perfecting the policy and regulation system of ecological agriculture, and enhancing the level of information services for ecological agriculture. Finally, it is concluded that development of ecological agriculture in western China should be carried out step by step according to local situation.

Cascading crystallographic transitions and melting curve of elemental zirconium

Subjects: subject: Materials Science (cond-mat.mtrl-sci)
subject: FOS: Physical sciences

description: Precise fitting of the experimental data analyzed separately for each identified crystallographic phase alpha, omega, beta, beta prime and beta double prime yield different bulk moduli Bo and Bo prime and different zero pressure volumes (Vo) than those claimed in the literature. Special attention is given to the bcc phases indicating cascading transitions beta to beta prime to beta double prime associated with volume collapse. The present analysis reveals the existence of a bcc-beta prime phase which is reported here for the first time. It is shown that the first order volume collapse at about 58GPa beta to beta prime is followed by a moderate transition to the bcc-beta double prime phase. The beta prime phase is stable up to 110GPa. Above 110GPa the bcc-beta double prime is dominant and stable up to about 220GPa. The derived bcc-double prime bulk moduli are confirmed by the Lindemann-Gilvarry criterion as Bo and Bo prime simultaneously fit both the P-V EOS and the P-T melting data points (combined approach). The calculated melting curve of elemental Zr, taking into account the thermal pressure Poth shift and the elevated melting Tmo prime at Poth , yield very good fit of the experimental melting data permitting a safe extrapolation to high pressures and temperatures. In addition, the combined approach lead to direct determination of the Greuneisen parameter gammao, needed for applying the approximated Lindemann-Gilvarry melting formula.

description: This paper reviews the connotation of agricultural listed company and the related researches on capital structure theory of enterprises in China. Based on this, research hypothesis is put forward. Capital structure has positive correlation with the scale, growth and debt paying ability of agricultural listed company, and has negative correlation with the profitability, operating capability and cash capacity. Taking 37 agricultural listed companies as the research samples, a total of 15 financial indices reflecting the growth, profitability, enterprise scale, operating capacity, cash capability and debt paying ability are selected to conduct factor analysis. Based on the principle of eigenvalue greater than 1, five factors are ascertained, which can explain 84.04% variance of original independent variables. Factor loading matrix indicates that these five factors can be named as debt paying factor, profitability factor, scale and growth factor, operating capacity factor and cash capability factor. Multiple linear regression is carried out by taking factor score coefficient matrix as the independent variable, and asset-liability ratio of agricultural listed company as the dependent variable. Remove method is applied under 5% significant level. And only profitability factor can pass the test. Result shows that there is significant negative correlation between profitability and asset-liability ratio, which is inconsistent with the assumption and has supported the Pecking Order Theory. The other four factors have not passed the significant test, and have certain negative correlation with the capital structure of enterprises. Among them, correlation between the capital structure and the debt paying factor and scale and growth factor is inconsistent with the assumption. Combining with the analysis result, corresponding countermeasures for optimizing the capital structure of agricultural listed company are put forward.

description: In hep-th/0508024, noncritical M-theory for two-dimensional Type 0A and 0B strings was defined in terms of a double-scaled theory of nonrelativistic fermions in 2+1 dimensions. Here we study this noncritical M-theory at finite temperature. We derive the exact expression for the free energy of its vacuum solution, as a function of a coupling constant $g_M$ and the radius $R$ of the thermal circle. We show that at high temperature, the theory is effectively described by another M-theory solution, whose effective loop-counting coupling scales in a novel way characteristic of M-theory, as $T^3$. Our calculations further suggest that noncritical M-theory is dual to the closed string theory of the topological A-model on a Calabi-Yau, with the radius $R$ of the Euclidean time circle in M-theory playing the role of the string coupling constant of the A-model. In this correspondence, T-duality on the Euclidean time circle of noncritical M-theory implies an S-duality for the topological A-model.

They imply in particular that any fractal boundary is touched by macroscopic clusters, uniformly in its roughness or the configuration on said boundary. Additionally, they imply that any sub-sequential scaling limit of the collection of interfaces between primal and dual clusters is made of loops that are non-simple. We also obtain a number of properties of so-called arm-events: three universal critical exponents (two arms in the half-plane, three arms in the half-plane and five arms in the bulk), quasi-multiplicativity and well-separation properties (even when arms are not alternating between primal and dual), and the fact that the four-arm exponent is strictly smaller than 2. These results were previously known only for Bernoulli percolation ($q = 1$) and the FK-Ising model ($q = 2$). Finally, we prove new bounds on the one, two and four arms exponents for $q\in[1,2]$. These improve the previously known bounds, even for Bernoulli percolation.

description: The robusta coffee market has experienced changes which are characterized by a growth in the demand and the confirmation of Vietnam as the world’s greater producer and exporter leaving behind traditional producers as Indonesia. These changes motivated the analysis of international price integration and the main markets of this commodity: Vietnam, Brazil, Indonesia and India. It was tested the hypothesis that Vietnam transmits prices shocks to the other markets. The framework used the analysis of co-integration and the Vector Error Correction (VEC) model. It was shown that, in the period from 1988 to 2005, the foreign price and the ones from Vietnam, Brazil and Indonesia were integrated and the India’s price was affected by factors that are not common to the other countries. There was no perfect integration and Vietnam, although important, wasn’t the more interdependent market.

description: Рассмотрены три фазовых перехода в твердом метане - низкотемпературный (под давлением), ориентационный фазовый и высокотемпературный квантово-классический. Показано, что последний из них, по степени влияния на различные характеристики твердого метана, превышает фазовый переход II рода, хотя и не является фазовым переходом. Температурная зависимость теплоемкости твердого метана по литературным данным носит фрагментарный характер и имеет пропуск как раз в области высокотемпературного перехода. В этом заключается причина того, что до настоящих исследований этот переход оставался практически незамеченным. Настоящая работа, посвященная выяснению природы высокотемпературного перехода в твердом метане, направлена на восполнение этого пробела и указывает на важное значение этого перехода.

description: We present a detailed description of the first direct measurement of the spatial correlation function of X-ray selected AGN. This result is based on an X-ray flux-limited sample of 219 AGN discovered in the contiguous 80.7 deg^2 region of the ROSAT North Ecliptic Pole (NEP) Survey. Clustering is detected at the 4 sigma level at comoving scales in the interval r = 5-60 h^-1 Mpc. Fitting the data with a power law of slope gamma=1.8, we find a correlation length of r_0 = 7.4 (+1.8, -1.9) h^-1 Mpc (Omega_M=0.3, Omega_Lambda=0.7). The median redshift of the AGN contributing to the signal is z_xi=0.22. This clustering amplitude implies that X-ray selected AGN are spatially distributed in a manner similar to that of optically selected AGN. Furthermore, the ROSAT NEP determination establishes the local behavior of AGN clustering, a regime which is poorly sampled in general. Combined with high-redshift measures from optical studies, the ROSAT NEP results argue that the AGN correlation strength essentially does not evolve with redshift, at least out to z~2.2. In the local Universe, X-ray selected AGN appear to be unbiased relative to galaxies and the inferred X-ray bias parameter is near unity, b_X~1. Hence X-ray selected AGN closely trace the underlying mass distribution. The ROSAT NEP AGN catalog, presented here, features complete optical identifications and spectroscopic redshifts. The median redshift, X-ray flux, and X-ray luminosity are z=0.41, f_X=1.1*10^-13 cgs, and L_X=9.2*10^43 h_70^-2 cgs (0.5-2.0 keV), respectively. Unobscured, type 1 AGN are the dominant constituents (90%) of this soft X-ray selected sample of AGN.

description: The objective of this paper was to analyze whether there is a long-run relationship between Brazilian automobile exports and the real effective exchange rate in Brazil in the 1990-2005 period. The methodology used was cointegration analysis, in particular, the Johansen procedure. Results showed no cointegration between automobile exports and the real effective exchange rate in the period, even when the sample was split to capture distinct exchange rate regimes. The main conclusion is that Brazilian automobile exports in the period are better explained by other factors, such as firm strategies, institutional factors and sector-specific changes.

Topological phase transition and nontrivial thermal Hall signatures in honeycomb lattice magnets

description: We investigate spinon band topology and engineering from the interplay between long-ranged magnetic order and fractionalized spinons, as well as Zeeman coupling under external magnetic fields, in honeycomb lattice magnets. The synergism of Néel order and magnetic fields could reconstruct the spinon bands and drive a topological phase transition from the coexisting phase of long-ranged order and chiral spin liquid with semion topological order to the conventional magnetic order. Our prediction can be immediately tested through thermal Hall transport measurements among the honeycomb lattice magnets that are tuned to be proximate to the quantum critical point. Our theory should also shed light on the critical behavior of honeycomb Kitaev materials with emergent Majorana fermion bands. We suggest a possible relevance to the spin-1/2 honeycomb spin liquid candidate material In$_3$Cu$_2$VO$_9$.

description: This study intends to verify which variables affect the financial leverage of Brazilian agribusiness companies, considering the migration in the indebtedness ranges as proposed in the model of Matarazzo (1998). 26 companies were selected in accordance to the following links of the agribusiness chain flow: a) agricultural production; b) input supplying; and c) processing and distribution. The study was conducted using a multinomial logit model, based on annual data from 1999 to 2005. The results indicate that the variables tangibility of assets, growth opportunities, size and profitability were statistically significant in the explanation of the debt structure of Brazilian agribusiness companies.

description: We review our current understanding of instanton effects in the large N_c limit of QCD. We argue that the instanton liquid can have a smooth large N_c limit which is in agreement with scaling relations derived from Feynman diagrams. We also discuss certain limits of QCD, like the case of high baryon density, in which the Witten-Veneziano relation can be derived from QCD and is saturated by instantons.

description: We introduce a taxonomy that classifies industries using three criteria: net growth in the number of firms; the interrelationship between firm entry and firm exit; and the degree of urban bias in industry growth. We show that in 9 of 15 two-digit NAICS industries investigated, there is evidence of urban bias consistent with a comparative advantage to starting a business in urban markets. The urban advantage is due primarily to faster firm entry rates. Urban and rural firms have similar firm exit rates, consistent with a presumption that there are equal expected profit rates conditional on entry across markets. Urban areas grow faster because they induce faster firm entry and not because urban firms are more likely to succeed.
