description: We discuss HST FOS ultraviolet spectroscopy and NICMOS near-infrared photometry of four young super star clusters in the central region of the irregular starburst galaxy NGC 1569. The new observations coupled with previous HST WFPC2 photometry and ground-based optical spectroscopy allow us to isolate and age-date the hot and cool stellar components of these massive clusters. We analyze the two components A1 and A2 of the brightest super star cluster NGC 1569-A. This cluster received previous attention due to the simultaneous presence of Wolf-Rayet stars and red supergiants. The FOS spectra provide the first evidence for O-stars in NGC 1569-A, indicating a young (5 Myr) stellar component in A1 and/or A2. Comparison with other high-mass star-forming regions suggests that the O- and Wolf-Rayet stars are spatially coincident. If so, cluster A2 could be the host of the very young O- and Wolf-Rayet population, and the somewhat older red supergiants could be predominantly located in A1. The mass-to-light ratio of NGC 1569-A1 is analyzed in five optical and infrared photometric bands and compared to evolutionary synthesis models. No indications for an anomalous initial mass function are found, consistent with a scenario where this cluster is the progenitor of present-day globular clusters. The clusters A1 and A2 are compared to clusters B and #30. The latter two clusters are older and fully dominated by red supergiants. All four super star clusters provide a significant fraction (20 - 25%) of the total optical and near-infrared light in the central region of the galaxy. The photometric properties of the super star cluster population in NGC 1569 resemble those of the populous clusters in the Magellanic Clouds.

description: With the introduction of socially assistive robots in many avenues of children’s lives, it is becoming increasingly vital to understand how children’s perceptions of the robot affect their evaluation and interaction. The main objective of this work is to investigate how children’s anxiety towards robots has influenced their perceptions of their interaction with a Nao robot. We collected data from 37 children (8 - 13 years old) who interacted, for about 30-45 minutes, with the robot which delivered initial pleasantries and four different tasks to help assess their mental wellbeing in a lab setting. We collected audio-visual recordings of the interaction. At the end of the session, we asked children to answer three self-report questionnaires to evaluate: the robot’s role as a confidante, the anxiety towards the robot, and the children’s perception of the robot’s behaviour and capabilities. Based on their responses to the robot’s anxiety questionnaire, children were divided into two categories: “low anxiety” (anxiety score <= median anxiety score) and “high anxiety” (anxiety score> median anxiety score). Our results show that i) most children (89.2%) irrespective of their wellbeing, experience some degree of anxiety towards the robot, ii) children’s anxiety has influenced their willingness to participate in the initial pleasantries conducted by the robot, and iii) children’s anxiety has also affected their evaluations of the robot as a confidante and their perceptions of the robot’s behaviour and capabilities. Findings from this work have significant implications for designing effective and successful robot-led initiatives for assessing mental wellbeing in children, by taking into account their mindsets and dispositions.

description: Low price competitiveness of Tanzania produced rice driven by high production costs calls attention to developing ways of improving efficiency in production. This study was conducted to analyse production costs and factors influencing choice of inputs provider in smallholder irrigated rice production. Specifically, it focused on comparing costs of production, determining factors influencing smallholder irrigated rice farmers’ choice of inputs provider and analysing production cost efficiency. Data were collected from four cooperative irrigation schemes in Pwani and Morogoro regions involving 200 farmers. Production costs were quantified using enterprise budgeting technique and differences analysed using T-test. Factors influencing choice of inputs provider were determined using Logit model. Translog stochastic cost frontier was used for cost efficiency analysis. Study findings indicate that, costs of production stands at 315.47USD/MT. Farmers purchasing inputs through irrigation scheme cooperative had lower production costs than farmers purchasing from other input providers. Factors influencing choice of production inputs provider were distance from the cooperative to nearest town, membership in other organizations, extension services, input quality satisfaction and availability of cash and credit payment mode (p<0.05). Rice output and prices of labour, fertilizer and irrigation water significantly affected costs of production with unit cost of production being decreasing by increasing rice output (p<0.05). Inefficiency in production was significantly influenced by farming experience, planting methods, frequency of weeding, degree of specialization and source of purchased inputs and accounted 82.08% of variability in costs of production (p<0.05). The study concludes that, there is loss of efficiency in production due to high production costs attributed by rice output produced, input prices, source of purchased inputs and other agricultural practices. It is recommended to use labour saving technologies, purchasing inputs through irrigation scheme cooperative and gaining more economies of scale by increasing specialization.

description: This article presents a 125-day experiment to investigate model predictive heat pump control. The experiment was performed in two parallel operated systems with identical components during the heating season. One of the systems was operated by a standard controller and thus represented a reference to evaluate the model predictive control. Both test rigs were heated by an air-source heat pump which is influenced by real weather conditions. A single-family house model depending on weather measurement data ensured a realistic heat consumption in the test rigs. The adapted model predictive control algorithm aimed to minimize the operational costs of the heat pump. The evaluation of the measurement results showed that the electrical energy demand of the heat pump can be reduced and the coefficient of performance can be increased by applying the model predictive controller. Furthermore, the self-consumption of photovoltaic electricity, which is calculated by means of a photovoltaic model and global radiation measurement data, was more than doubled. Consequently, the energy costs of heat pump operation were reduced by 9.0 in comparison to the reference and assuming German energy prices. The results were further compared to the scientific literature and short-term measurements were performed with the same experimental setup. The dependence of the measurement results on the weather conditions and the weather forecasting quality are shown. It was found that the duration of experiments should be as long as possible for a comprehensive evaluation of the model predictive control potential.

description: We present a novel blind source separation (BSS) method, called information geometric blind source separation (IGBSS). Our formulation is based on the log-linear model equipped with a hierarchically structured sample space, which has theoretical guarantees to uniquely recover a set of source signals by minimizing the KL divergence from a set of mixed signals. Source signals, received signals, and mixing matrices are realized as different layers in our hierarchical sample space. Our empirical results have demonstrated on images and time series data that our approach is superior to well established techniques and is able to separate signals with complex interactions.

Year: 2012
Subjects: Consumer/Household Economics

description: The demand for animal products is projected to increase progressively due to extensive urbanization, rapid growth of human population and income dynamics. Despite the potential expansion of beef and dairy production, dairy goat production as an option for enhancing food security and income generation in Kenya is likely to benefit from this prospect. Essentially, goat milk is nutritionally superior to the cow milk. Although the importance of goat milk is empirically known, its valuation from the potential consumers’ point of view, together with the associated price performance, is not well known. The purpose of the current study was to assess consumption and willingness to pay for dairy goat milk. Multistage sampling was used to obtain 131 consumers at households. Primary data was collected using a structured interview schedule. Data collected was on household consumer characteristics, responses to different bid levels for goat milk and socio-economic factors. The study used double-bounded dichotomous choice CVM to assess consumers’ mean WTP for goat milk and logit model to determine socio-economic factors influencing consumers’ WTP. Results indicated that consumers were willing to pay an average premium of 38% above the current prevailing price of cow milk. Age, number of years in schooling and number of children (18 years of age and below) present in a household had a positive and significant effect on WTP. Awareness, gender and the number of adults aged between 19 and 59 years present in a household negatively influenced WTP. The study recommends policy intervention aimed at facilitating development of marketing infrastructure, creation of awareness of important nutritional and health benefits of goat milk, and boosting the development of goat milk dairy processing plants and systems that can add value to goat milk, so as to capture existing market opportunities. This would enhance food security and income generation of the small-scale resource-constrained farmers.

Only experiment can tell us whether G is basically fundamental.

description: We propose a new approach to studying electrical networks interpreting the Ohm law as the operator which solves certain Local Yang-Baxter equation. Using this operator and the medial graph of the electrical network we define a vertex integrable statistical model and its boundary partition function. This gives an equivalent description of electrical networks We show that in the important case of an electrical network on the standard graph introduced by Curtis, Ingerman and Morrow, the response matrix of an electrical network, its most important feature, and the boundary partition function of our statistical model can be recovered from each other. Defining the electrical varieties in the usual way we compare them to the theory of the Lusztig varieties developed by Berenstein, Fomin and Zelevinsky. In our picture the former turns out to be a deformation of the latter. We describe how our approach produces new interesting mathematical structures on the electrical varieties. Our results should be compared to the earlier work started in Lam and Pylyavskyy on the connection between the Lusztig varieties and the electrical varieties.

description: Since the late 1970s summer Arctic sea ice extent has declined by more than 10% per decade and climate projections indicate a high probability of having ice-free summers by the middle to end of the century due to increasing greenhouse gas concentrations (Stroeve et al. 2012). Furthermore, climate model studies have shown that the decline of Arctic sea ice cover can affect weather and climate not only locally but also remotely through changes in the mid-latitude atmospheric circulation. However, the mechanisms beneath the Arctic-mid-latitude linkages are not completely understood. In this study, we investigate the atmospheric response in autumn and winter to Arctic sea ice reduction, using coupled ocean-atmosphere experiments based on the CNRM-CM6 model. We set the sea ice albedo to the ocean value, which yields a complete sea ice loss in summer, a large reduction in autumn and a moderate sea ice decline in winter. We run 100 members of 15 months initialized in January with two configurations: a low-resolution version based on a 130km atmosphere and a 1° ocean (CNRM-CM6-LR), and a high-resolution version which has a 50km atmosphere and a ¼° ocean (CNRM-CM6-HR). Both models have 91 levels on the vertical in the atmosphere (high-top). Comparing the atmospheric response to sea ice reduction in the two model experiments allows to assess the sensitivity of the response to horizontal resolution. Both models show comparable temperature and circulation response in the troposphere with a large polar amplification in autumn associated with a weakening of the mid-latitude westerlies and a narrowing of the subtropical jet stream. In both models we find a cooling over Central Asia in winter, which we interpret as a contribution from dynamical and thermodynamical changes due to the Arctic sea ice loss. In the stratosphere we find a weakening of the polar vortex in both models but occuring in different months: in December in CNRM-CM6-LR and in February in CNRM-CM6-HR. We analyse the differences in the mean state and variability between the two models and link these differences with the simulated response to Arctic sea ice decline.

description: In the present work, based on the first-principles calculations, we systematically discuss the electronic structure, adhesion work, interface energy, chemical bonding strength and interfacial mechanical failure forms of semi-coherent Co(111)/WC(0001) interface. After relaxation, the interface configurations of the middle top (MT) sites migrate toward the hexagonal close-packed hollow top sites (HCP), indicating that the MT occupancy is unstable. The atoms at the interface are more inclined to the HCP sites. The calculated results indicate that the C-terminated HCP1 site interface configuration has the largest adhesion work and the smallest interface energy, which depends on the formation of strong C-Co covalent bonds at the interface. Finally, the strong Co/WC interface configuration formed in the WC-Co composites can effectively carry out load transfer and reduce stress concentration, improving the strength and plasticity of the composites.
The Discovery of a Second Luminous Low Mass X-ray Binary in the Globular Cluster M15

description: We report an observation by the Chandra X-ray Observatory of 4U2127+119, the X-ray source identified with the globular cluster M15. The Chandra observation reveals that 4U2127+119 is in fact two bright sources, separated by 2.7". One source is associated with AC211, the previously identified optical counterpart to 4U2127+119, a low mass X-ray binary (LMXB). The second source, M15-X2, is coincident with a 19th U magnitude blue star that is 3.3" from the cluster core. The Chandra count rate of M15-X2 is 2.5 times higher than that of AC211. Prior to the 0.5" imaging capability of Chandra the presence of two so closely separated bright sources would not have been resolved. The optical counterpart, X-ray luminosity and spectrum of M15-X2 are consistent with it also being an LMXB system. This is the first time that two LMXBs have been seen to be simultaneously active in a globular cluster. The discovery of a second active LMXB in M15 solves a long standing puzzle where the properties of AC211 appear consistent with it being dominated by an extended accretion disk corona, and yet 4U2127+119 also shows luminous X-ray bursts requiring that the neutron star be directly visible. The resolution of 4U2127+119 into two sources suggests that the X-ray bursts did not come from AC211, but rather from M15-X2. We discuss the implications of this discovery for understanding the origin and evolution of LMXBs in GCs as well as X-ray observations of globular clusters in nearby galaxies.

description: Exports are a vital component of a nation’s balance of payments as they are source of foreign exchange and economic growth. Much of the economic growth in Zambia has been driven by copper exports, which have suffered from external shocks such as plummeting prices on the world market. It is against this background that the Government of the Republic of Zambia (GRZ) has devised a number of measures to promote export diversification to non-traditional exports with a view to reducing heavy dependency on copper and stabilise foreign exchange earnings. The non-traditional exports have recorded growth averaging about 30 percent during the period. However, the key determinants of the growth of the non-traditional exports are unknown. This study therefore endeavored to determine factors that affect the growth of two major non-traditional exports in Zambia; Cotton and Tobacco. The study employed annual time series data that spans a period of 34 years from 1980 to 2013. The Auto-Regressive Distributed Lagged (ARDL) model approach to co-integration revealed that cotton and tobacco exports are co-integrated with foreign direct investment, real effective exchange rate, real Gross Domestic Product (GDP) of trade partners, real interest rate and world price. The ARDL analysis revealed that cotton exports are affected by the real interest rate, real effective exchange rate, world price and the real income of the trading partner in the short-run. In the long-run, cotton exports are affected by real interest rate, real effective exchange rate and real GDP. Tobacco exports are significantly affected by real effective exchange rate, real income of the trading partner and foreign direct investment in the short-run while only real effective exchange rate and the real income of the trading partner affect the growth of tobacco exports in the long-run. Granger causality tests revealed that cotton and tobacco exports granger cause agricultural share of GDP. Overall, both exports are highly elastic to exchange rate movements and the importer’s GDP. There is need for government to maintain a stable exchange rate and exploit available markets through increased participation in regional integration.

description: We discuss the implementation of Bayesian inversion methods in order to recover the properties of the intergalactic medium from observations of the neutral hydrogen Lyman-$α$ absorptions observed in the spectra of high redshift quasars (the so-called Lyman-$α$ forest). We use two complementary schemes (i) a constrained Gaussian random field linear approach and (ii) a more general non-linear explicit Bayesian deconvolution method which offers in particular the possibility to constrain the parameters of the equation of state for the gas. While relying on prior assumption for the two-point correlation functions, we show how to recover, at least qualitatively, the 3D topology of the large scale structures in redshift space by inverting a suitable network of adjacent, low resolution lines of sight. We also discuss the inversion of single lines of sight observed at high spectral resolution. Our preliminary investigations suggest that the explicit Bayesian method can be used to derive quantitative information on the physical state of the gas. Redshift distortion is considered by simultaneous constrained reconstruction of the velocity and the density field in real space while assuming statistical correlation between the two fields. The method seems to work well in the strong prior regime where peculiar velocities are assumed to be the most likely realization in the density field. Finally, we investigate the effect of line of sight separation and number of lines of sight. Our analyses suggest that multiple low resolution lines of sight could be used to improve most likely velocity reconstruction on a high resolution line of sight.

description: Women constitute the majority of the population of Rwanda, their role in decision making should therefore be important in the development of the country. However, in rural areas women empowerment is still low while their significant contribution is greater in politics. Women have very low purchasing power in male dominated cash crops and as a consequence it has potentially negative impact on the family income and poverty reduction. The need for analysis of their participation is vital in order to assess barriers as well as opportunities in the coffee value chain. This study aimed at characterizing women in the coffee value chain by examining the extent of their participation and the key factors that influence intensity of participation in Huye District of Rwanda. Data was collected randomly from 246 households where 134 were participants and 112 non-participants. A double-hurdle model was used, whereby at step one, the Probit regression model was used to assess factors influencing participation decision and at step two, a truncated regression model was used to analyze the factors influencing the intensity of participation. The findings indicated that, in Huye District, women were mostly in production of coffee while in processing, women generally participated in lower income generating activities. No women owned coffee stations but some were members of coffee washing station cooperatives. The findings revealed that socio-economic factors that influence women’s participation in coffee production were land size, access to credit and training and key factors that influence the intensity were land size, extension, training and membership to farmer groups. Thus, there is need for policies aiming at enhancing women’s participation in coffee production by promoting land use consolidation, improved access to coffee training and providing extension services as well as facilitating access to credit services.

We then focus on cosmic strings based models and discuss their status in the light of current high-resolution observations from the BOOMERanG, MAXIMA and DASI collaborations. Upcoming megapixel experiments will have the potential to look for non-Gaussian features in the CMB temperature maps with unprecedented accuracy. We therefore devote the last part of this review to treat the non-Gaussianity of the microwave background and present a method for computation of the bispectrum from simulated string realizations.

With the in-plane lattice parameter fixed to that of bulk SrTiO$_3$, the computed superlattice polarization is enhanced above that of bulk BaTiO$_3$ for superlattices with BaTiO$_3$ fraction larger than 40%. In contrast to their bulk paraelectric character, the SrTiO$_3$ layers are found to be {\it tetragonal and polar}, possessing nearly the same polarization as the BaTiO$_3$ layers. General electrostatic arguments elucidate the origin of the polarization in the SrTiO$_3$ layers, with important implications for other ferroelectric nanostructures.

description: Marketing agricultural produce is important amongst smallholder farmers because they derive benefits such as income and rural employment. In developing countries like Kenya, most smallholder farmers are characterized by poor market participation because they lack market information on pineapple marketing. In Bureti district; pineapples have been perceived to have high market value, resulting in trade-offs with staple food. Despite pineapples market value, its market participation has not been fully studied and quantified results in poor prices among small-scale farmers. The objectives of the study were: to describe farmers‟ socio-economic, institutional and market characteristics of pineapple marketing in Bureti district; to determine the factors influencing market participation and its extent, and; to determine the factors influencing the choice of pineapple marketing outlet in Bureti district. The study was conducted in five locations (Kapkisiara, Kisiara, Tulwet, Getarwet and Tebesonik). Multistage sampling procedure was employed to contact 150 respondents. Semi-structured questionnaires were used to collect data from small-scale pineapple farmers through face to face interview. The data was analyzed using the descriptive statistics, Heckman two-stage selection model and Multinomial Logit model. SPSS and STATA computer programs were used to process the data. The results showed that age, gender, education level and pineapple yields significantly influenced the decision to participate in pineapple marketing. Gender, price information, group marketing, marketing experience, vehicle ownership and marketing under contract significantly influenced the extent of market participation. Further, Gender, group marketing, pineapple yield, price information, marketing under contract and vehicle ownership significantly influenced the choice of pineapple marketing outlets. The study recommends that, for holistic market participation among pineapple farmers, proper marketing infrastructure like pineapple hub must be put in place. The government and other policy makers should increase the marketing information and ability of pineapple farmers through avenues like mass media, extension service, and other means of capacity building.

Towards a cost-benefit assessment of farm structural change in European mountain regions

description: Farm structural change increases the productivity and efficiency of farming. In the policy debate, however, there is still a strong attachment to a highly fragmented structure of family farms, especially in countries with high support for the agricultural sector. In these regions, the somewhat “romantic” attachment to small family farms in the policy debate may also be interpreted as a public preference for concomitant non-use values of agricultural production. As a consequence, a cost-benefit analysis including the economic gains from farm structural change as well as the non-use values of small-scale, traditional agriculture may give a new perspective on this policy debate. We here combine results from a discrete choice experiment in a Swiss mountain region with simulation results from an agent-based farm model in the same case study region. We compare the willingness to pay of local people for farm survival with the reduced average income that results from impeded structural change. Results imply that on average WTP is higher than the opportunity costs. However, the differentiation into farm types shows that productive full-time farmers would have to bear the highest opportunity costs that exceed the average WTP by far. We discuss this result with respect to the policy debate and further research.

description: Distinct to type-I Weyl semimetals (WSMs) that host quasiparticles described by the Weyl equation, the energy dispersion of quasiparticles in type-II WSMs violates Lorentz invariance and the Weyl cones in the momentum space are tilted. Since it was proposed that type-II Weyl fermions could emerge from (W,Mo)Te2 and (W,Mo)P2 families of materials, a large numbers of experiments have been dedicated to unveil the possible manifestation of type-II WSM, e.g. the surface-state Fermi arcs. However, the interpretations of the experimental results are very controversial. Here, using angle-resolved photoemission spectroscopy supported by the first-principles calculations, we probe the tilted Weyl cone bands in the bulk electronic structure of WP2 directly, which are at the origin of Fermi arcs at the surfaces and transport properties related to the chiral anomaly in type-II WSMs. Our results ascertain that due to the spin-orbit coupling the Weyl nodes originate from the splitting of 4-fold degenerate band-crossing points with Chern numbers C = $\pm$2 induced by the crystal symmetries of WP2, which is unique among all the discovered WSMs. Our finding also provides a guiding line to observe the chiral anomaly which could manifest in novel transport properties.

description: Increasingly parties within the agri-food supply chain, i.e. producers, processors and retailers, need to respond to consumers’ demands for product quality and safety. The beef sector has numerous stages in its supply chain, and therefore price signals are very important in passing market signals along the chain. This paper uses weekly R3 and R4 steer and heifer prices in the regional markets of the UK and the Republic of Ireland to examine the effectiveness of the EUROP grade system in sending signals to the farm gate.

description: This paper analyzes agglomeration effects and spatial externalities in Hungarian hog sector between 2000 and 2010. Previous studies concentrate primarily on North-American and Western European countries, whilst the research on the Central-Eastern European countries is non-existent. Our study is the first step to fill this gap. We develop a spatial lag – spatial error regression model to capture horizontal and vertical spillover effects, as well as environmental restrictions determining production location in Hungarian hog sector at municipality (LAU-1) level. Our estimations confirms the rationale of distinction of individual and corporate farms in empirical analysis. The pig production were affected by different factors and different ways in the two subsection. From the point of view of spatial economics it seems that this subsections constitute two different “worlds”. The “introvert world” of individual farms is very sensitive to agglomeration effects and spatial externalities. The “extrovert world” of corporate farms is more proof against agglomeration economies and spatial externalities.

description: This article gives a brief qualitative description of the possible evolution of the early Universe between the end of an inflationary epoch and the end of Big Bang nucleosynthesis. After a general introduction, establishing the minimum requirements cosmologists impose on this cosmic evolutionary phase, namely, successful baryogenesis, the production of cosmic dark matter, and successful light-element nucleosynthesis, a more detailed discussion on some recent developments follows. This latter includes the physics of preheating, the putative production of (alternative) dark matter, and the current status of Big Bang nucleosynthesis.
