The effect of distance to health-care facilities on childhood mortality in rural Burkina Faso.
No full textThis study aims to investigate the relation between distance to health facilities, measured as continuous travel time, and mortality among infants and children younger than 5 years of age in rural Burkina Faso, an area with low health facility density. The study included 24,555 children born between 1993 and 2005 in the Nouna Health and Demographic Surveillance System. The average walking time from each village to the closest health facility was obtained for both the dry and the rainy season, and its effect on infant (<1 year), child (1-4 years), and under-5 mortality overall was analyzed by Cox regression. The authors observed 3,426 childhood deaths, corresponding to a 5-year survival of 85%. Walking distance was significantly related to both infant and child mortality, although the shape of this effect varied distinctly between the 2 age groups. Overall, under-5 mortality, adjusted for confounding, was more than 50% higher at a distance of 4 hours compared with having a health facility in the village (P < 0.0001, 2 sided). The region of residence was an additional determinant for under-5 mortality. The findings of this study emphasize the importance of geographic accessibility of health care for child survival in sub-Saharan Africa and demonstrate the need to improve health-care access to achieve the Millennium Development Goals

A TIME-SERIES ANALYSIS OF THE U.S. DURUM WHEAT AND PASTA MARKETS
No full textA quarterly, partial-equilibrium vector-autoregression model of the U.S. durum wheat and pasta markets was estimated and simulated under three trade-barrier changes that are of potential relevance for the current round of WTO agricultural negotiations: a rise in the U.S. market-clearing durum wheat quantity from increased imports; a policy- or tariff- reduction-induced decline in U.S. durum wheat price; and a tariff-induced rise in U.S. pasta product prices. In response to each shock, an array of quarterly dynamic response characteristics are examined: response reaction times, direction and pattern of quarterly responses, response durations, response multipliers, and strength of durum/pasta market interrelationships.Industrial Organization,
The right tool for the job? Use of the multiple intelligences and Bloom's taxonomy grid
No full textThis article explores the tacit understanding of teachers in the field of gifted educational practices after their participation in gifted education professional development. The data for this article are drawn from a single-case qualitative study where semi-structured interviews were held with teachers, administrators and support staff in a metropolitan Victorian primary school. The findings lead to two main arguments: first, that some teachers preserved their deeply entrenched beliefs and assumptions about the gifted, the talented and intelligence[s]; and second, that teachers, without critical examination, eagerly adopted and adapted Gardner's Multiple Intelligences theory, overlaid with Bloom's Revised Taxonomy of Thinking as a means for addressing individual differences in the classroom. The article argues that teachers welcomed the Gardner/Bloom matrix for its 'tick-the-box' simplicity, with little insight into the theoretical models. Whilst the matrix had an immediate value in the mixed ability classrooms, in the long term it did not support the learning needs of gifted students. [Author abstract]<br
Performance of Middle-Eastern Alfalfa ecotypes in the Southwestern USA using traditional and contemporary harvest management practices
No full textNon-winterdonnant alfalfa (Medicago sativa L) from the Middle East regrows rapidly and<br>produces high forage yield making it attractive for use in wann-desert regions. In the Middle East, alfalfa<br>is commonly harvested before flowering (bud stage) leaving less than 2 cm stubble. Alfalfa from this reg-ion<br>has unique adaptations to this management and regrow predominately from meristems originating<br>near the stem base. Harvest management may influence productivity of Middle-Eastern alfalfas in<br>mechanized agriculture where late harvest and cutting heights between 8 and 12 cm predominate. We<br>compared yield, persistence, and crown architecture of six Middle-Eastern alfalfa ecotypes under tradi-tional<br>(preflowering + 2 cm stubble) and contemporary harvest management (10% bloom + 10 cm stub-ble),<br>and a combined regime (preflowering + 10 cm stubble) in a 27-month trial in Arizona. Contempo-rary<br>harvest management resulted in significantly higher forage yield in the Middle-Eastern accessions<br>than in either of the other regimes and did not disturb the initiation of regrowth stems. Forage yields of<br>the most productive Middle-Eastern ecotype were 11 to 20% higher than an elite southwestern cultivar<br>regardless of harvest regime. The combined regime, with its higher forage quality, may be preferred as<br>Middle-Eastern alfalfas are utilized in mechanized agriculture.Corresponding Author:

Democracy, traditional leadership and the International Economy in South Africa
No full textThe paper argues that in order to adequately analyse the development of postcolonial democracy - in this case South Africa - a theoretical model has to take into account the context within which that democratic experiment finds itself in. This context is shaped by the international political economy, the circulation of a democracy discourse at both the level of global and local political culture, and the history of state-formation. The paper explores what might explain the resurgence of purportedly 'traditional' modes of governance, symbolised by the 'chief' across several rural landscapes. It argues that the inability of the state to affect fundamental changes in the social, political and economic conditions of the rural hinterlands has created a situation in which local power holders are able to redefine traditional cultural values. In the process of doing so, these local power holders both shape and are shaped by a global discourse of what democracy might be and mean. The paper highlights the debate concerning notions of 'African' forms of democracy, embodied most starkly by some of Nelson Mandela’s writings, which hold that village level deliberation and chieftaincy based upon community consensus may be more appropriate models of democracy than western versions based upon the notions of electoral contestation. This argument stands in sharp contrast to conventional approaches to democracy which would suggest that traditional leadership is an anachronism of lesser developed countries and stands in contrast to western democratic norms and values.
"PROTON SPONGES": A RIGID ORGANIC SCAFFOLD TO REVEAL THE QUANTUM STRUCTURE OF THE INTRAMOLECULAR PROTON BOND
No full textAuthor Institution: Yale University, P. O. Box 208107, New Haven, CT, 06520; Johns Hopkins University, 3400 North Charles Street, Baltimore, MD, 21218; Brock University, St. Catherines, ON, Canada L2S 3A1Spectroscopic analysis of systems containing charged hydrogen bonds (e.g. the Zundel ion, ) in a vibrationally cold regime is useful in decongesting numerous anharmonic features common to room temperature measurements.[Roscioli, J. R.; et. al. Science 2007] This approach has been extended to conjugate acids of the "Proton Sponge" family of organic compounds, which contain strong intramolecular hydrogen bonds between proton donor (D) and acceptor (A) groups at the 1- and 8-positions. By performing vibrational predissociation spectroscopy on cryogenically cooled ions, we explore how the proximity and spatial orientation of D and A moieties relates to the spectroscopic signature of the shared proton. In the cases studied (), we observe strong anharmonic couplings between the shared proton and dark states that persist at these cryogenic temperatures. This leads to intense NH stretching features throughout the nominal CH stretching region (). Isotopic substitution has verified that the oscillator strength of these broad features is driven by NH stretching. Furthermore, the study of A = O(C=O)Ph has provided a spectroscopic snapshot of the shared proton at work as an active catalytic moiety fostering ester hydrolysis by first order acylium fission (). This is apparent by the high frequency carbonyl stretch at , which is a consequence of the strong hydrogen bond to the ether-ester oxygen atom. Thus, these "Proton Sponges" are useful model systems that unearth the quantum structure and reactivity of shared proton interactions in organic compounds
Absence of spontaneous action anticipation by false belief attribution in children with autism spectrum disorder
No full textRecently, a series of studies demonstrated false belief understanding in young children through completely nonverbal measures. These studies have revealed that children younger than 3 years of age, who consistently fail the standard verbal false belief test, can anticipate others' actions based on their attributed false beliefs. The current study examined whether children with autism spectrum disorder (ASD), who are known to have difficulties in the verbal false belief test, may also show such action anticipation in a nonverbal false belief test. We presented video stimuli of an actor watching an object being hidden in a box. The object was then displaced while the actor was looking away. We recorded children's eye movements and coded whether they spontaneously anticipated the actor's subsequent behavior, which could only have been predicted if they had attributed a false belief to her. Although typically developing children correctly anticipated the action, children with ASD failed to show such action anticipation. The results suggest that children with ASD have an impairment in false belief attribution, which is independent of their verbal ability
