SUMMARYAnaemia is a severe public health issue among African preschool-aged children, yet little effective progress has been made towards its amelioration, in part due to difficulties in unravelling its complex, multifactorial aetiology. To determine the current anaemia situation and assess the relative contribution of malaria, intestinal schistosomiasis and infection with soil-transmitted helminths, two separate cross-sectional epidemiological surveys were carried out in Uganda including 573 and 455 preschool-aged children (⩽6 years) living along the shores of Lake Albert and on the islands in Lake Victoria, respectively. Anaemia was found to be a severe public health problem in Lake Albert, affecting 68·9% of children (ninety-five percent confidence intervals (95% CI) 64·9–72·7%), a statistically significant higher prevalence relative to the 27·3% detected in Lake Victoria (95% CI: 23·3–31·7%). After multivariate analysis (controlling for sex and age of the child), the only factor found to be significantly associated with increased odds of anaemia in both lake systems was malaria (Lake Albert, odds ratio (OR)=2·1, 95% CI: 1·4–3·2; Lake Victoria, OR=1·9, 95% CI: 1·2–2·9). Thus intervention strategies primarily focusing on very young children and combating malaria appear to represent the most appropriate use of human and financial resources for the prevention of anaemia in this age group and area. Looking to the future, these activities could be further emphasised within the National Child Health DaysPLUSagenda.

SUMMARYThis study quantifies the rate and intensity of re-infection with human hookworm and Schistosoma mansoni infection 12 months following successful treatment, and investigates the influence of socio-economic, geographical and environmental factors. A longitudinal study of 642 individuals aged over 5 years was conducted in Minas Gerais State, Brazil from June 2004 to March 2006. Risk factors were assessed using interval censored regression for the rate and negative binomial regression for intensity. The crude rate and intensity of hookworm re-infection was 0·21 per year (95% confidence interval (CI) 0·15–0·29) and 70·9 epg (95% CI 47·2–106·6). For S. mansoni the rate was 0·06 per year (95% CI 0·03–0·10) and intensity 6·51 epg (95% CI 3·82–11·11). Rate and intensity of re-infection with hookworm were highest among males and positively associated with previous infection status, absence of a toilet and house structure. Rate and intensity of S. mansoni re-infection were associated with previous infection status as well as geographical, environmental and socio-economic factors. The implications of findings for the design of anti-helminth vaccine trials are discussed.
Thermodynamics of cercarial survival and metabolism in a changing climate
Authors: MORLEY N. J. 
Published: August 2011

SUMMARYCercariae are non-feeding free-living stages in the life cycles of trematodes, highly influenced by temperature. Their life span is brief, limited by the depletion of a non-renewable glycogen store. Warmer temperatures under the influence of climate change may promote the transmission of parasites and therefore understanding their thermobiology forms an important step in discerning the future dynamics of parasite populations. An empirical relationship exists between cercarial mean expected life span and the half-life of the population (t0·5) and therefore t0·5 is a good indicator of glycogen utilization. In this study experimental data on the effects of temperature on cercarial survival is compiled from the scientific literature and evaluated in terms of metabolism using Q10 and Arrhenius activation energy (E* or μ), common measures of temperature-mediated reaction rates. Cercariae have a variable response to temperature, which does not appear to be influenced by their life-history attributes or size. There were little differences in Q10 and E* values between most temperature ranges. In almost half the studies examined (7 of 16) cercariae demonstrated a discrete zone of thermostability over a range equivalent to typical individual mean summer temperatures. Distinct intraspecific differences in temperature responses between 3 laboratory strains of Schistosoma mansoni and 2 natural strains of Echinoparyphium recurvatumsensu stricto were apparent. The importance of these results for cercarial biology under global climate change is discussed.
Samian Ware and Society in Roman Britain and Beyond
Authors: Willis Steven 
Published: August 2011

AbstractSamian ware being widely present, of striking quality, and highly useful to the archaeologist has a special position within Roman studies. This article brings a large body of samian ware data together to explore the nature of its incidence at settlements and in graves. The examination shows how the nature of samian ware distribution is highly structured between different types of site and between different consumers. This is shown to be so in the case of both Britain and the other Western provinces. The findings raise issues around the use of samian ware in society and point the way to harnessing the rich potential of samian as a source of information as understanding of its utility for the archaeologist expands.
Feature types and object categories: Is sensorimotoric knowledge different for living and nonliving things?
Authors: ANKERSTEIN CARRIE A. , VARLEY ROSEMARY A. , COWELL PATRICIA E. 
Published: August 2011

ABSTRACTSome models of semantic memory claim that items from living and nonliving domains have different feature-type profiles. Data from feature generation and perceptual modality rating tasks were compared to evaluate this claim. Results from two living (animals, fruits/vegetables) and two nonliving (tools, vehicles) categories showed that sensorimotoric features were important in object knowledge across both domains. In addition, significant cross-domain similarities and within-domain differences indicated that feature profiles were not determined simply as a function of the living and nonliving domain distinction. The current data support a model of semantic memory rooted in perceptual and motor processes with reduced salience for the “living/nonliving” construct.
Processing reflexives in a second language: The timing of structural and discourse-level constraints
Authors: FELSER CLAUDIA , CUNNINGS IAN 
Published: August 2011

ABSTRACTWe report the results from two eye-movement monitoring experiments examining the processing of reflexive pronouns by proficient German-speaking learners of second language (L2) English. Our results show that the nonnative speakers initially tried to link English argument reflexives to a discourse-prominent but structurally inaccessible antecedent, thereby violating binding condition A. Our native speaker controls, in contrast, showed evidence of applying condition A immediately during processing. Together, our findings show that L2 learners’ initial focusing on a structurally inaccessible antecedent cannot be due to first language influence and is also independent of whether the inaccessible antecedent c-commands the reflexive. This suggests that unlike native speakers, nonnative speakers of English initially attempt to interpret reflexives through discourse-based coreference assignment rather than syntactic binding.
Second language learners' vocabulary expansion is associated with improved second language vowel intelligibility

Published: August 2011

ABSTRACTThis paper tests the predictions of the vocabulary-tuning model of second language (L2) rephonologization in the domain of L2 segmental production. This model proposes a facilitating effect of adults’ L2 vocabulary expansion on L2 perception and production and suggests that early improvements in L2 segmental production may be positively associated with an expanding L2 vocabulary. The model was tested in a study of the L2 vowel intelligibility of adult Japanese learners of Australian English, who differed only in the size of their L2 vocabularies. The results support the predicted association between L2 vocabulary size and L2 vowel intelligibility and the prediction that early-phase L2 vocabulary expansion leads to improved L2 production.
“The spotty cow tickled the pig with a curly tail”: How do sentence position, preferred argument structure, and referential complexity affect children's and adults’ choice of referring expression?
Authors: THEAKSTON ANNA L. 
Published: August 2011

ABSTRACTIn this study, 5-year-olds and adults described scenes that differed according to whether (a) the subject or object of a transitive verb represented an accessible or inaccessible referent, consistent or inconsistent with patterns of preferred argument structure, and (b) a simple noun was sufficient to uniquely identify an inaccessible referent. Results showed that although adults did not differ in their choice of referring expression based on sentence position, 5-year-olds were less likely to provide informative referring expressions for subjects than for objects when the referent was inaccessible. In addition, under complex discourse conditions, although adults used complex noun phrases to identify inaccessible referents, 5-year-olds increased their use of pronominal/null reference for both accessible and inaccessible referents, thus reducing their levels of informativeness. The data suggest that 5-year-olds are still learning to integrate their knowledge of discourse features with preferred argument structure patterns, that this is particularly difficult in complex discourse contexts, and that in these contexts children rely on well-rehearsed patterns of argument realization.
Self-deployment of mobile robotic sensor networks for multilevel barrier coverage
Authors: Cheng Teddy M. , Savkin Andrey V. 
Published: August 2011

SUMMARYWe study a problem of K-barrier coverage by employing a network of self-deployed, autonomous mobile robotic sensors. A decentralized coordination algorithm is proposed for the robotic sensors to address the coverage problem. The algorithm is developed based on some simple rules that only rely on local information. By applying the algorithm to the robotic sensors, K layers of sensor barriers are formed to cover the region between two given points. To illustrate the proposed algorithm, numerical simulations are carried out for a number of scenarios.
A dynamic localization algorithm for a high-speed mobile robot using indoor GPS
Authors: Cho Seungkeun , Park Jaehyun , Lee Jangmyung 
Published: August 2011

SUMMARYThis paper proposes a dynamic localization algorithm for a variable speed mobile robot. In order to localize a mobile robot with active beacon sensors, a relatively long time is needed, since the distance to the beacon is measured using the time-of-flight of the ultrasonic signal. The measurement time does not cause a high error rate when the mobile robot moves slowly. However, with an increase of the mobile robot's speed, the localization error becomes too high to use for accurate mobile robot navigation. Therefore, in this research into high-speed mobile robot operations, instead of using two active beacons for localization, an active beacon and the predicted path are utilized to localize the mobile robot. This new approach resolves the high-localization error caused by the speed of mobile robot. The performance of this method was verified by comparing it to the conventional method through real-world experiments.
Breaking up is hard to do: the economic impact of provisional funding contingent upon evidence development
Authors: Mortimer Duncan , Li Jing Jing , Watts Jennifer , Harris Anthony 
Published: August 2011

AbstractFunding contingent upon evidence development (FED) has recently been the subject of some considerable debate in the literature but relatively little has been made of its economic impact. We argue that FED has the potential to shorten the lag between innovation and access but may also (i) crowd-out more valuable interventions in situations in which there is a fixed dedicated budget; or (ii) lead to a de facto increase in the funding threshold and increased expenditure growth in situations in which the programme budget is open-ended. Although FED would typically entail periodic review of provisional or interim listings, it may prove difficult to withdraw funding even at cost/QALY ratios well in excess of current listing thresholds. Further consideration of the design and implementation of FED processes is therefore required to ensure that its introduction yields net benefits over existing processes.
Pharmaceutical lobbying under postcommunism: universal or country-specific methods of securing state drug reimbursement in Poland?
Authors: Ozierański Piotr , McKee Martin , King Lawrence 
Published: August 2011

AbstractThis paper aims to fill in the gap in research on the effect of pharmaceutical lobbying on drug reimbursement policy, particularly in Poland, a post-communist country. To this end, we conducted in-depth, semi-structured, anonymous, elite interviews in Poland, supplemented by a review of legislation, policy documents, official reports and press articles, as well as observations. Overall, 109 representatives of stakeholders involved in reimbursement policy were interviewed. We identified two key lobbying methods: informal persuasion and third-party endorsements. These methods are coupled with two supplementary ones: lobbying through parliament and ministries, as well as diplomatic pressure. Pharmaceutical lobbying methods in Poland clearly resemble those used in other European countries. What is notable about the Polish case is extensive reliance on informal lobbying and diplomatic pressure.
Social preferences for the inclusion of indirect benefits in the evaluation of publicly funded health services: results from an Australian survey
Authors: McKie John , Richardson Jeff 
Published: August 2011

AbstractThe inclusion of both monetary and non-monetary indirect benefits in economic evaluations of public health programmes and services can have significant distributive effects between patient groups. As a result, some patients may be advantaged and others disadvantaged for reasons not directly related to health outcomes or (direct) treatment costs. In pluralistic democracies, there is a case for consulting the community on the fairness of policies that have such distributive implications. This paper reports the results of two pilot studies aimed at uncovering the preferences of the Australian public for the inclusion of indirect benefits in the evaluation of services for its national health scheme, Medicare. The initial survey found some support for taking account of non-monetary indirect benefits – for example, the social contribution made by parents of young children and carers of elderly relatives. By contrast, there was little support for giving high taxpayers priority access to general Medicare services, to life-saving organ transplants, or to very costly drugs, despite the indirect social benefits of doing so. However, such support increased significantly in the follow-up study when the outcomes were characterised as certain, identifiable and health related, and the opportunity costs of failing to take account of indirect benefits were made very clear. The follow-up survey provided evidence of public scepticism about the willingness or ability of government to use additional tax receipts for socially beneficial purposes, and/or a preference for programmes and services that focus on health rather than welfare more generally.

Near Infrared Microspectroscopy, Fluorescence Microspectroscopy, Infrared Chemical Imaging and High-Resolution Nuclear Magnetic Resonance Analysis of Soybean Seeds, Embryos and Single Cells
Authors: Baianu I. , Korban Schyler , You Tiefeng 
Published: August 2011

AbstractChemical analysis of soybean seeds, somatic embryos and single cells were carried out by Fourier Transform Infrared (FT-IR), Fourier Transform Near Infrared (FT-NIR) Microspectroscopy, Fluorescence and High-Resolution NMR (HR-NMR). The first FT-NIR chemical images of biological systems approaching 1 micron (1μ) resolution are presented here. Chemical images obtained by FT-NIR and FT-IR Microspectroscopy are presented for oil in soybean seeds and somatic embryos under physiological conditions. FT-NIR spectra of oil and proteins were obtained for volumes as small as 2μ3. Related, HR-NMR analyses of oil contents in somatic embryos are also presented here with nanoliter precision. Such 400 MHz 1H NMR analyses allowed the selection of mutagenized embryos with higher oil content (e.g. ~20%) compared to non-mutagenized control embryos. Moreover, developmental changes in single soybean seeds and/or somatic embryos may be monitored by FT-NIR with a precision approaching the picogram level. Indeed, detailed chemical analyses of oils and phytochemicals are now becoming possible by FT-NIR Chemical Imaging/ Microspectroscopy of single cells. The cost, speed and analytical requirements of plant breeding and genetic selection programs are fully satisfied by FT-NIR spectroscopy and Microspectroscopy for soybeans and soybean embryos. FT-NIR Microspectroscopy and Chemical Imaging are also shown to be potentially important in functional Genomics and Proteomics research through the rapid and accurate detection of high-content microarrays (HCMA). Multi-photon (MP), pulsed femtosecond laser NIR Fluorescence Excitation techniques were shown to be capable of Single Molecule Detection (SMD). Therefore, such powerful techniques allow for the most sensitive and reliable quantitative analyses to be carried out both in vitro and in vivo. Thus, MP NIR excitation for Fluorescence Correlation Spectroscopy (FCS) allows not only single molecule detection, but also molecular dynamics and high resolution, submicron imaging of femtoliter volumes inside living cells and tissues. These novel, ultra-sensitive and rapid NIR/FCS analyses have numerous applications in important research areas, such as: agricultural biotechnology, food safety, pharmacology, medical research and clinical diagnosis of viral diseases and cancers.

Published: August 2011

AbstractAn experiment of outdoor rearing was conducted with the available Sukinda (TV) stock of BSM&TC, Sundargarh (SG), CTSSS, Lakha (CTS) and CTR&TI, Ranchi. The objective of this activity is to utilize economic wild life, conserving the associated environment for sustainable rural and tribal development (Raffi and Ramanujam, 2001; Gill and Lal, 2002; Mahapatra, 2009).The crop performance of SG showed highest cocoon yield i.e., 83 cocoons / dfl in 1st crop followed by 80 cocoons / dfl in 3rd crop and 42 cocoons / dfl during 2nd crop. Yellow coloured cocoons dominated (94-96%) the population in all the three crops. The cocoon weight, Shell weight and Silk Ratio were (9.72g, 1.07g&11 %) in 1st crop,(9.77g,1.05g & 10.75%) in 2nd crop and (11.11g,1.79g & 16.11%) in commercial third crop season. The ERR were 41.64 %, 50.00 % and 74.51% in 1st, 2nd and 3rd crop respectively. This approach for semi-domesticated and commercially exploited Sukinda ecoraces can further enhances their potential because of better inherent performance levels under in situ (Suryanarayana and Srivastava, 2005) over the current basic and commercial stocks maintained ex situ.
Foraging Modes of Predators and Behaviors of Prey Determine the Outcome of Multiple Predator Interactions
Authors: Carey Michael P. , Wahl David H. 
Published: August 2011

AbstractInteractions with multiple predator species may differ among prey with different antipredator defenses. The interactions between largemouth bass Micropterus salmoides (a cruising predator) and muskellunge Esox masquinongy (an ambush predator) and prey with different antipredator behaviors, bluegill Lepomis macrochirus and fathead minnow Pimephales promelas, was examined in mesocosms. In the combined predator treatment, no differences were found in the foraging sequence for the cruising predator, whereas the ambush predator increased the number of follows and pursuits. Bluegills altered their behavior across predator treatments by changing their activity levels and habitat use. Ultimately, the ambush predator benefited from the combined predators because of a greater encounter frequency with bluegills that led to more captures and a risk‐enhanced effect on bluegills. The high vulnerability of fathead minnow to individual ambush and cruising predators led to a neutral effect from combined predators. Predator foraging modes and prey behavior must be taken into account to understand natural food webs.
AMBIVALENT CITIZENS
Authors: Açikel Fethi , Ateş Kazim 
Published: August 2011

ABSTRACT
This paper deals with the ambivalent position of Turkish nationalism vis-à-vis the Alevi ethno-religious identity. The Alevi are the largest ethno-religious minority in Turkey. Via a critical pluralist stance, the authors argue that the debates revolving around the origins and nature of the Alevi identity disclose the cultural –and, to a lesser extent, romantic – characteristics of Turkish nationalism and its relative inability to accommodate a fully civic and pluralist notion of national identity. The paper argues that the Alevi question is one of the litmus tests that reveal Turkish nationalism's uneasiness with adopting the idea of an ethno-religiously plural society. Two hegemonic branches of Turkish nationalism conceptualize the Alevi identity through ethno-cultural and religio-cultural lenses. This leads to the Alevi being coded as ‘ambivalent citizens’. This ambivalent status creates a bifurcated yet intertwined process of belonging and non-belonging, authenticity and stigmatization. The paper argues that the unremitting oscillation between the status of ‘genuine self-ness’ and ‘heretical otherness’ discloses the very non-civic and cultural foundations of Turkish nationalism.
