How Dominant Narratives Rise and Fall: Military Conflict, Politics, and the Cold War Consensus
Authors: Krebs Ronald R. 
Published: June 2015

AbstractContemporaries and historians often blame the errors and tragedies of US policy during the Cold War on a dominant narrative of national security: the “Cold War consensus.” Its usual periodization, according to which it came together in the late 1940s and persisted until the late 1960s when it unraveled amidst the trauma of the Vietnam War, fits well with a common theory of change in ideas and discourse. That theory expects stasis until a substantial unexpected failure (in this domain, military defeat) discredits dominant ideas and unsettles dominant coalitions. However, systematic data reveal the standard history of this important case to be wrong. Based on a large-scale content analysis of newspaper editorials on foreign affairs, this article shows that the Cold War narrative was narrower than conventional accounts suggest, that it did not coalesce until well into the 1950s, and that it began to erode even before the Vietnam War's Americanization in 1965. To make sense of this puzzle, I develop an alternative theory of the rise and fall of the narratives that underpin and structure debate over national security. Rooted in the dynamics of public narrative and the domestic politics of the battlefield, the theory argues that military failure impedes change in the narrative in whose terms government officials had legitimated the mission, whereas victory creates the opportunity for departures from the dominant narrative. Process-tracing reveals causal dynamics consistent with the theory: failure in the Korean War, which might have undermined Cold War globalism, instead facilitated the Cold War narrative's rise to dominance (or consensus); and the triumph of the Cuban Missile Crisis made possible that dominant narrative's breakdown before the upheaval of Vietnam. This hard and important case suggests the need to rethink the relationship between success, failure, and change in dominant narratives of national security—and perhaps in other policy domains as well.

Authors: Yvon C , Najuko-Mafemera A , Kanegaonkar R 
Published: June 2015

AbstractBackground:Postural sway can be assessed clinically using the Romberg test, or quantified using dynamic posturography. We assessed the potential use of a novel iPhone application as a method of quantifying sway.Methods:Fifty healthy volunteers performed the Romberg and tandem Romberg tests on a hard floor and on foam in soundproofed and normal clinic rooms. Postural sway was recorded using the D+R Balance application and data were compared using pairedt-tests.Results:Significantly more postural sway was noted in participants when standing with their eyes closed and feet in the ‘tandem’ positionvsfeet together; standing with their eyes closed on foamvson the floor; and standing with their eyes closed on foam with feet in the tandem positionvson the floor with feet together.Conclusion:This feasibility study suggests that the iPhone D+R Balance application deserves further investigation as a means of assessing postural sway and may provide an alternative to current dynamic posturography systems.

Background.Glucocorticoids and serotonin may mediate the link between maternal environment, fetal brain development and ‘programming’ of offspring behaviors. The placenta regulates fetal exposure to maternal hormonal signals in animal studies, but few data address this in humans. We measured prospectively maternal depressive symptoms during pregnancy and mRNAs encoding key gene products determining glucocorticoid and serotonin function in term human placenta and explored associations with infant regulatory behaviors.Method.Bi-weekly self-ratings of the Center for Epidemiologic Studies Depression Scale from 12th to 13th gestational week onwards and term placental mRNAs of 11beta-hydroxysteroid dehydrogenase type 2 (HSD2B11), type 1 (HSD1B11), glucocorticoid (NR3C1), mineralocorticoid receptors (NR3C2) and serotonin transporter (SLC6A4) were obtained from 54 healthy mothers aged 32.2 ± 5.3 years with singleton pregnancies and without pregnancy complications. Infant regulatory behaviors (crying, feeding, spitting, elimination, sleeping and predictability) were mother-rated at 15.6 ± 4.2 days.Results.Higher placental mRNA levels ofHSD2B11[0.41 standard deviation (s.d.) unit increase pers.d.unit increase; 95% confidence interval (CI) 0.13–0.69,p= 0.005],HSD1B11(0.30, 0.03–0.57,p= 0.03),NR3C1(0.44, 0.19–0.68,p= 0.001) andSLC6A4(0.26, 0.00–0.53,p= 0.05) were associated with more regulatory behavioral challenges of the infant. Higher placentalNR3C1mRNA partly mediated the association between maternal depressive symptoms during pregnancy and infant regulatory behaviors (p< 0.05).Conclusions.Higher placental expression of genes regulating feto-placental glucocorticoid and serotonin exposure is characteristic of infants with more regulatory behavioral challenges. Maternal depression acts, at least partly, via altering glucocorticoid action in the placenta to impact on offspring regulatory behaviors.

SUMMARYHelicobacter pyloriinfection is a major cause of peptic ulcer and is also associated with chronic gastritis, mucosa-associated lymphoid tissue (MALT) lymphoma, and adenocarcinoma of the stomach. Guidelines have been developed in the United States and Europe (areas with low prevalence) for the diagnosis and management of this infection, including the recommendation to ‘test and treat’ those with dyspepsia. A group of international experts performed a targeted literature review and formulated an expert opinion for evidenced-based benefits and harms for screening and treatment ofH. pyloriin high-prevalence countries. They concluded that in Arctic countries whereH. pyloriprevalence exceeds 60%, treatment of persons withH. pyloriinfection should be limited only to instances where there is strong evidence of direct benefit in reduction of morbidity and mortality, associated peptic ulcer disease and MALT lymphoma and that the test-and-treat strategy may not be beneficial for those with dyspepsia.
Time valuation of historical outbreak attribution data

Published: June 2015

SUMMARYHuman illness attribution is recognized as an important metric for prioritizing and informing food-safety decisions and for monitoring progress towards long-term food-safety goals. Inferences regarding the proportion of illnesses attributed to a specific commodity class are often based on analyses of datasets describing the number of outbreaks in a given year or combination of years. In many countries, the total number of pathogen-related outbreaks reported nationwide for an implicated food source is often fewer than 50 instances in a given year and the number of years for which data are available can be fewer than 10. Therefore, a high degree of uncertainty is associated with the estimated fraction of pathogen-related outbreaks attributed to a general food commodity. Although it is possible to make inferences using only data from the most recent year, this type of estimation strategy ignores the data collected in previous years. Thus, a strong argument exists for an estimator that could ‘borrow strength’ from data collected in the previous years by combining the current data with the data from previous years. While many estimators exist for combining multiple years of data, most either require more data than is currently available or lack an objective and biologically plausible theoretical basis. This study introduces an estimation strategy that progressively reduces the influence of data collected in past years in accordance with the degree of departure from a Poisson process. The methodology is applied to the estimation of the attribution fraction forSalmonellaandEscherichia coliO157:H7 for common food commodities and the estimates are compared against two alternative estimators.

SUMMARYThe aim of this study was to estimate the healthcare usage and loss of productivity due to gastroenteritis in Australia using the National Gastroenteritis Survey II. In 2008–2009, 7578 participants across Australia were surveyed about infectious gastroenteritis by telephone interview. A gastroenteritis case was defined as a person experiencing ⩾3 loose stools and/or ⩾2 vomits in a 24-h period, excluding cases with a non-infectious cause for their symptoms, such as pregnancy or consumption of alcohol. Lost productivity was considered any lost time from full- or part-time paid work due to having gastroenteritis or caring for someone with the illness. Interference with other daily activities was also examined along with predictors of healthcare-seeking practices using multivariable regression. Results were weighted to obtain nationally representative estimates using Stata v. 13·1. Of the 341 cases, 52 visited a doctor due to gastroenteritis, 126 reported taking at least one medication for their symptoms and 79 cases reported missing ⩾1 days’ paid work due to gastroenteritis. Gastroenteritis results in a total of 13·1 million (95% confidence interval 6·7–19·5) days of missed paid work each year in Australia. The indirect costs of gastroenteritis are significant, particularly from lost productivity.
Attitudes towards online feedback on writing: Why students mistrust the learning potential of models
Authors: Strobl Carola 
Published: June 2015

AbstractThis exploratory study sheds new light on students’ perceptions of online feedback types for a complex writing task, summary writing from spoken input in a foreign language (L2), and investigates how these correlate with their actual learning to write. Students tend to favour clear-cut, instructivist rather than constructivist feedback, and guided self-evaluation through model solutions in online learning environments. However, the former type is too limited to tackle all dimensions of advanced writing. Constructivist feedback, in the form of guided modelling, allows addressing the higher-order concerns involved in summary writing. In addition, it is widely acknowledged that activating the zone of proximal development (ZPD) through cognitive involvement is beneficial to learning. To investigate students’ learning from both types of feedback, a one-group pre-post-test intervention study was set up. Students attending a course on summary writing in L2 within a bachelor programme in Applied Languages (n=38) followed an individual online learning module containing both instructivist fill-the-gap exercises and model solutions with constructivist guiding questions for self-assessment. The students’ actual learning gain was measured through pre- and post-tests, and compared with their perceived learning gain, as expressed in self-evaluation. The comparison reveals a dichotomy between the students’ observed learning curve and an underestimation of their own progress. This dichotomy was found to originate in a mismatch between their expectations towards the online learning module and the characteristics of the constructivist feedback conveyed. This mismatch can be attributed to three key factors: (1) evaluation, (2) linguistic focus, and (3) learner motivation.
A unique foetal case of left ventricular non-compaction associated with arrhythmia, structural cardiac anomalies, and agenesis of the ductus venosus
Authors: Thakur Varsha , Jaeggi Edgar T. , Nield Lynne E. 
Published: June 2015

AbstractA 21-week gestational age foetus was diagnosed with left ventricular non-compaction, Ebstein’s anomaly, sinus bradycardia, first-degree heart block, and agenesis of the ductus venosus. The prognosis was guarded given the constellation of findings, and the foetus was monitored closely. Despite a potentially poor outcome, the foetus survived. Prognosis in foetally diagnosed left ventricular non-compaction is usually poor; however, rarely, foetuses can survive postnatally.

Understanding the factors that put women, especially minority women, at greatest risk facilitates intervention development.
Understanding perennial wheat adoption as a transformative technology: evidence from the literature and farmers
Authors: Adebiyi Jelili , Schmitt Olabisi Laura , Snapp Sieglinde 
Published: June 2015

AbstractPerennial grain crops are an example of a ‘transformative technology,’ in which the functionality and science of the technology differ in a fundamental manner from conventional grain crops. A review of the literature indicates that the motivation for farmer adoption of transformative technologies is complex and poorly understood. At the same time, many studies have found concern and awareness about environmental issues to be significantly and positively correlated with the adoption of no-till agriculture, organic farming and agroforestry. Building on these insights, we conducted an ex ante study of perennial wheat adoption among 11 farmers from Michigan and Ohio. Perennial wheat is not yet commercially available, so a semi-structured interview format was chosen to allow for in-depth discussions of the crop's potential characteristics and uses. Consistent with the literature on transformative technology adoption, farmers who approached us to learn more about perennial grains described soil and environmental quality as their primary motivations for doing so. Farmers suggested a total of ten different uses for perennial wheat, only one of which was mentioned specifically by interviewers. This diversity of proposed uses implied a wide range of criteria for adoption. A striking result was that the ability of perennial wheat to compete with annual wheat on the basis of yield, a focus of researchers, was brought up by only one of the interviewees, as many farmers proposed perennial wheat as a means of solving a problem for which no other crop provided an adequate solution, often by planting perennial wheat on an under-used or marginal area of the farm. This is suggestive that interacting with farmers could alter priorities in perennial grain improvement, as has occurred in other radically transformative agriculture technologies.

AbstractThis study evaluated the effects of organic agriculture manuring systems on carrot (Daucus carota) root morphology and sugar and polyacetylene content. Carrots were harvested three times per season 2006–2007 in a long-term field experiment at Skilleby research farm, Sweden. The effects of pelleted chicken manure, fresh farmyard manure and composted farmyard manure (COM) were compared against control plots left unmanured since the field experiment started in 1991. The carrots were analyzed for root size, root shape, amount of soluble sugars and amount of falcarinol-type polyacetylenes. Differences between manuring systems were found to be smaller than the variation between harvest years and harvest occasions, probably due to the grass-clover ley included in the crop rotation system. On an average for the six harvests, manuring with COM increased root length by 6% compared with fertilizing with pelleted chicken manure. Carrots fertilized with pelleted chicken manure also had 6–7% lower total soluble sugar content than carrots manured with 50 t ha−1 of composted or fresh manure. The falcarinol to total falcarinol-type polyacetylenes ratio was 15.4% in carrots manured with 50 t ha−1 of composted or fresh manure and 14.7% in carrots fertilized with pelleted chicken manure. Seasonal fluctuations in falcarinol-type polyacetylenes were more pronounced in carrots manured with fresh or composted manure than in carrots fertilized with pelleted chicken manure. The results suggest that manuring organic carrots with compost may be the most beneficial strategy, at least in systems where fertilizer is applied only once per crop rotation, whether directly to the carrot crop or in the preceding crop.
Organic grass pea (Lathyrus sativus L.) seeds as a protein source for weaned piglets: Effects of seed treatment and different inclusion rates on animal performance

Published: June 2015

AbstractOrganically produced pork occupies only a small niche in the European meat market, with one of the main reasons being the shortage of locally produced high-quality protein sources. In an effort to promote currently under-utilized protein sources, two feeding trials were conducted with grass pea seeds as feed for weaned piglets. The grass pea (Lathyrus sativus L.) is a hardy grain legume that produces protein-rich seeds, but, as other grain legumes, it contains several anti-nutritive compounds. Apart from trypsin inhibitors and tannins, it also contains the neurotoxin β-N-oxalyl-L-α,β-diaminopropionic acid (ODAP) which may cause nerve damage in farm animals as well as humans. The content of both trypsin inhibitors and ODAP can be greatly reduced by hydrothermal treatment; therefore both raw and hydrothermally treated grass pea seeds were used in the two feeding trials. Diets were fed to 152 and 144 piglets [crosses of (Pietrain × Duroc) × (Landrace × Large White)] respectively, during their rearing phase directly after weaning. In experiment 1, a control diet was compared with two diets containing 10 and 20% raw grass pea seeds, plus one diet with 20% treated grass pea seeds, respectively (as fed basis). In experiment 2, a control diet was compared with one diet containing 20% raw grass pea seeds and two diets containing 20 and 30% treated grass pea seeds, respectively (as fed basis). Grass pea seeds contained 265 and 271 g kg−1 crude protein (as fed basis) in the first and second experiment, respectively, and had an amino acid profile similar to peas (Pisum sativum), including relatively low contents of methionine and cysteine. Hydrothermally treated grass pea seeds were found to be a valuable protein source that was well accepted by piglets. At an inclusion rate of 20–30% in diets, feed intake and daily weight gain of piglets was very similar to that of the control treatment. However, including 20% raw grass pea seeds had a significant negative effect on feed intake in experiment 1 and on daily weight gain in experiment 2. Therefore, hydrothermal treatment of grass pea seeds is recommended prior to feeding to piglets.
Institutional complementarities in the dynamic comparative analysis of capitalism
Authors: AMABLE BRUNO 
Published: June 2015

AbstractThe concept of institutional complementarity plays an important role in the comparative analysis of capitalism. It has often been criticised for being too static and too functionalist, unable to explain change because it would propose a view of institutional forms fitting perfectly with one another. After having presented the concept and its interest for comparative capitalism, this article argues in favour of its usefulness to explain institutional change. However, in order to be integrated fruitfully into a theory of institutional change, it is necessary to have a political economy definition of complementarity, which should not take institutions as some sort of inputs in a production function, but as socio-political compromises established in historically-specific conditions.
Quantum coherence and correlations in quantum system
Authors: Xi Zhengjun , Li Yongming , Fan Heng 
Published: June 2015

AbstractCriteria of measure quantifying quantum coherence, a unique property of quantum system, are proposed recently. In this paper, we first give an uncertainty-like expression relating the coherence and the entropy of quantum system. This finding allows us to discuss the relations between the entanglement and the coherence. Further, we discuss in detail the relations among the coherence, the discord and the deficit in the bipartite quantum system. We show that, the one-way quantum deficit is equal to the sum between quantum discord and the relative entropy of coherence of measured subsystem.

Published: June 2015

AbstractGlobally, more than 800 million people are undernourished while >2 billion people have one or more chronic micronutrient deficiencies (MNDs). More than 6% of global mortality and morbidity burdens are associated with undernourishment and MNDs. Here we show that, in 2011, 3.5 and 1.1 billion people were at risk of calcium (Ca) and zinc (Zn) deficiency respectively due to inadequate dietary supply. The global mean dietary supply of Ca and Zn in 2011 was 684 ± 211 and 16 ± 3 mgcapita−1d−1(±SD) respectively. Between 1992 and 2011, global risk of deficiency of Ca and Zn decreased from 76 to 51% and 22 to 16%, respectively. Approximately 90% of those at risk of Ca and Zn deficiency in 2011 were in Africa and Asia. To our knowledge, these are the first global estimates of dietary Ca deficiency risks based on food supply. We conclude that continuing to reduce Ca and Zn deficiency risks through dietary diversification and food and agricultural interventions including fortification, crop breeding and use of micronutrient fertilisers will remain a significant challenge.
