Authors: McIntyre Cameron P , Lechleitner Franziska , Lang Susan Q , Haghiour Negar , Fahrni Simon , Wacker Lukas , Synal Hans-Arno 
Published: October 2016

AbstractSubstances enriched with radiocarbon can easily contaminate samples and laboratories used for natural abundance measurements. We have developed a new method using wet chemical oxidation for swabbing laboratories and equipment to test for 14C contamination. Here, we report the findings of 18 months’ work and more than 800 tests covering studies at multiple locations. Evidence of past and current use of enriched 14C was found at all but one location and a program of testing and communication was used to mitigate its effects. Remediation was attempted with mixed success and depended on the complexity and level of the contamination. We describe four cases from different situations.
THE TRIAL OF THOMAS KWOYELO: OPPORTUNITY OR SPECTRE? REFLECTIONS FROM THE GROUND ON THE FIRST LRA PROSECUTION
Authors: Macdonald Anna , Porter Holly 
Published: October 2016

ABSTRACTThe trial of Thomas Kwoyelo – the first war crimes prosecution of a former Lord's Resistance Army fighter, and the only domestic war crimes prosecution in Uganda at the time of writing – has been packed with drama, intrigue and politics. The article considers what Kwoyelo's trial means for those most affected by the crimes he allegedly committed, and, more broadly, what it means for the ‘transitional justice’ project in Uganda. The article is concerned primarily with how the trial has been interpreted ‘on the ground’ in Acholiland: by local leadership; by those with a personal relationship to Kwoyelo; by direct victims of his alleged crimes; and by those who were not. Responses to the trial have been shaped by people's specific wartime experiences and if or how his prosecution relates to their current circumstances – as well as by the profound value of social harmony and distrust of higher authorities to dispense justice. We conclude with a discussion of the relevance of our findings for the practice of ‘transitional justice’ across the African continent.

AbstractEssential fatty acids (EFA) are PUFA that are metabolised to long-chain PUFA and are important for brain development and cognitive function. The objective of this study was to determine the association between whole-blood EFA and cognitive function in Tanzanian children. A total of 325 2–6-year-old children attempted the dimensional change card sort (DCCS) tasks to assess executive function. Blood samples were collected for fatty acid (FA) analysis by GC. Associations between executive function and FA levels were assessed by regression. Among the 130 4–6-year-old children who attempted the DCCS tasks, whole-blood levels of linoleic acid were positively associated with executive function, whereas whole-blood levels ofα-linolenic acid and nervonic acid were inversely associated with executive function. A full model including all twenty-five FA explained 38 % of the variation in executive function, whereas a reduced model including only the EFA (α-linolenic acid and linoleic acid), DHA and EPA explained 25 % of the variation in executive function. Children who had sufficient whole-blood levels of EFA were 3·8 times more likely to successfully complete all DCCS tasks compared with children with insufficient EFA. These results suggest that whole-blood FA levels are associated with cognitive abilities. Intervention trials that include assessment of whole-blood FA levels are required to determine the relationships between intake, blood levels and executive function in Tanzanian children.
No difference in acute effects of supplementalv.dietary calcium on blood pressure and microvascular function in obese women challenged with a high-fat meal: a cross-over randomised study

AbstractRecent studies suggest that supplemental Ca (SC) increases the risk of cardiovascular events, whereas dietary Ca (DC) decreases the risk of cardiovascular events. Although frequently consumed with meals, it remains unclear whether Ca can mitigate or aggravate the deleterious effects of a high-fat meal on cardiovascular risk factors. This study aimed to evaluate the effects of SC or DC on blood pressure (BP) and microvascular function (MVF) in the postprandial period in obese women challenged with a high-fat meal. In this cross-over controlled trial, sixteen obese women aged 20–50 years were randomly assigned to receive three test meals (2908 kJ (695 kcal); 48 % fat): high DC (HDCM; 547 mg DC), high SC (HSCM; 500 mg SC–calcium carbonate) and low Ca (LCM; 42 mg DC). BP was continuously evaluated from 15 min before to 120 min after meals by digital photoplethysmography. Before and 120 min after meals, participants underwent evaluation of serum Ca and microvascular flow after postocclusive reactive hyperaemia (PORH) by laser speckle contrast imaging. Ionised serum Ca rose significantly only after HSCM. Systolic BP increased after the three meals, whereas diastolic BP increased after LCM and HDCM. Hyperaemia peak, hyperaemia amplitude and AUC evaluated after PORH decreased with LCM. After HDCM, there was a reduction in hyperaemia peak and hyperaemia amplitude, whereas HSCM decreased only hyperaemia peak. However, comparative analyses of the effects of three test meals on serum Ca, BP and MVF revealed no significant meal×time interaction. This study suggests that in obese women SC and DC do not interfere with the effects of a high-fat meal on BP and MVF.
Stay-green characterization in Belgian forage maize

Published: October 2016

SUMMARYThe term ‘stay-green’ (SG) is used in studies with varieties showing delayed senescence in the field. However, delayed appearance of visual symptoms of leaf senescence does not guarantee a longer duration of photosynthesis. The question arises whether the variation in photosynthetic capacity between silage maize varieties currently on the Belgian market is large enough to define different SG types. Furthermore, physiological traits were investigated as proxies for photosynthesis, including chlorophyll concentration, nitrogen (N) concentration, SPAD readings and greenness score. Finally, the functionality of the SG trait was determined by studying dry matter (DM) and N partitioning in the plants. To address these questions, eight silage maize varieties were monitored at two sites in Belgium over 2 years (2013–2014). Two plant types were found: hereafter called ‘normal’ and ‘SG’. The SG varieties had higher values for photosynthetic capacity and they coincided with higher values for the proxies. Because a higher photosynthetic capacity did not provoke higher assimilate accumulation in the leaves, the SG trait was characterized as a cosmetic one. The SG trait influenced N dynamics in the plant: lower N translocation from the leaves to the ear resulted in lower ear N concentration and lower ear DM yield. No differences in whole-crop N concentration and whole-crop DM yield were found. As the SG trait mainly provokes shifts in partition of DM and N between vegetative and generative tissues, the energy source also shifts from starch (provided by the ear) to cell wall material (provided by the stover).
Development and validation of a low-cost microsurgery Ear Trainer for low-resource settings
Authors: Clark M P A , Westerberg B D , Mitchell J E 
Published: October 2016

AbstractObjective:Chronic suppurative otitis media is a neglected condition affecting up to 330 million people worldwide, with the burden of the disease in impoverished countries. The need for non-governmental organisations to hardwire training into their programmes has been highlighted. An ear surgery simulator appropriate for training in resource-poor settings was developed, and its effectiveness in facilitating the acquisition of headlight and microsurgical skills necessary to safely perform procedures via the ear canal was investigated.Methods:Face validity was assessed via questionnaires. Six tasks were developed: a headlight foreign body removal task, and microscope tasks of foreign body removal, ventilation tube insertion, tympanomeatal flap raising, myringoplasty and middle-ear manipulation. Participants with varying ENT experience were video-recorded performing each task and scored by a blinded expert observer to assess construct validity.Results:Face validity results confirmed that our Ear Trainer was a realistic representation of the ear. Construct validity results showed a statistically significant trend, with experts performing the best and those with limited experience performing better than novices.Conclusion:This study validates our Ear Trainer as a useful training tool for assessing headlight and microsurgical skills required to perform otological procedures.
Networked Justice: Judges, the Diffusion of Ideas, and Legal Reform Movements in Mexico
Authors: INGRAM MATTHEW C. 
Published: October 2016

AbstractExisting research shows that the ideas of judges shape their behaviour. A natural next question to ask is, where do these ideas come from? Yet, there is little empirical evidence regarding the content and distribution of these ideas and even less evidence regarding the sources of these ideas, especially how ideas transfer or diffuse among judges. In this article, a survey of judges in the Mexican state of Michoacán generates original data on the attitudes and professional ties among these legal elites, and a mixed-methods design examines the diffusion of these attitudes along these ties, sequencing quantitative network analyses and interviews with judges to strengthen causal inferences. The core finding that the social structure of judges influences the attitudes judges hold contributes a valuable analytic complement to scholarship on comparative judicial behaviour, and clarifies our understanding of the role of judicial networks in strengthening democracy and the rule of law.

RÉSUMÉCette étude a examiné la pertinence des trois critères de Rowe et Kahn pour le vieillissement réussi à des représentations de soi dans profils de recontre en ligne des aînés:faible probabilité de maladie ou d’invalidité;fonctionnement élevéetl’engagement de la vie active. Dans cette étude transversale, 320 profils de rencontre en ligne des personnes âgées ont été choisis aléatoirement et codés selon ces critères. Les analyses de régression logistique ont déterminé si l’âge, le sexe et la race / ethnicité prédit l’auto-présentation. Peu de profils étaient révélateurs du vieillissement réussi en raison de la faible prévalence des deux premiers critères. Cependant, le troisième critère a été identifié dans de nombreux profils. Les Amérindiens étaient beaucoup moins susceptibles que les autres groupes ethniques pour mettre en évidence les premier et deuxième critères. Présentant le premier critère prédit le jeune âge. Profils de présentations des femmes du troisième critère sont restés très élevés avec l’âge. Les résultats suggèrent que les critères peuvent être sans importance pour les personnes âgées qui cherchent des partenaires, ou peuvent refléter l’exclusivité de cette idée.
Cyclic patterns in the central European tick-borne encephalitis incidence series
Authors: ZEMAN P. 
Published: October 2016

SUMMARYTick-borne encephalitis (TBE) is peculiar due to its unstable dynamics with profound inter-annual fluctuations in case numbers – a phenomenon not well understood to date. Possible reasons – apart from variable human contact with TBE foci – include external factors, e.g. climatic forcing, autonomous oscillations of the disease system itself, or a combined action of both. Spectral analysis of TBE data from six regions of central Europe (CE) revealed that the ostensibly chaotic dynamics can be explained in terms of four superposed (quasi-)periodical oscillations: a quasi-biennial, triennial, pentennial, and a decadal cycle. These oscillations exhibit a high degree of regularity and synchrony across CE. Nevertheless, some amplitude and phase variations are responsible for regional differences in incidence patterns. In addition, periodic changes occur in the degree of synchrony in the regions: marked in-phase periods alternate with rather off-phase periods. Such a feature in the disease dynamics implies that it arises as basically diverging self-oscillations of local disease systems which, at intervals, receive synchronizing impulses, such as periodic variations in food availability for key hosts driven by external factors. This makes the disease dynamics synchronized over a large area during peaks in the synchronization signal, shifting to asynchrony in the time in between.
Comparative genomic fingerprinting of Campylobacter: application in routine public health surveillance and epidemiological investigations

Published: October 2016

SUMMARYA subtyping methodology for Campylobacter, Comparative Genomic Fingerprinting (CGF40), has been described recently. The objective of this study was to assess the utility of CGF40 as a tool to enhance routine public health surveillance of campylobacteriosis. Isolates of Campylobacter from across the province were requested and sent for CGF40 subtyping. Epidemiological data from cases reported to public health officials in Nova Scotia, Canada, from January 2012 to March 2015 were linked with blinded CGF40 subtyping results. CGF40 was epidemiologically valid; subtyping discerned known epidemiologically related isolates and augmented case-finding. Predominant sources and locations of subtype detection from the national reference database showed some study subtypes were rare and even novel to the database, while others were more commonly identified over multiple years and with exposures locally and internationally. A case-case study design was applied to examine risk factors for the most common CGF40 subtypes detected. Differences in the epidemiology of different CGF40 subtypes were observed. Statistically significant associations were noted for specific subtypes with rural residence, local exposure, contact with a pet dog or cat, contact with chickens, and drinking unpasteurized milk. With prospective use, CGF40 could potentially identify unrecognized outbreaks and contribute to epidemiological investigations of case clusters.
Music therapy for palliative care: A realist review
Authors: McConnell Tracey , Porter Sam 
Published: October 2016

ABSTRACTObjective:Music therapy has experienced a rising demand as an adjunct therapy for symptom management among palliative care patients. We conducted a realist review of the literature to develop a greater understanding of how music therapy might benefit palliative care patients and the contextual mechanisms that promote or inhibit its successful implementation.Method:We searched electronic databases (CINAHL, Embase, Medline, and PsychINFO) for literature containing information on music therapy for palliative care. In keeping with the realist approach, we examined all relevant literature to develop theories that could explain how music therapy works.Results:A total of 51 articles were included in the review. Music therapy was found to have a therapeutic effect on the physical, psychological, emotional, and spiritual suffering of palliative care patients. We also identified program mechanisms that help explain music therapy's therapeutic effects, along with facilitating contexts for implementation.Significance of results:Music therapy may be an effective nonpharmacological approach to managing distressing symptoms in palliative care patients. The findings also suggest that group music therapy may be a cost-efficient and effective way to support staff caring for palliative care patients. We encourage others to continue developing the evidence base in order to expand our understanding of how music therapy works, with the aim of informing and improving the provision of music therapy for palliative care patients.
What Difference Does CBDR Make? A Socio-Legal Analysis of the Role of Differentiation in the Transnational Legal Process for REDD+
Authors: Jodoin Sébastien , Mason-Case Sarah 
Published: October 2016

AbstractThis article offers a socio-legal analysis of the role played by the principle of common but differentiated responsibilities (CBDR) in the development, diffusion, and implementation of jurisdictional REDD+ activities throughout the developing world. It employs a qualitative research method known as process tracing to uncover whether and, if so, to what extent and how actors have used CBDR to support the emergence and effectiveness of the transnational legal process for REDD+. The article argues that the transnational legal process for REDD+ reflects a conception of CBDR in which developing country governments may take on voluntary commitments to reduce their carbon emissions, with the multilateral, bilateral, and private sources of financial support and technical assistance provided by developed countries, international organizations, non-governmental organizations, and corporations. This creative conception and application of CBDR has fostered the construction and diffusion of legal norms for REDD+ because it has influenced the interests, ideas, and identities of public and private actors in the North and South. However, the early challenges associated with the implementation of REDD+ reveal a worrying gap between the financial pledges made by developed countries and the costs associated with the full implementation of REDD+, as well as contradictions in the very way in which the responsibilities of various countries have been defined in the context of REDD+. The analysis has important implications for the transnational governance of REDD+, as well as for scholarship on the role of differentiation in the pursuit of effective and equitable climate change solutions.
W. Horsley Gantt, Nick, and the Pavlovian Science at Phipps Clinic
Authors: Ruiz Gabriel , Sánchez Natividad 
Published: October 2016

AbstractWilliam Horsley Gantt is well known as one to the principal proponents of Pavlovian methodology in the U.S. After a long stay at Ivan Petrovich Pavlov’s laboratory in Leningrad from 1925 to 1929, Gantt was invited by Adolf Meyer to join the Henry Phipps Psychiatric Clinic, where he founded and directed the Pavlovian Laboratory from 1930 to 1964. Soon after his arrival at Phipps Clinic in 1931, Gantt began a Pavlovian research program that included the investigation of nervous disturbances in dogs and clinical researches with psychiatric patients. In these studies, Gantt combined a physiological method (the conditional reflexes approach), with a psychiatric problem (nervous disorders) in the context of Meyer’s psychobiology that established the person or individual as unit of analysis. This fact, concentrating upon a single individual, made Gantt studies with dogs recognizable and interesting to physicians, psychologists, and psychiatrists who also worked on individuals. In this paper, we use archival materials –including correspondence, notebooks, and unpublished autobiographical material- to present a case study, that of William Horsley Gantt and his dog Nick. We will explore the reasons why Gantt’ studies on nervous disturbances with this dog captured the interest of psychiatrists and clinical psychologists.
Ca1−xLixAl1−xSi1+xN3:Eu2+ solid solutions as broadband, color-tunable and thermally robust red phosphors for superior color rendition white light-emitting diodes

Published: October 2016

AbstractColor rendition, luminous efficacy and reliability are three key technical parameters for white light-emitting diodes (wLEDs) that are dominantly determined by down-conversion phosphors. However, there is usually an inevitable trade-off between color rendition and luminescence efficacy because the spectrum of red phosphor (that is, spectral broadness and position) cannot satisfy them simultaneously. In this work, we report a very promising red phosphor that can minimize the aforementioned trade-off via structure and band-gap engineering, achieved by introducing isostructural LiSi2N3 into CaAlSiN3:Eu2+. The solid solution phosphors show both substantial spectra broadening (88→117 nm) and blueshift (652→642 nm), along with a significant improvement in thermal quenching (only a 6% reduction at 150 °C), which are strongly associated with electronic and crystal structure evolutions. The broadband and robust red phosphor thus enables fabrication of super-high color rendering wLEDs (Ra=95 and R9=96) concurrently with the maintenance of a high-luminous efficacy (101 lm W−1), validating its superiority in high-performance solid state lightings over currently used red phosphors.

AbstractChemosynthetic symbioses are partnerships between invertebrate animals and chemosynthetic bacteria. The latter are the primary producers, providing most of the organic carbon needed for the animal host's nutrition. We sequenced genomes of the chemosynthetic symbionts from the lucinid bivalveLoripes lucinalisand the stilbonematid nematodeLaxus oneistus. The symbionts of both host species encoded nitrogen fixation genes. This is remarkable as no marine chemosynthetic symbiont was previously known to be capable of nitrogen fixation. We detected nitrogenase expression by the symbionts of lucinid clams at the transcriptomic and proteomic level. Mean stable nitrogen isotope values ofLoripes lucinaliswere within the range expected for fixed atmospheric nitrogen, further suggesting active nitrogen fixation by the symbionts. The ability to fix nitrogen may be widespread among chemosynthetic symbioses in oligotrophic habitats, where nitrogen availability often limits primary productivity.
