Development and field testing of an online instrument for measuring the real-time oxidative potential of ambient particulate matter based on dithiothreitol assay
Authors: Puthussery Joseph V. , Zhang Chen , Verma Vishal 
Published: October 2018

Abstract. We developed an online instrument for measuring the oxidative potential (OP)
of ambient particulate matter (PM) using the dithiothreitol (DTT) assay. The
instrument uses a mist chamber (MC) to continuously collect the ambient
PM2.5 in water, and then determines its DTT activity using an automated syringe pump system. The instrument was
deployed at an urban site in the University of Illinois campus, and its field
performance was evaluated by comparing the results with the offline DTT
activity measurements of simultaneously collected PM-laden filters. The
online DTT activity measurements correlated well with the offline
measurements but were higher than both methanol (slope =1.08, R2=0.93) and Milli-Q water (slope =1.86, R2=0.86) extracts of the PM
filters, indicating a better efficiency of the MC for collecting the
water-insoluble fraction of PM. The hourly measurements of ambient PM2.5
OP were obtained by running the online instrument intermittently for 50 days
with minimal manual assistance. The daytime DTT activity levels were
generally higher than at night. However, a 4-fold increase in the hourly
averaged activity was observed on the night of 4 July (Independence Day
fireworks display). The diurnal profile of the hourly averaged OP during
weekdays showed a bimodal trend, with a sharp peak in the morning (around
07:00 LT), followed by a broader
afternoon peak which plateaus around 14:00 LT and starts subsiding at night
(around 19:00 LT). To investigate the association of the diurnal profile of DTT activity with
the emission sources at the site, we collected time-segregated composite PM
filter samples in four different time periods of the day (morning,
07:00–10:00 LT; afternoon, 10:00–15:00 LT; evening, 15:00–19:00 LT; and
night, 19:00–07:00 LT) and determined the diurnal variations in the redox
active components (i.e., water-soluble Cu, Fe, Mn, organic carbon, elemental
carbon, and water-soluble organic carbon). Based on this comparison, we
attributed the daytime OP of ambient PM2.5 to the vehicular (both
exhaust and non-exhaust) emissions and resuspended dust, whereas secondary
photochemical transformation of primary emissions appear to enhance the OP of
PM during the afternoon and evening period.

Published: October 2018

Abstract. Understanding the behavior of the Greenland ice sheet in a warmer climate,
and particularly its surface mass balance (SMB), is important for assessing
Greenland's potential contribution to future sea level rise. The Eemian
interglacial period, the most recent warmer-than-present period in Earth's
history approximately 125 000 years ago, provides an analogue for a warm
summer climate over Greenland. The Eemian is characterized by a positive
Northern Hemisphere summer insolation anomaly, which complicates Eemian SMB
calculations based on positive degree day estimates. In this study, we use
Eemian global and regional climate simulations in combination with three
types of SMB models – a simple positive degree day, an intermediate
complexity, and a full surface energy balance model – to evaluate the
importance of regional climate and model complexity for estimates of
Greenland's SMB. We find that all SMB
models perform well under the relatively cool pre-industrial and late Eemian.
For the relatively warm early Eemian, the differences between SMB models are
large, which is associated with whether insolation is included in the
respective models. For all simulated time slices, there is a systematic
difference between globally and regionally forced SMB models, due to the
different representation of the regional climate over Greenland. We conclude
that both the resolution of the simulated climate as well as the method used
to estimate the SMB are important for an accurate simulation of Greenland's
SMB. Whether model resolution or the SMB method is most important depends on
the climate state and in particular the prevailing insolation pattern. We
suggest that future Eemian climate model intercomparison studies should
include SMB estimates and a scheme to capture SMB uncertainties.

Successful Public Health Information System Database Integration Projects: A Qualitative Study
Authors: Roberts Matthew Wesley 
Published: October 2018

ObjectiveTo explore the most important public health information system database integration project success factors, whether technological, organizational, project-specific, or external in nature.MethodsThis study involved a cross-case design. Cases were identified through literal replication logic and screened through a survey and literature review. Study participants were interviewed through hour-long sessions with a semi-structured guide. Survey responses, interview transcripts and available documents were coded and analyzed deductively, with matrices developed to illustrate relationships. ResultsLeadership among the project’s participants is the most important integration project success factor. Executive sponsors champion the initiative. Informaticians facilitate communication and system requirement collection. Program directors contribute substantive energy to the project and remove obstacles. Other factors substantially contribute to project success. Strong Financial Management and Support promotes project initiation. Technological aspects impact the functionality of the final product. Utilizing formal project management techniques, particularly the Agile software development methodology, contributes to successful project resolution by ensuring daily operational effectiveness.DiscussionThe principal finding illustrates project leadership transcending the role of the executive sponsor. Other participants, notably informaticians and program directors, substantially contribute to the project’s success. Additionally, the Agile software development methodology is emerging as a successful approach to project management for these and related projects. ConclusionInvesting in the leadership and project management skills of database integration project participants could improve the success of future projects. State health department staff considering these projects should carefully select project participants and train them accordingly.
Food Trends and Popular Nutrition Advice Online – Implications for Public Health
Authors: Ramachandran Divya , Kite James , Vassallo Amy Jo , Chau Josephine Y , Partridge Stephanie R , Freeman Becky , Gill Timothy 
Published: October 2018

AbstractObjectives: Consumers routinely seek health and nutrition-related information from online sources, including social media platforms. This study identified popular online nutrition content to examine the advice and assess alignment with the Australian Guideline to Healthy Eating (AGHE).Methods: We used Facebook page likes as an indicator of popularity to identify online nutrition and diet content. Websites and blogs associated with pages that had more than 100,000 Australian likes on 7th September 2017 were included. The dietary advice promoted was collected and compared with the AGHE. Results: Nine Facebook pages met the inclusion criteria. The four most-liked pages were hosted by celebrities. Only two pages and their associated websites had advice consistent with AGHE recommendations. The concept of “real food” was a popular theme online. While most sources advocated increasing vegetable consumption and reducing processed food, other advice was not evidence-based and frequently conflicted with the AGHE.Discussion: Health information seekers are exposed to a variety of online dietary information and lifestyle advice. While few public health goals are promoted, there are many conflicts with AGHE. Public health organisations promoting AGHE on Facebook are few and not as popular.Conclusion: Public health organisations need to be more engaged on popular internet platforms such as Facebook. The prevailing popular nutrition advice online may increase consumer confusion, scepticism and even avoidance of dietary advice. Proactive efforts are needed by public health organisations, in partnership social marketing experts, to create and share engaging and accurate nutrition content. Partnership with celebrities should be explored to improve reach and impact of evidence-based diet recommendations online.
A Causally Naïve and Rigid Population Model of Disease Occurrence Given Two Non-Independent Risk Factors
Authors: Dammann Olaf , Chui Kenneth , Blumer Anselm 
Published: October 2018

We describe a computational population model with two risk factors and one outcome variable in which the prevalence (%) of all three variables, the association between each risk factor and the disease, as well as the association between the two risk factors is the input. We briefly describe three examples: retinopathy of prematurity, diabetes in Panama, and smoking and obesity as risk factors for diabetes. We describe and discuss the simulation results in these three scenarios including how the published information is used as input and how changes in risk factor prevalence changes outcome prevalence.

This article presents a historical discussion about the conceptual and historical limits of the irreligious phenomenon of atheism. The main aim is to approach the methodological lines of the study of atheism and to project them in the historical, cultural and religious context of Ancient Greece. The formal characteristics of the Greek religion will be analysed to understand the existence of sceptical positions about the existence of the gods. The study of the different historical sources allows us to analyse these atheistic positions, from the beginning of the philosophy with the pre- socratic philosophers until the classical period with Plato. It is a huge historical period with complex cultural events like the phenomenon of disbelief.
La musique au défi de la phénoménologie de Charles Peirce (ou : y a-t-il une secondéité musicale?)
Authors: Chateau Dominique 
Published: October 2018

La discussion sur la musique qui utilise la plus célèbre des triades peirciennes – icône, indice, symbole – achoppe, ce qui ne signifie nullement que la discussion soit close. On propose ici de la transporter sur un autre plan du système du sémioticien, celui quoffre la triade phénoménologique de la priméité, secondéité et tiercéité. Plus précisément, il s’agit de se demander si on peut parler de tiercéité en musique, c’est-à-dire de pensée. On la dit volontiers asémantique ; est-ce à dire qu’elle ne communique aucune pensée ?
Biofiction à la première personne : La Rose dans le bus jaune d’Eugène Ébodé
Authors: Raynaud Claudine 
Published: October 2018

La Rose dans le bus jaune (2013) d’Eugène Ébodé est une « biofiction » à la première personne qui met en scène Rosa Parks (1913-2007), figure légendaire du mouvement des droits civiques. En choisissant de raconter à la fois le quotidien de Rosa et la journée mythique du 1er décembre 1955 qui conduisit à son arrestation, le roman rejette au second plan des figures historiques comme Martin Luther King Jr et réécrit l’histoire américaine du point de vue des marges. Le genre de la biofiction permet une reconstitution des événements, mais prend certaines libertés avec les faits : Ébodé crée le personnage de Douglas White, métis qui se fait passer pour blanc, celui-là même auquel Rosa devrait céder sa place, et poursuit ainsi sa réflexion sur le métissage. Il explore également les correspondances entre les luttes d’indépendance africaines et le combat des Noirs américains pour l’égalité. Supplément aux écrits biographiques de Rosa Parks, La Rose est un roman traversé par le blues qui croise Afrique et Amérique.
La Divine Chanson : les musiques funambules ou Papa Legba aux carrefours des continents
Authors: Delmeule Jean-Christophe 
Published: October 2018

Si le continent africain résonne en Amérique, c’est par la voix de Sammy Kamau-Williams, double du poète-musicien Gil Scott-Heron, qui a réellement existé. Le narrateur de La Divine Chanson, un chat nommé Paris, est un autre avatar de son maître. Ce félin roux dessine aussi en creux la silhouette d’Abdourahman A. Waberi, écrivain djiboutien, qui propose ainsi une biofiction inspirée des pratiques musicales noires américaines. Que reste-t-il en effet des empreintes du passé africain dans le présent afro-américain ? Et que peut-on reconstruire sur l’amnésie et la honte ? Des récits féériques, des tentatives de filiations, des projets de Révolution. Mais surtout une musique qui relie le Nord et le Sud, et longe les berges du Mississippi. Le blues envahit ainsi les espaces comme il accompagne les dérives funambules. Le texte, dès lors, politique, essentiellement esthétique, joue de superpositions plurielles, et il inscrit ses propres sillons poétiques dans l’ombre magique d’un dieu béninois devenu loa haïtien, Papa Legba, posté aux carrefours des existences, à la croisée du passé, du présent et de l’avenir.
« Le deuxième livre de l’ethnographe » africaniste : de Michel Leiris à Valentin Yves Mudimbe

Published: October 2018

Pourquoi certains chercheurs africanistes éprouvent-ils lebesoin d’écrire un récit de vie ou un carnet devoyage avant ou après une monographie scientifique soldant uneenquête de terrain ? La première forme aurait-elletout simplement une dimension résiduelle, réduite ainsiau statut d’appendice de la seconde, ou au contraire les deuxseraient-elles complémentaires ? Ces problématiquescouvrent un champ et une période relativement vastes, allant dela pratique de la réflexivité chez les chercheurs ensciences humaines et sociales – Michel Leiris, Georges Balandier,Jean-Loup Amselle – aux continuités et recoupements quel’on observe dans les études littéraires etcritiques – Alain Ricard, Bernard Mouralis, Valentin-YvesMudimbe, Manthia Diawara, etc. C’est pour faire place auxcontinuités plutôt qu’aux ruptures que l’onrelativise la formule de « deuxième livre del’ethnographe », de Vincent Debaene, luipréférant celle du double livre, favorable auxrecoupements entre productions, par-delà les genres.
Mobilités de l’oeuvre : exils, errances et retours
Authors: Mazauric Catherine 
Published: October 2018

Dans l’oeuvre d'Henri Lopes, partir, c’est se faire autre : les mobilités spatiales s'y conjuguent à une essentielle plasticité identitaire. À travers des êtres de plusieurs vies et de multiples appartenances en proie à l’« enracinerrance », figures ubiquitaires tout à la fois ancrées « au Pays » et désancrées, l’oeuvre lopésienne ne cesse ainsi de déplacer et fluidifier les catégories à travers lesquelles sont ordinairement inventoriés tant les formes et situations de déplacement (voyage, exil, migration, immigration, errance, retour, etc.) que les lieux entre lesquels elles se jouent, les tonalités affectives qui leur sont associées et les écritures qui en rendent compte. Le paysage intérieur sur fond duquel son oeuvre se déploie, formé des méandres du fleuve, de l’île et de la rive, étant lui-même mobile, elle conjoint le mouvement à une forme de stabilité, l’élan à une possibilité de réassurance constamment maintenue. La séduction qui en émane ne tiendrait-elle finalement pas à sa propension à solliciter les zones intermédiaires du psychisme, celles où s’élaborent les possibles de l’aventure humaine ?
L’histoire et son traitement dans l’oeuvre d’Henri Lopes
Authors: Mouralis Bernard 
Published: October 2018

À la différence de Mongo Beti ou de Tchicaya U Tam’si, Henri Lopes, dans ses romans, n’a pas cherché à retracer une histoire avec la périodisation qu’un tel projet implique. Dans un premier temps, on examinera l’intérêt que Lopes porte à l’écriture d’une chronique sociale nettement insérée dans le contexte de l’Afrique des années 1960-1970, avec le recueil de nouvelles Tribaliques (1971), La Nouvelle Romance (1976) et Sans tam-tam (1977). Puis, avec Le Pleurer-rire (1982), il sort du cadre strict de la chronique en proposant, dans la lignée de Rabelais et M.A. Asturias, le portrait d’un dictateur, truculent, cruel, obscène. L’article s’interroge enfin sur la façon dont Lopes ne cesse d’entrelacer l’histoire et l’Histoire, en s’appuyant notamment sur le cas de Marie-Ève, l’héroïne peintre de Sur l’autre rive (1992), et sur des textes plus nettement autobiographiques (Ma grand-mère bantoue et mes ancêtres les Gaulois, 2003) ou relevant de l’autofiction (Le Méridional, 2015).
Henri Lopes, anti-« parrain » de la phratrie congolaise
Authors: Gahungu Céline 
Published: October 2018

Entre 1969 et 1980, protecteur politique et modèle littéraire, Henri Lopes se refuse à exercer une autorité charismatique sur les novices de la phratrie. Au fil des entretiens, revient une antienne : il n’est pas un mentor et renvoie volontiers les débutants qui le sollicitent aux Lettres à un jeune poète de Rilke. Susciter « l’envie » de prolonger son oeuvre « insolente », faire de la phratrie un laboratoire créatif destiné aux apprentis et les « aider » à se « sentir écrivains » – ce sont là les seules « leçons » dispensées par le romancier dont les textes réfléchissent, à l’infini, la dynamique exploratoire de son écriture.
Distributed Bayesian networks reconstruction on the whole genome scale
Authors: Frolova Alina , Wilczyński Bartek 
Published: October 2018

Background
Bayesian networks are directed acyclic graphical models widely used to represent the probabilistic relationships between random variables. They have been applied in various biological contexts, including gene regulatory networks and protein–protein interactions inference. Generally, learning Bayesian networks from experimental data is NP-hard, leading to widespread use of heuristic search methods giving suboptimal results. However, in cases when the acyclicity of the graph can be externally ensured, it is possible to find the optimal network in polynomial time. While our previously developed tool BNFinder implements polynomial time algorithm, reconstructing networks with the large amount of experimental data still leads to computations on single CPU growing exceedingly.

Results
In the present paper we propose parallelized algorithm designed for multi-core and distributed systems and its implementation in the improved version of BNFinder—tool for learning optimal Bayesian networks. The new algorithm has been tested on different simulated and experimental datasets showing that it has much better efficiency of parallelization than the previous version. BNFinder gives comparable results in terms of accuracy with respect to current state-of-the-art inference methods, giving significant advantage in cases when external information such as regulators list or prior edge probability can be introduced, particularly for datasets with static gene expression observations.

Conclusions
We show that the new method can be used to reconstruct networks in the size range of thousands of genes making it practically applicable to whole genome datasets of prokaryotic systems and large components of eukaryotic genomes. Our benchmarking results on realistic datasets indicate that the tool should be useful to a wide audience of researchers interested in discovering dependencies in their large-scale transcriptomic datasets.
Benzylalkohol – Bestimmung von Benzylalkohol in der Luft am Arbeitsplatz mittels Gaschromatographie nach Thermodesorption [Air Monitoring Methods in German language, 2018]

Published: October 2018

AbstractThis analytical method is a validated measurement procedure for the determination of benzyl alcohol [100‐51‐6] in workplace air in a concentration range of one tenth up to twice the currently valid MAK value of 22 mg/m3. With this method simultaneously airborne benzyl alcohol in the gaseous state as well as particles are collected. Sampling is performed by drawing a defined volume of air through a quartz fibre filter located in the sampling head with an adsorption tube filled with Tenax TA connected downstream using a suitable pump. The flow rate is set to 0.066 L/min with a recommended air sample volume of approx. 4 litres. The collected benzyl alcohol is thermally desorbed and then analysed by means of gas chromatography using two detectors, a FID for quantification and a MSD to recognise potential interferences. The quantitative determination is based on a calibration function obtained by means of a multi‐point calibration. The limit of quantification is 0.24 mg/m3based on an air sample of approx. 4 litres.
