L’histoire du temps présent, une histoire (vraiment) comme les autres ?
Authors: Delacroix Christian 
Published: April 2018

Pour répondre à la question « L’histoire du temps présent est-elle une histoire comme les autres », l’article rappelle que cette histoire s’est affirmée et institutionnalisée en Europe et ailleurs, à partir de la fin des années 1970, sous la contrainte de revendications mémorielles concernant des passés difficiles à assumer par les communautés nationales, des « passés qui ne passent pas ». Pour faire reconnaître la légitimité scientifique de l’histoire du passé récent, les historiens qui la pratiquent ont dû argumenter non seulement contre les objections qui leur étaient opposées mais aussi pour tenter de cerner la singularité « temporelle » d’une telle histoire, notamment par l’existence de témoins vivants des périodes étudiées. L’histoire du temps présent a été un des vecteurs principaux de la promotion des mémoires comme objet historique à part entière, mais du même coup elle s’est trouvée en « première ligne » dans les débats sur les rapports entre histoire et mémoire. Parmi les critiques récurrentes portées à l’histoire du temps présent il y a les rapports ambigus qu’elle entretient avec les demandes sociales, aussi ses partisans ont-ils réaffirmé leur adhésion prioritaire avec le projet d’objectivité et de vérité commun à tous les historiens. C’est, pour finir, peut-être autour de la notion de contemporanéité entendue comme une exacerbation de la présentification d’un passé proche et vivant, que les historiens du temps présent trouvent ce qui fait leur relative singularité au sein de la discipline.

Gritos, susurros y silencios dictatoriales. La historiografía chilena y la dictadura pinochetista
Authors: Ortiz de Zárate Verónica Valdivia 
Published: April 2018

Este artículo revisa la producción historiográfica chilena respecto de la dictadura, liderada por el general Augusto Pinochet. El artículo sostiene que el período dictatorial no ha generado en Chile un campo/área de estudios consistente y que perdure en el tiempo, pues la atención ha estado concentrada más bien en su proyección a la post dictadura y las responsabilidades de los gobiernos civiles en sus continuidades, como en las vías de construcción al socialismo y la experiencia chilena de la Unidad Popular. Tal derrotero se relaciona con el debate político en Chile sobre el desmontaje de esa herencia. Ello ha incidido en una producción desbalanceada, con temas excesivamente analizados, otros de menos repercusión y muchos más, abandonados. Gritos, susurros y silencios son las metáforas que expresan tales tendencias. Palabras clave: Dictadura. Historiografía. Chile. Pinochet. Abstract:This article reviews the historiography concerning the Chilean dictatorship led by General Augusto Pinochet. It claims that the dictatorial period has not established, at least in Chile, a consistent and sustained field of studies, as attention has tended to focus more on its repercussions in the post-dictatorial period and the complicities of civilian governments on such continuities, as well as on the different "roads" to socialism and the experience of the Popular Unity. These emphases are connected to Chile's current political debates about the feasibility or desirability of dismantling Pinochet's legacies, with their attendant incidence on an unbalanced historiographic production: some topics have been analized in excess, others have received less attention, and many more have been simply ignored. Shouts, whispers and silences are the metaphors here employed to convey those tendencies. Keywords: Dictatorship--Historiography--Chile--Pinochet.

Objectives:
Helicobacter pylori (H.
Pylori) is a Gram
(-), microaerophilic bacteria and the etiological factor of chronic active
gastritis and peptic ulcer. Some studies indicated that this bacterium found at
oral cavity which is a potential reservoir for stomach. Several studies showed
that H. pylori may found in saliva
and subgingival plaque of chronic periodontitis patients. However, there is no
data related to aggressive periodontitis patients. In this study, we aimed to
determine the prevalence of H. pylori
in subgingival plaque samples of chronic, aggressive periodontitis and
gingivitis patients and to increase the awareness of the patients for gastric
problems.

Materials
and Methods: This study included 155 patients (61 with gingivitis,
60 with chronic periodontitis, and 34 with aggressive periodontitis) who did
not have gastric disease symptom and did not use antibiotics in the last 3
months. The subgingival plaque samples were taken using sterile paper points.
The existence of H. pylori, A. actinomycetemcomitans,
and P. gingivalis
was detected by RT-PCR.

Results: H. pylori was not detected in any groups
at the end of microbiological analysis.
However, a high occurrence of A. actinomycetemcomitans (97.1%) and P. gingivalis
(100%) was observed in the aggressive periodontitis group. However, A. actinomycetemcomitans
and P. gingivalis were found in 30% and 21.7% of patients,
respectively, with chronic periodontitis. A.
actinomycetemcomitans and P. gingivalis
were found in 24.6% of patients in the gingivitis group.

Conclusions: H. pylori were not detected in samples, indicating that subgingival plaque may not
be a primary reservoir for this bacterium.
Les ancêtres au prisme des pommes de terre non domestiquées. Une perspective andine
Authors: Hall Ingrid 
Published: April 2018

Les pommes de terre ont une âme dans les Andes. Il y a des « pommes de terre (du) cadavre » (aya papa), des « pommes de terre des mauvais-morts » (papa de losgentiles), lesquelles ont en commun de n’être pas domestiquées. Il y a aussi des pommes de terre déshydratées (chuño) qui sont presque mortes. Que nous enseigne ceci sur la façon dont les morts, pour les populations des communautés andines, participent encore de la vie ? Voici la question qui va guider cet article. Les conceptions sur la vie et la mort sont ancrées dans un ensemble de pratiques qui débordent le monde des humains, dans une logique pratique et productive qui leur donne sens. Selon ces conceptions, la mort est étroitement associée à la fertilité, à la force-vitale qui anime plantes et individus et ne disparaît pas purement et simplement après la mort mais continue à circuler. Il s’agit là d’un point central de la conception des personnes et du monde dans les Andes. Cet article repose sur des références bibliographiques issues tant de l’agronomie que de l’ethnologie et portant sur l’aire andine, qui sont complétées et éclairées par des données portant sur la région de Cusco (Pérou), lesquelles comprennent des données ethnographiques de première main.
Transcultural Music-Making in Contemporary Music Ensembles: Five Approaches in Germany, the Netherlands, Uzbekistan and Turkey
Authors: Heldt Katja 
Published: April 2018

The present article describes the approaches of five ensembles specialized in transcultural music-making in the context of contemporary music in Germany, the Netherlands, Uzbekistan and Turkey. While facing similar underlying conceptual and practical challenges in the process of combining different musical traditions and cultural backgrounds, such as the question of how to merge oral and notated traditions, tuning systems or musical perceptions, and their presentational performance practices, each ensemble suggests different strategies of implementation, depending on their political, historical and geographical circumstances.The article examines the way in which music derives representational functions within processes of affiliation, delimitation, representation and identity construction.
L’interculturalisme à travers le filtre cognitif : comment Gilles Tremblay recompose le gamelan dans Oralléluiants
Authors: Goldman Jonathan 
Published: April 2018

Dans un article consacré à l’impact bien connu du gamelan sur le langage musical de Claude Debussy, Nicholas Cook propose une interprétation de l’oeuvre du compositeur français qui navigue entre une perspective qui prétend que le gamelan a eu une valeur de « confirmation » de principes déjà acquis et, à l’opposé, une autre qui ne considère les innovations de Debussy que comme de douteuses imitations superficielles d’une culture musicale étrangère. Le présent article est conçu dans la prolongation de l’article de Cook mais orienté vers l’inspiration de la musique javanaise dont témoigne l’oeuvreOralléluiants(1975) de Gilles Tremblay (1932-2017), et tente, à l’instar de celui de Cook, d’aller au-delà d’une opposition entre un pastiche stylistique passablement orientaliste et une approche plus profonde d’« assimilation stylistique » dans la musique du compositeur québécois. L’article propose la notion de « filtre cognitif » pour comprendre la façon dont le gamelan a exercé une influence sur le compositeur sans qu’il ait pour autant affecté d’autres compositeurs de la même façon. Le terme « filtre cognitif » désigne ici toute schématisation de la musique que l’observateur doit à sa formation, son métier, son acculturation, la singularité de sa vie intérieure, etc., et qui représente et ordonne les données de la perception sensorielle permettant ainsi l’appréhension d’une musique jusqu’alors inconnue.
USING RESTORATIVE PRACTICES TO TEACH AND UPHOLD DIGNITY IN AN AMERICAN SCHOOL DISTRICT
Authors: High Anna Jane 
Published: April 2018

The protection and promotion of dignity is a foundational objective of restorative justice. Dignity-enhancing restorative justice practices, which are rooted in the traditional practices of Indigenous people groups, have been widely adopted in schools reactively, as a response to specific infractions. A growing number of schools are adopting restorative practices proactively, with a view to preventing misbehaviour by improving climate and strengthening relationships. This report from the Evanston / Skokie School District (K-8) in Illinois explores a cost-effective restorative practice implementation plan that focuses on volunteers and teachers partnering to introduce one key proactive practice, sharing circles, to classrooms. Using Donna Hicks’ “essential elements of dignity” as a framework, I argue that restorative circle initiatives are a simple and effective means of transforming school communities by acknowledging, promoting and honouring the dignity of students.
Rare patterns of dorsal puncture inPterostichus oblongopunctatus(Coleoptera: Carabidae)
Authors: Schwerk Axel , Jaskuła Radomir 
Published: April 2018

BackgroundThe carabid beetle speciesPterostichus oblongopunctatusis common in different types of forests in Poland and Europe. With respect to this species, some unclarities exist concerning the morphological feature of punctures on the elytra.P. oblongopunctatushas dorsal pits in the third interval of the elytra, the available identification keys, however, provide inconsistent information concerning the puncture in other intervals. During long-term studies at different study sites in Poland, the first author rarely but regularly discovered individuals with unusual dorsal puncture patterns, i.e., pits in the fifth and even in the seventh interval of the elytra. Since such rare patterns might be connected with special habitat characteristics, and thus have a potential as an indicator, the aim of the study was to test if they are connected with specific subpopulations (interaction groups), if they are related to the sex or size of the beetles, and if they are related to specific habitat conditions.Material and MethodsWe counted the pits on the elytra, determined the sex, and measured the length of the right elytron of individuals ofP. oblongopunctatuscollected at numerous study sites located within the borders of the Regional Directory of National Forests in Piła (Western Poland) over the period 2014–2016.ResultsAltogether, 1,058 individuals ofP. oblongopunctatuswere subjected to statistical analysis. Almost 19% of the individuals had a dorsal puncture in the fifth interval of the elytra and about 0.7% had a dorsal puncture in the seventh interval of the elytra. In 2014 and 2015, significantly more females exhibited such unusual patterns of dorsal puncture than males. Even if not statistically significant, in 2016 also relatively more females showed such a pattern. Neither males nor females of the analysed individuals with usual puncture patterns showed a significant difference in the length of the right elytron from those with unusual puncture patterns, and neither for males nor for females a significant correlation of the percentage share of the individuals with unusual puncture patterns with the age of the study sites could be detected. However, both males and females with unusual patterns had more dorsal pits than those without. Moreover, males as well as females showed in all those years a trend that the individuals with unusual patterns have more pits in the third interval of the elytra.DiscussionThe results indicate that females are more likely to exhibit unusual patterns. Since individuals ofP. oblongopunctatuswith a higher number of pits on the elytra are supposed to prevail in more wet habitats, such patterns might be related to moisture conditions. The possibility of pits in the seventh interval of the elytra should be added to identification keys.
Risks from Climate Extremes Change Differently from 1.5°C to 2.0°C Depending on Rarity

Published: April 2018

AbstractParties to the United Nations Framework Convention on Climate Change have agreed to hold the “increase in global average temperature to well below 2°C above preindustrial levels and to pursue efforts to limit the temperature increase to 1.5°C.” Comparison of the costs and benefits for different warming limits requires an understanding of how risks vary between warming limits. As changes in risk are often associated with changes in exposure due to projected changes in local or regional climate extremes, we analyze differences in the risks of extreme daily temperatures and extreme daily precipitation amounts under different warming limits. We show that global warming of 2°C would result in substantially larger changes in the probabilities of the extreme events than global warming of 1.5°C. For example, over the global land area, the probability of a warm extreme that occurs once every 20 years on average in the current climate is projected to increase 130% and 340% at the 1.5°C and 2.0°C warming levels, respectively (median values). Moreover, the relative changes in probability are larger for rarer, more extreme events, implying that risk assessments need to carefully consider the extreme event thresholds at which vulnerabilities occur.
Forbidden Fruit: Dominance Relationships and the Control of Shoot Architecture
Authors: Walker Catriona H. , Bennett Tom 
Published: April 2018

AbstractPlants continually integrate environmental information to make decisions about their development. Correlative controls, in which one part of the plant regulates the growth of another, form an important class of regulatory mechanism, but their study has been neglected, and their molecular basis remains unclear. In this article, we examine the role of negative correlative controls or ‘dominance’ phenomena in the regulation of shoot architecture. Apical dominance, in which actively growing shoot branches inhibit the growth of other branches, is perhaps the most famous example of this. We discuss the recent progress made in understanding the mechanistic basis for apical dominance and three plausible models for shoot branching control. We then use the apical dominance paradigm to explore other dominance phenomena, including seed–seed inhibition (carpic dominance), seed‐to‐meristem inhibition, and the control of maternal senescence by seeds. We propose that apical and carpic dominance may share a common mechanistic basis rooted in auxin transport canalisation. Conversely, we conclude that seed‐to‐meristem inhibition and seed‐driven senescence may not be ‘true’ correlative controls, but rather more complex phenomena in which seed set plays a permissive rather than instructive role. Overall, we attempt to develop a coherent framework for understanding the developmental and regulatory mechanisms that control shoot architecture and provide new insights into the end of flowering, fruiting, and growth.
Demand for ready‐to‐eat cereals with household‐level censored purchase data and nutrition label information: A distance metric approach

Published: April 2018

AbstractWe investigate the demand for ready‐to‐eat (RTE) breakfast cereals in the United States using censored, household‐level purchase data matched with product‐level nutrition data. Instead of using a multi‐equation based approach, we propose an alternative approach that relies on Pinkse, Slade, and Brett's (2002) distance‐metric (DM) method, which is highly practical and less burdensome computationally than some multiple‐equation methods. Among other results, we find that households with children are less price sensitive to cereals with whole grain as the first ingredient and to cereals that contain a higher number of fortified vitamins. In addition, we find that households tend to switch between products with similar fiber content and whole grain content profiles.
Propagations of Airy Beams and Nonlinear Accelerating Optical Beams in Photorefractive Crystals with Asymmetric Nonlocality

Published: April 2018

AbstractThe impact of the asymmetric nonlocal diffusion nonlinearity of Airy beams and nonlinear accelerating beams supported by photorefractive crystals is addressed. It is revealed how the asymmetric nonlocal response alters the evolution of these optical beams. It is found that the evolution of these beams presents a bending action under the influence of the diffusion nonlinearity. It is also shown that nonlinear accelerating beams can exist in photorefractive crystals with asymmetric nonlocality. These accelerating solutions have the same Airy‐like tail, and accelerate along parabolic trajectories. Soliton states are formed in the interaction of both in‐phase and out‐of‐phase Airy beams and nonlinear accelerating beams and also present a bending action because of the action of diffusion nonlinearity.
The Influence of β‐diiminato Ligands on As4 Activation by Cobalt Complexes

Published: April 2018

AbstractIn a systematic study of the activation of As4, three [LCo(tol)] (L=β‐diiminato) complexes have revealed different steric and electronic influences. 2,6‐Diisopropylphenyl (Dipp) and 2,6‐dimethylphenyl (dmp) flanking groups were used, one of the ligands with H backbone substituents (β‐dialdiminate L0) and two with Me substituents (β‐diketiminates L3 and L1). In the reaction with As4, different dinuclear products [(LCo)2As4] (LM=L0 (1), L1 (2), L3 (3)) were isolated, with all showing differently shaped [Co2As4] cores in the solid state: octahedral in 1, prismatic in 2, and asterane‐like in 3. Thermal treatment of 3 leads to the abstraction of one arsenic atom to yield [(L3Co)2As3] (4). All products were comprehensively characterized by single‐crystal X‐ray diffraction, FD‐MS, and 1H NMR spectroscopy. A rational explanation for the different reactivity is also proposed and DFT calculations shed light on the nature of the highly flexible [Co2As4] cores.
Is the Pelvis Sexually Dimorphic in Turtles?
Authors: Cordero Gerardo A. 
Published: April 2018

ABSTRACTVariation in the pelvis is intrinsically linked to life history evolution. This is perhaps best exemplified by sexually dimorphic pelvic variation in bipedal primates. Yet, whether this trend is applicable to other taxa is unclear. Using turtle anatomy as a model, I tested the hypothesis that the pelvis is also sexually dimorphic in egg‐laying tetrapods. I sampled a natural turtle population with female‐biased sexual size dimorphism (i.e., larger females). I show that the area of the egg canal (pelvic aperture) is greater in females. Morphological differences between sexes were predicted by body size, such that skeletal shape deformation of the female ilium increased proportionally with pelvic aperture area. These results suggest that sexual pelvic dimorphism might be indirectly maintained by selection for large female size, consistent with the pelvic constraint hypothesis in reptiles. However, subsampling of similarly sized individuals revealed that pelvic aperture area and shape may vary in disproportion to body size. Comparisons of pelvic ontogenetic trajectories across multiple lineages are needed to clarify the occurrence of sexual pelvic dimorphism in turtles and other egg‐laying tetrapods. My findings provide impetus to further explore how sex‐specific functional demands influence the architecture of the pelvic girdle. Anat Rec, 2018. © 2018 Wiley Periodicals, Inc.
Morphology of a Hidden Tube: Resin Injection and CT Scanning Reveal the Three‐dimensional Structure of the Spiracle in the Japanese Bullhead Shark Heterodontus japonicus (Chondrichthyes; Heterodontiformes; Heterodontidae)

ABSTRACTThe spiracle of elasmobranchs (sharks, skates, and rays) is a gill‐slit‐derived tube located behind the eye. Its inner structure was well studied in the late nineteenth to early twentieth century, but its entire morphology has rarely been characterized and is poorly understood. The present study shows the three‐dimensional morphology of the spiracular tube for the first time, using resin injection and CT scanning, in the Japanese bullhead shark. The spiracular tube is characterized by the presence of two caeca (dorsal and ventral spiracular caeca) on the medial wall of the spiracular tube and the presence of a pseudobranch on the anterior wall. This study provides a basis for further studies on the morphological diversity, function, and evolution of spiracles in elasmobranch fishes. Anat Rec, 2018. © 2018 Wiley Periodicals, Inc.
