Condition contemporaine de la filiation et lien intersubjectif
Authors: Arènes Jacques
Published: June 2016

En s’appuyant sur une réflexion d’anthropologie culturelle informée par la psychanalyse, l’auteur analyse la polysémie du thème de la filiation, en le distinguant d’abord comme une condition « partageable » – le fils ou la fille se découvre alors comme frère ou sœur – puis en décrivant les articulations qui le constituent. En utilisant des exemples cliniques et littéraires, l’article élabore une théorie de la filiation tenant compte de ses dimensions topique et énergétique, proposant l’hypothèse de la filiation comme forme dynamique évoluant dans le temps, à l’interface de l’intrapsychique et de l’intersubjectif, et rendant compte du versant vertical du lien.
L’identité sexuée : une construction intersubjective ?
Authors: Chapellon Sébastien , Gontier Élisabeth
Published: June 2016

Des processus intersubjectifs sont à l’œuvre dans le développement d’un aspect essentiel de la subjectivation : le sentiment d’être fille ou garçon. Les auteurs montrent que l’investissement par l’enfant de son sexe est d’abord le fruit du lien à l’autre et à son inconscient. La construction de l’identité sexuée dépend des interactions qui relient le sujet à son milieu familial et à son environnement social.
L’homme transsexuel, sa femme et leur enfant
Authors: Rosenblum Ouriel
Published: June 2016

L’auteur aborde l’accès à la parentalité d’un couple composé d’un homme, ancienne femme, et de sa compagne dans le cadre légal d’un centre de biologie de la reproduction. Une personne transsexuelle féminin vers masculin ( Female to Male, FtM ) est une personne qui, ayant un corps de femme, se sent une identité d’homme et demande une réassignation de son sexe, par une transformation hormono-chirurgicale et un changement d’état-civil. Ensuite, cette personne peut jouir de toutes les prérogatives liées à son nouveau sexe. Ainsi, la loi française lui reconnaît la possibilité de se marier avec une femme. Le couple étant stérile par absence de spermatozoïdes chez cet homme, il a le droit de demander une Aide Médicale à la Procréation pour infertilité, comme pour tout autre couple hétérosexuel. L’auteur tente de saisir la spécificité de ces couples, tant dans leur choix amoureux que dans leur parcours qui les amène à devenir de futurs parents. Pour les thérapeutes de couple et de famille dans une perspective psychanalytique, il apparaît fondamental d’accompagner ces sujets désireux de fonder une famille, dans un souci leur permettant d’être des acteurs à part entière des processus de transmission.
Violences collectives dans l’histoire familiale : une source de subjectivation
Authors: Burksaityte Goda , Konicheckis Alberto
Published: June 2016

L’intersubjectif familial, soumis aux violences collectives, peut s’éloigner d’un destin pathologique lorsqu’il œuvre à une transformation groupale de ces expériences brutes. Par ce biais, il atténue la charge des violences véhiculées dans les transmissions familiales. Ainsi s’ouvre la voie du processus de leur appropriation individuelle. Le destin d’une famille lituanienne, rencontrée lors d’une recherche portant sur les familles ayant subi les déportations en Sibérie, sert de fil conducteur à la réflexion. Il s’agit d’une famille issue de deux lignées de déportés qui se rencontrent sur les lieux d’un exil de 12 ans. Le parcours de cette famille, longuement soumise au système totalitaire, témoigne de la façon dont un groupe familial procède à une co-création des espaces de métabolisation et de commémoration des violences subies, permettant ainsi à ses membres d’élaborer leur histoire familiale douloureuse. Cette dernière devient source de subjectivation.
Les liens intersubjectifs familiaux comme auxiliaires de la constitution subjective : Illustration par la « co-maternité »
Authors: Mokdad Zmitri Meriem
Published: June 2016

Le constat d’une intersubjectivité qui alimente la subjectivation n’est plus à démontrer bien que les tergiversations aient été longues et nombreuses avant que ne lui soit faite une place au sein de la métapsychologie psychanalytique. Le travail au sein de dispositifs pluriels, couples et familles en l’occurrence, permet d’en relever l’évidence. Mais, comme l’enveloppe psychique familiale est en perpétuelle négociation avec son homologue culturel, l’examen des configurations de liens intersubjectifs imprégnés par la culture peut informer sur les processus et mécanismes par lesquels l’intersubjectivité œuvre à fluidifier la constitution subjective de sujets en devenir dans les espaces intra-, inter- et transsubjectif. La « co-maternité », configuration récurremment observée chez des couples et familles tunisiens, est ici décrite et analysée, vignette clinique à l’appui, dans la finalité de plaider cet argumentaire.
Du viol comme répétition transgénérationnelle à la maternité comme tentative de réparation
Authors: Mazoyer Anne-Valérie , Roques Marjorie , Joubert Christiane
Published: June 2016

Dans le viol, la cruauté et la menace utilisées à visée d’asservissement et à des fins de jouissance renforcent l’effraction du sexuel qui s’apparente à une rencontre avec la mort. À partir d’une situation clinique, les auteurs interrogent le devenir de ces maternités, alors même qu’elles surviennent après un viol et que la préoccupation maternelle primaire serait troublée dans cette conception traumatique. Chez une femme rencontrée, est repérée la fonction de réparation de ses deux maternités qui s’inscrivent dans le mandat de consoler des traumatismes divers (maltraitance familiale, conception honteuse, répétition transgénérationnelle). Les auteurs questionnent aussi le cadre de l’expertise clinique comme modalité d’expression de pans traumatiques non reconnus.
Cette université est-elle durable ? Contribution des sciences des réseaux à une cartographie du complexe
Authors: Jollivet Pascal , Vallet Flore
Published: June 2016

La conjonction de la complexité intrinsèque des initiatives en Développement durable (DD) (multi-dimensionnalité, dialogiques) et du déluge de données contemporain (Big Data) requiert de nouveaux concepts et outils d’exploration et d’aide à la décision. En combinant des approches en termes de réseaux des parties prenantes issues des Sciences humaines et sociales (SHS) avec d’autres telles que les sciences des réseaux provenant des Sciences et techniques de l’ingénieur (STI), nous élaborons des cartes de portefeuilles de projets et initiatives DD structurées par des réseaux de relations (« sociales » et « sémantiques »). Des « stratégies du complexe » basées sur des diagnostics et préconisations instrumentés, pouvant révéler des disfonctionnements et/ou des opportunités dans des structures de réseau complexe, sont alors proposées. L’étude de cas porte sur une université française et son écosystème proche.
A cognitive approach to complement support practices for the maturation of eco-innovations
Authors: Real Marion , Lizarralde Iban , Legardeur Jérémy , Tyl Benjamin , Millet Dominique
Published: June 2016

Au cours de ces dernières années, beaucoup d’initiatives, à des niveaux différents de la société ont vu le jour aspirant à une plus forte soutenabilité dans nos modes de vie. Au niveau de l’entreprise, le développement de tels projets, appelés « éco-innovants » entraîne fréquemment un besoin de rupture avec les pratiques existantes au sein de l’entreprise et un niveau d’incertitude fort dans les phases amont des projets. Pour favoriser et impulser le développement de projets éco-innovants, l’entreprise s’entoure fréquemment de structures externes (organismes d’accompagnement, experts, coachs, consultants, formateurs, chercheurs) pour aider à structurer et à expertiser les projets. Un des enjeux de l’accompagnement de la maturation des idées est de créer un environnement favorable à la minimisation des blocages cognitifs au sein des projets de sorte à leur laisser la possibilité d’explorer des solutions alternatives pour leur projet. Cette étude s’appuie sur l’analyse de trois cas de projets éco-innovants suivi dans le cadre d’une recherche intervention au sein d’un organisme d’accompagnement. Elle a pour but de mieux caractériser la maturation des éco-innovations et les phénomènes cognitifs en jeu lors de cette activité dans la perspective d’une amélioration des pratiques d’accompagnement. Deux types de fixations collectives, respectivement sur les modes de construction du réseau de parties prenantes et sur la gestion du potentiel de soutenabilité, sont détaillés. Un cadre opérationnel est proposé en conclusion aux acteurs d’accompagnements pour aider les groupes projets à adopter une attitude créative et réflexive lors de la maturation des concepts éco-innovants.

Published: June 2016

L’objet de cet article est d’étudier un réseau de « petit monde » dans le but d’améliorer sa densité de communications et, par conséquent, sa complexité, en adaptant la méthode Future Search de résolution de problèmes en grand groupe, proposée par Weisbord et Janoff (1995). Pour cette étude, nous avons choisi deux classes d’étudiants universitaires, devant réaliser un projet exigeant la participation de chacun. Avant le projet puis trois mois plus tard, les étudiants ont répondu à un questionnaire sur la fréquence de leurs contacts et de leur travail avec les autres étudiants inscrits à l’université. Les résultats montrent que la réalisation d’un projet collaboratif, en utilisant la technique de résolution de problèmes en grand groupe, a développé un réseau de petit monde et s’est révélé une innovation dans le contexte de l’enseignement supérieur.
A descriptive sensory analysis of honeybee drone brood from Denmark and Norway
Authors: Evans J. , Müller A. , Jensen A.B. , Dahle B. , Flore R. , Eilenberg J. , Frøst M.B.
Published: June 2016

Honeybee (Apis mellifera) brood is enjoyed as food in many regions of the world. The Nordic region of Europe is not currently one of them, but it could be. The drone brood in particular constitute an untapped source of delicious, nutritious and potentially sustainable food. Currently, it is removed by many beekeepers as part of a strategy to lower the population of the destructiveVarroamite (Varroa destructor) in the hive, but most often it is disposed of. A descriptive sensory analysis of drone brood was conducted, using larvae and pupae from four hives, three in Denmark and one in Norway, from locations spanning a range of urban/rural and monocultural/polycultural surroundings. Data were collected with a panel of 10 subjects using fast sensory methods, and were analysed with analysis of variance-partial least squares regression. The first dimension accounted for 40% of the variance, and correlated closely with differences in developmental stage between larvae and pupae; the second dimension accounted for 16% of the variance, and most closely grouped samples from three of the locations apart from those of the fourth. Developmental stage was thus found to be the primary determinant of sensory profile, followed by variations in locality, possibly related to local forage. Further studies should investigate the different parameters of sensory profile in more detail to develop a more complex picture of drone brood’s taste and culinary potential – an important part of developing strategies to diversify our food sources and realise certain insects’ ecological, culinary, and economic potential for local food systems.
Multidetection of urinary ochratoxin A, deoxynivalenol and its metabolites: pilot time-course study and risk assessment in Catalonia, Spain
Authors: Vidal A. , Cano-Sancho G. , Marín S. , Ramos A.J. , Sanchis V.
Published: June 2016

The presence of two main mycotoxins, ochratoxin A (OTA) and deoxynivalenol (DON), is widespread in cereal-based foodstuffs marketed in Europe. The objectives of this study were to develop and validate a multi-detection analytical methodology to simultaneously assess the urinary concentrations of OTA, DON and their metabolites, and to apply this methodology in a preliminary follow-up trial in Catalonia (Spain). Hence, an ultra-performance liquid chromatography with tandem mass spectrometry method was developed to simultaneously assess the urinary levels of OTA, DON, deoxynivalenol-3-glucoside (DON-3-glucoside), deoxynivalenol-3-glucuronide (DON-3-glucuronide), 3-acetyldeoxynivalenol (3-ADON) and de-epoxy-deoxynivalenol (DOM-1). Urine mycotoxins levels and food dietary intake were prospectively monitored in a group of volunteers throughout a restriction period followed by a free-diet period. The proposed multi-detection methodology for urinary OTA and DON metabolites was validated, providing suitable recovery, linearity and precision. The results from the pilot trial showed that urinary OTA, DON and its metabolites were detected in most background samples, displaying moderate reductions after the restriction period and subsequently recovering the background levels. Despite the restriction period, some DON metabolites, such as 3-ADON or DOM-1, were still found in urine samples, placing alternative sources of DON exposure other than the ones considered in the study under suspicion. DON and DON-3-glucuronide were significantly associated with consumption of bread, pasta and pastries, while OTA was only associated with consumption of wine and breakfast cereals. The urinary levels of OTA were significantly correlated with plasmatic levels of OTA and ochratoxin α, supporting the results from the multidetection method in urine. The results also showed that the high exposure to DON could be held throughout the time by the same person, exceeding the tolerable daily intake systematically instead of eventually. The estimates of OTA exposure through urine are largely higher than those obtained with the dietary approach. The background levels found in urine revealed that the exposure to DON and OTA could be of concern for the Catalonian population, thus, further studies applying this biomonitoring methodology in a larger sample of Catalonian population are needed to accurately characterise the human health risks at population level.
Mycotoxins in organically versus conventionally produced cereal grains and some other crops in temperate regions
Authors: Brodal G. , Hofgaard I.S. , Eriksen G.S. , Bernhoft A. , Sundheim L.
Published: June 2016

This paper presents peer-reviewed studies comparing the content of deoxynivalenol (DON), HT-2+T-2 toxins, zearalenone (ZEA), nivalenol (NIV), ochratoxin A (OTA) and fumonisins in cereal grains, and patulin (PAT) in apple and apple-based products, produced in organically and conventionally grown crops in temperate regions. Some of the studies are based on data from controlled field trials, however, most are farm surveys and some are food basket surveys. Almost half of the studies focused on DON in cereals. The majority of these studies found no significant difference in DON content in grain from the two farming systems, but several studies showed lower DON content in organically than in conventionally produced cereals. A number of the investigations reported low DON levels in grain, far below the EU limits for food. Many authors suggested that weather conditions, years, locations, tillage practice and crop rotation are more important for the development of DON than the type of farming. Organically produced oats contained mainly lower levels of HT-2+T-2 toxins than conventionally produced oats. Most studies on ZEA reported no differences between farming systems, or lower concentrations in organically produced grain. For the other mycotoxins in cereals, mainly low levels and no differences between the two farming systems were reported. Some studies showed higher PAT contamination in organically than in conventionally produced apple and apple products. The difference may be due to more efficient disease control in conventional orchards. It cannot be concluded that any of the two farming systems increases the risk of mycotoxin contamination. Despite no use of fungicides, an organic system appears generally able to maintain mycotoxin contamination at low levels. More systematic comparisons from scientifically controlled field trials and surveys are needed to clarify if there are differences in the risk of mycotoxin contamination between organically and conventionally produced crops.

Sustaining Nursing and Midwifery Grand Rounds in a Regional Australian Health Service
Authors: Smyth Wendy , Abernethy Gail
Published: June 2016

This article reports the success, or otherwise, of strategies implemented to sustain nursing grand rounds in a large regional health service in North Queensland, Australia. Nursing grand rounds had been introduced in late 2010 to increase nurses' engagement with research and evidence-based practice. Although the format, topics, and purpose of grand rounds have changed, attendees continue to positively evaluate each presentation. However, after 5 years, the initiative has expanded and somewhat modified its focus. This article describes these changes and proposes options for the future progression of this professional development activity.

Teaching Critical Thinking Using Reflective Journaling in a Nursing Fellowship Program
Authors: Zori Susan
Published: June 2016

Critical thinking (CT) is considered to be foundational for the development of RN clinical reasoning. Reflective journaling has been used as an educational strategy to support the development of CT. This project's purpose was to explore how using reflective journaling about CT dispositions with RNs in a fellowship program might influence RN's use of CT dispositions. This descriptive, qualitative study used content analysis as the method to analyze journal entries focused on seven CT dispositions: inquisitiveness, systematicity, open mindedness, analyticity, truth seeking, CT maturity, and CT confidence written by RNs in the first 7 weeks of their fellowship program. Based on the content analysis of journal entries, two major descriptive themes emerged: Development of Critical Thinking Is a Process That Develops During a Period of Time, and Purposefully Engaging Critical Thinking Dispositions May Help Prevent Negative Patient Outcomes. The purposeful use of CT dispositions as described in the journal entries also helped to guide the RN's individual learning.

Short-Term Global Experiences: Reflections, Themes, and Implications
Authors: Ryan-Krause Patricia
Published: June 2016

Background:

Many schools of nursing offer international service-learning opportunities. Research on these experiences describes benefits to students, but the importance of building long-term relationships and community health capacity is seldom addressed.

Method:

The written posttravel reflections of 89 advanced practice nursing students, following brief global experiences over 9 years in developing areas, were analyzed to identify themes and implications for future work.

Results:

Analysis of student reflections produced four themes and 13 subthemes. Students described accomplishments and challenges. Improvements were noted in clinical skills and linguistic abilities. Challenges included ethical issues of undermining the value of local providers, obstacles to appropriate follow-up care, and disruption of community life. An ongoing project that responds to community needs for education and training was offered as a better means to improving health.

Conclusion:

Global health service-learning experiences can be beneficial to both students and communities, especially if imbedded in structured academic courses designed to include long-term solidarity with the community and the development of health capacity and ethical nursing practices.

Context-Based Pedagogy: A Framework From Experience
Authors: Kantar Lina D.
Published: June 2016

Background:

Attempts to transform teaching practice are inadvertently subjected to several hurdles, mostly attributed to the lack of a guiding framework. This study aimed at unraveling the conceptual underpinnings of the context-based pedagogy, being perceived the pedagogy that prepares professionals for future practice.

Method:

Through focus group interviews, data were collected from 16 nursing students who had case studies as the main instructional format in three major courses. The participants were divided into three focus groups, and interview questions were based on three educational parameters: the learning environment, instructional format, and instructional process.

Results:

Initial findings revealed an array of classroom activities that characterize each parameter. An in-depth analysis of these activities converged on four concepts: (a) dynamic learning environment, (b) realism, (c) thinking dispositions, and (d) professional formation.

Conclusion:

These concepts improvise a beginning framework for educators and curriculum leaders that can be used to integrate cases in the curriculum and to facilitate the contextualization of knowledge. [

Student-Perceived Influences on Performance During Simulation
Authors: Burbach Beth E. , Thompson Sarah A. , Barnason Susan A. , Wilhelm Susan L. , Kotcherlakota Suhasini , Miller Connie L. , Paulman Paul M.
Published: June 2016

Background:

Understanding the effect of the context of simulation to learning and performance is critical to ensure not only optimal learning but to provide a valid and reliable means to evaluate performance. The purpose of this study is to identify influences on performance from the student perspective and understand the contextual barriers inherent in simulation before using simulation for high-stakes testing.

Method:

This study used a qualitative descriptive design. Senior nursing students (
N
= 29) provided nursing care during simulation. Vocalized thoughts during simulation and reflective debriefing were digitally recorded and transcribed verbatim. Thematic analysis was conducted on transcribed data.

Results:

Student performance during simulation was influenced by anxiety, uncertainty, technological limitations, and experience with the patient condition. Students had few previous simulation-based learning experiences that may have influenced performance.

Conclusions:

More needs to be understood regarding factors affecting simulation performance before pass-or-fail decisions are made using this technology. [

Cooperative Clinical Conferences: Nursing Student Pediatric Clinical Innovation
Authors: Waldron Mia K. , Washington Shari L. , Montague Gay P.
Published: June 2016

Background:

A gap exists between nursing student classrooms (i.e., clinical training) and newly graduated RNs' real-world nursing experiences. The Cooperative Clinical Conference (CCC) was piloted for prelicensure nursing clinical groups as a vehicle to allow students to reflect on their learning and physiology and disease, as it relates to the pediatric patient in the context of the entire plan of care for pediatric patients.

Method:

Participating nursing student clinical groups were allotted 15 to 20 minutes to give group case presentations of de-identified patient scenarios, representative of the patient population on the assigned clinical unit.

Results:

The CCC as a learning opportunity in the clinical area was rated highly on evaluations by faculty and student participants in terms of their achievement of both learning objectives and satisfaction.

Conclusion:

The CCC represented a feasible and acceptable method of enhanced learning and professional development with and for undergraduate nursing students in the pediatric clinical environment. [

Study of recycled concrete aggregate quality and its relationship with recycled concrete compressive strength using database analysis
Authors: González-Taboada I. , González-Fonteboa B. , Martínez-Abella F. , Carro-López D.
Published: June 2016

This work studies the physical and mechanical properties of recycled concrete aggregate (recycled aggregate from concrete waste) and their influence in structural recycled concrete compressive strength. For said purpose, a database has been developed with the experimental results of 152 works selected from over 250 international references. The processed database results indicate that the most sensitive properties of recycled aggregate quality are density and absorption. Moreover, the study analyses how the recycled aggregate (both percentage and quality) and the mixing procedure (pre-soaking or adding extra water) influence the recycled concrete strength of different categories (high or low water to cement ratios). When recycled aggregate absorption is low (under 5%), pre-soaking or adding extra water to avoid loss in workability will negatively affect concrete strength (due to the bleeding effect), whereas with high water absorption this does not occur and both of the aforementioned correcting methods can be accurately employed.
Sibship and Self-Esteem in Children With Asthma
Authors: Polizzi Concetta , Fontana Valentina , Carollo Antonio , Bono Alessandra , Burgio Sofia , Perricone Giovanna
Published: June 2016

This study has explored the valence of sibship that may empower the self-esteem of children with asthma at the interpersonal, environmental control competence, emotionality management, and body-image levels. It has been assumed that the relationship between siblings may have a moderating effect on the negative impact that asthma has on child’s development. Seventy children suffering from chronic asthma have been involved: 40 children with siblings (experimental group) and 30 sibling-free children (control group). The children with asthma have exhibited higher levels of self-esteem in comparison with the sibling-free children. The results of the study, at the clinical significance level, highlight how meaningful could be the involvement of healthy siblings to support the development, and to ease the compliance of children suffering from asthma. The outcomes have confirmed the supportive valence of sibship for the self-esteem of the children with asthma.

Ensiklopedie van die Evangelie van Matteus: Transtekstuele eggo’s
Authors: Van Aarde Andries G.
Published: June 2016

Encyclopaedia of the Gospel of Matthew: Transtextual echoes. This article argues that the Gospel of Matthew should be interpreted as a commentary on Mark in light of Derrida’s notion ‘difference’, Barthes’ understanding of ‘fictional encyclopaedia’ en Gennette’s ‘transtextuality’. However, seeing Matthew as a commentary of Mark (i.e. a text that replaces another) does not exclude the consideration of various other encyclopaedic facets which are transparent in Matthew’s surface structure. This article consists of an explanation of the literary-theoretical concept fictional encyclopaedia and applies this intertextual notion on a variety of aspects in existing Matthean studies. These aspects are, for example, Matthew’s narrative structure, the Matthean Jesus profile as a ‘Mosaic Joshua’ figure and the Jesus’ disciples as potential collaborators of Jesus’ antagonists, namely the Pharisees. This article demonstrates the correlation between Matthew’s beginning (Jesus’ genealogy) and its end (Jesus’ commission of the disciples) against the background of transtextual echoes.

Published: June 2016

Introduction: Limited information is available on the usefulness of the PIMATM analyser in predicting antiretroviral treatment eligibility and outcome in a primary healthcare clinic setting in disadvantaged communities in KwaZulu-Natal, South Africa.Materials and methods: The study was conducted under the eThekwini Health Unit, Durban, KwaZulu-Natal. Comparison of the enumeration of CD4+ T-cells in 268 patients using the PIMATM analyser and the predicate National Health Laboratory Services (NHLS) was undertaken during January to July 2013. Bland-Altman analysis to calculate bias and limits of agreement, precision and levels of clinical misclassification at various CD4+ T-cell count thresholds was performed.Results: There was high precision of the PIMATM control bead cartridges with low and normal CD4+ T-cell counts using three different PIMATM analysers (%CV < 5). Under World Health Organization (WHO) guidelines (≤ 500 cells/mm3), the sensitivity of the PIMATM analyser was 94%, specificity 78% and positive predictive value (PPV) 95%. There were 24 (9%) misclassifications, of which 13 were false-negative in whom the mean bias was 149 CD4+ T-cells/mm3. Most (87%) patients returned for their CD4 test result but only 67% (110/164) of those eligible (≤ 350 cells/mm3) were initiated on antiretroviral therapy (ART) with a time to treatment of 49 days (interquartile range [IQR], 42–64 days).Conclusion: There was adequate agreement between PIMATM analyser and predicate NHLS CD4+ T-cell count enumeration (≤ 500 cells/mm3) in adult HIV-positive individuals. The high PPV, sensitivity and acceptable specificity of the PIMATM analyser technology lend it as a reliable tool in predicting eligibility and rapid linkage to care in ART programmes.Keywords: HIV; Point of Care; PIMATM CD4+ T cell counts; antiretroviral therapy; prediction/eligibility; South Africa

On the Hochschild homology of open Frobenius algebras
Authors: Abbaspour Hossein
Published: June 2016

We prove that the shifted Hochschild homology

HH_*(A,A)[m]

of a symmetric open Frobenius algebra

A

of degree

m

has a natural coBV-algebra structure which is defined at the chain level. As a consequence

HH^*(A,A^\vee)[-m]

is a BV algebra. The underlying coalgebra and algebra structure may not be resp. counital and unital. We also introduce a natural BV-algebra structure on

HH_*(A,A)[m]

which is also defined at the chain level. Hence there is a BV-structure on

HH_*(A,A)[m]

. Moreover we prove that the product and coproduct on

HH_*(A,A)[m]

satisfy the Frobenius compatibility condition i.e.

HH_*(A,A)[m]

is an open Frobenius algebras. If

A

is commutative, we also introduce a natural BV structure on the shifted relative Hochschild homology

\widetilde{HH}_*(A)[m-1]

. We conjecture that the product of this BV structure is identical to the Goresky–Hingston [10] product on the cohomology of free loop spaces when

A

In this paper we will study

n=1

, while for the latter we show that a component of

{\mathrm{Hilb}^n _A}

containing a simple representation is smooth if and only if it only contains simple representations. Under certain conditions, we generalize this last statement to arbitrary 2-Calabi–Yau algebras.

of our theory is a short proof that the modular envelope of the associative operad is the linearization of the terminal operad in the category of non-

\Sigma

modular operads. This gives a succinct description of this object that plays an important rôle in open
string field theory
. We also sketch further perspectives of the presented approach.
Mini-Workshop: Friezes
Authors: Holm Thorsten , Jørgensen Peter , Morier-Genoud Sophie
Published: June 2016

Frieze patterns were introduced in the early 1970s by Coxeter. They are infinite arrays of numbers in which every four neighbouring entries always satisfy the same arithmetic relation. Amazingly, friezes appear in many situations from various areas of mathematics: projective geometry, number theory, algebraic combinatorics, difference equations, integrable systems, representation theory, cluster algebras…

The mini-workshop aimed to gather researchers with diverse fields of expertise to present recent developments and to discuss new directions of investigation and open problems around friezes.

Mini-Workshop: Recent Developments in Statistical Methods with Applications to Genetics and Genomics
Authors: Ionita-Laza Iuliana , Krawczak Michael , Lin Xihong , Nothnagel Michael
Published: June 2016

Recent progress in high-throughput genomic technologies has revolutionized the field of human genetics and promises to lead to important scientific advances. With new improvements in massively parallel biotechnologies, it is becoming increasingly more efficient to generate vast amounts of information at the genomics, transcriptomics, proteomics, metabolomics etc. levels, opening up as yet unexplored opportunities in the search for the genetic causes of complex traits. Despite this tremendous progress in data generation, it remains very challenging to analyze, integrate and interpret these data. The resulting data are high-dimensional and very sparse, and efficient statistical methods are critical in order to extract the rich information contained in these data. The major focus of the mini-workshop, entitled “Recent Developments in Statistical Methods with Applications to Genetics and Genomics”, has been on integrative methods. Relevant research questions included the optimal study design for integrative genomic analyses; appropriate handling and pre-processing of different types of omics data; statistical methods for integration of multiple types of omics data; adjustment for confounding due to latent factors such as cell or tissue heterogeneity; the optimal use of omics data to enhance or make sense of results identified through genetic studies; and statistical and computational strategies for analysis of multiple types of high-dimensional data.

The past 30 years have not only seen substantial progress and lively activity in various areas within convex geometry, e.g., in asymptotic geometric analysis, valuation theory, the

L_p

-Brunn-Minkowski theory and stochastic geometry, but also an increasing amount and variety of applications of convex geometry to other branches of mathematics (and beyond), e.g. to PDEs, statistics, discrete geometry, optimization, or geometric algorithms in computer science. Thus convex geometry is a flourishing and attractive field, which is also reflected by the considerable number of talented young mathematicians at this meeting.

A Double-Edged Sword: High Interest Rates in Capital Control Regimes
Authors: Gudmundsson Gudmundur S. , Zoega Gylfi
Published: June 2016

This paper describes the relationship between central bank interest rates and exchange rates under a capital control regime. Higher interest rates may strengthen the currency by inducing owners of local currency assets not to sell local currency offshore. There is also an effect that goes in the opposite direction: higher interest rates may increase the flow of interest income to foreigners through the current account, making the exchange rate fall. The historical financial crisis in Iceland provides excellent testing grounds for the analysis. Overall, the Icelandic experience does not suggest that cutting interest rates in small steps from a very high level is likely to make a currency depreciate significantly in a capital control regime, but it highlights the importance of effective enforcement of the controls.

Published: June 2016

La demanda de información sobre el transporte de carbono motivó la generación de datos sobre la salida de carbono orgánico en partículas de suelo en suspensión. Se consideraron diferentes usos de suelo: praderas de zacate buffel (PZB), parcelas de cultivo abandonadas (PCA) y el pastizal nativo (PN). Se utilizó la técnica de simulación de lluvia para generar escurrimiento sobre parcelas de escurrimiento (3 x 1 m) para obtener en cada uso de suelo una alícuota de 0.5 L, de la cual se separaron los sedimentos sólidos (suelo y material orgánico) y mediante un análisis por el método de Walkley y Black se determinó el porcentaje de carbono. Se utilizó un diseño experimental de bloques al azar con tres repeticiones para determinar las diferencias en el contenido de carbono (%). Los resultados obtenidos muestran que en el pastizal nativo y en condiciones de humedad inicial se registraron los valores promedio más altos de carbono en los sedimentos en suspensión (3.79 %); mientras que las condiciones de mejor cobertura del suelo en las praderas de zacate buffel y en las parcelas de cultivo abandonadas (1.20 y 1.18 % respectivamente) fueron menores que las pérdidas de carbono ocurridas en el pastizal nativo (3.11 %).

Published: June 2016

La erosión hídrica del suelo es un problema que causa pérdidas económicas significativas, es por eso, que en el presente estudio se planteó como objetivo cuantificar la pérdida de suelo mediante la aplicación de la Ecuación Universal de Pérdida de Suelo Revisada en la subcuenca Agustín Melgar de la Región Hidrológica 36. Se recurrió al uso de un Sistema de Información Geográfica con el fin de obtener parámetros distribuidos de la ecuación estudiada. Los resultados muestran que existen distintos niveles de pérdida de suelo en la cuenca en estudio, que van desde “muy reducida” (pérdidas menores a 5 t·ha-1) a “extrema” (pérdidas mayores de 200 t·ha-1).

Published: June 2016

Los riegos de los cultivos con agua salina inducen detrimentos en la productividad, así como deterioro de los suelos agrícolas. El NaCl es la sal tóxica de mayor importancia que provoca estrés iónico y osmótico en las plantas, con un consecuente esfuerzo mayor para absorber el agua y que afecta su crecimiento. Se realizó un estudio en invernadero cuyo objetivo fue determinar los efectos simbióticos de los hongos micorrízicos arbusculares (HMA) Burize ST® y Micorriza INIFAP® (Rhizophagus intraradices) en los híbridos de sorgo ‘Norteño’ y ‘Gstar 7609’, sometidos a irrigación con tres niveles de agua salina (desalinizada, media y alta, CE = 0.03, 2.30 y 4.54 dS·m-1, respectivamente). Las variables medidas fueron clorofila (SPAD), altura de planta, diámetro de tallo, biomasa aérea y radical, y colonización micorrízica. Con excepción de la colonización que no fue inf luenciada por el nivel de salinidad del agua, los valores de las demás variables decrecieron conforme se incrementó la concentración de sales en el agua. En general los resultados indicaron que se registró mayor crecimiento y rendimiento de biomasa en plantas de sorgo mediante la asociación simbiótica entre el HMA Micorriza INIFAP y el sorgo ‘Norteño’, en los tres niveles de salinidad en el agua de riego.
Increasing the accuracy and temporal resolution of two-filter radon–222 measurements by correcting for the instrument response

Published: June 2016

Abstract. Dual-flow-loop two-filter radon detectors have a slow time response, which can affect the interpretation of their output when making continuous observations of near-surface atmospheric radon concentrations. While concentrations are routinely reported hourly, a calibrated model of detector performance shows that ∼ 40 % of the signal arrives more than an hour after a radon pulse is delivered. After investigating several possible ways to correct for the detector's slow time response, we show that a Bayesian approach using a Markov chain Monte Carlo sampler is an effective method. After deconvolution, the detector's output is redistributed into the appropriate counting interval and a 10 min temporal resolution can be achieved under test conditions when the radon concentration is controlled. In the case of existing archived observations, collected under less ideal conditions, the data can be retrospectively reprocessed at 30 min resolution. In one case study, we demonstrate that a deconvolved radon time series was consistent with the following: measurements from a fast-response carbon dioxide monitor; grab samples from an aircraft; and a simple mixing height model. In another case study, during a period of stable nights and days with well-developed convective boundary layers, a bias of 18 % in the mean daily minimum radon concentration was eliminated by correcting for the instrument response.
