Caring, Cooking, Cleaning – repräsentative Zeitverwendungsmuster von Eltern in Paarbeziehungen
Authors: Klünder Nina , Meier-Gräwe Uta 
Published: March 2018

As a result of the increasing labor force participation of mothers, this article questions how twoparent households divide the housework activities of caring, cooking and cleaning. Therefore three types of couples with different labor force participations were formed: Dual-earner couples, couples with additional female income and malebreadwinner couples. The time use for the mentioned activities was examined with a secondary analysis based on the German representative time use surveys of 2012/2013 and 2001/2002. The analysis showed that fulltime mothers spent the lowest amount of time for caring, cooking and cleaning. However, unemployed mothers spent the most time for these activities. Within a decade – from 2001/2002 to 2012/2013 – all mothers have reduced their time spent on household activities. Meanwhile, all parents in 2012/2013 take noticeably more time for child care. Regardless of the mother’s labor force participation, mothers still spent more time for caring, cooking and cleaning, especially on weekdays. Additionally, the everyday housework is divided by gender. Only on weekends, couples with employed mothers shared the care-work almost egalitarian.
Zusammenfassung
Vor dem Hintergrund der steigenden Erwerbstätigkeit von Müttern geht dieser Beitrag der Frage nach, wie Eltern in Paarbeziehungen die Haushaltsbereiche Betreuung, Beköstigung sowie Wohnungs- und Wäschereinigung untereinander aufteilen. Dazu werden drei Paartypen mit unterschiedlichem Erwerbsumfang gebildet: Zweiverdiener- Paare, Paare mit weiblichem Zuverdienst sowie Paare mit männlichem Familienernährer. Deren Zeitverwendung für die genannten Tätigkeiten wird mithilfe der repräsentativen Zeitverwendungserhebung 2012/2013 und 2001/2002 sekundäranalytisch untersucht. Die Analyse zeigt, dass vollzeiterwerbstätige Mütter täglich am wenigsten Zeit für die drei genannten Arbeitsbereiche im Haushalt aufwenden, nicht erwerbstätige Mütter hingegen am meisten. Innerhalb einer Dekade – von 2001/2002 bis 2012/2013 – haben alle untersuchten Mütter ihre Zeitverwendung für hauswirtschaftliche Tätigkeitsfelder reduziert, zeitgleich nehmen sich Eltern 2012/2013 deutlich mehr Zeit für Betreuungsaufgaben. Unabhängig des Erwerbsumfangs der Mutter ist die Arbeit des Alltags nach wie vor, besonders werktags, weiblich konnotiert und somit geschlechtsdifferenzierend aufgeteilt. Nur am Wochenende zeigt sich in Paaren mit erwerbstätiger Mutter bei der Betreuung eine annährend egalitäre Arbeitsteilung.

Authors: Kosulin Karin , Lam Elena , Heim Albert , Dobner Thomas , Rodríguez Estefanía 
Published: March 2018

Background Human adenoviral (HAdV) infections are usually mild and self-limited, however, some infections from species A, B, C, D and E, can cause severe illnesses, which have raised public health concerns over the past few years. Current available antiviral therapies have limited efficacy and severe toxicity; therefore, finding new targets for specific anti-adenoviral drug design is urgently needed. Our previous work showed that the small molecule compound, HBX, inhibits HAdV type 5 (species C, HAdV-C5) replication and oncogenic transformation through inhibition of the cellular pro-viral factor ubiquitin-specific protease 7 (USP7). Here, we have tested the ability of HBX to inhibit other HAdV species, as well as different clinical isolates that are the cause of severe infections. Methods We treated HAdV-infected A549 cells with different concentrations of HBX and analysed the antiviral efficacy of the drug by determining the half maximal inhibitory concentration (IC50) necessary to decrease both viral genome copies and virus progeny production at different time points after infection. Results In addition to its effect on HAdV-C5, HBX was able to significantly inhibit virus genome replication and progeny release of all adenovirus types tested, with the exception of types 12 and 31, from species A. Of note, clinical isolates were more sensitive to HBX treatment than their prototype strains. Conclusions These results point to HBX as a promising broad-spectrum anti-adenoviral drug, opening new opportunities to prevent severe adenoviral infections and to improve their treatment.
Sensitivity of the tropical climate to an interhemispheric thermal gradient: the role of tropical ocean dynamics
Authors: Talento Stefanie , Barreiro Marcelo 
Published: March 2018

Abstract. This study aims to determine the role of the tropical ocean dynamics in the
response of the climate to extratropical thermal forcing. We analyse and
compare the outcomes of coupling an atmospheric general circulation model (AGCM) with two ocean models of different complexity. In the first
configuration the AGCM is coupled with a slab ocean model while in the second
a reduced gravity ocean (RGO) model is additionally coupled in the tropical
region. We find that the imposition of extratropical thermal forcing (warming in the Northern Hemisphere and cooling in the Southern Hemisphere
with zero global mean) produces, in terms of annual means, a weaker response
when the RGO is coupled, thus indicating that the tropical ocean dynamics
oppose the incoming remote signal. On the other hand, while the slab ocean
coupling does not produce significant changes to the equatorial Pacific sea
surface temperature (SST) seasonal cycle, the RGO configuration generates
strong warming in the central-eastern basin from April to August
balanced by cooling during the rest of the year, strengthening the seasonal
cycle in the eastern portion of the basin. We hypothesize that such changes
are possible via the dynamical effect that zonal wind stress has on the
thermocline depth. We also find that the imposed extratropical pattern
affects El Niño–Southern Oscillation, weakening its amplitude and
low-frequency behaviour.
Free-flow wind speed from a blade-mounted flow sensor
Authors: Pedersen Mads Mølgaard , Larsen Torben Juul , Madsen Helge Aagaard , Andersen Søren Juhl 
Published: March 2018

Abstract. This paper presents a method for obtaining
the free-inflow velocities
from a 3-D flow sensor mounted on the blade of a wind turbine. From its position on the rotating blade, e.g. one-third from the tip,
a blade-mounted flow sensor (BMFS) is able to provide valuable
information about the turbulent sheared inflow in different regions of
the rotor. At the rotor, however, the inflow is affected by the wind
turbine, and in most cases the wind of interest is the inflow that the
wind turbine is exposed to, i.e. the free-inflow velocities. The current method applies a combination of aerodynamic models and
procedures to estimate the induced velocities, i.e. the disturbance of
the flow field caused by the wind turbine. These velocities are
subtracted from the flow velocities measured by the BMFS to obtain the
free-inflow velocities. Aeroelastic codes, like HAWC2, typically use
a similar approach to calculate the induction, but they use it for the
reversed process, i.e. they add the induction to the free inflow to get
the flow velocities at the blades, which are required to calculate the
resulting aerodynamic forces. The aerodynamic models included in the current method comprise models
based on blade element momentum (BEM) for axial and tangential
induction, a radial induction model and tip loss correction, and
models for skew and dynamic inflow. It is shown that the method is able to calculate the free-inflow
velocities with high accuracy when applied to aeroelastic HAWC2
simulations with a stiff structural model while some deviations are seen
in simulations with a flexible structure. Furthermore, the method is tested on simulations performed by a flexible
structural model coupled with a large-eddy simulation (LES) flow
solver. The results of this higher-fidelity verification confirm the
HAWC2-based conclusion.

Published: March 2018

Content of free and total endogenous sulfur dioxide were evaluated by classical iodometric titration in must, during winemaking processes and in bio-wine. No exogenous sulfur dioxide was added in any technological operations to simplify the evaluations. In addition, the results were corrected on the content of reductons (total content of reducing substances). The results confirmed formation of endogenous sulfur dioxide from sulfur containing substances (sulfur containing amino acids etc.) in both experiments. Microbial sulfur dioxide is preferably bound to carbonyl substances. Only minor part is present in the free (active) form of the sulfur dioxide. In addition, total content of polyphenols (TPC) and total antioxidant capacity (TAC) were determined by spectrophotometry at the same time. A procedure OIV-MA-AS323-O4B: R 2009 was used. Contents of "free" and "total" sulfur dioxide (with/without correction on contents of reductons) and total content of reductones were determined after complexing the sulfur dioxide with formaldehyde. A standard spectrophotometric method using Folin-Ciocalteu reagent was applied for determination of total content of polyphenolics (TPC) at 765 nm after 60 min incubation. The results were expressed as tannin equivalents (in mg.L-1). A standard DPPH (2,2´-difenyl-1-picrylhydrazyl dissolved in methanol) spectrophotometric method was applied for determination of total antioxidant capacity (TAC) at 515 nm. Depletion of the color intensity was measured after 60 min incubation against blank (methanol) and absorbance decrease Δ(A) = (A0 - A1)/A0 was calculated and used for construction of calibration curve. The TAC values were expressed as ascorbic acid concentrations (in mg.L-1).

Wine is considered to be a significant alcoholic beverage, which is the result of fermentation of grape must or mash. Wine is a must when the substances contained in it play a major role, which are essential inhibiting water, carbohydrates, acids, minerals, nitrates, polyphenols and aromatics. These biochemical components are an important tracking element in wine evaluation in terms of chemical analyzes. An important parameter of monitoring is polyphenolic substances. Polyphenol substances are identified in plant materials as several thousand pieces with a very diverse structure. However, they have a
common feature up to one or more aromatic rings substituted with hydroxyl groups. These substances may be present in plant material in a small or large amount. The total daily intake of polyphenols is estimated at 1 g. This is a higher intake than antioxidant vitamin intakes and it is confirmed that their antioxidant activity is higher than that of antioxidant vitamins. When monitoring the content of all polyphenols (TPC) in selected samples using a spectrophotometric method, a higher TPC content of red wines against white white wines can be observed. Total antioxidant activity is introduced to compare anti
oxidant effects of different mixtures and is based on the ability to eliminate radicals. Antioxidant activity and effects of polyphenols can be inhibited by the addition of preservatives to wine. The preservative is sulfur dioxide (SO 2), which has antimicrobial and antioxidant effects. This compound is not harmless because it is a strong allergen, blocks bacteria in the digestive tract and prevents the conversion of sugars and alcohol derivatives in the liver by blocking vitamin
B. In the normal life, SO2 is consumed under the E 220 mark. The aim of this work is to monitor the change in the total polyphenols content related to free and bound sulfur dioxide (SO2) content using accredited OIV-MA-AS323-O4B: R, 2009 samples in wine samples. Comparison of organic wines and wines produced by classical, it was found that organic wine have a higher content of biologically active substances and have a strong correlation factor TAA - total SO2 (r = 0.77 to 0.91), depending on the wine variety.

ABSTRACTThe objective of the present study was to evaluate the effect of a hydrocolloid dressing on second intention wound healing in cats. Two full-thickness skin wounds, measuring 2 × 2 cm, were created on both sides of the dorsal midline of 10 cats; bilaterally, one randomly selected wound was bandaged with a hydrocolloid dressing and the second one (control) with a semiocclusive pad. Subjective clinical evaluation of granulation tissue formation, of the quantity and nature of wound exudate, and planimetry were performed on the right-side wounds, and histological examination on the left. No significant differences in subjective clinical evaluation or in planimetry were observed between the hydrocolloid-treated wounds and controls. Most wounds had serous or absence of exudate (41.25% and 25%, respectively), whereas purulent exudate was observed in 7.5% of wounds. Edema was significantly increased in the hydrocolloid-treated wounds compared with controls on day 7 but no significant differences in the other histological variables were observed.
Preliminary Assessment of a Novel 14-Day Electrocardiographic Adhesive Patch Monitor in Dogs
Authors: Lichtenberger Jonathan , Meurs Kathryn M. , Côté Etienne 
Published: March 2018

ABSTRACTCardiac arrhythmias often are transient and might not be detected using conventional electrocardiographic (ECG) techniques. The adhesive patch monitor (APM) is a single-lead, lightweight, up to 14-day continuous ambulatory ECG monitor. This study aimed to prospectively assess its usability in four boxer dogs considered either to be healthy or to have arrhythmogenic right ventricular cardiomyopathy. Optimal recording was obtained by placing the APM on the left side of the animal’s thorax, at the fifth intercostal space, slightly dorsal to the costochondral junction, and oriented either vertically or parallel to the long axis of the heart. In three dogs, the APM remained attached for 14 days. One dog removed the APM after 59 hr. Skin irritation was documented in all dogs and resolved spontaneously after removal of the APM. The analyzable time was &gt;93% of the total wear time and recordings provided an unambiguous rhythm diagnosis at rest. Walking, running, or playing caused intermittent motion artifact that could impair ECG interpretation. APM results were comparable to those obtained with 24-hr Holter monitoring. Extended continuous ECG monitoring with the APM is feasible in boxer dogs and provides interpretable recordings.
La gouvernance des territoires : obstacles et opportunités en Acadie
Authors: Guillemot Julie 
Published: March 2018

Ce texte porte sur les obstacles au développement en Acadie, abordés sous l’angle de la gouvernance territoriale et des mobilisations d’acteurs. Considérant que le développement territorial repose sur la capacité qu’ont les acteurs locaux et extralocaux à s’organiser et à se fédérer autour de projets communs, nous traitons, en nous appuyant sur des études de cas, de trois formes d’organisations collectives : les gouvernements locaux, les coopératives et les organisations sans but lucratif (OSBL) à mandat communautaire ou environnemental. Un des aspects le plus frappants des cas étudiés est l’importance des liens entre ces divers organismes. Cependant, plusieurs paramètres de l’aménagement et du développement du territoire échappent aux collectifs locaux. Face aux défis, certains milieux proposent des alternatives. Nous terminons en nous positionnant en faveur d’une plus forte intégration des principes du développement durable dans le cadre des projets territoriaux en Acadie.
La francophonie comme idéologie. Mythes et réalités d’un discours sur la diversité culturelle1
Authors: Klinkenberg Jean-Marie 
Published: March 2018

Le présent article montre comment le concept de francophonie a évolué : renvoyant d’abord à un ensemble défini par un passé colonial, il a fini par désigner une sémiosphère ordonnée autour des valeurs que sont le « dialogue des cultures » et la « diversité culturelle ». Le mot defrancophonea lui aussi connu des évolutions, référant tantôt à des compétences langagières tantôt à une identité. L’étude examine ces ambivalences, comme aussi celle qui affecte la notion de diversité culturelle elle-même. L’article évalue les hypothèques qui pèsent sur le français et l’empêchent d’être authentiquement une langue de la diversité. Il trace enfin diverses pistes qui s’ouvrent aux politiques linguistiques pour faire advenir dans la réalité les valeurs auxquelles prétend la francophonie.
Le projet politique francophone. Nouvelle Babel?
Authors: Pannier Arnaud 
Published: March 2018

Cette étude s’emploie à analyser l’impact de la notion de frontière dans la mise en oeuvre politique du projet francophone.
L’étude procède en deux temps. Elle observe tout d’abord comment la rhétorique propre au discours prononcé dans l’enceinte officielle de l’Organisation internationale de la Francophonie témoigne, à travers les effets d’inclusion et d’exclusion, de conceptions diverses du projet francophone.
L’étude cherche ensuite à démontrer comment l’entreprise francophone se projette dans un espace complexe qui hésite entre respect de la frontière nationale et tentation d’un universalisme fortement imprégné de mythologie. Le mythe de Babel est ici mobilisé pour observer un univers de référence dans lequel se construit l’approche moderne du projet.
L’étude en vient finalement à observer que le statut spécifique de la langue française est porteur de modernité, mais que pour proposer une voie viable, le projet francophone doit explorer de nouveaux territoires, en renonçant aux replis identitaires comme aux visions trop imprégnées d’idéologies.

Authors: Major L. , Warwick P. , Rasmussen I. , Ludvigsen S. , Cook V. 
Published: March 2018

AbstractThis article presents a systematic scoping review of the literature focusing on interactions between classroom dialogue and digital technology. The first review of its type in this area, it both maps extant research and, through a process of thematic synthesis, investigates the role of technology in supporting classroom dialogue. In total, 72 studies (published 2000–2016) are analysed to establish the characteristics of existing evidence and to identify themes. The central intention is to enable researchers and others to access an extensive base of studies, thematically analysed, when developing insights and interpretations in a rapidly changing field of study. The discussion illustrates the interconnectedness of key themes, placing the studies in a methodological and theoretical context and examining challenges for the future.
Vanishing discount approximations in controlled Markov chains with risk-sensitive average criterion
Authors: Cavazos-Cadena Rolando , Hernández-Hernández Daniel 
Published: March 2018

Abstract

This work concerns Markov decision chains on a finite state space. The decision-maker has a constant and nonnull risk sensitivity coefficient, and the performance of a control policy is measured by two different indices, namely, the discounted and average criteria. Motivated by well-known results for the risk-neutral case, the problem of approximating the optimal risk-sensitive average cost in terms of the optimal risk-sensitive discounted value functions is addressed. Under suitable communication assumptions, it is shown that, as the discount factor increases to 1, appropriate normalizations of the optimal discounted value functions converge to the optimal average cost, and to the functional part of the solution of the risk-sensitive average cost optimality equation.
Degree-dependent threshold-based random sequential adsorption on random trees
Authors: Meyfroyt Thomas M. M. 
Published: March 2018

Abstract

We consider a special version of random sequential adsorption (RSA) with nearest-neighbor interaction on infinite tree graphs. In classical RSA, starting with a graph with initially inactive nodes, each of the nodes of the graph is inspected in a random order and is irreversibly activated if none of its nearest neighbors are active yet. We generalize this nearest-neighbor blocking effect to a degree-dependent threshold-based blocking effect. That is, each node of the graph is assumed to have its own degree-dependent threshold and if, upon inspection of a node, the number of active direct neighbors is less than that node's threshold, the node will become irreversibly active. We analyze the activation probability of nodes on an infinite tree graph, given the degree distribution of the tree and the degree-dependent thresholds. We also show how to calculate the correlation between the activity of nodes as a function of their distance. Finally, we propose an algorithm which can be used to solve the inverse problem of determining how to set the degree-dependent thresholds in infinite tree graphs in order to reach some desired activation probabilities.

AbstractWe construct a simple example, surely known to Harry Kesten, of anR-transient Markov chain on a countable state spaceS∪ {δ}, where δ is absorbing. The transition matrixKonSis irreducible and strictly substochastic. We determine the Yaglom limit, that is, the limiting conditional behavior given nonabsorption. Each starting statex∈Sresults in a different Yaglom limit. Each Yaglom limit is anR-1-invariant quasi-stationary distribution, whereRis the convergence parameter ofK. Yaglom limits that depend on the starting state are related to a nontrivialR-1-Martin boundary.
Stretch factor in a planar Poisson–Delaunay triangulation with a large intensity
Authors: Chenavier Nicolas , Devillers Olivier 
Published: March 2018

AbstractLetX:=Xn∪ {(0, 0), (1, 0)}, whereXnis a planar Poisson point process of intensityn. We provide a first nontrivial lower bound for the distance between the expected length of the shortest path between (0, 0) and (1, 0) in the Delaunay triangulation associated withXwhen the intensity ofXngoes to ∞. Simulations indicate that the correct value is about 1.04. We also prove that the expected length of the so-called upper path converges to 35 / 3π2, yielding an upper bound for the expected length of the smallest path.
