Published: November 2016

O processo de aprendizagem relacionado à temática celular exige o uso de linguagem apropriada com analogias que favoreçam o entendimento pelo aluno.O presente trabalho teve como objetivo elaborar jogos educativos para abordagem célula eucarionte animal. A metodologia utilizada baseou-se numa aula teórica abordando células, com ênfase em célula eucariótica. Foi apresentada uma situação-problema e a turma dividida em grupos de dois ou três alunos. Para a elaboração dos jogos os estudantes pesquisaram e estudaram o conteúdo. As atividades foram desenvolvidas durante um trimestre sob orientação de monitores e da professora regente. No primeiro mês, foi elaborada a metodologia e os referenciais que fundamentariam (conceitualmente e pedagogicamente) a estratégia a ser produzida. O segundo mês foi o período da confecção dos materiais. O terceiro mês se constituiu da apresentação e aplicação dos jogos para a turma. Foram feitas avaliações preliminares no ano da confecção e no ano seguinte. Foram produzidos 7 jogos educativos com uma maneira particular de avaliar os competidores. Inicialmente, os alunos desacreditaram da atividade como instrumento de aprendizagem, depois se sentiram estimulados. Observou-se que nos anos de avaliação, no ano de confecção do material (2013) e no ano seguinte (2014) houve aumento significativo na média de notas do conteúdo de célula eucarionte quando comparados ao ano de 2012. A maioria dos alunos considerou que este é um recurso que pode ser usado como ferramenta complementar à aula expositiva. Este trabalho mostrou que os jogos elaborados podem trazer benefícios qualitativos e quantitativos ao ensino de biologia celular.
On the Structure of the Schild Group in Relativity Theory
Authors: Jensen Gerd , Pommerenke Christian 
Published: November 2016

AbstractAlfred Schild has established conditions that Lorentz transformationsmap world-vectors (ct, x, y, z) with integer coordinates onto vectors of the same kind. These transformations are called integral Lorentz transformations.This paper contains supplements to our earlier work with a new focus on group theory. To relate the results to the familiar matrix group nomenclature, we associate Lorentz transformations with matrices in SL(z, ℂ). We consider the lattice of subgroups of the group originated in Schild’s paper and obtain generating sets for the full group and its subgroups.
Sharp isoperimetric inequalities via the ABP method
Authors: Cabré Xavier , Ros-Oton Xavier , Serra Joaquim 
Published: November 2016

Given an arbitrary convex cone of

\mathbb R^n

, we find a geometric class of homogeneous weights for which balls centered at the origin and intersected with the cone are minimizers of the weighted isoperimetric problem in the convex cone. This leads to isoperimetric inequalities with the optimal constant that were unknown even for a sector of the plane. Our result applies to all nonnegative homogeneous weights in

\mathbb R^n

satisfying a concavity condition in the cone. The condition is equivalent to a natural curvature-dimension bound and also to the nonnegativeness of a Bakry-Emery Ricci tensor. Even that our weights are nonradial, still balls are minimizers of the weighted isoperimetric problem. A particular important case is that of monomial weights. Our proof uses the ABP method applied to an appropriate linear Neumann problem.

We also study the anisotropic isoperimetric problem in convex cones for the same class of weights. We prove that the Wulff shape (intersected with the cone) minimizes the anisotropic weighted perimeter under the weighted volume constraint.
As a particular case of our results, we give new proofs of two classical results: the Wulff inequality and the isoperimetric inequality in convex cones of Lions and Pacella.

Published: November 2016

La incorporación de elementos de la cultura de la transparencia de la era del Big Data en el periodismo ha dado como resultado lo que se conoce como periodismo de datos (PD). Objetivos. Al depender de instituciones fuera del periodismo, buscamos determinar hasta qué punto ha afectado la Ley de Transparencia española el desarrollo del PD y cómo ha respondido este sector profesional ante estas afecciones. Metodología. Con entrevistas en profundidad a periodistas de datos examinamos que elementos de la ley afectan el desarrollo del PD. A través de un análisis de contenido en medios con unidades de datos, determinamos como responde el sector ante estos elementos que le afectan. Resultados y conclusiones. El PD en España no ha alcanzado su potencial debido a la insuficiencia e incumplimiento de la ley, por lo que los periodistas han posicionado la transparencia como tema fundamental en la agenda pública
‘I Am Responsible’: Histories of the Intersection of the Guardianship of Unaccompanied Child Refugees and the Australian Border
Authors: Silverstein Jordana 
Published: November 2016

In Australia in 1946, the Immigration (Guardianship of Children) Act was passed. This Act was intended to support the postwar migration to Australia of British children, unaccompanied by their parents, and to provide them with a guardian in Australia—the Immigration Minister. Despite subsequent amendments, this key provision continues. Children who attempt to migrate to Australia unaccompanied by adult family members are subject to the minister’s guardianship. In 1948 Arthur Calwell, the then Minister for Immigration, described himself in parliament as the ‘father’ of these such children. This article focuses on the period from the 1970s to explore what this notion of fatherhood entails. What can it tell us about how children, families and the role of the minister in child refugee policies, have been imagined? I examine how the Act functions as a form of biopolitics, to discipline and regulate intimate relations for child refugees. The article asks how the Act produces a set of historically specific interdependent relationships and highlights the ways successive governments have subordinated concerns for the ‘best interests of the child’ to concerns of the policing of the Australian border.
Physiological responses of coastal and oceanic diatoms to diurnal fluctuations in seawater carbonate chemistry under two CO2 concentrations
Authors: Li Futian , Wu Yaping , Hutchins David A. , Fu Feixue , Gao Kunshan 
Published: November 2016

Abstract. Diel and seasonal fluctuations in seawater carbonate chemistry are common in coastal waters, while in the open-ocean carbonate chemistry is much less variable. In both of these environments, ongoing ocean acidification is being superimposed on the natural dynamics of the carbonate buffer system to influence the physiology of phytoplankton. Here, we show that a coastal Thalassiosira weissflogii isolate and an oceanic diatom, Thalassiosira oceanica, respond differentially to diurnal fluctuating carbonate chemistry in current and ocean acidification (OA) scenarios. A fluctuating carbonate chemistry regime showed positive or negligible effects on physiological performance of the coastal species. In contrast, the oceanic species was significantly negatively affected. The fluctuating regime reduced photosynthetic oxygen evolution rates and enhanced dark respiration rates of T. oceanica under ambient CO2 concentration, while in the OA scenario the fluctuating regime depressed its growth rate, chlorophyll a content, and elemental production rates. These contrasting physiological performances of coastal and oceanic diatoms indicate that they differ in the ability to cope with dynamic pCO2. We propose that, in addition to the ability to cope with light, nutrient, and predation pressure, the ability to acclimate to dynamic carbonate chemistry may act as one determinant of the spatial distribution of diatom species. Habitat-relevant diurnal changes in seawater carbonate chemistry can interact with OA to differentially affect diatoms in coastal and pelagic waters.
OBLIMAP 2.0: a fast climate model–ice sheet model coupler including online embeddable mapping routines
Authors: Reerink Thomas J. , van de Berg Willem Jan , van de Wal Roderik S. W. 
Published: November 2016

Abstract. This paper accompanies the second OBLIMAP open-source release. The package is developed to map climate fields between a general circulation model (GCM) and an ice sheet model (ISM) in both directions by using optimal aligned oblique projections, which minimize distortions. The curvature of the surfaces of the GCM and ISM grid differ, both grids may be irregularly spaced and the ratio of the grids is allowed to differ largely. OBLIMAP's stand-alone version is able to map data sets that differ in various aspects on the same ISM grid. Each grid may either coincide with the surface of a sphere, an ellipsoid or a flat plane, while the grid types might differ. Re-projection of, for example, ISM data sets is also facilitated. This is demonstrated by relevant applications concerning the major ice caps. As the stand-alone version also applies to the reverse mapping direction, it can be used as an offline coupler. Furthermore, OBLIMAP 2.0 is an embeddable GCM–ISM coupler, suited for high-frequency online coupled experiments. A new fast scan method is presented for structured grids as an alternative for the former time-consuming grid search strategy, realising a performance gain of several orders of magnitude and enabling the mapping of high-resolution data sets with a much larger number of grid nodes. Further, a highly flexible masked mapping option is added. The limitation of the fast scan method with respect to unstructured and adaptive grids is discussed together with a possible future parallel Message Passing Interface (MPI) implementation.
Coastal flooding: impact of waves on storm surge during extremes – a case study for the German Bight
Authors: Staneva Joanna , Wahle Kathrin , Koch Wolfgang , Behrens Arno , Fenoglio-Marc Luciana , Stanev Emil V. 
Published: November 2016

Abstract. This study addresses the impact of wind, waves, tidal forcing and baroclinicity on the sea level of the German Bight during extreme storm events. The role of wave-induced processes, tides and baroclinicity is quantified, and the results are compared with in situ measurements and satellite data. A coupled high-resolution modelling system is used to simulate wind waves, the water level and the three-dimensional hydrodynamics. The models used are the wave model WAM and the circulation model GETM. The two-way coupling is performed via the OASIS3-MCT coupler. The effects of wind waves on sea level variability are studied, accounting for wave-dependent stress, wave-breaking parameterization and wave-induced effects on vertical mixing. The analyses of the coupled model results reveal a closer match with observations than for the stand-alone circulation model, especially during the extreme storm Xaver in December 2013. The predicted surge of the coupled model is significantly enhanced during extreme storm events when considering wave–current interaction processes. This wave-dependent approach yields a contribution of more than 30 % in some coastal areas during extreme storm events. The contribution of a fully three-dimensional model compared with a two-dimensional barotropic model showed up to 20 % differences in the water level of the coastal areas of the German Bight during Xaver. The improved skill resulting from the new developments justifies further use of the coupled-wave and three-dimensional circulation models in coastal flooding predictions.
Relationships between snowfall density and solid hydrometeors, based on measured size and fall speed, for snowpack modeling applications

Published: November 2016

Abstract. The initial density of deposited snow is mainly controlled by snowfall hydrometeors. The relationship between snowfall density and hydrometeors has been qualitatively examined by previous researchers; however, a quantitative relationship has not yet been established due to difficulty in parameterizing the hydrometeor characteristics of a snowfall event. Thus, in an earlier study, we developed a new variable, the centre of mass flux distribution (CMF), which we used to describe the main hydrometeors contributing to a snowfall event. The CMF is based on average size and fall speed weighted by the mass flux estimated from all measured hydrometeors in a snowfall event. It provides a quantitative representation of the predominant hydrometeor characteristics of the event. In this study, we examine the relationships between the density of newly fallen snow and predominant snow type as indicated by the CMFs. We measured snowfall density at Nagaoka, Japan, where riming and aggregation are predominant, simultaneously observing the size and fall speed of snowfall hydrometeors, and deduced the predominant hydrometeor characteristics of each snowfall event from their CMFs. Snow density measurements were carried out for short periods, 1 or 2 h, during which the densification of the deposited snow was negligible. Also, we grouped snowfall events based on similar hydrometeor characteristics. As a result, we were able to obtain not only the qualitative relationships between the main types of snow and snowfall density as reported by previous researchers, but also quantitative relationships between snowfall density and the CMF density introduced here. CMF density is defined as the ratio between mass and volume, assuming the diameter of a sphere is equal to the CMF size component. This quantitative relationship provides a means for more precise estimation of snowfall density based on snow type (hydrometeor characteristics), by using hydrometeor size and fall speed data to derive initial densities for numerical snowpack models, and the snow-to-liquid ratio for winter weather forecasting. In fact, we found that this method can more accurately estimate snowfall density compared with using meteorological elements, which is the method generally used in current snowpack models, even though some issues remain in parameterization for practical use. Transferability of the method developed in the temperate climate zone, where riming and aggregation are predominant, to other snowy areas is also an issue. However, the methodology presented in this study would be useful for other kinds of snow.
Perception of wine labels by generation Z: eye-tracking experiment
Authors: Mokrý Stanislav , Birčiaková Nada , Slováčková Tereza , Stávková Jana , Nagyová Ľudmila 
Published: November 2016

Product quality is the result of an involved technological process. For the customer, product quality is not easy to grasp and the decision to buy the product is more influenced by the customer's perception of quality than by quality itself. It is therefore the result of many factors making an impression on the customer, their personal taste and the mood of the moment. The role of marketing is to understand the factors that have a customer impact. We need to identify the factors the customer is aware of and is able to communicate. Yet there are also a number of factors at play that affect the customer without their being aware of it. The aim of the paper is to get to know customer behaviour not just through the factors the customer communicates (answering questions) but to seek new methods that allow an objective examination of the customer's stimulus response, in our research case, using eye-tracking technology. The research study was conducted by way of an experiment with concurrent questioning in June 2016. There were 44 respondents taking part in the experiment, aged from 19 to 25 (Generation Z). The experiment set out to identify the importance of various visual attributes of a bottle of white wine, using a total of 7 stimuli. The experiment was carried out using the method called A/B testing, whereby one half of the respondents (A) was shown the original version of the stimulus and the second half (B) the modified stimulus. The eye-tracking research was carried out using remote eye-tracker SMI RED 250 at a sampling frequency of 125 Hz. In answering questions, the respondents evaluated the importance of the factors of price, type, awards, the shape and colour of the bottle and information on the label, i.e. information about the producer (maker) of the wine, wine variety, wine-growing region, country of origin, year of vintage and the sugar content indication. The paper concludes with a summary of the respective importance of the individual visual attributes that Generation Z consumers are most influenced by, when purchasing bottled white wine.

A Way Forward Beyond Karl Popper’s and Donald T. Campbell’s Dead-End Evolutionary Epistemologies
Authors: Wettersten John 
Published: November 2016

Abstract
Theories of natural thought processes have traditionally served as foundations for philosophies of science. The source of all knowledge is passively received observations; these are combined to produce certain knowledge. After David Hume showed that this was not possible, deductivist alternatives, that is, theories that find a source of knowledge in ideas not derived from observations, from Immanuel Kant to William Whewell in the mid-19th century, were introduced. In response, traditional associationist and inductivist views were refurbished; a deductivist alternative was developed by the Würzburg School. Much later Karl Popper in philosophy and Donald T. Campbell in psychology integrated this view with evolutionary theory. Campbell wanted thereby to find a justificationist view, which would reduce philosophy of science to cognitive psychology; Popper rejected both justificationism and the reduction of philosophy of science to psychology. Campbell thought all rational processes were innate psychological processes; Popper thought psychological processes were used to develop various rational processes. Campbell could not show that all rational thought was reducible to innate psychological processes, nor how some justification of scientific theories was possible. Popper could not show how evolutionary theory contributed to our knowledge of psychological thought processes. Both failed to observe that cognitive processes are social; people have learned how to think by learning how to interact in social groups seeking understanding. When innate thought processes are studied as social characteristics, evolutionary theory can contribute to both cognitive psychology and the theory of rationality, as both Popper and Campbell wanted it to do.
Von Willebrand factor processing
Authors: Brehm Maria 
Published: November 2016

SummaryVon Willebrand factor (VWF) is a multimeric glycoprotein essential for primary haemostasis that is produced only in endothelial cells and megakaryocytes. Key to VWF’s function in recruitment of platelets to the site of vascular injury is its multimeric structure. The individual steps of VWF multimer biosynthesis rely on distinct posttranslational modifications at specific pH conditions, which are realized by spatial separation of the involved processes to different cell organelles. Production of multimers starts with translocation and modification of the VWF prepropolypeptide in the endoplasmic reticulum to produce dimers primed for glycosylation. In the Golgi apparatus they are further processed to multimers that carry more than 300 complex glycan structures functionalized by sialylation, sulfation and blood group determinants. Of special importance is the sequential formation of disulfide bonds with different functions in structural support of VWF multimers, which are packaged, stored and further processed after secretion. Here, all these processes are being reviewed in detail including background information on the occurring biochemical reactions.
