Todo crimen es un acto de posesión: Buñuel y sus heroínas

Liane Ströbel
pp. 53-67. Ensayo de un crimen is a film in which nothing is what it seems. Buñuel seduces us with his mysterious and disconcerting universe, and with his intimate look into the lives of his protagonists, who lose themselves in a surreal labyrinth of truncated plans. The following analysis will illustrate through structure and narrative the main constellations formed by the protagonist and the motley female characters and will clarify the relationship between victims and...

If not now, then when – making the energy transition happen

Schmidt, Indra Spiecker genannt Döhmann, Frithjof Staiß, Annika Seiler, Cyril Stephanos & Eberhard Umbach
The next four years are critical – time is running out, but we still have one last chance. If the new German government is too slow to make the key decisions, it will be almost impossible to meet Germany’s climate targets for 2030 and 2045. But if it recognises that the new parliament offers an opportunity for a fundamental, groundbreaking change of course, it can bring urgently needed momentum to climate and energy policy and...

El difícil camino hacia la Independencia: los desafíos de la emancipación política y del compromiso periodístico en México

Frank Leinen
pp. 23-69 On the occasion of the bicentenary of the Mexican Declaration of Independence in 1821, this article aims to examine the extent to which political and social processes, the gradual emergence of a public space and the increasingly dynamic development of the press interacted in the run-up to this event. The study reveals that in the course of the formation of a public opinion in the sense of Habermas, many periodicals saw themselves as...

Data from: Budget constraints affect male rats’ choices between differently priced commodities

Marijn Van Wingerden, Christine Marx & Tobias Kalenscher
Demand theory can be applied to analyse how a human or animal consumer changes her selection of commodities within a certain budget in response to changes in price of those commodities. This change in consumption assessed over a range of prices is defined as demand elasticity. Previously, income-compensated and income-uncompensated price changes have been investigated using human and animal consumers, as demand theory predicts different elasticities for both conditions. However, in these studies, demand elasticity...

Vicarious reward unblocks associative learning about novel cues in male rats

Sander Van Gurp, Jochen Hoog, Tobias Kalenscher & Marijn Van Wingerden
Many species, including humans, are sensitive to social signals and their valuation is important in social learning. When social cues indicate that a conspecific is experiencing reward, they could convey vicarious reward value and prompt social learning. Here, we introduce a task that investigates if mutual reward delivery in male rats can drive social reinforcement learning in a formal associative learning experiment. Using the blocking/unblocking paradigm, we found that when actor rats have fully learned...

Phylogenomic testing of root hypotheses - demonstrative datasets - Opisthokonta and Proteobacteria

Fernando Tria, Tal Dagan & Giddy Landan
The determination of the last common ancestor (LCA) of a group of species plays a vital role in evolutionary theory. Traditionally, an LCA is inferred by the rooting of a fully resolved species tree. From a theoretical perspective, however, inference of the LCA amounts to the reconstruction of just one branch - the root branch - of the true species tree, and should therefore be a much easier task than the full resolution of the...

Plastics Packaging in a Closed Loop – Potentials, Conditions, Challenges

Schlarb, Michael Schmidt … & Susanne Kadner
Most current patterns of production and consumption follow a linear “extract, produce, consume, dispose” model. According to the Circular Gap Report 2020, the global economy is just 9% circular. This economic model is contributing to a massive transgression of “planetary boundaries” and the destabilisation of ecosystems and factors essential to human life such as the climate system and biodiversity. As a result, there is currently much discussion of a paradigm shift in the industrial value...

Strommarktdesign 2030: Die Förderung der erneuerbaren Energien wirksam und effizient gestalten

Justus Haucap, Jürgen Kühling, Munib Amin, Gert Brunekreeft, Dörte Fouquet, Veronika Grimm, Jörg Gundel, Martin Kment, Wolfgang Ketter, Jochen Kreusel, Charlotte Kreuter-Kirchhof, Mario Liebensteiner, Albert Moser, Marion Ott, Christian Rehtanz, Heike Wetzel, Jonathan Meinhof, Marlene Wagner, Miriam Borgmann & Cyril Stephanos
Bis 2030 soll der Anteil erneuerbarer Energien im Stromsystem 80% betragen. Nicht nur für den Klimaschutz, auch für die Unabhängigkeit von fossilen Brennstoffen und einzelnen Exportländern ist der Ausbau der erneuerbaren Energien zentral. Diesen möchte die Bundesregierung mit der Überarbeitung des Erneuerbare-Energien-Gesetzes forcieren und auch das Strommarktdesign an die Erfordernisse der Zeit anpassen. Doch mit diesem Ausbau sind auch enorme Kosten verbunden. Im Impulspapier „Strommarktdesign 2030: Die Förderung der erneuerbaren Energien wirksam und effizient gestalten“...

Data from: Rate maximization and hyperbolic discounting in human experiential intertemporal decision making

Maayke Suzanne Seinstra, Manuela Sellitto & Tobias Kalenscher
Decisions between differently timed outcomes are a well-studied topic in as diverse academic disciplines as economics, psychology, and behavioral ecology. Humans and other animals have been shown to make these intertemporal choices by hyperbolically devaluing rewards as a function of their delays (‘delay discounting’), thus often deemed to behave myopically. In behavioral ecology, however, intertemporal choices are assumed to meet optimization principles, that is, the maximization of energy or reward rate. Thus far it is...

Data from: The role of photorespiration during the evolution of C4 photosynthesis in the genus Flaveria

Julia Mallmann, David Heckmann, Andrea Bräutigam, Martin J. Lercher, Andreas P. M. Weber, Peter Westhoff & Udo Gowik
C4 photosynthesis represents a most remarkable case of convergent evolution of a complex trait, which includes the reprogramming of the expression patterns of thousands of genes. Anatomical, physiological, and phylogenetic and analyses as well as computational modeling indicate that the establishment of a photorespiratory carbon pump (termed C2 photosynthesis) is a prerequisite for the evolution of C4. However, a mechanistic model explaining the tight connection between the evolution of C4 and C2 photosynthesis is currently...

CLSM data of CLE40, CLV3, WUS, BAM1, and CLV1 reporter lines in Arabidopsis thaliana

Jenia Schlegel, Gregoire Denay, Yvonne Stahl, Julia Schmid, Patrick Blümke, Rene H.Wink, Karine G. Pinto & Rüdiger Simon
Stem cell homeostasis in plant shoot meristems requires tight coordiantion between stem cell proliferation and cell differentiation. In Arabidopsis, stem cells express the secreted dodecapeptide CLAVATA3 (CLV3), which signals through the leucine-rich repeat (LRR)–receptor kinase CLAVATA1 (CLV1) and related CLV1-family members to downregulate expression of the homeodomain transcription factor WUSCHEL (WUS). WUS protein moves from cells below the stem cell domain to the meristem tip and promotes stem cell identity, together with CLV3 expression, generating...

El periodismo en Puebla durante el período de la Independencia. Un análisis de las perspectivas de la construcción nacional y de la identidad mexicana en La Abeja Poblana, El Farol y El Amigo del Pueblo

Frank Leinen
pp. 41-101 Based on the thesis that the analysis of Mexican periodicals of the 19th century is excellently suited to a reconstruction of historical developments not only on a national, but also on regional and local levels, this article examines three newspapers of different political colours that were published in Puebla between 1820 and 1822, at the time of Mexico’s political disengagement from Spain: La Abeja Poblana, El Farol and El Amigo del Pueblo. Even...

Data from: Task-related effective connectivity reveals that the cortical rich club gates cortex-wide communication

Mario Senden, Niels Reuter, Martijn P. Van Den Heuvel, Rainer Goebel, Gustavo Deco & Matthieu Gilson
Higher cognition may require the globally coordinated integration of specialized brain regions into functional networks. A collection of structural cortical hubs—referred to as the rich club—has been hypothesized to support task-specific functional integration. In the present paper, we use a whole-cortex model to estimate directed interactions between 68 cortical regions from functional magnetic resonance imaging activity for four different tasks (reflecting different cognitive domains) and resting state. We analyze the state-dependent input and output effective...

Del mundo a los mundos: repensar la globalizacion desde la literatura mexicana

Vittoria Borsò
pp. 18-50 How to think the world, its plurality, coexistence in times of post-politics and after the global failure of theories of salvation? This article reviews theories of world, globe, sphere, worlding, planet, reflects on the most recent critiques of the concept of world and asks about the role of Mexican literature in the attempt to configure relational practices that allow thinking the plurality of worlds as the potential of a common world. The exploration...

In the shadows of snow leopards and the Himalayas: density and habitat selection of blue sheep in Manang, Nepal

Marc Filla, Rinzin Phunjok Lama, Tashi Rapte Ghale, Johannes Signer, Tim Filla, Raja Ram Aryal, Marco Heurich, Matthias Waltert, Niko Balkenhol & Igor Khorozyan
There is a growing agreement that conservation needs to be proactive and pay increased attention to common species and to the threats they face. The blue sheep (Pseudois nayaur) plays a key ecological role in sensitive high-altitude ecosystems of Central Asia and is among the main prey species for the globally vulnerable snow leopard (Panthera uncia). As the blue sheep has been increasingly exposed to human pressures, it is vital to estimate its population dynamics,...

Data from: Floral colours in a world without birds and bees: the plants of Macquarie Island

Mani Shrestha, Klaus Lunau, Alan Dorin, Brian Schulze, Mascha Bischoff, Martin Burd & Adrian G. Dyer
We studied biotically pollinated angiosperms on Macquarie Island, a remote site in the Southern Ocean with a predominately or exclusively dipteran pollinator fauna, in an effort to understand how flower colour affects community assembly. We compared a distinctive group of cream-green Macquarie Island flowers to the flora of likely source pools of immigrants and to a continental flora from a high latitude in the northern hemisphere. We used both dipteran and hymenopteran colour models and...

Data from: The genomes of two key bumblebee species with primitive eusocial organisation

Ben M. Sadd, Seth M. Barribeau, Guy Bloch, Dirk C. De Graaf, Peter Dearden, Christine Elsik, Jurgen Gadau, Cornelius Grimmelikhuijzen, Martin Hasselmann, Jeffrey Lozier, Hugh Robertson, Guy Smagghe, Eckart Stolle, Matthias Van Vaerenbergh, Robert Waterhouse, Erich Bornberg-Bauer, Steffan Klasberg, Anna Bennett, Francisco Camara, Roderic Guigo, Katharina Hoff, Marco Mariotti, Monica Munos-Torres, Terence Murphy, Didac Santesmasses … & Kim C. Worley
Background: The shift from solitary to social behavior is one of the major evolutionary transitions. Primitively eusocial bumblebees are uniquely placed to illuminate the evolution of highly eusocial insect societies. Bumblebees are also invaluable natural and agricultural pollinators, and there is widespread concern over recent population declines in some species. High-quality genomic data will inform key aspects of bumblebee biology, including susceptibility to implicated population viability threats. Results: We report the high quality draft genome...
