This article takes up the questions of what determines whether a treaty provision is successfully changed and why provisions are renegotiated at subsequent Intergovernmental Conferences. The article presents an institutionalist theory explaining success and renegotiation and tests the theory using all core institutional provisions by means of Qualitative Comparative Analysis. The causal analysis shows that low conflict potential of an issue is sufficient for successfully changing the treaties. Furthermore, high conflict potential of an issue and its fundamental change are sufficient for it to be renegotiated.}, language = {en} } @book{OPUS4-57966, title = {Entre los mundos}, editor = {Ferrer-Maestro, Juan Jos{\´e} and Kunst, Christiane and de la Fuente, David Hern{\´a}ndez and Faber, Eike}, publisher = {Presses universitaires de Franche-Comt{\´e}}, address = {Besan{\c{c}}on}, isbn = {978-2848675787}, pages = {802}, year = {2017}, language = {es} } @article{BetaKruse2017, author = {Beta, Carsten and Kruse, Karsten}, title = {Intracellular oscillations and waves}, series = {Annual review of condensed matter physics}, volume = {8}, journal = {Annual review of condensed matter physics}, publisher = {Annual Reviews}, address = {Palo Alto}, isbn = {978-0-8243-5008-6}, issn = {1947-5454}, doi = {10.1146/annurev-conmatphys-031016-025210}, pages = {239 -- 264}, year = {2017}, abstract = {Dynamic processes in living cells are highly organized in space and time. Unraveling the underlying molecular mechanisms of spatiotemporal pattern formation remains one of the outstanding challenges at the interface between physics and biology. A fundamental recurrent pattern found in many different cell types is that of self-sustained oscillations. They are involved in a wide range of cellular functions, including second messenger signaling, gene expression, and cytoskeletal dynamics. Here, we review recent developments in the field of cellular oscillations and focus on cases where concepts from physics have been instrumental for understanding the underlying mechanisms. We consider biochemical and genetic oscillators as well as oscillations that arise from chemo-mechanical coupling. Finally, we highlight recent studies of intracellular waves that have increasingly moved into the focus of this research field.}, language = {en} } @article{EndesfelderWeicheltStraussetal.2017, author = {Endesfelder, Stefanie and Weichelt, Ulrike and Strauß, Evelyn and Schl{\"o}r, Anja and Sifringer, Marco and Scheuer, Till and B{\"u}hrer, Christoph and Schmitz, Thomas}, title = {Neuroprotection by caffeine in hyperoxia-induced neonatal brain injury}, series = {International journal of molecular sciences}, volume = {18}, journal = {International journal of molecular sciences}, publisher = {Molecular Diversity Preservation International}, address = {Basel}, issn = {1422-0067}, doi = {10.3390/ijms18010187}, pages = {24}, year = {2017}, abstract = {Sequelae of prematurity triggered by oxidative stress and free radical-mediated tissue damage have coined the term "oxygen radical disease of prematurity". Caffeine, a potent free radical scavenger and adenosine receptor antagonist, reduces rates of brain damage in preterm infants. In the present study, we investigated the effects of caffeine on oxidative stress markers, anti-oxidative response, inflammation, redox-sensitive transcription factors, apoptosis, and extracellular matrix following the induction of hyperoxia in neonatal rats. The brain of a rat pups at postnatal Day 6 (P6) corresponds to that of a human fetal brain at 28-32 weeks gestation and the neonatal rat is an ideal model in which to investigate effects of oxidative stress and neuroprotection of caffeine on the developing brain. Six-day-old Wistar rats were pre-treated with caffeine and exposed to 80\% oxygen for 24 and 48 h. Caffeine reduced oxidative stress marker (heme oxygenase-1, lipid peroxidation, hydrogen peroxide, and glutamate-cysteine ligase catalytic subunit (GCLC)), promoted anti-oxidative response (superoxide dismutase, peroxiredoxin 1, and sulfiredoxin 1), down-regulated pro-inflammatory cytokines, modulated redox-sensitive transcription factor expression (Nrf2/Keap1, and NFκB), reduced pro-apoptotic effectors (poly (ADP-ribose) polymerase-1 (PARP-1), apoptosis inducing factor (AIF), and caspase-3), and diminished extracellular matrix degeneration (matrix metalloproteinases (MMP) 2, and inhibitor of metalloproteinase (TIMP) 1/2). Our study affirms that caffeine is a pleiotropic neuroprotective drug in the developing brain due to its anti-oxidant, anti-inflammatory, and anti-apoptotic properties.}, language = {en} } @article{ParkLuehrKervalishvilietal.2017, author = {Park, Jaeheung and L{\"u}hr, Hermann and Kervalishvili, Guram and Rauberg, Jan and Stolle, Claudia and Kwak, Young-Sil and Lee, Woo Kyoung}, title = {Morphology of high-latitude plasma density perturbations as deduced from the total electron content measurements onboard the Swarm constellation}, series = {Journal of geophysical research : A, Space physics}, volume = {122}, journal = {Journal of geophysical research : A, Space physics}, number = {1}, publisher = {American Geophysical Union}, address = {Washington}, issn = {2169-9380}, doi = {10.1002/2016JA023086}, pages = {1338 -- 1359}, year = {2017}, abstract = {In this study, we investigate the climatology of high-latitude total electron content (TEC) variations as observed by the dual-frequency Global Navigation Satellite Systems (GNSS) receivers onboard the Swarm satellite constellation. The distribution of TEC perturbations as a function of geographic/magnetic coordinates and seasons reasonably agrees with that of the Challenging Minisatellite Payload observations published earlier. Categorizing the high-latitude TEC perturbations according to line-of-sight directions between Swarm and GNSS satellites, we can deduce their morphology with respect to the geomagnetic field lines. In the Northern Hemisphere, the perturbation shapes are mostly aligned with the L shell surface, and this anisotropy is strongest in the nightside auroral (substorm) and subauroral regions and weakest in the central polar cap. The results are consistent with the well-known two-cell plasma convection pattern of the high-latitude ionosphere, which is approximately aligned with L shells at auroral regions and crossing different L shells for a significant part of the polar cap. In the Southern Hemisphere, the perturbation structures exhibit noticeable misalignment to the local L shells. Here the direction toward the Sun has an additional influence on the plasma structure, which we attribute to photoionization effects. The larger offset between geographic and geomagnetic poles in the south than in the north is responsible for the hemispheric difference.}, language = {en} } @article{ChujfiLaRocheMeinel2017, author = {Chujfi-La-Roche, Salim and Meinel, Christoph}, title = {Matching cognitively sympathetic individual styles to develop collective intelligence in digital communities}, series = {AI \& society : the journal of human-centred systems and machine intelligence}, volume = {35}, journal = {AI \& society : the journal of human-centred systems and machine intelligence}, number = {1}, publisher = {Springer}, address = {New York}, issn = {0951-5666}, doi = {10.1007/s00146-017-0780-x}, pages = {5 -- 15}, year = {2017}, abstract = {Creation, collection and retention of knowledge in digital communities is an activity that currently requires being explicitly targeted as a secure method of keeping intellectual capital growing in the digital era. In particular, we consider it relevant to analyze and evaluate the empathetic cognitive personalities and behaviors that individuals now have with the change from face-to-face communication (F2F) to computer-mediated communication (CMC) online. This document proposes a cyber-humanistic approach to enhance the traditional SECI knowledge management model. A cognitive perception is added to its cyclical process following design thinking interaction, exemplary for improvement of the method in which knowledge is continuously created, converted and shared. In building a cognitive-centered model, we specifically focus on the effective identification and response to cognitive stimulation of individuals, as they are the intellectual generators and multiplicators of knowledge in the online environment. Our target is to identify how geographically distributed-digital-organizations should align the individual's cognitive abilities to promote iteration and improve interaction as a reliable stimulant of collective intelligence. The new model focuses on analyzing the four different stages of knowledge processing, where individuals with sympathetic cognitive personalities can significantly boost knowledge creation in a virtual social system. For organizations, this means that multidisciplinary individuals can maximize their extensive potential, by externalizing their knowledge in the correct stage of the knowledge creation process, and by collaborating with their appropriate sympathetically cognitive remote peers.}, language = {en} } @article{RomingerFinkWeissetal.2017, author = {Rominger, Christian and Fink, Andreas and Weiss, Elisabeth M. and Bosch, Jannis and Papousek, Ilona}, title = {Allusive thinking (remote associations) and auditory top-down inhibition skills differentially predict creativity and positive schizotypy}, series = {Cognitive neuropsychiatry}, volume = {22}, journal = {Cognitive neuropsychiatry}, number = {2}, publisher = {Taylor \& Francis}, address = {Abingdon}, issn = {1354-6805}, doi = {10.1080/13546805.2016.1278361}, pages = {108 -- 121}, year = {2017}, abstract = {Introduction: Positive schizotypy and creativity seem to be linked. However, the question still remains why they are related, and what may make the difference? As creative ideation is hypothesised as a dual process (association and inhibition), the propensity for remote associations might be a shared mechanism. However, positive schizotypy and creative thinking might be differentially linked to inhibition. Therefore, this study investigated a potentially overlapping feature of positive schizotypy and creativity (remote associations) as well as a potential dissociative factor (auditory inhibition). Methods: From a large screening sample, 46 participants covering a broad range of positive schizotypy were selected. Association proneness was assessed via two association tasks, auditory inhibition skill with the forced-left condition of the Dichotic Listening Test, and creative thinking by means of two creative ideation tests. Results: Positive schizotypy and creative thinking were positively associated. Both traits were linked to lower rates of common associations. However, creative thinking was associated with higher and positive schizotypy with lower inhibitory control in the auditory domain. Conclusions: While creativity and positive schizotypy shared some variance (related to remote associations), profound inhibition skills may be vital for creative performance and may coincide with lower levels of positive schizotypy.}, language = {en} } @article{UsanovaShprits2017, author = {Usanova, Maria E. and Shprits, Yuri Y.}, title = {Inner magnetosphere coupling}, series = {Journal of geophysical research : Space physics}, volume = {122}, journal = {Journal of geophysical research : Space physics}, number = {1}, publisher = {American Geophysical Union}, address = {Washington}, issn = {2169-9380}, doi = {10.1002/2016JA023614}, pages = {102 -- 104}, year = {2017}, abstract = {The dynamics of the inner magnetosphere is strongly governed by the interactions between different plasma populations that are coupled through large-scale electric and magnetic fields, currents, and wave-particle interactions. Inner magnetospheric plasma undergoes self-consistent interactions with global electric and magnetic fields. Waves excited in the inner magnetosphere from unstable particle distributions can provide energy exchange between different particle populations in the inner magnetosphere and affect the ring current and radiation belt dynamics. The ionosphere serves as an energy sink and feeds the magnetosphere back through the cold plasma outflow. The precipitating inner magnetospheric particles influence the ionosphere and upper atmospheric chemistry and affect climate. Satellite measurements and theoretical studies have advanced our understanding of the dynamics of various plasma populations in the inner magnetosphere. However, our knowledge of the coupling processes among the plasmasphere, ring current, radiation belts, global magnetic and electric fields, and plasma waves generated within these systems is still incomplete. This special issue incorporates extended papers presented at the Inner Magnetosphere Coupling III conference held 23-27 March 2015 in Los Angeles, California, USA, and includes modeling and observational contributions addressing interactions within different plasma populations in the inner magnetosphere (plasmasphere, ring current, and radiation belts), coupling between fields and plasma populations, as well as effects of the inner magnetosphere on the ionosphere and atmosphere.}, language = {en} } @article{ReifegersteMeyerZwitserlood2017, author = {Reifegerste, Jana and Meyer, Antje and Zwitserlood, Pienie}, title = {Inflectional complexity and experience affect plural processing in younger and older readers of Dutch and German}, series = {Language, cognition and neuroscience}, volume = {32}, journal = {Language, cognition and neuroscience}, number = {4}, publisher = {Routledge, Taylor \& Francis Group}, address = {Abingdon}, issn = {2327-3798}, doi = {10.1080/23273798.2016.1247213}, pages = {471 -- 487}, year = {2017}, abstract = {According to dual-route models of morphological processing, regular inflections can be retrieved as whole-word forms or decomposed into morphemes.

For all Dutch participants and older German participants, we replicated the interaction between number and dominance reported by Baayen and colleagues. Younger German participants showed a main effect of number, indicating decomposition of all plurals. Access to stored forms seems to depend on morphological richness and experience with word forms.
