In our study, consciousness for fair consumption (CFC) is defined as a latent disposition of consumers to prefer products that are produced and traded in compliance with fair labour and business practices. A scale to measure CFC was conceptualized and tested in three independent empirical studies. Two studies were conducted at European universities (2010 and 2012) and used 352 and 362 undergraduate business students respectively. The third study, conducted in 2011, used 141 employees at a European university. The results confirmed the reliability and validity of the new CFC scale across samples. While being moderately related to other aspects of sustainable consumption such as ecological concern and moral reasoning, CFC was significantly distinct from those concepts.

Il n'y avait que quelques philologues 'id{\´e}alistes' qui poursuivaient ce type de recherche. Ainsi, Karl Vossler constatait un parall{\´e}lisme entre la langue et la culture et les consid{\´e}rait comme r{\´e}sultats de la cr{\´e}ation humaine. Le m{\´e}contentement quant {\`a} la description des langues selon le paradigme positiviste des n{\´e}ogrammairiens s'articulait nettement. Le concept d'une vision linguistique du monde fut d{\´e}velopp{\´e} dans la th{\´e}orie des n{\´e}ohumboldtiens (Weisgerber, Trier et autres) qui affirmaient que l'individu s'approprie le monde {\`a} travers la langue. Des diff{\´e}rences entre des langues influeraient consid{\´e}rablement sur les facult{\´e}s cognitives des hommes et sur leur comportement. L'id{\´e}e humboldtienne de l'energeia se trouvait exclue de ces th{\´e}ories qui aspiraient {\`a} un renouvellement de la langue maternelle dans le sens d'une 'grammaire {\`a} partir du contenu' (inhaltbezogene Grammatik). Ce type de r{\´e}flexion linguistique se pr{\^e}tait aussi {\`a} une utilisation politique sous le national-socialisme. La th{\´e}orie de Weisgerber, d{\´e}clar{\´e}e comme antiraciste et anti-national-socialiste par l'auteur lui-m{\^e}me, fut consid{\´e}r{\´e}e comme « mother-tongue fascism » par Christopher Hutton. La relation entre le relativisme linguistique et la doctrine nationale-socialiste est {\´e}vidente dans les {\´e}crits de plusieurs auteurs, par exemple dans « notre langue maternelle comme arme et instrument de la pens{\´e}e allemande » de Georg Schmidt-Rohr. Il y eut des implications racistes de la th{\´e}orie de quelques indo-germanistes bien avant 1933.

HK620TSP binds hexasaccharide fragments with low affinity, but single amino acid exchanges generated a set of high-affinity mutants with submicromolar dissociation constants. Isothermal titration calorimetry showed that only small amounts of heat were released upon complex formation via a large number of direct and solvent-mediated hydrogen bonds between carbohydrate and protein. At room temperature, association was both enthalpy- and entropy-driven emphasizing major solvent rearrangements upon complex formation. Crystal structure analysis showed identical protein and sugar conformers in the TSP complexes regardless of their hexasaccharide affinity. Only in one case, a TSP mutant bound a different hexasaccharide conformer. The extended sugar binding site could be dissected in two regions: first, a hydrophobic pocket at the reducing end with minor affinity contributions. Access to this site could be blocked by a single aspartate to asparagine exchange without major loss in hexasaccharide affinity. Second, a region where the specific exchange of glutamate for glutamine created a site for an additional water molecule. Side-chain rearrangements upon sugar binding led to desolvation and additional hydrogen bonding which define this region of the binding site as the high-affinity scaffold.}, language = {en} } @article{BullerLaschewskyWischerhoff2013, author = {Buller, Jens and Laschewsky, Andr{\´e} and Wischerhoff, Erik}, title = {Photoreactive oligoethylene glycol polymers - versatile compounds for surface modification by thin hydrogel films}, series = {Soft matter}, volume = {9}, journal = {Soft matter}, number = {3}, publisher = {Royal Society of Chemistry}, address = {Cambridge}, issn = {1744-683X}, doi = {10.1039/c2sm26879e}, pages = {929 -- 937}, year = {2013}, abstract = {Solid surfaces are modified using photo-crosslinkable copolymers based on oligo(ethylene glycol) methacrylate (OEGMA) bearing 2-(4-benzoylphenoxy) ethyl methacrylate (BPEM) as a photosensitive crosslinking unit.

The influence of polymer concentration as well as of the start and target temperatures is addressed. In all cases, the micellar collapse is very fast. The collapsed micelles immediately form small clusters which contain voids. They densify which slows down or even stops their growth. For low concentrations and target temperatures just above the CP, i.e. shallow temperature jumps, the subsequent growth of the clusters is described by diffusion-limited aggregation. In contrast, for higher concentrations and/or higher target temperatures, i.e. deep temperature jumps, intermicellar bridges dominate the growth. Eventually, in all cases, the clusters coagulate which results in macroscopic phase separation. For shallow temperature jumps, the cluster surfaces stay rough; whereas for deep temperature jumps, a concentration gradient develops at late stages.

Although a high level of self-compatibility was demonstrated experimentally, the very low natural fruit set (1.4-1.9 \%) clearly indicated that the species depends on external agents for pollination. Our observations suggest that L. curtisii is pollinated by beetles, as Lema unicolor (Chrysomelidae) and Clinteria ducalis (Scarabaeidae) were the only flower visitors observed to carry pollinaria of this species. The hypothesis of specialised cantharophily is further supported by 2-methylbutyric acid and caproic acid being striking components of the floral scent. Judging from the lack of nectar and the behaviour of visiting beetles, the pollination system seems to rely on food or brood site deception. Retention of the anther on the pollinarium for some time after pollinarium removal probably reduces the frequency of insect-mediated autogamy and geitonogamy in Luisia curtisii-a possibility that was supported by comparative data on (1) the anther retention time and inflorescence visitation time of Lema unicolor and (2) stigma and anther length in the orchid. Existing reports of specialised beetle pollination in orchids are reviewed, and we conclude that there is accumulating evidence that specialised cantharophily is more common in the Orchidaceae than previously assumed.}, language = {en} } @article{HorikoshiYaghootkarMookKanamorietal.2013, author = {Horikoshi, Momoko and Yaghootkar, Hanieh and Mook-Kanamori, Dennis O. and Sovio, Ulla and Taal, H.

Moreover, there is still little knowledge on the spatial-temporal scales at which speciation occurs, that is, arrangement of habitat patches, abruptness of habitat transitions, climate and habitat changes interacting with selective forces. To investigate these questions, we quantified variation on a fine geographical scale analysing morphological (shell) and genetic data sets coupled with environmental data in the land snail Murella muralis, endemic to the Mediterranean island of Sicily. Analysis of a fragment of the mitochondrial DNA cytochrome oxidase I gene (COI) and eight nuclear microsatellite loci showed that genetic variation is highly structured at a very fine spatial scale by local palaeogeographical events and historical population dynamics. Molecular clock estimates, calibrated here specifically for Tyrrhenian land snails, provided a framework of palaeogeographical events responsible for the observed geographical variations and migration routes. Finally, we showed for the first time well-documented lines of evidence of selection in the past, which explains divergence of land snail shell shapes. We suggest that time and palaeogeographical history acted as constraints in the progress along the ecological speciation continuum. Our study shows that testing for correlation among palaeogeography, morphology and genetic data on a fine geographical scale provides information fundamental for a detailed understanding of ecological speciation processes.}, language = {en} } @article{HechavarriaMaciasVateretal.2013, author = {Hechavarria, Julio C. and Macias, Silvio and Vater, Marianne and Mora, Emanuel C. and K{\"o}ssl, Manfred}, title = {Evolution of neuronal mechanisms for echolocation specializations for target-range computation in bats of the genus Pteronotus}, series = {The journal of the Acoustical Society of America}, volume = {133}, journal = {The journal of the Acoustical Society of America}, number = {1}, publisher = {American Institute of Physics}, address = {Melville}, issn = {0001-4966}, doi = {10.1121/1.4768794}, pages = {570 -- 578}, year = {2013}, abstract = {Delay tuning was studied in the auditory cortex of Pteronotus quadridens.

P. quadridens and P. parnellii use comparable heteroharmonic target-range computation strategies even though they do not use biosonar calls of a similar design. P. quadridens uses short constant-frequency (CF)/frequency-modulated (FM) echolocation calls, while P. parnellii uses long CF/FM calls.

We found that the accumulation of arachidonic acid (ARA) in Daphnia increased from early summer to late summer and autumn. However, ARA requirements of Daphnia appeared to be constant throughout the year, because the accumulation of ARA increased when the dietary ARA supply decreased. In the size fraction 140 m, we found an increased accumulation of docosahexaenoic acid (DHA) during late summer and autumn. These seasonal changes in DHA accumulation were linked to changes in the proportion of copepods in this size fraction, which may have increasingly accumulated DHA for active overwintering.

Such a pattern of chance performance is a typical trait of Broca's aphasia, but can be found in other aphasic syndromes as well. Many researchers have argued that chance behaviour is the result of a guessing strategy, which is adopted in the face of a syntactic breakdown in sentence processing. Aims: Capitalising on new evidence from recent studies investigating online sentence comprehension in aphasia using the visual world paradigm, the aim of this paper is to review the concept of chance performance as a reflection of a syntactic impairment in sentence processing and to re-examine the conventional interpretation of chance performance as a guessing behaviour. Main Contribution: Based on a review of recent evidence from visual world paradigm studies, we argue that the assumption of chance performance equalling guessing is not necessarily compatible with actual real-time parsing procedures in people with aphasia. We propose a reinterpretation of the concept of chance performance by assuming that there are two distinct processing mechanisms underlying sentence comprehension in aphasia. Correct responses are always the result of normal-like parsing mechanisms, even in those cases where the overall performance pattern is at chance. Incorrect responses, on the other hand, are the result of intermittent deficiencies of the parser. Hence the random guessing behaviour that persons with aphasia often display does not necessarily reflect a syntactic breakdown in sentence comprehension and a random selection between alternatives. Instead it should be regarded as a result of temporal deficient parsing procedures in otherwise normal-like comprehension routines. Conclusion: Our conclusion is that the consideration of behavioural offline data alone may not be sufficient to interpret a performance in language tests and subsequently draw theoretical conclusions about language impairments. Rather it is important to call on additional data from online studies that look at language processing in real time in order to gain a comprehensive picture about syntactic comprehension abilities of people with aphasia and possible underlying deficits.}, language = {en} } @article{MuehlbauerBesemerWehrleetal.2013, author = {M{\"u}hlbauer, Thomas and Besemer, Carmen and Wehrle, Anja and Gollhofer, Albert and Granacher, Urs}, title = {Relationship between strength; balance and mobility in children aged 7-10 years}, series = {Gait \& posture}, volume = {37}, journal = {Gait \& posture}, number = {1}, publisher = {Elsevier}, address = {Clare}, issn = {0966-6362}, doi = {10.1016/j.gaitpost.2012.06.022}, pages = {108 -- 112}, year = {2013}, abstract = {The purpose of this study was to investigate the association between variables of lower extremity muscle strength, balance, and mobility assessed under various task conditions.

Prevalence estimates of PSS were highly variable, ranging from 4\% to 42.6\%, with the prevalence of disabling spasticity ranging from 2\% to 13\%. Data on phases of the PSS continuum revealed evidence of PSS in 4\% to 27\% of those in the early time course (1-4 weeks poststroke), 19\% to 26.7\% of those in the postacute phase (1-3 months poststroke), and 17\% to 42.6\% of those in the chronic phase (>3 months poststroke). Data also identified key risk factors associated with the development of spasticity, including lower Barthel Index scores, severe degree of paresis, stroke-related pain, and sensory deficits. Although such indices could be regarded as predictors of PSS and thus enable early identification and treatment, the different measures of PSS used in those studies limit the strength of the findings. To optimize evaluation in the different phases of care, the best possible assessment of PSS would make use of a combination of indicators for clinical impairment, motor performance, activity level, quality of life, and patient-reported outcome measures.

The youngest participants were prone to accept ungrammatical sentences by assigning a resultative meaning.

In contrast, the adults rejected or amended those sentences. The conclusion is (a) that the children seemed to rely on the sentence structure as a primary cue to compute the meaning of an utterance and (b) that, in contrast with adults, the youngest children in particular had not yet learned the relevant semantic properties of verbs that determine the selectional restrictions and thus the syntactic options of verbs.

The concept will be used to account for the meaning spectrum of the present-day English progressive, which, it will be argued, no monosemic approach to date can account for. Taking a look at the diachrony of the construction will help to reveal that the various "exceptions" found in the use of the progressive can be understood as reflections of different stages in its development. Older, less grammaticalized or less well-defined usage patterns thus often survive in certain restricted niches next to the newer, more grammaticalized or more clear-cut functions, representing different diachronic layers. In addition to this diachronic motivation for synchronic meaning variety, the article will also address the crucial question of how a present-day hearer of a progressive form is able to decode the specific meaning intended by the speaker based on contextual clues. The article ends with some suggestions for further applications of the concept of functional layering.}, language = {en} } @article{HammerOhrnbergerFaeh2013, author = {Hammer, Conny and Ohrnberger, Matthias and Faeh, Donat}, title = {Classifying seismic waveforms from scratch: a case study in the alpine environment}, series = {Geophysical journal international}, volume = {192}, journal = {Geophysical journal international}, number = {1}, publisher = {Oxford Univ.

The basic step for successfully analyzing those data is the correct detection of various event types. However, the visually scanning process is a time-consuming task. Applying standard techniques for detection like the STA/LTAtrigger still requires the manual control for classification. Here, we present a useful alternative. The incoming data stream is scanned automatically for events of interest. A stochastic classifier, called hidden Markov model, is learned for each class of interest enabling the recognition of highly variable waveforms. In contrast to other automatic techniques as neural networks or support vector machines the algorithm allows to start the classification from scratch as soon as interesting events are identified. Neither the tedious process of collecting training samples nor a time-consuming configuration of the classifier is required. An approach originally introduced for the volcanic task force action allows to learn classifier properties from a single waveform example and some hours of background recording. Besides a reduction of required workload this also enables to detect very rare events. Especially the latter feature provides a milestone point for the use of seismic devices in alpine warning systems. Furthermore, the system offers the opportunity to flag new signal classes that have not been defined before. We demonstrate the application of the classification system using a data set from the Swiss Seismological Survey achieving very high recognition rates. In detail we document all refinements of the classifier providing a step-by-step guide for the fast set up of a well-working classification system.}, language = {en} } @article{HobigerCornouWatheletetal.2013, author = {Hobiger, M. and Cornou, C. and Wathelet, M. and Di Giulio, G. and Knapmeyer-Endrun, B. and Renalier, F. and Bard, Pierre-Yves and Savvaidis, Alexandros and Hailemikael, S. and Le Bihan, N. and Ohrnberger, Matthias and Theodoulidis, N.}, title = {Ground structure imaging by inversions of Rayleigh wave ellipticity sensitivity analysis and application to European strong-motion sites}, series = {Geophysical journal international}, volume = {192}, journal = {Geophysical journal international}, number = {1}, publisher = {Oxford Univ.

A widespread, but time-consuming technique to retrieve the parameters of the local underground is the drilling of boreholes. Another way to obtain the shear wave velocity profile at a given location is the inversion of surface wave dispersion curves. To ensure a good resolution for both superficial and deeper layers, the used dispersion curves need to cover a wide frequency range. This wide frequency range can be obtained using several arrays of seismic sensors or a single array comprising a large number of sensors. Consequently, these measurements are time-consuming. A simpler alternative is provided by the use of the ellipticity of Rayleigh waves. The frequency dependence of the ellipticity is tightly linked to the shear wave velocity profile. Furthermore, it can be measured using a single seismic sensor. As soil structures obtained by scaling of a given model exhibit the same ellipticity curve, any inversion of the ellipticity curve alone will be ambiguous. Therefore, additional measurements which fix the absolute value of the shear wave velocity profile at some points have to be included in the inversion process. Small-scale spatial autocorrelation measurements or MASW measurements can provide the needed data. Using a theoretical soil structure, we show which parts of the ellipticity curve have to be included in the inversion process to get a reliable result and which parts can be omitted. Furthermore, the use of autocorrelation or high-frequency dispersion curves will be highlighted. The resulting guidelines for inversions including ellipticity data are then applied to real data measurements collected at 14 different sites during the European NERIES project. It is found that the results are in good agreement with dispersion curve measurements. Furthermore, the method can help in identifying the mode of Rayleigh waves in dispersion curve measurements.}, language = {en} } @article{SachseWuestenhagenSamalikovaetal.2013, author = {Sachse, Rita and W{\"u}stenhagen, Doreen Anja and Samalikova, Maria and Gerrits, Michael and Bier, Frank Fabian and Kubick, Stefan}, title = {Synthesis of membrane proteins in eukaryotic cell-free systems}, series = {Engineering in life sciences : Industry, Environment, Plant, Food}, volume = {13}, journal = {Engineering in life sciences : Industry, Environment, Plant, Food}, number = {1}, publisher = {Wiley-Blackwell}, address = {Hoboken}, issn = {1618-0240}, doi = {10.1002/elsc.201100235}, pages = {39 -- 48}, year = {2013}, abstract = {Cell-free protein synthesis (CFPS) is a valuable method for the fast expression of difficult-to-express proteins as well as posttranslationally modified proteins.
