We predicted only locality effects, that is, a slowdown produced by increased dependency distance (Gibson, 2000; Lewis and Vasishth, 2005). Furthermore, we expected stronger locality effects for readers with low working memory capacity. Contrary to our predictions, low-capacity readers showed faster reading with increased distance, while high-capacity readers showed locality effects. We suggest that while the locality effects are compatible with memory-based explanations, the speedup of low-capacity readers can be explained by an increased probability of retrieval failure. We present a computational model based on ACT-R built under the previous assumptions, which is able to give a qualitative account for the present data and can be tested in future research. Our results suggest that in some cases, interpreting longer RTs as indexing increased processing difficulty and shorter RTs as facilitation may be too simplistic: The same increase in processing difficulty may lead to slowdowns in high-capacity readers and speedups in low-capacity ones. Ignoring individual level capacity differences when investigating locality effects may lead to misleading conclusions.

Yet little is known about what determines whether a specific idea for constructive change brought up by an employee will be approved or rejected by a supervisor. Drawing on interactionist theories of motivation and personality, we propose that a supervisor will be least likely to support an idea when it threatens the supervisor’s power motive, and when it is perceived to serve the employee’s own striving for power. The prosocial versus egoistic intentions attributed to the idea presenter are proposed to mediate the latter effect. We conducted three scenario-based studies in which supervisors evaluated fictitious ideas voiced by employees that – if implemented – would have power-related consequences for them as a supervisor. Results show that the higher a supervisors’ explicit power motive was, the less likely they were to support a power-threatening idea (Study 1, N = 60). Moreover, idea support was less likely when this idea was proposed by an employee that was described as high (rather than low) on power motivation (Study 2, N = 79); attributed prosocial intentions mediated this effect. Study 3 (N = 260) replicates these results.

Deferred Choice on Blockchain Using Oracles T2 - Zweitveröffentlichungen der Universität Potsdam : Reihe der Digital Engineering Fakultät N2 - First come, first served: Critical choices between alternative actions are often made based on events external to an organization, and reacting promptly to their occurrence can be a major advantage over the competition. In Business Process Management (BPM), such deferred choices can be expressed in process models, and they are an important aspect of process engines. Blockchain-based process execution approaches are no exception to this, but are severely limited by the inherent properties of the platform: The isolated environment prevents direct access to external entities and data, and the non-continual runtime based entirely on atomic transactions impedes the monitoring and detection of events. In this paper we provide an in-depth examination of the semantics of deferred choice, and transfer them to environments such as the blockchain. We introduce and compare several oracle architectures able to satisfy certain requirements, and show that they can be implemented using state-of-the-art blockchain technology.

Three kinds of CNDs are prepared using different sets of above mentioned starting materials. The as-synthesized CNDs: C-CND (starch only), N-CND 1 (starch in TAE) and N-CND 2 (TAE only) exhibit highly homogenous PL and are ready to use without need for further purification. The CNDs are stable over a long period of time (>1 year) either in solution or as freeze-dried powder. Depending on starting material, CNDs with PL quantum yield (PLQY) ranging from less than 1% up to 28% are obtained. The influence of the precursor concentration, reaction time and type of additives on the optical properties (UV-Vis absorption, PL emission spectrum and PLQY) is carefully investigated, providing insight into the chemical processes that occur during CND formation. Remarkably, upon freeze-drying the initially brown CND-solution turns into a non-fluorescent white/slightly brown powder which recovers PL in aqueous solution and can potentially be applied as fluorescent marker in bio-imaging, as a reduction agent or as a photocatalyst.

Organic based fluorescence processes of the MOF backbone as well as metal based luminescence of the dopants are combined to one homogenous single source emitter while retaining the MOF's porosity. The lanthanide ions Eu3+ and Tb3+ were doped in situ into IFP-1 upon formation of the MOF by intercalation into the micropores of the growing framework without a structure directing effect. Furthermore, the color point is temperature sensitive, so that a cold white light with a higher blue content is observed at 77 K and a warmer white light at room temperature (RT) due to the reduction of the organic emission at higher temperatures. The study further illustrates the dependence of the amount of luminescent ions on porosity and sorption properties of the MOF and proves the intercalation of luminescence centers into the pore system by low-temperature site selective photoluminescence spectroscopy, SEM and EDX. It also covers an investigation of the border of homogenous uptake within the MOF pores and the formation of secondary phases of lanthanide formates on the surface of the MOF. Crossing the border from a homogenous co-doping to a two-phase composite system can be beneficially used to adjust the character and warmth of the white light. This study also describes two-color emitters of the formula Ln@IFP-1a–d (Ln: Eu, Tb) by doping with just one lanthanide Eu3+ or Tb3+.

Evidence From a Large Scale Study T2 - Zweitveröffentlichungen der Universität Potsdam : Humanwissenschaftliche Reihe N2 - This study investigates the relationship between teacher quality and teachers’ engagement in professional development (PD) activities using data on 229 German secondary school mathematics teachers. We assessed different aspects of teacher quality (e.g. professional knowledge, instructional quality) using a variety of measures, including standardised tests of teachers’ content knowledge, to determine what characteristics are associated with high participation in PD. The results show that teachers with higher scores for teacher quality variables take part in more content-focused PD than teachers with lower scores for these variables. This suggests that teacher learning may be subject to a Matthew effect, whereby more proficient teachers benefit more from PD than less proficient teachers.

New EMS devices offer a wide range of mobile applications for whole-body EMS (WB-EMS) training, e.g., the intensification of dynamic low-intensity endurance exercises through WB-EMS. The present study aimed to determine the differences in exercise intensity between WB-EMS-superimposed and conventional walking (EMS-CW), and CON and WB-EMS-superimposed Nordic walking (WB-EMS-NW) during a treadmill test. Eleven participants (52.0 ± years; 85.9 ± 7.4 kg, 182 ± 6 cm, BMI 25.9 ± 2.2 kg/m2) performed a 10 min treadmill test at a given velocity (6.5 km/h) in four different test situations, walking (W) and Nordic walking (NW) in both conventional and WB-EMS superimposed. Oxygen uptake in absolute (VO2) and relative to body weight (rel. VO2), lactate, and the rate of perceived exertion (RPE) were measured before and after the test. WB-EMS intensity was adjusted individually according to the feedback of the participant. The descriptive statistics were given in mean ± SD. For the statistical analyses, one-factorial ANOVA for repeated measures and two-factorial ANOVA [factors include EMS, W/NW, and factor combination (EMS*W/NW)] were performed (α = 0.05). Significant effects were found for EMS and W/NW factors for the outcome variables VO2 (EMS: p = 0.006, r = 0.736; W/NW: p < 0.001, r = 0.870), relative VO2 (EMS: p < 0.001, r = 0.850; W/NW: p < 0.001, r = 0.937), and lactate (EMS: p = 0.003, r = 0.771; w/NW: p = 0.003, r = 0.764) and both the factors produced higher results. However, the difference in VO2 and relative VO2 is within the range of biological variability of ± 12%. The factor combination EMS*W/NW is statistically non-significant for all three variables. WB-EMS resulted in the higher RPE values (p = 0.035, r = 0.613), RPE differences for W/NW and EMS*W/NW were not significant. The current study results indicate that WB-EMS influences the parameters of exercise intensity. The impact on exercise intensity and the clinical relevance of WB-EMS-superimposed walking (WB-EMS-W) exercise is questionable because of the marginal differences in the outcome variables.

Experimental methods have advanced significantly and can capture the dynamics of actin waves over a large range of spatio-temporal scales. However, the corresponding coarse-grained theory mostly avoids the full complexity of this multi-scale phenomenon. In this perspective, we focus on a minimal continuum model of activator–inhibitor type and highlight the qualitative role of mass conservation, which is typically overlooked. Specifically, our interest is to connect between the mathematical mechanisms of pattern formation in the presence of a large-scale mode, due to mass conservation, and distinct behaviors of actin waves.

Scientific and public audiences use them to describe political realities and to substantiate causal claims about those realities. This introduction to the thematic issue reviews the history of democracy measurement since the 1950s. It identifies four development phases of the field, which are characterized by three recurrent topics of debate: (1) what is democracy, (2) what is a good measure of democracy, and (3) do our measurements of democracy register real-world developments? As the answers to those questions have been changing over time, the field of democracy measurement has adapted and reached higher levels of theoretical and methodological sophistication. In effect, the challenges facing contemporary social scientists are not only limited to the challenge of constructing a sound index of democracy. Today, they also need a profound understanding of the differences between various measures of democracy and their implications for empirical applications. The introduction outlines how the contributions to this thematic issue help scholars cope with the recurrent issues of conceptualization, measurement, and application, and concludes by identifying avenues for future research.

BT - Eine Analyse deutschsprachiger Begriffe und Redewendungen zur Tabakentwöhnung T2 - Postprints der Universität Potsdam : Humanwissenschaftliche Reihe N2 - Hintergrund/Fragestellung: Während einer erfolgreichen Psychotherapie – so Miller und Rollnick (2013) – initiiert der Therapeut ein lautes Nachdenken über Veränderung (change talk), das eine Verhaltensänderung einleitet und verschiedene Facetten der Motivation eines Patienten spiegelt. Auf den preparatory change talk (desire, ability, reasons, need) folgt der mobilizing change talk (commitment, activation, taking steps) und schließlich die Verhaltensänderung. Die vorliegende Studie ist ein erster Versuch, deutsche Begriffe und Redewendungen zu analysieren, um Therapeuten die Einschätzung der Motivation eines Patienten zu erleichtern. Methodik: Das schrittweise Vorgehen entsprach weitgehend einem in der englischsprachigen Literatur beschriebenen Verfahren zur Einschätzung von Begriffen und Redewendungen hinsichtlich der Motivation eines Sprechers (vgl. Amrhein, 2009): (1) Generierung einer Sammlung relevanter Begriffe und Redewendungen, (2) Einschätzung der Stärke einer Formulierung durch 430 Probanden, (3) Bestimmung der Retestreliabilität anhand der Einschätzungen von 63 Probanden, (4) Kategorisierung von 140 Begriffen und Redewendungen durch drei Experten. Ergebnisse: Die ausgewählten Begriffe und Phrasen lassen sich zuverlässig den von Miller und Rollnick (2013) beschriebenen Kategorien Preparatory Change Talk oder Mobilizing Change Talk zuordnen, κ = .83 (95 % CI, .80 ≤ κ≤ .85), p < .001, und spiegeln darüber hinaus verschiedene Ausprägungen der Motivation eines Sprechers wider. Die Einschätzungen der Stärke einer Formulierung sind jedoch nicht stabil (Retestreliabilität: .21 ≤ rtt ≤.70). Schlussfolgerungen: Die Beachtung typischer Schlüsselwörter kann das richtige Timing einer Intervention erleichtern und darüber hinaus Auskunft über die „Entschlossenheit“ eines Patienten geben. Im Rahmen von Forschungsprojekten könnten auf der Basis erweiterter Sammlungen relevanter Begriffe und Redewendungen Algorithmen entwickelt werden, die eine Einschätzung der Motivation und damit prognostisch bedeutsame Aussagen erlauben. N2 - Background/Aim: According to Miller and Rollnick (2013), successful treatment for mental illness and substance abuse, respectively, involves change talk about client motivation. A complete conversation about motivation comprises both preparatory (desire, ability, reasons, need) and mobilizing change talk (commitment, activation, taking steps). The present study seeks to adopt a well-established English-language assessment instrument used to classify clients’ change talk. Method: Therefore, 150 German-language phrases reflecting motivation for change were presented to 430 volunteers and three experts in motivational interviewing. Results: Assignment of phrases to the distinct categories of change talk was highly reliable,κ = .83 (95 % CI, .80 ≤ κ ≤ .85), p < .001. Most phrases reflected a modest level of motivation. Test-retest reliabilities of strength ratings ranged from rtt = .21 to rtt = .70. Conclusions: Careful listening to specific phrases reflecting client motivation may enable counsellors to adopt interventions to clients’ level of motivation. Future research may seek to expand the data basis of linguistic analyses by including a wider range of German-language phrases. An increased item pool may facilitate the identification of terms and phases related to subsequent behaviour change.

However, information on wind effects on fine root morphology is scarce and the extent to which wind changes plant–soil interactions remains unclear. Therefore, we investigated the effects of two wind intensity levels by manipulating surrounding vegetation height in a grassland PSF field experiment. We grew four common plant species (two grasses and two non-leguminous forbs) with soil biota either previously conditioned by these or other species and tested the effect of wind on root:shoot ratio, fine root morphological traits as well as the outcome for PSFs. Wind intensity did not affect biomass allocation (i.e. root:shoot ratio) in any species. However, fine-root morphology of all species changed under high wind intensity. High wind intensity increased specific root length and surface area and decreased root tissue density, especially in the two grasses. Similarly, the direction of PSFs changed under high wind intensity in all four species, but differences in biomass production on the different soils between high and low wind intensity were marginal and most pronounced when comparing grasses with forbs. Because soils did not differ in plant-available nor total nutrient content, the results suggest that wind-induced changes in root morphology have the potential to influence plant–soil interactions. Linking wind-induced changes in fine-root morphology to effects on PSF improves our understanding of plant–soil interactions under changing environmental conditions.

Rotifers are an important component of aquatic ecosystems, and genetic variation is essential to their ongoing adaptive diversification and local adaptation. In addition to coding sequence divergence, variation in gene expression may relate to variable heat tolerance, and can impose ecological barriers within species. Temperature plays a significant role in aquatic ecosystems by affecting species abundance, spatio-temporal distribution, and habitat colonization. Recently described (formerly cryptic) species of the Brachionus calyciflorus complex exhibit different temperature tolerance both in natural and in laboratory studies, and show that B. calyciflorus sensu stricto (s.s.) is a thermotolerant species. Even within B. calyciflorus s.s., there is a tendency for further temperature specializations. Comparison of expressed genes allows us to assess the impact of stressors on both expression and sequence divergence among disparate populations within a single species. Here, we have used RNA-seq to explore expressed genetic diversity in B. calyciflorus s.s. in two mitochondrial DNA lineages with different phylogenetic histories and differences in thermotolerance. We identify a suite of candidate genes that may underlie local adaptation, with a particular focus on the response to sustained high or low temperatures. We do not find adaptive divergence in established candidate genes for thermal adaptation. Rather, we detect divergent selection among our two lineages in genes related to metabolism (lipid metabolism, metabolism of xenobiotics).

The first corpus analysis revealed that definiteness, givenness and type of referring expression influenced word order variation in child language and child-directed speech when the type of referring expression distinguished between pronouns and lexical noun phrases. These results correspond to previous child language studies in English (e.g., de Marneffe et al. 2012). Extending the scope of previous studies, our second corpus analysis examined the role of different pronoun types on word order. It revealed that word order in child language and child-directed speech was predictable from the types of pronouns used. Different types of pronouns were associated with different sentence positions but also showed a strong correlation to givenness and definiteness. Yet, the distinction between pronoun types diminished the effects of givenness so that givenness had an independent impact on word order only in child-directed speech but not in child language. Our results support a multi-factorial approach to word order in German. Moreover, they underline the strong impact of the type of referring expression on word order and suggest that it plays a crucial role in the acquisition of the factors influencing word order variation.

Diese räumen den autorisierten Autoren oder Einrichtungen bestimmte Open-Access-Rechte zur Zweitveröffentlichung ein. Vorhandene Lizenzrechte zur Realisierung des Grünen Weges können somit zukünftig verstärkt genutzt werden. Dabei kann die Bibliothek eine aktive Rolle einnehmen. Präsentiert wird ein Workflow, der sich an der Checkliste für Repository-Manager orientiert. Sieben herausgearbeitete Schritte werden genannt und näher erläutert. An Beispielen wurde der Workflow getestet. Die Ergebnisse werden ebenfalls vorgestellt. Die Erweiterung des Workflows zur Identifizierung von Publikationen für die Zweitveröffentlichung lässt sich ggf. auch auf Creative-Commons-Lizenzen anwenden bzw. auf Zeitschriften, die keine Open-Access-Komponente haben. N2 - Available alliance and national licences may contain an Open Access component. They grant authorised authors or institutions certain Open Access rights for secondary publication. Existing licence rights for realising the Green Road can be used to an increased extent in the future, and the library can play an active role. This article presents a workflow that is oriented towards the check-list for repository managers. It cites seven steps that have been identified and gives more details about them. The workflow has been tested on examples, the results are presented as well. The extension of the workflow for identifying works for secondary publication may perhaps be applicable on Creative Commons licences or magazines that do not have an Open Access component.
