In aktuellen Intelligenzstrukturmodellen gehört kristalline Intelligenz (gc) zu den am besten etablierten Fähigkeitsfaktoren. Dabei spiegelt gc die Einflüsse von Lernen und Akkulturation wider und umfasst somit alles Wissen, das Menschen im Laufe ihres Lebens erwerben und zum Problemlösen einsetzen. In diesem Beitrag beschreiben wir die Entwicklung einer Kurzskala zur Messung kristalliner Intelligenz mit fünfminütiger Bearbeitungszeit, die auf deklarativen Wissensfragen aus den Natur-, Geistes- und Sozialwissenschaften ...
Weak and strong bi-material interfaces and their influence on propagating cracks in plane elastic structures
The developing crack paths in heterogeneous structures are the result of the inhomogeneous state of stress. The latter stems from e.g. voids or inclusions in an elastic matrix, which are bonded either by strong or weak interfaces. Besides the stiffness of an inclusion, the kind of interface has a decisive influence on the state of stress and therefore on propagating cracks. It is experimentally proven that cracks tend to grow towards regions with lower stiffness (Tilbrook et al., 2006; Judt et al., 2015), therefore ...
Die Zeiten ändern sich. Zur Verwendung des imparfait in narrativen Kontexten
Using the imparfait in narrative contexts seems to contradict the imperfective aspect of the form, as the perfective aspect seems far more adequate in these contexts. In order to understand the effects of this usage, the imparfait narrative is considered on two levels: on the linguistic level of the French language and its aspect system, and on a text level that embraces the cultural discourse traditions that characterise different text types and genres. On the linguistic level, the imparfait is first contrasted to ...
Automatic Time Series Segmentation as the Basis for Unsupervised, Non-Intrusive Load Monitoring of Machine Tools
Detailed energy monitoring and benchmarking at the individual component level is necessary to increase energy efficiency in complex production systems. Non-intrusive load monitoring (NILM) provides an economical solution for operational state detection and load disaggregation without the need for large-scale use of fine-grained energy meters. Existing supervised NILM approaches require detailed training data including control information about individual devices. Unsupervised approaches, on the other hand, often ...
Adapting Kano's Theory for weighting and implementing customers requirements on a software tool for assessing human reliability in manual assembly
The following paper illustrates the conception of an Excel-based software tool developed to predict human error probabilities in manual assembly lines. In this regard, the paper clearifies how reliable risk analyses of manual work tasks can be carried out with the help of a software tool. Furthermore, to initiate a high user-friendliness, a high acceptance and a high level of dissemination, this paper deals with a Kano survey concerning customer requirements on the developed software tool. As a result, it will be ...
Name-informing and distancing sogenannt ‘so-called’: Name mentioning and the lexicon-pragmatics interface
This paper aims at a unified analysis of the different interpretations which constructions involving the German name-mentioning modifier soge-nannt‘so-called’ can adopt. In contrast to nouns like Sepsis‘sepsis’, a noun like Hotel ‘hotel’, as insogenanntes Hotel, gives rise to a “distanced” interpretation of the construction rather than one informing about a concept’s name. After a thorough investigation of the lexical-semantic properties, we propose the reading of the construction to emerge from an interplay between ...
Process and utility systems integration and optimisation for ultra-low energy milk powder production
This study applies a Total Site Heat Integration approach in conjunction with a detailed process and utility model, to develop an innovative ultra-low energy milk powder plant design. The basis for the analysis is a state-of-the-art modern milk powder plant that requires 5265 MJ/tp of fuel and 210.5 kWh/tp (58.5 MJe/tp) of electricity. The model of the modern milk powder plant was validated against industrial data and changes to process and/or utility systems are targeted and implemented into the model to understand ...
Untergangsphantasien/-diskurse: Goll, Céline, Gracq, Houellebecq
Aktuelle Themen wie das des lateinischen Reichs laden dazu ein, sie nach Maßgabe sachlicher, historisch-politischer Voraussetzungen zu diskutieren. Der vorliegende Beitrag versucht unter dem Stichwort Untergangsphantasien nichtsdestoweniger einen Schritt zurückzutreten und das diskursive, narrative Feld zu klären, in dem solche Diskussionen beheimatet sind.
Role of Pseudouridine Formation by Deg1 for Functionality of Two Glutamine Isoacceptor tRNAs
Loss of Deg1/Pus3 and concomitant elimination of pseudouridine in tRNA at positions 38 and 39 (ψ38/39) was shown to specifically impair the function of tRNAGlnUUG under conditions of temperature-induced down-regulation of wobble uridine thiolation in budding yeast and is linked to intellectual disability in humans. To further characterize the differential importance of the frequent ψ38/39 modification for tRNAs in yeast, we analyzed the in vivo function of non-sense suppressor tRNAs SUP4 and sup70-65 in the absence ...
Determinants of participation in rural non-farm economy in Zvimba District, Zimbabwe
The capacity of agriculture to provide sustainable livelihood opportunities is exceeded by the rural populations of developing countries, and with limited opportunities available in urban centres, the rural non-farm economy (RNFE) becomes pivotal in improving rural livelihoods. Within an empowerment agenda, it is important for policy makers to understand why households enter into the RNFE. We investigated participation in the RNFE of farm worker livelihoods along with the motivation for participation in RNF employment. ...
