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 ...

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 ...

This study was conducted to examine the growth and immune performance of catfish (Clarias gariepinus) juveniles cultured in a biofloc fish farming system. To achieve this, 900 C. gariepinus juveniles (9.0 ± 0.23 g) were cultured in an intensive zero water exchange biofloc system for 72 days in 9 separate tanks (2 m3 each) aerated by an air blower, after which growth assessment of fish was conducted. The trial consisted of three treatments in triplicates, a control without carbon source addition, and two biofloc ...

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 ...

Empirisches Denken und damit Kenntnisse in erfahrungswissenschaftlicher Forschungsmethodik sind im Wesentlichen für drei Bereiche der Pädagogik bedeutsam: (1) beim Betreiben von erziehungswissenschaftlicher Forschung und beim kritischen Rezipieren von Forschungsbefunden durch pädagogische Praktiker, die ihr professionelles Handeln weitestgehend auf gesichertes Wissen gründen wollen, (2) bei der praktischen Erziehungs- und Unterrichtstätigkeit zur Vermeidung von voreiligen Schlüssen aus Praxiserfahrungen für ...

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 ...

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 ...

Maize (Zea mays) is an important food and cash crop of uplands in Southeast Asia, where it is often prone to drought and heat stress associated with climate change. This study aimed at assessing the effect of heat and drought on maize performance, testing coping strategies under such weather extremes, and understanding associated mechanisms. The experiment was carried out during 2018 in Thailand, using a split-plot design with three replications. Treatments were: July-planted maize sole cropping (control), July-planted ...

Low iodine content in soils is a common feature in lowland and in mountainous regions far from oceans. The diets of the people living in these regions are often deficient in dietary iodine, resulting in chronic iodine deficiency syndrome, goiter, hearing loss and other debilitating diseases. A field experiment was conducted at the Teaching and Research Farm, University of Ilorin, Nigeria during the 2017 and 2018 cropping seasons, to evaluate the response of amaranths to iodine enrichment using an agronomic approach. ...
