Produktivitätssteigerungen mit dem Manufacturing-Execution-System MR-CM© JF - HMD - Praxis der Wirtschaftsinformatik N2 - Manufacturing-Execution-Systeme (MES) werden in der Fertigungsindustrie dazu eingesetzt, einen durchgehenden Informationsfluss zwischen den an der Fertigung beteiligten Systemen herzustellen. Von der Vernetzung aller an der Produktion beteiligten Systeme wird dabei eine gesteigerte Produktivität auf Shop-Floor-Ebene erwartet. Beim Durchlauf des beispielhaft gezeigten Fertigungsauftrages wurden durch den Einsatz von MR-CM©, einem von der Maschinen-fabrik Reinhausen entwickelten und implemen-tierten MES, bereits einige Produktivitätspotenziale im Vergleich mit der konventionellen Abwicklung ohne Einsatz des MES deutlich. Diese resultieren im Wesentlichen aus der Eliminierung von nicht wertschöpfenden Schnittstellenproblemen zwischen den an der Auftragsdurchführung beteiligten Maschinen. Die erzielten Produktivitätszuwächse bestehen im Kern aus einer Verkürzung der Maschinenrüstzeiten, was zu einer Reduktion der Produktionskosten und einer Zunahme der Produktionsflexibilität führt und zu einer Reduzierung der Werkzeugbestände sowie der damit verbundenen Kapitalbindungskosten.

Colloidal core templates consisting of styrene/acrylate latex particles were coated with multilayers of polycondensate-based dispersants commonly used in concrete. This way, core–shell particles possessing both dispersing and film-forming properties were achieved. Incorporation of the latex@dispersant hybrid additive into a cement paste results in a slow release of the dispersant which instigates prolonged plastification of the cement slurry. Following disintegration of the shell, the latex core particles are released into the pore solution and coalesce into a polymer film which improves the mechanical properties of the hardened cement. Characterization of the templates and novel additives plus tracking of the layer-by-layer polyelectrolyte adsorption was performed by means of zeta potential measurement, dynamic light scattering and electron microscopy. Our method allows to synthesize multifunctional additives with time-controlled release effect.

This finding is termed retrieval-induced forgetting (RIF) and is assumed to be the consequence of an inhibitory mechanism resolving retrieval competition. In the present study, we examined brain oscillatory processes related to RIF, as induced by competitive memory retrieval. Contrasting a competitive with a noncompetitive retrieval condition, we found a stronger increase in early evoked theta (4–7 Hz) activity, which specifically predicted RIF, but not retrieval-induced enhancement. Within the cognitive framework of RIF, these findings suggest that theta oscillations reflect arising interference and its resolution during competitive retrieval in episodic memory.

T1 - Retrieval-induced forgetting in young children JF - Psychonomic Bulletin & Review N2 - A prominent theory of cognitive development attributes the poor performance that children show in many cognitive tasks to a general lack of inhibitory control. We tested this theory by examining children’s inhibitory capabilities in retrieval-induced forgetting (RIF), a memory task in which selective retrieval of previously studied material causes forgetting of related, nonretrieved material. Such forgetting is often attributed to inhibitory control processes, which supposedly suppress the nonretrieved items’ memory representation. We examined RIF in kindergartners, second graders, and adults, using both recall and recognition testing. Although all three age groups showed significant RIF in recall, only adults and second graders, but not kindergartners, showed RIF in recognition. Because inhibition-based RIF should be present in recall and recognition, these findings indicate that in adults and second graders, but not in kindergartners, RIF is mediated by inhibition. The results support the view of inefficient inhibitory processes in young children’s cognition.

T1 - Working memory capacity predicts listwise directed forgetting in adults and children JF - Memory N2 - In listwise directed forgetting, participants are cued to forget previously studied material and to learn new material instead. Such cueing typically leads to forgetting of the first set of material and to memory enhancement of the second. The present study examined the role of working memory capacity in adults' and children's listwise directed forgetting. Working memory capacity was assessed with complex span tasks. In Experiment 1 working memory capacity predicted young adults' directed-forgetting performance, demonstrating a positive relationship between working memory capacity and each of the two directed-forgetting effects. In Experiment 2 we replicated the finding with a sample of first and a sample of fourth-grade children, and additionally showed that working memory capacity can account for age-related increases in directed-forgetting efficiency between the two age groups. Following the view that directed forgetting is mediated by inhibition of the first encoded list, the results support the proposal of a close link between working memory capacity and inhibitory function.

T1 - Directed forgetting in young children: Evidence for a production deficiency JF - Psychonomic Bulletin & Review N2 - When people are cued to forget a previously studied list of items and to learn a new list instead, such cuing typically leads to forgetting of the first list and to memory enhancement of the second. In two experiments, we examined such listwise directed forgetting in children (and adults), using a forget cue that placed either high emphasis or low emphasis on the need to forget. In the low-emphasis condition, (adult-like) List 1 forgetting was present in fourth graders, but not in first graders (and kindergartners); in contrast, in the high-emphasis condition, (adult-like) List 1 forgetting was present from first grade on. Only fourth graders showed (adult-like) List 2 enhancement, regardless of task instruction. The finding that first graders showed List 1 forgetting only in the high-emphasis condition points to a production deficiency in first graders’ directed forgetting, suggesting that the children are capable of intentional forgetting but fail to do so spontaneously. The finding that first graders showed List 1 forgetting without List 2 enhancement suggests that the two directed-forgetting effects are mediated by different processes with different developmental trajectories.
