This chapter presents research conducted in early childhood classrooms in Luxembourg, a European country with a complex multilingual situation. A multi-layered corpus of classroom interactions, consisting of photos, videos and audio recordings, was collected over a period of 6 months and then classified, annotated and partially transcribed. Drawing from this corpus, this study sheds light on the discursive practices of 6-12 year old children and examines the co-construction of the children’s growing understandings of science in collaborative inquiries. Arguing from a context-sensitive perspective, our research approaches the learning of science as an interactional achievement in situ, one that encompasses the enactment of science as shared discourse and therefore as a cultural accomplishment.

‘Day-care-childhoods’ are not only performed in the confined spaces of certain kinds of day care facilities as ethnographic research on Early Childhood Education and Care (ECEC) often suggests. Rather, parents combine diverse settings to more or less complex chains of care arrangements. Particularly, in the case of Luxembourg, ECEC is divided into a sector of care and a sector of education that parents combine. Observed from the ‘vantage point’ of children, these care-arrangements cause various horizontal transitions during the course of a child’s day/week and therefore create distinct spaces of positioning and actorship. The spatiality of care-arrangements is shaped by patterns of mobility as well as the strength of enacted borders between the diverse settings, which the children have to cross on a daily basis. The Luxembourgian CHILD-Study traces those border-crossing-practices of children in ECEC that manifest as the ‘localized connections’ of ECEC-policies, familial care strategies and organizational routines. From a practice-analytical view this study asks: How do young children (age 2-4) actively participate in socio-material practices of setting up and crossing borders and create diverse spaces of ECEC? The presentation will introduce the welfare-theoretical perspective and the practice-analytical approach of the study and present the analyses of two ethnographic case studies on children’s care-arrangements and their respective spatial practices and border-crossings.

In mobile robotic applications, a common problem is the following of a given trajectory with a constant velocity. Using standard model predictive control (MPC) for tracking of time varying trajectories leads to a constant tracking error. This problem is modelled in this paper as quadrotor position tracking problem. The presented solution is a computationally light-weight target position control (T PC), that controls the tracking error of MPCs for constantly moving targets. The proposed technique is assessed mathematically in the Laplace domain, in simulation, as well as experimentally on a real quadrotor system. [less ▲]

The version 2.0 of Tractor_DB is now accessible at its three international mirrors: www.bioinfo.cu/Tractor_DB, www.tractor.lncc.br and http://www.ccg.unam.mx/tractorDB. This database contains a collection of computationally predicted Transcription Factors' binding sites in gamma-proteobacterial genomes. These data should aid researchers in the design of microarray experiments and the interpretation of their results. They should also facilitate studies of Comparative Genomics of the regulatory networks of this group of organisms. In this paper we describe the main improvements incorporated to the database in the past year and a half which include incorporating information on the regulatory networks of 13-increasing to 30-new gamma-proteobacteria and developing a new computational strategy to complement the putative sites identified by the original weight matrix-based approach. We have also added dynamically generated navigation tabs to the navigation interfaces. Moreover, we developed a new interface that allows users to directly retrieve information on the conservation of regulatory interactions in the 30 genomes included in the database by navigating a map that represents a core of the known Escherichia coli regulatory network.

Experimental data on the Escherichia coli transcriptional regulatory system has been used in the past years to predict new regulatory elements (promoters, transcription factors (TFs), TFs' binding sites and operons) within its genome. As more genomes of gamma-proteobacteria are being sequenced, the prediction of these elements in a growing number of organisms has become more feasible, as a step towards the study of how different bacteria respond to environmental changes at the level of transcriptional regulation. In this work, we present TRACTOR_DB (TRAnscription FaCTORs' predicted binding sites in prokaryotic genomes), a relational database that contains computational predictions of new members of 74 regulons in 17 gamma-proteobacterial genomes. For these predictions we used a comparative genomics approach regarding which several proof-of-principle articles for large regulons have been published. TRACTOR_DB may be currently accessed at http://www.bioinfo.cu/Tractor_DB, http://www.tractor.lncc.br/ or at http://www.cifn.unam.mx/Computational_Genomics/tractorDB.

This paper discusses a trade model with many countries, many goods produced in multiple quality versions, and non-homothetic preferences. It embeds in the same model a series of results that have been empirically confirmed: high-income countries specialize in the production of high-quality goods and trade more of those. Richer countries purchase more high-quality varieties. They import more high-quality products from the most productive exporters. The paper then studies the impact of productivity and population changes on the quality composition of exports. It finally explains why countries import higher quality goods from more distant countries. [less ▲]

This paper provides evidence that production linkages, as well as credit chains (represented by trade credit), are important for the transmission of idiosyncratic (firm-level) shocks across firms in the economy. We build on the idea that trade credit develops along production linkages, and amplifies the idiosyncratic shock as firms may lack inputs and also liquidity. Using disaggregated firm-level data we show that the disturbance of customer's sales increases with greater trade credit linkage. We show that during a recession the existence of trade credit linkage propagates shocks upstream, from a supplier onto its upstream customer. In these periods, firms are short of liquidity and are unable to withstand a drop in trade credit provision. In good times, however, trade credit plays a stabilizing role, reducing the volatility of firms' sales. In these periods, firms with sufficient liquidity are able to transfer some of it to liquidity-starved production partners in order to guarantee their own stable production. [less ▲]

We study the ever more integrated and ever more unbalanced trade relationships between European countries. To better capture the complexity of economic networks, we propose two global measures that assess the trade integration and the trade imbalances of the European countries. These measures are the network (or indirect) counterparts to traditional (or direct) measures such as the trade-to-GDP (Gross Domestic Product) and trade deficit-to-GDP ratios. Our indirect tools account for the European inter-country trade structure and follow (i) a decomposition of the global trade flow into elementary flows that highlight the long-range dependencies between exporting and importing economies and (ii) the commute-time distance for trade integration,which measures the impact of a perturbation in the economy of a country on another country, possibly through intermediate partners by domino effect. Our application addresses the impact of the launch of the Euro. We find that the indirect imbalance measures better identify the countries ultimately bearing deficits and surpluses, by neutralizing the impact of trade transit countries, such as the Netherlands. Among others, we find that ultimate surpluses of Germany are quite concentrated in only three partners. We also show that for some countries, the direct and indirect measures of trade integration diverge, thereby revealing that these countries (e.g. Greece and Portugal) trade to a smaller extent with countries considered as central in the European Union network.
