International Trade and Restructuring in Eastern Europe

It has been widely recognized that international economic relations play a crucial role in the transition of countries of Eastern and Central Europe. The scope, speed, and success of the efforts to transform the formerly centrally planned economies to market economies have increasingly become dependent on the pattern these countries have in their relation to the rest of the world. Many of the new governments in these countries have found that the most appropriate fixed point (the so-called nominal anchor), to which stabilization measures should be attached, is the nominal exchange rate of their currency. A more reasonable exchange rate than that in the former system of central planning has required a full system of reorganization of trade and exchange relations including the establishment of some kind of currency convertibility and deregulation of international trade transactions. Part I of the book deals with exchange rate regimes that have played and may play a role in supporting political and macroeconomic stabilization, on the one hand, and competitiveness of domestic production, on the other. For foreign trade the structural changes had two implications: (1) shift in the sectoral and geographical composition of trade and (2) the modification of the behavior of enterprises. Part II of the book covers the first dimension and Part III is devoted to the changes in trade-related enterprise behavior

Extending the Interaction Flow Modeling Language (IFML) for Model Driven Development of Mobile Applications Front End

International audienceFront-end design of mobile applications is a complex and multidisciplinary task, where many perspectives intersect and the user experience must be perfectly tailored to the application objectives. However, development of mobile user interactions is still largely a manual task, which yields to high risks of errors, inconsistencies and ine ciencies. In this paper we propose a model-driven approach to mobile application development based on the IFML standard. We propose an extension of the Interaction Flow Modeling Language tailored to mobile applications and we describe our implementation experience that comprises the development of automatic code generators for cross-platform mobile applications based on HTML5, CSS and JavaScript optimized for the Apache Cordova framework. We show the approach at work on a popular mobile application, we report on the application of the approach on an industrial application development project and we provide a productivity comparison with traditional approaches

Preference for pasture versus freestall housing by dairy cattle when stall availability indoors is reduced

Providing cattle with access to pasture has been shown to yield benefits, including access to more space, fewer agonistic interactions, better air quality, and the ability to perform a greater range of normal behaviors. Preference for pasture appears to depend on several parameters, including weather conditions and availability of shade. The primary aim of this study was to evaluate the preference for pasture versus inside a freestall barn with variable stocking densities at the stalls. We also investigated the effect of temperature-humidity index (THI) and precipitation on this preference. Overall, cows spent on average 13.7 ± 2.6 h/d (mean ± SD) on pasture (ranging from 7.2 to 18.0 h/d across days); at night (between 2000 and 0600 h) cows spent the majority of their time (78.5 ± 27.8%) on pasture. Stall availability had no effect on time spent outside, but time spent on pasture decreased with increasing THI during the day and declined during nights with more rainfall. Stall usage changed depending on stall availability; standing with 2 and 4 feet in the stall and lying time indoors decreased with decreasing stall availability. Indoor lying time also increased with higher THI and more precipitation. In conclusion, cows preferred to be outside at night; they were much more likely to remain indoors during the day, even when overstocked
