The relationship between terms-of-trade and trade balance in ASEAN-5

This study examines the relationship between career strategies and career success. The three dimensions that measured career strategies were enhancing promotability, strengthening external contacts, and improving image with superiors. Meanwhile, the dimension that measured career success was subjective career success. Data were gathered through the distribution of questionnaires to employees at a manufacturing organization (n=185). Correlation and regression analysis were used to examine the relationship between career strategies and career success. The results indicated that there were no relationships between overall career strategies and career success. However, in terms of career strategies dimensions, only two were positively correlated with career success, namely, strengthening external contacts and improving image with superiors. The multi-regression results suggest that improving image with superiors was the most important factor in influencing individual’s career success. The findings were discussed and recommendations for future research were also put forward

Wide-address spaces - exploring the design space

In a recent issue of Operating System Review, Hayter and McAuley [1991] argue that future high-performance systems trade a traditional, bus-based organization for one where all components are linked together by network switches (the Desk-Area Network). In this issue of Operating System Review, Leslie, McAuley and Mullender conclude that DAN-based architectures allow the exploitation of shared memory on a wider scale than just a single (multi)processor. In this paper, we will explore how emerging 64-bit processors can be used to implement shared address spaces spanning multiple machines

SUNK COSTS HYSTERESIS IN SPANISH MANUFACTURING EXPORTS

This paper tests the sunk costs explanation for hysteresis in exports using a sample of Spanish manufacturing firms for the period 1990-2000. The data are drawn from the Spanish Encuesta sobre Estrategias Empresariales. To obtain consistent estimates for sunk costs, we control for all other sources of persistence and use a dynamic random effects multivariate probit model that is estimated through pseudo simulated maximum-likelihood techniques. Our results support the sunk costs explanation for hysteresis. Furthermore, regional spillovers and some firm characteristics such as size, productivity or vertical and horizontal product differentiation are found to have a significant influence on the probability of exporting. El objetivo de este artículo es analizar el papel de los costes irrecuperables como factorexplicativo de la histéresis de las exportaciones. Para ello se hace uso de una muestra deempresas industriales españolas para el período 1999-2000, que proviene de la Encuestasobre Estrategias Empresariales. Con el objetivo de obtener estimaciones consistentespara los costes irrecuperables, controlamos por todas las posibles fuentes alternativas depersistencia y estimamos nuestro modelo usando técnicas de pseudo máximaverosimilitud simulada. Nuestros resultados confirman a los costes irrecuperables comocausante de la histéresis de las exportaciones. Adicionalmente, encontramos que lasexternalidades regionales y algunas características empresariales tales como tamaño,productividad o diferenciación horizontal y vertical tienen un impacto significativosobre la probabilidad de exportar.Histéresis de las exportaciones, costes irrecuperables, modelos dinámicos de elección discrecional hysteresis in trade, sunk costs, dynamic discrete choice models

Oak Persistence in Mediterranean Landscapes: The Combined Role of Management, Topography, and Wildfires

Mediterranean ecosystems have been shaped by a history of human and ecological disturbances. Understanding the dynamics of these social-ecological systems requires an understanding of how human and ecological factors interact. In this study, we assess the combined role of management practices and biophysical variables, i.e., wildfire and topography, to explain patterns of tree persistence in a cork oak (Quercus suber L.) landscape of southern Portugal. We used face-to-face interviews with landowners to identify the management practices and the incentives that motivated them. We used aerial photographs and a Geographic Information System (GIS) to classify vegetation patch-type transitions over a period of 45 years (1958-2002) and logistic regression to explain such changes based on management and biophysical factors. The best model explaining vegetation transitions leading to cork oak persistence in the landscape included both biophysical and management variables. Tree persistence was more likely to occur on steeper slopes, in the absence of wildfires, and in the absence of understory management. We identified ecological, ideological, and economical barriers that preclude oak persistence and that are important to consider in implementing efficient environmental policies for adequate conservation and reforestation programs of Mediterranean cork oak landscape
