Multinational companies , technology spillovers , and plant survival
This paper examines the effect of the presence of multinational companies on plant survival in the host country. We postulate that multinational companies can impact positively on plant survival through technology spillovers. We study the nature of the effect of multinationals using a Cox proportional hazard model which we estimate using plant level data for Irish manufacturing industries. Our ...
متن کاملSurvival of Plant Tissue at Super-Low Temperatures. IV. Cell Survival with Rapid Cooling and Rewarming.
Thin unmounted cortical tissue sections from winter twigs of the mulberry tree were held with a thin forceps and rapidly immersed in liquid nitrogen from room temperatures without prefreezing. They were rewarmed; rapidly in water at 10 degrees to 40 degrees , or slowly, in air at room temperatures. In those sections rapidly rewarmed, all survived. None survived in those sections rewarmed slowly...
متن کاملPlant circadian clocks increase photosynthesis, growth, survival, and competitive advantage.
Circadian clocks are believed to confer an advantage to plants, but the nature of that advantage has been unknown. We show that a substantial photosynthetic advantage is conferred by correct matching of the circadian clock period with that of the external light-dark cycle. In wild type and in long- and short-circadian period mutants of Arabidopsis thaliana, plants with a clock period matched to...
متن کاملNatural Disasters, Industrial Clusters and Manufacturing Plant Survival
In this paper, we examine the role of industrial clusters and infrastructure in mitigating or magnifying the impact of the 1995 Kobe earthquake on the survival of manufacturing plants and their post-earthquake economic performance. Our methodological approach is to use information on building-level and infrastructure damages and other plant and buildingcharacteristics including district-level v...
متن کاملAssessing the survival of exogenous plant microRNA in mice
MicroRNAs (miRNAs), a class of small RNAs, are important molecules that influence several developmental processes and regulate RNA interference (RNAi), and are abundant in animals, plants, and plant tissues that are traditionally consumed in the diet. The survival of plant small RNAs from the diet in animals, however, remains unclear, and the persistence of miRNAs from dietary plants in the ani...
