Agricultural soils can act as a carbon sink depending on the soil management practices employed. As a result of this functional duality, soil management systems are present in international documents relating to climate change mitigation. Agricultural practices are responsible for 14% of total greenhouse gas emissions (GHG’s) (MMA, 2009)(1). Conservation agriculture (CA) is one of the most effective agricultura...
The study aimed to evaluate tear production by means of modified Schirmer tear tes-1 (mSTT-1) in neonate cats. Likewise, correlation between mSTT-1 and STT-1 was assessed in vitro. Standard SST strips were cut in half and after eye lid opening, tear production of neonates (n=15) was daily measured in both eyes (mSTT-1), until the 7th day, and at day 14, 21, and 28. Animals were daily weighted until 28 days of a...
Internationalisation has become increasingly important for the vi- ability of business organizations. The engagement of domestic com- panies in international business is regarded as determinant for the competitiveness of developed and developing countries. In the last decade several countries launched public measures to encourage inter- nationalisation through foreign direct investment. Policy makers are increa...
Firms competencies and needs may determine movements to foreign locations. Firms may use their own resources to establish or maintain activities of foreign direct investment, or otherwise when internal resources are insu cient they may apply for external support provided by governments. With a binary probit model applied on a recent survey, a Bayesian lter calculates the probability of a given characteristic's...
An interesting debate is now taking place among scholars and policy makers about the value of public support for internationalization activities. These incentives have been applied in many countries to stimulate not only the exports but also foreign direct investments, but the results are not clear. Governments must ensure that beyond the increase of a country's competitiveness, public support also will promote...
In particularly in times of budget constraints governments should analyze in detail all aspects related to the implementation of their public support to enterprises. With an Heckman selection model and data collected through a survey to Portuguese firms, we test which variables may affect awareness and use of the public support to internationalization. The results show that firms’ competencies positively affect...
An interesting debate is currently taking place among scholars and decision makers about the evaluation of public support targeted to internationalization activities. In order to understand their efficiency, we need first to know more about the determinants of their use. We developed an econometric model based on the Heckmam method, a two-step statistical approach that corrects for selection bias resulting from...
It has long been believed that typical students learn better through contemporary approaches to questions originated by physics problems that allow experiments. This belief motivated us to develop interactive computational didactic materials about contemporaneous mathematics that can be used both in the classroom and in mathematics clubs in school. Dynamical Systems, the study of how physical systems evolve wit...
