The influence of temperature on teliospore germination and basidiospore formation in Gymnosporangium juniperi-virginianae was studied in vitro. Teliospores germinated from 8 to 30 °C. Germination was first observed after 2 h from 12–28 °C but longer periods were required at lower temperatures. Promycelia formed basidiospores by 4 h from 12 to 24 °C but not until 7 h at 8 °C. Abortive germination of teliospores, without production of basidiospores, occurred from 26 to 30 °C. No germination was observed from 2 to 6 °C. Multiple regression analyses were performed and an equation relating germination of teliospores to temperature and time was formulated.

A través de aproximaciones empíricas apoyadas en el modelo de crecimiento de Paul Romer y de la función de producción neoclásica tipo Cobb-Douglas, este trabajo incluye los factores propios de estos modelos a través de externalidades de capital para explicar el crecimiento económico en México. Se realizó un modelo de regresión de efectos fijos en el tiempo, empleando datos longitudinales para el período 2003-2008. Se concluye que el parámetro tecnológico es determinante para explicar el crecimiento del PIB mexicano, esto es, que la proporción de población con estudios superiores terminados influye directamente en el crecimiento económico del país. Las inversiones en ciencia y tecnología por parte de los estados mexicanos resultaron no significativas dentro del experimento realizado.Through empirical approaches supported in the growth model of Paul Romer and neoclassical production function Cobb-Douglas, this work includes specific factors such as externalities capital models to explain economic growth in Mexico. A panel data was constructed for 2003-2008 and a fixed-time-effects regression model applied. It is concluded that technological parameter is crucial for the growth of Mexican GDP, that is, the proportion of population with university degree directly affects economic growth. Investments in science and technology made by mexican states were not significatives within the experiment performed.

This study investigates the impact of Ease of Doing Business on Inward FDI over the period from 2011 to 2015 across the globe. This study measures ease of doing business using starting a business, getting credit, registering property, paying taxes and enforcing contracts. The research used a sample of 177 countries from 190 countries listed in World Bank. Least square regression model via E-views software used to examine causal relationship. The study found that ease of doing business indicators ‘Enforcing Contracts’ was found to have a positive significant impact on Inward FDI. Nevertheless, ‘Getting Credit’ and ‘Registering Property’ were found to have a negative significant impact on Inward FDI. However, ‘Starting a Business’ and ‘Paying Taxes’ have no significant impact on Inward FDI in the studied timeframe of this research. The findings of the study suggested the ease of doing business enables inward FDI through better contract enforcements, getting credit and registering property. The findings of the research will assist international managers and companies to know the importance of ease of doing business when investing in foreign countries through FDI.
