Desarrollo de metodologias de propagación y cultivo de plantas nativas de Córdoba con potencialornamental. Development of propagation and cultivation methodologies of native plants of Córdoba withornamental potential.

El problema: La flora nativa de Córdoba, actualmente amenazada, es rica en especies con potencial ornamental que todavía no se cultivan. El uso de estas plantas está limitado por la escasez de material biológico, la falta de conocimientos de su propagación y su insuficiente valoración pública. Hipótesis: La propagación y el cultivo de una amplia gama de plantas nativas cordobesas con potencial ornamental son técnicamente factibles y tienen potencial productivo y económico. Objetivo: Promover el uso de especies nativas ornamentales en la provincia de Córdoba. Objetivos específicos: 1. Desarrollar metodologías de propagación y cultivo de especies nativas con potencial ornamental; 2. Transferir estas metodologías a viveros privados y públicos; 3. Difundir los conocimientos obtenidos a instituciones educativas. Métodos: 1- Colección: Se realizarán viajes de campo para obtener semillas o esquejes de al menos 6 especies nativas seleccionadas. Las semillas se limpiarán y se conservarán en frío. 2- Propagación: En la primavera se sembrarán 100 semillas por especie, accesión y tratamiento; se registrará porcentaje y tiempo de germinación. Los plantines se trasplantarán a almácigos, se registrará supervivencia y crecimiento. Para la propagación vegetativa, se trasplantarán esquejes de estolones directamente a macetas. 3- Trasplante: En verano, los plantines se trasplantarán a macetas grandes; se registrará supervivencia y crecimiento durante un año. 4- Documentación: Se elaborarán protocolos de las metodologías adecuadas para la propagación de las especies, usos ornamentales y características relevantes. 5- Transferencia: Los protocolos, muestras de semillas y de plantas, se transferirán a dos viveros que se comprometan a continuar con el cultivo de las especies. 6- Difusión: Se realizarán cursos, talleres, charlas y pasantías para dar a conocer la propagación de plantas nativas en instituciones educativas, desde la primaria hasta la universidad. Resultados y productos esperados: 1- Protocolos de propagación de al menos 6 especies nativas ornamentales y su transferencia a viveros, como base de una actividad productiva novedosa. 2- Un aporte a la conservación ex situ y el uso sostenible de la flora nativa. 3- Una mayor valoración de esta en la comunidad educativa. Importancia: 1- Desarrollo de la producción de plantas nativas con valor ornamental, como una alternativa económica. 2- Conservación ex situ y uso sostenible de la flora nativa. 3- Difusión del conocimiento del valor ornamental de las nativas. 4. Información científica de la biología y ecología de especies nativas. Pertinencia: Productos (ver Resultados). El impacto inmediato esperado es un aumento en la propagación, la producción, la demanda, la comercialización y el uso de plantas ornamentales nativas. Se espera también la generación de nuevos conocimientos y el estímulo de líneas de investigación biológicas y agronómicas.

Conceptual Foundations of Modelling of Innovative Production Projects

At the moment there is a lack of methodological approaches to formalization of management of innovative projects relating to production systems, as well as to adaptation and practical use of the existing approaches. This article is about one potential approach to the management of innovative projects, which makes the building of innovative process models possible based on objective approach. It outlines the frameworks for the building of innovative project models, and describes the method of transition from conceptual modelling to innovative project management. In this case, the model alone and together with parameters used for evaluation of the project may be unique and depends on the special features of the project, preferences of decision-making person, and production and economic system in which it is to be implemented. Unlike existing approaches, this concept does not place any restrictions on types of models and makes it possible to take into account the specificities of economic and production systems. Principles embodied in the model allow its usage as a basis for simulation model to be used in one of specialized simulation systems, as well as for information system providing information support of decision-making process in production and economic systems both newly developed by the company (enterprise) and designed on the basis of available information systems that interact through the exchange of data. In addition, this article shows that the development of conceptual foundations of innovative project management in the economic and production systems is inseparable from the development of the theory of industrial control systems, and their comprehensive study may be reduced to a set of elements represented as certain algorithms, models and evaluations. Thus, the study of innovative process may be conducted in both directions: from general to particular, and vice versa.

Credit markets and the propagation of monetary policy shocks

This paper analyzes the propagation of monetary policy shocks through the creation of credit in an economy. Models of the monetary transmission mechanism typically feature responses which last for a few quarters contrary to what the empirical evidence suggests. To propagate the impact of monetary shocks over time, these models introduce adjustment costs by which agents find it optimal to change their decisions slowly. This paper presents another explanation that does not rely on any sort of adjustment costs or stickiness. In our economy, agents own assets and make occupational choices. Banks intermediate between agents demanding and supplying assets. Our interpretation is based on the way banks create credit and how the monetary authority affects the process of financial intermediation through its monetary policy. As the central bank lowers the interest rate by buying government bonds in exchange for reserves, high productive entrepreneurs are able to borrow more resources from low productivity agents. We show that this movement of capital among agents sets in motion a response of the economy that resembles an expansionary phase of the cycle.

Locations and Relocations:Modelling, Determinants, and Interrelations

Empirical studies on industrial location do not typically distinguish between new and relocated establishments. This paper addresses this shortcoming using data on the frequency of these events in municipalities of the same economic-administrative region. This enables us to test not only for differences in their determinants but also for interrelations between start-ups and relocations. Estimates from count regression models for cross-section and panel data show that, although partial effects differ, common patterns arise in “institutional” and “neoclassical” explanatory factors. Also, start-ups and relocations are positive but asymmetrically related. JEL classification: C25, R30, R10. Keywords: cities, count data models, industrial location
