Germinación como parámetro de selección en Karwinskia por su potencial de productividad en peroxisomicina A1
Provedor de dados: 85
Autores: Luján-Rangel,R; Olivares-Sáenz,E; Vázquez-Alvarado,RE; Garza-Ocañas,L; Torres-Alanís,O.
Karwinskia parvifolia (Kp) y Karwinskia humboldtiana (Kh) son plantas venenosas de la familia rhamnácea. Los estudios toxicológicos y clínicos realizados con uno de los compuestos presentes en el fruto [peroxisomicina A1 (PA1)) sugieren su posible utilidad farmacológica en el tratamiento de algunos tipos de cáncer. Esta es la razón por la cual estas plantas se cultivan para incrementar su productividad en PA1. Se investigó el efecto del nitrógeno y de la especie sobre la viabilidad de las semillas, y se determinó la curva de germinación para Kp con (grupo Kp-CN) y sin (grupo Kp-SN) nitrógeno, y para Kh sin nitrógeno (grupo Kh-SN) a través del modelo probit. Este modelo se caracteriza por la probabilidad de germinación en función del tiempo. Los resultados...

The Right Amount of Trust
Provedor de dados: 31
Autores: Butler,   Jeffrey; Giuliano,   Paola; Guiso,   Luigi.
We investigate the relationship between individual trust and individual economic performance. We find that individual income is hump-shaped in a measure of intensity of trust beliefs. Heterogeneity of trust beliefs in the population, coupled with the tendency of individuals to extrapolate beliefs about others from their own levels of trustworthiness, could generate this non-monotonic relationship: highly trustworthy individuals tend to form overly optimistic beliefs, to assume too much social risk and to be cheated more often, ultimately performing less well than those with a belief close to the mean trustworthiness of the population. On the other hand, less trustworthy individuals form overly pessimistic beliefs and avoid being cheated, but give up...

THE ECONOMICS OF POVERTY AND THE POVERTY OF ECONOMICS:  A CHRISTIAN PERSPECTIVE
Provedor de dados: 31
Autores: Barrett,   Christopher B.
In this world of plenty, almost half of the world's six billion people live on two dollars a day or less and the number living on less than one dollar a day has increased over the past fifteen years (World Bank 2000). Between one third and one half suffer under nutrition due to insufficient intake of calories, protein or critical micronutrients such as vitamin A, iodine and iron. More than one child in five lives in acute poverty. Why does such unnecessary injustice continue to disfigure a rich, technologically advanced world and what can be done to care for the poor and thereby to care for and honor God, as the Gospels instruct us?  In attempting to answer those questions, at least partly, this paper offers some insights from recent research in economics,...

The Controversy of Exchange Rate Devaluation in Sudan: An Economy-wide General Equilibrium Assessment
Provedor de dados: 31
Autores: Siddig,   Khalid H.A.
The international Monitory Fund (IMF) has been working with Sudan since 1997 to implement macroeconomic reforms including a managed float of the exchange rate (EXR). The IMF sees the EXR flexibility as key to safeguard and rebuild foreign exchange reserves and essential to meet the international reserve target in Sudan. However, the authorities in Sudan are concerned that greater exchange rate flexibility could contribute to inflationary pressures. In addition, a review of literature focusing on the exchange rate policies in Sudan reflects huge ambiguity about its outcome.  This calls for additional empirical investigations that provide economy wide assessments of the various possible scenarios that could be adopted in the Sudanese context. Accordingly,...

Long Term Structural Changes in the EU Countries (1970-2000): Convergence or Divergence in the Agri-Food System?
Provedor de dados: 31
Autores: Peroni,   Marco; Brasili,   Cristina; Fanfani,   Roberto.
The main objective of this paper is to analyse the structural changes in European Agri-food systems in the last 30 years in order to verify the presence of a convergence process towards a more homogeneous structure among EU countries. This analysis considers the relative importance of the main components of Agri-food systems (agriculture, food industry and food consumption) and how they change over time. The analysis of convergence utilise the European National Accounting Data (from the SEC2 Data Base of Eurostat) from 1970 to 2000 for twelve EU countries. We use tests of convergence on cross section data by countries, but also stochastic kernel methodologies to verify the dynamic evolution of groups of countries inside the EU. The results show there are...

A mosaic type of development - the Agri-food Districts experience in Italy
Provedor de dados: 31
Autores: Brasili,   Cristina; Fanfani,   Roberto.
The Italian Industrial Districts (IDs) are now considered in the national and international literature as one of the main factors of the successful and rapid industrial development of Italy after the Second World War. In this paper we outline the general characteristics of the IDs approach and then the distinctive figures of the agrifood districts. A mosaic type of development characterised the geographical distribution of the different agrifood districts in the Italian experience. The different origins of agrifood districts often determines their production and structural characteristics of firms, with a relevant role of SMEs. In many cases, these districts originated from handcraft traditions and specific local demand. Their specialized production is...

The Agrifood Districts in the New Millennium
Provedor de dados: 31
Autores: Brasili,   Cristina; Fanfani,   Roberto.
The Italian Industrial Districts (IDs) are considered to be one of the main reasons for the rapid industrial development and success of Italy since the Second World War. The SME's have also played an important role in this. In this paper we outline the general characteristics of the ID approach and the main structural changes in the new millennium, due to them facing the process of globalization. The distinctive figures of the agrifood districts and their mosaic style of development are than analysed to highlight the similarities and differences between them and the other IDs. First show that they are more relevant and that their geographical distribution is more important than those of other recently analysed Italian ID's. The different zones of origin of...
