The goal of this paper is to identify farmers’ future in terms of the pesticide management of potato growing farmers in Vereda la Hoya (Boyacá, Colombia).To achieve this goal we applied the Future-Structured Mental Model Approach (Future-SMMA) and interviewed 10 farmers concerning their future perspectives and expectations to derive their future visions. Subsequently, 10 experts were interviewed about the feasibility and the consequences of farmers’ future visions.Applying the Future-SMMA, we analyzed farmers’ future visions and found that farmers take account of social and environmental threats and that their visions are optimistic. In addition we compared farmers’ and experts’ perceptions of external constraints on farmers’ future and discovered that the future visions of farmers and experts were inconsistent. Finally, we determined how farmers’ livelihood assets and self-perception influence the formation of farmers’ future visions and found that the more a person was able to differentiate his livelihood assets the more differentiated were the future visions of that person.In discussing our findings, we deduce that the inconsistency of future visions found is due to diverging attitudes towards future scenarios and differing opinions about who should take responsibility for the knowledge management of farmers. 相似文献

Education and its intergenerational transmission: country of origin-specific evidence for natives and immigrants from Switzerland 总被引:1,自引:0,他引:1
This study compares the intergenerational transmission of educational attainment across immigrant groups using the Swiss Census 2000. Determinants of educational outcome and educational mobility are examined. A child’s educational opportunity depends on its parental background. Not only the effect of parental human capital but also other determinants of child educational attainment vary depending on the child’s nationality. Overall educational upward mobility is more pronounced among second generation immigrants than among natives. Children of Turkish, Portuguese and former Yugoslavian origin appear to be most disadvantaged in the process of human capital formation.

We employ the forward‐looking implied dividend information contained in option prices to predict dividend cuts and omissions during the recent financial crisis. The large number of dividend cuts and omissions during the 2008–09 financial crisis period provides the opportunity to study the predictability of dividend cuts in a controlled environment. Implied dividends and implied volatility, based on put–call parity and computed from put and call option prices, prove to be effective in predicting those cuts, especially compared to only using the equity market and accounting variables conventionally used for this purpose. Options‐derived variables (implied dividends and implied volatility) enhance the ability to identify firms more likely to reduce or omit dividend payments. 相似文献

In this study, the heterogeneity of the fee abolition process in West German secondary schools is used to identify the effect of school fees on educational attainment and to obtain an estimate of the price elasticity of upper secondary education. The analysis is based on representative individual‐level data from three annual surveys of the German Mikrozensus. While coefficients cannot be estimated precisely, the results suggest that, on average, upper secondary school attainment increased by at least 8 percent in response to the fee abolition. The educational attainment of females appears to be more price sensitive than that of males. 相似文献

Given industry competitiveness, how do firms' new product development (NPD) process designs differ when responding to an innovation mandate? How do NPD design elements differ across firms when implementing NPD processes? These design elements are strategic business unit (SBU) senior management involvement, business case content, customer interactions, and cross‐functional integration. What are the consequences of different combinations of NPD process design elements for innovation productivity? We explore these questions via a collective case study of newly implemented NPD process designs at three different SBUs of a major US‐based international conglomerate, 1 year after receiving the mandate to grow through innovation. Our analysis suggests that industry competitiveness and firm characteristics influence the NPD process design as SBUs employ distinct combinations of NPD design elements. The differential emphasis on design elements leads to variation in process design and divergence in innovation productivity. 相似文献

The Spanish peseta never formally belonged to the gold club, neither the classical nor the exchange-rate gold standards. It has been traditionally argued that the reason was the predominance of deficits in the Spanish budget from 1874 to 1935. The financing needs of the Treasury led to money creation and, consequently, to sacrificing the gold commitment and a fixed exchange rate. Applying a stationary VAR (Vector AutoRegressive) model, this paper estimates the dynamic link between budget and money and tests whether Spanish fiscal policy actually influenced monetary policy. The results confirm the dominance of fiscal policy for the period and, therefore, provide empirical support to the idea that the problems of the Treasury were behind Spain’s renouncement of gold. 相似文献

In this article we sought to develop a methodology for estimating the level and composition of potential trade between Israel and its Arab neighbors. The need for such a methodology derives from the fact that the existing trade of these countries with the rest of the world constitutes an insufficient basis for predicting bilateral trade patterns between them. Trade based on input sharing can be an important source of ''new trade'' that is, trade that is not necessarily related to goods and services currently traded by the countries in question. New trade based on input sharing pertains to the imports by Arab countries of inputs in which Israel has a proven comparative advantage, and to imports by Israel of inputs produced in Arab countries in which the latter have a proven comparative advantage. It stands to reason that branches characterized by comparative advantage in the exporting country can improve the competitive position of the import ing country, when incorporated in the latter's final products. The analysis confirms that in agricultural produce, food products, and certain sub-branches of the textiles and clothing industry, Jordan, Syria, and Egypt all appear to be potential suppliers to Israel. Inter alia, the results show that the Israeli import potential of inputs from Jordan appears to be both larger and more evenly distributed among the different branches than the import potential from Syria and even from Egypt. This finding does not accord with expectations in view of the fact that Jordan has a smaller population and a lower gross domestic product than either Egypt or Syria. Jordan stands out in that its construction industry, including ceramic products, nonmetallic minerals, and structural metals, are also potential suppliers. The methodology developed in this article specifically concerns potential trade between Israel and its Arab neighbors. It can be usefully employed in other situations where trade between pairs of countries is either nonexistent or severely distorted by political or other factors. Examples which come to mind include trade between countries which in the past belonged to the Soviet bloc, or trade between these countries and the rest of the world. In such cases it is improper to base one's trade predictions on the countries' existing trading patterns. New trade, which can be very substantial, and which may have a very different composition from current trade of the parties concerned, must be added to the equation. The methodology demonstrated in this article can be easily adapted for this purpose. 相似文献
