Tef is the most important crop in Ethiopia and is well-adapted to growing environments, but grain yields are low. The government is therefore promoting the adoption of improved varieties, inorganic fertilizers and new planting techniques. This study gathered information on the use of new agronomic practices and barriers to their adoption through a semi-structured questionnaire administered to 60 farmers or respondents from each of 4 districts of Tigray region in northern Ethiopia viz Laelay-Maichew, Medebay-Zana, Ahferom and Alamata. Data were coded and analysed using SPSS software. Except for animal feed and crop rotation, there were significant differences between districts in the relative importance of several criteria for different uses. Improved varieties were used by the majority of respondents in all districts and fertilizers in all except Alamata where severe moisture stress dictated the choice of variety and reduced fertilizer application. Weed control was mainly by hand except in Alamata where chemical control was common because of the predominance of broad-leaved weeds. Transplanting maximized the yield of tef, but a cost–benefit analysis showed that row sowing was more profitable. The study concluded that new varieties better adapted to the likelihood of reduced rainfall and that respond efficiently to fertilizer inputs need to be developed. Until suitable technologies are available, high labour costs would in part dictate some agronomic practices, even if this led to lower yields. 相似文献

Two hundred ninety-three university business students were surveyed using an academic entitlement (AE) scale updated to include new technologies. Using factor analysis, three components of AE were identified: grade entitlement, behavioral entitlement, and service entitlement. A k-means clustering procedure was then applied to identify four groups based on the relative strength of the AE components: the model student, under the radar, instructor as servant, and the privileged. These groups were further characterized by additional demographic (i.e., parental income) and classroom variables (i.e., instructor response times). Findings can help business educators gain better insight into the AE construct and devise more effective instructional strategies. 相似文献

In a recent paper, Giugale and Korobow (2000) present evidence that suggests that the time required by output to return to trend following a financial shock is faster under a flexible exchange rate regime than under a fixed exchange rate. In this paper, we use vector autoregression models to measure the persistence properties of output for a number of countries in the Asia–Pacific region. Our results suggest that output persistence is not uniquely related to a country's choice of exchange rate regime. The two countries in our sample with the least persistent output following a financial shock are Australia, where the exchange rate is fully flexible, and Hong Kong, where it is rigidly fixed via a currency board. 相似文献

This study investigates the relevance and importance of firm size as a current research variable in international marketing while being cognizant of the reasons behind previous researcher's focus on firm size. Utilizing two different databases and analyses, this study integrates existing research on the effects of firm size variables on decisions in international marketing and draws a general conclusion. The main research questions center on whether firm size matters in internationalization decisions and whether firm size is a meaningful proxy for specific firm resources. Our results suggest that the effect of size on internationalization becomes less significant over time and that the effect of firm size on choice of ownership is significantly less than that of other firm-specific variables such as R&D intensity and advertising intensity, suggesting that strategic international marketing decisions are more related to a firm's unique assets than to its size. 相似文献

ABSTRACTThis article investigates how a firm's financial strength affects its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German firms in high-tech manufacturing industries. The model incorporates a measure of the firm's financial strength, derived from its credit rating, which is shown to lead to substantial differences in estimates of the costs and expected long-run benefits from R&D investment. Financially strong firms have a higher probability of generating innovations from their R&D investment, and the innovations have a larger impact on productivity and profits. Averaging across all firms, the long-run benefit of investing in R&D equals 6.6% of firm value. It ranges from 11.6% for firms in a strong financial position to 2.3% for firms in a weaker financial position. 相似文献

Brand communities are a commonly used marketing instrument to enhance customer attraction and retention. Well-known success stories of brand communities include brands such as Jeep®, Apple Macintosh®, or Harley Davidson®. Despite the great importance for companies to effectively manage the social facet of their products, research in this field has been rare. In literature, indications for success factors and constituting elements of communities have been found. However, seldom have viable business cases for the community operator been provided. We propose the mobile channel to be a particularly promising media for establishing brand communities. Due to the significant and still increasing worldwide penetration of mobile devices and current always-on location sensitive mobile services, innovative community concepts bear the potential for substantial value creation, which tends to result in positive effects on customer loyalty and brand equity for the community operator. In this article, we review selected literature to develop propositions on how concepts for mobile brand communities can be developed. Building on the 4 constituting elements of a community, which are member entities, shared interest, common space of interaction, and relation, combined with the specific characteristics of the mobile channel, which are location awareness, ubiquity, identification, and immediacy, we developed a procedure on how to design mobile brand communities according to perceived consumer value. We use the case of a mobile content provider to illustrate the suggested process. Starting from the theoretical mobile community model, we apply means–end chains to do justice to the specific brand values. In concluding, we propose a 4-step model of key mobile brand community design tasks. 相似文献

This paper identifies factors associated with takeoff—a sustained period of high growth following a period of stagnation. Countries that experience takeoffs average 2.3% annual growth following their stagnation episodes, while those that do not average 0%. Using probit, we find that de jure trade openness is positively and significantly associated with takeoffs. A one‐standard‐deviation increase in de jure trade openness is associated with a 55% increase in the probability of a takeoff in our default specification. Capital account openness encourages takeoff responses, but measures of de facto trade openness are found to be poor predictors of takeoffs. We also examine the determinants of nations achieving “sustained” takeoffs; i.e. those lasting eight years or longer. Takeoffs in countries with more commodity‐intensive output bundles are less likely to be sustained, suggesting that adverse terms‐of‐trade shocks may play a role in ending long‐term high growth episodes. 相似文献

The results of an econometric exercise are presented, showing that Monetary Policy Committee (MPC) members appointed from outside the ranks of Bank of England staff (outsiders) react differently to forecasts of inflation and output than those appointed from within the Bank (insiders). All results are reinforced by the well‐established findings that, compared with outsiders, insiders choose higher interest rates, are more likely to vote as a bloc, and feature on the winning side of policy decisions more frequently. On the basis of these results, it is argued that the current MPC framework is biased toward the policy choices of insiders. 相似文献
