Soil fertility decline and soil management for crop production are important economic issues for grain growers in north-eastern Australia. In that region, there is evidence of soil fertility decline which is attributed to past crop management practices. The questions addressed in this article are first, whether components of soil fertility can be improved by better management and second, by how much soil fertility would change. Soil fertility for crop production is considered in terms of soil organic carbon and nitrogen. A stochastic dynamic economic analysis of soil fertility management for wheat production is presented. A sequential analysis of first deriving the optimal nitrogen stock and application rates is followed by an assessment of tillage, stubble, and fertilizer strategies to obtain an optimal level of soil organic carbon. The recommended management practices are consistent with emerging management trends in the region. The derivation of optimal levels of soil fertility for agricultural purposes has other policy implications, which we discuss. 相似文献
Suffering comes in many forms that significantly impact organizations’ operations and performance. As a result, recent research on compassion organizing seeks to explain how efforts to notice, feel, and respond to suffering create organizational (and societal) benefits. Widespread suffering can be generated by natural disasters, which in turn can trigger compassionate organizational responses. In this paper, we build on social capital theory to theorize about how compassionate ventures leverage network relationships to identify and mobilize resources. We also explore how differences in these approaches influence the magnitude, speed, and customization of the response, all of which are theorized indicators of the effectiveness of compassion organizing in alleviating suffering. We use structural equation modelling to test our model and find that compassionate ventures with stronger ties to the local community are more likely to bundle (i.e., stretch) resources, which facilitates a speedy, customized, and large magnitude response. In contrast, those with stronger ties outside the local community are more likely to pursue (i.e., chase) new resources, which results in a large magnitude response, but one that is not associated with speed or customization. We discuss the implications of our findings and make recommendations for future research. 相似文献
In this paper, we assess the determinants of secondary school outcomes in South Africa. We use Bayesian model averaging techniques to account for uncertainty in the set of underlying factors that are chosen among a very large pool of explanatory variables in order to identify the subset of explanatory variables most strongly associated with the dependent variable. Our analysis indicates that the socio‐economic background of pupils, demographic characteristics such as population groups (Black and White), as well as geographical locations account for a significant variation in pupils’ achievement levels. We also find that the most robust policy determinants of pupils’ test scores are the availability of a library at school, the use of IT in the classroom as well as school climate. 相似文献
We use the US International Trade Commission's uniquely detailed 1995–2007 Chinese Customs data to better understand the pattern of trade between China and its two largest trading partners, Japan and the United States. Our review finds that only a small share of these flows can be characterized as arm's length, one-way trade in final goods. Instead, we find extensive two-way trade, deep vertical specialization, concentration of trade in computer and communication devices, and a prominent role for foreign-invested enterprises. While these characteristics define both bilateral relationships, important differences between the two pairs do emerge, suggesting that trade costs influence the method by which multinationals choose to integrate their production with China. Consequently, we argue that dialogue on East Asian trade liberalization should include the possibility of significant production gains for the US from its inclusion in any regional agreements. 相似文献
Containerized freight imports into the US are growing at an average of 10% per year. This traffic is concentrated at a small number of US seaports. It is therefore important to have an accurate understanding of the flow of containers from their origin country through these seaports to their final destination. This paper develops an optimization model to estimate route flows and a corresponding multi-modal origin–destination table for containers by synthesizing data on international trade and railcar movements with a gravity model for the demand of container traffic. This analysis provides insights into the balance of rail and truck inland transportation from each port. 相似文献
The paper lays the foundation for building a dynamic theory of the impact of process innovation upon competitive strategies. An innovation is tracked over two and a half decades to observe changing patterns in competition resulting from ongoing innovation development, emerging complementary technologies, and expanding use. The study finds that the innovation created competitive opportunities and threats for both firms that adopted it and those that did not. 相似文献

This study examines the effects of adaptive/innovative cognitive style, and professional development on the initiation of radical and non‐radical innovations by individual management accountants. Data are gathered through questionnaire and follow‐up interviews with practising management accountants. The results show that management accountants with a more innovative (adaptive) cognitive style tend to initiate more (fewer) radical relative to non‐radical innovations, and that this effect is amplified by professional development. The study has implications for research in management accounting innovation and for practice, including the importance of maintaining a balance of radical and non‐radical innovations in organizations, and of professional development. 相似文献
