Strategies to increase agricultural productivity and reduce land degradation: evidence from Uganda 总被引:3,自引:0,他引:3

This paper estimates a structural econometric model of household decisions regarding income strategies, participation in programs and organisations, crop choices, land management, and labour use, and their implications for agricultural production and soil erosion; based upon a survey of over 450 households and their farm plots in Uganda. Many factors have context-specific impacts and involve trade-offs between increasing production and reducing land degradation. Government agricultural extension and training programs contribute to higher value of crop production in the lowlands, but to soil erosion in the highlands. By contrast, non-governmental organization (NGO) programs focusing on agriculture and environment help to reduce erosion, but have less favourable impacts on production in the lowlands. Education increases household incomes, but also reduces crop production in the lowlands. Poverty has mixed impacts on agricultural production, depending on the nature of poverty: smaller farms obtain higher crop production per hectare, while households with fewer livestock have lower crop production. Population pressure contributes to agricultural intensification, but also to erosion in the densely populated highlands. Several household income strategies contribute to increased value of crop production, without significant impacts on soil erosion. We find little evidence of impact of access to markets, roads and credit, land tenure or title on agricultural intensification and crop production and land degradation. In general, the results imply that the strategies to increase agricultural production and reduce land degradation must be location-specific, and that there are few 'win-win' opportunities to simultaneously increase production and reduce land degradation. 相似文献

abstract It is crucial from an employee's point of view to perceive some degree of stability even in times of major organizational change. This paper examines the role of a sense of continuity for organizational identification after an organizational merger. We argue that mergers and acquisitions so often end in failures partly because the change is designed in discontinuous ways and employees do not feel they are doing the same job after the merger as before. Such discontinuous change engenders a critical tension between positive and negative effects of identification that has not yet been fully understood. To deepen the understanding of this tension, in‐depth interviews were conducted in a recently merged German industrial company. Based on these qualitative data we demonstrate how features of the post‐merger company structure and the way it was implemented may have eroded organizational identification. Finally, we propose a parsimonious model to be tested by future research, in which the sense of continuity is consisting of both observable as well as projected continuity. 相似文献

Using store‐level panel data for a major supermarket company, we investigate the linkages between employee attitudes, customer satisfaction, and sales performance, while controlling for observed and unobserved differences across stores. We find that employee attitudes positively affect customer satisfaction with service but do not affect customer satisfaction with quality or value. Additionally, we find that customer satisfaction with service positively affects sales performance. Our results suggest that employee attitudes affect sales performance through their impact on customer service. Copyright © 2008 John Wiley & Sons, Ltd. 相似文献

This article analyzes factors that influence motivation of sales representatives. Findings of two research studies identify motivational characteristics of salesmen in sales agencies. The authors classify salesmen as High Actualizer, High Security, and High Love-Belonging types, based on their research findings. The research points out conditions which enhance sales performance and contribute to a highly motivated sales force. Specific guidelines are suggested to improve motivation of salesmen. 相似文献

This paper presents the results of a study of hotels that are certified for quality management to identify the reasons for seeking quality certification. The authors analyse whether internal or external drivers for seeking certification have different impacts on benefits and the use of quality tools in the hotel industry. The analysis groups hotels according to the importance of their internal reasons for certification, and uses cluster analysis to identify the significant differences between groups of hotels. The findings for the 32 hotels analysed show that hotels that pursued certification for internal reasons develop better quality tools and have increased levels of benefits. 相似文献

Employee voice to supervisors 总被引:3,自引:0,他引:3
David M. Saunders Blair H. Sheppard Virginia Knight Jonelle Roth 《Employee Responsibilities and Rights Journal》1992,5(3):241-259
This article reports the results of two studies examining some factors that increase the likelihood that employees will voice to their supervisors. The way employees perceive that their supervisors manage employee voice was identified as a major cause of the likelihood that employees will voice upward. The Supervisor as Voice Manager Scale is presented along with data demonstrating its reliability and validity. Theoretical and applied implications of the results are discussed.Faculty of Management, McGill University.Fuqua School of Business, Duke University.Mathematics & Computer Science, Meredith College.School of Management, Georgia Institute of Technology. 相似文献

A Bayesian regression procedure (RBAYES) is proposed for the optimal combination of self-explicated data (priors) and conjoint judgments. The procedure does not require the design matrix for the conjoint judgments to be of full rank. The Bayesian regression procedure is similar to weighted least square in that it uses an information ratio to weight the priors. We provide empirical comparisons for the proposed method against (1) a Stein-type estimator (SBAYES) using one data set and (2) OLS applied to the data from an adaptive conjoint analysis using a second data set. In the second application we also use an alternating least squares procedure by itself and in combination with Bayesian regression (RBAYES+) to accommodate scale incompatibility as well as heteroscedasticity. In both applications we obtain superior results for the Bayesian regression procedure. 相似文献

The objective of this paper is to examine hypotheses about the relationships between socio-economic factors, risk factors in working life, and the occurrence of mental illness, together with the degree of quality of life and consumption of health care, costs for health care, and costs for social insurance. This is a prospective and longitudinal study of 1,347 individuals of an active working age, 18–64 years, who have been on sick leave for more than 30 days. The group is characterized by the prevalence of risk factors in their work environment and welfare losses, such as multiple health problems, poor quality of life, inability to work, and dependency on society's support from health care and social insurance. The costs for health care were just over 2.8 million SEK, or 30 percent higher for those with psychological distress as compared to the group without. The payments from social insurance also increased by approximately 15 percent. The relatively greater weighting of health care costs and sickness cash benefits were motivating factors to study whether this group had an optimal amount and quality of health care, or if the resources available for health care should be distributed in another way that better satisfies the needs of the group. 相似文献

Debt as a collusive device in an oligopoly supergame 总被引:1,自引:0,他引:1
Dick Damania 《Journal of Economics》1997,66(3):249-269
This paper explores the impact of debt holdings on the output decisions of firms in an oligopoly supergame with stochastic demand fluctuations. It is demonstrated that when perfect collusion is not feasible then there exist circumstances in which increased debt holdings may facilitate tacit collusion. This occurs because higher debt levels act as a credible commitment device which lowers the payoffs accruing to a firm when it defects from the tacitly collusive equilibrium. It is further shown that in these circumstances firms may have an incentive to hold debt for strategic purposes which promote collusion. 相似文献
