Evaluation of the trench‐bed method of vegetable growing in semi‐arid areas

Layered fertility trenches when compared with conventional gardening methods showed little, if any, benefits in yield or water conservation on two soils over several planting seasons. While not conclusively discounting the fertility trench method, it brings into question the wisdom of introducing new methods that may not have clear advantages over traditional methods.     

Emerging markets, evolving institutions, and the new opportunities for growth in China's rural economy

In this essay, our goal is to assess the state of China's rural economy and examine whether rural China is capable of participating in the sequence of economic events that will lead to modernization. We examine how agricultural productivity has changed, the nature of the shift of labor moving from rural to urban areas, how commodity markets have evolved, and how the rural industrial sector is adjusting the recent reforms. According to our own work and that of others, we show how the rural economy is beginning to be fundamentally transformed and is contributing to China's modernization.     

MANAGING VENDOR INVENTORY IN A DUAL LEVEL DISTRIBUTION SYSTEM

Collaborative arrangements among members of the supply chain have received a great deal of interest in recent years as a means of reducing costs. One such arrangement is vendor managed inventory (VMI). VMI allows the vendor to make decisions concerning the quantity and timing of deliveries to the retailer. Such an arrangement offers the potential of a more efficient supply chain by removing the negative effects of retail ordering policies. A thorough review of the literature was conducted to identify factors likely to impact the performance of a VMI partnership. Computer simulation was used to study the effects of these factors from both the vendor's and retailer's perspectives. The results lend insight into the performance of VMI and guidance for managers as to the environments in which VMI is most effective.     

Management and the Professions: How Cracked is That Glass Ceiling?

All prestigious or highly-paid occupations in Britain are dominated by men: this is as true of the public sector as it is of industry. This article examines the evidence for discrimination in the public sector. It deals with both the situation at work and the one at home. It looks at various explanations as to why this is the case, as well as the evidence on how men and women deal with the inequality. The author concludes that there are good reasons why men and women do not see or confront the issues discussed in her article. Unless men and women wake up to the fact that we live in an unequal society and wish to see the glass ceiling well and truly broken, little is likely to change.     

The impact of skewness in the hedging decision

The impact of skewness in the hedger's objective function is tested using a model of hedging derived from a third‐order Taylor Series approximation of expected utility. To determine the effect of price skewness upon hedging and speculation, analytical results are derived using an example of cotton storage. Findings suggest that when forward risk premiums and price skewness in the spot asset have opposite signs, speculation increases relative to the mean‐variance model. When the signs are identical, speculation will decrease, contradicting findings of mean‐variance models. © 2006 Wiley Periodicals, Inc. Jrl Fut Mark 26:503–520, 2006     

Effects of demographic,experiential, and attitudinal factors on occupational sex stereotypes

The purpose of this study was to (a) compare the occupational sex stereotypes of 366 college students with those reported by Shinar in 1975, and (b) examine the relationships between demographic, experiential, and attitudinal variables and these occupational sex stereotypes. The results indicated a significant difference in occupational ratings from Shinar's study, with females' perceptions shifting more than males' perceptions. In addition, subjects' gender, tenure with female managers, and attitudes toward women as managers, were shown to be significant predictors of occuptational ratings. The implications of these findings for both employees and managers are then discussed.     

Electronic data interchange: a strategic approach

The potential of EDI is virtually unlimited, but the success of any EDI initiative hinges on its ability to directly support strategies that achieve your institution's business objectives. At its most fundamental level, EDI technology automates current business practices, speeding up the exchange of business information. This application of EDI most often is found in a hospital's material management department. But EDI integrated internally within a hospital and externally with suppliers and vendors has the potential to go beyond simple automation and to transform processes. This is where the full value of EDI can be realized. No matter which level of EDI participation hospital management decides is appropriate to fulfill its business objectives and strategies, EDI will affect the entire institution's exchange of information with its internal and external audiences. The question management must answer is: Will the hospital's EDI strategy be offensive and managed, or defensive and reactive? Today's environment leaves no room for a "no-strategy" EDI option. The options are either to proactively shape EDI, or reactively play catch-up. EDI can work for you. Adequately developing an EDI game plan in support of your business objectives and calling on your suppliers and other trading partners to work with you will ensure EDI is an asset to your facility.     

Contrast enhancement of the gastrointestinal tract on MR images using intravenous gadolinium-DTPA

Gadopentetate dimeglumine was administered intravenously to 16 patients undergoing abdominal magnetic resonance (MR) imaging. T1-weighted and fat-suppressed T1-weighted images were acquired before and after intravenous administration of 0.1 mmol/kg gadopentetate dimeglumine. The stomach, small bowel, and colon were analyzed regarding the presence and relative intensity of contrast enhancement. Diffuse enhancement of the gastrointestinal tract wall was observed in all patients following contrast material administration. Such enhancement was most conspicuous on fat-suppressed T1-weighted images. Quantitative measurements indicated that the wall of the gastrointestinal tract enhanced approximately 100% with gadopentetate dimeglumine. This study demonstrates that enhancement of the normal gastrointestinal tract occurs routinely when intravenous gadopentetate dimeglumine is administered, and such enhancement should not be considered indicative of gastrointestinal pathology. Furthermore, it suggests the potential utility for using intravenous rather than orally administered contrast agents to provide enhancement of the gastrointestinal tract on MR images.     

Developing holistic leaders: Four domains for leadership development and practice

Leadership development and practice have traditionally been quite narrow, with a decided focus on the analytical realm of leadership. However, the contemporary climate of corporate scandal and resultant loss of societal confidence, coupled with the evolving demands, needs, and expectations of employees, point to the potential need for a more holistic approach to leadership. Thus, this article proposes how management education and leadership development programs can develop holistic leaders that are adept at operating in the analytical, conceptual, emotional, and spiritual domains of leadership practice. An integrated model for holistic leadership development and practice that addresses all four of these domains is proposed, and grounded in both established and emerging leadership development theory. Additionally, a leadership development classification scheme is proposed based on classroom, job, and organizational contexts.     

中国农村社区公共物品投资的决定因素分析

本文使用具有全国代表性的抽样调查数据,对农村社区公共物品投资的决定因素进行了初步的分析。本文通过理论分析提出了两个理论假说,进而提出在我国公共投资中要注意的问题:既要考虑各地对公共投资有不同的需求,还要考虑区域协调发展。研究结果表明,除了一些政策因素以外,当地经济发展水平是影响农村公共投资的重要因素,一般来说,在工商业较发达的村公共投资活动也相对较多。对于外出务工人员较多的村,由于本地公共投资对外出务工人员的收入等作用较小,因此这部分村民就不那么愿意对村里进行公共投资。从政策实施角度看,本研究发现,上级政府的公共投资更多地投向贫困地区、偏远山区、农业生产条件差的地区或少数民族地区。这种投资战略有助于统筹区域发展,降低区域差异。
