有机铬生产可行性分析 铬(Cr)是一种重要的营养成分。铬的主要生理作用是通过强化胰岛素功能而影响碳水化合物、脂类机蛋白质的代谢。在我国的食量结构中,由于精制、加工和土壤被淋洗,铬的摄取量很少。因此,不论是人类还是动物一般都缺铬。这种效果可以从补铬后动物生产能力的有利反应看出,畜牧生产所用的日粮中含铬量都不够,铬的补给应该提到日程上来。

An analysis of the profiles and motivations of habitual commodity speculators

The focus of this study is the habitual speculator in commodity futures markets. The speculator's activity broadens a market, creates essential liquidity, and performs an irreplaceable pricing function. Working knowledge of the profiles and motivations of habitual speculators is essential to both market theorists and policy makers. Responses to a 73-question survey were collected directly from retail commodity brokers with offices in Alabama. Each questionnaire recorded information on an individual commodity client who had traded for an extended period of time. The typical trader studied is a married, white male, age 52. He is affluent and well educated. He is a self-employed business owner who can recover from financial setbacks. He is a politically right-wing conservative involved in the political process. He assumes a good deal of risk in most phases of his life. He is both an aggressive investor and an active gambler. This trader does not consider preservation of his commodity capital to be a very high trading priority. As a result, he rarely uses stop loss orders. He wins more frequently than he loses (over 51% of the time) but is an overall net loser in dollar terms. In spite of recurring trading losses, he has never made any substantial change in his basic trading style. To this trader, whether he won or lost on a particular trade is more important than the size of the win or loss. Thus he consistently cuts his profits short while letting his losses run. He also worries more about missing a move in the market by being on the sidelines than about losing by being on the wrong side of a market move; that is, being in the action is more important than the financial consequences. Participating brokers confirmed that for the majority of the speculators studied, the primary motivation for continuous trading is the recreational utility derived largely from having a market position. © 1998 John Wiley & Sons, Inc.

Participation in the organization: An ethical analysis from the papal social tradition

How one structures an organization is not only important from the perspective of productivity and efficiency, but primarily how it affects the moral formation of those who are employed in that organization. Organizational structures whether in the manufacturing, service or non-profit sector have moral dimensions that cannot be escaped. Papal social tradition has been concerned about the moral formation of all workers within the organization. This tradition has maintained that an essential component to a humane organizational structure is participation of those involved in the organization, and consequently that participation must be understood primarily in terms of the formation of employees. This article explores the papal social tradition's understanding of participation and examines its significance in today's organizational environment, particularly in reference to work-teams.Michael Naughton is an assistant professor at the University of St. Thomas in St. Paul, MN. He holds a joint appointment in the theology and management departments. He received his Ph.D. in theology, where he studied social ethics and organizational theory.

He is the author ofThe Good Stewards which examines the relationship between organizational issues and the Catholic social tradition.

The Unholy Alliance of Business and Science

This paper will build on a recent article appearing in the Harvard Business Review that blamed the alleged crisis in management education on the scientific model that has been adopted as the sole means of gaining knowledge about human behavior and organizations. The solution, they argue, is for business schools to realize that business management is not a scientific discipline but a profession, and deal with the things a professional education requires. We will expand on this article and discuss its implications by looking at the scientific model from a philosophical perspective and dealing with the issue of whether management is a profession. Our discussion of these issues has implications for our understanding of business in society and the design of the business school curriculum. Rogene A.

Ethical Exemplification and the AICPA Code of Professional Conduct: An Empirical Investigation of Auditor and Public Perceptions

This research applies the impression management theory of exemplification in an accounting study by identifying and measuring differences in both auditor and public perceptions of exemplary behaviors. The auditors were divided into two groups, one of which reported self-perceptions (A-S) while the other group reported their perceptions of a typical auditor (A-O). There were two separate public groups, which gave their perceptions of a typical auditor and were divided based on their levels of accounting sophistication. The more sophisticated public group was comprised of bank loan officers (LO) while the less sophisticated public group consisted of investment club members (IC). Comparisons were made on 30 behaviors contained in the AICPA Code of Professional Conduct, which served as the basis for the research instrument. Profile analysis, a special form of MANOVA technique, was used to analyze the results. A-S perceptions were the highest of the four treatment levels and were significantly higher (i.e., more exemplary) than the perceptions of both the A-O and LO groups. The more sophisticated user group (LO) provided the lowest perceptions of the four treatment levels. For at least four of the six measures, the LO treatment group perceived the typical auditor to be less exemplary than both the IC and A-O treatments. There were no differences in perceptions between the A-O group and IC. Additional analysis revealed that auditors overrated the degree to which the public relied on financial statements. However, both public groups reported a reasonably high level of reliance on financial statements when making decisions. Philip A.
