Disciplines of Organizational Learning: Contributions and Critiques

The paper argues against attempts to create asingle framework for understanding organizationallearning. Relevant literature is reviewed from sixdisciplinary perspectives: psychology and OD; management science; sociology and organizational theory;strategy; production management; and culturalanthropology. It is argued that each discipline providesdistinct contributions and conceptions of problems.Furthermore, a basic distinction between organizationallearning and the new idea of the learning organizationis noted. Whereas the former is discipline based andanalytic,the latter is multidisciplinary and emphasizes action and the creation of anideal-type of organization. Due to thediversity of purpose and perspective, it is suggestedthat it is better to consider organizational learning asa multidisciplinary field containing complementary contributions andresearch agendas.     

Long-term impact of Drug Abuse Resistance Education (D.A.R.E.). Results of a 6-year follow-up

The long-term effectiveness of Drug Abuse Resistance Education (D.A.R.E.) was assessed by contrasting drug use and other D.A.R.E.-related attitudinal latent variables among 356 twelfth-grade students who had received the program in the 6th grade with 264 others who did not receive it. A prior study of these subjects when they were in 9th grade had shown no significant differences. A follow-up survey in 12th grade assessed central D.A.R.E. concepts such as self-esteem, police bonds, delay of experimentation with drugs, and various forms of drug use. Although the authors found no relationship between prior D.A.R.E. participation and later alcohol use, cigarette smoking, or marijuana use in 12th grade, there was a significant relationship between earlier D.A.R.E. participation and less use of illegal, more deviant drugs (e.g., inhalants, cocaine, LSD) in a development sample but not in a validation sample. Findings from the two studies suggest a possible sleeper effect for D.A.R.E. in reference to the use of harder drugs, especially among teenage males.     

Why China failed to create an endogenous industrial capitalism

Conclusion Weber almost anticipated the idea of the high-level equilibrium trap. Speaking about bureaucracy, he observed that as always in the area of'techniques' ... advance proceeded most slowly wherever older structural forms were in their own way technically highly developed and functionally particularly well-developed to the requirements at hand. It is a pity that he did not utilize this insight to analyze what he called the increasing stability of the economic situation under conditions of the economically self-sufficient and socially homogenously composed world-empire of China. Instead he pursued the idea that the absence of self-generated capitalism in China was due basically to the lack of a particular mentality. This inappropriate mentality had several aspects. One was the personalist principle. Others are listed in a catalog of alleged traits of personality taken largely from Arthur Smith's Chinese Characteristics. They include stolidity, patience, dislike of novelty, absence of curiosity, credulity, and a general distrust of and dishonesty towards all. Having acknowledged China's considerable technical endowments and inventions (Weber's own quotation marks), he argued that the magic stereotyping of technology and economics... completely precluded the advent of indigenous modern enterprises in communication and industry. The Chinese world, in a famous phrase, was a magic garden in which the ethical rationality of the miracle [was] out of the question. Certain points of detail may be disputed. Thus the miracles attributed to the piety of sons and the fidelity of widows were entirely ethically rational. But the crucial fact is that this conception of the problem led Weber in practice to place an excessive faith in the explanatory power of an analysis of ideas considered in relative isolation from their socioeconomic context. It probably also weakened his sense of the need to sort out more systematically the somewhat internally contradictory opinions that he held on the more specifically economic aspects of Chinese society.

The transition to marriage

Cohabitation has often been viewed as easing the transition to marriage. The question is therefore asked, what characterizes relationships in which couples live together for an extended period of time prior to marriage, then decide to marry, and within two to three years are divorced? Four groups were interviewed (cohabitated/married; cohabitated/married/divorced; dated/married; dated/married/divorced) with the hope of analyzing the differences or similarities in the marital transitions made by individuals within these groups. The total sample consisted of 40 respondents who were given an in-depth, face-to-face interview. It was found that the degree of congruence between dyad members regarding perceptions and expectations surrounding marriage and marital life was an important factor in the success with which couples were able to make the marital transition.     

Dose‐Response Models Incorporating Aerosol Size Dependency for Francisella tularensis

The effect of bioaerosol size was incorporated into predictive dose‐response models for the effects of inhaled aerosols of Francisella tularensis (the causative agent of tularemia) on rhesus monkeys and guinea pigs with bioaerosol diameters ranging between 1.0 and 24 μm. Aerosol‐size‐dependent models were formulated as modification of the exponential and β‐Poisson dose‐response models and model parameters were estimated using maximum likelihood methods and multiple data sets of quantal dose‐response data for which aerosol sizes of inhaled doses were known. Analysis of F. tularensis dose‐response data was best fit by an exponential dose‐response model with a power function including the particle diameter size substituting for the rate parameter k scaling the applied dose. There were differences in the pathogen's aerosol‐size‐dependence equation and models that better represent the observed dose‐response results than the estimate derived from applying the model developed by the International Commission on Radiological Protection (ICRP, 1994) that relies on differential regional lung deposition for human particle exposure.     

A Comparative Pharmacokinetic Estimate of Mercury in U.S. Infants Following Yearly Exposures to Inactivated Influenza Vaccines Containing Thimerosal

The use of thimerosal preservative in childhood vaccines has been largely eliminated over the past decade in the United States because vaccines have been reformulated in single‐dose vials that do not require preservative. An exception is the inactivated influenza vaccines, which are formulated in both multidose vials requiring preservative and preservative‐free single‐dose vials. As part of an ongoing evaluation by USFDA of the safety of biologics throughout their lifecycle, the infant body burden of mercury following scheduled exposures to thimerosal preservative in inactivated influenza vaccines in the United States was estimated and compared to the infant body burden of mercury following daily exposures to dietary methylmercury at the reference dose established by the USEPA. Body burdens were estimated using kinetic parameters derived from experiments conducted in infant monkeys that were exposed episodically to thimerosal or MeHg at identical doses. We found that the body burden of mercury (AUC) in infants (including low birth weight) over the first 4.5 years of life following yearly exposures to thimerosal was two orders of magnitude lower than that estimated for exposures to the lowest regulatory threshold for MeHg over the same time period. In addition, peak body burdens of mercury following episodic exposures to thimerosal in this worst‐case analysis did not exceed the corresponding safe body burden of mercury from methylmercury at any time, even for low‐birth‐weight infants. Our pharmacokinetic analysis supports the acknowledged safety of thimerosal when used as a preservative at current levels in certain multidose infant vaccines in the United States.
