In a recent paper published in the Economic Journal, Professor William D. Nordhaus of Yale University reviewed World Dynamics by Jay W. Forrester. In his criticism, Nordhaus signals three serious problems and several additional questionable assumptions of sufficient importance to undermine the usefulness of Forrester's book. However, a careful examination of his analysis shows that each point made by Nordhaus rests on a misunderstanding of World Dynamics, a misuse of empirical data, or an inability to analyze properly the dynamic behavior of the model by static equilibrium methods.The three serious problems raised by Nordhaus concern the assumptions that connect industrialization to net birth rates in World Dynamics, the representation of technology and production within the world model, and the impact of prices on global resource use. The analysis presented here refutes the Nordhaus arguments and shows that World Dynamics is consistent with his references to real-world data on population, production, and capital accumulation.This paper is a response to William D. Nordhaus, World Dynamics: Measurement Without Data, published in the Economic Journal, Royal Economic Society, December 1973. An earlier, unpublished, version of the Nordhaus paper, bearing the same title, was widely circulated hand-tohand within the United States, Canada, and Europe. A response to the original Nordhaus paper (System Dynamics Group Memorandum D-1736-4) was written in February 1973 and is available from Jay W. Forrester, Alfred P. Sloan School of Management, Massachusetts Institute of Technology, Cambridge, Mass. 02139. The present paper, a revised version of the earlier response, deals with several new or modified arguments contained in the Economic Journal article by Nordhaus. 相似文献

Does ink age inside of a pen cartridge? 总被引:2,自引:0,他引:2
In questioned document examination and ink dating, it has been assumed that the ink inside of a pen cartridge does not begin aging until the ink is dispensed onto paper. Positive ion laser desorption (LD) mass spectra were obtained of ink-on-paper samples containing methyl violet, from new and old pens. Mass spectral studies with methyl violet have established the mechanism for how the dye degrades over time, and have provided structural information concerning the dye's degradation products. This information was used as an indication of the relative age of ink on paper. The LD mass spectrum of the ink from a new pen was indicative of "new" ink, whereas the spectra of the ink found in some older pens may appear to be either new or old. The ink from most of the old pens studied appears not to have aged, supporting the common assumption, whereas other ink samples produced "aged" ink spectra, suggesting otherwise. 相似文献

This study investigates the alleged link between casino gambling and arrests for the commission of the “white collar” crimes
of forgery, fraud, and embezzlement. The rapid expansion of casino gaming venues in recent years has been said to have increased
the incidence of white collar crimes by casino customers who get themselves in financial trouble by overspending at casinos
(given the median age of 47 for casino patrons and that 41% hold white collar jobs). This study investigates this question
by using several kinds of data to examine arrest and offender trends, using a follow-up period of up to 10 years to assess
long-term impacts. The results indicate that, comparing pre- and post-casino average annual arrests for embezzlement, forgery,
and fraud, trends show a general decrease in arrests in casino jurisdictions, although embezzlement arrests rose in Connecticut
and in nationwide statistics. An assessment of the reasons offered from interviews with people convicted of embezzlement and
fraud are presented to examine the extent to which gambling is a causal factor.

Foster care is an integral component of the child welfare system. However, little is known about factors germane to conceptualizing successful foster care. This study utilized Concept Mapping (CM) to delineate a conceptual domain for what success in foster care means from the perspective of those most impacted: foster youth. CM couples multi-dimensional scaling with hierarchical cluster analyses to form factors relevant to an area of study. Pictorial representations of the data were generated using the Concept Systems software. Results indicate that youth conceptualize success based on several distinct domains. The final analyses yielded a multi-cluster solution, or Concept Map. 相似文献

Viewing Constance Maynard's unwieldy life-writings within the tradition of spiritual autobiography reveals many of the irresolvable tensions with which she wrestled. Although she chose to see her public role as spearheading a crusade against modern rationalism, her inner life was as much concerned with the struggle to repudiate her parents’ ascetic Evangelical piety in favour of a more emotionally intense spirituality. Her conviction of conversion's centrality fostered a sense of mission which bolstered a sense of her own exceptionality as a ‘prophet’ chosen by God. This in turn nourished her belief that she was justified in exempting herself from the roles and relationships conventionally assigned to her gender, by pursuing same-sex desire and sexless motherhood. 相似文献

This paper analyzes the different approaches for Internet regulation. We use the United States and European Union to illustrate
the alternative approaches of self-regulation and government intervention. Our research suggests that both systems have serious
shortcomings that could be ameliorated by the use of a mixed system for Internet regulation in which both the private and
public sector have a role. The case study of privacy rights self regulation in the United States and its failure to effectively
provide privacy regulation serves as our empirical evidence. We provide guidelines for both the government and the private
sector in defining and enforcing privacy regulation.
