We investigate how sociological argumentation differs from classical first–order logic. We focus on theories about age dependence of organizational mortality. The overall pattern of argument does not comply with the classical monotonicity principle: Adding premises overturns conclusions in an argument. The cause of nonmonotonicity is the need to derive conclusions from partial knowledge. We identify metaprinciples that appear to guide the observed sociological argumentation patterns, and we formalize a semantics to represent them. This semantics yields a new kind of logical consequence relation. We demonstrate that this new logic can reproduce the results of informal sociological theorizing and lead to new insights. It allows us to unify existing theory fragments, and it paves the way toward a complete classical theory. 相似文献

Developing a fair and widely accepted income definition presents one of the greatest challenges to tax reform. To arrive at a definition separate from the federal tax code, we surveyed 1200 Latter‐day Saints about their practice of tithing. Tithing is similar to a flat tax with no deductions, where individuals voluntarily contribute 10% of self‐defined income to the church. The results of our survey indicate that most respondents operate on a cash realization basis, which excludes savings and does not allow any deductions. Respondents' income concepts generally do not coincide with current tax laws or economists' views of comprehensive income. 相似文献

There was a time in this fair land when the railroad did not run When the wild majestic mountains stood alone against the
sun Long before the white man and long before the wheel When the green dark forest was too silent to be real
For they looked into the future and what did they see They saw an iron road running from the sea to the sea Bringing the goods
to a young growing land All up through the seaports and into their hands
From “Canadian Railroad Trilogy” by Gordon Lightfoot

his facilitating our initial access to the company. 相似文献

Many observers have noted that immigrants to the United States are highly concentrated in the largest metropolitan areas of a relatively few states. Though immigrants diffused into many places that had previously seen relatively few immigrants during the 1990s, as of the 2000 census, 77 percent of the nation's 31.1 million foreign born residents still lived in six states — California, New York, Texas, Florida, New Jersey, and Illinois. According to the 2000 census, the two largest metropolitan areas, Los Angeles and New York, accounted for one third of all immigrants ( http://www.census.gov/Press‐Release/www/2002/demoprofiles.html ). While immigrants moved into many new areas during the 1990s, making the challenge of incorporating their children a national issue, their concentration in our largest cities remained pronounced. 相似文献

There is a gulf between the analytic and experiential aspects of cross-culturalists' functioning that is reflected in the split between explicit scientific rules for studying the culture of others, while following an informal oral tradition for considering our own cultural makeup. This article discusses both a possible strategy for correcting this situation and the barriers that are likely to prevent such a correction. Structured cultural self-study procedures are presented as a possible resource in the continuing development of graduate students and professionals, and these have already proven highly effective in teaching cross-cultural psychology to undergraduates. Fostering commitments to standardized self-study and to applications of experiential learning is currently not likely to flourish due to complex academic and epistemic traditions, discussed as six cultural self-masking factors. A specific self-study protocol is offered to provide a beginning point for generating improved reflexive methods and for individual trial use. Through disciplined reflexivity, benefits might emerge in the form of better bias control in research, enhanced external validity, and a new theory about the interplay of investigators' self-knowledge and the conduct of cross-cultural research. 相似文献

We analyze the wealth ejfects of the Texaco racial discrimination lawsuit both on the shareholders of Texaco and its major
U.S. competitors. Employing a comprehensive data set which included every case docket entry and every Wall Street Journal
article on the case as an experimental stimulus, our findings suggest that the overall cost of the case to Texaco shareholders
exceeded $500 million, that Texaco's tribulations had little, if any, impact on the share prices of its major competitors,
and that Wall Street Journal coverage of the case was highly correlated with significant changes in Texaco stock prices. This
last finding provides significant support for Hite 's suppostion that newspaper editors “key ” on ex post stock price changes
in selecting the events to be covered in the next day's edition.

The development and initial psychometric properties of an adolescent gambling problem severity measure are described. The scale, based on a revision of the South Oaks Gambling Screen (Lesieur & Blume, 1987), was administered to 1,101 older (ages 15 to 18) Minnesota adolescents as part of a state-wide gambling survey. Study results indicated that the scale had moderate internal consistency reliability and was significantly related to alternate measures of problem severity for male subjects. Because the rate and severity of gambling among females was very low, the psychometric adequacy of the scale for females is not known at this time. The implications of study findings to the conceptual understanding of adolescent gambling problem severity as well as study limitations and future research needs, are discussed.Support for the study was provided by the Minnesota Department of Human Services and the Center for Addiction Studies, University of Minnesota, Duluth. The authors gratefully acknowledge the assistance from Robert Blum, Linda Harris, Durand Jacobs, J. Laundergan, Alan Mathiason, Brenda Miller, James Schaefer, school officials from the participating high schools, and interviewers who assisted with the telephone survey. 相似文献

Las Vegas is a city that has long challenged social norms of the rest of the United States and built a highly successful economic base on gambling and other hedonistic pursuits. Now that many other states and communities are pursuing or actively considering following the route of legal casinos for economic development purposes, the ethical considerations that have confronted Las Vegas about the question of gambling and its broader social impacts take on greater import.This paper examines the ethics of gambling relative to Las Vegas at two levels: first, as a pragmatic trade-off of accepting an activity with some bad consequences because of the economic benefits that can be derived; and second, more fundamentally, by examining the validity of the major ethical arguments against gambling. 相似文献

Ego building is essentially a name given to a variety of interventions used to support an ego hampered by regression or deviation. The term has its roots in the concept of ego support but evolved specifically as a technical term in contemporary ego psychology closely connected with the developmental theory of separation individuation. Using four vignettes of psychotherapy work with children all of whom suffered from unresolved conflicts and developmental interferences from the separation-individuation process, an attempt is made to illustrate the technical place of ego building in psychotherapy with children. It is suggested that the use of ego building, particularly verbalizing adaptive aims facilitates an alliance, supports a safety feeling and positive self-esteem. This contributes to providing a treatment experience that reduces over-stimulation and anxiety and frees the expression and understanding of aggression which ultimately promotes separation-individuation.in private practice.This paper was presented at the Conference on the Continuing Evolution of Psychoanalytic Thought: Infancy to Adulthood, N.Y.C., Nov. 1990., sponsored by the Committee on Psychoanalysis of the National Federation of Societies for Clinical Social Work. 相似文献
