James Konow 《Economic inquiry》1994,32(1):146-165
Although Heinrich von Stackelberg is famous for his contributions to the theory of imperfect competition, until recently scant attention has been paid to the life, other theoretical work and political thinking of this National Socialist economist. This paper examines his political economy as well as the events in his life which helped form it. Stackelberg devised a unique defense of fascist economic policy based on neoclassical economic analysis. At the same time, he may be credited with creating a novel theoretical framework for addressing a still unfinished line of inquiry into unstable markets and related informational issues. 相似文献

College students (20 women, 14 men) seeking career counseling services at a university career center participated in this exploratory investigation. A 2 (DISCOVER treatment) × 2 (counseling treatment) research design was used to evaluate the individual and combined effects of DISCOVER (ACT, 1998) and counseling on participants' career decision‐making self‐efficacy and career decision‐making attributional style. Findings revealed a significant effect of the use of DISCOVER on participants' career decision‐making self‐efficacy and their sense of control over the career decision‐making process. Results are discussed regarding the implications for career counseling and ideas for further research in this domain. 相似文献

Summary. In longitudinal studies, missingness of data is often an unavoidable problem. Estimators from the linear mixed effects model assume that missing data are missing at random. However, estimators are biased when this assumption is not met. In the paper, theoretical results for the asymptotic bias are established under non-ignorable drop-out, drop-in and other missing data patterns. The asymptotic bias is large when the drop-out subjects have only one or no observation, especially for slope-related parameters of the linear mixed effects model. In the drop-in case, intercept-related parameter estimators show substantial asymptotic bias when subjects enter late in the study. Eight other missing data patterns are considered and these produce asymptotic biases of a variety of magnitudes. 相似文献

Focusing on funding in culture and the arts, the author identifies a distinctive logic of company support for nonprofit organizations. Business giving is increasingly disciplined around company objectives, giving levels are driven by pretax earnings, and giving decisions are the province of managers who draw advice less from the arts community or public agencies than from other companies. At best, turbulence in government funding has modest effect on corporate support. In turn, change in corporate support has little impact on public backing. The separate logics of corporate and government support imply separate and distinctive long-term development strategies for nonprofit organizations. 相似文献

The physical and psychological effects of Turner's Syndrome, a female sex chromosome abnormality, briefly are described. Principles for helping women master the special challenges posed by the disorder are discussed. The authors argue that women with TS must take control of defining their identities and potential in order to attain full status within society. 相似文献

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
