Inference for comparing a multinomial distribution with a known standard

We propose a new type of stochastic ordering which imposes a monotone tendency in differences between one multinomial probability and a known standard one. An estimation procedure is proposed for the constrained maximum likelihood estimate, and then the asymptotic null distribution is derived for the likelihood ratio test statistic for testing equality of two multinomial distributions against the new stochastic ordering. An alternative test is also discussed based on Neyman modified minimum chi-square estimator. These tests are illustrated with a set of heart disease data.     

Life politics,nature and the state: Giddens' sociological theory and The Politics of Climate Change

Anthony Giddens' The Politics of Climate Change represents a significant shift in the way in which he addresses ecological politics. In this book, he rejects the relevance of environmentalism and demarcates climate‐change policy from life politics. Giddens addresses climate change in the technocratic mode of simple rather than reflexive modernization. However, Giddens' earlier sociological theory provides the basis for a more reflexive understanding of climate change. Climate change instantiates how, in high modernity, the existential contradiction of the human relationship with nature returns in new form, expressed in life politics and entangled with the structural contradictions of the capitalist state. The interlinking of existential and structural contradiction is manifested in the tension between life politics and the capitalist nation‐state. This tension is key for understanding the failures so far of policy responses to climate change.     

Time-Dose-Response Models for Microbial Risk Assessment

While microbial risk assessment (MRA) has been used for over 25 years, traditional dose-response analysis has only predicted the overall risk of adverse consequences from exposure to a given dose. An important issue for consequence assessment from bioterrorist and other microbiological exposure is the distribution of cases over time due to the initial exposure. In this study, the classical exponential and beta-Poisson dose-response models were modified to include exponential-power dependency of time post inoculation (TPI) or its simplified form, exponential-reciprocal dependency of TPI, to quantify the time of onset of an effect presumably associated with the kinetics of in vivo bacterial growth. Using the maximum likelihood estimation approach, the resulting time-dose-response models were found capable of providing statistically acceptable fits to all tested pooled animal survival dose-response data. These new models can consequently describe the development of animal infectious response over time and represent observed responses fairly accurately. This is the first study showing that a time-dose-response model can be developed for describing infections initiated by various pathogens. It provides an advanced approach for future MRA frameworks.     

Estimation for two-way analysis of variance with correlated errors

We consider some estimation and distribution problems encountered in a two way analysis of variance model with only one observation per cell, errors correlated in one level, and the variances are not necessarily equal. The independence criteria for the row and interaction mean sum of squares and distribution of the maximum likelihood estimator of the correlation coefficient are given.     

Gender, Feminism, and Partisanship among Women's PAC Contributors

Objective . We examine the political attitudes and priorities of contributors to two prominent women's PACs for evidence of a gender gap. Methods . A survey of contributors to EMILY's List and to WISH List shows that contributors to both organizations are overwhelmingly women. However, because EMILY's List is so large, there is a sufficient number of men to compare to the two groups of women using percentages and difference-of-means tests. Results . Partisanship is the overriding influence on political priorities and attitudes toward economic and social welfare policy. However, partisanship and gender interact to influence political attitudes in at least two areas. First, EMILY's List men are more supportive of militarism and use of force than are EMILY's List women, but they are less supportive than WISH List women. Second, the women of EMILY's List are more staunchly feminist than either EMILY's List men or WISH List women. Conclusions . We conclude that the source of each group's financial commitment to women's political equality and reproductive rights is different: for EMILY's List women, it is liberal feminism; for WISH List women, it is libertarianism; and for EMILY's List men, it is general egalitarianism.     

The Role of Social Context in Students' Anticipatory Reaction to a “Fighting Word”

Abstract

On May 11, 1996, ValuJet flight 592 crashed in the Florida Everglades killing all 105 passengers and five crew members. The technical cause of the crash was a fire that erupted after one or more oxygen generators exploded in a cargo compartment. Governmental investigations have indicated that both ValuJet and SabreTech (an airline maintenance company) failed to comply with a host of regulations concerning the presentation, storage, and transportation of hazardous materials by air. More generally, however, the Federal Aviation Administration (FAA) has been found to be negligent in its oversight of airlines by not adequately monitoring the general safety of commercial aircraft as well as by its refusal to institute safeguards and guidelines that would have protected passengers and crews from crashes like that of flight 592. This paper follows the tradition of state-corporate crime theorizing and research by identifying the organizational and structural forces that contributed to the ValuJet crash. This includes an examination of the FAA's contradictory roles as both regulator and supporter of the airline industry, as well as a discussion of both ValuJet's and SabreTech's violations of federal air safety regulations.
