Against the socio-economic and cultural backdrop of the ongoing Latina/o media “boom,” this critical literature review delineates the location and status of contemporary Latina/o Feminist Media Studies. Departing from a critique of current mainstream Feminist Media Studies research and citational practices, it traces the influence of rapidly expanding transnational Latina/o media markets, the gendering of Latinidad, and transnational feminisms on recent Latina/o Feminist Media Studies scholarship. As it not only breaks with exclusively domestic analyses of intersectionality and accurately reflects twenty-first century media’s transnational orientation, this essay argues that the theoretical paradigms and thematic concerns of Latina/o Feminist Media Studies must ultimately be reframed as central, not marginal, to Feminist Media Studies research. 相似文献
Over the past five years the Artificial Intelligence Center at SRI has been developing a new technology to address the problem of automated information management within real- world contexts. The result of this work is a body of techniques for automated reasoning from evidence that we call evidential reasoning. The techniques are based upon the mathematics of belief functions developed by Dempster and Shafer and have been successfully applied to a variety of problems including computer vision, multisensor integration, and intelligence analysis.
We have developed both a formal basis and a framework for implementating automated reasoning systems based upon these techniques. Both the formal and practical approach can be divided into four parts: (1) specifying a set of distinct propositional spaces, (2) specifying the interrelationships among these spaces, (3) representing bodies of evidence as belief distributions, and (4) establishing paths of the bodies for evidence to move through these spaces by means of evidential operations, eventually converging on spaces where the target questions can be answered. These steps specify a means for arguing from multiple bodies of evidence toward a particular (probabilistic) conclusion. Argument construction is the process by which such evidential analyses are constructed and is the analogue of constructing proof trees in a logical context.
This technology features the ability to reason from uncertain, incomplete, and occasionally inaccurate information based upon seven evidential operations: fusion, discounting, translation, projection, summarization, interpretation, and gisting. These operation are theoretically sound but have intuitive appeal as well.
In implementing this formal approach, we have found that evidential arguments can be represented as graphs. To support the construction, modification, and interrogation of evidential arguments, we have developed Gister. Gister provides an interactive, menu-driven, graphical interface that allows these graphical structures to be easily manipulated.
Our goal is to provide effective automated aids to domain experts for argument construction. Gister represents our first attempt at such an aid. 相似文献
Over the last 30 years, the victims' rights movement has expanded the role of victims in the American criminal justice system. As a result of this movement, judges, prosecutors and parole boards must now hear victims' views at all stages of the criminal justice process, including plea bargains, and sentencing and parole decisions. Legislative efforts have been spearheaded by victims' families, and legislation has been named after deceased victims. Also, victims' families can now view executions in states across the country. The victims' right movement assumes that the criminal justice system should privilege victims' interests over those of society. In so doing, it denies society as a consideration, which is tantamount to a denial of society itself. This article positions victims' rights' denial of society within the current conjuncture, marked as it is by the contradiction between neoliberalism and American liberalism. Victims' rights' denial of society is an expression of the denial of society implicit in American neoliberalism, which seeks to privilege individual interests over those of society. This paper argues that victims' rights is a powerful element of the neoliberal project for three reasons. First, victims' rights imputes the authority of legal discourse to neoliberalism's denial of society. Second, important actors in the rise of neoliberalism have also worked to establish victims' rights. Finally, victims' rights comprehensively circulates throughout America and offers powerful points of identification that incorporate Americans into the victims' rights formation. I explore the denial of society in three victims' rights practices: naming criminal legislation after crime victims and passing such laws in honour of victims; allowing victims' families to view executions; and prosecutors, judges and police personnel making legal decisions according to victims' wishes. I examine the consonant denial of society in three neoliberal practices – monetarism, supply-side economics and welfare reform – and demonstrate how neoliberal advocates like Bill Clinton, Ronald Reagan and Paul Gann worked to advance victims' rights. I also describe the production, consumption and comprehensive circulation of victims' rights texts. Finally, I consider Cultural Studies' unique contribution to legal studies. 相似文献
In this paper we consider a simple linear regression model under heteroscedasticity and nonnormality. A statistical test for testing the regression coefficient is then derived by assuming normality for the random disturbances and by applying Welch's method. Some Monte Carlo studies are generated for assessing robustness of this test. By combining Tiku's robust procedure with the new test, a robust but more powerful test is developed. 相似文献
