We show that temporal, spatial, and dyadic dependencies amongobservations complicate the estimation of covariance structuresin panel databases. Ignoring these dependencies results in covarianceestimates that are often too small and inferences that may bemore confident about empirical patterns than is justified bythe data. In this article, we detail the development of a nonparametricapproach, window subseries empirical variance estimators (WSEV),that can more fully capture the impact of these dependencieson the covariance structure. We illustrate this approach ina simulation as well as with a statistical model of internationalconflict similar to many applications in the international relationsliterature. 相似文献

This article examines how the recently introduced law on assisted reproduction in Italy, which gives symbolic legal recognition
to the embryo, came about, and how a referendum, which would have repealed large sections of it, failed. The occupation of
the legal space by the embryo is the outcome of a crusade by a well-organised alliance of theo-conservatives. These groups
see in reproductive medicine an uncontrolled interference with their notion of the natural order of things. Such a worldview
requires a total ban on stem cell research, limitation of access to reproductive technologies and repressive laws to govern
the area. This conservative dream scenario has come closer to being realised by the introduction of a law doing all of these
things in the name of the protection of “Life”. In the case of this law, the “life” to be protected is the embryo. In the
name of “Life”, scientific advances and individual liberty have been curbed. The politics of embryo citizenship is a politics
which values the yet to come over the here and now, purgation over pleasure, and the transcendent over the material. 相似文献

In an era of democratic discontent, more and better participation in policy making has become a standard expectation. Yet it is rarely clear what counts as participation, and how the many practices loosely bundled under the label should be understood. This paper has a modest undergrowth‐clearing objective: to examine assumptions behind competing typologies of participation, and to propose a classification framework less laden by idealist notions of democracy. 相似文献
