Keeping Our Ambition Under Control: The Limits of Data and Inference in Searching for the Causes and Consequences of Vanishing Trials in Federal Court

JOURNAL OF EMPIRICAL LEGAL STUDIES, Issue 3 2004
Stephen B. Burbank
This article offers some reflections stimulated by Professor Galanter's materials, which were the common springboard for the Vanishing Trials Symposium. It suggests that other data, quantitative and qualitative, may be helpful in understanding the vanishing trials phenomenon in federal civil cases, notably data available for years prior to 1962, and questions whether it is meaningful to use total dispositions as the denominator in calculating a trial termination rate. The article argues that care should be taken in using data from state court systems, as also data from criminal cases, administrative adjudication, and ADR, lest one put at risk through careless assimilation of data or muddled thinking a project quite difficult enough without additional baggage. The article describes the limitations of data previously collected by the Administrative Office of the U.S. Courts and highlights unique opportunities created by the AO's switch to a new Case Management/Electronic Case Files system. It argues that Professor Galanter may underestimate the influence of both changing demand for court services (docket makeup) and of changing demand for judicial services (resources) on the trial rate. Finally, the article argues that conclusions about either the causes or consequences of the vanishing trials phenomenon in federal civil cases are premature, suggesting in particular reasons to be wary of emphasis on "institutional factors" such as the discretionary power of first-instance judges and the ideology of managerial judging.

Principles for Public Management Practice: From Dichotomies to Interdependence

GOVERNANCE, Issue 3 2001
Martha S. Feldman
In this essay we explore the relationship between management practices and a basic governance dilemma: how to manage flexibly and accountably. The challenge is both practical and theoretical. Managers must respond flexibly to the changing demands and expectations of the public and the ever-changing nature of public problems, yet they must do so in a manner that provides accountability to the public and political overseers. A dichotomous approach to the study of leadership as management action and the governance structures within which managers operate has inhibited the search for a public management theory that reconciles the dilemma. Emphasis upon managers as leaders typically focuses on the flexible actions managers might take to overcome structural "barriers," while emphasis upon governance structures typically focuses on the essential role of structure in ensuring accountability and restraining or motivating particular management efforts. The practicing manager, however, cannot deal with these aspects of the work separately. Managers must attend to demands for both flexible leadership action and structures that promise accountability. Anecdotal evidence provides illustrations of some of the ways that managers can integrate these demands. We suggest that these efforts point to an alternative theoretical framework that understands action and structure as mutually constitutive, creating a dynamic tension in which attention to one requires attention to the other.

Rethinking mental health nursing education in Australia: A case for direct entry

INTERNATIONAL JOURNAL OF MENTAL HEALTH NURSING, Issue 3 2005
Cynthia Stuhlmiller
ABSTRACT:, Desperate times call for creative solutions. The mental health workforce shortage has created an opportunity to rethink current and future education and training needs in order to prepare competent and compassionate practitioners to meet the changing demands of consumers and their carers requiring mental heath treatment and support. This article urges consideration of an undergraduate direct entry mental health programme similar to that of midwifery or the nursing foundation/mental health branch programmes of the UK. [source]


Release of Ca 2+ from Mitochondria via the Saturable Mechanisms and the Permeability Transition

IUBMB LIFE, Issue 3-5 2001
Douglas R. Pfeiffer
Abstract The literature, reviewed in the previous article, supports three physiological roles for sequestration of calcium by mitochondria: 1) control of the rate of ATP production, 2) activation of the Ca 2+ -induced mitochondrial permeability transition (PT), and 3) modulation of cytosolic Ca 2+ transients. Removal of Ca 2+ from mitochondria permits rapid and efficient changes in the rate of ATP production to adapt to changing demands and can reverse the process of PT induction. Two separate, saturable mechanisms for facilitating Ca 2+ efflux from mitochondria exist. In addition, the permeability transition or PT, which may also remove Ca 2+ from the mitochondrial matrix, is intimately involved in other important functions such as apoptosis. Here we briefly review what is known about these important mitochondrial mechanisms and from their behavior speculate on their possible and probable functions. [source]


Functional morphology and patterns of blood flow in the heart of Python regius,

JOURNAL OF MORPHOLOGY, Issue 6 2009
J. Matthias Starck
Abstract Brightness-modulated ultrasonography, continuous-wave Doppler, and pulsed-wave Doppler-echocardiography were used to analyze the functional morphology of the undisturbed heart of ball pythons. In particular, the action of the muscular ridge and the atrio-ventricular valves are key features to understand how patterns of blood flow emerge from structures directing blood into the various chambers of the heart. A step-by-step image analysis of echocardiographs shows that during ventricular diastole, the atrio-ventricular valves block the interventricular canals so that blood from the right atrium first fills the cavum venosum, and blood from the left atrium fills the cavum arteriosum. During diastole, blood from the cavum venosum crosses the muscular ridge into the cavum pulmonale. During middle to late systole the muscular ridge closes, thus prohibiting further blood flow into the cavum pulmonale. At the same time, the atrio-ventricular valves open the interventricular canal and allow blood from the cavum arteriosum to flow into the cavum venosum. In the late phase of ventricular systole, all blood from the cavum pulmonale is pressed into the pulmonary trunk; all blood from the cavum venosum is pressed into both aortas. Quantitative measures of blood flow volume showed that resting snakes bypass the pulmonary circulation and shunt about twice the blood volume into the systemic circulation as into the pulmonary circulation. When digesting, the oxygen demand of snakes increased tremendously. This is associated with shunting more blood into the pulmonary circulation. The results of this study allow the presentation of a detailed functional model of the python heart. They are also the basis for a functional hypothesis of how shunting is achieved. Further, it was shown that shunting is an active regulation process in response to changing demands of the organism (here, oxygen demand). Finally, the results of this study support earlier reports about a dual pressure circulation in Python regius. J. Morphol., 2009. © 2008 Wiley-Liss, Inc. [source]
