The Lazy Bureaucrat Scheduling Problem
We introduce a new class of scheduling problems in which the optimization is
performed by the worker (single ``machine'') who performs the tasks. A typical
worker's objective is to minimize the amount of work he does (he is ``lazy''),
or more generally, to schedule as inefficiently (in some sense) as possible.
The worker is subject to the constraint that he must be busy when there is work
that he can do; we make this notion precise both in the preemptive and
nonpreemptive settings. The resulting class of ``perverse'' scheduling
problems, which we denote ``Lazy Bureaucrat Problems,'' gives rise to a rich
set of new questions that explore the distinction between maximization and
minimization in computing optimal schedules.Comment: 19 pages, 2 figures, Latex. To appear, Information and Computatio
Saints, heroes, sages, and villains
This essay explores the question of how to be good. My starting point is
a thesis about moral worth that I’ve defended in the past: roughly, that an action is
morally worthy if and only it is performed for the reasons why it is right. While I
think that account gets at one important sense of moral goodness, I argue here that it
fails to capture several ways of being worthy of admiration on moral grounds. Moral
goodness is more multi-faceted. My title is intended to capture that multi-facetedness:
the essay examines saintliness, heroism, and sagacity. The variety of our
common-sense moral ideals underscores the inadequacy of any one account of
moral admirableness, and I hope to illuminate the distinct roles these ideals play in
our everyday understanding of goodness. Along the way, I give an account of what
makes actions heroic, of whether such actions are supererogatory, and of what, if
anything, is wrong with moral deference. At the close of the essay, I begin to
explore the flipside of these ideals: villainy
‘The Limits of Goodwill’: the Values and Dangers of Revisionism in Keneally’s ‘Aboriginal’ Novels
Ordinary working men...transformed into giants on the rugby field': Individual and Collective Memory in Oral Histories of Rugby League.
As a sport that partly owes its existence to the issue of ‘broken time’, the working life of professional players outside the game is a highly symbolic issue in rugby league. In England financial reality meant that until the 1990s most players at professional level had to combine their career with full time employment away from the sport, often in the communities they represented on the field. To many this helped create a strong communal bond between those who played and watched rugby league and this perception has become a key cultural narrative in the sport’s ‘collective’ memory. This article uses individual narratives from oral history interviews which relate to the working life of professional players outside rugby league to examine the contention advanced by the sociologist Maurice Halbwachs and others that recollections of personal experience are always shaped to fit within the accepted public discourse. A wide range of personal testimonies are considered in order to illustrate how far, as some oral historians have argued, individuals are able to reflect upon the significance of shared experiences in ways which offer alternative perspectives to dominant cultural scripts

Pediatric Thoracic Trauma Mortality in Iraq and Afghanistan Compared to the United States National Trauma Data Bank
INTRODUCTION: The authors compared pediatric thoracic patients in the Joint Theatre Trauma Registry (JTTR) to those in the National Trauma Data Bank (NTDB) to assess differences in patient mortality rates and mortality risk accounting for age, injury patterns, and injury severity. MATERIALS AND METHODS: Patients less than 19 years of age with thoracic trauma were identified in both the JTTR and NTDB. Multiple logistic regression, χ2, Student\u27s t-test, or Mann-Whitney U test were used as indicated to compare the two groups. RESULTS: Pediatric thoracic trauma patients seen in Iraq and Afghanistan (n = 955) had a significantly higher mortality rate (15.1 vs. 6.0%, P \u3c.01) than those in the NTDB (n = 9085). After controlling for covariates between the JTTR and the NTDB, there was no difference in mortality (odds ratio for mortality for U.S. patients was 0.74, 95% CI 0.52-1.06, P = .10). The patients seen in Iraq or Afghanistan were significantly younger (8 years old, interquartile ratio (IQR) 2-13 vs. 15, IQR 10-17, P \u3c.01) had greater severity of injuries (injury severity score 17, IQR 12-26 vs. 12, IQR 8-22, P \u3c.01), had significantly more head injuries (29 vs. 14%, P \u3c.01), and over half were exposed to a blast. DISCUSSION: Pediatric patients with thoracic trauma in Iraq and Afghanistan in the JTTR had similar mortality rates compared to the civilian population in the NTDB after accounting for confounding covariates. These findings indicate that deployed military medical professionals are providing comparable quality of care in extremely challenging circumstances. This information has important implications for military preparedness, medical training, and casualty care
