We consider the online matching problem, where n server-vertices lie in a metric space and n request-vertices that arrive over time each must immediately be permanently assigned to a server-vertex. We focus on the egalitarian bottleneck objective, where the goal is to minimize the maximum distance between any request and its server. It has been shown that while there are effective algorithms for the utilitarian objective (minimizing total cost) in the resource augmentation setting where the offline adversary has half the resources, these are not effective for the egalitarian objective. Thus, we propose a new Serve-or-Skip (SoS) bicriteria analysis model, where the online algorithm may reject or skip up to a specified number of requests, and propose two greedy algorithms: GriNN(t) and \({{\textsc {Grin}}^*(t)}\). We show that the SoS model of resource augmentation analysis can essentially simulate the doubled-server-capacity model, and then examine the performance of GriNN(t) and \({\textsc {Grin}^*(t)}\). 相似文献

By 2010, when the Greek sovereign debt crisis changed into an existential crisis of the euro, all developed democracies entered a phase in which they had to consolidate their budgets, typically implying a politics of austerity. The scholarly literature, as well as the popular press, suggests that – consequently – welfare retrenchment and cost containment became the only games left in town. In this article, we study the welfare state reform measures taken between 2010 and 2012 in four countries characteristic of mature welfare state regimes (liberal, UK; conservative, Germany; social democratic, Denmark; and hybrid, the Netherlands) to examine empirically whether austerity has indeed become the only item left on the policy menu. Our analysis reveals that retrenchment features prominently on the agenda everywhere, but nowhere by itself. While compensation for income loss is rare since 2010, this still happens. More unexpectedly, reforms in line with a social investment agenda (like expansion of child care or active labour market policies) are still being pursued in all our four cases. 相似文献

The legalization of American Indian casino gaming in the late 1980s allows examination of the relationship between income
and health in a quasi-experimental way. Revenue from gaming accrues to individual tribes and has been used both to supplement
tribe members’ income and to finance tribal infrastructure. We assembled annual data from 1988–2003 on tribal gaming, health
care access (from the Area Resource File), and individual health and socioeconomic characteristics data (from the Behavioral
Risk Factors Surveillance System). We use this information within a structural, difference-in-differences framework to study
the effect of casino gaming on tribal members’ income, health status, access to health care, and health-related behaviors.
Our difference-in-differences framework relies on before-after comparisons among American Indians whose tribe has at some
time operated a casino and with-without comparisons between American Indians whose tribe has and those whose tribe has not
initiated gaming. Our results provide identified estimates of the positive effect of gaming on American Indian income and
on several indicators of American Indian health, health-related behaviors, and access to health care. 相似文献

This paper introduces a new modified Lee-Carter model for analysing short-base-period mortality data, for which the original Lee-Carter model produces severely fluctuating predicted age-specific mortality. Approximating the unknown parameters in the modified model by linearized cubic splines and other additive functions, the model can be simplified into a logistic regression when fitted to binomial data. The expected death rate estimated from the modified model is smooth, not only over ages but also over years. The analysis of mortality data in China (2000-08) demonstrates the advantages of the new model over existing models. 相似文献

Radio frequency identification (RFID) has been used to improve business supply chain management for over 35 years. As often
happens, private sector technology migrates to the public sector where it is adapted for use. RFID use in governments is spreading
far and wide at the federal and state levels with virtually no debate or performance analyses to inform adoption decisions.
Implementation of RFID technology impacts government efficiency and effectiveness in many areas. Data show that most RFID
applications promise enhanced effectiveness but also pose increased costs. A model is constructed to assist state and local
managers in choosing to adopt RFID and to discern the status and impacts of this bold new innovation.

Online education is becoming commonplace in the academic world. Schools now offer totally online degree programs or provide a hybrid of face-to-face and online courses for fulfilling academic requirements. Developing courses and teaching online requires instructors to rethink the educational paradigms they have relied upon in the past. The Net Generation of learners brings a different set of expectations, styles, and needs to the classroom than those of previous generations; this mandates that instructors redesign courses and use contemporary teaching modalities. This article describes how film was successfully used as the primary medium to teach a graduate online Social Work course, Death and Grief. 相似文献

Eleven typically developing children were assessed on the accuracy of prompted self-echoic responses following a 5-s delay from their initial echoic response, replicating procedures in Esch, Esch, McCart, and Petursdottir (2010) that compared discrepancies between echoic and self-echoic scores of autistic and typically developing children following a 2-s delay. We compared the two studies in terms of age, level tested, and echoic/self-echoic discrepancy scores. Age and test level differences were found to be statistically significant. Results are discussed in terms of discrepant self-echoic performance and self-echoic rehearsal as it relates to participant age, test level, motivating variables, and the development of complex behavior. 相似文献

This paper describes an educational experiment with the placement of second-year students in field settings in the United Kingdom. The practicum assignments were in a rural area of Northern Scotland and in London. The paper also includes a preliminary analysis of the educational goals and the unique personal and professional gains for faculty and students. 相似文献

This article discusses the impact of lesbian mothers' activism on legislation and personal well-being. Using a meaning reconstruction framework, the activism of lesbian parents is evaluated as a source of resilience and strength in the current political climate. A case history of one community where lesbian mothers formed a local coalition in response to a statewide proposition to ban same-sex marriage in Texas is described. This community example shows how the activism of lesbian parents can transform both community and activists. Implications for community organizers, therapists and LGBT parents/allies are discussed. 相似文献
