A model for the distributed storage and processing of large arrays

A conceptual model for parallel computations on large arrays is developed. The model provides a set of language concepts appropriate for processing arrays which are generally too large to fit in the primary memories of a multiprocessor system. The semantic model is used to represent arrays on a concurrent architecture in such a way that the performance realities inherent in the distributed storage and processing can be adequately represented. An implementation of the large array concept as an Ada package is also described

From International Treaties to Internet Norms: The Evolution of International Trademark Disputes in the Internet Age

In today\u27s dynamic, digital economy, there is a global clash between geographically bounded intellectual property rights and the limitless reach of the Internet. Traditionally, discrepancies in international intellectual property rights, such as trademark disputes, have been resolved through time-consuming, multilateral state-to-state treaty negotiations that have global harmonization as the primary goal. With the explosion of e-commerce and the birth of a New Economy, however, such a traditional process is no longer economically viable. Instead, a new approach towards international intellectual property is fast emerging - one that rests not on treaties between multiple states, but on the private contracting of individuals and the social norms of the cyberspace community. This article explores how this new approach of private ordering and Internet social norms operates in the arena of international trademark disputes. The Uniform Domain Name Dispute Resolution Policy recently established by the Internet Corporation for Assigned Names and Numbers provides an example of how private contracts have come to replace the sovereignty of nation-states in the resolution of international trademark disputes. Analyzing this new policy in detail, this article concludes that international trademarks are just one aspect of a greater trend - fostered by the Internet - away from top-down administration and towards a more democratic, and perhaps even populist, mode of decision making

Selection in the Presence of Implicit Bias: The Advantage of Intersectional Constraints

In selection processes such as hiring, promotion, and college admissions, implicit bias toward socially-salient attributes such as race, gender, or sexual orientation produces persistent inequality and reduces utility for the decision-maker. Recent works show that interventions like the Rooney Rule, which require a minimum quota of individuals from each affected group, are very effective in improving utility when individuals belong to at most one affected group. However, in several settings, individuals belong to multiple affected groups and, consequently, face more extreme implicit bias due to this intersectionality. We consider independently drawn utilities and show that, with intersectionality, the aforementioned non-intersectional constraints only recover part of the utility achievable in the absenceof implicit bias. On the other hand, we show that appropriate lower-bound constraints on the intersections recover almost all the utility achievable in the absence of implicit bias. And, hence, offer an advantage over non-intersectional approaches to reducing inequality

Intersectional anti racist advocacy practice in healthcare organizations

Health care organizations, like individuals, can evolve to become antiracist and promote racial equity within and beyond the organization. In this brief article, we introduce an intersectional antiracist advocacy practice framework applicable to health care organizations that seek restorative and transformative change, as well as participation in social and economic justice action. Becoming an antiracist organization requires an acknowledgment that no organization is impervious to racist and other oppressive ideologies. Organizations can then begin to interrogate, interrupt, and address how racism permeates agency policies, procedures, and culture. The implementation of an intersectional antiracist advocacy practice framework within organizations involves a multifaceted approach, including both internal and external practices. Internally facing practices include providing mandatory antiracist trainings to all employees; promoting a representative and equitable workplace; and developing an organizational power structure based on inclusion, transparency, and accountability. Externally facing practices include fostering nonexploitative, reciprocal community partnerships; contributing to social and economic justice movements; and demonstrating transparency and accountability for the negative impact of operations in Black, Indigenous, and People of Color (BIPOC) communities and lands. We conclude with key questions for health care organizations to consider in regard to their racial equity efforts, specifically around organizational readiness, risk tolerance, and long-term commitment

Network-based dissolution

We introduce a novel graph-theoretic dissolution model which applies to a number of redistribution scenarios such as gerrymandering or work economization. The central aspect of our model is to delete some vertices and redistribute their "load" to neighboring vertices in a completely balanced way. We investigate how the underlying graph structure, the pre-knowledge about which vertices to delete, and the relation between old and new "vertex load" influence the computational complexity of the underlying easy-to-describe graph problems, thereby identifying both tractable and intractable cases

Use of social audits to examine unofficial payments in government health services: experience in South Asia, Africa, and Europe

<p>Abstract</p> <p>Background</p> <p>Unofficial payments in health services around the world are widespread and as varied as the health systems in which they occur. We reviewed the main lessons from social audits of petty corruption in health services in South Asia (Bangladesh, Pakistan), Africa (Uganda and South Africa) and Europe (Baltic States).</p> <p>Methods</p> <p>The social audits varied in purpose and scope. All covered representative sample communities and involved household interviews, focus group discussions, institutional reviews of health facilities, interviews with service providers and discussions with health authorities. Most audits questioned households about views on health services, perceived corruption in the services, and use of government and other health services. Questions to service users asked about making official and unofficial payments, amounts paid, service delivery indicators, and satisfaction with the service.</p> <p>Results</p> <p>Contextual differences between the countries affected the forms of petty corruption and factors related to it. Most households in all countries held negative views about government health services and many perceived these services as corrupt. There was little evidence that better off service users were more likely to make an unofficial payment, or that making such a payment was associated with better or quicker service; those who paid unofficially to health care workers were not more satisfied with the service. In South Asia, where we conducted repeated social audits, only a minority of households chose to use government health services and their use declined over time in favour of other providers. Focus groups indicated that reasons for avoiding government health services included the need to pay for supposedly free services and the non-availability of medicines in facilities, often perceived as due to diversion of the supplied medicines.</p> <p>Conclusions</p> <p>Unofficial expenses for medical care represent a disproportionate cost for vulnerable families; the very people who need to make use of supposedly free government services, and are a barrier to the use of these services. Patient dissatisfaction due to petty corruption may contribute to abandonment of government health services. The social audits informed plans for tackling corruption in health services.</p
