Generalized hypercube structures and hyperswitch communication network

This paper discusses an ongoing study that uses a recent development in communication control technology to implement hybrid hypercube structures. These architectures are similar to binary hypercubes, but they also provide added connectivity between the processors. This added connectivity increases communication reliability while decreasing the latency of interprocessor message passing. Because these factors directly determine the speed that can be obtained by multiprocessor systems, these architectures are attractive for applications such as remote exploration and experimentation, where high performance and ultrareliability are required. This paper describes and enumerates these architectures and discusses how they can be implemented with a modified version of the hyperswitch communication network (HCN). The HCN is analyzed because it has three attractive features that enable these architectures to be effective: speed, fault tolerance, and the ability to pass multiple messages simultaneously through the same hyperswitch controller

The Post Qualifying Social Work Part One Programme might be in murky waters, but that doesn't mean 'throwing the baby out with the bath water', as Keith Brown, Natasha Young and Steven Keen explain

Design and semantics of form and movement (DeSForM 2006)

Design and Semantics of Form and Movement (DeSForM) grew from applied research exploring emerging design methods and practices to support new generation product and interface design. The products and interfaces are concerned with: the context of ubiquitous computing and ambient technologies and the need for greater empathy in the pre-programmed behaviour of the ‘machines’ that populate our lives. Such explorative research in the CfDR has been led by Young, supported by Kyffin, Visiting Professor from Philips Design and sponsored by Philips Design over a period of four years (research funding £87k). DeSForM1 was the first of a series of three conferences that enable the presentation and debate of international work within this field: • 1st European conference on Design and Semantics of Form and Movement (DeSForM1), Baltic, Gateshead, 2005, Feijs L., Kyffin S. & Young R.A. eds. • 2nd European conference on Design and Semantics of Form and Movement (DeSForM2), Evoluon, Eindhoven, 2006, Feijs L., Kyffin S. & Young R.A. eds. • 3rd European conference on Design and Semantics of Form and Movement (DeSForM3), New Design School Building, Newcastle, 2007, Feijs L., Kyffin S. & Young R.A. eds. Philips sponsorship of practice-based enquiry led to research by three teams of research students over three years and on-going sponsorship of research through the Northumbria University Design and Innovation Laboratory (nuDIL). Young has been invited on the steering panel of the UK Thinking Digital Conference concerning the latest developments in digital and media technologies. Informed by this research is the work of PhD student Yukie Nakano who examines new technologies in relation to eco-design textiles

Cross-Border Information Transfers: Evidence from Profit Warnings Issued by European Firms

This paper reports evidence on cross-border accounting information transfers associated with profit warning announcements. Using a sample of firms from 29 European countries, we find that negative earnings surprises disclosed by firms in one country affect investors’ perceptions of comparable nonannouncing firms in other countries. The form and magnitude of cross-border effects is consistent with domestic transfers. Tests explaining variation in cross-border information transfers provide some (albeit rather limited) evidence that effects vary according to a range of firm-, industry- and country-level characteristics.Information transfers; Profit warnings

Serial Persistence in Individual Real Estate Returns in the UK

Persistence of property returns is a topic of perennial interest to fund managers as it suggests that choosing those properties that will perform well in the future is as simple as looking at those that performed well in the past. Consequently, much effort has been expended to determine if such a rule exists in the real estate market. This paper extends earlier studies in US, Australian, and UK markets in two ways. First, this study applies the same methodology originally used in Young and Graff (1996) making the results directly comparable with those in the US and Australian property markets. Second, this study uses a much longer and larger database covering all commercial property data available from the Investment Property Databank (IPD), for the years 1981 to 2002 for as many as 216,758 individual property returns. While the performance results of this study mimic the US and Australian results of greater persistence in the extreme first and fourth quartiles, they also evidence persistence in the moderate second and third quartiles, a notable departure from previous studies. Likewise patterns across property type, location, time, and holding period are remarkably similar leading to the conjecture that behaviors in the practice of commercial real estate investment management are themselves deeply rooted and persistent and perhaps influenced for good or ill by agency effects.

Homeownership, Social Capital and Parental Voice in Schooling

We use New Zealand school board of trustees data to examine whether schools where parents have high rates of homeownership experience high parental voting turnout in elections. We also investigate whether homeownership influences the probability that a school board proceeds to election, indicating parental willingness to serve as a school trustee. Similarly, we examine whether state-owned social housing rates affect these outcomes. We compile results initially without controlling for other factors, and then controlling for a wide range of other characteristics, to test the robustness of simple observed associations between homeownership and state-ownership rates and outcome variables. Our findings show no discernible effect of homeownership on parental voting turnout in school elections after controls are added (contrary to the simple positive association), but a (robust) positive impact of both homeownership and state-ownership rates on the probability that a school holds an election.homeownership, school elections, parental voice, social capital

Included, but Deportable: A New Public Health Approach to Policies That Criminalize and Integrate Immigrants.

There has been a burst of research on immigrant health in the United States and an increasing attention to the broad range of state and local policies that are social determinants of immigrant health. Many of these policies criminalize immigrants by regulating the "legality" of their day-to-day lives while others function to integrate immigrants through expanded rights and eligibility for health care, social services, and other resources.Research on the health impact of policies has primarily focused on the extremes of either criminalization or integration. Most immigrants in the United States, however, live in states that possess a combination of both criminalizing and integrating policies, resulting in distinct contexts that may influence their well-being.We present data describing the variations in criminalization and integration policies across states and provide a framework that identifies distinct but concurrent mechanisms of deportability and inclusion that can influence health. Future public health research and practice should address the ongoing dynamics created by both criminalization and integration policies as these likely exacerbate health inequities by citizenship status, race/ethnicity, and other social hierarchies
