EXITS FROM HOMEOWNERSHIP: THE EFFECTS OF RACE,ETHNICITY, AND INCOME*

ABSTRACT This paper examines the extent to which populations experiencing low homeownership rates in the U.S. also experience high homeownership exit rates. We determine whether low‐income Hispanic and black households that achieve homeownership are as likely as white and high‐income households to sustain it. Using the Panel Study of Income Dynamics spanning the years 1970–2005, we find that low‐income homeowners consistently have higher homeownership exit rates, Hispanic households have higher raw exit rates prior to but not subsequent to 1997, and a black/white sustainability gap appears to arise post‐1997.     

Taking risks in regions: the geographical anatomy of Europe's emerging venture capital market

Over the past 25 years, the USA has pioneered a new technologicalrevolution, based on large numbers of new small enterprises,financed by a dynamic venture (risk) capital market. The EuropeanUnion, meanwhile, has lagged behind in this sector of economicactivity, and compared to the US innovative small and mediumenterprises appear to find it more difficult to get startedand grow. At a time when regional and local banking systems– traditionally major sources of capital for small andmedium sized enterprises across Europe – are undergoingintense reorganisation and restructuring, the European Commissionconsiders the development of a substantial risk capital marketto be a key condition for closing the ‘enterprise gap’with the US. While the venture capital industry is much lessdeveloped in Europe than it is in the US, nevertheless it hasrecently experienced a marked increase in activity. But whereasthe European Commission argues that venture capital activityneeds to be much more regionally clustered if it is to emulatethe US experience, the OECD and some EU member states have arguedfor a more even regional distribution. The aim of the paperis to chart the growth and geographical anatomy of the emergingEuropean venture capital market, and to examine its spatialdevelopment and regional implications in the context of thesesomewhat opposing views.     

Scales and networks of neoliberal climate governance: the regulatory and territorial logics of European Union emissions trading

The growing influence of neoliberal approaches to environmental governance has significantly increased the involvement of industry non-state actors in international and national climate governance. However, the implications of this neoliberalisation and hybridisation of climate governance, and particularly state–industry relations during these processes, remain under-integrated with wider geographical debates on the scalar and network politics of environmental governance. In this paper, we probe these issues by examining the regulatory and territorial logics underpinning the negotiation and implementation of the European Union emissions trading scheme (EU ETS). We argue that overlapping interpretations of the regulatory logic of emissions trading (as a cost-effective means of meeting climate objectives) by EU, state and industry actors provided the driving force for the creation of a Europeanised climate governance space and the consolidation of the EU's governing authority in respect of the formal rule-making elements of the EU ETS. However, alliances between state and industry actors, based around intersecting interpretations of their territorial interests in relation to emissions trading, strongly influenced the scheme's design. Moreover, speculative behaviour within the EU ETS market indicates the continued ability of market networks to disrupt territorially-based climate governance regimes. We argue that critical exploration of the territorial logics and practices of EU emissions trading from regime creation to operation provides new insights into the emerging spatial politics of neoliberal environmental governance and its implications for climate protection.     

Genetic relationships based on discrete dental traits: Basketmaker II and Mimbres

Investigations of the relationships between culture and biology among prehistoric populations of the southwestern United States can enhance our reconstruction of social interactions. The present study analyses the permanent dentition of Basketmaker II and Mimbres individuals from multiple sites using the Arizona State University dental anthropology system, and compares them with a regional sample. Discrete dental trait analysis provides a useful means for assessing the degree of genetic relatedness between populations when large comparative samples are available. Both in situ cultural change and population replacement have been posited as the dominant mechanism acting on Basketmaker and early Puebloan groups. We examine the relationship of these populations to probable Uto‐Aztecan speakers in light of the Uto‐Aztecan farmer migration hypothesis. The Basketmaker II complex, traditionally recognised as a distinct cultural unit, exhibits considerable population heterogeneity. Western Basketmakers appear to share biological ties with Uto‐Aztecan speakers, while Eastern Basketmakers do not, as predicted by the model. The relationship of the Mimbres to probable Uto‐Aztecan speakers is less clear because the Mimbres show only weak affinities to northern Mexican populations.

Sub‐micron spongiform porosity is the major ultra‐structural alteration occurring in archaeological bone

Total pore volume and pore size distribution are indicators of the degree of post‐mortem modification of bone. Direct measurements of pore size distribution in archaeological bones using mercury intrusion porosimetry (HgIP) and back scattered scanning electron microscopy (BSE‐SEM) reveal a common pattern in the changes seen in degraded bone as compared to modern samples. The estimates of pore size distribution from HgIP and direct measurement from the BSE‐SEM images show remarkable correspondence. The coupling of these two independent approaches has allowed the diagenetic porosity changes in human archaeological bone in the >0.01 µm range to be directly imaged, and their relationship to pre‐existing physiological pores to be explored. The increase in porosity in the archaeological bones is restricted to two discrete pore ranges. The smaller of these two ranges (0.007–0.1 µm) lies in the range of the collagen fibril (0.1 µm diameter) and is presumably formed by the loss of collagen, whereas the larger pore size distribution is evidence of direct microbial alteration of the bone. HgIP has great potential for the characterization of microbial and chemical alteration of bone. Copyright © 2002 John Wiley & Sons, Ltd.
