INTRA-REGIONAL EMPLOYMENT GROWTH IN LUXEMBOURG (1994–2005)

The specialization of city-centres towards more advanced service activities has mostly been studied in the largest city-regions, the case of smaller urban centres being less well documented. In that context, the objective of this article is to analyse the role of sectoral and regional factors in employment growth in Luxembourg between 1994 and 2005. Using statistical data from the Luxembourg General Inspection of Social Security, this contribution distinguishes 12 categories of manufacturing industries and services according to an OECD-Eurostat knowledge-based classification. Five intra-regional areas are distinguished based on morphological and functional criteria in the Luxembourg Metropolitan Area. Using several indexes, this article first analyses the sectoral specialization and geographical concentration of employment. A model of intra-regional employment growth, initially developed by Marimon and Zilibotti and applied at the European level, is then shown to account for 40 per cent of employment growth. An estimation of the contributions of sectoral and geographical factors highlights the primacy of the latter over the former. Finally, the construction of virtual economies confirms the City's overall lower performance as compared to its close periphery. Results underscore a process of functional integration in the Luxembourg metropolitan area: as the core of the city undergoes a specialization process, the urban area benefits from a relocation of activities less sensitive to distance and transaction costs, while the periphery becomes increasingly diversified, notably in the South where traditional industrial activities are being replaced by service activities. These results suggest that the evolution pattern of employment growth in Luxembourg is very similar to that of some larger metropolitan centres, owing to its exceptional financial service activities.     

WHAT SCALE MATTERS? EXPLORING THE RELATIONSHIPS BETWEEN INDIVIDUALS' SOCIAL POSITION,NEIGHBOURHOOD CONTEXT AND THE SCALE OF NEIGHBOURHOOD

Over the past few years, neighbourhood effects research has received significant attention from the academic world, not only in the US, where that attention has a longer tradition, but also in Western Europe. There is also substantial interest among policy makers. Most policy makers intend to reduce concentrations of poverty by enhancing the social mix of neighbourhoods. Avoiding high immigrant concentrations in particular neighbourhoods is another issue that fuels political debate and policy intervention in many Western European countries, Scandinavian countries included. However, there are clear gaps in the understanding of the relationship between neighbourhood composition and social outcomes. One of these gaps regards the scale of the neighbourhood; if there would be neighbourhood effects, what scale is it relevant to consider? Is mix good or bad for the social prospects of individuals at a level that is very local, for example a few neighbouring streets, or could mix be helpful at a somewhat higher scale? This article will focus on this issue, applying individual longitudinal data in multi‐level models for the entire active population of the three largest metropolitan areas in Sweden. We will explore the degree to which the social and ethnic composition of geographical districts, at a variety of scales (measured at time t), are statistically related to individual employment and earnings for adult metropolitan residents at time t+1, controlling for relevant personal and household characteristics.

Experimental patterns of hammerstone percussion damage on bones: implications for inferences of carcass processing by humans

The common occurrence of hammerstone percussion damage (pits, striae, notches and impact flakes) on the fossil limb bones of ungulates indicates that marrow extraction has been an important component of hominid butchery for over two million years. Beyond this level of basic inference, it would be behaviorally informative if three deeper aspects of marrow harvesting were understood more clearly: (1) whether inter-element patterns of bone fragmentation vary when processing intensity is held constant; (2) whether butcher investment in marrow extraction correlates positively with the number of percussion marks generated; (3) whether taphonomic effectors can be identified based on percussion mark morphology, frequency and placement. Some experimental work has been conducted previously in service of exploring these questions, but we set out here to address them explicitly through the analysis of a large sample of white-tailed deer (Odocoileus virginianus) limb elements fractured by hammerstone percussion. Our results indicate that (1) measures of bone fragmentation, which supposedly reflect processing intensity, are highly contingent on the research question being posed. This stresses the fact that researchers must be explicit in their definition of processing intensity. (2) In addition, hypothesized covariance between number of hammerstone blows and percussion mark frequencies are not met in our sample, corroborating previous conclusions of a lack of covariance between cutting strokes and cutmark frequencies. These results highlight the contingent nature of butchery mark production, and emphasize the need to investigate carcass resource exploitation by posing questions that do not rely on mark frequencies, but instead utilize other zooarchaeological measures. (3) Finally, our results—showing high incidences of impact notches and flakes created by direct anvil contact and “anvil scratches” created by direct hammerstone contact—suggest caution in using specific categories of percussion damage to infer their taphonomic effectors.     

Computational Comparison of Five Maximal Covering Models for Locating Ambulances

This article categorizes existing maximum coverage optimization models for locating ambulances based on whether the models incorporate uncertainty about (1) ambulance availability and (2) response times. Data from Edmonton, Alberta, Canada are used to test five different models, using the approximate hypercube model to compare solution quality between models. The basic maximum covering model, which ignores these two sources of uncertainty, generates solutions that perform far worse than those generated by more sophisticated models. For a specified number of ambulances, a model that incorporates both sources of uncertainty generates a configuration that covers up to 26% more of the demand than the configuration produced by the basic model.     

Identity,class and civil society in Scotland’s neo‐nationalism

Civil society has become a central and contested concept in the study of Scottish nationalism. This article aims to scrutinise and qualify the concept by relating it to Weber’s model of classes, status groups and parties, and by exploring the development of Scotland’s civil society along with the welfare state in the twentieth century. It argues that civil society needs to be understood as a zone of status‐group formation, and that attempts to relate ‘class’ and ‘identity’ to support for constitutional change in Scotland need to be complemented by attention to the role of status groups in civil society. It concludes with the suggestion that such an approach might be fruitful in the study of other cases of neo‐nationalism.
