Trimline Trauma: The Wider Implications of a Paradigm Shift in Recognising and Interpreting Glacial Limits

Trimlines mark the boundary between glacially eroded landscapes on low ground and landscapes dominated by evidence of periglacial weathering on higher summits. For many years the trimlines of Scandinavia, Britain and Ireland have been interpreted as marking the surface of the ice sheets at the maximum of the last glaciation, but recent cosmogenic exposure dating of erratics far above the trimlines in NW Scotland shows this to be false. The trimlines in that area must represent an englacial thermal boundary between warm (eroding) ice and cold (protecting) ice. It is now clear that even very experienced geomorphologists cannot necessarily tell the difference between terrain that has been recently glaciated and terrain that has not, because cold-based ice can leave virtually no trace. This calls into question not only the interpretation of high-level trimlines elsewhere, but also the mapping of the lateral limits of past glaciations, which are often based on similar or even weaker geomorphological and sedimentological evidence.     

Geochemical discrimination of basaltic sources as a tool for provenance analyses of bifacial tools in the southern Levant: first results from the Jezreel Valley,Israel

The determination of groundstone tool sources bears the potential to examine aspects like raw material selection and preference, mobility, trade and exchange patterns, control over resources and long term use of raw material sources. The discovery of the Neolithic/Chalcolithic basanite bifacial quarry of Giv'at Kipod in the Jezreel Valley, Israel, provides the opportunity of raw material centred provenance studies of bifacials in the southern Levant. The basis for reliable provenance analyses is a clear geochemical characterization of the extraction site and its discrimination from other potential sources. To achieve this, the Miocene magmatic rocks of the Jezreel Valley were sampled and analysed by XRF and La-ICP-MS. The geochemical evaluation, combined with cluster analyses, resulted in a clear discrimination of the Giv'at Kipod lava from other basaltic sources in the area. Based on the geochemical field data, a Giv'at Kipod provenance for six bifacial tools found in three archaeological sites dated to the Neolithic and the Chalcolithic periods was established. The results suggest that the quarry was in use for several millennia. This pilot study demonstrates that for provenance analyses lava outcrops in the southern Levant can be geochemically discriminated from each other on a very small spatial scale, on the basis of a detailed field sampling and the application of multivariate methods.     

Benefitting from Learning Networks in “Open Innovation”: Spin-off Firms in Contrasting City Regions

R&D and innovation increasingly take place in networks that extend beyond the boundaries of a single firm, with customers in an important role in the learning processes involved. This phenomenon is captured by the term “open innovation”. Advantages of open innovation encompass cost reduction and an increased competitiveness. Spatial innovation theory however indicates that the potential of open innovation is not the same for all urban regions, there may be differences between large metropolitan areas and small cities. In this context, the authors compare university spin-off firms in two contrasting urban regions in Europe, Delft in the Netherlands and Trondheim in Norway (a metropolitan area versus an isolated city) with regard to the profile of their learning networks and the contribution of these networks to growth. Learning networks appear to differ in structure and strength, in spatial configuration and also in the influence on job growth. Thus, networks in Delft (in a large metropolitan area) tend to be stronger compared to those in Trondheim (isolated city), whereas the influence of network strength on growth tends to be negative in Delft but positive in Trondheim. Overall, firms in Trondheim tend to rely more on own resources and capabilities and less on learning networks in open innovation.     

Adjustment or renewal in regional clusters? A study of diversification amongst SMEs in the Aberdeen oil complex

A renewed interest in the spatial clustering or agglomeration of economic activity is evident within economic geography and related fields. This paper considers processes of change within 'mature' regional clusters, developing a conceptual framework which links firm-level strategies to development scenarios at the cluster level through a set of intervening mechanisms. Whange, enabling the cluster to sustain its prosperity, and adjustment which is associated with stagnation and gradual decline. This conceptual framework is applied to an analysis of one key mechanism of change, diversification, as pursued by small and medium-sized enterprises (SMEs) in the Aberdeen oil cluster. Our analysis indicates that some diversification is occurring, with the implications for the cluster lying midway between adjustment and renewal. In conclusion, we emphasize the need to assess and 'unpack' the clusters concept and suggest that research should focus on the relationships between proximity, learning and evolution.     

Suicide: the spatial and social components of despair in Britain 1980–2000

In this paper we show that, by accounting for the varying influence of just three area indicators of social isolation, it is possible to predict the number of deaths due to suicide and undetermined injuries (most of which are suicides) across a great many areas remarkably closely. The exceptions to this model suggest that in a few unique areas of the country other local, often historical and cultural or intrinsically geographical factors matter also. These findings of the general predictability of suicide matter because suicide is such a common cause of death, particularly for the young. Between 1 January 1981 and 31 December 2000, the underlying cause of the deaths of 130 000 people in Britain were recorded as being directly due to suicide, or in all probability being due to suicide. Collectively, these thousands of personal stories are brought together here to show how a pattern of despair in Britain over this period was spread across the country, affecting different places and different groups in society to differing extents over changing times. The changing geography of despair can be shown to be largely the product of changing economic, social and demographic geographies. This paper is concerned with determining the extent to which the stories of suicide in Britain were more than the sum of thousands of individual acts of misery and the extent to which they reflected the changing social structure of the country. Quantitative analysis is used to identify possible key trends with a more qualitative set of interpretations placed on the possible meanings of these findings. The paper concludes by speculating on how current social trends may influence the future map of the extremes of despair in Britain.     

Labour electoral landslides and the changing efficiency of voting distributions

The translation of votes into seats under first–past–the–post electoral systems with single–member constituencies invariably results in disproportional allocations of seats relative to votes among the main two parties. It also tends to produce biased outcomes, with one party getting a more disproportionate share of the seats with a given share of the votes than does its opponent. In Great Britain, these biases favoured the Conservative party until the 1980s, but now strongly favour Labour. Production of those biases results from a variety of influences involving the interaction of the geography of party support with that of constituency boundaries. Increasingly, that interaction has favoured Labour: without any explicit manipulation of the constituency map to its own ends, it now benefits substantially from the equivalent of the malapportionment and gerrymandering cartographic abuses typical of the United States, because of its ability to manipulate its vote distribution within the constituency system.
