A CITY IN MOTION: TIME-SPACE ACTIVITY AND MOBILITY PATTERNS OF SUBURBAN INHABITANTS AND THE STRUCTURATION OF THE SPATIAL ORGANIZATION OF THE PRAGUE METROPOLITAN AREA

This contribution attempts to reveal the relations between new suburban areas and other parts of the Prague metropolitan area by investigating the time‐space activity and mobility patterns of the inhabitants of newly built suburban districts. The focus on some aspects of the everyday life of people in new suburbs helps us to identify the impact of suburbanization on the changing geography of the metropolitan region and to better understand how the spatial organization of the Prague metropolitan area is produced, reproduced and transformed. We use several interrelated concepts, which serve the theoretical foundation of our work, namely time geography, structuration theory and the post‐communist city. The empirical data utilized are primarily based on 262 diaries completed by eighty‐eight individuals from thirty‐eight households, accompanied by household questionnaires and interviews with the heads of households. The research confirmed the implicit, generally unspoken view that new suburbs in the Prague metropolitan region are heavily dependent on the core of the metropolitan area for the provision of jobs and services. However, newly built suburban shopping facilities to some extent disrupt this pattern, keeping some daily activities of inhabitants within the suburban zone. In addition to empirical observations, the key purpose of this contribution has been to discuss and apply time geography concepts and methods to the research of urban restructuring, and to understand the structuration of metropolitan spatial organization.     

STATE REVENUE ELASTICITY AND EXPENDITURE GROWTH

Recent analyses and theories of public choice suggest faster public sector expansion in states with highly elastic revenue structures. This paper estimates the contribution of elasticity of tax revenues to the growth of expenditures in the 50 American states since 1960, based on elasticity measures for state revenue sources compiled by the Advisory Commission on Intergovernmental Relations, an index of state tax structural change, and controls for federal aid to states, population increase, and per capita growth in real income. Results for 1960-1970 show a small positive relationship between revenue elasticity and expenditure growth, but this becomes weak and negative for 1970-1976. Spending has increased most in states with the least elastic revenue sources; these states have made considerable changes in tax laws, while states with elastic revenue sources have been more likely to cut taxes than to increase spending. Federal aid, rather than tax elasticity, is the best predictor of state expenditure growth, while legislative changes in tax structure have enabled states to keep pace with rising demand for revenue due to growth in population and real income.     

La controverse de Grotius,Hobbes et Spinoza sur le <Emphasis Type="Italic">jus circa sacra</Emphasis> textes,prétextes,contextes et circonstances

In this contribution, I sketch out a methodological framework for the study of controversies in the history of philosophy. It is built around four basic components: texts, contexts, pretexts and circumstances. I show how, once these four elements have been identified and systematically distinguished and distributed, a controversy has been localized and circumscribed. I show, moreover, how controversies are formally linked to each other through the migration of texts from one context to another. Next, I take as an example the controversy on the jus circa sacra, or “right of holy matters,” a key controversy in the political philosophy of the early modern period, focusing in particular on the work by Grotius, Hobbes and Spinoza.     

Do EU funds crowd out other public expenditures? Evidence on the additionality principle from the detailed Czech municipalities’ data

European Union (EU) funds flowing into budgets of public sector organizations of its member states should be additional to their nationally funded expenditures. To investigate this additionality principle systematically, we develop a new empirical method. Our main hypothesis is that some of the EU-funded projects are crowding out national public expenditures. Not being able to reject the hypothesis would be consistent with violating the additionality principle. To test the hypothesis, we examine how EU funding translates into actual spending of relatively comparable municipalities of the Czech Republic. We innovatively match the municipal authorities’ budgetary data on EU-funded expenditure projects with their other, nationally funded, expenditures. We find no systemic crowding out of national public expenditures by EU funds at the level of operational programmes in the Czech municipalities’ data, which is consistent with no evidence of violating the additionality principle. Nonetheless, going down to the municipal level enables us to show how the results can pinpoint individual cases of EU fund’s potential mismanagement in Czech municipalities. Overall, we provide the first evaluation of the additionality principle at the level of individual recipients of EU funds and in doing so we develop a methodological approach potentially applicable to other fund recipients.     

Shellfish exploitation in Stone Age Arctic Norway: procurement patterns and household activities

Archaeological evidence for coastal shellfish exploitation in Arctic Norway mostly dates from 5300 to 1500 BC, encompassing the terminal Mesolithic, the Late Stone Age, and the beginning of the Early Metal Period. Shell middens are generally associated with semi-subterranean houses, but may also occur as free-standing deposits. The primary shellfish taxa exploited were Littorina littorea, Arctica islandica and Mytilus edulis. Most of the species utilized were available in the littoral zone and were easily procured in the course of daily household activities, but sub-littoral A. islandica would have required greater investment in procurement technology and time, as well as labor cooperation. Shellfish were an occasional dietary supplement and could also serve as fishing bait. Spatial and temporal variation in shellfish assemblages reflects local marine ecology, sea-level changes, household dynamics, and perhaps field processing. Interpretation of the existing data is constrained by inadequate midden sampling and documentation methods.     

Insights into the processes behind the contamination of degraded human teeth and bone samples with exogenous sources of DNA

A principal problem facing human DNA studies that use old and degraded remains is contamination from other sources of human DNA. In this study we have attempted to contaminate deliberately bones and teeth sampled from a medieval collection excavated in Trondheim, Norway, in order to investigate this poorly understood phenomenon. Five pairs of teeth and bone samples were bathed in water containing various concentrations (from 10⁻⁹ and 10⁻²¹ g/l) of purified ΦX174 DNA. Subsequently the samples were subjected to a routine decontamination protocol involving a bleach bath followed by exposure to λ=254 nm ultraviolet light, prior to DNA extraction and analysis for evidence of the persistence of the contaminant. The results support previous speculation that bone is more susceptible to water‐borne sources of contaminant DNA, although both bone and teeth are readily contaminated and are difficult to decontaminate using the tested protocol. We believe that this is largely due to the porous nature of bone and teeth facilitating the deep penetration of the contaminant DNA. To simulate a more realistic handling situation, 27 further teeth were directly handled and washed, then decontaminated, prior to assaying for the residual presence of the handler's DNA. Surprisingly, although our results suggest that a large proportion of the teeth were contaminated with multiple sources of human DNA prior to our investigation, we were unable to contaminate the samples with further human DNA. One potential explanation may be the deposition of sediment or other structural changes that occur within the samples as they desiccate post‐excavation, which may protect samples from subsequent contamination, but also prevent the efficacy of bleach baths in decontaminating specimens.
