LIFETIME MOBILITY: INTERRELATIONSHIPS OF LABOUR MOBILITY, RESIDENTIAL MOBILITY AND HOUSEHOLD CYCLE

The existence of interrelations between different mobility forms is generally recognized, but they are not often studied. This article attempts to disentangle the complicated ways in which mobility decisions regarding labour, the house, and home-work travelling are related to each other and to phases in the life cycle. An empirical analysis is carried out from the perspective of individual life histories of employees in the medical sector. Their mobility careers are followed while their biographies unfold through a succession of socio-economic and demographic stages. It is shown how motives and patterns of mobility create and change the composition of certain social life-stage groups and determines who belongs to them.
L'existence d'interrelations entre formes de mobilité différentes est, en général, acceptée mais elle n'est pas souvent investiguée. Cet article vise à décrire d'une manière plus simple les décisions par rapport à la mobilité de travail, au logement et aux dieAplacements logement-travail, ainsi que leurs associations et leurs relations avec les étapes dans le cycle de vie. Une analyse empirique est menée dans la perspective des histoires de vie individuelle des employés du secteur médical. L'his-toire de leur mobilité est tracée et les biographies dévoilées selon une succession d'étapes socio-écono-mique et démographique. II est démontré comment les motifs et modèles de mobilité sont créés et comment ils changent la composition et l'appartenance à certains groupes sociaux durant leur vie.     

COMMUTING LINKS AT LOWER LEVELS OF RURAL SETTLEMENT

The study of commuting links in rural areas of the Non-Chernozem Zone offers a useful approach to the redesign of settlement patterns. Commuting to work is analyzed in 80 primary settlement systems (farm systems) in five rayons of Vologda Oblast. Most of the commuting streams are found to occur toward the central farm settlements within systems and also between adjacent systems, with rural nonfarm places (both industry-based and transport based) offering the principal opportunities for employment. Commuting is analyzed in terms of two indices: a labor-balance index (relating resident population and employment opportunities) and a commuting intensity index (relating the number of commuters to resident population).     

COMMUTING IN SMALL AND MIDDLE-SIZE TOWNS OF SOVIET GEORGIA

The author takes issue with the view expressed by M. I. Artamonov, an archeologist, that an ethnos, or ethnic group, represents a social state rather than a process. In the author's view, ethnos IS a vast system in constant development, which tends to be stabilized by endogamy and undermined by exogamy. An ethnic hierarchy is proposed to illustrate the process of ethnogenesis. It ranges from the lowest order of ethnic grouping, a consortium, through subethnos, ethnos and superethnos to mankind as a whole. Each order in the hierarchy is distinguished by particular forms of associations, trends of development and culminating phases. The concept of ethnos as an ongoing process is illustrated with reference to ethnic change in ancient China and in the Ottoman empire.     

THE POTENTIAL MOBILITY OF HUMAN POPULATIONS

Summary. The interpretation of the findings of archaeological surface survey involves making assumptions about the extent and limits to the mobility of communities, land, and individuals in past times. Recent work in medieval and early modern European history has established both the rates and the causes of mobility in a number of different communities. This paper assembles some rather less conclusive evidence from classical Greece to argue that relatively high rates of mobility of individuals, land and communities should not be excluded when a picture of the society of ancient Greece is conjured up.     

ROCK SURFACE HARDNESS AS AN INDICATION OF EXPOSURE AGE: AN ARCHAEOLOGICAL APPLICATION OF THE SCHMIDT HAMMER*

A Schmidt Hammer was employed in evaluating the surface hardness of rocks which line ancient anthropogenic pit features, known as Pukaskwa pits, on the north shore of Lake Superior, Canada. This technique offers a possible new method of producing relative ana absolute dates for such exposed stone features Analysis of the data has provided a relative chronology for the pit features, representing two distinct construction phases. The range of absolute dates generated from the data indicates that the pits were likely constructed by Blackduck peoples c. 900 to 400 years BP.     

AN ASSESSMENT OF BACK-SCATTERED ELECTRON PETROGRAPHY AS A METHOD FOR DISTINGUISHING MEDITERRANEAN OBSIDIANS

The recent application by Burton and Krinsley (1987) of back-scattered electron (BSE) petrography to obsidians from sources located in the south-western United States established that this method can effectively resolve and characterize included micro-crystalline phases that have proven difficult to analyse by optical thin-section microscopy. In the first extension of their original study, we have examined, using BSE petrography, obsidians from island sources located in the Mediterranean, including sources known to have been exploited in prehistory. Because of the kinetic contrasts on their crystallization, these microcrystalline phases reflect the magmatic history of the obsidian, providing information about superheating, supercooling, sub-solidus processes, and other phenomena. This information is of significance for the chemical analysis of Mediterranean obsidians and also as the basis for a powerful alternative to existing non-destructive analytical methods for the sourcing of archaeological and art-historical obsidian.     

IMAGINATION AS A CATEGORY OF HISTORY: AN ESSAY CONCERNING KOSELLECK'S CONCEPTS OF ERFAHRUNGSRAUM AND ERWARTUNGSHORIZONT

Reinhart Koselleck is an important thinker in part for his attempt to interpret the cultural changes resulting in our modern cultural outlook in terms of the (meta)historical categories of experience and expectation. In so doing he tried to pay equal attention to the static and the changing in history. This article argues that Koselleck's use of “experience” and “expectation” confuses their metahistorical and historical meaning, with the result that his account fails to do justice to the static, to continuity in history, and mischaracterizes what is distinctive of the modern era. As well as reconfiguring the categories of experience and expectation, this essay also introduces a third category, namely, imagination, in between experience and expectation. This is done to render intelligible what is obscure in Koselleck's account, and as a stimulus to a study of history that divides its attention equally between the static and the changing. In fact, it is argued that the category of imagination is pre‐eminently the category of history, on the concrete historical as well as the metahistorical level.
