SPATIAL MOBILITY AND COMMUTING: THE CASE OF TWO‐EARNER HOUSEHOLDS*

ABSTRACT We examine the effects of the spatial configuration of workers' residence and workplace location on intraregional residential and job moving decisions of workers belonging to two‐earner households. We hypothesize that two‐earner households' residential mobility depends positively on the commuting distance of both spouses, but negatively on the distance between workplaces. Further, we hypothesize that workers' job mobility depends positively on the worker's commuting distance, negatively on the spouse's commuting distance, and positively on the distance between workplaces. Using data for Denmark, it appears that these hypotheses hold, and that the effects of the spatial configuration are rather large.     

The Holocene Archaeology of Southwest Ethiopia: New Insights from the Kafa Archaeological Project

Abstract  

Southwest Ethiopia’s cool, moist, and steep highlands differ from other African environments, and may have fostered distinct patterns of Holocene resource use and intensification. Prior to 2004, only a few archaeological projects probed eastern and northern margins of this region. The Kafa Archaeological Project (2004–2006) excavated ten caves and rockshelters in different environments in the heart of southwest Ethiopia to obtain a Holocene chronology and compare it with adjacent regions. At Kumali Rockshelter, middle Holocene deposits show use of a microlithic industry to obtain wild game, and excellent macrobotanical preservation promises to reveal changes in plant use from 4,700 ¹⁴C bp to the present. Ceramics and domestic animals appear at Kumali and Koka by ~2,000 ¹⁴C bp, suggesting herding and pottery making appeared late and contacts with neighboring regions were tenuous. Technologically conservative people continued microlith production and sporadic rockshelter use into the eighteenth century CE.     

Spatial distribution of US employment in an urban efficiency wage setting

We analyze whether efficiency wages operate in urban labor markets, within the framework proposed by Ross and Zenou, in which shirking at work and leisure are assumed to be substitutes. We use unique data from the American Time Use Survey (ATUS) that allow us to analyze the relationships between leisure, shirking, commuting, employment, and earnings. We confirm that shirking and leisure are substitutes, and present an estimate of this relationship, representing the only empirical test of the relationship between a worker's time endowment and shirking at work. Our findings point to the existence of efficiency wages in labor markets.     

Fluvial spatial taphonomy: a new method for the study of post-depositional processes

Traditional taphonomic analyses do not consider the emergent properties resulting from the relationship of variables. Several of these emergent properties are expressed spatially. Here, we present a spatial taphonomic approach to the understanding of post-depositional processes affecting experimental assemblages modified by fluvial currents. Spatial statistical methods are a great tool to understand how different taphonomic variables relate at a spatial scale. The results of the application of this method to bone assemblages affected by low- and high-energy flows show the loss or modification of most of the original spatial taphonomic relationships. It also shows the degree of bone loss according to element, anatomical section and bone structure, and shape types. Anisotropy is identified in both experimental contexts. These results add new criteria to assess the impact of water flows in bone assemblages and contribute to define the properties of lag assemblages.     

Can MNCs promote more inclusive tourism? Apollo tour operator's sustainability work

ABSTRACT

Outbound tour operators are key actors in international mass tourism. However, their contribution to more sustainable and inclusive forms of tourism has been critically questioned. Drawing from new institutional theories in organization studies, and informed by the case of one of the largest Scandinavian tour operators, we examine the corporate social responsibility (CSR) and sustainability work in large tour operators and the challenges faced in being more inclusive. On the basis of in-depth interviews with corporate officers, document analysis and media reports, we show how top-down coercive and normative pressures, coming from the parent company and the host society shape the ability of the daughter corporation to elaborate a more inclusive agenda. However, daughter companies do not merely comply with these institutional pressures and policy is also developed from the ‘bottom-up’. We show how the tour operator's sustainability work is also the result of organizational responses including buffering, bargaining, negotiating and influencing the parent organization. By creating intra and inter-sectoral learning and collaborative industry platforms, MNCs not only exchange and diffuse more inclusive practices among the industry, but also anticipate future normative pressures such as legislation and brand risk. Daughter organizations help shape their institutional arrangements through internal collaborative platforms and by incorporating local events and societal concerns into the multinational CSR policy, especially when flexible policy frameworks operate, and the corporate CSR agenda and organizational field are under formation. However, risks do exist, in the absence of institutional pressures, of perpetuating a superficial adoption of more inclusive practices in the mass tourism industry.     

Bound by blood: the ethnic and civic nature of collective identities in the Basque Country,Catalonia and Valencia

This paper explores the factors determining collective identities in the Basque Country and Catalonia, paying special attention to language and birth as key domains of ethnolinguistic divide. We will also make a comparison to the case of Valencia, a region with a native language that nevertheless has not developed a nationalist movement. We have performed a cluster analysis to compare the differences between collective identities in these regions using data from the survey on National Identity in Spain, and discriminant analysis is used to test the validity of our model. Results show that an ethnolinguistic division, based on parental origin and linguistic skills, defines peripheral identities in the Basque Country and Catalonia, but this singularity cannot be found for Valencia. Finally, our model corroborates the relevance of ethnolinguistic factors in defining collective identities in the Basque and Catalan regions, while the civic factor may be more relevant in Valencia.
