Residential location,workplace location and car driving in four Norwegian cities

Based on a study in four Norwegian cities (Oslo, Stavanger/Sandnes, Bergen and Trondheim) differing in size and centre structure, this article illuminates how residential and workplace location, local-area density and transit accessibility influence different aspects of travel behaviour. We find strong effects of residential and workplace distance to the city centre on overall driving distances and commuting distances. We also find clear effects of local area densities around residences and workplaces on the choice of car as a travel mode, along with less pronounced effects of the distance from dwellings and workplaces to the city centre. In the cities with the best developed transit provision, we also see clear effects of transit accessibility at the residence on the propensity of choosing the car as travel mode. The results provide strong support of Norwegian national policies of urban densification as a planning strategy to curb the growth in urban motoring. However, although the influences of urban structure on travel show many similarities across the four cities, there are also important differences reflecting variations in centre structure (predominantly mono- or polycentric) and population size. The magnitude of the influences of various urban structural characteristics on travel behaviour are thus highly context-dependent.     

Anti-Ballistic Missiles and the Liberal–Conservative Internationalist Divide in Cold War Canada, 1966–1970

Shortly following Canada's controversial adoption of nuclear weapon roles in NORAD and NATO in 1963, the focus of nuclear debates shifted to the potential impact on Canadian and international security of the construction of US anti-ballistic missile (ABM) systems. This article expands the focus of scholarship on the ABM issue from the political and policy-making settings to include members of the attentive elite and the news media, and finds these groups deeply divided between liberal and conservative internationalists. On the one hand, supporters of liberal internationalism believed that AMB systems would destabilise the international security environment and ultimately increase the likelihood of nuclear war. Conservative internationalists took the opposite position, arguing that the systems represented a necessary addition to the Western nuclear deterrent and would make nuclear war less likely. In other words, the ABM debate exposed deep divisions in Canadian society between those who preferred diplomatic and multilateral versus military means of achieving middle power goals in the international system.     

1. ACTS OF GOD? MIRACLES AND SCIENTIFIC EXPLANATION1

God, at least as an active agent, is excluded from today's scientific worldview—including the worldview of the humanities. This creates a gulf between a godless science and believers in God's active presence in the world, a gulf that I argue is unbridgeable. I discuss the general methodological question from the starting point of a 1652 episode in a Norwegian valley, where God reportedly saved two brothers stranded on an islet by providing just enough fresh, edible plants each day for them to survive until they were found by a search team after twelve days. I resist four temptations to take easy ways out of a real dilemma: whether to accept or dismiss this and similar miracle accounts. The first is to explain evidence and refuse to consider the events about which the evidence reports; the second, to deny that reports of miracles represent a problem since biblical actors and authors lacked Hume's concept of inviolable laws of nature; the third, to become resigned to a putative epistemological gap that renders impossible any dialogue on religion with actors from the early modern period; the fourth, to restrict our studies to asking what the events meant to the historical actors without passing judgment on the truth value of their beliefs. I suggest that when doing historical research, historians are part of a scientific community; consequently, historiographical explanations must be compatible with accepted scientific beliefs. Whereas many historians and natural scientists in private believe in supernatural entities, qua professional members of the scientific community they must subscribe to metaphysical naturalism, which is a basic working hypothesis in the empirical quest of science. As long as the supernatural realm is excluded from the scientific worldview, however, historians’ explanations of miracles will differ fundamentally from the explanations proffered by believers.     

Structure and Strategy for Regional Learning and Innovation--Challenges for Regional Planning

Development of codified and tacit knowledge is important for capacity building in regional communities. To do so regions need active cooperation and trust building between public organizations related to research and education, private companies and organizations and the civil society so as to cross sector barriers and to mobilize to meet regional challenges proactively. Such processes must enjoy wide support in the regional community; mobilization for change must take place from below and across a broad front. Actors from outside can stimulate such processes, but they cannot take responsibility for them. The role in building out the community that is held by democratically elected bodies, make it natural to demand or expect that such actors take an initiative towards improvement, which brings challenges that are discussed later in this article.     

Fracture spacing during hydro‐fracturing of cap‐rocks

Layered low permeability rock units, like shales, represent seals or ‘cap‐rocks’ in a variety of geological settings. A continuous increase in the fluid pressure gradients across a virtually impermeable rock layer will ultimately lead to hydro‐fracturing. Depending on the boundary conditions, such fracturing may lead to the formation of a set of sub‐parallel cracks oriented more or less perpendicular to the cap‐rock layer. In this article, we propose a new numerical model that describes interactions between multiple cross‐cutting fractures in an elastic low permeability rock layer. The width of each fracture and the spacing between them are modeled as a force balance between the fluid pressure and the elastic forces in the cap‐rock and between each fracture. The model indicates that the system of fractures evolves toward a spatially periodic steady‐state distribution with a fixed fracture spacing and aperture. The results are similar for incompressible and compressible fluids. The steady‐state conditions depend on only two dimensionless parameters, and the fracture spacing is only weakly dependent on the cap‐rock thickness. This is in contrast to fracturing produced by simple extension of an elastic rock layer beyond the fracture strength, in which case fracture spacing is proportional to layer thickness.     

Material culture after text: re‐membering things

Bronze Age finds in Norway have recurringly generated discussion throughout 150 years of Norwegian archaeology. This article outlines the history of attitudes towards the Bronze Age in Norway, and attempts to identify paradigmatic features. In general, the same basic analytic concepts have been employed since Christie's and Worsaae's days until the present. This is somewhat surprising, especially in light of general archaeological postwar research efforts in Norway and international developments in theory and method. The article examines some of the contemporary social mechanisms that have hampered rejuvenation of Bronze Age research, and outlines basic positions the author believes to be valuable.     

“Brain Drain” or “Brain Gain”? Students’ Loyalty to their Student Town: Field Evidence from Norway

In the global economy regions fight a two-front “war” to attract young people. On the one hand, they compete against more urban areas because young people leave home to study and do not return to their home region (“brain drain”). On the other hand, they struggle to attract new residents, students and entrepreneurs to their local region (“brain gain”). The context is a student town of a strong industrial region characterized by a net export of young people and an increasing demand for highly qualified labour. The purpose is to gain insight into how student loyalty to a student town may be enhanced. A partial least square path modelling approach is used to estimate a structural equation model of student town loyalty. One finding is that the creation of student town satisfaction has more influence on student town loyalty than reputation building. “Social activity” is the most important loyalty driver. This antecedent is mediated through student town satisfaction and reputation, as well as university college reputation. The town municipalities and the university college should thus be coordinated in their effort to increase student town loyalty to bring down the “brain drain” and increase the “brain gain” in the region.     

Gone to smelt iron in Courland: technology transfer in the development of an early modern industry

SUMMARY: In the Duchy of Courland and Semigallia, corresponding to the southern and western parts of present-day Latvia, an iron industry based on blast-furnace technology, mainly using local bog iron ore, existed in the 17th and 18th centuries. Transfer of knowledge and skill through the recruitment of specialists from other countries of Europe was crucial to the development of this industry; technology was also re-exported to Russia and elsewhere. Recent archaeological and archaeometallurgical investigations supplement the written evidence, highlighting the specific local conditions that influenced the development of ferrous metalworking here in the early modern period.
