A white pine (Pinus strobus L.) stand at the western margin of the species range, approximately 125 years of age at present, was thinned in 1953 from 33.5 m2 ha-1 to target residual basal areas of 18.4, 23.0, 27.5, and 32.1 m2 ha-1 . Repeated measurement over the following 43-years indicated that the greatest total volume production and the greatest number of large diameter trees occurred in the unit of highest residual density. Over time, the distribution of stems was predominantly random although mortality between 1979 and 1996 resulted in a tendency for clumping in the 23.0 and 27.5 m2 ha-1 treatments. DNA analysis indicated that thinning intensity had little effect on the genetic diversity of residual white pine. This study suggests that mature white pine stands in northern Minnesota may be managed at relatively high densities without loss of productivity. However, regardless of overstory density, there was little or no white pine regeneration occurring in this stand. Key words: thinning, growth, genetic diversity, molecular markers, spatial pattern, regeneration

During the 2015 refugee crisis in Europe, temporary refugee shelters arose in the Netherlands to shelter the large influx of asylum seekers. The largest shelter was located in the eastern part of the country. This shelter, where tents housed nearly 3,000 asylum seekers, was managed with a firm top-down approach. However, many residents of the shelter—mainly Syrians and Eritreans—developed horizontal relations with the local receiving society, using social media to establish contact and exchange services and goods. This case study shows how various types of crisis communication played a role and how the different worlds came together. Connectivity is discussed in relation to inclusion, based on resilient (non-)humanitarian approaches that link society with social media. Moreover, we argue that the refugee crisis can be better understood by looking through the lens of connectivity, practices, and migration infrastructure instead of focusing only on state policies.

Stakeholders play vital roles in the implementation of sustainable last mile logistics solutions. Therefore, the first step in setting up successful sustainable last mile logistics is to conduct stakeholder analysis. This paper analyzes the goals of the stakeholders in the Heijendaal living lab, a city logistics project that uses two hubs for bundling goods to be delivered to the Heijendaal campus in The Netherlands. We use the Theory of Planned Behavior and Policy Deployment to present a qualitative case study, which examines the goals of stakeholders in relation to their roles in the supply chain and in the organization, and if these goals lead to their expected participation behavior. Results show that stakeholders have economic, social, and environmental goals and that some of these goals are prominent within certain groups of stakeholders along the supply chain and within the organization. In addition, the set goals do not always lead to participation behavior of stakeholders due to identified disruptions and habits. This study identifies the importance of information sharing and collaboration within the supply chain, the leading role of middle-level managers in translating strategic to operational goals, and the stimulation of behavioral factors to increase participation of stakeholders in the living lab.

This article probes the extent to which literary history and cultural history may mutuallyilluminate each other, without neglecting the poetic dimension of literary works. Thispoetic dimension is embedded within the genre repertoires that shape the production andreception of literary works. One should therefore take into close account that the literaryrepresentation of social conflict is always deflected by the prism of genre conventions.Focusing on the case study of the Dutch Gothic novel, I argue that Gothic tales provide aspecific take on the post-war modernization of the Netherlands. As such, they make avaluable contribution to historical debates about the periodization of the sixties andseventies, not in spite of, but because of their specific poetic properties. Thus, it is verywell possible to bring literary works to bear upon the discussion of historical issueswithout either infringing upon the relative autonomy of the literary system or neglectingthe specific expertise of literary studies as a discipline in its own rights.
