    The Keene Forest: A Preliminary Report

    In 1913 the Yale School of Forestry came into possession of certain parcels of land located near Keene, New Hampshire. This land amounting to 629.4 acres was presented to the School as a nucleus for a school forest to be used for purposes of instruction and research. Subsequently in March, 1915, additional lots comprising 270.9 acres were purchased with funds contributed by the original donor. The present area totals 900.3 acres and is know as the Keene Forest

    Nursery Investigations with Special Reference to Damping-off

    The object of this investigation is therefore fourfold: 1. To determine an effective means of control of damping-off in the School of Forestry Nursery. 2. To determine the effects of different soil sanitation agents on the germination and later growth of coniferous stock. 3. To determine the effects of different sanitation agents on the germination and growth of weeds. 4. To determine the effects of different sanitation agents on the physical characteristics of the soil

    Some Effects of Cover over Coniferous Seedbeds in Southern New England

    The object of the study as at first conceived was to secure experimental data under the climatic conditions of southern Connecticut: 1. On the effect of shade as compared with full light on the time required for germination, and on germination values in representative conifers, and on survival and growth during the first season. 2. On the effect of mulch as compared with exposed soil on the time required for germination, and on germination values in representative conifers, and on survival and growth during the first season

    Do new Ethical Issues Arise at Each Stage of Nanotechnological Development?

    The literature concerning ethical issues associated with nanotechnologies has become prolific. However, it has been claimed that ethical problems are only at stake with rather sophisticated nanotechnologies such as active nanostructures, integrated nanosystems and heterogeneous molecular nanosystems, whereas more basic nanotechnologies such as passive nanostructures mainly pose technical difficulties. In this paper I argue that fundamental ethical issues are already at stake with this more basic kind of nanotechnologies and that ethics impacts every kind of nanotechnologies, already from the simplest kind of engineered nanoproducts. These ethical issues are mainly associated with the social desirability of nanotechnologies, with the difficulties to define nanotechnologies properly, with the important uncertainties surrounding nanotechnologies, with the threat of ‘nano-divide’, and with nanotechnology as ‘dual-use technology’

    Trust in Nanotechnology? On Trust as Analytical Tool in Social Research on Emerging Technologies

    Trust has become an important aspect of evaluating the relationship between lay public and technology implementation. Experiences have shown that a focus on trust provides a richer understanding of reasons for backlashes of technology in society than a mere focus of public understanding of risks and science communication. Therefore, trust is also widely used as a key concept for understanding and predicting trust or distrust in emerging technologies. But whereas trust broadens the scope for understanding established technologies with well-defined questions and controversies, it easily fails to do so with emerging technologies, where there are no shared questions, a lack of public familiarity with the technology in question, and a restricted understanding amongst social researchers as to where distrust is likely to arise and how and under which form the technology will actually be implemented. Rather contrary, ‘trust’ might sometimes even direct social research into fixed structures that makes it even more difficult for social research to provide socially robust knowledge. This article therefore suggests that if trust is to maintain its important role in evaluating emerging technologies, the approach has to be widened and initially focus not on people’s motivations for trust, but rather the object of trust it self, as to predicting how and where distrust might appear, how the object is established as an object of trust, and how it is established in relation with the public
