In 1714, the Dutch scholar Willem Jacob's Gravesande published a theoretical essay on how to optimize the air-pump. Although his paper did not attract much attention, there was one important supplier of air-pumps who knew about it: the Leiden instrument maker Jan van Musschenbroek. 's Gravesande and he cooperated intensively between 1717 and 1742. Among other things, this cooperation resulted in two new air-pump designs to replace Musschenbroek's own models. A closer analysis of's Gravesande's influence on Musschenbroek's repertoire reveals that (...) the various changes were not inspired by the theory of the air-pump. Commercial and practical considerations were much more important than theoretical reflections, even though both approaches aimed at the same goal: a fast and handy air-pump. (shrink)

in 1612, lodovico cigoli completed a fresco in the pauline chapel of the basilica of santa maria maggiore in rome depicting apocalypse 12: “a woman clothed with the sun, and the moon under her feet.” he showed the crescent moon with spots, as his friend galileo had observed with the newly invented telescope. considerations of the orthodox view of the perfect moon as held by philosophers have led historians to ask why this clearly imperfect moon in a religious painting raised (...) no eyebrows. we argue that when considered in the context of biblical interpretation and the rhetoric of the counter-reformation, the imperfect moon under the woman's feet was entirely consistent with traditional interpretations of apocalypse 12.

Ever since they began to take an interest in lens grinding, the brothers Christiaan and Constantijn Huygens searched for high-quality glass to turn in to lenses. Historical research in combination with optical measurements on preserved lenses has allowed the verificationof the lenses ground by the brothers, and also provided information on who helped them with the necessary knowledge and material.

United Nations (UN) leaders suggest that the world is not on track to meet the Sustainable Development Goals (SDGs) by 2030. The purpose of this paper is to explore whether the SDGs provide a valuable platform to call for a basic income (BI) globally. Adopting a critical historical studies approach, the article traces the evolution of ‘development’, including the UN decades of development, the Millennium Development Goals, and the SDGs. It subsequently describes the structural adjustment and poverty reduction efforts by (...) the World Bank and International Monetary Fund, and then outlines why the SDG framework may be helpful in advancing a BI. We argue that as climate-related disasters increase, a BI will be vital in providing a modicum of security in an increasingly unstable world. Calls for BI must be anchored to a broader change agenda that recognizes the causes of poverty and income inequality, and seeks their dismantling and redress. (shrink)

Recent policy developments in the area of livestock husbandry have suggested that, from the perspective of optimizing animal welfare, new animal husbandry systems should be developed that provide opportunities for livestock animals to be raised in environments where they are permitted to engage in “natural behavior.” It is not known whether consumers regard animal husbandry issues as important, and whether they differentiate between animal husbandry and other animal welfare issues. The responsibility for the development of such systems is allocated jointly (...) between farmers, regulators, different actors in the food chain, and consumers. This research focuses on understanding consumer attitudes and preferences regarding the development and introduction of such systems, to ensure that they are acceptable to consumers as well as producers, regulators, and scientists. Consumer perceptions of animal welfare and animal husbandry practices were evaluated using quantitative consumer survey, which focused on two animal husbandry issues – farmed pigs and farmed fish. Following pilot work, 1000 representative Dutch consumers were sampled about their attitudes to either pig or fish husbandry. The results indicated that consumers think about animal welfare in terms of two broad categories related to their health and living environment, but do not think about welfare issues at a more detailed level. Greater concern was expressed about the welfare of pigs compared to fish. Consumer trust in labeling also emerged as an important issue, since consumers need to trust different food chain actors with responsibility for promoting animal welfare, and are reluctant to consider the details of animal husbandry systems. As a consequence, a transparent, enforceable, and traceable monitoring system for animal welfare friendly products is likely to be important for consumers. (shrink)
