Abstract In this article, the author presents a strategy for designing relational databases with the program FileMaker Pro (FileMaker) to study the histories of individuals and organizations. The approach facilitates efficiency in inputting data and flexibility for constructing statistical analyses from the raw data. The key feature of the strategy is to define the basic unit of observation in the database in terms of an agent, an event, and a date. Given that programs such as FileMaker can easily sort data by agent and date, once one structures the data correctly, he or she can construct well-ordered event histories for agents, even if the researcher enters the data in an unordered fashion. By using events that happened to an agent at a particular time as the basic unit of observation, one maintains maximum flexibility to do statistical analysis that aggregates basic data in different ways. This article illustrates the power of the approach by outlining ways to analyze changes in geographic distances between two events marking the life histories of chemists. 相似文献

The distributional differentiation of Baltoscandian Middle Ordovician shelly faunas in terms of confacies belts has a counterpart in the southern and central Appalachians, where three belts, parallel to the mountain chain, are distinguished: the Blount, Tazewell and Lee Confacies Belts. As in Baltoscandia, the boundaries between these belts are sharp. The Blount Belt high-diversity shelly macrofauna is closely similar to Scoto-Appalachian faunas of northeastern Ireland and southwestern Scotland (Girvan). The Lee Belt fauna is virtually the same as that of the North American Midcontinent, and that of the Tazewell Belt is transitional between those of the Blount and Lee Belts. The ecological factors causing the confacies differentiation are currently not clearly understood but the differentiation was evidently not due to a single factor such as water depth, although this factor was apparently important for second-order differentiation (biofacies) within a confacies belt. The spatial differentiation patterns of the shelly, graptolite, and conodont faunas do not always coincide, suggesting that the factors controlling the distribution were largely specific for each fauna. 相似文献

This article calls for a new analytical approach to address how the emergence of a new European spatial policy field conditions policy‐making and implementation across Europe. This is now urgent because as the new policy field takes shape, its core ideas and values are being contested across different scales, sectors and territories of governance, creating new debates and arenas where understandings of space, place and connectivity, and relations between environment, society and economy, are being recast in a European light. In the full flow of generating a new policy field, we still seem to know little about what is being put at stake, or specifically how this is occurring. A value‐driven critical response from the research community is therefore needed, informed by research activity reaching across many dimensions of governance and policy‐making. The point of developing such an approach is not to discount previous research, but to explore how to generate synthetic and critical insights from different disciplinary and conceptual approaches within an integrated analytical framework. After this discussion, we conclude by proposing that IMAGES (Integrated Multi‐level Analysis of the Governance of European Space) can provide such a framework for analysing the emerging policy field of European spatial polices by constructing narratives of how spatial policy ideas and concepts turn into programming space, and how different territories interrelate with these policy concepts, and at the same time contribute to shaping them. This viewpoint and framework are predicated on the authors' belief that values behind the concepts remain hidden at present, both in policy processes and related research. Spatial policies seem to happen in a vacuum of values. By putting spatial justice as a value into this vacuum and by exploring the multi‐level governance of European space within an integrative analytical framework, the further development and application of the IMAGES framework can fulfil the need to contest the idea of objective policy‐making and analysis in European spatial policy. 相似文献

This article discusses the works of the first two lecturers on natural law in Copenhagen, Henrik Weghorst and Christian Reitzer. Contrary to the existing scholarship which characterises their works as derivative of either Grotius or Pufendorf, the article argues that the character and significance of these works can only be grasped when understood in light of the local intellectual traditions which they built upon. Seen against this background, it becomes clear that Weghorst and Reitzer developed significantly different theories of natural law, disagreeing on such fundamental issues as the definition of law, the moral good, and the role of sociality in natural law. Following a tradition of Christian natural law in Kiel, Weghorst developed a theory of natural law fundamentally critical of the secularising theories of Grotius and Pufendorf, while Reitzer followed Pufendorf and his disciple Christian Thomasius in Halle. The article concludes by indicating how Weghorst’s and Reitzer’s works established the framework for discussions of natural law in the first decades of the eighteenth century, suggesting the need for further research into the significance of natural law for the early enlightenment in Denmark–Norway. 相似文献
