Life-cycle service was an essential institution in early-modern England that slowly died during the transition from a pre-industrial to a fully industrial economy. A socially pervasive and culturally broad movement of young people from their parental homes to live and serve in the homes of others, life-cycle service was integral to the demographic, economic, and social framework of the era and could not survive when that framework changed. This article examines the institution of life-cycle service, some of the underlying demographic, economic, and social structure that supported it, the changes in that structure that led to its demise, and the ramifications for young people of that demise. Although inevitable, the loss of life-cycle service with its broad social base denigrated service as an institution and was not without other costs especially for young women. 相似文献

Single fibers less than 1 mm long of nine types of acrylic fibers were thermally shrunk from 85°C to 285°C by hot stage optical microscopy. A surprisingly wide variety of behavior was observed. The temperature for the onset of shrinkage ranged from 105°C to 190°C; total contraction ranged from 2% to 64%; and some fibers contracted rather steadily, whereas others contracted abruptly. Reproducibility of shrinkage was excellent for most monocomponent fibers but was less reproducible for bicomponent fibers. In general, it was found that the technique may be used to discriminate among fiber types within a single fiber generic class using submicrogram sized samples. 相似文献

Bullet embolism is a well-recognized phenomenon. While bullet embolism is not common, renal artery bullet embolism appears to be very rare. We report three cases of bullet embolism to a renal artery. Autopsy findings and bullet types are presented. Such cases are of particular interest to both the medical examiner and the clinician. Failure to consider this phenomenon clinically could lead to infarction of a kidney. A consideration of this phenomenon at autopsy could shorten the dissection time required to retrieve the bullet. 相似文献

Systems approaches possess an ability to deal with large numbers of interacting variables and relations. They are here connected tocitizen information systems (distinguished frommanagement information systems) and to mixed, adaptive, conditional models for urban planning. The latter permit flexible and continuing responses to dynamically changing urban conditions, including citizen attitudes and reactions, as well as to changing economics and technologies. These models are mixed in that they allow actions and reactions from a multiplicity of decisionmakers. The resulting decisions are made only conditionally, rather than once-and-for-all, on a comprehensive basis as in the customary master city plan. Proceeding in this conditional manner, the model then permits adaptation to changing values and objectives as, at each stage, it makes the systems consequences apparent.The systems approach is related to a host of important methodological developments in mathematics, statistics, etc., as well as in electronic computers and their use. These distinguish modern systems approaches from predecessors like the holism of Jan Christiaan Smuts and others in pre-war science. The mixed, conditional, adaptive models suggested here are compared with other approaches like advocacy planning, the comprehensive master city plan and ad hoc planning. It is found to be possible at least in principle, to accommodate all of these and even to extend matters further to include day-to-day as well as longer range facilities plans in the indicated systems approach by virtue of the improved methodologies that may now be used or developed for these purposes.This paper was prepared for presentation before the Division 1 (General), American Psychological Association Meetings in Miami Beach, Florida on September 5, 1970.Also, Joint Urban Sciences Information Institute, Research Report No. 5. 相似文献

This essay was adapted from a speech presented by the author on February 12, 2008 at a Colloquium entitled “What's Best for Children? How Judges Use Neuroscience to Break the Cycle of Child Maltreatment.” The colloquium was sponsored by the Harvard Center on the Developing Child and held at Harvard Law School. It focuses on the wealth of knowledge that has been discovered about infant and child development and the importance of incorporating that knowledge into judicial decision making in child maltreatment cases. 相似文献

This article reports on empirical research undertaken to test the claim made in a law reform project that citizens could be made more certain of their legal obligations by changing the legal paradigm used to express their rights and obligations. Our research tested a number of hypotheses involving different formulations of the claim being made. We find that the alternative paradigm being presented was inferior to current practice and offer some reasons that would explain our results and the significance of this work for other areas of legal research. 相似文献

The mass media devote a great deal of attention to high‐profile elections, but in American political life such elections are the exception, not the rule. The majority of electoral contests feature candidates who are relative unknowns. In such situations, does name recognition breed contempt, indifference, or affection? Existing work presents modest theory and mixed evidence. Using three laboratory experiments, we provide conclusive evidence that name recognition can affect candidate support, and we offer strong evidence that a key mechanism underlying this relationship is inferences about candidate viability. We further show that the name‐recognition effect dissipates in the face of a more germane cue, incumbency. We conclude with a field study that demonstrates the robustness of the name‐recognition effect to a real‐world political context, that of yard signs and a county election. 相似文献
