The University Circle Development Foundation (UCDF) was created in 1957 to implement a master plan for the development of Cleveland's University Circle district. Run by the presidents of three major institutions, UCDF was successful in coordinating land use and construction projects in its early years. However, its elite authority structure proved insular and inflexible when dealing with students, faculty, and adjacent neighborhoods, and it was dissolved in 1970.  相似文献

In this paper we extend the ELSP model to allow for linearly changing demand rates over a fixed planning horizon. This extension of the ELSP research provides a model that can be used in coordinating the production and marketing planning activities in a firm. The model allows the user to evaluate the impact of changes in product demand on production costs and customer service. We solve the model using a standard nonlinear programming package (MINOS) and show through examples based on actual production data how the model can be used to support coordinated production and marketing planning.  相似文献

Maturation of tactile sensitivity prior to term was examined in 36 preterm and 13 full‐term infants using a fixed‐trial, habituation procedure. Each infant was presented with a series of 8 habituation (arm stroke), 2 novel (arm lift), and 2 recovery (arm stroke) stimulus trials while heart rate and body movements were recorded. Maturation was observed with a gradual increase in the magnitude of the stimulus‐elicited cardiac acceleration and cardiac‐movement coupling from 30 to 40 weeks postconceptional age. The majority of infants displayed habituation—an excitatory response (heart rate acceleration and body movement)—to the initial presentation of a tactile stimulus, response decline with repeated stimulations, and renewed response to a novel stimulus. A substantial number of infants (40%) failed to respond initially to the tactile stimulus, increased responding over several stimulus presentations, and failed to discriminate the presentation of a novel stimulus. We speculate that these differences in response patterns observed over all ages represent individual difference in the perception of stimulus intensity.  相似文献

Although order and labor dispatching in the job shop manufacturing setting have been investigated extensively over the last three decades, its representation of actual processes found in practice today is limited due to the move to cellular manufacturing (CM). Manufacturing cells have become an important approach to batch manufacturing in the last two decades, and their layout structure provides a dominant flow structure for the part routings. The flow shop nature of manufacturing cells adds a simplifying structure to the problem of planning worker assignments and order releases, which makes it more amenable to the use of optimization techniques. In this paper we exploit this characteristic and present two mathematical modeling approaches for making order dispatching and labor assignment/reassignment decisions in two different CM settings. The two formulations are evaluated in a dynamic simulation setting and compared to a heuristic procedure using tardiness as the primary performance measure. The formulations are superior to the heuristic approach and can be incorporated into detail scheduling systems that are being implemented by corporations employing enterprise resource planning (ERP) systems today.  相似文献

Over the last 25 years, the seemingly simple still‐face phenomenon has elicited a tremendous amount of empirical and theoretical work. Adamson and Frick (2003/this issue) provide a comprehensive review and in‐depth analysis of this large body of research. In our commentary, we focus on 3 major points. First, we described several methods to define operationally the still‐face effect. Second, we noted the important role of adult touch in the still‐face procedure, and that the effect can be reproduced without adult touch, by live, televised and “virtual” adult faces–‐making it a true “still‐face” effect. Third, we emphasized a major methodological strength of the still‐face procedure: the use of multiple response measures. By measuring both infant visual attention and affect responses, adaptations of the still‐face procedure provide infant researchers with a powerful general method for studying the development of infant social competence.  相似文献

Abstract

Evaluations of therapeutic processes and outcomes by clients, therapists, and independent third parties are all important dimensions in an overall system of accountability for a college mental health facility. This study focused on client evaluation. All clients (N = 287) who used mental health services in a large midwestern university during a two-week period completed an evaluative questionnaire. In contrast to previous satisfaction studies that focused on overall satisfaction, this study examined specific therapist and client tasks and their relationship to outcomes. The findings indicate that different types of client evaluation items yield somewhat different results. Those specific evaluation items have varying relationships with overall measures of client satisfaction and problem improvement. The study also pointed to the importance of looking at sex differences in client evaluations of therapy and at differences among therapists in their relative success in working with clients with differing problems.

“The Diagnosis of Testicular Torsion,” Bruce E. Haynes, Howard A. Bessen, and Vital E. Haynes. Prompt diagnosis of testicular torsion remains difficult. Since warning symptoms occur in one third of patients and salvage rates correspond to the interval between symptom onset and operation, higher salvage rates should be achievable. Separating torsion from epididymitis is complicated by overlapping ages of peak incidence, shared symptoms, and the need for rapid distinction of the two. Doppler studies (88% accuracy) and nuclear scans (95% accuracy) help confirm the diagnosis, but correct technique is essential, and their use should not delay prompt operation. The diagnosis of epididymitis should be made cautiously in persons younger than the age of 35 years. (Journal of the American Medical Association 1983;249:2522–2527.)

“Hepatitis and Jaundice Associated with Measles in Young Adults: An Analysis of 65 Cases,” Dov Gavish, Yosef Kleinman, Abraham Morag, Tova Chajek-Shaul. We analyzed the clinical course of 65 adult patients hospitalized because of measles during the years 1975 and 1981–1982. Liver involvement was found in 80% (52/65) of the patients, five patients had clinical jaundice. The disturbances of liver function tests reached their peak values between days 5 and 10 of the disease. In this study of measles in adulthood we have three observations of unusual interest: (1) hepatitis occurs commonly in the more severely ill patients and it may manifest clinically as jaundice; (2) long-term follow-up (up to seven years) shows a clear tendency to complete resolution of the liver damage; (3) there is a clear correlation between the severity of hepatic involvement and the occurrence of secondary bacterial infections.

Equipment failures can have significant implications in terms of cost and customer satisfaction. Reducing the time required to find the cause of a failure can provide large cost savings and help preserve customer goodwill. Single‐item discrete sequential search models can be used to sequence the tasks in diagnostic search to minimize the expected time required to find the cause of the failure. We increase the utility of the single‐item discrete sequential search model by developing a formulation that includes simple precedence relationships as well as sequence dependent relationships defined by group activities. This formulation can be applied to a number of other problems including determining the sequence for multiple quality control tests on an item, scheduling oil well workovers to maximize the expected increase in oil production, and sequencing tasks in a research project where there is a technological risk associated with each task.  相似文献

This article advances the “doing gender” framework by highlighting some unique interactive challenges that nonbinary individuals encounter within the binary gender system. In order to access testimony about these experiences from a large group of people, this study turns to a genderqueer community on the social media site Reddit. Discourse analysis of discussion threads and content analysis of selfies reveal various symbolic mechanisms through which nonbinary people do, redo, and undo gender. These findings illuminate a range of strategies that people utilize to negotiate gender attribution within the gender binary system.
