A multi-objective mathematical programming problem with fuzzy relation constraints

In this study we discuss the problem of multi-objective mathematical programming with constraints defined by ‘max-min’ composite fuzzy relation equations. Since the feasible region is normally non-convex, the properties of the efficient points of a non-convex feasible region under multi-objectives are investigated and illustrated by examples. The necessary and sufficient conditions are proposed and proved. To facilitate decisions, a procedure that transforms these efficient points of an interval-valued decision space into a constant-valued decision space is proposed when the level of confidence is given by a decision maker. Then the transformed problem becomes a multi-attribute decision problem that can be evaluated by Yager's method to find the optimal alternative.     

从认识论看创面敷料的演变与进步

辩证唯物主义的认识论认为,人类认识的一般秩序是：“个性——共性——个性”。认识的发展要经过“实践、认识、再实践、再认识”的循环往复、以至无穷的过程。纵观创面敷料的演变及进展,完全遵循和验证了这一真理。     

Effects of serial versus concurrent task sequencing an acquisition, maintenance, and generalization

Effects of serial and concurrent task presentation on skill acquisition, generalization, and maintenance were compared. Two severely retarded females participated. During serial training, items of one response class, tracing, were trained to mastery before those of a second task, vocal imitation. In the concurrent method, training on two different tasks, tracing and vocal imitation, alternated within sessions for fixed periods of time. There were no major differences between the serial and concurrent methods of instruction in the number of steps attained per behavior or in the number of trials required to reach criterion levels of performance. It was found however, that concurrent training resulted in more generalization. Retention results were not consistently related to training method.     

21世纪医生培养目标研究的主要内容及实现措施

为了重新设计21世纪的医生,世界各国都把研究和制订21世纪医生的培养目标作为医学教育改革的重大研究课题。培养目标研究的主要内容包括明确培养目标的总体要求、强调医生能力的培养以及体现医生的综合角色等。为了保障21世纪医生培养目标的顺利实现,采取了立法、试点及课程的全面改革措施。作者还针对我国情况提出了修订我国培养目标的几点建议。     

Fitness of Job Type and Management by Objectives: Mediating Effects of Perception of Effectiveness and Goal Commitment and Moderating Effects of Supervisor's Behavior

Abstract : This study investigated the influence of job type (line or staff) on perceptions of management‐by‐objectives (MBO) effectiveness, goal commitment, and goal‐attainment behavior, as well as mediating effects of perceptions of MBO effectiveness and goal commitment and moderating effects of supervisor behavior. Participants were 152 employees of a factory that manufactures drugs for a Japanese pharmaceutical company. The primary duties of line personnel involved production. The duties of staff personnel who supported production included supplying materials and production planning. Results indicated that line personnel perceived MBO as a more effective system for improving individual performance and showed higher goal commitment and more active behavior related to goals than staff personnel. Although perception of MBO effectiveness was related to goal commitment, it had no mediating effect. Goal commitment mediated between job type and goal‐attainment behavior. Supervisors’ goal‐setting behavior had different positive effects on goal commitment and goal‐attainment behavior for those in line and staff positions. MBO was a better fit for line positions than staff positions. However, supervisor behavior increased goal‐attainment behavior in staff positions. The results indicated that it is important for supervisors in a business organization to operate a management system flexibly.     

SCIENCE‐AND‐RELIGION/SPIRITUALITY/THEOLOGY DIALOGUE: WHAT FOR AND BY WHOM?

In recent years the science‐and‐religion/spirituality/theology dialogue has flourished, but the impact on the minds of the general public, on society as a whole, has been less impressive. Also, religious believers and outspoken atheists face each other without progressing toward a common understanding. The view taken here is that achieving a more marked impact of the dialogue would be beneficial for a peaceful survival of humanity. I aim to argue the why and how of that task by analyzing three possible purposes of the dialogue and their logical interdependence, suggest conceivable improvements of the quality and extent of the current efforts toward a negotiated action plan, and consider an enlargement of the circle of the actors involved. The dialogue that has been carried on between science and religion/spirituality/theology could be expanded and usefully applied to some major problems in the present world.     

烧伤换药时使用度冷丁有关问题的思考

对于烧伤换药伴随的操作痛,医生应积极地预防和处理。使用度冷丁控制操作痛有效且合理。度冷丁依赖的问题不容忽视,但重视度冷丁的依赖性并不意味着抵制度冷丁科学、规范地使用。烧伤换药前使用度冷丁的镇痛效果好于烧伤换药中患者出现剧痛后使用度冷丁的镇痛效果。     

The challenge of “Healthy People 2000”

The federal Office of Disease Prevention and Health Promotion (U.S. Public Health Service) has again prepared a compilation of goals and objectives for the health of the Nation's people, applicable to anticipated achievements within the decade ending in the year 2000. This effort involved work groups from numerous federal agencies, testimony in regional hearings from 800 citizens, and enrollment of a consortium of 300 national organizations. The final product, Healthy People 2000, was released in September 1990, and contains 298 measurable objectives. Content regarding children, genetic disorders, developmental disabilities, and disabilities in general is less featured and less specific than was hoped for. Ten objectives of relatively direct concern to geneticists are discussed, plus 23 others of interest in the maternal and child health field. On balance, it is suggested that the Healthy People 2000 objectives can be useful and stimulating for workers in genetics, child health care, and disabilities' services. Regrettably, there was no simultaneous proposal of legislation that would provide new federal programs, funding, or assistance to states.     

Gleaning in the field of dual scaling

Some historical background and preliminary technical information are first presented, and then a number of hidden, but important, methodological aspects of dual scaling are illustrated and discussed: normed versus projected weights, the amount of information accounted for by each solution, a perfect solution to the problem of multidimensional unfolding, multidimensional quantification space, graphical display, number-of-option problems, option standardization versus item standardization, and asymmetry of symmetric (dual) scaling. Contrary to the common perception that dual scaling and similar quantification methods are now mathematically transparent, the present study demonstrates how much more needs to be clarified for routine use of the method to arrive at valid conclusions. Data analysis must be carried out in such a way that common sense, intuition and sound logic will prevail.Presidential Address delivered at the Annual Meeting of the Psychometric Society, Banff Centre for Conferences, Banff, Alberta, Canada, June 27–30, 1996.
