Selectivity in exposure to information.

2 hypotheses, derived from Festinger's theory of cognitive differences were tested: following a decision, persons tend to seek information that favors the chosen alternative and to avoid information that favors the rejected alternative; and the more important the decision, the greater is the subsequent selectivity in exposure to information. The method involved eliciting attitudes from college students as to various conditions regarding examination procedures. The hypotheses were supported.

Decision making,computer attitudes and expert systems: What is our direction?

Expert systems have been concerned with applications dealing with medical diagnosis, mineral exploration, and computer configuration, with some efforts relatively successful in achieving results at least as good as human experts. Today, much is being written about these systems and managerial decision-making activities in organizations and the positive impact that they can have in these situations. However, it appears that expert systems could become somewhat of a panacea for some organizational ailments as research, development, and marketing of them continues at a fast pace. What may be forgotten in this technological thrust is the individual decision maker and his/her unique style of decision making which could affect acceptance and use of these systems. Another important consideration is the attitude people have toward computers and computer systems, which along with decision-making styles could certainly affect expert system effectiveness and ultimate success in organizations. This paper provides a discussion of potential problems that could occur regarding individual decision making and attitudes and their relationships to these systems.     

一种带参数的区间粗糙数型多属性决策方法

针对带参数的区间粗糙数型多属性决策问题,首先定义了带参数的区间粗糙数的期望和方差,以期望值和方差集结函数的优劣度得到正负理想点,然后提出了一种积分形式的带参数型的区间粗糙数新的相离度,并根据已有的加权区间粗糙的距离平均算子（WIRDAA）概念,构建含参数的区间粗糙数型MADM的熵值法模型得到最终排序,最后以一个实例说明该方法的可行性。
