Summary  Evolution is a time process. It proceeds in steps of definite length. The probability of each step is relatively high, so self organization of complex systems will be possible in finite time. Prerequisite for such a process is a selection rule, which certainly exists in evolution. Therefore, it would be wrong to calculate the probability of the formation of a complex system solely on the basis of the number of its components and as a momentary event.  相似文献

Adaptation to field displacement during head movements in the direction with the head rotation and in the direction against it was produced under otherwise identical conditions and compared; the field displacement rate was also varied. A rapid training procedure was used, and a novel one-trial test was employed that could measure the adaptation well enough to compare the effects of various training conditions. The one-trial test measured the magnitude of one of the manifestations of adaptation, the apparent displacement of a stationary target during head movements. This apparent horizontal target displacement was transformed into an oblique one by having the head movements that brought forth the apparent target displacement simultaneously cause an objective vertical target displacement. The slant of the resultant apparent motion path varied with the magnitude of the apparent horizontal target displacement. It was measured by having S reproduce its slant angle. It was found that adaptation to field displacement in the direction with the head rotation was consistently greater than adaptation to the opposite displacement conditions. An explanation for this result is offered.  相似文献

In the research area of multiple criteria decision making, very few publications exist that explicitly design the simulation of a decision maker (DM) in an interactive approach. For this reason, we outline some methods widely used in the literature to identify common assumptions of simulating the DM's responses and the required input preference information. Our paper aims at covering the identified gap by introducing experimental concepts. Such concepts are used for theoretical analyses of a combined search‐and‐decision‐making procedure. Simulating the DM is a fruitful idea because the algorithm can be tested without integrating a human decision maker. Finally, we conduct experiments based on the proposed settings for a multiobjective inventory routing problem, which is a relevant and challenging logistic problem.

In computer security parlance, a hacker is an individual who actively seeks and takes advantage of flaws and weaknesses of a computer network or system. In recent years, one has seen the rise of hacking, often as a form of protest and retaliation for reasons ranging from political to social, but the question remains as to what really motivates an individual to hack a computer network? Using the Q-method, the study aimed to develop a classification of the motivation of computer hackers. This was done with the use of 43 participants who were subjected to preliminary interviews and the sorting method. The statements from the interviews were categorized that resulted in seven conceptual themes, namely social-positive, social-negative, intellectual gain, self-satisfaction, economic rewards, technological-positive and technological-negative. From these themes, three distinct profiles emerged and were used to describe the motivation of hackers.  相似文献

At the end of the last decade severely violent and sexual crimes by previously convicted persistent offenders initiated a discussion about the necessity of quality control in the forensic psychiatric practice in Switzerland. Subsequently, measures similar to those in Germany were adopted, e.g. the implementation of a specialisation in forensic psychiatry. In addition, they included the creation of commissions with the duty of evaluating the dangerousness of serious offenders, the implementation of a standardized and certificated postgraduate training in forensic psychiatry and guidelines for the qualification of forensic assessment experts and the quality of reports. The following article presents the implemented measures and discusses their possible consequences for the quality of forensic psychiatric work.  相似文献

In a previous study (Unterrainer, Kaller, Halsband, & Rahm, 2006), chess players outperformed non-chess players in the Tower of London planning task but exhibited disproportionately longer processing times. This pattern of results raises the question of whether chess players' planning capabilities are superior or whether the results reflect differences in the speed-accuracy trade-off between the groups, possibly attributable to sports motivation. The present study was designed to disambiguate these alternative suggestions by implementing various constraints on planning time and by assessing self-reported motivation. In contrast to the previous study, chess players' performance was not superior, independently of whether problems had to be solved with (Experiment 1) or without (Experiment 2) time limits. As expected, chess players reported higher overall trait and state motivation scores across both experiments. These findings revise the notion of superior planning performance in chess players. In consequence, they do not conform with the assumption of a general transfer of chess-related planning expertise to other cognitive domains, instead suggesting that superior performance may be possible only under specific circumstances such as receiving competitive instructions.  相似文献

Public understanding of climate change in the United States   总被引:2,自引:0,他引:2  
This article considers scientific and public understandings of climate change and addresses the following question: Why is it that while scientific evidence has accumulated to document global climate change and scientific opinion has solidified about its existence and causes, U.S. public opinion has not and has instead become more polarized? Our review supports a constructivist account of human judgment. Public understanding is affected by the inherent difficulty of understanding climate change, the mismatch between people's usual modes of understanding and the task, and, particularly in the United States, a continuing societal struggle to shape the frames and mental models people use to understand the phenomena. We conclude by discussing ways in which psychology can help to improve public understanding of climate change and link a better understanding to action.
