In this paper we propose an approach which makes it possible to search non-dominated and only non-dominated solutions in multiple-objective linear programming. The approach is based on the use of a reference direction and lexicographic parametric programming. The requisite theory is developed in the paper. The use of the approach is illustrated with a numerical example. 相似文献

We report two studies on rapid serial naming (RSN). Study 1 addressed the relations among RSN tasks comprising different stimuli. Separate components for RSN of alphanumeric and non-alphanumeric stimuli, as well as for tasks in which the stimuli alternated between categories were identified. In Study 2, phonological skills, processing speed, motor dexterity, and verbal fluency were found to explain RSN performance. The studies indicate: (1) that RSN tasks vary in their properties according to the stimuli used and according to the way the tasks are arranged, and (2) that RSN tasks are multi-componented. 相似文献

Neuroticism is a predictor of many health problems. To study the determinants of within‐subject change in neuroticism, three hypotheses were tested: (i) subjects who experienced stressful life events (SLEs) show an increase in neuroticism; (ii) high baseline neuroticism moderated this effect; and (iii) recent SLEs had a greater impact on neuroticism than distant SLEs. Data came from the Finnish Twin Cohort. Neuroticism data were collected in 1975 and 1981 and SLEs data in 1981 (n = 21 085). By entering baseline neuroticism as a predictor for neuroticism at follow‐up, the outcome measure was change in neuroticism. Changes in neuroticism were predicted from SLE indices or their interaction with baseline neuroticism. Timing of SLEs was taken into account by distinguishing recent from distant SLEs. To control for confounding by shared genes and environments, both within‐twin pair and between‐twin pair effects were tested for monozygotic and dizygotic twin pairs separately. Neuroticism's six‐year stability was high (r = .58, p < .001). Exposure to SLEs modestly increased neuroticism (βs > .55, ps < .001), unconfounded by shared genes. This effect was not moderated by high baseline neuroticism. Recent SLEs (.09 < βs < .15) had more impact than distant SLEs (.03 < βs < .11; ps < .01). In conclusion, the findings strongly supported a model of environmentally driven SLEs causing dynamic fluctuations around a person's set point of neuroticism.

Illusory face perception, a tendency to find human‐like faces where none are actually present in, for example, artifacts or scenery, is a common phenomenon that occasionally enters the public eye. We used two tests (N = 47) to analyze the relationship between paranormal and religious beliefs and illusory face perception. In a detection task, the participants detected face‐like features from pictures of scenery and landscapes with and without face‐like areas and, in a rating task, evaluated the face‐likeness and emotionality of these areas. Believer groups were better at identifying the previously defined face‐like regions in the images but were also prone to false alarms. Signal detection analysis revealed that believers had more liberal answering criteria than skeptics, but the actual detection sensitivity did not differ. The paranormal believers also evaluated the artifact faces as more face‐like and emotional than the skeptics, and a similar trend was found between religious and non‐religious people.

This study set out to investigate parental attitudes toward entrepreneurship education as evaluative directing components of social representations. A nationwide sample of parents (N = 625) was asked to indicate their opinions on a set of statements about entrepreneurship education. The parents’ attitudinal orientation suggested that they would rather avoid entrepreneurship education than approach it. Additionally, parental evaluations contained indecision and polarised opinions, and most parents saw it as unlikely or were unsure whether their children would become entrepreneurs. Parental attitudes correlated with the established representations of education and subsequent policy stands, suggesting that entrepreneurship education has been made familiar by anchoring attitudes in the field of educational debates. It was suggested that current trends in educational policy and work life may stimulate the formation of polemical social representations pertaining to entrepreneurship education. 相似文献

This study investigates the influence of a decision aid on decision makers' model‐based choices, emotions during the use of the model, and attitudes towards the model. A time allocation decision model was biased to purposefully provide optimistic or pessimistic criterion levels, on which subjects based their allocations. The results of our experiment indicate that the degree of “optimism” and “pessimism” inherent in the decision model had a significant impact on the decision maker's choices of criterion values, with optimism leading to higher criterion level choices and pessimism to lower levels. Furthermore, compared to pessimistic models, optimistic models significantly improved the decision makers' emotional states and, to some degree, their attitudes towards the decision aid. The implications of these conscious and sub‐conscious influences on decision makers' choices, emotions, and attitudes are discussed and the need for model‐builders and users to be aware of them is highlighted.

Direction and the frequency of spontaneous head movements during the ITIs following forward and backward paired trials were
compared to an acquisition of a conditioned orienting (alpha) response directed to the side of the tone source. The head movements
were analyzed from video recordings using classification of head turns to preferred and to nonpreferred directions. The results
showed a significant increase in the alpha responses during the forward paired conditioning to the preferred direction and
rapid extinction during the subsequent backward conditioning sessions. Spontaneous head movements during the ITIs increased
to the same preferred direction as the conditioned alpha responses. The results of this experiment suggest that the response
initially elicited by the CS can later appear as “spontaneous,” instrumental behavior, the form and the nature of which is
determined by the characteristics of the conditioned alpha response developing as a result of classical conditioning. 相似文献

In this paper the authors suggest that instead of holding the view that the sequence of therapy follows the path of first interviewing and gathering data, then understanding and finally intervening on the basis of what is thought to be the cause of the problem, we could benefit from recognizing that the reverse view is equally plausible. According to this reverse view, which the authors call hindsight, therapists, unaware of it themselves, first come up with interventions and then, in hindsight, create explanations or particular ways of understanding problems in order to make their interventions seem rational and justifiable. A number of factors influencing therapists' choice of interventions are explored. Finally some potential advantages of the hindsight view are examined. 相似文献
