A new multiobjective linear programming (MOLP) algorithm is presented. The algorithm uses a variant of Karmarkar's interior-point algorithm known as the affine-scaling primal algorithm. Using this single-objective algorithm, interior search directions are generated and used to provide an approximation to the gradient of the (implicitly known) utility function. The approximation is guided by assessing locally relevant preference information for the various interior directions through interaction with a decision maker (DM). The resulting algorithm is an interactive approach that makes its progress towards the solution through the interior of the constraints polytope. 相似文献

The present study examined the influence of cultural background on the experience of loneliness. One hundred and ninety-four
Canadians and 209 participants from the Czech Republic formed the subject pool. Rather than compare the two populations and
disregard the within and between age differences, the cultural groups were divided into age subgroups. These were young adults
(18–30 years old), adults (31–59) and seniors (60–89). They answered a 30-item yes/no questionnaire. The questionnaire is
composed of five subscales, namely. Emotional Distress, Social Inadequacy and Alienation, Growth and Discovery, Interpersonal
Isolation, and Self-Alienation. Results indicated that overall, the cultural groups differed in their experiences of loneliness.
Further, when each age group was compared across the two cultures, it was evident that the age groups scored significantly
differently from its counterparts in the other culture. Scores of different age groups within cultures were also examined.

Anxiety is a common co-occurring problem among young people with autism spectrum disorders (ASD). Characterized by deficits
in social interaction, communication problems, and stereotyped behavior and restricted interests, this group of disorders
is more prevalent than previously realized. When present, anxiety may compound the social deficits of young people with ASD.
Given the additional disability and common co-occurrence of anxiety in ASD, we developed a manual-based cognitive-behavioral
treatment program to target anxiety symptoms as well as social skill deficits in adolescents with ASD [Multimodal Anxiety
and Social Skills Intervention: MASSI]. In this paper, we describe the foundation, content, and development of MASSI. We also
summarize data on treatment feasibility based on a pilot study that implemented the intervention. 相似文献

Mainstream theories of the Stroop effect suggest that faster colour classification on congruent trials (say, the word RED printed in red colour) relative to incongruent trials (GREEN in red) is due to channel interaction. Namely, information from the irrelevant word channel perturbs processing of the print colour, causing in turn slower processing of incongruent displays. In this note, I advance a new model in which colour and word are processed in parallel and completely independent channels. The Stroop effect is then the outcome of signal redundancy in congruent displays, where both colour and word contribute to the same response. Numerical computations show that the model can produce the Stroop effect (along with high accuracy rates) for a subset of parameter values. Thus, it provides a proof of existence for a separate channel theory, and a challenge to many existing theories. 相似文献

Against the background of the exclusion of many feminist methodologies from mainstream philosophy, and in light of the methodological challenges of providing accounts of experience responsive to the lives of agents, in this paper I return to early feminist philosophers of emotion to highlight how they anticipate and respond to methodological criticisms. Sue Campbell (1956–2011) was one philosopher who used methodological quandaries to strengthen her account of the formation and expression of feelings (Campbell 1997 ). By rereading selected texts together intentionally for their structural and methodological strategies, I emphasize the power of formal characteristics to make insightful claims about experience possible. I consider how feminist philosophers of “experienced agency” can put these strategies to use in facing ongoing methodological criticisms, taking as a case study an account of how it can feel to act responsibly against injustice. 相似文献

One variable is said to “stochastically dominate” another if the probability of observations smaller than x is greater for one variable than the other, for all x. Inferring stochastic dominance from data samples is important for many applications of econometrics and experimental psychology, but little is known about the performance of existing inferential methods. Through simulation, we show that three of the most widely used inferential methods are inadequate for use in small samples of the size commonly encountered in many applications (up to 400 observations from each distribution). We develop two new inferential methods that perform very well in a limited, but practically important, case where the two variables are guaranteed not to be equal in distribution. We also show that extensions of these new methods, and an improved version of an existing method, perform quite well in the original, unlimited case. 相似文献

Based on the content analysis of verbatim reports of loneliness accounts provided by 526 subjects, I developed a three-level model of the experience of loneliness. Ten factors are subsumed under four major elements and are differentiated into 23 components. In addition to demonstrating the complexity of loneliness, the present study also highlights the sources of the subjective experience and the varied accounts reported by so many writers. This model may be useful in designing therapeutic intervention procedures according to individual needs of the lonely and in examining the various conditions that give rise to the different experiences of loneliness that people report. 相似文献

Content analysis of the sexual fantasies of 87 community college and university students revealed no significant sex differences in the content of sexual fantasies. Both men and women preferred traditional and facilitative fantasies. Because this study was explorative, however, further research is required to validate the suggested scale and replicate these results. 相似文献
