Our objective in this paper is to propose a procedure for solving a multicriteria assignment problem. Given qualitative and quantitative data, the proposed procedure makes assignments taking into consideration the multicriteria aspect of the problem. As an illustrative example, we consider the assignment of referees to the football matches in an Italian championship. Copyright © 2003 John Wiley & Sons, Ltd. 相似文献

Four studies are reported which link developmental increases in memory span with developmental increases in operational speed or efficiency. In the first, a linear relationship is demonstrated between increases in word span and increases in speed of word repetition. In the second, adults and 6-year-olds are equated on speed of word repetition, by manipulating word familiarity. It is shown that their word spans are no longer different under these conditions. Similar findings are then reported for a test of M space called “Counting Span.” First, a linear relationship is demonstrated between increases in Counting Span and increases in speed of counting. Next, adults and 6-year-olds are equated on speed of counting, by forcing adults to count in an unfamiliar language. It is shown that their counting spans are no longer different under these conditions. The conclusion is that developmental increases in memory span do not result from increases in total processing space. Rather, with development, basic operations become faster and more efficient. This means that they require less processing space, and that more space becomes available for storage as a result. 相似文献

An experiment demonstrated a complete hemispheric processing reversal in 10 male, dysphonetic dyslexic children that occurred during a dichotic listening test of their verbal working memory. Requiring a written response to dichotic digits produced a right hemisphere/left ear superiority in the dysphonetic dyslexics whereas normal subjects and other dyslexics maintained a left hemisphere/right ear advantage. This reversal was unaffected by changes in task difficulty. A second experiment assessed the influence on producing the reversal of concurrent manual interference with left hemisphere verbal processing (responding orally vs. manually) and selective right hemisphere priming (Forward Writing vs. Backward Writing). The dysphonetic children reverted to a strong left hemisphere superiority when recalling the dichotic digits orally. Backward writing produced no ear advantage in either direction. The findings suggest that dysphonetic dyslexia may be related to (1) left hemisphere processing demands that exceed capacity, (2) easily activated right hemisphere processing strategies and (3) failure to coordinate linguistic processing interhemispherically. The results supported a novel hybrid conceptualization of dyslexia consisting of a synthesis of selective activation, and dual processor-limited capacity, theories. 相似文献

The ELECTRE family of decision aid methods is a well‐known approach to help decision makers (DMs) advance in a decision process. Among the most recent methods in the family, ELECTRE IS, III, and TRI compute fuzzy indices for the credibility of a given action outranking some other. We consider the case when the DMs are unsure which values each parameter should take, which may result from insufficient, imprecise or contradictory information, as well as from different preferences among a group of DMs. In the framework of a robustness analysis approach, where DMs provide only partial information on the parameter values (through constraints on acceptable combinations), we study how to find whether an outranking among two actions in an ELECTRE method is robust. In this context, we study the resulting nonlinear problems of optimizing a credibility index (under the type of constraints that we consider to appear in practice) and present some examples.

International comparisons of IQ test norms show differences between nations. In the present study, nonverbal reasoning, processing speed and working memory subtest scores of the US, German, French, Finnish, and Scandinavian (combined Swedish‐Norwegian‐Danish sample) WAIS IV standardization samples were compared. The European samples had higher scores on the reasoning subtests compared to the American sample, corroborating earlier studies. The Finnish and Scandinavian samples had lower processing speed and working memory scores than the American, German, and French samples. Mechanisms that may underlie the observed national IQ profiles include: (1) test‐taking attitudes—in tests that require balancing speed and accuracy of performance Americans may prioritize fast performance while Europeans avoid mistakes; (2) differences between languages in digit articulation times; and (3) educational factors—the European advantage on reasoning subtests may be based on there being better educational systems in Europe as compared to the US. 相似文献
