Although the debate about whether an individual with a life-threatening illness should have the right to hasten his or her death continues, few researchers have examined why someone might consider such an option. This study examined factors that contribute to consideration of hastening death among people with life-threatening illnesses. A…

Extensive evidence indicates that the insular cortex (IC), also termed gustatory cortex, is critically involved in conditioned taste aversion and taste recognition memory. Although most studies of the involvement of the IC in memory have investigated taste, there is some evidence that the IC is involved in memory that is not based on taste. In…

This study investigated the role of Voice Onset Time (VOT) as perceptual cue to the aspiration contrast of Cantonese initial stops produced by adolescent profoundly hearing impaired speakers. Speakers with normal hearing signalled the aspiration contrast through VOT differences. Hearing impaired speakers produced initial stops with no significant…

Objective: Children and adolescents of the Gaza Strip have been subjected to continuous violence since the eruption of the second Intifada (Uprising). Little is known, however, about the psychological effects of this violence on children and adolescents of Gaza. Thus, the purpose of the present investigation was to evaluate and describe the…

This study evaluated the ability of the kindergarten and first grade Dynamic Indicators of Basic Early Literacy Skills (DIBELS), measures of early literacy development, to discriminate among low average, average, and above average students considered at risk emotional and behavioral disorders (EBD) on the Total Reading cluster of the Woodcock…

There is debate about whether the leadership style of the teacher or the learning style of the student affects academic achievement more. A large sample (n = 746) of eighth-grade students in Istanbul, Turkey, participated in a study where the leadership style of the teacher was assessed in terms of people orientation and task orientation. The…

This dissertation reports the results of an exploratory data analysis investigation of the relationship between the structures used for information organization and access and the associated storage structures within state government websites. Extending an earlier claim that hierarchical directory structures are both the preeminent information…

Accurate classification in discriminant analysis and the value of prediction are discussed, with emphasis on the uses and key aspects of prediction. A brief history of discriminant analysis is provided. C. J. Huberty's discussion of four aspects of discriminant analysis (separation, discrimination, estimation, and classification) is cited.…

To determine if coupon collecting has any influence on product information processing like brand awareness, and to understand better the coupon collecting process, an exploratory study examined the relationship between coupon-collecting behavior and brand awareness for the coupons collected. Subjects, 152 randomly chosen respondents from a Midwest…

THREE COLLEGES JOINED IN A STUDY OF STUDENT WITHDRAWAL. THE HYPOTHESIS OF THE STUDY PROPOSED THAT SIGNIFICANT DIFFERENCES EXIST AMONG STUDENTS IN THEIR LEVELS OF COMMITMENT TO HIGHER EDUCATION AS THE MAJOR OPPORTUNITY OF POST-HIGH-SCHOOL YEARS. STUDENTS WITH HIGH LEVELS OF COMMITMENT FACE PROBLEMS AND EITHER SOLVE OR TOLERATE THEM, WHILE THOSE…

The shape of the response surface associated with a discriminant analysis provides insight into the value of the derived optimal discriminant variates. A procedure for the determination of "indifference regions," presented in this article, allows the assessment of the degree of flatness of the response surface for any analysis.…

Assessed the personality differences between pregnant unwed young women who had a varying number of pregnancies and sexually active females. A discriminant function analysis was employed to predict group membership on the basis of the Minnesota Multiphasic Personality Inventory scales, which were used as predictor variables. (Author/BL)

A computer program for two-group nonparametric discriminant analysis is presented. Based on Bayes' Theorem for probability revision, the statistical rationale for this program uses the calculation of maximum likelihood estimates of group membership. The program compares the Bayesian procedure to the standard Linear Discriminant Function.…

We consider the problem of classifying an unknown observation into one of several populations using tree-structured allocation rules. Although many parametric classification procedures are robust to certain assumption violations, there is need for discriminant procedures that can be utilized regardless of the group-conditional distributions that…

Scores on different items of a test are often combined linearly (sometimes with equal weights) to form the test score, mainly for the sake of computational convenience. In this paper, the author studies the consequences of doing this, and also studies the problems involved in finding a suitable linear combination. (Author/RK)
