Argues that Gottlieb rejects population sampling and statistical analyses of distributions as he proposes that his experimental brand of mechanistic science is the only legitimate approach to developmental research. Maintains that Gottlieb exaggerates developmental uncertainty, based on his own research with extreme environmental manipulations.…

Purpose: In an attempt to more thoroughly describe aggressive behavior in nursing home residents with dementia, we examined background and proximal factors as guided by the Need-Driven Dementia-Compromised Behavior model. Design and Methods: We used a multivariate cross-sectional survey with repeated measures; participants resided in nine randomly…

This study involved two phases: first when classification was based on the calibration sample, and second in a cross-validation setting. Computer-generated data were used. Results obtained from rules based on probabilities of group membership were compared for accuracy when classifying in the discriminant space and in the predictor variable…

Expressions for the expected value, density, and distribution function (DF) of GS (gain from selection) are derived and studied in terms of sample size, number of predictors, and the prior distribution assigned to the population multiple correlation. (Author/RK)

Discusses the interdependencies between parameter estimation and properties of probabilistic models, such as dependency assumptions, binary vs. nonbinary features, and estimation sample selection. An optimum estimation for binary features applicable to information retrieval is defined, a method for computing this estimation using empirical data is…

Using American Citizen Participation Survey data (Verba et al. 1995a), we perform logistic regression analyses to adjudicate between three core explanations for individual protest: biographical availability, political engagement and structural availability. We calculate estimated probabilities to weigh the relative effects of these factors on the…

Objectives: Characteristics of the child victim, perpetrator, and maltreatment incident were used to examine predictors of court involvement in cases of serious child maltreatment. Method: Cases were drawn from those reported to: child protective services (n = 225), "sheriff's office" ( n = 225), "prosecutor's office" ( n = 60), "and dependency…

When a simple random sample of size n is employed to establish a classification rule for prediction of a polytomous variable by an independent variable, the best achievable rate of misclassification is higher than the corresponding best achievable rate if the conditional probability distribution is known for the predicted variable given the…

The Peer-Assisted Learning (PAL) program at the University of Minnesota has drawn from the best practices of Supplemental Instruction, Peer-Led Team Learning, Structured Learning Assistance, the Emerging Scholars Program, and other successful postsecondary peer cooperative learning models to establish guiding principles for structuring learning…

In this paper, we explore the rules that determine intuitive predictions and judgments of confidence and contrast these rules to the normative principles of statistical prediction. (Author)

Prior research into factors predicting arrest in domestic violence cases is limited in three regards: (a) no examination of whether mandatory arrest policies are associated with increased risk of arrest across multiple jurisdictions; (b) little consideration of whether police organizational characteristics influence arrest in such cases; and (c)…

Objective: The validity and clinical utility of the Reynolds Adolescent Depression Scale, Beck Hopelessness Scale, Suicidal Ideation Questionnaire-Junior, and Suicide Probability Scale (SPS) were examined longitudinally among suicidal adolescents. Method: Between 1998 and 2000, 289 psychiatrically hospitalized, suicidal youth, ages 12 to 17 years,…

Examines the propensity of teachers to strike and, using a logit model, how this propensity can be affected by certain decision variables, notably a teacher's political leaning, sex, cynicism, moonlighting, colleague orientation, orientation to the public, age, teaching load, total family income, morale, and attitude toward peer evaluation.…

The effect of certain methodological changes on the fit of the Wyer subjective probability model and the effect of belief change on cognitive structure were investigated. Using syllogistically-related proposition sets of the form "A,""If A then B,""If not A then B,""B," it was found that certain…

Description of the characteristics and mechanics of the Delphi technique of identifying the likelihood of occurrence of specified future events precedes suggested uses for the technique in research, planning, and teaching. The procedure involves obtaining individual predictions, aggregating results, presenting results to the individuals, and…
