Objective: Interorganizational relationships (IORs) between child welfare agencies and mental health service providers may facilitate mental health treatment access for vulnerable children. This study investigates whether IORs are associated with greater use of mental health services and improvement in mental health status for children served by…

School, parental and peer group effects have been identified as being influential in shaping the decision of students to participate in post-compulsory education, but the analysis of each effect separately is rare. Using a random effects logistic regression approach, estimates of the importance of school, parental and peer group effects on student…

We evaluate the impact of Florida's test-based promotion policy on the probability that low-performing students are retained using data on the universe of third-grade students in the state of Florida from 2001 to 2004. We also examine the effect of formal exemptions to the policy on student proficiency in reading two years later. In an evaluation…

Harsanyi's utilitarianism is extended here to Savage's framework. We formulate a Pareto condition that implies that both society's utility function and its probability measure are linear combinations of those of the individuals. An indiscriminate Pareto condition has been shown to contradict linear aggregation of beliefs and tastes. We argue that…

This article describes a simple classroom activity that helps students immediately visualize and understand the meaning and mathematical properties of the Poisson distribution.

In this article, we study the Monty Hall three doors problem. A fully general solution and several new approaches are presented, including a Bayesian analysis.

This article shows how the use of factorial moments provides a simple, consistent yet elegant approach to finding the mean and variance of standard discrete probability distributions.

This paper examines a real life question of gamble facing lottery players. Combinatorial dependence plays a central role in shaping the game probabilistic structure, but might not carry the merited weight in punters' considerations.

Several probabilistic models for subset choice have been proposed in the literature, for example, to explain approval voting data. We show that Marley et al.'s latent scale model is subsumed by Falmagne and Regenwetter's size-independent model, in the sense that every choice probability distribution generated by the former can also be explained by…

Just as organizations use strategic planning to prepare for the future, individuals and the organization can benefit from personal strategic plans that consider future pathways within the organization as part of those plans. This research proposes a three-step approach to creating personal strategic plans that incorporates personal research,…

Two experiments with pigeons investigated the effects of contingencies between interresponse times (IRTs) and the transitions between the components of 2- and 4-component chained schedules (Experiments 1 and 2, respectively). The probability of component transitions varied directly with the most recent (Lag 0) IRT in some experimental conditions…

As women have entered the work force and occupational sex segregation has declined, workers experience increased contact with the opposite sex on the job. The sex mix a worker encounters on the job should affect the cost of search for alternative mates and therefore the probability of divorce. This paper uses 1990 Census data to calculate the sex…

The cerebral hemispheres have been shown to be differentially sensitive to sentence-level information; in particular, it has been suggested that only the left hemisphere (LH) makes predictions about upcoming items, whereas the right (RH) processes words in a more integrative fashion. The current study used event-related potentials to jointly…

A connectionist model of causal attribution is presented, emphasizing the use of domain-general principles of processing and learning previously employed in models of semantic cognition. The model categorizes objects dependent upon their observed 'causal properties' and is capable of making several types of inferences that 4-year-old children have…
