The Value of Instructional Communication in Crisis Situations: Restoring Order to Chaos

This article explores the nature of instructional communication in responding to crisis situations. Through the lens of chaos theory, the relevance of instructional messages in restoring order is established. This perspective is further advanced through an explanation of how various learning styles impact the receptivity of various instructional messages during the acute phase of crises. We then summarize an exploratory study focusing on the relationship between learning styles and the demands of instructional messages in crisis situations. We conclude the article with a series of conclusions and implications.     

Connotative Meanings Assigned to Contraceptive Options

Abstract

The authors surveyed a stratified sample of 880 colleges and universities in the United States to assess the status and characteristics of their prematriculation immunization requirements (PIRs). On the basis of a 90% return (796 responses), they estimated that 55% of US colleges and universities had implemented a PIR at the time of the survey. Among schools with PIRs, measles vaccine was almost universally required, with 74% requiring two doses, mumps vaccine was required by 70%, and rubella vaccine by 92%. Hepatitis B vaccine was rarely required and was usually recommended only for students in health-profession programs. The strongest determinant of having a PIR was the presence of a state law or regents' policy. PIRs implemented under the aegis of a state law were, on average, less comprehensive but better enforced. Other factors associated with the implementation of a PIR included membership in the American College Health Association (ACHA), the presence of a student health clinic, and availability of record-keeping personnel.     

Missing data estimators in the general linear model: an evaluation of simulated data as an experimental design

Previous simulations have reported second order missing data estimators to be superior to the more straightforward first order procedures such as mean value replacement. These simulations however were based on deterministic comparisonsbetween regression criteria even though simulated sampling is a random procedure. In this paper a simulation structured asan experimental design allows statistical testing of the various missing data estimators for the various regression criteria as well as different regression specifications. Our results indicate that although no missing data estimator is globally best many of the computationally simpler first order methods perform as well as the more expensive higher order estimators, contrary to some previous findings.     

The influence of nonverbal cues associated with looking behavior on young children's mentalistic attributions

The ability of children to use looking behavior as a cue to guide their mentalistic attributions was assessed. In Experiment 1 video displays were presented in which a protagonist faced one of two potential goals, half of the time standing equidistant from both targets and in the remaining trials standing closer to the target not being faced. Preschoolers consistently based their inferences of another's attention and goal on the direction in which the protagonist was facing. However, in Experiments 2 and 3 preschoolers experienced difficulty in correctly inferring an actor's desired goal when the protagonist's body was oriented in a direction opposite of where she was looking. Under these conditions, only young elementary school children consistently inferred that the protagonist's goal was the target being looked at (Experiment 2). The results from these three studies suggest that an important development occurring in childhood is the ability to consistently distinguish gaze from body orientation when inferring the goals of another. The implications of this development for children's understanding of the mind are discussed.     

Change from within: The ABC‐AME church

This article describes the dilemma of a senior pastor whose urban church lost its community focus as the congregation became more affluent. His task was to determine what role the church should play in helping its less fortunate neighbors and how to get the members to support this new vision. Where there is no vision the people perish. —Proverbs 29:18     

Using success to measure quality in British higher education: which subjects attract the best-qualified students?

Summary. A theory is developed to measure the quality of applicants into UK higher education. It is based on the principle that more able applicants will self-select into more difficult subject choices. The advantage is that it gives a unidimensional measure whereby different groups can easily be compared across any dimension of interest, e.g. men, women and the various ethnic groups. Here the relative quality of applicants and acceptances across 170 separate subject groups is calculated and discussed by using a data set with over 2 million observations. It, therefore, offers a way of achieving a more refined measure of the quality of human capital.
