Although cases of anorexia nervosa and bulimia are being seen increasingly by health care professionals, little data is available on the prevalence of these disorders in the general population of school age children. Using a validated eating attitude test (EAT), a total of 5150 students, aged 12–20, from public schools and one university in the Province of Manitoba were surveyed. Overall, 5% of males and 22% of females scored 30 or above on the scale, suggesting significant concerns and attitudes regarding eating. These concerns were somewhat higher in urban versus rural settings and seemed to increase between the ages of 12 and 13 and remain high thereafter. Many of the students who scored high on the EAT were overweight, suggesting that these attitudes or concerns are not specific to anorexia nervosa and/or bulimia.

One hundred alcoholics treated for ethanol withdrawal were assigned randomly according to a double-blind protocol to receive four intramuscular injections of 2 g of magnesium sulfate at 6-hr intervals or an equivalent amount of normal saline. All patients were treated for signs of withdrawal according to a standardized protocol using orally-administered chlordiazepoxide for sedation. Three observers rated each patient for signs of withdrawal. There was no statistically significant difference between magnesium sulfate and placebo groups on any of the variables measured. The groups required equivalent amounts of chlordiazepoxide for control of withdrawal. The authors concluded that the routine administration of magnesium sulfate is not indicated for the management of alcohol withdrawal unless accompanied by cardiac arrhythmias.

I surveyed 2 samples of Canadian undergraduates (N = 629) concerning their views of a "perfect instructor." Students identified as many descriptors as they wished; I categorized them into 26 sets of qualities and behaviors. The top 10 categories included: (a) knowledgeable; (b) interesting and creative lectures; (c) approachable; (d) enthusiastic about teaching; (e) fair and realistic expectations; (f) humorous, happy, and positive; (g) effective communicator; (h) flexible and open-minded; (i) encourages student participation; and (j) encourages and cares for students. Of the 26 categories, 24 are akin to those found by Buskist, Sikorski, Buckley, and Saville (2002), reflecting an almost equal emphasis on teaching technique and the student-teacher relationship. These findings offer international support for their categories of effective teaching.Research examining student-centered views of effective teaching has sought to identify both negative and positive attributes of teachers in an attempt to enhance teaching effectiveness. For example, Perlman and McCann (1998) identified students' "pet peeves" about teacher behavior. More recently, Miley and Gonsalves (2003) measured students' perceptions of "annoying teaching habits." * p < .025. * * p < .01. * * * p < .001.

The present paper (1) contrasts the prevalence of marijuana use and involvement with marijuana among 194 delinquent and 405 nondelinquent adolescents, (2) examines the utility of an expanded version of Jessor and Jessor's (1977) problem behavior model in predicting adolescent marijuana use, and (3) tests the relative importance of the predictors of marijuana use. Personality variables that were added to the Jessor problem behavior model included: (1) stimulus reducing - augmenting, (2) ego strength, (3) anxiety, and (4) field dependence. Results showed that delinquents reported using marijuana more often than nondelinquents. In the multiple regression analyses the expanded model explained a slightly greater percentage of the variance in adolescent marijuana use than the Jessor and Jessor model. Of the added personality variables, the Vando (1969) Reducer--Augmenter dimension seemed to be a particularly significant predictor. In addition, reducing--augmenting seemed to be a better predictor of involvement with marijuana than several previously used personality and demographic variables since it replaced these in the final regression equation. Perceived environment variables measuring pressure from friends to use marijuana and friends as models for marijuana use were the best predictors of marijuana use.

In this study predictors of successful smoking cessation among 166 clients of a smoking cessation program were examined via multiple regression analyses. Results showed that seven significant predictors accounted for 25% of the variance in successful smoking cessation. Abstainers tended to have higher incomes, to rate pregnancy as a motivation more highly, to have made fewer previous attempts to quit, to be low on habit smoking, to crave cigarettes more in low-arousal situations, to be stimulus reducers, and to be older.
