Promoting principals' managerial involvement in instructional improvement

Studies of school leadership suggest that visiting classrooms, emphasizing achievement and training, and supporting teachers are important indicators of the effectiveness of school principals. The utility of a behavior-analytic program to support the enhancement of these behaviors in 2 school principals and the impact of their involvement upon teachers' and students' performances in three classes were examined in two experiments, one at an elementary school and another at a secondary school. Treatment conditions consisted of helping the principal or teacher to schedule his or her time and to use goal setting, feedback, and praise. A withdrawal design (Experiment 1) and a multiple baseline across classrooms (Experiment 2) showed that the principal's and teacher's rates of praise, feedback, and goal setting increased during the intervention, and were associated with improvements in the academic performance of the students. In the future, school psychologists might analyze the impact of involving themselves in supporting the principal's involvement in improving students' and teachers' performances or in playing a similar leadership role themselves.     

风险决策中的参照点效应研究

本研究以展望理论和社会决策范式模型为基础,着重探讨三种参照点对个体和群体风险决策产生的影响。３００名被试经实验者设置参照点后分别在个体和群体条件下对不同风险度的博弈方案进行选择。结果表明：（１）个体决策中,损失参照点的被试和无得失经验者比得益者更冒险;（２）得益被试的决策受到社会比较的影响;（３）损失参照点的被试并未对群体决策有更大影响,决定群体决策结果的主要是多数原则。     

Complexities in Cancer Risk Counseling: Presentation of Three Cases

Complexities abound in the identification and management of families at increased risk for inherited forms of cancer. One of the ways to learn as a profession how best to provide cancer risk counseling (CRC) is to share counseling experiences. Such cases can provide insight into the issues raised by families and ways in which genetic counselors have handled complex situations. Here we describe three CRC cases initially presented at the 1995 American College of Medical Genetics meeting. The first case involves balancing the importance of informing a family of the presence of an inherited cancer syndrome with the family's right not to know. The second case illustrates the difficulties in assisting an individual to make medical management decisions in the face of uncertain risk information. The third case describes the complex interactions with a woman before and after her decision to have prophylactic surgery.

Cancer Risk Counseling: How Is It Different?

Fifty-six of 80 (70%) full members of the National Society of Genetic Counselors with interest in cancer genetics responded to a 1994 survey regarding their cancer risk counseling practices. This study was undertaken to describe cancer risk counselors and the services they provide and to identify possible differences from general genetic counseling that warrant further study. Of 56 respondents, 41 (75%) were providing CRC. The components of CRC programs are described. Our results found significant differences between CRC and general genetic counseling in terms of training and experience of genetic counselors providing CRC and length and number of counseling sessions per consultand. 51% of respondents had 1–2 years of working in CRC, compared to 17% with 1–2 years experience in genetic counseling (p<0.05). Over one-third had 10 or more years genetic counseling experience. Counselors were more likely to see individuals at risk for cancer for longer counseling sessions (p<0.05) and for additional sessions (p<0.05).     

The Familial Cancer Program of the Vermont Cancer Center: Development of a Cancer Genetics Program in a Rural Area

In response to many scientific discoveries linking cancer in certain families to inherited factors, the Vermont Cancer Center established the Familial Cancer Program (FCP) in December 1993. This multifaceted program combines the expertise of clinicians and researchers in many disciplines, including genetics, oncology, psychology, and molecular biology. The program's goals are identification of families in its region with excess cancer, provision of clinical services to such families, and use of research protocols when available and appropriate. This article describes the experience of setting up a familial cancer program in a rural area and discusses both successes and challenges in such an endeavor.     

Effects of Performance-Based Pay Systems on Quantity and Quality in Computer Programming

This experiment was conducted to investigate the effects of quality-contingent pay systems on quantity and quality. Three computer science students were paid to create simple computer programs across 25 sessions. A multiple-baseline across subjects design was used to compare the effects of three kinds of pay systems; pay-for-hour, pay-for-quantity, and pay-for-quality systems. The quantity was higher when pay was based on the quantity of the programs produced, and the quality was highest when pay was based on the quality of the programs. The production cost including quality inspection costs was highest when pay was based on the time worked.     

EFFECTS OF CHOOSING ACADEMIC ASSIGNMENTS ON A STUDENT WITH ATTENTION DEFICIT HYPERACTIVITY DISORDER

The effects of choosing academic assignments on the undesirable behaviors manifested by a second-grade student with attention deficit hyperactivity disorder were analyzed. This study extended Dunlap et al.'s (1994) research on choice making as a form of antecedent control. A reversal design showed that undesirable behaviors decreased when the student was given a choice of academic assignments.     

A SUPERVISION PROGRAM FOR INCREASING FUNCTIONAL ACTIVITIES FOR SEVERELY HANDICAPPED STUDENTS IN A RESIDENTIAL SETTING

This study was designed to increase the amount of time severely handicapped students living in a residential facility engaged in age-appropriate and functional activities. After a brief in-service training, a program involving instructions to supervisors and staff feedback was implemented in a multiple-baseline design across settings. Results showed that after the supervision program was implemented, the students' participation in activities increased. Further, these increases maintained when feedback was reduced from an average of 3 days a week during treatment, to once a month for a 5-month period.     

Hypothetical and real consequences in experimental auctions for insurance against low-probability risks

Laboratory experiments have provided useful information about how people behave in risky situations. In particular, such experiments have allowed for the observation of many deviations from the predictions of expected utility theory. There is some dispute, however, over the effect of the use of real versus hypothetical money in these experiments and over the impact of experience. In this paper we describe auction experiments in which subjects faced a low-probability risk with either hypothetical or real-money consequences and varying amounts of experience. Using hypothetical payoffs resulted in behavior that provides a reasonable qualitative prediction of behavior with real consequences, but that seems to indicate a less diligent altitude toward spending the money as well as less concern about the risk.
