The Regrettable Necessity of Contingent Valuation

Ordinary markets allow parties, not the state, to value property and projects. But they do not account for subjective value in such traditional contexts as condemnation. An awareness of these nonmarket values helps overcome any categorical opposition to the use of the contingent valuation method (CVM) to value cultural and environmental resources. But accurate CVM should measure all values, positive or negative, tononowners; it should apply generally to any substitute projects; and it should seek to account for diminishing marginal value of additional resource units. CVM should be used only to aggregate nonmarket preferences, not to skew the political debate to cultural or environmental objectives.     

Staff development planning in an academic health sciences library.

OBJECTIVE: A staff development committee (SDC) was convened to implement staff development opportunities for an academic health sciences library system comprised of three separate facilities. The charge for the SDC was to: (1) develop programs to enhance workplace skills and personal growth, (2) communicate the availability of existing programs at the university and medical center, and (3) encourage the staff to participate in these opportunities. PROGRAM: The committee created goals and objectives and developed a survey designed to give staff the opportunity to provide input for this initiative. With an 80% response rate, the survey results were used to plan 15 events based on staff needs and preferences. First-year attendance for SDC-sponsored events was 459. Committee members served as liaisons for each event. Two forms were developed to facilitate event planning. A monthly announcement sheet, email reminders, and the library's local area network are used to communicate upcoming SDC events and encourage attendance. CONCLUSION: This approach can serve as a useful model for similar program planning in any organization.     

Decreasing “obscene” language of behaviorally disordered children through the use of a DRL schedule

The purpose of the present study was to determine the value of DRL schedules in reducing the behavior of a group of behaviorally disordered children. During the DRL procedure, reinforcement was made available for inappropriate language that was less than a prescribed limit for each day. When the DRL limit was successively decreased across weeks, the behavior of the students systematically decreased. Data indicated that reinforcing low rates of behavior may be an effective alternative to the use of aversive contingencies to reduce the misbehavior of such children.     

Effects of Proximity on the Choice to Be Physically Active or Sedentary

The link between physical activity and weight loss has precipitated interest in interventions to foster adherence to exercise. It has been suggested that treatment effects, when significant, should be analyzed to determine theory-based mediators. This research assessed possible mediation of changes in Physical Self-Concept, Exercise Self-Efficacy, Total Mood Disturbance, and Body Areas Satisfaction scores on the relationship between exercise session attendance and participation by obese women in a 6-month treatment based on tenets of social cognitive theory (n = 73) or a control condition (n = 64). Participation in the treatment was associated with significantly greater exercise session attendance and significantly greater improvements in Physical Self-Concept, Exercise Barriers Self-Efficacy, and Body Areas Satisfaction. Overall, changes in the assessed psychological factors demonstrated significant mediation of the association between group membership and exercise session attendance, R² = .23, with only change in Physical Self-Concept scores providing a significant unique contribution. Extensions of this research across different sample types, and with longer durations, were suggested to refine theory and, ultimately, improve exercise adherence treatments.
