Family history in ovarian cancer referral population

In order to determine the incidence of familial and hereditary ovarian cancer in a referral patient population, we conducted a retrospective study of 44 patients from a consecutive set of 62 patients treated for ovarian carcinoma at the Gynecologic Oncology Clinic at the Richland Memorial Hospital Center for Cancer Treatment and Research between January 1, 1993 and December 31, 1993. In our study of the referred patients, only two (4.55%) reported a history of at least one first-degree relative also being affected with ovarian cancer. However, 13 patients (29.55%) reported a family history consistent with one of the hereditary ovarian cancer syndromes. In addition to having a suggestive family history, these 13 families demonstrated several cardinal features of hereditary cancer syndromes including early onset, bilaterality, multiple primary tumors, and transmission. Race was the only significantly different demographic factor between the hereditary and sporadic ovarian cancer groups. All 13 patients who appeared to have a hereditary form of cancer were Caucasian.     

Assessment of mood states: Biases in single-administration assessments

Rasmussen, Jeffrey, Willingham, and Glover (1994) demonstrated that single-administration values derived from the Profile of Mood States (POMS) were biased estimates oftypical mood state. Like the previous study, the present study investigated whether single-administration POMS scores would be similar to average POMS scores derived from multiple administrations. In addition, in this investigation, single-administration instructions directed respondents to estimatetypical mood over a period of time that coincided with the time and duration of the multiple administrations. Subjects rated mood states during two single-administration settings, one before and one just after a multiple administration period. For both single-administration assessments, subjects rated mood relative to “How you have felt for the past 3 days, including today?” During the multiple-administration assessment, subjects rated mood six times a day for 3 days as prompted by preprogrammed wrist monitors. Results were consistent with earlier findings by identifying the bias in single-administration assessments. Initial single-administration values were significantly higher than both the averaged multiple-administration values and the second single-administration scores. These results support the contention that single-administration values from the POMS may provide biased estimates oftypical mood states.     

Retrieval-induced forgetting in an eyewitness-memory paradigm

The potential impact of repeated questioning of a witness was examined. Subjects were shown slides depicting the aftermath of a theft and subsequently were asked several times to recall selected details of what they saw. Previous experiments employing simple verbal materials have demonstrated that information addressed by questioning becomes more recallable in the future than it would have been without such retrieval practice, but other information, especially that bearing a categorical similarity to the practiced items, becomes less recallable. Such positive and negative effects appeared in subjects’ later recall of crime-scene details in the present experiment. These results have an important implication for legal practice: Repeated interrogation of a witness can modify the witness’s memory-enhancing the recall of certain details while inducing the forgetting of other details-even when no misinformation is contained or implied in the questioning.     

Antecedent exercise as a treatment for disruptive behavior: Testing hypothesized mechanisms of action

This study evaluated the effects of antecedent physical exercise (AE) and a mastery task on behaviorally disturbed children's self-concepts and rates of disruptive behaviors. In addition, we evaluated whether changes in self-concept mediated any exercise induced changes in rates of disruptive behavior. Fifty-eight children were randomly assigned to one of three conditions: (a) antecedent exercise (jog/walk), (b) “mastery” task (a successive improvement miniaturebasketball shooting task), and (c) no treatment control group. A week of baseline was followed by 4 weeks of treatment and, finally another week of return to baseline. Results indicated that: (a) AE produced significantly less disruptive behavior than no treatment, (b) the “Mastery” task did not produce significantly less disruptive behavior than no treatment, (c) neither treatment produced increases in self-concept relative to no treatment, and (d) changes in self-concept did not mediate AE induced reductions in disruptive behaviors.     

INCREASING RECYCLING IN ACADEMIC BUILDINGS: A SYSTEMATIC REPLICATION

We placed recycling receptacles in two locations in academic buildings and studied recycling behavior within an ABA multiple baseline design. During baseline, recycling receptacles were placed in a central location. During the intervention, receptacles were moved into classrooms where beverages were primarily consumed. Baseline conditions were then reinstated. The percentage of cans recycled daily increased during intervention and returned to near-baseline levels during withdrawal. The percentage of cans discarded daily in the trash decreased during the intervention and increased to near-baseline levels during withdrawal. Implications of this study include making recycling more convenient in institutional settings.     

An automatic micropipette fluid dispenser

An automatic device for repeated dispensation of a precisely controlled amount of fluid is described. The device employs a repeating micropipette powered by an electric motor geared to a rack-and-pinion drive. In our particular application, thirsty rats work for 0.2-ml shots of water delivered to a metal spout connected to a drinkometer circuit. This arrangement permits the recording of both volumetric intake and the number of licks directed at the spout.     

Effect of field size, head motion, and rotational velocity on roll vection and illusory self-tilt in a tumbling room

The effect of field size, velocity, and visual fixation upon the perception of self-body rotation and tilt was examined in a rotating furnished room. Subjects sat in a stationary chair in the furnished room which could be rotated about the body roll axis. For full-field conditions, complete 360 degrees body rotation (tumbling) was the most common sensation (felt by 80% of subjects). Constant tilt or partial tumbling (less than 360 degrees rotation) occurred more frequently with a small field of view (20 deg). The number of subjects who experienced complete tumbling increased with increases in field of view and room velocity (for velocities between 15 and 30 degrees s-1). The speed of perceived self-rotation relative to room rotation also increased with increasing field of view.     

Persuasive Impact of Organizational Value Statements in a Recruitment Context1

Two experiments were conducted to examine the persuasive impact of different types of evidence supporting an organizational recruitment message. In the first experiment, information on organizational values, presented in a recruitment brochure, was supported using statistical, anecdotal, or no evidence. Graduating university students who were attending a job fair (N = 69) were most attracted to the company as an employer when statistical evidence was presented. In the second study, an employed sample (N= 172) received organizational value evidence in the context of either a recruitment brochure or a community newspaper article. Whereas we replicated the findings of the first study in the brochure condition, we found that anecdotal information was most persuasive in the newspaper condition. We conclude that predicting the persuasive impact of evidence for organizational values requires knowledge of both the type of evidence to be employed and the medium in which that evidence is conveyed.     

Expectant adolescent couples' relations and subsequent parenting behavior

The goal of this study was to test the “spill over” hypothesis—that the quality of relations between expectant couples would predict parenting behavior—among a sample of adolescent mothers and fathers. At Time 1, self‐reported and observational relationship data were collected from 36 expectant adolescent couples. At follow‐up, observational data were collected from both young mothers and fathers who were asked to participate in a structured play activity with their 2‐year‐old children. Logistic and multiple regression analyses were run to examine the correspondence between couples' relationship quality prior to the childbirth and subsequent relationship status (i.e., paternal disengagement or coparenting) and the quality of parenting behavior. Results generally supported the spill over hypothesis. More specifically, findings indicated that the quality of the expectant mother's behavior toward her partner predicted his (paternal) behavior at follow‐up. Couples who reported high positive relations at the prenatal assessment were more likely to remain involved in coparenting. Results underscore the relevance of couples' relations to the development of positive parenting practices among atypical samples of mothers and fathers.     

The Relational Health Indices: A Study of Women's Relationships

A new measure of women's relationships, the Relational Health Indices (RHI), comprises three scales that assess growth-fostering connections with peers, mentors, and communities. The RHI was developed using the Relational Model (Jordan, Kaplan, Miller, Stiver, Surrey, 1991; Miller & Stiver, 1997), a theory of women's psychological development. The 37-item measure assesses three conceptual dimensions of growth-fostering relationships: engagement, authenticity, and empowerment/zest. This study examined the psychometric properties of the RHI with a group of 450 students at a women's liberal arts college, providing evidence for the reliability, validity, and utility of the new measure. The factor analyses confirmed a three-subscale structure: engagement, authenticity, empowerment/zest. The RHI's components generally demonstrate good overall internal consistency. Furthermore, associations between RHI scales and convergent validation scales were significant and in the direction hypothesized. Correlations with adjustment scales varied across the RHI components. The RHI has potential for enriching our understanding of important, subtle qualities and complex dynamics of both dyadic and group relationships, especially among women. The instrument is available for use by researchers interested in continuing the scale and theory development.
