Public transit wage rates: Pre-Reagan and Reagan-Bush eras

This paper examines the earnings of public transit bus drivers for both the pre-Reagan and Reagan-Bush eras using Current Population Survey data. The findings show that union drivers were consistently paid a significant wage premium over nonunion drivers, a premium which also exceeded that for unionized private nontransport operatives — suggesting that special institutional features of the public transit industry have collectively conferred market power on unionized public transit workers. During the Reagan years, the earnings of public transit drivers, union and nonunion alike, rose relative to those of private and public nontransport operatives in spite of federally-spearheaded cost containment policies. In 1990, these earnings fell relative to those of private and public nontransport operatives, suggesting that the effects of these policies may be beginning to be felt.

Analysis of the reliability of a new scale for housing quality

This article reports the results of a variance components investigation of the reliability of a new scale of measurement of the quality of a dwelling unit. A balanced incomplete block design was utilized. A method for selecting among competing unbiased estimators of the variance components is presented. These components furnish a measure of the stability of the new dwelling quality scale. The validity of this new scale was investigated by comparison with experienced housing inspectors' reports.     

Ethnicity-of-Interviewer Effects Among Mexican-Americans and Anglos

A general interpersonal deference explanation for ethnicity-of-interviewereffects is tested with a random survey of Anglos and Mexican-Americansusing Anglo and Hispanic interviewers and questions relatedto Mexican-American culture. The theory was most clearly supportedamong Anglo respondents. The mixed support found among Mexican-Americanssuggests that deference is strongest when questions deal withthe culture represented by the interviewer, not the respondent.     

The benefits of a nap during prolonged work and wakefulness

Prolonged work scenarios with demands for sustained performance are increasingly common. Because sleep loss inevitably compromises functioning in such situations, napping has been proposed as a countermeasure. The optimal timing of the nap relative to its benefits for performance and mood is not known, however. To address this issue, 41 healthy adults were permitted a two-hour nap at one of five times during a 56-hour period of intermittent work, with no other sleep. Naps were placed 12 hours apart, near the circadian peak (P) or trough (T), and were preceded by 6(P), 18(T), 30(P), 42(T), or 54(P) hours of wakefulness. Work test bouts occurred every few hours and consisted of a variety of psychomotor and cognitive tasks as well as mood scales completed at the beginning, middle and end of each bout. A total of eight performance and 24 mood parameters were derived from the bouts and compared between groups at all test points prior to and following the naps. An estimate of the extent to which each nap condition differed from the control (P54) condition was derived by totalling the proportion of test points that yielded statistically significant results relative to the total number of tests conducted both before and after naps.

Although all performance and most mood parameters displayed a circadian-modulated deterioration as the protocol progressed, a nap appeared to attentuate the extent of this change in all performance parameters but not in mood parameters. Overall, the timing of the nap across days and within the circadian cycle was irrelevant to its effect on performance, suggesting that it diminished the intrusion of sleepiness into behavioural functioning, even though subjects were phenomenally unaware of this benefit.     

A Curriculum for Graduate-Level Marriage and Family Therapy Education*

The Delphi technique of refining group opinion was used to develop a graduate level marriage and family therapy curriculum. Opinions were synthesized from a national panel of 20 AAMFT Approved Supervisors and 25 training directors of graduate-level marriage and family therapy programs. Three rounds of questionnaires were employed and 101 content areas met the criteria for inclusion into the final curriculum. Discussed are the similarities and differences of this curriculum and the current “model” AAMFT curriculum. It is hoped that the curriculum devised from this study will lead to the continued rethinking, refinement, and evolution of marriage and family therapy education.     

From probation to prevention: protecting college students and workers from animal hazards

OBJECTIVE: Our objective was to develop an organized system to assess individual and group exposure to animal hazards on a college campus. MAIN POINTS: The scope and complexity of college health services continue to expand as campuses confront unforeseen exposures and disease entities. Of great concern are students and faculty who are exposed to potentially life threatening and other serious conditions during their academic work. CONCLUSION: A college health service developed an effective animal-hazard surveillance questionnaire that could be scanned and analyzed for individual and group exposure to hazards and the presence or absence of protective measures. The college then provided appropriate preventive services.     

The role of social work in the ICU: reducing family distress and facilitating end-of-life decision-making

The costs associated with Intensive Care Units (ICUs) are high and at times invasive ICU care may not be beneficial, particularly for those patients admitted to ICUs who have little hope of recovery. The process of clarifying medical goals for these patients is often facilitated by addressing psychosocial factors. Social workers in the ICU are uniquely qualified to assess and address many of the complex psychosocial circumstances and can clarify potential misperceptions, enhancing communication among patients (if capacitated), their families, and the medical team members. This can not only help improve quality of life for very sick and dying patients in the ICU and their families, but may also reduce the likelihood of decision-making conflicts from arising. Further studies need to be done to investigate the effectiveness of social work interventions in reducing family distress, avoiding care that is unwanted by patients, and demonstrating cost-saving benefits.     

Comment

We propose a sequential test for predictive ability for recursively assessing whether some economic variables have explanatory content for another variable. In the forecasting literature it is common to assess predictive ability by using “one-shot” tests at each estimation period. We show that this practice leads to size distortions, selects overfitted models and provides spurious evidence of in-sample predictive ability, and may lower the forecast accuracy of the model selected by the test. The usefulness of the proposed test is shown in well-known empirical applications to the real-time predictive content of money for output and the selection between linear and nonlinear models.
