An analysis of factors affecting traditional family expectations and perceptions of ideal fertility

This study examines: 1) the conditions giving rise to variation in sex-role orientation and the perceived cost of having children; and 2) the role these variables play as mechanisms linking antecedent variables to perceptions of ideal fertility. Data are drawn from a metropolitan area (Oklahoma City) sampling of 401 adults. Antecedent variables of sex, employment status, age, education, exposure to metropolitan living, and religious traditionalism--though correlated with ideal fertility--have no direct effects on that variable. Rather, the effects of these variables on fertility are mediated through sex-role orientation and the perceived cost of having children. The study confirms that there is a great deal of variation in the perception of a woman's place in comtemporary society and much of this variation is predictable. Education and exposure to metropolitan living both have influences which result in more egalitarian sex-role orientations, while traditional beliefs reinforce traditional sex-role orientations. Younger people also are more likely than older ones to be egalitarian. On the average, women are less traditional in their sex-role orientations than men and employed women are less traditional than unemployed women. Thus, the 2 strongest predictors of sex-role orientation are age and education. Sex role orientation and the perceived cost of having children both exert strong influences on the number of children thought to be ideal.     

A new procedure for detection of crossing DIF

The purpose of this paper is to present a hypothesis testing and estimation procedure, Crossing SIBTEST, for detecting crossing DIF. Crossing DIF exists when the difference in the probabilities of a correct answer for the two examinee groups changes signs as ability level is varied. In item response theory terms, crossing DIF is indicated by two crossing item characteristic curves. Our new procedure, denoted as Crossing SIBTEST, first estimates the matching subtest score at which crossing occurs using least squares regression analysis. A Crossing SIBTEST statistic then is used to test the hypothesis of crossing DIF. The performance of Crossing SIBTEST is evaluated in this study.This research was partially supported by a grant from the Law School Admission Council and by National Science Foundation Mathematics Grant NSF-DMS-94-04327.

Survival skills and ethics training for graduate students: A graduate student perspective

Graduate students in the sciences must develop practical skills geared toward scientific survival and success. This is particularly true now, given the paucity of research funds and jobs. Along with more elementary skills, research ethics should be an integral part of students’ scientific training. Survival skills include research skills, communication skills, general efficiency, and preparation for post-graduate work. Ethics training covers guidelines for use of animal and human subjects, data treatment, disclosure, credit issues, conflicts of interest, and response to misconduct. The objective of this paper is to describe, from a graduate student’s perspective, the need for survival and ethics training in graduate programs and to raise both faculty and student awareness of the possibilities for explicit instruction of these skills. Many survival skills and ethical practices will be learned without explicit direction and some are already part of standard training; but, this is not the case for all students or for all skills, so specific instruction is a necessity. Research faculty can use their own experience to help students to develop the proficiencies they will need to succeed.     

Estimating the impact of variable costs on SDy in complex situations

The inclusion of variable costs when estimating the standard deviation of job performance in dollars has been the basis for a number of highly important advances in utility analysis (e.g. Boudreau, 1983; Boudreau & Berger, 1985). However, no studies have shown the feasibility of incorporating variable costs in situations where multiple types of costs might require global estimation of variable costs. Results obtained from a nationwide sample of insurance personnel indicated that global estimates of variable costs were feasible to obtain in such complex situations but that those costs were not a fixed percentage of the value of job performance. Judges reported that the most important inputs of information into their estimates of the value of job performance in dollars were performance and output as well as initiative of the job holder. Surprisingly, salary related information was not reported as a relatively important input.The authors wish to thank Patricia G. Roth, Bart Osburn, and Jim Phillips for reviewing previous drafts of this work and contributing their valuable comments. The paper has improved as a result of their insights.

A model-based standardization approach that separates true bias/DIF from group ability differences and detects test bias/DTF as well as item bias/DIF

A model-based modification (SIBTEST) of the standardization index based upon a multidimensional IRT bias modeling approach is presented that detects and estimates DIF or item bias simultaneously for several items. A distinction between DIF and bias is proposed. SIBTEST detects bias/DIF without the usual Type 1 error inflation due to group target ability differences. In simulations, SIBTEST performs comparably to Mantel-Haenszel for the one item case. SIBTEST investigates bias/DIF for several items at the test score level (multiple item DIF called differential test functioning: DTF), thereby allowing the study of test bias/DIF, in particular bias/DIF amplification or cancellation and the cognitive bases for bias/DIF.This research was partially supported by Office of Naval Research Cognitive and Neural Sciences Grant N0014-90-J-1940, 4421-548 and National Science Foundation Mathematics Grant NSF-DMS-91-01436.

Identification of gifted deaf children: a complex but critical educational process.

11 deaf students in a large midwestern school for the deaf were divided into gifted and nongifted groups by ratings of teachers and school administrators. There were six subjects in the gifted group (3 boys and 3 girls) and five subjects in the comparison group (3 boys and 2 girls). There was no statistically significant difference between mean raw scores of the two groups on Raven's Advanced Progressive Matrices. Also, teachers' rankings of the subjects identified as gifted did not correlate significantly with their Raven scores. Identification of gifted deaf students is too complex to be based only on teachers' ratings.     

The role of trainee knowledge structures in aviation team environments

The importance of having well-developed knowledge structures to enhance complex team performance has been recently indicated in the training effectiveness literature. This work tested that proposition within an aviation team training setting. Results suggested that aviation team training improved the knowledge structures of those participants who received the training. Knowledge structure data also provided information related to the training that was not available from more traditional measures of learning. Finally, results obtained from the knowledge structure measures were consistent with performance results, suggesting that knowledge structure measures are a potentially valid predictor of performance.     

Comparison of decision learning models using the generalization criterion method

It is a hallmark of a good model to make accurate a priori predictions to new conditions ( Busemeyer & Wang, 2000 ). This study compared 8 decision learning models with respect to their generalizability. Participants performed 2 tasks (the Iowa Gambling Task and the Soochow Gambling Task), and each model made a priori predictions by estimating the parameters for each participant from 1 task and using those same parameters to predict on the other task. Three methods were used to evaluate the models at the individual level of analysis. The first method used a post hoc fit criterion, the second method used a generalization criterion for short-term predictions, and the third method again used a generalization criterion for long-term predictions. The results suggest that the models with the prospect utility function can make generalizable predictions to new conditions, and different learning models are needed for making short-versus long-term predictions on simple gambling tasks.     

For-profit/nonprofit differences in center-based child care quality: Results from the National Institute of Child Health and Human Development Study of Early Child Care and Youth Development

In secondary analyses of National Institute of Child Health and Human Development Study of Early Child Care and Youth Development data, multiple indicators of quality (caregiver wages and turnover; child/staff ratio; caregiver education and professionalism; positive caregiving) were compared between child care centers by sector (for-profit/nonprofit) and subsector (for-profit independent/chain, nonprofit church/nonchurch) at multiple points from infancy through prekindergarten. Nonprofit centers evidenced higher caregiver wages and education at most ages and better quality child/staff ratios, turnover, caregiver professionalism, and positive caregiving for toddlers and preschoolers. Subsector differences in preschool classrooms were more complex. In general, quality was higher in nonprofit non-religiously affiliated centers, intermediate in nonprofit religiously affiliated and for-profit independent centers, and lower in for-profit chains, but differences were not found on every indicator or between every group. Further, for-profit chain status predicted lower quality positive caregiving, controlling for family characteristics, staff, and structural quality, at 54 months, but not 36 months. Results support and extend prior research by controlling for family characteristics. Policy implications regarding supply- and demand-side quality-improvement strategies that address market competition and parent choice across subsectors are discussed.
