Least squares metric,unidimensional scaling of multivariate linear models

The squared error loss function for the unidimensional metric scaling problem has a special geometry. It is possible to efficiently find the global minimum for every coordinate conditioned on every other coordinate being held fixed. This approach is generalized to the case in which the coordinates are polynomial functions of exogenous variables. The algorithms shown in the paper are linear in the number of parameters. They always descend and, at convergence, every coefficient of every polynomial is at its global minimum conditioned on every other parameter being held fixed. Convergence is very rapid and Monte Carlo tests show the basic procedure almost always converges to the overall global minimum.The author thanks Ivo Molenaar, three anonymous referees, and Howard Rosenthal for their many helpful comments.     

Determining career orientations in women from different social-class backgrounds

This study examines career orientations in women from high- and low-socioeconomic status backgrounds, using a longitudinal data set collected over a period of 10 years, from 1973 to 1982. When first contacted, respondents were 18 years of age. The final data collection in 1982 resulted in a sample of some 1300 women. The longitudinal data were analyzed using LISREL structural equation modeling and were guided by a theoretical framework developed by Krumboltz (1981) which focuses on the process of decision-making. Results from the study indicated that there were effects of social-class background in the development of women's career orientations, over the secondary school-early career development stage. Group differences in determinants of orientation were found for political attitudes, occupational interests, senior school achievement, and professional attainment. Differences were also found in the influence of motivational tendencies and work satisfaction on model variables for the two groups of women. The benefit of the decision-making theoretical framework and its further development for use in studies of career development generally are discussed.     

Gender-Related Knowledge Variations Within Geography

In a survey of students from junior high through the undergraduate college level, males consistently out-performed females on a test covering map skills and physical, human, and regional aspects of geography. The gender gap was consistent across all four subfields. It widened with increased education and was significant even after accounting for numerous personal information items that might have explained the difference. This consistent performance difference involving the broad spectrum of geographic knowledge argues against explaining the gender gap as symptomatic of differences in a single underlying factor such as map skills or spatial abilities. Knowledge-based and nonknowledge-based explanations for the gender difference are discussed.     

Individualized services and supports through the wraparound process: Philosophy and procedures

The wraparound process is emerging as an alternative to the traditional treatment planning processes inherent in categorical services for children and adolescents with emotional and behavioral disorders. We describe the current practices which have been developed in the field. Key elements of the value and philosophical base for the wraparound process are discussed. Proposed procedural steps are described to aid communities in the implementation of the wraparound process. Due to social and policy pressures, it is likely that wraparound process implementations will continue to develop.     

Underprediction of Female Performance from Standardized Knowledge Tests: A Further Example from the Knowledge of Geography Test

It has been documented that some tests ofbackground knowledge underpredict the performance offemale students in college. This study explored whetherthe underprediction phenomenon would also be found for a test that tapped four subfields ofgeography. Students (primarily White, N = 315) enrolledin nine geography classes at a comprehensive, midwesternuniversity completed the Knowledge of Geography (KOG) test during the first week of the semester andconsented to release their first exam grades, finalgrades, and ACT scores. Replicating a previous study(Henrie, Aron, Nelson, & Poole, 1997), there were gender differences favoring males across allfour subfields of the KOG test. KOG test scorescorrelated with grades, but males and females achievedcomparable course grades despite the lower performance of females on the KOG test. Examples illustratehow small differences between predicted and actualgrades can translate into large gender discrepancieswhenever minimum scores from tests that underpredict the performance of a subgroup are used toqualify students for educationalopportunities.     

Comments on Research in Family Therapy

This comment is submitted with the intent of stimulating some exchange between researchers. Although I chose the Woodward et al. study as a vehicle for my statement, I might easily have chosen examples outside the family therapy area.     

The relationship of GMA to counterproductive work behavior revisited

Recent research reported that general mental ability (GMA) predicted counterproductive work behavior (CWB), whereas some previous studies failed to find such a relationship. We tested occupational homogeneity of the sample and criterion measurement as two potential explanations for these inconsistencies. Study 1 replicated major design features of one previous study, which found no GMA–CWB relation in a heterogeneous sample, with occupationally homogeneous groups. Results confirmed previous null findings, indicating no effect of sample homogeneity. In Study 2, using a controlled laboratory setting, GMA was again unrelated to self‐reported CWB, but partially predicted observed CWB negatively. Combined findings suggest that GMA is consistently unrelated to CWB self‐reports but may predict objectively measured CWB independently of the likelihood of being caught.

Effects of neonatal cyproterone acetate administration on isolation-induced fighting behavior and mounting behavior in male and female TO strain albino mice

The effects of a single dose (1 mg) of cyproterone acetate administered on either day 1 or day 20 of life on the adult behaviors of male and female TO strain albino mice were studied. The mice were tested both in a “standard opponent”-type situation and in a similar test using a hormonally primed receptive female, after being gonadectomized and maintained with testosterone propionate as adults. Neonatal treatment with this compound had little effect on subsequent fighting behavior in either sex, but clear evidence was produced that this treatment masculinized the sexual behavioral potentialities of the females, an effect which was apparent in animals which had been injected on either day 1 or day 20 of life. Indications were obtained that females treated neonatally with cyproterone acetate were capable of differentiating between the male and female “opponents” in a manner similar to the male. The effects of this treatment on fighting behavior consequently appear to be dissimilar to the effects of neonatal castration in this species. However, the effects on mounting behavior in the females, evidenced in adulthood, seem Likely to be a consequence of the weak androgenic properties of the antiandrogen. The administration of cyproterone acetate neonatally appears to have a more dramatic effect on the adult weights of endocrine organs in females than in mates.
