GENERALIZED INVERSES USED IN RECURSIVE ESTIMATION OF THE GENERAL LINEAR MODEL1

Recursive methods in regression have proved useful in providing diagnostic tools for checking the model as well as checking the stability of the model over time. Such methods are now extended to deal with the problems of singularity that arise when one variable is completely confounded with previously fitted variables up to a particular time point. The problem is solved by setting it in the framework of the general linear model with dependent errors.     

The effects of fatal vision goggles on drinking and driving intentions in college students

The present study was designed to examine the effectiveness of Fatal Vision Goggles in reducing intentions to drink and drive. Participants performed a field sobriety task and drove in a traffic simulator while wearing the goggles. A regression analysis was performed in order to predict changes in intentions to drink and drive, using typical drinking patterns, perceived likelihood of getting into a collision when drinking and driving, self efficacy, and driving independence as predictor variables. Results showed that drinking and driving intentions were reduced following the use of Fatal Vision Goggles among those that typically drink more during outings, among those that believe the likelihood of collisions when drinking and driving are greater, and among those less likely to drive to achieve independence and autonomy. These results indicate that Fatal Vision Goggles can be an effective tool in altering drinking and driving attitudes among drivers with specific attitudinal and personal characteristics.     

Perceptions of physical restraint use and barriers to restraint reduction in a long-term care facility

The use of restraints in nursing homes has been curtailed in the United States since the passage of the 1987 federal legislation regulating restraint practices. This study used focus groups with administrators and nursing staff in a skilled nursing facility to examine their views of restraints and perceptions of conditions in the nursing home environment that affect restraint use. Although respondents lacked a shared definition of a "restraint," they did identify contextual factors that in combination with resident characteristics produced situations in which restraint use was justified. Implications of these findings for staff education on restraint reduction are discussed.     

Assimilation or exclusion? Japanese and Mexican Americans in California

This paper argues that the current socioeconomic positions of ethnic groups reflect in part the historical processes that differentially allocated labor market opportunities by ethnicity. With historical and current data, we illustrate the usefulness of this approach by investigating two ethnic groups at opposite ends of the socioeconomic spectrum—native-born Japanese and Mexican American men and women in California. We first document the structural context facing these two immigrant groups when they entered the U.S., describing how early experiences shaped their occupational concentrations. Using 1980 Census data we then show how the current occupational distributions of these ethnic groups resemble those of their immigrant ancestors, and how this occupational concentration now affects earnings attainment, relative to whites. The evidence on gender differences suggests caution in generalizing from the experiences of male ethnics—the occupational and earnings attainments of female ethnics differ notably from those of their male counterparts.     

Estimating the Longitudinal Association Between Adolescent Sexual Behavior and Exposure to Sexual Media Content

The purpose of this study is to estimate the association between adolescent sexual behavior and exposure to sexual media content. A three-wave, longitudinal survey sample (N = 506) of 14- to 16-year-olds at baseline is analyzed using growth curves. Growth trajectories are linear for sexual behavior but not for exposure to sexual media content. The signs of the exposure slopes are not uniformly positive: Hispanic and African American respondents show declines of exposure to sexual media content over the age range investigated here. Although changes in exposure to sex content are highly associated with changes in sexual behavior among Whites, there is little or no association between changes in these variables among Blacks.     

Identifying the Causal Pathways from Religiosity to Delayed Adolescent Sexual Behavior

This study used the Integrative Model as a framework to examine whether religiosity delays onset of coitus among a longitudinal sample of virgins, and investigated the causal pathways of this relationship. In addition, this study examined the behavioral beliefs about the consequences of engaging in sex, which distinguishes between youth who vary in level of religiosity. A further analysis was also conducted to examine whether religiosity offers protective effects in terms of progression toward sexual intercourse on a sexual behavior index. The sexual behavior index assumes a progressive nature of sexual behaviors, and includes the following seven behaviors: kissing, having breasts touched (touching for boys), genital touching, receiving oral sex, vaginal intercourse, giving oral sex, and receiving (or giving) anal sex. Religiosity at baseline was negatively associated with sexual debut one year later. This relationship was mediated through attitudes toward personally engaging in sexual intercourse. Religiosity at baseline was also negatively associated with scores on the sexual behavior index one year later. These results suggest that religiosity offers protective effects for both coital and noncoital sexual behaviors.     

Evaluation of a Goal Orientation Model of Vocational Identity

The authors tested a model that considered goal orientation (mastery approach, performance approach, and performance avoidance) as an antecedent to vocational identity (career exploration and commitment) and included both career behaviors (career‐related strategies) and affect (career distress) as outcomes of vocational identity. The authors also assessed vocational identity as a mediator for consistency with models of career development. The study was survey based with 281 young adult participants (77% women, mean age = 26 years). Mastery and performance approach were associated with more career exploration, which, in turn, was associated with greater use of career‐related strategies. Performance avoidance was associated with more career commitment, which was then related to greater distress. The study demonstrated that goal orientation is a potentially important antecedent to vocational identity, which has implications for how practitioners work with young adults with different goal orientations.     

“Aging males” symptoms and general health of adult males: a cross-sectional study

A cross-sectional study was conducted to explore the prevalence and severity of health-related complaints perceived by adult males of Hong Kong by using the Hong Kong Traditional Chinese versions of the Aging males’ symptoms (AMS) scale and the 5-dimensional and 3-level European Quality of life (EQ-5D-3L) questionnaire. A total of 825 adult males aged 40 years or above were surveyed, and observed that 80% of the population was living with little-to-mild levels of aging symptoms with mean total scores ranged between 26.02?±?7.91 and 32.99?±?7.91 in different age groups. Such symptoms were correlated with age, especially for the somato-vegetative and sexual symptoms. The most severe AMS symptoms were observed in the oldest age group at 70 years or above, with 76%, 34% and 70% living with moderate-to-severe levels of somato-vegetative, psychological and sexual symptoms, respectively. The result was highly correlated with the EQ-5D-3L questionnaire. Secondly, the Hong Kong Aging males’ symptoms (AMS) scale was shown to have good reliability with test–retest coefficient at 0.79 (ranged 0.66–0.87) and Cronbach’s alpha coefficient at 0.88 (ranged 0.70–0.84). In summary, the population of Hong Kong male adults was commonly living with little-to-mild levels of aging symptoms, whereas their severity was correlated with age.     

Low‐income and Middle‐class Mothers Gendered Work and Family Schemas

Conflict between the demands of paid work and motherhood has been studied primarily from the experience of middle‐class and professional mothers in dual‐earner families. Recently, with the reform of welfare, a number of studies have focused on the problems of poor mothers in meeting the demands of paid employment and caring for children. This article explores the moral discourse of judgments about paid work and motherhood and how this differs for low‐income and married middle‐class women. It reviews research that considers why poor single mothers are seen as irresponsible when they leave work due to family demands when professional and middle‐class married mothers are seen as acting selflessly. It examines how gendered schema differentially influences the work and family choices of married middle‐class and professional mothers compared to poor and low‐income mothers.
