Parenting in later life: Adaptive illusion in elderly mothers of one child

This article explores (1) the relationship between elderly mothers of one child and their son or daughter and (2) the impact of that relationship on mothers' current and future well-being. Data from ethnographic interviews of twenty mothers of one, and twenty mothers of four or more children were compared for thematic content. Mothers of only children were found to be child-focused to the exclusion of other life-enriching activities, and singularly dependent on their son or daughter for self-validation. Significant in the interview material of single-childed mothers was the use of illusion as a tool for defusing disappointment in, or fabricating closeness to the child.     

Mesothelioma Among Brake Mechanics: An Expanded Analysis of a Case-Control Study

The U.S. Environmental Protection Agency has begun discussions to consider its assessment of asbestos toxicity related to mineral form and fiber size. Brake workers are typically exposed to short chrysotile fibers. To explore the mesothelioma risk among brake workers, considering other occupational exposures to asbestos, data from a study that was published previously were obtained and the analysis was extended. The National Cancer Institute provided data from a case-control study of mesothelioma. Because many participants with a history of brake work also had employment in other asbestos-related occupations, mesothelioma cases and controls were compared for a history of brake work, controlling for employment in eight occupations with potential asbestos exposure. A stratified analysis was also performed excluding those with any of the eight occupations. Possible interactions between brake work and other occupational exposures related to risk of mesothelioma were also examined. The odds ratio (OR) for employment in brake installation or repair was 0.71 (95% CI: 0.30-1.60) when controlled for insulation or shipbuilding. When a history of employment in any of the eight occupations with potential asbestos exposure was controlled, the OR was 0.82 (95% CI: 0.36-1.80). ORs did not increase with increasing duration of brake work. Exclusion of those with any of the eight exposures resulted in an OR of 0.62 (95% CI: 0.01-4.71) for occupational brake work. There was no evidence of an interaction between brake work and other occupational exposures. These latter analyses were based on small numbers of exposed cases. The results are consistent with the existing literature indicating that brake work does not increase the risk of mesothelioma and adds to the evidence that fiber type and size are important determinants of mesothelioma risk.     

Paternal Work Stress and Latent Profiles of Father–Infant Parenting Quality

The current study used latent profile analysis (LPA) to examine the implications of fathers' experiences of work stress for paternal behaviors with infants across multiple dimensions of parenting in a sample of fathers living in nonmetropolitan communities (N = 492). LPA revealed five classes of fathers based on levels of social–affective behaviors and linguistic stimulation measured during two father–infant interactions. Multinomial logistic regression analyses suggested that a less supportive work environment was associated with fathers' membership in multiple lower quality parenting classes. Greater work pressure and a nonstandard work schedule also predicted fathers' membership in the latent parenting classes, although these associations differed depending on the number of hours fathers spent in the workplace.     

Toward relationship-based child welfare services

A relationship-based theoretical framework for child welfare services is proposed. Research literature is reviewed relative to attachment theory, relationship quality of maltreated child-parent and maltreated child-surrogate parent dyads, and effective child-parent and child-surrogate parent relationship-enhancing interventions. Authors recommend that establishment or repair of a protective, emotionally responsive positive child-parent or child-surrogate parent relationship be the central focus of child welfare services. A model is offered as a conceptual foundation for measures to be used in federal Child and Family Services Reviews.     

Childhood Victimization,Cognitive Schemas,and Unwanted Consensual Sex Among College Students

Objective: Unwanted consensual sex (UCS)—freely consenting to sex that is neither wanted nor desired—is largely excluded from campus programming and the literature on sexual behavior. The present study expands on previous research to examine the relation between childhood victimization experiences and UCS.

Methods: Data were gathered using an online survey of college students.

Results: In the past year, 43% percent of 587 college students who engaged in sexual activity also engaged in UCS at least once. Childhood victimization was modestly related to frequency of UCS. The relation between childhood victimization and UCS was mediated by disconnection/rejection schemas (e.g., beliefs that one’s needs will not be met by others).

Conclusions: Results suggest that altering cognitive schemas through evidence-based psychotherapy may interrupt the relation between childhood victimization and engagement in UCS.     

Explicit Verbal Sexual Consent Communication: Effects of Gender,Relationship Status,and Type of Sexual Behavior

Objectives: College students believe that they are supposed to be explicit and verbal in their sexual consent communication. We examined various contexts to determine when sexual consent is likely to be communicated explicitly and verbally. Method: We surveyed U.S. college students’ (n?=?707) sexual consent communication. Results: We identified contexts when explicit verbal consent cues are less likely—when the person is a woman, when the sexual relationship is casual, and when the sexual behavior is not vaginal-penile intercourse. Conclusions: If sexual consent is contextual, that means communicating consent should not ever be taken for granted.     

Analysis of ordinal outcomes with longitudinal covariates subject to missingness

We propose a mixture model for data with an ordinal outcome and a longitudinal covariate that is subject to missingness. Data from a tailored telephone delivered, smoking cessation intervention for construction laborers are used to illustrate the method, which considers as an outcome a categorical measure of smoking cessation, and evaluates the effectiveness of the motivational telephone interviews on this outcome. We propose two model structures for the longitudinal covariate, for the case when the missing data are missing at random, and when the missing data mechanism is non-ignorable. A generalized EM algorithm is used to obtain maximum likelihood estimates.     

The Criteria for Open Access

Abstract

Each proposal for Open Access (OA) has its unique combination of features; each argument for or against OA focuses on particular features or criteria. This article is intended to discuss these criteria, both individually and also as each of them contributes to the different proposals for OA. Evaluation of the proposals themselves is not attempted. This discussion is intended to be of value to the supporters of OA, in choosing which plan to adopt, and to those opposed to OA, in showing where the weaknesses do and do not lie. In other words, this article intends to improve the level of factual understanding in the ongoing discussions.     

Fighting spam with statistics

Spam—unsolicited commercial e-mail—is a complex and growing problem, and threatens to derail the internet revolution. Joshua Goodman and David Heckerman of Microsoft Research describe some statistics-based methods for blocking spam, first by distinguishing it from wanted mail, and then by constructing puzzles they propose to use to challenge suspected spammers.
