Semiparametric linear transformation models for current status data

Current status data arise when the death of every subject in a study cannot be determined precisely, but is known only to have occurred before or after a random monitoring time. The authors discuss the analysis of such data under semiparametric linear transformation models for which they propose a general inference procedure based on estimating functions. They determine the properties of the estimates they propose for the regression parameters of the model and illustrate their technique using tumorigenicity data.     

Dimensions of occupational inequality and Duncan's socioeconomic index

Using the original 1962 Blau and Duncan data for white males, I compare relative amounts of inequality in the distributions of occupational prestige, earnings, autonomy, and job skills. Also assessed are the degree of status rigidity (or intercorrelations) among these four dimensions of occupational inequality and the simultaneous relations among these four dimensions in a father-to-son occupational mobility model. These findings are compared to those obtained with Duncan's socioeconomic index to determine whether additional information can be obtained when using independent measures representing the multiple dimensions of occupational inequality versus using the SEI alone. Only minor discrepancies are found, and these relate to autonomy and earnings.An earlier version of this paper was presented at the 1985 Pacific Sociological Association meetings.

Attitudes of Heterosexual Men and Women Toward HIV Negative and Positive Gay Men

Attitudes of Italian heterosexual men and women toward gay men, both HIV positive and negative, are poorly investigated. Italian culture is still extremely conservative and provides limited support to the gay community (e.g., lack of same-sex marriage recognition). Consequently, gay men experience social exclusion and disparities. The present study explores the association between homophobia and closeness with sexual orientation and HIV status. 261 heterosexual Italian men and women were assessed for feelings of closeness and homophobia after reading a vignette where the character was C1: heterosexual and HIV negative; C2: gay and HIV negative; or C3: gay and HIV positive. Experiences of homophobia and closeness varied depending on gender of participant and condition assigned, and higher levels of homophobia were correlated with lower levels of closeness regardless of HIV status. Implications and future directions are discussed.

Anti-N-methyl-D-aspartate receptor antibody encephalitis: An important cause of encephalitis in young adults. A report of two cases

Encephalitis is a clinical syndrome which can include altered mental status, motor and sensory deficits, altered behavior including personality changes, speech and movement disorders and seizures. While the overall incidence of encephalitis is not known, it is common enough that most pediatric and adolescent medicine physicians will have seen at least one case. Peak times of risk include the newborn period and middle-to-late adolescence.¹ Dalmau J, Tüzün E, Wu HY, et al. Paraneoplastic anti-N-methyl-D-aspartate receptor encephalitis associated with ovarian teratoma. Ann Neurol. 2007 Jan;61(1):25–36. doi:10.1002/ana.21050. PMID: 17262855.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar] It is important for clinicians to have a working knowledge of the broad range of encephalitis etiologies: viral, post-viral, toxic, auto-immune, and paraneoplastic. We discuss two cases of encephalitis in young adult women with ovarian teratoma and production of anti-N-methyl-D-aspartate receptor (NMDAR) antibodies.     

Acceptance and Caregiving of Married and Divorced Custodial Mothers and Fathers

The study examined whether differences in gender and family status affect parental caregiving disposition and acceptance of children among parents of children in mid-childhood. The number of participants were 122 divorced-custodial fathers, 107 married fathers, 85 divorced-custodial mothers, and 82 married mothers (n?=?398). A comparison among four groups of parents revealed the following gender differences: mothers scored higher on anxious caregiving and parental acceptance than fathers, and lower on avoidant caregiving. Regression analysis indicated that the higher the caregiving avoidance or anxiety, the lower the parental acceptance. Family status moderated parental acceptance, as avoidant caregiving was associated with reduced parental acceptance among married parents, but not among divorced custodial parents. The finding that avoidant caregiving was not associated with reduced acceptance among divorced custodial parents implies that their parental acceptance behaviors toward their children are affected by their parental status as sole custodial parent, and the associated responsibilities, rather than by gender.     

Joint models for mixed categorical outcomes: a study of HIV risk perception and disease status in Mozambique

Two types of bivariate models for categorical response variables are introduced to deal with special categories such as ‘unsure’ or ‘unknown’ in combination with other ordinal categories, while taking additional hierarchical data structures into account. The latter is achieved by the use of different covariance structures for a trivariate random effect. The models are applied to data from the INSIDA survey, where interest goes to the effect of covariates on the association between HIV risk perception (quadrinomial with an ‘unknown risk’ category) and HIV infection status (binary). The final model combines continuation-ratio with cumulative link logits for the risk perception, together with partly correlated and partly shared trivariate random effects for the household level. The results indicate that only age has a significant effect on the association between HIV risk perception and infection status. The proposed models may be useful in various fields of application such as social and biomedical sciences, epidemiology and public health.
