Partible paternity, the conception belief that more than one man can contribute to the formation of a fetus, is common in lowland South America and characterized by nonexclusive mating relationships and various institutionalized forms of recognition and investment by multiple cofathers. Previous work has emphasized the fitness benefits for women where partible paternity beliefs facilitate pater...

Although it has been hypothesized that culture and religion play an important role in sexuality, the relative roles of acculturation and religiosity on ethnic differences in sexual attitudes have not been often empirically explored. The present study assessed differences in sexual attitudes in Euro-American, Asian, and Hispanic American populations using measures of acculturation to analyze the...

INTRODUCTION Intracranial needles are rare entities. Intracranial foreign bodies due to non-missile intracranial penetrations are one of the most rarely encountered situations in neurosurgery. Sewing needles are among the more unusual foreign bodies that may be found in the brain. Although uncommon, foreign body cases are important and interesting. Foreign bodies enter the body through trauma o...

This study, carried out during the second half of 1995, investigated the predisposing factors leading to marital disruption and its consequences on the lives of women in Matlab, a rural area of Bangladesh. Both qualitative and quantitative methods were used. Data were generated from detailed case studies and quantitative surveys of a small number of maritally-disrupted women. Additional data we...

Data on gender roles, perceptions of types of sexual relationships, perceptions of persons with STDs, and STD patient experiences were gathered through in-depth interviews ...

This article suggests very simple three-step estimators for censored quantile regression models with a separation restriction on the censoring probability. The estimators are theoretically attractive (i.e., asymptotically as efŽ cient as the celebrated Powell’s censored least absolute deviation estimator). At the same time, they are conceptually simple and have trivial computational expenses. T...

a r t i c l e i n f o People often aspire for true love and committed romantic relationships. These relationships, however, are recurrently threatened by partner infidelity. The present research tested a new infidelity-detection model, the rivalry sensitivity hypothesis, that posits that women are more sensitive to cues of infidelity than men are, and tend to focus their attention on potential ...

al monogamy4 and covert sex outside the main relationship. Delayed marriage and high divorce rates mean that growing numbers of individuals experience multiple sexual partners in a lifetime, and this greatly increases their exposure to infection. Furthermore, National Health and Social Life Survey data show that around 25% of men and 10% of women report extramarital or extracohabitational affai...
