Parent‐to‐Child Aggression Among Asian American Parents: Culture,Context, and Vulnerability

We examined correlates of lifetime parent‐to‐child aggression in a representative sample of 1,293 Asian American parents. Correlates examined included nativity, indicators of acculturation, socioeconomic status, family climate, and stressors associated with minority status. Results revealed that Asian Americans of Chinese descent and those who immigrated as youth were more likely to report minor parental aggression; ethnicity and nativity were not associated with severe aggression. Indices of acculturation did not predict risk, but minority status stressors (perceived discrimination, low social standing) predicted risk of both minor and severe aggression. Affective climate differed markedly in families with minor versus severe aggression. Parental aggression in Asian American families may not be cultural per se, but stress associated with immigrant family context may heighten vulnerability.     

Unmet Needs for Assistance with ADLs and IADLs: A Measure of Healthy Life Expectancy

Measures of healthy life expectancy have beendeveloped over the last thirty years to evaluate thequality of life of an increasing life expectancy.These measures are usually accounting for prevalencerates of either disability or physical dependence inperforming everyday activities. Although they allowfor a better assessment of quality of life, they arenot reflecting the fact that a disabled person mightbe receiving adequate or inadequate assistance forthese activities. In a context of population aging,where our health care system will have to deal moreand more with chronic disease instead of acutedisease, it is imperative to develop a measure thatwill account for the adequacy of the assistanceprovided to the disabled elderly population. Usingdata from the 1986 Health and Activity LimitationSurvey, we are introducing a measure of healthy lifeexpectancy which will fill this gap. We present theconstruction of this measure of population health anddiscuss its usefulness in assessing policies at amacro level.     

Puerto Rican drug users experiences of physical and sexual abuse: comparisons based on sexual identities

This study integrates the results of quantitative and qualitative methods to elucidate the association between sexual identity and physical and sexual abuse among Puerto Rican drug users. A structured questionnaire was administered to 800 subjects in New York and 399 in Puerto Rico. A total of 93 subjects (7.9%) self-identified as homosexual or bisexual. Gay males were significantly more likely than heterosexual males to report first occurrence of physical abuse by a family member in childhood. Both gay and bisexual males were more likely than their heterosexual counterparts to report first experiencing unwanted sex in childhood and intimate partner physical abuse later in life. Lesbians were more likely than female heterosexuals to report unwanted sex in childhood. Qualitative data were collected through in-depth life histories with 21 subjects and suggest that gay and lesbian subjects perceive antihomosexual prejudice on the part of family members as one cause of childhood physical and sexual abuse.     

Clinical correlates and repetition of self-harming behaviors among female adolescent victims of sexual abuse

This study investigated self-harming behaviors in 149 female adolescent victims of sexual abuse, first, by determining the rates of nine types of self-mutilating behavior at intake and nine months later and, second, by investigating comorbidity of clinical correlates associated with these behaviors. The adolescents were divided into three groups according to level of self-mutilating behavior and then compared on symptom self-reports; 62.1% of the adolescents engaged in at least one self-mutilating behavior. A graded relation was observed between level of self-mutilating behavior and rate, and total number of clinical disorders. At nine month follow-up, one in four teenagers still reported a moderate or high level of self-harm. The need for systematic assessment and intervention of self-mutilating behaviors is discussed.     

Work and mental health: the experience of the Quebec workforce between 1987 and 1998

This study examines the distribution of psychological distress in twelve occupational groups over the decade 1987-1998 in the Quebec workforce. Cross-sectional data from the three phases of the Quebec Health and Social Survey are used with n = 9,450 in 1987, n = 10,947 in 1992 and n = 10,960 in 1998, totalling 31,357 workers aged 15 and over. Occupations are classified according to the Canadian Socio-economic Classification of Occupations. Prevalence estimates for occupational groups are computed and logistic regression analyses are conducted controlling for gender, age and marital status. The results show that the prevalence of workers with psychological distress increased sharply between 1987 and 1992 and declined back in 1998 but still increased compared to 1987. However, only non-qualified white collars, semi-qualified blue collars and male non-qualified blue collars show a significant increment in psychological distress over time. Analysis of the differentials in the prevalence of psychological distress gives greater odds of distress for supervisors, semi-qualified white and blue collar workers compared to upper managers. The odds for occupations are stable over time, gender, age and marital status. The odds of female workers significantly decreased in the three phases. It appears that the restructuring of the work environment and the perturbations in the larger society promoted an increase of psychological distress within definite segments of the workforce. The specific contribution of occupation is limited but supervisors and occupations requiring lower qualifications are more at risk regarding mental health at work.     

A functional data-analytic approach to the classification of species according to their spatial dispersion. Application to a marine macrobenthic community from the Bay of Morlaix (Western English Channel)

We investigate with multivariate methods the behaviour of species collected in a sequence of ecological surveys. The behaviour of the sth species is first characterized by a classical dispersion index. Under the hypothesis (H) of spatial randomness, the probability distribution v _s of this index obeys a reference law μ. All the sampled species are then compared through a Principal Components Analysis whose metric structure depends on μ. More precisely, the distance between two species s and s′ is an approximation of the μ-centred chi-square distance (Benzécri 1976 Benzécri, J. P. 1976. L'Analyse des Données, tome 2: L'Analyse des Correspondances, Paris: Dunod.  [Google Scholar]) between v _s and v _s′. Thus, while Correspondence Analysis displays departures from independence or homogeneity, the proposed analysis displays departures of the species from (H). As an application, a macrobenthic data time series is analysed, and the obtained species typology is described and discussed. The method enabled us to separate rare species from random ones while rare species could easily be confused with random ones. All the aggregated species were common (or even dominant), and most random ones were moderately abundant. Finally, a group of 23 species showed a mixed random-aggregated behaviour. The repulsive (uniform) behaviour was extremely rare.     

Importance sampling with the generalized exponential power density

In this paper, the generalized exponential power (GEP) density is proposed as an importance function in Monte Carlo simulations in the context of estimation of posterior moments of a location parameter. This density is divided in five classes according to its tail behaviour which may be exponential, polynomial or logarithmic. The notion of p-credence is also defined to characterize and to order the tails of a large class of symmetric densities by comparing their tails to those of the GEP density.The choice of the GEP density as an importance function allows us to obtain reliable and effective results when p-credences of the prior and the likelihood are defined, even if there are conflicting sources of information. Characterization of the posterior tails using p-credence can be done. Hence, it is possible to choose parameters of the GEP density in order to have an importance function with slightly heavier tails than the posterior. Simulation of observations from the GEP density is also addressed.
