Paternal relatedness and age proximity regulate social relationships among adult female rhesus macaques.

Kin selection promotes the evolution of social behavior that increases the survival and reproductive success of close relatives. Among primates, maternal kinship frequently coincides with a higher frequency of grooming and agonistic aiding, but the extent to which paternal kinship influences adult female social relationships has not yet been investigated. Here, we examine the effect of both maternal and paternal kinship, as well as age proximity, on affiliative interactions among semifree-ranging adult female rhesus macaques, Macaca mulatta. Kinship was assessed by using both microsatellites and DNA-fingerprinting. Our study confirms that the closest affiliative relationships characterize maternal half-sisters. We provide evidence that adult females are significantly more affiliative with paternal half-sisters than with nonkin. Furthermore, paternal kin discrimination was more pronounced among peers than among nonpeers, indicating that age proximity has an additional regulatory effect on affiliative interactions. We propose that kin discrimination among cercopithecine primates emerges from ontogenetic processes that involve phenotype matching based on shared behavioral traits, such as inherited personality profiles, rather than physiological or physical characteristics.

Coping socialization in middle childhood: tests of maternal and paternal influences.

A theoretical model of parental socialization of children's coping behavior is described and tested with 310 elementary school children (M age = 10.5 years). Mothers and fathers reported on the coping suggestions they made to their children, their own coping strategies, and their perceptions of the family environment. Children reported on their relationships with their parents and on their usual coping behavior. Children's coping efforts were associated with family environment, the quality of the parent-child relationship, parent's own coping, and parent coping suggestions, though these relationships differed by gender and were quite specific. Maternal data were more strongly associated with children's coping than paternal data, and active and support coping were predicted more successfully than avoidance strategies. Analyses supported a model of direct, rather than mediated, effects on children's coping. There was modest support for the interactive effects of maternal coaching and modeling on girls' active coping and boys' avoidant coping.

Developmental trajectories of disruptive behavior problems among sons of alcoholics: effects of parent psychopathology, family conflict, and child undercontrol.

This study examined trajectories of disruptive behavior problems from preschool to early adolescence in 302 boys from a community-recruited sample of high-risk families. Growth modeling showed that paternal alcoholism was associated with elevated levels of sons' disruptive behavior problems. Family conflict predicted more disruptive behaviors at school entry and a slower rate of decline in such problems. Parent antisocial personality disorder (ASPD) exacerbated the effects of high preschool levels of sons' undercontrol on level of disruptive behaviors at school entry; this effect became progressively stronger across time. Low levels of undercontrol protected sons of ASPD parents from experiencing heightened levels of disruptive behaviors both at school entry and increasingly as sons grew older. Implications for subsequent maladjustment are discussed.

Family environment and adolescent psychological well-being, school adjustment, and problem behavior: a pioneer study in a Chinese context.

Chinese secondary school students (N = 365) responded to instruments measuring their family environment, psychological well-being, school adjustment, and problem behavior. Measures of the family environment include perceived paternal and maternal parenting styles, family functioning, and conflict with father and mother. Results from bivariate and canonical correlation analyses showed that in general, adolescents' perceptions of parenting styles, family functioning, and parent-adolescent conflict were significantly related to scores on measures of psychological well-being (general psychiatric morbidity, life satisfaction, purpose in life, hopelessness, and self-esteem), school adjustment (perceived academic performance and school conduct), and problem behavior (smoking and psychotropic drug abuse). The findings suggest that family factors play an important role in influencing the psychosocial adjustment, particularly the positive mental health, of Chinese adolescents.

Externalizing behaviors and minor unintentional injuries in toddlers: common risk factors?

OBJECTIVE: To investigate predictors for externalizing behaviors and minor unintentional injuries in toddlers and to examine whether common risk factors can be identified. METHODS: Linear regression models were used to investigate the contributions of predictors belonging to the domains of child characteristics and parental characteristics. Participants were 117 boys (M = 16.9 months) and their parents. RESULTS: Two common risk factors for externalizing behaviors and minor injuries were identified: maternal low conscientiousness and paternal low self-control. In addition, children's inhibitory control and dispositional frustration as well as maternal externalizing symptoms contributed independently to children's externalizing behaviors. CONCLUSIONS: Results supply some evidence for the interrelatedness of negative outcomes and on the existence of common risk factors. Interventions could aim to address these common risk factors in order to pursue a number of goals at the same time, instead of focusing on only one type of negative outcome.

Theory and methods for research on ethical issues in dementia care.

Swedish research on ethical issues in dementia care is almost exclusively done by nursing scientists. Many of these studies are rightfully acclaimed as exemplary research. But the strong focusing on the nurse and her relation to the patient tends to bias the ethical issues--the attitudes of other persons involved or affected are also in need of investigation. Further, there is a predilection for content analysis at the expense of causal analysis. In this paper an eclectic approach to the study of ethical issues in dementia care is advocated. More interdisciplinary communication and co-operation is also needed--especially between nursing scientists and moral philosophers. To facilitate such communication and co-operation a model for analysis of ethical issues is presented and discussed. To illustrate my ideas I use three articles by researchers from the department of advanced nursing in Umeå: Ekman & Norberg (1988), Norberg & Asplund (1990) and Akerlund & Norberg (1989-90).

Behavioral development of captive male hybrid cercopithecine monkeys.

In this study, we compare the behavioral development of captive male vervet monkeys (Chlorocebus pygerythrus) and Sykes' monkeys (Cercopithecus albogularis) to male hybrids of these species. Focal animal sampling sessions were conducted on the study subjects from birth to 90 months of age. Behavioral categories (affiliative, approach, play, sexual, tension, aggressive) were plotted for each species and the hybrids; curves were fitted using polynomial regression and were evaluated with the Wilcoxon signed ranks test. With the exception of play behaviors, the male C. pygerythrus x C. albogularis hybrids modeled the Sykes' pattern of behavioral development. We suggest that this result reflects a sex-linked paternal effect.

The effect of parental alcohol dependence on perceived children's behavior.

The effect of past-year parental alcohol dependence on perceived children's behavioral problems was assessed using data from a general population sample of 3,409 father-child pairs and 5,892 mother-child pairs. Eight percent of the children living in households containing fathers had an alcoholic father; 2% of those living with mothers had an alcoholic mother. Behavioral problems in the 3 months preceding the interview were assessed using a list of 32 indicators and were evaluated by an adult household member, usually the child's mother. The unadjusted odds of a child's being in the top 10th percentile of the behavioral problem distribution were increased by a factor of 1.7 for paternal alcoholism and 2.2 for maternal alcoholism. After adjustment for social and demographic characteristics of the child and family, the odds ratio for alcohol dependence in the mother dropped to 1.6; the odds ratio for paternal alcohol dependence remained at 1.7. Parental alcohol dependence did not interact with social and demographic factors in its association with children's behavioral problems.

Genetic and environmental contributions underlying stability in childhood obsessive-compulsive behavior.

BACKGROUND: Little is known about the stability of obsessive-compulsive (OC) behavior during childhood. The objective of this study is to determine the developmental stability of pediatric OC behavior and the genetic and environmental influences on stability in a large population-based twin sample. METHODS: Maternal and paternal ratings on the 8-item Obsessive Compulsive Scale of the Child Behavior Checklist (CBCL-OCS) on Dutch mono- and dizygotic twin pairs from 8083 families were collected at ages 7, 10, and 12 years. Using a longitudinal twin design, stability of OC behavior and genetic and environmental influences on stability were determined. Using cutoff criteria, persistent, resilient, and new onset cases were identified in this sample. RESULTS: OC behavior assessed by the CBCL-OCS showed a moderate stability with phenotypic correlations of around .50 for boys and for girls. Stability of OC behavior was influenced by genetic factors, by environmental factors shared by children growing up in the same family, and by non-shared environmental factors. Stability for OCS was lower when categorical data were analyzed than when quantitative definitions were used. CONCLUSIONS: OC behavior is moderately stable in childhood. Stability of OC behavior is influenced by genetic, shared, and non-shared environmental factors.

Characteristics of children of alcoholics: putative risk factors, substance use and abuse, and psychopathology.

A sample of 253 children of alcoholics (COAs) and 237 children of nonalcoholics (non-COAs) were compared on alcohol and drug use, psychopathology, cognitive ability, and personality. COAs reported more alcohol and drug problems, stronger alcohol expectancies, higher levels of behavioral undercontrol and neuroticism, and more psychiatric distress in relation to non-COAs. They also evidenced lower academic achievement and less verbal ability than non-COAs. COAs were given Diagnostic Interview Schedule alcohol diagnoses more frequently than non-COAs. The relation between paternal alcoholism and offspring alcohol involvement was mediated by behavioral undercontrol and alcohol expectancies. Although gender differences were found, there were few Gender X Family History interactions; the effects of family history of alcoholism were similar for men and women. When gender effects were found, they showed greater family history effects for women.

Differential segregation patterns of sperm mitochondria in embryos of the blue mussel (Mytilus edulis).

In Mytilus, females carry predominantly maternal mitochondrial DNA (mtDNA) but males carry maternal mtDNA in their somatic tissues and paternal mtDNA in their gonads. This phenomenon, known as doubly uniparental inheritance (DUI) of mtDNA, presents a major departure from the uniparental transmission of organelle genomes. Eggs of Mytilus edulis from females that produce exclusively daughters and from females that produce mostly sons were fertilized with sperm stained with MitoTracker Green FM, allowing observation of sperm mitochondria in the embryo by epifluorescent and confocal microscopy. In embryos from females that produce only daughters, sperm mitochondria are randomly dispersed among blastomeres. In embryos from females that produce mostly sons, sperm mitochondria tend to aggregate and end up in one blastomere in the two- and four-cell stages. We postulate that the aggregate eventually ends up in the first germ cells, thus accounting for the presence of paternal mtDNA in the male gonad. This is the first evidence for different behaviors of sperm mitochondria in developing embryos that may explain the tight linkage between gender and inheritance of paternal mitochondrial DNA in species with DUI.

Mapping of QTL for Body Conformation and Behavior in Cattle.

Genome scans for quantitative trait loci (QTL) in farm animals have concentrated on primary production and health traits, and information on QTL for other important traits is rare. We performed a whole genome scan in a granddaughter design to detect QTL affecting body conformation and behavior in dairy cattle. The analysis included 16 paternal half-sib families of the Holstein breed with 872 sons and 264 genetic markers. The markers were distributed across all 29 autosomes and the pseudoautosomal region of the sex chromosomes with average intervals of 13.9 cM and covering an estimated 3155.5 cM. All families were analyzed jointly for 22 traits using multimarker regression and significance thresholds determined empirically by permutation. QTL that exceeded the experiment-wise significance threshold (5% level) were detected on chromosome 6 for foot angle, teat placement, and udder depth, and on chromosome 29 for temperament. QTL approaching experiment-wise significance (10% level) were located on chromosome 6 for general quality of feet and legs and general quality of udder, on chromosome 13 for teat length, on chromosome 23 for general quality of feet and legs, and on chromosome 29 for milking speed. An additional 51 QTL significant at the 5% chromosome-wise level were distributed over 21 chromosomes. This study provides the first evidence for QTL involved in behavior of dairy cattle and identifies QTL for udder conformation on chromosome 6 that could form the basis of recently reported QTL for clinical mastitis.

Overt and relational aggression in Russian nursery-school-age children: parenting style and marital linkages.

Maternal and paternal parenting styles and marital interactions linked to childhood aggressive behavior as described in Western psychological literature were measured in an ethnic Russian sample of 207 families of nursery-school-age children. Results corroborated and extended findings from Western samples. Maternal and paternal coercion, lack of responsiveness, and psychological control (for mothers only) were significantly correlated with children's overt aggression with peers. Less responsiveness (for mothers and fathers) and maternal coercion positively correlated with relational aggression. Some of these associations differed for boys versus girls. Marital conflict was also linked to more overt and relational aggression for boys. When entered into the same statistical model, more marital conflict (for boys only), more maternal coercion, and less paternal responsiveness were found to be the most important contributors to overt and relational aggression in younger Russian children.

Long-term fitness consequences of female extra-pair matings in a socially monogamous passerine.

Whether female birds choose extra-pair mating partners to obtain genetic fitness benefits is intensely debated. The most straightforward and crucial test of 'good genes' models of female extra-pair mating is the comparison of naturally 'cross-fostered' maternal half-siblings sharing the same rearing environment as any systematic differences in performance between the two categories of offspring phenotype can be attributed to differential paternal genetic contribution. We analysed local recruitment and first-year reproductive performance of maternal half-siblings in the coal tit (Parus ater), a passerine bird with high levels of extra-pair paternity. We provide a highly comprehensive measure of the long-term fitness consequences of female extra-pair matings based on a large sample of 736 within-pair offspring (WPO) and 368 extra-pair offspring (EPO) from 91 first and 55 second broods, from which 132 breeders recruited into the study population. In contrast to predictions derived from 'good genes' models, we found no differences in local recruitment and seven parameters of first-year reproductive performance when comparing WPO and EPO. These results question the universal validity of findings in other bird species supporting 'good genes' models, particularly as they are based on the best approximation to female fitness obtained so far.

Fathers and daughters: their relationship and personality characteristics associated with the daughter's smoking behavior.

This study examined the interrelationships of domains (i.e., sets) of paternal personality and father-daughter relationship variables and daughter characteristics and their impact on the daughter's smoking. In addition, the interactive effects of individual father and daughter variables on the daughter's smoking were studied. Female college student volunteers (N = 403) and their fathers were given closed-ended questionnaires that included a number of scales assessing father and daughter characteristics. Results indicated that the domains of father and daughter variables each had a direct impact on the daughter's smoking (an independent model). Interactive findings revealed that daughter protective factors (those conducive to her not smoking) could offset the negative impact of paternal risk factors (those conducive to her smoking), and that, to a lesser extent, daughter protective factors further enhanced the positive effect of father protective variables.

[The individualization of care practices for twins during the first year].

BACKGROUND: Mothers of twins have some difficulties to individualize their child-raising activities during the first year. This study was aimed to determine factors influencing such activities. POPULATION AND METHODS: Thirty-seven pairs of twins born after 36 weeks of gestation and weighing more than 2,000 g were included in the study. Relationships between the parents and their children were studied from questionnaires concerning activities during the first trimester and the end of the first year of age. Each item concerning organization of meals and sleeping was graded 1 to 3 according to the degree of individualization of the care. Items concerning support of the mother by the father or other people were graded 1 to 3 according to the degree of this assistance. The physical and psychological status of the mother was also graded according to the presence or not of asthenia and/or depression. Home activities of the mother were also observed. RESULTS: The state of the mother during the first few months had an impact on her mothering behavior: tired or depressed mothers tend to treat the twins collectively and simultaneously. No link was found between social, paternal or general familial support and the degree of individualization in the maternal behaviors. CONCLUSIONS: Several factors can interfere with the psychological repercussions of a twin birth on the mother and subsequent psychoemotional development of children. Further studies are necessary to understand how each parent contributes to the organization of the family system.

Filial cannibalism improves survival and development of beaugregory damselfish embryos.

Cannibalism of small numbers of offspring by a parent has been proposed as an adaptive parental strategy, by providing energy to support parental care. However, there are few empirical studies to support this hypothesis. We conducted field and laboratory experiments to investigate partial filial cannibalism in Stegastes leucostictus, a coral reef fish with paternal care. Partial cannibalism was shown to be common, and males were found to remove developing embryos from throughout a clutch in a random pattern, rather than in the more aggregated pattern seen during embryo predation. Males that received a diet supplement grew faster than control males, but did not engage in less cannibalism. Also, males did not concentrate cannibalism on early embryonic stages with the highest energetic value. Experimental reduction of embryo densities was found to significantly increase embryo development rate and survival from egg deposition to hatching, and experimental reduction of oxygen levels significantly increased rates of partial filial cannibalism by males. Artificial spawning sites with low oxygen levels were avoided by spawning females, and cannibalism rates by males were higher. We propose that partial filial cannibalism serves as an adaptive parental strategy to low oxygen levels in S. leucostictus by increasing the hatching success of embryos.
