The evolutionary age of the Muscoidea has also never been directly assessed by phylogenetic means. In a subsequent, more intensive analysis, Wiegmann et al. The age of splits within the Muscoidea has yet to be examined. Mitochondrial mt genomes have been established as a powerful tool for reconstructing phylogenetic relationships because of their ability to provide more phylogenetic information than individual genes [ 9 — 16 ].
Intergenerational Links in Victimization: Prosocial Friends as a Buffer
The use of whole mt genome sequences in insect phylogenetics has produced some remarkable results, e. Since Clary and Wolstenholme published the first insect mitochondrial genome sequence in [ 20 ], Diptera has been a primary model system for mt genome research both for phylogenetic and molecular evolution studies.
The number of mt genome sequences from Diptera deposited in GenBank has grown rapidly. As of Maycomplete or nearly complete dipteran mt genomes had been published on GenBank, representing 29 families.
However, much of the dipteran mt genome data is derived from species of the model organism Drosophila [ 21 ], whereas most families have not been sequenced and those families for which mt genomes are available are represented by only one or two species. This is particularly true for the muscoid families. Prior to this study, there were only four complete mt genome sequences available for Muscoidea, representing two of the four families: Muscidae from which three species have been sequenced and Scathophagidae one species sequenced.
Herein, we presented two nearly complete mt genomes representing the remaining two muscoid families: Fanniidae and Delia platura Meigen, Anthomyiidae. We used procedures and quality control methods proposed by Cameron [ 22 ] to re-annotate all mt genomes from muscoid flies and examine genome variability across the group. A phylogenetic analysis of cyclorrhaphan mt genomes finds further evidence that Muscoidea is paraphyletic, which a molecular dating analysis suggests that divergence of the muscoid grade occurred in the Eocene.
Material and Methods Ethics statement No specific permits were required for the insects collected for this study. The specimens were collected using sweep nets. The field studies did not involve endangered or protected species. Initial fragments were amplified using universal primers [ 15 ].
Several species-specific primers were designed based on results from initial sequencing with amplification primers and used for internal PCRs S1 Table. The amplification conditions were: The quality of PCR products were evaluated by agarose gel electrophoresis.
Sequence analysis was performed as follows. The publisher's final edited version of this article is available at J Child Adolesc Trauma Abstract This study investigated whether having friends who engaged in more prosocial than antisocial behaviors buffered the associations between family-of-origin aggression and later victimization. Moreover, having friends who engaged in more prosocial than antisocial behaviors had both a direct inverse relationship with dating partner victimization.
This also buffered the risk for dating victimization associated with father-daughter aggression. Though exposure to family aggression frequently emerges as a risk factor for later victimization by dating partners Stith et al.
Moreover, even in studies with significant associations, a notable number of participants are resilient to the link between family-of-origin aggression and later victimization from dating partners and friends. This study aims to better understand the links between family aggression and dating and friend victimization by first considering whether type of family violence exposure is a distinguishing factor.

Second, because adolescence is a time of increasing interest and autonomy in developing affiliations with peers, it is important to assess who is selected as friends: Is the continuity of victimization affected by whether those who are selected as friends engage primarily in prosocial or deviant behavior? The present study extends what is known about the role of friends in trajectories of risk by testing whether affiliating with friends who engage in more prosocial than antisocial behaviors may protect against the risk of victimization by dating partners and friends in adolescence.
Family Aggression and Victimization Studies have consistently found that individuals with a history of childhood physical or sexual abuse are 2 to 4 times more likely to experience later physical, sexual, or psychological victimization from dating partners compared to those without such histories Cloitre et al.
Within families, it is unclear whether aggression perpetrated by mothers and fathers may have differential risks for females and males in the risk for later victimization.

Other studies suggest that mothers, compared to fathers, have a more potent role in later victimization from peers Baldry, ; Hendy et al. Prior work has identified prospective associations between exposure to family aggression and affiliation with deviant peers Ehrensaft et al. They may also espouse violent attitudes regarding dating relationships Ehrensaft et al. Lansford, Criss, Pettit, Dodge, and Bates also found that antisocial friends strengthened the association between harsh parenting and negative outcomes, suggesting that antisocial peers may amplify risks associated with exposure to family aggression.
In contrast, very few studies, to our knowledge, have examined the role of prosocial friends—or those who engage in community service, get good grades, and are liked by teachers— in buffering against the risk of victimization. Garrido and Taussig found that within a small sample of adolescents who were removed from their homes due to maltreatment, prosocial peers moderated the association between parent-to-parent aggression and later dating aggression, but not victimization. Further work is needed in this area, especially given that social development models highlight the role of prosocial friends in promoting resilient outcomes Herrenkohl et al.
Though prior studies typically have assessed either antisocial friends or prosocial friends, it is very likely that adolescents are not quite that unidimensional in their friendships. Rather than categorizing friends as one or the other, it may be more accurate to conceptualize friends as engaging in both antisocial and prosocial behaviors—but in different proportions. That is, friends who engage in a higher proportion of prosocial than antisocial behaviors may be protective, whereas friends who engage equally in both prosocial and antisocial behaviors or engage in fewer prosocial than antisocial behaviors may be more risky.
In terms of buffering the risk of victimization from parents to peers, affiliating with friends who engage in a higher proportion of prosocial than antisocial behaviors may serve to challenge expectations for aggressive behavior within relationships.
Gender Differences in Victimization Findings on gender differences in rates of victimization have been mixed, with some studies finding higher rates among females, and still others reporting higher rates among males e.
A meta-analysis found that females in particular might be at increased risk for dating victimization following exposure to family aggression Stith et al. The present study further explores the role of gender as a moderator in the interactions between family and friend influences on victimization. Victimization in Late Adolescence Despite the accumulating evidence that victimization occurs widely and leads to a host of negative outcomes among adolescents, most prior work has focused on adolescents prior to the age of 17 e.
Few studies have assessed victimization among a community sample of individuals between the ages of 17 to 21, referred to as late adolescents American Academy of Pediatrics, Present Study The first goal of the present study is to investigate direct associations between different types of family aggression in early adolescence and victimization from dating partners and friends in late adolescence. Total family aggression along with four separate types of family aggression will be tested: We hypothesize that family aggression will be associated with victimization by dating partners and friends in late adolescence Hypothesis 1 and do not have differential predictions based on type of family aggression.
The second aim involving the protective influences of prosocial-to-antisocial friend behavior tests two hypotheses: Methods Overview Participants for the present study include adolescents and their parents who were recruited as part of a two-cohort longitudinal, multi-wave research study examining the effects of family conflict on parent and child outcomes. Inclusion criteria were that a families included two parents and at least one child; b families lived together for at least the last 3 years; and c all participants were able to read and speak English.
Children in the first cohort were recruited at age 9—10 when they began the study and the children in the second cohort, designed to match the first cohort, were in middle school when they began the study approximately three years later. The present study includes data from two time points that were spaced approximately 5 years apart.
At the first time point, adolescents and their parents reported on family aggression experienced within the home. All data were collected in computer-administered questionnaires as part of a larger laboratory procedure.
Families were compensated for their time and effort in each time point.
