Normal responses to sexually anatomically detailed dolls

The behaviors and verbalizations of normal, preschool age boys and girls during interactions with sexually anatomically detailed (SAD) dolls were examined. A structured, nonsuggestive interview with each child was videotaped, and five behaviors and five verbalizations were coded for each of five phases of the interview. A two-way ANOVA (gender × phase) showed that during those phases when the dolls were undressed, both boys and girls showed more sexual exploratory play, aggressive behavior which was nonsexual, and active avoidance. Across all phases, nonsexual aggression accounted for 31% of the boys' and 22% of the girls' total responses. Behavioral and verbal sexual exploratory play represented 42% of the boys' responses and 50% of the girls' responses. In contrast, sexually aggressive behavior accounted for only 1% and 2% of the boys' and girls' responses, respectively. Girls interacted with the dolls more than did boys. Additionally, girls demonstrated more affection to the dolls than did the boys, and boys displayed more anxiety with the dolls than did girls. Investigators should be cautious as to inferences about preschoolers' interactions with SAD dolls, especially interactions of a sexual or aggressive nature which do not clearly depict fondling or intercourse.     

Risk factors and consequences of unwanted sex among university students: hooking up, alcohol, and stress response

This is the first study of unwanted sexual experiences in the collegiate "hooking-up" culture. In a representative sample of 178 students at a small liberal arts university. Twenty-three percent of women and 7% of men surveyed reported one or more experiences of unwanted sexual intercourse. Seventy-eight percent of unwanted vaginal, anal, and oral incidents took place while--"hooking up,"--whereas 78% of unwanted fondling incidents occurred at parties or bars. The most frequently endorsed reason for unwanted sexual intercourse was impaired judgment due to alcohol. The most frequently endorsed reason for unwanted fondling was that it happened before the perpetrator could be stopped. Of those affected by unwanted sexual intercourse or unwanted fondling, 46.7% and 19.2% reported unwanted memories, 50% and 32.7% reported avoidance and numbing responses, and 30% and 26.9% reported hyperarousal responses, respectively. A preliminary model of unwanted sex and collegiate social dynamics is proposed to provide a heuristic for further research.     

Same Routines,Different Effects: Gender,Leisure, and Young Offending

The current study seeks to extend routine activity theory by examining how gender conditions the relationship between leisure activities and adolescent delinquency. Using OLS regression with a sample of high school students from Toronto (n = 2,209), we find that (1) engaging in more unstructured and unsupervised activities with peers is associated with delinquency more strongly for boys than for girls, but is associated with substance use equally across gender; (2) this pattern is likely due to gender differences in the locations or contexts of leisure activities; and (3) prosocial leisure activities are associated with less delinquency only for boys. In general, routine activity theory appears apt at explaining the substance use of boys and girls, but is less capable of explaining the property and violent offending of girls. We discuss our findings and their implications for the growing body of research extending routine activity theory to explain gender differences in delinquency.     

Gender Role and Gender as Predictors of Behavior Problems in Children Exposed to Intimate Partner Violence

Children exposed to intimate partner violence (IPV) are likely to develop behavior problems, but findings are mixed regarding whether girls and boys are differentially affected. Bem (Journal of Personality and Social Psychology, 31, 634–643, 1975) argued that gender role is an important predictor of mental health, and this relationship may differ for males and females due to societal gender norms. Given the gendered nature of IPV, we examined whether gender role interacted with gender to predict behavior problems in IPV-exposed children (n = 176). Among four-year-old children, gender-typed gender roles were a risk factor for girls but not boys, and androgynous gender roles were protective for both boys and girls on average. However, post hoc analyses indicated the amount of IPV exposure mattered; androgynous girls exposed to chronic IPV had more behavior problems. Results illustrate the importance of societal and family gender norms in determining children’s risk for behavior problems following exposure to IPV.     

Medical examination of sexually abused children: medico-legal value

The Department of Forensic Medicine (forensic pathology and clinical forensic medicine), Aarhus, Jutland, Denmark, performs examinations of children suspected to have been sexually abused when reported to and requested by the police in Jutland, Denmark. Jutland covers an area of 210,000 km2 with about 300,000 inhabitants in Aarhus. A colposcope initially equipped with an Olympus camera, but now with a video camera attached has been used since 1994. Since 1994 the department has performed more than 100 examinations of children suspected of having been sexually abused. A preliminary study was taken to evaluate all cases from 1995 including the legal outcome. RESULTS: The material included 34 cases with three boys, mean age 11 years, and 31 girls, mean age 8 years, at the time of the examination. The sexual abuse events were fondling including penetration of the vagina, vaginal (14), anal (7), and oral (5) intercourse as well as cunnilingus and nontouching abuses. The medical examination was most often performed more than a week after the abuse. The examination revealed normal findings in 23 cases, nonspecific findings including erytherma in 13 cases, and in only one child was a traumatic lesion with rupture of the hymen seen. The perpetrators were above 25 years of ane and were family members or someone known to the child. Nine perpetrators were convicted at court, of whom three admitted having abused the child. CONCLUSION: A medical examination in cases of sexual child abuse seldom provides a legal proof of sexual abuse. The most important is the story told by the child. Therefore, the examination is a supplement which may support or remain neutral to the story told by the child.     

Sex as a moderator and perceived peer pressure as a mediator of the externalizing-delinquency relationship: A test of gendered pathways theory

Purpose

The current study sought to determine whether sex moderated peer mediation of the externalizing-delinquency relationship as part of a larger test of the gendered pathways theory of crime.

Methods

Data gathered from 4,144 (2,079 males and 2,065 females) members of the National Longitudinal Survey of Youth-Child sample were subjected to simple correlational and moderated mediation analysis.

Results

Externalizing behavior and delinquency correlated equally in boys and girls but in testing a full moderated mediation model it was discovered that sex moderated the mediating effect of perceived peer pressure on the externalizing–delinquency relationship. Whereas externalizing behavior predicted delinquency in both boys and girls, perceived peer pressure only mediated the externalizing-delinquency relationship in boys.

Conclusions

These results support the gendered pathways to delinquency model to the extent that the relationship between childhood externalizing behavior and delinquency was mediated by perceived peer pressure in males but not females. The implications of these results for theoretical refinement of the gendered pathways approach and crime prevention and intervention are discussed.     

Adolescent girls investigated for sexual abuse: history,physical findings and legal outcome

Objective: The aim of the study was to summarize the history of assault and record the results of medicolegal examination in adolescent girls under investigation for alleged sexual abuse, and to monitor the outcome of the legal process. The investigation period was 1990–94. Method: A consecutive series of 94 0-para girls, aged 9–22, median age 15.0 years, were examined in the head-to-toe manner including anogenital examination. Girls were referred from investigating police and social authorities. Only non-acute examinations were performed. Findings considered consistent with abusive vaginal penetration were hymenal distortion including deep clefts, hymenal and vestibular scarring, and introital diameter permitting vaginal inspection with a 17 mm speculum in the absence of consensual intercourse. Perianal scarring was recorded. STD sampling was made on indication. Findings were documented on body sketches. Medicolegal conclusions were grouped into three categories according to history and physical findings. Information on the outcome of legal procedures was collected from referring authorities. Results: For 82% (77/94) of the girls, referring agencies provided examining physicians with a detailed and consistent history of abuse, presented results comprise these 77 girls. Intrafamiliar abuse was alleged by 81% (62/77), onset prior to menarche by 53% (41/77), and repeated abuse by 74% (57/77) of the girls. Abusive genital penetration was reported by 77% (59/77) and anal penetration by 19% (14/77). Sequelae after admitted self-inflicted injury were found in 15% (12/77). Deep hymenal celfts and/or vestibular scars were found in 59% (35/59) of the girls reporting penetrative abuse, compared with 6% (1/16) when non-penetrative abuse was alleged, P<0.001. Girls with experience of voluntary intercourse could all be examined with a 25 mm speculum. Of the 17 girls without experience of consensual intercourse but alleging abusive penetration, 47% (17/36) could easily be examined with a 17 mm speculum, compared to none of 13 reporting non-penetrative abuse, P<0.001. Non-specific anal abnormalities occurred in 10 (13%) girls; more often when anal abuse was reported, P<0.001. No specific STDs were found. The medicolegal conclusion supported a history of abusive genital penetration in 41 (69%) cases; findings were non-specific in 11 cases and a normal anogenital status was found in 25 cases. The alleged abuse of 34 of the 77 (44%) girls was tried in court. One suspect was acquitted, 32 men were convicted of the abuse of 33 girls. Eleven perpetrators admitted abuse, and their histories were in concordance with the abuse alleged by the victims, as well as with the physical findings. Conclusion: A medicolegal diagnosis of alleged non-acute cases of sexual abuse relies on a detailed history. Adolescent girls alleging abuse may exhibit signs of admittedly self-inflicted extragenital injury. Our findings confirm that non-penetrative sexual acts leave no lasting genital signs, but that repeated abusive genital penetration significantly more often than non-penetrative abuse leaves deep posterior hymenal clefts and/or vestibular scarring, and a hymenal opening allowing examination with 17–25 mm specula also in girls without experience of voluntary intercourse. In cases with a confessing perpetrator, no discordance was found between the history of the victim, medicolegal conclusion and the history of the perpetrator.     

Approaches to chronological age assessment based on dental calcification

The aim of the present study was to find an accurate estimation of chronological age using a small number of selected teeth. For this purpose, the method devised by Nolla [C. Nolla, The development of the permanent teeth, J. Dent. Child. 27 (1960) 254-266.] was used: the development of each of the teeth was determined according to this method on 374 radiographs, 195 of boys (mean age 8.59) and 179 of girls (mean age 8.75). The 28 variables representing the calcification stages were analyzed using cluster analysis followed by multivariate analysis (multiple linear regression model). Patient age was considered to be a dependent variable. Our study showed that antimere teeth are the most homogeneous as regards stages of development. The prediction was more accurate for boys and girls below 10 years of age, using teeth 21, 43 and 46 from boys and teeth 21, 46 and 47 from girls. These teeth accounted for 80% total variance of chronological age for dental calcification. Standard error was +/-1.4 years for boys and +/-1.2 years for girls. When the age of the children remained completely unknown, the best estimates were provided by teeth 43, 47, 46 and 44 from boys and teeth 44, 47 and 43 from girls.     

The accuracy of three methods of age estimation using radiographic measurements of developing teeth

The accuracy of age estimation using three quantitative methods of developing permanent teeth was investigated. These were M?rnstad et al. [Scand. J. Dent. Res. 102 (1994) 137], Liversidge and Molleson [J. For. Sci. 44 (1999) 917] and Carels et al. [J. Biol. Bucc. 19 (1991) 297]. The sample consisted of 145 white Caucasian children (75 girls, 70 boys) aged between 8 and 13 years. Tooth length and apex width of mandibular canine, premolars and first and second molars were measured from orthopantomographs using a digitiser. These data were substituted into equations from the three methods and estimated age was calculated and compared to chronological age. Age was under-estimated in boys and girls using all the three methods; the mean difference between chronological and estimated ages for method I was -0.83 (standard deviation +/-0.96) years for boys and -0.67 (+/-0.76) years for girls; method II -0.79 (+/-0.93) and -0.63 (+/-0.92); method III -1.03 (+/-1.48) and -1.35 (+/-1.11) for boys and girls, respectively. Further analysis of age cohorts, found the most accurate method to be method I for the age group 8.00-8.99 years where age could be predicted to 0.14+/-0.44 years (boys) and 0.10+/-0.32 years (girls). Accuracy was greater for younger children compared to older children and this decreased with age.     

Comparison of the three age estimation methods: Which is more reliable for Turkish children?

BackgroundThree atlases—the GÖK, the Greulich–Pyle (GP), and the Tanner–Whitehouse (TW3)—are used frequently for age determination in Turkey. The purpose of this study was to evaluate the applicability of these three methods related to the skeletal age assessment for Turkish adolescents.Materials and methodsThe conventional roentgenograms of the left hands and wrists, elbows, shoulders, and pelvises of 333 healthy Caucasian children (164 females, 169 males) who fit the study and the criteria of each atlas were obtained. The mean differences (± standard deviation [S.D.] in years) between the chronologic age (CA) and the skeletal age (BA), which were obtained by using each age estimation method, were calculated and tested using t-test.ResultsFor girls, the most accurate method was the TW3 (mean differences (d): ?0.21 (p < 0.05)), following by the GP (d: 0.66 (p < 0.001), and the GÖK (d: 2.99 (p < 0.001)). For boys, the most accurate method was the GP (d: ?0.02 (p > 0.05)), followed by the TW3 (d: ?0.18 (p < 0.05)) and GÖK (d: 1.05 (p < 0.001)).Discussion and conclusionsResults show that the TW3 (for girls) and the GP (for boys) methods are more appropriate than the GÖK atlas for estimating the BA. GÖK could be used for boys aged 11–14 years but it should not be used for girls.     

Excretion of Delta9-tetrahydrocannabinol in sweat

The aims of this study were: first, to determine the accuracy of the Cameriere method for assessing chronological age in children based on the relationship between age and measurement of open apices in teeth and, second, to compare the accuracy of this method with the widely used Demirjian et al. method and with the method proposed by Willems et al. Orthopantomographs taken from white Italian, Spain and Croatian children (401 girls, 355 boys) aged between 5 and 15 years were analysed following the Cameriere, Demirjian and Willems methods. The difference between chronological and dental age was calculated for each individual and each method (residual). The accuracy of each method was assessed using the mean of the absolute values of the residuals (mean prediction error). Results showed that the Cameriere method slightly underestimated the real age of children. The median of the residuals was 0.081 years (interquartile range, IQR=0.668 years) for girls and 0.036 years for boys (interquartile range, IQR=0.732 years). The Willems method showed an overestimation of the real age of boys, with a median residual error of -0.247 years and an underestimation of the real age of girls (median residual error=0.073 years). Lastly, the Demirjian method overestimated the real age of both boys and girls, with a median residual error of -0.750 years for girls and -0.611 years for boys. The Cameriere method yielded a mean prediction error of 0.407 years for girls and 0.380 years for boys. Although the accuracy of this method was better for boys than for girls, the difference between the two mean prediction errors was not statistically significant (p=0.19). The Demirjian method was found to overestimate age for both boys and girls but the mean prediction error for girls was significantly greater than that for boys (p=0.024), and was significantly less accurate than the Cameriere method (p<0.001). The Willems method was better than that of Demirjian (p=0.0032), but was significantly less accurate than that of Cameriere (p<0.001).     

Age of attainment of mineralization stages of the permanent dentition.

The ages at which the maxillary and mandibular teeth of 121 boys and 111 girls reached 14 mineralization stages were determined from serial cephalograms at the Burlington Growth Centre. The present data are more comprehensive than any previously available and can be applied to chronological age determinations in juveniles of indefinite age, and of specimens in anthropological and forensic investigations. The sexes differed in the age at which they attained the stages of mineralization, with the canines demonstrating the greatest difference. In each sex, the ages at identical stages were similar for the corresponding teeth in the maxilla and mandible. Variability in age was greater among the males, especially for the first premolars, and increased with age, except for the third molars. Variability in age of third molar mineralization was greater in females and diminished among both sexes at late stages of root formation.     

Secular Trend in the Development of Permanent Teeth in a Population of Istria and the Littoral Region of Croatia

The study evaluated secular trends in dental development during a period of 30 years, correlation between dental and chronological age in Istria and the littoral region of Croatia. The sample consisted of 1000 panoramic radiographs of children, aged 6–16 years (mean 10.0 ± 1.8), taken in the period 1977–1979 (N = 500; 243 females) and 2007–2009 (N = 500; 299 females). Dental age was assessed according to Demirjian's method. Correlation between chronological and dental age was linear, positive, high, and statistically significant in both periods and genders, ranging from 0.73 to 0.86. Dental age was underestimated when compared to chronological age by 1 year on average, more 30 years ago (?1.35 ± 1.17) than today (?0.63 ± 1.09), less for girls (?0.80 ± 1.22) than boys (?1.21 ± 1.10). A statistically significant positive secular trend in acceleration of dental development was present of 0.72 years during the 30‐year period and was more significant in girls than boys (0.83‐ and 0.51‐year acceleration).

Accuracy of Three Age Estimation Methods in Children by Measurements of Developing Teeth and Carpals and Epiphyses of the Ulna and Radius

Abstract: The aim of this study was to compare the accuracy of three methods for age estimation in children: the measurements of open apices in tooth roots (T), the ratio between the total area of carpal bones and epiphyses of the ulna and radius (HW), and the combined method (THW). The sample consisted of 288 Caucasian Italian children (152 boys and 136 girls) aged between 5 and 15 years. Accuracy was determined as the difference between estimated age and chronological age, and accuracy was assessed by analyzing individuals’ orthopantomograms and hand‐wrist radiographs. Accuracies were 0.41 years for girls and 0.54 years for boys with the THW method; for the HW method, 1.00 years for girls and 0.92 years for boys; and for the T method, 0.62 years for girls and 0.71 years for boys. THW is the most accurate technique for age estimation in these children.     

Bone age assessment: the applicability of the Greulich-Pyle method in eastern Turkish children

The aim of this study was to investigate whether or not the Greulich-Pyle (GP) method is adequate for Turkish children. A group of 767 individuals (425 girls and 342 boys) between 7 and 17 years were studied. Bone age (BA) from plain radiographs of left hands and wrists by GP standards was estimated. The total mean differences between BA and chronological age (CA) for girls and boys were found to be 0.20 and -0.13 years, respectively. There were significant differences between BA and CA in age groups 7-, 8-, 10-, 11-, 12-, 13-, 15-, and 16-year-olds for girls and 7-, 10-, and 12-year-olds for boys. The results of this study suggest that the mean differences between BA and CA are low enough to be of no practical significance, and thus, for the time being unless any other methods will be proved more useful, this method could be used in all age groups.     

GENDER,FRIENDSHIP NETWORKS,AND DELINQUENCY: A DYNAMIC NETWORK APPROACH

Researchers have examined selection and influence processes in shaping delinquency similarity among friends, but little is known about the role of gender in moderating these relationships. Our objective is to examine differences between adolescent boys and girls regarding delinquency‐based selection and influence processes. Using longitudinal network data from adolescents attending two large schools in AddHealth (N = 1,857) and stochastic actor‐oriented models, we evaluate whether girls are influenced to a greater degree by friends’ violence or delinquency than boys (influence hypothesis) and whether girls are more likely to select friends based on violent or delinquent behavior than boys (selection hypothesis). The results indicate that girls are more likely than boys to be influenced by their friends’ involvement in violence. Although a similar pattern emerges for nonviolent delinquency, the gender differences are not significant. Some evidence shows that boys are influenced toward increasing their violence or delinquency when exposed to more delinquent or violent friends but are immune to reducing their violence or delinquency when associating with less violent or delinquent friends. In terms of selection dynamics, although both boys and girls have a tendency to select friends based on friends’ behavior, girls have a stronger tendency to do so, suggesting that among girls, friends’ involvement in violence or delinquency is an especially decisive factor for determining friendship ties.     

Heterogeneity in the association between social-emotional adjustment profiles and deviant behavior among male and female serious juvenile offenders

This article examines the relation among gender, social-emotional adjustment, and deviant behavior among serious juvenile offenders. A sample of 105 adolescent offenders completed questionnaires assessing social-emotional characteristics and self-reported involvement in deviant behaviors. Results indicate significant associations between distress and restraint in predicting deviance, a finding that was invariant across gender. Analysis of four distinct social-emotional profiles found that membership in the reactive group was associated with the greatest amount of deviant behavior. Results also indicate that not only do serious offending girls internalize more than serious offending boys, they appear equally likely to externalize. However, although boys exhibit less distress than girls, those boys who report high rates of deviance may exhibit internalizing and externalizing problems similar to girls. The use of social-emotional measures in general, and distinct profiles in particular, may aid in targeting specific programming and treatment in an effort to provide offenders with more effective interventions.     

Estimation of age from epiphyseal union at the wrist and ankle joints in the capital city of India

Various studies conducted in and outside India for estimation of age from long bone joints revealed that unlike other vital parameters no uniform pattern exists for epiphyseal union of long bones in different countries of the world and also in different parts of the same country. A radiological study was conducted in 180 boys and girls of the capital city of India, Delhi, between the age group of 14-20 years to find out the age at which epiphyseal union at wrist and ankle joint takes place. The result of the study showed that the wrist joint epiphyseal union is completed in all cases in the age group of 19-20 years in males and 18-19 years in females. In the ankle joint, 17-18 years was the age group in males and 16-17 years the age group in females which showed complete epiphyseal union in all cases.
