Stability of self-control and gender

PurposesThis study provides a rigorous test of gendered nature of self-control stability hypothesis by examining the existence and persistence of gender differences in self-control, and gender differences in developmental patterns of self-control and in source of self-control.MethodsFive-wave longitudinal data of Korean youths from age 10 to 14 are analyzed. t-tests are conducted to examine whether males have significantly lower self-control than females and whether the self-control differences across two genders persist. To test gender differences in developmental patterns of self-control, growth mixture modeling is utilized. Finally, hierarchical linear modeling is used to examine gender differences in the relationships between social factors and self-control.ResultsThe study shows that gender differences in self-control persist over the short term but not over the long term, that males and females experience similar developmental patterns of self-control, and that similarities appear in the relationships between social factors and self-control across both genders.ConclusionsThis study provides partial support for Gottfredson and Hirschi’s arguments on persistent gender differences in self-control and parenting’s main effect on self-control, while strong relative stability is found. The findings indicate that the stability postulate and the relationships between social factors and self-control are applicable to both genders.     

On the relationships between gender, power control, self-control, and crime

This article bridges the gap between two theories that attempt to explain the gender - crime relationship. Power-control theory posits that power relationships of parents in the public sphere are reflected in their relationship at home. Different kinds of households are thus distinguished by degrees of patriarchy. Differential socialization generates gender differences in crime across households. Gottfredson and Hirschi's general theory purports that low self-control explains all crime across all groups, yet little research explored the link between low self-control and crime both among, as well as between, genders. Linking low self-control and power-control theories, this study examined the relationships gender, power-control, self-control, and crime. Results indicated that while low self-control explained both male and female criminality, the effect of parenting on the development of low self-control was complex; males and females differentially responded to parents' control. The gender-based processes that impact the development of self-control should further be explored.     

Graffiti vandalism: Frequency and context differences between the sexes

This paper explores a popular yet highly destructive form of property crime — graffiti vandalism. The localities of such destruction selected for study were male and female restrooms. Three hundred and ninety-two cases were collected and analyzed. Prior research theorized the existence of a significant difference in the amount of graffiti produced between the sexes. (It was believed that males produce more graffiti than females). Analysis, however, revealed equal production of graffiti by males and females.Content differences between the sexes were hypothesized. The content categories included homosexual, heterosexual, nonsexual (humorous and political statements) and racial graffiti. The findings as they relate to content differences between the sexes are presented and discussed relative to sex-role socialization theory.     

The gender gap in death penalty support: An exploratory study

One of the more enduring observations in the study of death penalty support within the United States is the strong divide between males and females. Men have consistently shown significantly higher levels of support for capital punishment than women. This divide between males and females has appeared in nearly every survey, over time, and across a variety of methodological designs. Using data from the cumulative (1972-2002) data file for the National Opinion Research Center (NORC) General Social Surveys, this study attempted to understand the basis for this gender gap. It examined gender differences in socioeconomic status, gender inequality, gender socialization, religion/religiosity, political ideology, positions on right-to-life and other social issues, fear of crime and victimization experience, experience with the criminal justice system, philosophies of punishment, and attribution styles. The findings revealed that the effect of gender on capital punishment support continued to be robust despite controlling for the effects of all of these explanations.     

Informal Controls and the Explanation of Propensity to Offend: A Test in Two Urban Samples

Propensity to offend is an important and stable predictor of offending. A person’s propensity is often thought of as a multidimensional trait consisting of morality and low self-control. The aim of this paper is to explain individual differences in propensity to offend as one single construct and two of its dimensions, namely morality and low self-control. It is well established that low levels of morality and low self-control increase the risk of offending. However, there is less empirical research that focuses on the main predictors of morality and self-control. Therefore the main research question for this study is to explain to what extent parental attachment, parental control and the school social bond have a direct effect on one’s propensity to offend (low morality or delinquency tolerance and low self-control). The data are drawn from two different samples of young adolescents in Antwerp, Belgium (N = 2,486), and Halmstad, Sweden (N = 1,003). The results show that parental control, parental attachment and the school social bond have direct effects on individual differences in propensity to offend, regardless of individual background variables. The results are highly equivalent in both samples. The similarity of the results across two independent samples suggests that the findings are stable. Implications for further studies are discussed.     

Genetic and environmental contributions to stability and change in levels of self-control

Purpose

There has been an emerging body of research estimating the stability in levels of self-control across different sections of the life course. At the same time, some of this research has attempted to examine the factors that account for both stability and change in levels of self-control. Missing from much of this research is a concerted focus on the genetic and environmental architecture of stability and change in self-control.

Methods

The current study was designed to address this issue by analyzing a sample of kinship pairs drawn from the Child and Young Adult Supplement of the National Longitudinal Survey of Youth 1979 (CNLSY).

Results

Analyses of these data revealed that genetic factors accounted for between 74 and 92 percent of the stability in self-control and between 78 and 89 percent of the change in self-control. Shared and nonshared environmental factors explained the rest of the stability and change in levels of self-control.

Conclusions

A combination of genetic and environmental influences is responsible for the stability and change in levels of self-control over time.     

Genetic and Environmental Overlap between Low Self-Control and Delinquency

Low self-control has emerged as a consistent and strong predictor of antisocial and delinquent behaviors. Using the twin subsample of the National Longitudinal Study of Adolescent Health (Add Health), genetic analyses were conducted to examine the genetic and environmental contributions to low self-control and offending as well as to their relationship with one another. The results revealed that low self-control and criminal behaviors are influenced by genetic and nonshared environmental factors with the effects of shared environmental factors being negligible. In addition, the co-variation between low self-control and criminal behaviors appears to be largely due to common genetic and nonshared environmental factors operating on both phenotypes. The implications of these findings on the current understanding of Gottfredson and Hirschi??s general theory of crime are discussed.     

The Relationship between Self-Control in Adolescence and Social Consequences in Adulthood: Assessing the Influence of Genetic Confounds

Purpose

Assess the relationship between levels of self-control in adolescence and a variety of later-life outcomes and evaluate the confounding effects of genetic factors.

Methods

The current study employed data from the National Longitudinal Study of Adolescent Health (Add Health) and examined whether levels of self-control in adolescence are related to economic, educational, employment, health, relationship and family, and behavioral outcomes in adulthood using DeFries-Fulker regression-based analyses.

Results

Analyses employing non-genetically sensitive methods indicated robust associations between self-control and various social consequences. After estimating genetically-sensitive analyses, however, many associations were no longer significant. Those associations which remained significant were in the reversed direction relative to the non-genetically sensitive models. Additionally, further analyses indicated that some of the remaining significant associations were influenced by nonshared genetic effects.

Conclusions

The findings indicate that even after controlling for the effect of genetic factors, levels of self-control are associated with differences in a variety of social outcomes. However, given the reduction in the number of significant associations and reversal of associations in the genetically sensitive models, analyses of the social consequences of low self-control which do not account for the effect of genetic factors are likely misspecified.     

Tooth eruption times of permanent teeth in male and female adolescents in Niedersachsen

The aim of this study was to determine the eruption times of permanent teeth, excluding third molars, in a defined area population of a country district in Lower Saxony. The authors investigated 2495 oral findings of 664 patients (male 315, female 349) in a longitudinal study. The minimum age was 3.00 years and the maximum age 24.00 years. The dental findings were collected over a period of about 20 years (1980-2002). The oral findings per child/adolescent were assessed between one and 16 times. The eruption times of teeth in females are earlier than those for the same teeth in males. Further, the permanent dentition in females is completed earlier than in males. The tooth eruption occurs symmetrically in both jaws. The comparison of both jaws revealed a slightly advanced eruption of the lower jaw teeth for both sexes. There is a noteworthy change in the eruption sequence of the teeth. In contrast to other reports we determined that the eruption of the canine proceeds the eruption of the second premolar. We found no acceleration of the dentition when compared to other reports and confirmed the rules of tooth eruption in man. Oral examination of teeth is a simple tool to calculate tooth eruption intervals. This first investigation on a population of Lower Saxony revealed a change in the eruption sequence of permanent teeth. The findings are relevant for dental treatment planning and should be reconfirmed at certain intervals.     

Sex Differences in Physical and Indirect Aggression: A Developmental Perspective

Males generally use aggression more often than females. However, the magnitude of difference between the sexes varies widely according to the type of aggression that is considered, and according to the developmental period studied. Taking a developmental perspective, this paper reviews research that compares the progression of physical aggression (predominantly used by males) with indirect aggression (predominantly used by females) among males and females. Existing empirical evidence indicates that most children cease to use physical aggression during the course of childhood, but that a minority fails to do so. This group is comprised of children with high, stable levels of PA and is mostly male. Overall, most children use low levels of IA, but there is one group that uses this type of aggression with increasing frequency. This group is mostly female. Importantly, the differences between the sexes are not stable over time. Rather, while the gap between males and females is present during preschool years, it widens considerably during childhood and preadolescence. A review of hypotheses based on evolution, biology and social learning provides critical insight into the origins and development of sex differences in aggression over the life course. We conclude by arguing that violence in males may be effectively reduced through early, sustained intervention with high-risk mothers.     

Evaluating the effects of birth complications on low self-control in a sample of twins

Gottfredson and Hirschi's general theory has generated an abundance of research examining the effects of low self-control on crime and analogous behaviors. Less research, however, has focused on the factors that contribute to the development of low self-control. Gottfredson and Hirschi maintain that ineffective parents are the sole cause for the emergence of low self-control. At the same time, they disregard the possibility that low self-control has a biological or genetic component. This article extends prior research and examines the effects of birth complications and parental involvement on low self-control. Using a sample of twin children, the authors find that parental involvement is only weakly and inconsistently related to low self-control. On the other hand, although most of the birth complications had no appreciable effect on low self-control, anoxia (oxygen starvation) emerged as the strongest and most consistent predictor of low self-control.     

A cross-cultural validation of self-control theory

Several core propositions of self-control theory were tested utilizing self-reported data gathered from university students in Malta, Trinidad and Tobago, and the United States. The results provide some support for the claim that ineffective parenting decreases self-control and strong support for the proposition that self-control increases deviant behavior. Additionally, tests of slope differences for key theoretical variables across samples generated findings that are largely consistent with the theory's cultural invariance thesis. Implications of the findings from this multinational test are discussed.     

Assessment of the methodology for estimating ridge density in fingerprints and its forensic application

In recent times, some studies have explored the forensic application of dermatoglyphic traits such as the epidermal ridge breadth or ridge density (RD) toward the inference of sex and population from fingerprints of unknown origin, as it has been demonstrated that there exist significant differences of fingerprints between sexes and between populations. Part of the population differences found between these studies could be of methodological nature, due both to the lack of standardisation in the position of the counting area, as well as to the differences in the method used for obtaining the fingerprint. Therefore, the aim of this study was to check whether there are differences between the RD of fingerprints depending on where the counting area is placed and how the fingerprints are obtained. Fingerprints of each finger were obtained from 102 adult Spanish subjects (50 females and 52 males), using two methods (plain and rolled). The ridge density of each fingerprint was assessed in five different areas of the dactylogram: two closer to the core area (one on the radial and the other on the ulnar side), two closer to the outermost area of each of the sides (radial and ulnar), and another one in the proximal region of the fingertip. Regardless of the method used and of the position of the counting area, thumbs and forefingers show a higher RD than middle, ring, and little fingers in both sexes, and females present a higher RD than males in all areas and fingers. In both males and females, RD values on the core region are higher than those on the outer region, irrespective of the technique of fingerprinting used (rolled or plain). Regardless of the sex and location of the count area (core or outer), the rolled fingerprints exhibit RD greater than that of the plain ones in both radial and proximal areas, whereas the trend is inverted in the ulnar area, where rolled fingerprints demonstrate RD lesser than that of the plain ones. Therefore, in order for the results of different studies to be comparable, it is necessary to standardise the position of the count area and to use the same method of obtaining the fingerprint, especially when involving a forensic application.     

THE INTERACTION OF RACE, GENDER, AND AGE IN CRIMINAL SENTENCING: THE PUNISHMENT COST OF BEING YOUNG, BLACK, AND MALE

Prior theory and research on sentencing oversimplify the role of race, gender and age in judicial decision making. In this article we present a "focal concerns" theory of judicial decision making to frame hypotheses regarding the effects on sentencing of these social statuses, both singly and in combination. Analyzing statewide sentencing outcomes in Pennsylvania for 1989–1992, we find that, net of controls: (1) young black males are sentenced more harshly than any other group, (2) race is most influential in the sentencing of younger rather than older males, (3) the influence of offender's age on sentencing is greater among males than females, and (4) the main effects of race, gender, and age are more modest compared to the very large differences in sentencing outcomes across certain age-race-gender combinations. These findings demonstrate the importance of considering the joint effects of race, gender, and age on sentencing, and of using interactive rather than additive models.     

Sex Determination from the Frontal Bone: A Geometric Morphometric Study

Sex estimation in human skeletal remains when using the cranium through traditional methods is a fundamental pillar in human identification; however, it may be possible to incur in a margin of error due because of the state of preservation in incomplete or fragmented remains. The aim of this investigation was sex estimation through the geometric morphometric analysis of the frontal bone. The sample employed 60 lateral radiographs of adult subjects of both sexes (30 males and 30 females), aged between 18 and 40 years, with mean age for males of 28 ± 4 and 30 ± 6 years for females. Thin‐plate splines evidenced strong expansion of the glabellar region in males and contraction in females. No significant differences were found between sexes with respect to size. The findings suggest differences in shape and size in the glabellar region, besides reaffirming the use of geometric morphometrics as a quantitative method in sex estimation.     

Sex Differences in Age Patterns of Delinquent/Criminal Careers: Results from Poisson Latent Class Analyses of the Philadelphia Cohort Study

Applications of latent class analyses to the study of criminal careers have yielded results with implications for criminological theory. Distinct latent classes of individuals within various samples have been identified based upon the similarity of individuals with respect to their rate of offending across the teen and adult years, net of the effects of other regressors. In previous research on samples of males taken from the cities of London and Philadelphia, four and five such categories have been identified respectively, ranging from a group of nonoffenders to a group of chronic offenders. However, the question of whether similar findings hold for females has not been adequately addressed, in part due to the scarcity of longitudinal samples with sizable female populations. Data from the Second Philadelphia Cohort are used to address this and related questions. First, are there latent classes of female offenders? Second, if such categories do exist, how do they compare? Third, how do classes of male and female offenders compare on key measures of criminal careers? Analyses of the samples yield differing numbers of classes for males and females. Gender invariances as well as differences in patterns of offending are also found and are discussed.
