A Partial Test of Moffitt’s Developmental Taxonomy: Examining the Role of Genetic Risk

A developing line of research indicates that behavioral patterns associated with the typologies identified in Moffitt’s developmental taxonomy may be influenced by genetic factors. Based on these findings, the current study examines whether Moffitt’s etiological explanations of life-course persistent offenders, adolescence-limited offenders, and abstainers have merit after controlling for genetic influences. To do so, a sample of twins drawn from the National Longitudinal Study of Adolescent Health were examined. The results revealed that genetic influences significantly predicted entry into each of the typologies identified by Moffitt even after controlling for theoretically relevant factors. Implications of the findings and suggestions for future research are discussed.     

SOCIOLOGICAL AND HUMAN DEVELOPMENTAL EXPLANATIONS OF CRIME: CONFLICT OR CONSENSUS?*

This paper examines multidisciplinary correlates of delinquency in an attempt to integrate sociological and environmental theories of crime with human developmental and biological explanations of crime. Structural equation models are applied to assess links among biological. psychological, and environmental variables collected prospectively from birth through age 17 on a sample of 800 black children at high risk for learning and behavioral disorders. Results show that for both males and females, aggression and disciplinary problems in school during adolescence are the strongest predictors of repeat offense behavior. Whereas school achievement and family income and stability are also significant predictors of delinquency for males, early physical development is the next strongest predictor for females. Results indicate that some effects on delinquency also vary during different ages. It is suggested that behavioral and learning disorders have both sociological and developmental correlates and that adequate educational resources are necessary to ensure channels of “legitimate opportunities” for high -risk youths.     

Effects of genetic and environmental explanations of psychopathy and gender on perceptions of criminal behaviors

Genetic/biological evidence is increasingly introduced into courtrooms but findings regarding its impact are mixed. This study integrates research on psychopathy and the use of genetic evidence in legal contexts by considering how information on genetic causal accounts of psychopathy affect perceptions of culpability, recidivism, amenability to treatment, and sentencing severity. Perpetrator gender was examined as a moderator. Two-hundred thirty-eight undergraduates read a hypothetical violent crime vignette and mock expert testimony regarding psychopathy. The testimony included a diagnosis only, or a diagnosis plus genetic or environmental explanations of the etiology of psychopathy. Results indicated that a genetic account of psychopathy was not clearly perceived as aggravating or mitigating such that participants were more lenient in their perceptions of culpability yet more punitive in their sentencing recommendations when perpetrators were described to have genetically-caused psychopathy. An environmental account of psychopathy was mitigating but only for sentencing severity. In addition, although participants were more lenient in sentencing male and female perpetrators when provided with an environmental cause of psychopathy, participants judged male perpetrators most harshly when provided with a genetic cause of psychopathy. Implications of the relations between etiology and gender in legal decision-making are discussed.     

Identity, genealogy, and the social family: the case of donor insemination

In this paper I discuss whether or not biographical information concerning the sperm donor should be disclosed to children conceived through donor insemination. Policies of disclosure for example in the context of adoption, have been justified on the basis of a notion of identity which emphasizes genetic ties. This notion of identity and the policies of disclosure of information concerning biological parents based on it, have been criticized by many writers, including feminists, as reinforcing explanations of human organization and development based on biological determinism rather than on ideas such as social construction. Further, this notion of identity is seen to emphasize the importance of genetic parenthood over the commitment involved in bringing up a child as a social parent. While agreeing with these criticisms of that particular notion of identity, I argue that the notion of identity as a whole should not be summarily rejected. Rather, it should be re-interpreted using a sociological approach incorporating the notion of narrative. This second narrative notion of identity is developed with reference to the situation of some groups of children, who like those born from donor insemination, generally do not have any knowledge of their biological parent[s], for example adoptees, the children of the disappeared in Argentina and child migrants. In this paper, policies of disclosure which allow these children to gain some knowledge of their biological parents are discussed in light of the two notions of identity. It is argued that disclosure may be justified on the basis of a narrative notion of identity. This allows for the rigid dichotomy created between biological determinism and social construction: the importance of social parents to the child is emphasized, however the desire a child may have to know something about her or his biological parent is not denied or dismissed.     

Behavioral economics and health policy: understanding Medicaid's failure

This Article employs a behavioral economic analysis to understand why Medicaid has failed to improve the health outcomes of its beneficiaries. It begins with a formal economic model of health care consumption and then systematically incorporates a survey of psychosocial variables to formulate explanations for persistent health disparities. This methodology suggests that consulting the literature in health psychology and intertemporal decision theory--empirical sources generally excluded from orthodox economic analysis--provides valuable material to explain certain findings in health econometrics. More significantly, the lessons from this behavioral economic approach generate useful policy considerations for Medicaid policymakers, who largely have neglected psychosocial variables in implementing a health insurance program that rests chiefly on orthodox economic assumptions. The Article's chief contributions include an expansion of the behavioral economic approach to include a host of variables in health psychology, a behavioral refinement of empirical health economics, a behavioral critique of Medicaid policy, and a menu of suggested Medicaid reforms.     

Alternative Strategies for Identifying the Link Between Unemployment and Crime

National-level time series data are a crude tool for distinguishing between two alternative behavioral explanations for a link between unemployment and crime. Consequently, inferences drawn from aggregate time series estimates are likely to be misleading. A more fruitful approach to learning about the link between unemployment and crime would be to utilize a menagerie of different methodological approaches such as cross-section and panel data analysis of less geographically aggregated areas, natural experiments, international data, individual-level data, and ethnography.     

Inevitable, influential, or unnecessary? Exploring the utility of genetic explanation for delinquent behavior

In the field of criminology there have been a few recent articles addressing genetic influence on delinquent behavior. The scarcity of research within the field of criminology into genetic influence may be the result of two intertwined factors: methodological difficulties and the lack of a theoretical framework to guide research. The current research addressed these two issues in determining if genetic factors are a necessary part of the delinquency equation. Using Harris' group socialization theory as a framework, the results from the random effects regression and DF analyses indicated that there was a utility to genetic explanations of delinquent behavior. The results further implicated the importance of gene-environment interactions in understanding the true impact of genetic influence on behavior. Implications of the results are discussed.     

Underwhelmed: hyperbole,regulatory policy,and the genetic revolution

Rapid advances in the field of genetics in recent years have caused some commentators to suggest the emergence of a "genetic revolution." Such advances have been both praised as the "future of medicine" and condemned for encouraging the acceptance in society of laissez-faire eugenics. Yet the effect of technological advances flowing from the science of genetics appear somewhat overstated as few products of the genetic revolution, particularly in the areas of gene therapy and genetic testing, have managed to satisfy scientists' expectations to date. Furthermore, misdirected regulation of such advances can exacerbate the social, legal, and ethical problems associated with genetics, particularly in the context of health care, where issues of human cloning and the use of premature genetic testing technologies dominate current public debate. In this article, the author criticizes the hyperbolic rhetoric surrounding the genetic revolution and calls for a more balanced and informed approach to the development of genetic policies and regulations. Such an approach should include substantial interdisciplinary debate and an active role on the part of government in the identification and communication of accurate information relating to the effects of recent technological advances in the field of genetics.

The Influence of Domestic Violence on Preschooler Behavior and Functioning

Enhancing current explanations of domestic violence exposure effects on child cognitive and behavioral functioning was the purpose of this investigation. Participants were 31 domestic violence exposed and 31 non-exposed children ages 3 to 5 years and their single-parent household mothers. Child-mother pairs were matched for child’s age, gender, and ethnicity, mother’s age and education, and annual family income. Child cognitive and behavioral functioning was assessed via psychological assessment and parent report. The presence of mental health difficulties in mothers was assessed using self-report and clinician-administered instruments. Exposed children showed lower verbal functioning and higher internalizing behaviors than did their non-exposed peers. Exposed mothers displayed greater psychological difficulties than did their counterparts.     

The "new" genetics: emerging medicolegal issues in the prenatal issues in the prenatal diagnosis of hereditary disorders.

Major advances in prenatal genetic diagnosis have occurred in the past few years which pose difficult challenges to the law. This paper raises questions relative to family history taking, genetic counseling, carrier detection, amniocentesis, and prenatal genetic studies, and also raises questions with respect to the rights and responsibilities of the patient, the fetus, the physician, and society in light of such modern advances. Law reform often occurs only after prior harm to an individual, family or group. Perception and delineation of the most important issues in this area should serve to stimulate the development of medicolegal guidelines and corrective legislation prior to the occurrence of a genetic tragedy.     

Paternity Testing Commission of the International Society of Forensic Genetics: recommendations on genetic investigations in paternity cases

The International Society for Forensic Genetics (ISFG) has established a Paternity Testing Commission (PTC) with the purpose of formulating international recommendations concerning genetic investigations in paternity testing. The PTC recommends that paternity testing be performed in accordance with the ISO 17025 standards. The ISO 17025 standards are general standards for testing laboratories and the PTC offers explanations and recommendations concerning selected areas of special importance to paternity testing.

AGE AND RULE-BREAKING IN PRISON A Test of Sociocultural Interpretations

Age differences in rule-breaking have been widely noted and widely explained, but rarely if ever have sociological explanations been subjected to actual test. This study examines such age differences among women in prison and lends support to the notion that age differences are more characteristic of inmates with urban backgrounds than of inmates with rural or small town backgrounds. Moreover, among urban inmates age differences appear to be due to age-related normative orientations and commitments rather than age “itself” or related losses of “energy,”“daring,” or “vigor.” Finally, the study supports recurring arguments that non-constitutional characteristics of inmates can shape normative and behavioral conflict within the prison.     

Neuroscience and behavioral genetics in US criminal law: an empirical analysis

The goal of this study was to examine the growing use of neurological and behavioral genetic evidence by criminal defendants in US criminal law. Judicial opinions issued between 2005–12 that discussed the use of neuroscience or behavioral genetics by criminal defendants were identified, coded and analysed. Criminal defendants are increasingly introducing such evidence to challenge defendants’ competency, the effectiveness of defense counsel at trial, and to mitigate punishment.     

Neuroscientific and behavioral genetic information in criminal cases in the Netherlands

In this contribution an empirical approach is used to gain more insight into the relationship between neuroscience and criminal law. The focus is on case law in the Netherlands. Neuroscientific information and techniques have found their way into the courts of the Netherlands. Furthermore, following an Italian case in which a mentally ill offender received a penalty reduction in part because of a ‘genetic vulnerability for impulsive aggression’, the expectation was expressed that such ‘genetic defenses’ would appear in the Netherlands too. To assess how neuroscientific and behavioral genetic information are used in criminal justice practice in the Netherlands, we systematically collect Dutch criminal cases in which neuroscientific or behavioral genetic information is introduced. Data and case law examples are presented and discussed. Although cases are diverse, several themes appear, such as prefrontal brain damage in relation to criminal responsibility and recidivism risk, and divergent views of the implications of neurobiological knowledge about addiction for judging criminal responsibility. Whereas in the international ‘neurolaw literature’ the emphasis is often on imaging techniques, the Dutch findings also illustrate the role of neuropsychological methods in criminal cases. Finally, there appears to be a clear need of practice oriented instruments and guidelines.     

Forensic implications of biting behavior: a conceptually underdeveloped area of investigation

Within the context of a criminal investigation the human bitemark traditionally provides the forensic dentist with both physical and biological evidence. In recent years, however, examples exist where in addition to discussing physical and biological evidence, expert witnesses have also testified in court regarding the behavioral aspects of biting behavior. Interested in this additional source of evidence, the authors reviewed the research literature from which biting behavior could be explained. The review found a hiatus of empirical knowledge in this respect, with only two papers seemingly related to the topic. With this dearth of knowledge in mind, the authors present a framework for further analysis and tentatively suggest reasons for biting behaviors, using a range of psychological models. The article ends with a cautionary note that vague and often misleading behavioral assumptions must not be applied to bitemark testimony until further data are available.     

Bodies of science and law: forensic DNA profiling, biological bodies, and biopower

How is jurisdiction transferred from an individual's biological body to agents of power such as the police, public prosecutors, and the judiciary, and what happens to these biological bodies when transformed from private into public objects? These questions are examined by analysing bodies situated at the intersection of science and law. More specifically, the transformation of ‘private bodies’ into ‘public bodies’ is analysed by going into the details of forensic DNA profiling in the Dutch jurisdiction. It will be argued that various ‘forensic genetic practices’ enact different forensic genetic bodies'. These enacted forensic genetic bodies are connected with various infringements of civil rights, which become articulated in exploring these forensic genetic bodies’‘normative registers’.     

20 years of research into violence and trauma: past and future developments

This reflection on major developments in the past, present, and future of the wider field of violence and trauma is a personal (and probably biased) sampling of what the authors hold to be important. The authors reviewed advances for victims and perpetrators of violence separately. For victims, the authors note that empirical research has established the potential traumatic impact of violence as well as various predictors of what makes persons vulnerable to adverse psychological consequences. The authors also note that the definitions of violence and trauma have evolved to include such behavioral patterns as stalking. Finally, encouraging evidence regarding the efficacy of exposure-based treatments for victims of violence is reviewed, as well as discouraging evidence regarding the efficacy of single-session debriefing following trauma. For the perpetrators, the importance of individual assessment in planning interventions is underscored, and advances in explicit and implicit assessment techniques are discussed.     

生物基因资源获取和利益分享的国际法规制--兼论对我国基因资源保护的启示

在国际法上,基因资源的获取和利益分享涉及三个主要的国际公约,即《生物多样性公约》(CBD)、《粮食和农业植物遗传资源国际公约》和《TRIPS协议》,其中以CBD为核心,确立了基因资源的国家主权控制、事先知情同意和合理分享利益的原则和制度,确立了基因资源保护机制和产权设定的基本框架,对保护我国的基因资源具有重要的借鉴意义。
