Coping with urban crime: women's use of precautionary behaviors.
This investigation examines the impact of three sets of variables, neighborhood conditions, psychological factors, and life circumstances, on women's use of behaviors designed to protect themselves from criminal victimization. Participants in the study were 299 women living in Philadelphia, Chicago, and San Francisco. Two types of precautionary behaviors were identified: avoiding dangerous situations (e.g., by not going out alone at night) and managing risks in the face of possible danger (e.g., by asking repairmen for identification). The three sets of variables were better able to predict avoidance than risk-management behavior. Commonality analyses revealed that psychological factors uniquely accounted for the largest proportion of the variance in the use of both types of precautions. In multiple regression analyses, fear, perceived physical competence, race, and education were significant predictors of avoidance, while fear and perceptions of local social disorder had significant regression effects on risk-management. Implications of the results for research and social policies regarding the impact of crime on communities are discussed, and this area is suggested as a rich context for the exploration of styles of coping with environmental stressors.

Social support and victims of crime: matching event, support, and outcome.
Investigated the buffering properties of six types of social support (three perceived, three received) with regard to four psychological consequences (depression, anxiety, fear of crime, hostility) of criminal victimization (violent crime, property crime). These relationships were examined using longitudinal data collected from a sample composed of representative subsamples of victims and nonvictims. Effects of the perceived support measures (perceived appraisal support, perceived tangible support, self-esteem) were more pervasive than those of the received support measures (received informational support, received tangible support, received emotional support). Perceived support consistently exhibited buffering effects, protecting both violent and property crime victims against various symptoms they would have otherwise experienced. The stress-buffering capabilities of received support were limited to informational and tangible help protecting victims of violence from experiencing excessive fear. These findings are discussed in the context of recent theoretical developments concerning the stress-support matching hypothesis.

Are researchers bound by child abuse reporting laws?
OBJECTIVE: To discuss issues concerning mandatory reporting of child abuse in research settings. METHOD: An overview of existing Federal and State statutes regarding mandatory reporting of child abuse is presented. A critical review of the literature addresses the following issues: (1) whether researchers have a moral duty to place the health and safety of children above concerns about confidentiality and the benefits of obtaining new knowledge; (2) whether the Certificate of Confidentiality preempts reporting requirements; (3) whether researchers who are not health professionals (such as child developmentalists, psychobiologists, neuroscientists) should be required to report; and (4) whether researchers should be required to expand their protocols to include more in-depth investigation of potential abuse. RESULTS: Existing child abuse reporting laws do not specifically designate researchers as among the category of individuals mandated to report suspected child abuse. Currently, Human Subject Protection Committees and Federal funding agencies are tending to interpret reporting laws as applying to researchers, including requiring that research subjects are informed of this responsibility in consenting procedures. It is unclear whether the Certificate of Confidentiality preempts child abuse reporting laws. CONCLUSION: The authors recommend that legislatures specifically designate researchers as mandated reporters to ensure more uniform reporting practices in research settings. For both investigators and Human Subject Protection Committees, inclusion of researchers among the categories of those mandated to report would also help address issues of immunity from civil and criminal liability for "good faith" reports that turn out to be false and injurious.

The pedophilic offender with antisocial character.
The purpose of the study was to clarify how pedophilic offenders with antisocial character (psychopathy) differ from "ordinary" pedophilic offenders, among whom there are many persons with immaturity and contact difficulties. For this purpose all pedophilia cases subjected to mental examination during a period of 25 years were investigated. Of these 81 cases, 38 could be regarded as antisocial characters on the basis of the current diagnostic criteria. The others were regarded as controls. The criminals with antisocial character had also been involved in other kinds of crimes and had had hyperactivity problems more often than controls. The controls were often immature, had a low intelligence, and were less able to have relations with adult people than were antisocial characters. However, according to the present results, these features might also make criminals with antisocial character more susceptible to pedophilia.

[Institutional handling of criminal measures in sexual abuse. Results of a survey of experts].
A broad spectrum of very different institutions is confronted with the problem of sexual child abuse. So far, only a few systematic descriptions of institutional interventions and their impact on sexually abused children exist. In this article, first results are presented of a study investigating "individual and institutional reactions on sexual child abuse'. In dealing with this problem legal provisions are of special importance. The results presented are based on data obtained from questionnaires and qualitative interviews with experts (median of vocation experience: 8 years) in two german cities (berlin/cologne). Questionnaires were filled in by 195 experts from the entire institutional spectrum (counselors, clinical centres, youth welfare departments, public prosecutors, courts of justice, police), of whom 40 additionally took part in a detailed interview. This article focuses on the question, how different institutions handle legal provisions. The use of criminal law exemplarily shows the different impact of legal provisions on the interventions of counselors. The close connection between the assessment of legal interventions and counseling concepts could be shown at the example of the allegedly homogeneous group of specific counselors.

Effects of methylphenidate on impulsive choice in adult humans.
RATIONALE: Several studies with nonhumans and humans have shown that stimulants decrease impulsive choices on delay-to-reinforcement (self-control) procedures. Little is known, however, about the effects of the stimulant methylphenidate on choice for delayed reinforcers in humans. OBJECTIVES: The present study was designed to investigate the effects of acute methylphenidate administrations on impulsive responding in adult humans on a delay-to-reinforcement task. METHODS: Eleven adult males with a history of criminal behavior but no history of attention-deficit hyperactivity disorder (ADHD) participated. Impulsive responding was measured using an adjusting-delay procedure in which subjects were presented with repeated choices between a small amount of money delivered after a short delay and a larger amount of money delivered after a delay that adjusted as a function of previous choices. Subjects were exposed to four experimental sessions each day of participation and 60 min prior to the first daily session received placebo or 0.15, 0.30, or 0.60 mg/kg methylphenidate. Stable choice patterns were re-established between each methylphenidate dose. RESULTS: Individuals differed in their sensitivity to methylphenidate, but in over half of the subjects methylphenidate decreased impulsive (i.e., increased the number of self-control choices) and increased the delay to the large reinforcer. The largest increases in self-control choices tended to occur at the 0.30-mg/kg and 0.60-mg/kg doses, and the effects often persisted across multiple daily sessions. In six subjects, under at least one methylphenidate dose, the number of impulsive choices decreased to zero. CONCLUSIONS: Acute methylphenidate administrations tended to decrease the number of impulsive choices in adult humans on an adjusting-delay procedure, although there were substantial individual differences in the sensitivity of choice to methylphenidate. In no case, however, did methylphenidate increase impulsive choices. These results are consistent with several recent laboratory studies with nonhumans and humans showing that stimulants increase preference for large, delayed reinforcers.

The future of forensic and crime scene science. Part II. A UK perspective on forensic science education.
This paper builds on the views presented by the author at 'The Future of Forensic and Crime Scene Science Conference'. Forensic science has become an increasingly prominent area of science within the last 10 years. This increasing prominence together with popularity in the subject has seen the number of undergraduate students studying forensic science related courses at UK Universities increase rapidly in just 5 years and there are no short term signs of this trend reducing. In 2005, there were 450 courses with forensic in the title offered by higher education institutes. Although the forensic community has expressed its concern that job prospects for these students wishing to pursue careers as forensic scientists will be limited numbers of students undertaking science courses have still increased. The increase in students studying forensic science comes in an era of decreasing science numbers in higher education with the potential to produce high calibre science graduates with sought after skills in critical thinking, analysis, interpretation and communication. Technology has continued to advance at a similar pace providing those responsible for managing crime with a need and opportunity to identify and predict new and future applications of science and technology; not just in reducing and detecting crime but also in predicting how technology will be used by criminals in the future. There is therefore a need for forensic science users, providers and educators to identify the knowledge and skills required by forensic scientists and crime investigators of the future to ensure that technology continues to be used and applied to its full advantage. This provides universities an opportunity to contribute to the development of both the practice and practitioners of forensic science. This paper outlines the current issues facing universities in relation to forensic science and identifies their future role in providing high quality relevant courses for future forensic practitioners; developing current forensic practitioners through their participation in applied research, short courses, conferences and qualifications linked to professional practice; and supporting and developing the practice of forensic and crime scene science, through the identification, engagement and dissemination of pure and applied research.

A program analysis of Esuba: helping turn abuse around for inmates.
This investigation is an empirical evaluation of Esuba, an abuse awareness program implemented in the Florida correctional system. Research has indicated a link between violent and abusive behavior and criminal activity. This study specifically addressed whether the Esuba program had an impact on offenders' self-esteem, stability of self, faith in people, and sensitivity to criticism as measured by the Rosenberg Self-Esteem Scale. The results from the application of the Esuba program to an incarcerated offender population are encouraging. The results suggest that the Esuba program does appear to significantly increase offenders' emotional self-preservation.

[A hopeless case?].
In a hollow covered with earth, a herb gatherer discovered a severely decomposed corpse mutilated by scavenging animals. Only small areas of the skin had remained intact. A conspicuous tattoo could still be distinguished on the left upper arm. Despite concrete evidence of violence (fracture in the occipital bone, subdural hemorrhage with a volume of 20 ml), the exact cause of death could no longer be established. Police enquiries identified a person in whom such a conspicuous tattoo had been photographed in an earlier criminal case. Eventually, the deceased person could be identified by DNA analysis of a stored blood alcohol specimen. Considered together, the autopsy findings and the results of the investigation of traces of blood on the putative tool used in the crime indicated that the man had been struck dead and the body had afterwards been buried in the wood. Although the prospects of success had been initially slight, it was not only possible to identify the victim, but also to reconstruct the crime.

Image processing by computer analysis--potential use and application in civil and criminal litigation.
The image processing by computer analysis has established a data base for applications in the industrial world. Testing has proved that the same system can provide documentation and evidence in all facets of modern day life. The medicolegal aspects in civil and criminal litigation are no exception. The primary function of the image processing system is to derive all of the information available from the image being processed. The process will extract this information in an unbiased manner, based solely on the physics of reflected light energy. The computer will analyze this information and present it in pictorial form, with mathematical data to support the form presented. This information can be presented in the courtroom with full credibility as an unbiased, reliable witness. New scientific techniques shown in the courtroom are subject to their validity being proven. Past imaging techniques shown in the courtroom have made the conventional rules of evidence more difficult because of the different informational content and format required for presentation of these data. I believe the manner in which the evidence can now be presented in pictorial form will simplify the acceptance. Everyone, including the layman, the judge, and the jury, will be able to identify and understand the implications of the before and after changes to the image being presented. In this article, I have mentioned just some of the ways in which image processing by computer analysis can be useful in civil and criminal litigation areas: existing photographic evidence; forensic reconstruction; correlation of effect evidence with cause of evidence; medical records as legal protection; providing evidence of circumstance of death; child abuse, with tracking over time to prevent death; investigation of operating room associated deaths; detection of blood at the scene of the crime and on suspected objects; use of scales at the scene of the crime; providing medicolegal evidence beyond today's technology; and a new theory and technique on using polygraph information in litigation. I am sure that the professionals in the forensic field will be able to think of many more applications where the image processing by computer analysis tool will be able to provide solutions to complex problems. The next time you say to yourself, "I wish they would have preserved this," or, "It's too bad they didn't do an autopsy," think of this new tool that is available to help you get the documentation and answers that will stand up to the scrutiny of the civil and criminal litigation system.

Crime scene analysis and the escalation of violence in serial rape.
The current study examines the crime scene behavior manifest by 108 serial rapists responsible for the perpetration of 565 rapes across various cities within the US. The goal of the current study is to identify which aspects of crime scene behavior reported to law enforcement by the victim are most useful in predicting, early in a series of offenses, which rapists are most likely to escalate into higher and, at times, life threatening levels of violence. Using 58 scales that quantify the verbal, physical, and sexual behavior manifest by a rapist in his interaction with his victim during his first reported rape and 36 modal variables that summarized approach, timing, demographics, and weapon usage across the series of rapes, the study attempts to differentiate between those rapists who escalate in their use of blunt force (Increasers) from those who do not (Non-Increasers). A logistic regression indicates that rapists who are white rather than of minority status and who, at the time of their first reported rape, rape their victims for longer periods of time and use more profanity are more likely to escalate in their level of blunt force than those rapists who do not exhibit these behaviors. The relevance of this type of predictive framework for law enforcement in its attempts to prioritize particular investigations is discussed.

Co-witness information can have immediate effects on eyewitness memory reports.
When questioning a reluctant witness, investigators sometimes encourage the witness by providing information about what other witnesses have said. Three experiments were conducted to test the combined effects of such co-witness information and suggestive questioning on the accuracy of eyewitness memory reports. Experiment 1 was analogous to the experience of a witness who receives information from an interviewer or questioner about what other witnesses have already said, whereas Experiments 2 and 3 simulated the situation in which a witness receives information directly from a co-witness. In all three experiments, when participants received incorrect information about a co-witness's response, they were significantly more likely to give that incorrect response than if they received no co-witness information. This effect persevered in a delayed memory test 48 h after the initial questioning session in Experiment 3. Accuracy rates were lowest of all when incorrect co-witness information was paired with questioning that suggested an incorrect response. These results have implications not only for the immediate effects on the accuracy of witnesses' memory reports, but also for the impact that even one such inaccurate report can have on the manner in which a case is investigated by the police or other authorities.

Fitness to stand trial: characteristics of remands since the 1992 Criminal Code amendments.
OBJECTIVE: To examine the characteristics of a sample of remands after the introduction of the 1992 Criminal Code amendments, to compare those deemed fit with those deemed unfit as the result of an institution-based evaluation of fitness, and to determine the impact of the Code changes on one's detention period by investigating the length of time that individuals were held on remand. METHOD: File information was collected and analyzed for 180 males who were remanded for inpatient evaluations of their fitness to stand trial between October 1994 and July 1995. RESULTS: The results indicated that remanded defendants are more likely to be single, unemployed, and living alone and that unfit defendants are significantly more likely to have never been married. As well, individuals who were found to be unfit to stand trial were significantly less likely to have been diagnosed with a drug- or alcohol-use disorder and were 4 times more likely to have been diagnosed with a psychotic disorder. The results also indicated that while the 1992 Criminal Code revisions called for a 5-day evaluation period, it appears that this is rarely accomplished, and, in fact, the average length of time for an assessment of fitness is 23 days. Finally, the majority of remanded individuals are certified and treated with psychotropic medications while on remand. CONCLUSION: The results of this study suggest that the fitness remand period is being used for purposes other than assessing fitness.

A neural network investigation of the crucial facets of urban sustainability.
This paper focuses on the concept of a sustainable city and its theoretical implications for the Italian urban system. Urban sustainability is based on positive interactions among three different urban subsystems: social, economic and physical, where social well-being coexists with economic development and environmental quality. This utopian scenario does not appear in the existing cities. The aesthetic quality of natural and man-made environment is often associated with marginality and poverty, labor market variety and urban efficiency coexisting with pollution, criminality and high settlement costs. Moreover, since each city differs institutionally, historically, culturally and economically, few attempts have been implemented to build a comparative synthetic vision of the urban sustainability in different cities. The interactions among these selected systems are complex and unpredictable and present the opportunity for a new methodology of scientific investigation: the connectionistic approach. The dual aim of this study is to: investigate the underlying relationships among the three subsystems with a set of social, economic and physical attributes of the chief towns of a Province in Italy and ; verify if this underlying structure could reproduce the heterogeneity of urban realities, allowing one to distinguish groups of cities with different assets or drawbacks in their sustainability. The Data Base (DB), composed of 43 attributes for 95 cities, was processed by Self-Reflexive Neural Networks (SRNN) (Buscema, 1995). These Networks are a useful instrument of investigation and analogic questioning of the Data Base. Once the SRNN has learned the structure of the weights from the DB, by querying the network with the maximization or minimization of specific groups of attributes, it is possible to read the related properties and to rank the cities' urban profile.

Teaching adolescents and adults about adjudicative proceedings: a comparison of pre- and post-teaching scores on the MacCAT-CA.
The current study investigated whether teaching was associated with improved legal understanding among adolescents and adults. Participants included 927 youth and 466 young adults, who completed the MacArthur Competence Assessment Tool-Criminal Adjudication, the Massachusetts Youth Screening Instrument-Second Version, and the Wechsler Abbreviated Scale of Intelligence. Adolescents aged 13 and younger were less likely than older individuals to improve with teaching. IQ score was positively associated with improvements following teaching, and individuals from ethnic minority groups showed greater improvements following teaching than non-Hispanic Caucasians. The implications of these findings are discussed.
