Minimum velocity necessary for nonconventional projectiles to penetrate the eye: an experimental study using pig eyes

To satisfy the Criminal Code of Canada's definition of a firearm, a barreled weapon must be capable of causing serious bodily injury or death to a person. Canadian courts have accepted the forensically established criteria of "penetration or rupture of an eye" as serious bodily injury. The minimal velocity of nonconventional ammunition required to penetrate the eye including airsoft projectiles has yet to be established. To establish minimal threshold requirements for eye penetration, empirical tests were conducted using a variety of airsoft projectiles. Using the data obtained from these tests, and previous research using "air gun" projectiles, an "energy density" parameter was calculated for the minimum penetration threshold of an eye. Airsoft guns capable of achieving velocities in excess of 99 m/s (325 ft/s) using conventional 6-mm airsoft ammunition will satisfy the forensically established criteria of "serious bodily injury." The energy density parameter for typical 6-mm plastic airsoft projectiles is 4.3 to 4.8 J/cm2. This calculation also encompasses 4.5-mm steel BBs.     

Laboratory simulation and bias in the study of juror behavior

Theoretical speculation and meta-analysis suggest that the strength of treatment effects (e.g., defendant attractiveness) may become weaker as the experimental simulation becomes more realistic and complex. In order to test this hypothesis, various levels of biasing pretrial publicity were combined with both a short and a long trial. Results provided no support for the contention that treatment effects act differently as a function of the length of the stimulus trial in which they are embedded. Rather, it is suggested that treatments used in simplified jury simulations may often show similar effects when examined in more realistic, complex settingsif the treatments are comparable.This research was supported by NSF Research grant No. SES 8419944 to the second author, John Carroll, and James Alfini.

Velocity necessary for a BB to penetrate the eye: an experimental study using pig eyes

PURPOSE: To determine the V-50 threshold velocity needed for a steel BB to penetrate the eye of a 230-pound pig. METHOD: BBs were shot at a distance of 10 feet into the corneas of pig eyes with a pump-action BB gun. RESULTS: The V-50 velocity for corneal penetration and serious disruption of the eye was found to be 246 ft/sec. CONCLUSION: Due to the nearly identical size and anatomy of the human eye to the pig eyes used in this study, it is felt that 246 ft/sec is a reasonable approximation of the velocity needed to penetrate the human eye.     

State-Organized Crime,International Law and Structural Contradictions

Following the trail blazed by Bill Chambliss in his 1988 Presidential Address to the American Society of Criminology, this article engages two interrelated issues concerning the concept of state-organized crime that he pioneered. First, the article develops Chambliss’s argument that criminologists should define state crime as behavior that violates international agreements and principles established in the courts and treaties of international bodies. Second, although Chambliss effectively argued that international law “on the books” provides a framework of substantive concepts and categories that allows criminologists to define certain state actions as a form of crime, “in action” international laws fail to provide legal accountability for states and protection for victims. This article demonstrates, however, that Chambliss’s structural contradictions theory of law can help to explain this paradox.     

Advance directives in bipolar disorder, a cognitive behavioural conceptualization

Mental Health Advance Directives (MHADs) are potentially useful for bipolar patients due to the episodic characteristic of their disease. An interest for the development of a Cognitive Behavioural Therapy (CBT) approach in the creation process of MHADs arises because of a lack of efficiency of the non-collaborative processes, the potential impact of psychopathology and the awareness of the illness in MHADs' content, the link between the patient's directives interest and the case manager's interest, and the lower interest reported by the potentially high MHADs beneficiary. The CBT intervention in the MHADs creation process that is proposed in this article is based on: the self-determination model for adherence, the cognitive representation of illness model, and the concordance model. The principles of the intervention were adapted from Motivational interviewing's (MI), emphasising personal choice and responsibility, and focusing on the patient's concerns about the treatment through Socratic dialogue. During the course of 2004, 20 advance directives written by patients (17 with bipolar disorder, 3 with schizoaffective disorder) have been collected following the described intervention. Therefore, this intervention seems to be relevant for patients with bipolar disorder.

LONG-TERM FOLLOW-UP OF A COURT-BASED INTERVENTION FOR DIVORCING PARENTS

This study investigated whether participation in an educational program for divorcing parents is associated with a lower incidence of relitigating divorce-related decisions over time. A systematic review of court records indicated that couples who attended this program (n = 159) in central Illinois were just as likely as those in the control group (n = 43) to relitigate over a 6-year period. Furthermore, county-wide rates of relitigation increased from 2 years before to 3 years after the program's introduction. However, reports obtained from participating families suggest that the program may serve an important function for families in which there is a high risk of triangulating children into postdivorce conflict.
