Analysis of Glass Fracture Pattern on Soda Lime and Tempered Glass Caused by Shotgun Bullet Impact

@#Introduction: Broken glass exhibits unique fracture patterns depend upon the nature of the impact. The fracture patterns provide information like point and angle of impact, direction of force and sequence of firing. Recent studies have shown that the use of shotgun in Malaysia is increasing, yet, the relationship existing among the fracture pattern and the projectile impact factors are not well documented. The objective was to analyse the fracture characteristics on different glass types of variable thickness and distance made by shotgun ammunition. Methods: Soda lime and tempered glass panel with dimension of 12’x 12’ with 3 or 4 mm thickness were shot from various distances of 4, 6 and 8 m from the muzzle end of the shotgun. Samples were analysed under fixed parameters and observations were recorded. Results: It is found that the bullet hole diameter of 4 mm tempered glass were larger compared to 4 mm soda lime glass ranged from 14.33 to 24.17 cm as distance increased. Tempered glass surface also exhibited dicing fragments unlike soda lime glass where only radial fracture patterns are evident. This can be attributed to high inherent strength and ductility that makes the tempered glass remarkably resistant to external force. Conclusion: The findings from this study can lead to distinguish the type of glass through examination of fracture patterns, whether it is soda lime silica or tempered glass. The type of glass and the source of impact can be determined using the fragments, no reconstruction necessary.

Mechanical profiles of murder and murderers: An extensive review

@#Introduction: Murder is an extreme form of violent crime which occurs across all social, cultural, and ethnic spheres. It is therefore, crucial to understand the nature and the extent of mechanical profiles of murder and murderers. The purpose of this article is to review such critical aspects of murder in a nutshell. Methods: An archival research methodology was employed in this study where relevant search for literatures on these mechanical aspects related to murder was made across search engines such as Google Scholar and Elsevier with relevant articles selected for this review. Results and Discussion: This review discusses in an in-depth manner, pivotal mechanical profiles which include motives, methods of killing, choice of weapon, settings, targeted body parts, and murder victim concealment. In-depth understanding of each mechanical aspect offers an opportunity to the public at large to expand their knowledge on murder prevention manners which is vital for crime prevention efforts in the future.

Psychological Asssessment and Management of Trauma Survivors / Jurnal Sains Kesihatan Malaysia

This article describes the psychological assessment and management for trauma survivors. An appropriate assessment is essential to ensure that psychotherapy, behavioural treatment and support networks are sufficient for the trauma survivor’s long-term needs or until the individual is capable of functioning normally. In line with the mission of the American Psychological Association (APA) Division 56 (Trauma Psychology), this article suggests practical guidelines for psychologists, counselors and social health workers. Issues discussed include definition of trauma, post-incident symptoms and trauma recovery. Among the types of trauma examined were cancer, sudden death, sexual abuse and AIDS. A working model to initiate assessment was presented together with projected treatment modalities. Additionally, this article also incorporates knowledge on profesional and public education about dissociation, trauma and trauma related disorders besides strengthening knowledge about trauma, dissociation and disorders related to chronic trauma. This article also supports communication and cooperation among clinicians and other profesionals in the field of dissociation and trauma as well as stimulating national and international research projects. Different individuals react differently to a similar event. A person may experience trauma as a reaction to the event while another person may not. Not all individuals who experience a potentially traumatic event will be psychologically traumatised.

Linking Psychological Traits With Criminal Behaviour: A Review

Objective: Apart from environmental and social factors, psychological traits is largely linked with criminal and delinquent behaviour. The purpose of this article is to review four critical psychological traits of individuals that may lead to criminal behaviour in a nutshell. Methods: An archival research methodology was employed in this study where relevant search for literatures on these four psychological traits was made across search engines such as Google Scholar with relevant articles selected for this review. The literatures were microscopically reviewed in order to demonstrate the linkage between psychological traits and criminal behaviour. Results: Four psychological traits: personality trait, low self-control, aggression behaviour, and cognitive distortion were chosen to address such linkages. All these four traits were discussed thoroughly in relation to crime and criminality contexts. Conclusion: It is crucial to understand the role of these traits and in-depth understanding of each psychological trait with relation of criminal behaviour offers and opportunity to the public at large to expand their knowledge on the importance of practicing and equipping oneself with healthy psychological traits to hinder criminal and delinquent acts.

Psychological traits underlying different killing methods amongMalaysian male murderers

Murder is the most notorious crime that violates religious, social and cultural norms. Examining the types and number of different killing methods that used are pivotal in a murder case. However, the psychological traits underlying specific and multiple killing methods are still understudied. The present study attempts to fill this gap in knowledge by identifying the underlying psychological traits of different killing methods among Malaysian murderers. The study adapted an observational cross-sectional methodology using a guided self-administered questionnaire for data collection. The sampling frame consisted of 71 Malaysian male murderers from 11 Malaysian prisons who were selected using purposive sampling method. The participants were also asked to provide the types and number of different killing methods used to kill their respective victims. An independent sample t-test was performed to establish the mean score difference of psychological traits between the murderers who used single and multiple types of killing methods. Kruskal-Wallis tests were carried out to ascertain the psychological trait differences between specific types of killing methods. The results suggest that specific psychological traits underlie the type and number of different killing methods used during murder. The majority (88.7%) of murderers used a single method of killing. Multiple methods of killing was evident in ‘premeditated’ murder compared to ‘passion’ murder, and revenge was a common motive. Examples of multiple methods are combinations of stabbing and strangulation or slashing and physical force. An exception was premeditated murder committed with shooting, when it was usually a single method, attributed to the high lethality of firearms. Shooting was also notable when the motive was financial gain or related to drug dealing. Murderers who used multiple killing methods were more aggressive and sadistic than those who used a single killing method. Those who used multiple methods or slashing also displayed a higher level of minimisation traits. Despite its limitations, this study has provided some light on the underlying psychological traits of different killing methods which is useful in the field of criminology.

Associations Between Personality Traits And Aggression Among Malay Adult Male Inmates In Malaysia

Objective: A sizable body of criminology literature has suggested that personality factors are critical to the development of aggressive behaviour. While research on personality focusing on aggression often revolves on "Eynseck Three Factor Model" and "Big Five Model", research on "Alternative Five Factor Model" (AFFM) is rather inadequate. Objective: The present study aimed to examine the association between five types of personality traits and subscales of aggression. Methods: This observational cross-sectional study was conducted in two prisons in Peninsular Malaysia among 198 Malay adult male inmates. The participants were selected based on the purposive sampling method from those who were convicted for various types of crime. Two psychometric instruments adapted to the Malaysian context were used: Malay version of Zuckerman-Kuhlman Personality Questionnaire-40-Cross Culture (ZKPQ-M-40-CC) and Aggression Questionnaire (AQ-M). Pearson correlation coefficient test was conducted to determine the association between five types of personality traits and subscales of aggression. Results: The results showed that there was a significant association between certain types of personality traits and subscales of aggression. The results were discussed in relation to theory and the context of crime. Conclusion: There is evidence that personality traits are linked to aggressive behaviour which may lead a person to commit offenses.
