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.
METHODS: Two electronic academic databases were searched: Scopus and Web of Science (WoS) using specific keywords as search terms derived from the PCC framework with no specific time limit. The search strategy was developed based on the JBI Manual for Evidence Synthesis and utilised the PRISMA-ScR guidelines. Data on the risk of violence, intervening factors, and aggressive behavior were extracted from the included studies. Further analysis was performed whereby similar data were grouped and synthesised together.
RESULTS: The initial search produced 342 studies. However, only nine studies fulfilled the inclusion criteria. The nine studies included 1,068 adult forensic inpatients from various psychiatric hospitals. Only mediation studies reported significant mechanisms of influence between the risk of violence and aggressive behavior. It is postulated that the human agency factor may be the underlying factor that influences a person's functioning and the subsequent series of events between the risk of violence and aggression.
CONCLUSIONS: In light of the paucity of evidence in this area, a generalised conclusion cannot be established. More studies are warranted to address the gaps before conclusive recommendations can be proposed to the relevant stakeholders.
RESULTS: Scanning electron microscopy images demonstrated successful attachments of NBR onto the constituents of fingerprints on the substrates. The highest average quality of visualised fingerprints was attained at the optimum condition (100 mg of CRL; 75 mg of acid-functionalised multi-walled carbon nanotubes; 5 h of immobilisation). The NBR produced comparable average quality of fingerprints with the commercially available small particle reagent, even after 4 weeks of storage (without any preservatives) in both chilled and sultry conditions. The NBR was sensitive enough to visualise the increasingly weaker fingerprints, particularly on glass slides.
CONCLUSION: The optimised novel NBR could be the relatively greener option for visualising latent fingerprints on wet, non-porous substrates for forensic applications.
METHODS: A cross-sectional study involving 290 medical undergraduates was conducted in a Malaysian university. The questionnaires on the attitude towards suicide and general help-seeking behavior were used as research instruments.
RESULTS: The mean age of the participants was 22.4 years. Participants who did psychiatry posting indicated a greater tendency to agree on suicide as a way of communication (p = 0.008) than those who did not. Participants previously diagnosed with a psychiatric illness indicated a greater ability to understand and accept suicide (p < 0.001) as well as a greater tendency to agree on the normality of suicide (p = 0.019) than those without a previous diagnosis. Those who attended a suicide prevention program also indicated a greater tendency to agree that loneliness and avoidance could be triggers to suicide (p = 0.037) than those who did not. No correlation was found between the "attitude towards suicide" and "general help-seeking behavior" variable.
CONCLUSION: Education programs in suicide prevention and management need to be incorporated early into the undergraduate medical curriculum to cultivate a more positive attitude towards suicide and help-seeking behavior.
